AbinandananSounds familiar?

[Update: Edited out the old title and a sentence in the post.]

* * *

In a post about her Stanford education, Lakshmi Saligram has a short segment on her (engineering) undergrad experience that should sound familiar to many of us:

I did my bachelors degree in Electronics & Communications Engineering (ECE), because anyone who “did well” in class 12 usually opted for this track in India. Since I didn’t know what to do with my life at that time, I did what everyone else did. Very quickly I realized that I hated it, but in the messed-up Indian university system that I studied in, once you selected your field of study, there wasn’t any turning back. So what if you made a mistake? So what if you started liking something else? We don’t care. Just sit, and study. And study I did. I hated it, but my grades never showed it. [...] But there was no love, and now in hindsight I realize, if you don’t love it, you will never learn it.

AbinandananExplaining Privilege

John Scalzi says:

I’ve been thinking of a way to explain to straight white men how life works for them, without invoking the dreaded word “privilege,” to which they react like vampires being fed a garlic tart at high noon. [...]

The result? A multiplayer video game called "The Real World". Here's the intro:

Dudes. Imagine life here in the US — or indeed, pretty much anywhere in the Western world — is a massive role playing game, like World of Warcraft except appallingly mundane, where most quests involve the acquisition of money, cell phones and donuts, although not always at the same time. Let’s call it The Real World. You have installed The Real World on your computer and are about to start playing, but first you go to the settings tab to bind your keys, fiddle with your defaults, and choose the difficulty setting for the game. Got it?

Okay: In the role playing game known as The Real World, “Straight White Male” is the lowest difficulty setting there is.

This means that the default behaviors for almost all the non-player characters in the game are easier on you than they would be otherwise. The default barriers for completions of quests are lower. Your leveling-up thresholds come more quickly. You automatically gain entry to some parts of the map that others have to work for. The game is easier to play, automatically, and when you need help, by default it’s easier to get.

Prasanna GadkariDesign for X

'Kung Fu Panda' was a nice movie to watch. Do you remember the scene when Shifu says,'When you focus on kung fu, when you concentrate... you stink'. Maybe it was funny in the movie, but the sad part is that many designers and even organizations fail to focus on the 'value' when they design products.

Was it really long when you thought, "I wish this were designed in a better way"? Bad designs are often products of losing focus on the main problem that the product is designed for. This is the real 'value' of the product. A simple example is that, a pen should write reasonably well under regular conditions. But some designers focus on other things, like giving it an 'unusual' shape and this too to the extent that it becomes next to impossible to write comfortably with it! So essentially a product should perform a single main function (in this case, writing) and a few auxiliary functions (in this case, comfortable gripping while writing, easy to manufacture are a reasonable price in large numbers, etc). So the main function is the single focus of designing. This is called 'Design for X'.
Design for X is a systematic and structured approach to design a product with some a single tangible objective and several second level objectives. It helps mitigate several factors that affect these objectives.

A simplified guideline for designing for X:
  1. Define 'X'
  2. Try to determine as many factors as possible that affect the 'X'
  3. Make a detailed table (or a diagram) to find out the 'level' of each factor. For the sake of simplicity, you may consider only three levels, like level 1 if 'highly affected', level 2 if moderately and level 3 if slightly affected
  4. Make an 'objective statement' for each of these factors, keeping the 'X' in mind
  5. At the end of the process you will have a 'Design Guideline' document with you for the particular product. This will be your guideline for generating concepts.
  6. Now you may use any creativity techniques to design the product for X. You may need to tweak around so that the idea fits into the secondary objectives too.

Quick example:
There are just too many pens that write smoothly (that's a requirement!) Let us design the pen that is quick to open!
Define X : To design a ball point pen that is quick to open
Factors affecting opening time : Ease of grip on the pen , friction between the parts, force required to open the pen, travel of the part for opening, shape of the pen, method of opening of the pen
Factors influence on design
Level 1 : force required to open the pen, travel of the part for opening, method of opening of the pen
Level 2 : Ease of grip on the pen, friction between the parts
Level 3 : shape of the pen
Design Guidelines for a pen that is quick to open:
Level 1 : Design a mechanism for the pen that will have less distance of travel of the moving part and has less operating force
Level 2 : 1. Design the pen body using ergonomic criteria for ease of gripping for selected population.
             2. Choose the materials that will have less relative friction
Level 3 : Design the geometry of pen so that it will assist in opening
Concept 1 : A gravity operated pen.
Pen is held close till it is in the pocket and when you pull it out of pocket the weight of the refill opens it and a mechanism holds it open. The locking mechanism is disengage when it is kept back.
Level 2 & 3 : See the figure below:
Concept 2 : A ball pen with clip as opening mechanism.
Pen is normally held in pocket by the shirt clip. When you pull this pen out, it will actuate the refill to come out. When you are putting it back, the clip is automatically operated again and the refill is pushed back in
Level 2 & 3 : See the figure below:
Concept 3 : A pen that will open when it is about to start writing
The pen will have an actuating mechanism just below its tip. When the tip is touched on the paper, the mechanism will pull the nib out. In order to store the pen back safely, a small plunger at the back can be pulled, so the refill is in normal storing position.
Level 2 & 3 : See the figure below:

AbinandananAtul Gawande: 200 Years of Surgery

In the New England Journal of Medicine: Two Hundred Years of Surgery. A breezy -- but pain-filled! -- survey of the developments in surgical methods.

Before anesthesia, the sounds of patients thrashing and screaming filled operating rooms. So, from the first use of surgical anesthesia, observers were struck by the stillness and silence. In London, Liston called ether anesthesia a “Yankee dodge” — having seen fads such as hypnotism come and go — but he tried it nonetheless, performing the first amputation with the use of anesthesia, in a 36-year-old butler with a septic knee, 2 months after the publication of Bigelow's report.10 As the historian Richard Hollingham recounts, from the case records, a rubber tube was connected to a flask of ether gas, and the patient was told to breathe through it for 2 or 3 minutes.12 He became motionless and quiet. Throughout the procedure, he did not make a sound or even grimace. “When are you going to begin?” asked the patient a few moments later. He had felt nothing. “This Yankee dodge beats mesmerism hollow,” Liston exclaimed.

It would take a little while for surgeons to discover that the use of anesthesia allowed them time to be meticulous. Despite the advantages of anesthesia, Liston, like many other surgeons, proceeded in his usual lightning-quick and bloody way. Spectators in the operating-theater gallery would still get out their pocket watches to time him. The butler's operation, for instance, took an astonishing 25 seconds from incision to wound closure. (Liston operated so fast that he once accidentally amputated an assistant's fingers along with a patient's leg, according to Hollingham. The patient and the assistant both died of sepsis, and a spectator reportedly died of shock, resulting in the only known procedure with a 300% mortality.)

Prasanna GadkariSurbhi’s Experience : NID - Information and Interface design (IID)




Dear friends,
One of the regular reader of this blog and our friend Surbhi Tak made it successfully to NID - Information and Interface design (IID). Many congratulations to her.

I requested her to share her experience and this is what she has to say about it… almost in poetic way!


Who am I?    A successful NID student
Who was I?  ( till 4 days back) A NID aspirant

              I'm Surbhi Tak & this year I made it successfully to NID.

I am writing something about my journey from a NID aspirant to NID student.

I am a B.Tech Textile Technology & I opted to go for design studies. You might think it as a sudden decision but it was not, Intrinsically I have always wanted to be a student of design. I like creating patterns, adding features to already existing things around me and so on.

                                           It took me a while to reach here & I start my journey, nevertheless it is a journey worth going through because I learnt a lot about designs as well as about myself through the hard work and time I put in.

In a simple language, NID tests 3 things:-
                1. Written exam ( Main exam)
                2. Practical test ( Studio test)
                3. Oral test        ( Interview)

                                           Feel free to contact me to know more about NID examination.

                                           I'm thankful to my family for continued support, but I specially thank Prasanna for continuously motivating me & not losing hope in me.


Surbhi's portfollio

For reference she has permitted to publish few of the works she presented during the interview.


Sample 1 : This is Surbhi’s work showing her skills in understanding lighting and its effects. It essentially shows the how a simple surface appears under different illumination conditions. This work was done by her in Autodesk 3ds Max




Sample 2 : This is a storyboard created by Surbhi. Observe how well she communicates the concept of an educational toy. This toy is designed to feel students more interested in subject of history. She has chosen a national historical figure of Rani Laxmibai for this illustration.


Sample 3 : In this sample of her portfolio, Surbhi is demonstrating her skills over several soft mediums like plasticine (modeling clay), paper and cardboard. Such skills helped her in cracking the NID studio test with ease and also will help her during her course.


Sample 4 : Surbhi uses plasticine (modeling clay) to communicate the concept of a night lamp. This model clearly indicates her dexterity in utilizing the properties of the modeling material to convey a complicated form in a clear manner
Sample 5 : In this sample Surbhi has made a rose using modeling clay. 



Sample 6 : Surbhi made this concept rendering of a wine glass using her Adobe Photoshop skills . She uses her keen skills in understanding light and shade to give her work an artistic effect, while successfully communicating the form. 



Surbhi Tak is joining PGDP in Information & Interface design ( NID, Bangalore). She has done her B.Tech in Textile Technology. She is an expert user of Adobe photoshop, Adobe illustrator, 3ds max,google sketch up and Monkey jam. Besides that she excels at modeling using soft medium (modeling clay, paper, cardboard, etc) In her free time she pursues her hobbies in chess, carom, video games and cycling.

Giridhar MadrasIISc Admissions 2012 Pinned

I have been receiving several queries on admissions to IISc. Unfortunately, I am unable to answer all emails individually. All I can say that the cutoffs for the M.E. program are usually in the 99th percentile. The last year cutoff score in GATE and other national exams for various categories to be called for interview for the Ph.D program is mentioned in the website and use this as a guideline. Emails to me regarding this year cutoffs will not help because cutoffs are decided by the number of students applying.



Update: Interview call letters for the M.Tech/M.Mgt program was posted on the website on March 30. M.E. admission is not by interview and only through GATE score. The admission letters for ME will be posted around April 20 on April 12. There are no waiting lists for ME admission. The admission is based on a ratio of offered to joining based on the experience of the last few years. For the research program, interview letters will be posted by May 12, interviews are from 1 June to 10 June and offers will be posted online around 25 June. For the UG program, the first round of offers will be made by May 15.

FëanorYongy Bongy Bo in India

Yesterday, 12 May, was the bicentenary of the birth of Edward Lear, humorist and artist. I happened rather idly to search for some of his limericks (my son's studying the form at school these days) and learned this fact. I'm not a particular fan of Lear's limericks - the fact that his last lines usually ended the same as his first always felt like a bit of a cop-out - but I was pleased to find out that he had travelled extensively in India, and (in keeping with my current fetish for random art) painted wonderful landscapes of the places he visited.

One of Lear's closest friends was Evelyn Baring, who became the Personal Secretary to the Viceroy, Lord Northbrook with whom also he was closely acquainted. Northbrook invited him to India in 1872 to tour the country and sketch it. Lear was eventually happy to do so, especially since his expenses would be covered by the government. But his initial plans went awry when he was unable to procure a berth to the subcontinent; enraged, he spent time in Corfu and Alexandria and delayed his trip to India till the following year.

He arrived in Bombay on 22 November 1873. He was to spend considerable time criss-crossing the country, sketching and painting furiously. He would visit parts as far apart as the Western Ghats and Kurseong, the deep South and up North. While he was generally a humorous traveller, willing to try any mode of transport, the exigencies of voyaging in India often reduced him to exhaustion ('O! Hateful Indian travel!') but a day spent painting would soon restore his mood.

He travelled on trains, ekkas (two-wheel horse-driven carts) and on dhoolies (covered litters) and jampans (a sedan chair also carried by men), and tonjons (another sedan-chair). He wrote:
The ekka trial was severe, - bumping, - leg cramping and end injuring, - yet better than I expected. At Bahadoorbad we changed to Dhoolies, - the first time of trial, and they are much more pleasant than I expected: - yet, after a time, the row of men, and the shaky movement bothers... The movement of a Jampan is much like that of a Dhooly, - but you have much more room. Only, when the men change the pole from one shoulder t'other, it seems as if they were about to pitch you over into space... Coolies undulating. Much discomfort at first.
He noted the enormous diversity of India - climatic and geographic, cultural and architectural, zoological and botanic. He felt the bitter cold in the hills in the winter, and the severe heat in the plains. In Malabar, he wrote that the 'heat was always great here, stuffy, puffy, muffy.' Amazed by the torrents of the rainy season, his servant asked him, 'Please sir, how many hundred Monsoons are there in India?' In the cold he had had to stand for hours drawing; the rains prevented him from painting at all.

But he ate heartily. 'We lunched in the broad shade of a great Neem tree, exactly like a fine Ash. Excellent leg of mutton, guinea-fowl's eggs, and cheese, besides sherry and water.' He did complain about the spiciness of the food: 'Heavenly potatoes have these people! the best of any out of old England. But the amount of pepper put into the food is hideous, and I have prohibited it henceforth.' He managed to find alcohol in every outpost of his travels, and drank so copiously that he himself was amazed: 'Good evans! if any of my old friends could know how much Beer and Brandy and Sherry this child conshumes, would they recognise me?'

While he was happy to meet Northbrook and Evelyn Barings, he evidently disliked the pompousness of Viceregal life. Likewise, in Calcutta, socialising with the high society was a strain. 'I believe Viceregal life will bore me to death... No rest in Hustlefussabad.' He loved the solitude of the dak bungalows where he preferred to stay during his travels. 'Happiness and quiet appear to me to exist nowhere in India save in Dak Bungalows: - there they certainly do.' In the Himalayas, he wrote: 'the fact of being thus in this house, and well fed, and so comfortable, - in such a locality - a sort of nowhere - on the borders of India and Thibet, - and of being totally unmolested, and with not even bolt on the doors, - seems a semicircle, and is well worth the contemplation of pipkins, pumpkins, poodles and pearly philosophers.'

Lear's Nonsense verses were immensely popular in India. Of course, this is not to say the local population knew any of them. Rather, the colonial kids - living in their bubbles - knew them and even studied them at school. His interaction with Indians appears to have been somewhat limited. He learned a few Hindi and Tamil words. He could ask the way ('Rusta ke hai?') and he was happy to eat 'Bhat' and curry, and in Madras, could say 'Please endewennum?' He expressed regret that he hadn't bothered to learn the 'Lingo' before arriving in India.

He noted the pompous, officious English of the natives: 'Positively, and without the slightest exaggeration, this Railway nuisance of want of punctuality is becoming insufferably unbearable!' He was surprised that the foreign language was spoke widely in India, even in mofussil towns. And he wondered if there was any point in Indian children being taught in a purely English medium to a purely English syllabus. 'Hear upper class read Henry V, and they were examined in Ivanhoe. Is there, or is there not time thrown away in this sort of learning?

He spent 14 months in India and upon return to England even considered returning. But Northbrook resigned as Viceroy in 1876, and that put paid to any such thoughts Lear had had.

T Vasu BabuManchanbele Revisited



Went to Manchanbele Dam/Reservoir today. Later realized Big Banyan tree is also on the way and explored that too. I have been to these places before during IISc Populaire Savandurga 100. But at that time everything was in hurry as we have to complete the trip within specific deadline.

Today's experience : Both are great places. I loved the Big Banyan Tree, some people like trees, some like Animals, I am a tree guy so that was obvious. It was perfectly cool (natural AC) under the tree, I even took a nap after having my Lunch, that was great :-) But it wasn't easy, there are many monkeys around, they snatch stuff, particularly if they have weak opponent. They were planning to target my backpack when I was in sleep, but I woke up once I hear their movement nearby.

Ride Report - around 100km, approx 8 hrs. Started aroung 6:45 AM came back around 3.00 pm. I have some really nice videos but don't have patience to upload them on youtube and put the link :-) will do that some other time.

Manchanbele Dam, I met some other bikers there

If you have the tring-tring kind of bell on your bicycle, have you ever noticed that the place where you press it with your thumb has something like "LIFExx" written on it (xx stands for a two-digit number). On the photo above it's "LIFE99" and on my own humble Hercules Thriller it's "LIFE72". What does it mean? Any answers?

Raamesh Gowri RaghavanPoems in the sand

There are poems in the beach sand,
Eroding in the wind and waves,
Left behind there by ephemeral imaginations,
That concern neither the crabs sidling over them,
Nor the rich red sunsets,
Nor the clouds hanging low in the romantic depression
That only poets bother with,
Nor the sandpipers skimming over the waves;

But they will never be completed,
Foaming away into the sea,
The poet's illusions drained away,
Into the eternal indifference that is the universe.

Deepak MalaniThe Economics of Sharing

The Economics of Sharing
How your casual social interaction generates revenue for companies

The recent announcement of acquisitions of Instagram, by Facebook and Slideshare by LinkedIn indicate a growing economic value of sharing content or information. Instagram lets people freely share and tag any photographs with the world. This was a value proposition for facebook since a large chunk of social interaction among its users is photovisual content. Slideshare on the other hand lets people share presentation content, just as youtube does for videos. LinkedIn, designed as a professional networking platform structures content and discussions among its users. Its acquisition of Slideshare helps add significant knowledge resources to its users.

Now the money involved in these internet based companies reveal a rocketing image. Facebook bought Instagram for 1 billion dollars, the company having a core team of 12 members only and was founded in 2010. In less than two years, it has more than 50 million users, and a hundreds of millions of shared photographs. While Slideshare, founded in 2006, was bought for $119 million, it has 16 million users and close to 10 million slides.

How do these companies generate such large revenues? Online advertisements reach out to an uncomparably large and wide audience. And there are smart computer scientists designing intelligent software algorithms to bring appropriate ad to the potential customers. So if you are discussing a holiday with your friends, pop you see an advertisement from a tour agency offering you tailor made plans. Or if you like a particular jazz album, you get ads of music companies offering you discounted DVDs or rentals. Where else can companies find a medium to target a million users a day checking out their webstores! The concept of freemium and group-deals are offsprings of this revolutionary market platform. Companies and brands even get real-time customer feedback through twitter trends, or public response to social media campaigns. Users often come across sponsored ads on certified online course, training programmes, and even HR folks find it reliable to recruit through professional networks.

There seems to be a great economic value today in sharing content or plain information. And then if developers can create a platform allowing users to share, there are tons of e-advertising revenue models. This market has received a power booster with affordable and always-on mobile connectivity through apps ecosystem. So next time, you get a discount on a microwave, you can guess that your spouse has liked your neighbour’s status update on an oven cooked dish, with a photo of spicy roasted chicken!

Pradeesha AshokSleeping Murder by Agatha Christie

A long stressful week and I know I have to pick up a mystery from Christie in the weekend.

Gwenda, a newly married girl, is searching for a house  to settle down in England. She is new to England and finally finds her perfect home in an English countryside. Everything was going on well till she understands that she seems to know much more about the house than she should know. She almost believes that she is mad when she remembers seeing a dead body in the hall. It is now that Miss Jane Marple comes to her rescue. She helps Gwenda to realize that she had actually lived in the house as a small child and that is how she knows about the house so well. And the next important question is : Was a murder  really committed in the house?. Miss Marple tries to discourage them from digging into the "sleeping murder" but Gwenda and her husband are very enthusiastic about it. Unknowingly, they were inviting danger to their doorstep. But there always is Miss Marple to the help.

This is one of my favourite Hercule Poirot mysteries and there is no one like Christie who can handle murder-in-the-past plots. Sleeping Murder just establishes her as The Queen of Crime beyond doubt.

A good mystery from Christie, 3 out of 5.

Trivia : This is the last Miss Marple mystery, published posthumously in 1976.

FëanorToot That Flute

The boy's been learning the fife for several months now. It's a bit of an uphill/downhill situation with him. Uphill struggle to get him to practise, and then it all goes downhill during the holidays when he doesn't even look at the instrument. No, no, I jest. He has learned the B, A, G notes rather well, and even if he has a bit of a problem distinguishing a quaver from a semitone (is there a difference? I don't know), he does manage quite well to follow the score.

It is the usual condescension towards the recorder that prompted us to put him up for flute. Who plays recorder seriously? was the question topmost on the lips of the mums in school. The flute, on the other hand, that's an instrument of poise, elegance and character.

Because of a bit of miscommunication with the boy's flute teacher before he started, we got into a three month rental of a flute, which, when she saw it, turned out to be the wrong instrument for learning, and 'anyway, it is not very good.' She said that the fife is the beginner's instrument and is cheap, and - were we to purchase it from a little shop in East Croydon - would get a teaching book with it.

The intention was for the boy to have weekly 1/2 hour-long lessons at school, and practise at home about 10 minutes a day. The result was a bit more uneven - some days went without practise, and other days he'd manfully struggle for half an hour at a time. 

His little fingers had trouble covering the hole, and for months he wasn't even able to consistently produce the correct sounds. Embouchure, we were told, it's all in the embouchure. 

When he got a bit better, he was asked to write a line or two of music to practise. His first composition was a bit confused - as I said, he had little idea about the beats and lengths of each note. Having just that day learned about 'slurs', he liberally applied them to his piece. He forgot to give it a title, and when prompted by the teacher, announced that it would be named 'The Lonely World of Emma'. It did sound a bit melancholy. We are still not sure where the title came from, and he is cagey about his inspiration.

Recently, he has moved onto the D and E notes, and these are giving him particular trouble. Playing the fife is about dexterity in the finger movement and their correct positioning atop the holes, and he is flummoxed by the switch from E to G, say, where the big fingers of the right hand are lifted from the instrument and only the left hand is used.

Now the teacher wants him to progress to the apprentice flute. £125 for this. We were a bit stumped by the cost. How long would he continue on this instrument before moving on to the next level? If it was a matter of months, perhaps we could rent the thing. But if he could use it for a year or two, we'd need to buy it. In the event, it turned out that renting it for a few months cost as much as buying it outright, so I trudged over in the rain and cold and dreariness to Croydon a few days ago and procured it.

Immediately the boy wanted to play it. This flute doesn't appear to have any holes, only keys. He was unable to elicit any sounds from it. He'll have to retrain his embouchure and all that starting next week. Meanwhile, he has several days' worth of work on the fife left.

On Friday were the woodwind finals of the BBC Young Musician of the Year 2012 series. To our surprise, a recorder featured in the competition category finals. So much for it not being a serious instrument. Take that, supercilious mums on the school run. There was also a flute, a clarinet, a bassoon and a saxophone. Seeing the recorder (played by the youngest competitor - Charlotte Barbour-Condini - all of fifteen years old), the boy sniffed with disgust. He was in support of Luke O'Toole, the flautist. 'I am a fan of Luke,' he admitted to his mother before he went to bed.

When Charlotte played, he kept sniffing. 'When is Charlotte going to stop?' he asked. 'The recorder is boring.'

'Be nice,' I said.

'Oh yeah, it is a fine thing,' he said. 'My teacher teaches the recorder. I wish I could learn the recorder.'

A couple of minutes later, he said, 'Boring. How long can we just keep listening to music?'

Then he said, 'Why are her eyes closed?'

He stayed up till Luke's turn to play the flute. 

'I am very good at the flute,' he said. 

Then he went to bed. This morning, almost the first thing he wanted to know was whether Luke had won.

I checked the programme on BBC iPlayer. When he saw Charlotte Barbour-Condini being interviewed just before the winner was announced, he said, 'Charlotte, Charlotte, Charlotte, stupid Charlotte.'

'Hey,' I said.

'Actually, she is nice. Did Luke win?'

Luke did not win. Charlotte won. What an achievement! She was smiling through her tears.

'Look,' said the boy. 'She is grinning from ear to ear.'

Rahul SiddharthanOpen letter to Dr V M Katoch

I sent the following to Dr Katoch on Monday, May 7, 2012. I haven’t received an acknowledgement.
UPDATE May 12, 2012: Please also see the petition from Nilanjan’s wife.


Dear Dr Katoch,

I am writing to you as the chairman of the Board of Governors at NIPER, Mohali. As you are aware, Dr Nilanjan Roy, who has raised concerns about financial dealings at NIPER, was dismissed from the institute recently, by the officiating director.

I know Dr Roy slightly but I do not want to judge the case. I believe that the case should be investigated impartially and thoroughly by an independent committee, and Dr Roy should be kept in his post pending such an investigation. As chairman, I urge you to take immediate steps in this direction, before further damage is caused to NIPER and to Indian science in general.

My reasons for this are the following.

1. As you are aware, NIPER has previously dismissed a scientist, Dr Animesh Roy, who had alleged misconduct on the part of another senior NIPER scientist. Reportedly [1] an inquiry committee set up by NIPER’s board found, back in 2009, that the allegations made by Dr Roy were true and he had been punished for whistle-blowing. Nevertheless, he was not re-appointed until 2011. This is a black mark against NIPER and should under no circumstance be repeated. Dr Nilanjan Roy should therefore be allowed to continue at NIPER until an inquiry by impartial and eminent scientists, unaffiliated with NIPER, is completed.

2. It is particularly a matter of concern that an officiating director should take such a step against a scientist without holding an impartial enquiry. Media reports suggest that Dr Nilanjan Roy has already appealed to you and, pending your decision, he cannot be dismissed. However, he tells me that he has already been asked to vacate the institute and his residence.

3. It appears that the people who made false charges against Dr Animesh Roy were never punished and continue to have power in NIPER. This is an extremely distressing state of affairs.

I have already made a blog posting on this affair [2]. I very much hope that, if I make a new post on this subject, it will be with some good news.

I am copying Dr Nilanjan Roy and Dr Animesh Roy on this mail.

Looking forward to your urgent reply,

With best regards

Rahul Siddharthan

UPDATE 10/5/2012: Reading the comments, it is fascinating to me how those who know Nilanjan and are defending him are doing so with their real names, while those who are attacking him are hiding behind pseudonyms.


Giridhar MadrasWork day

There is an interesting discussion on the length of work day, especially in academics. I think many academicians look only for productivity and I think advisors only look at the work ethic of the student if the student was being non--productive for a few years. The time that is spent on the work bench is probably less important than the time spent required in thinking about the project.

For the faculty, the key is to plan well and not spend lots of time on long coffee breaks and mostly useless meetings. Of course, in IISc parlance, if the faculty is called hard working, it normally means that (s)he is not very bright !

Chetana BaligaBlank Spaces


A blank space – indeed how does one begin to describe a blank space? On the very face of it, the phrase appears to be a tautology, with ‘space’ itself meaning ‘a vast, unoccupied area’. As darkness is defined by the absence of light, the blank space can be defined by the absence of substance. But, on a second thought, one sees that a blank space holds innumerable possibilities for interpretation.
To a painter, it is an empty canvas, pregnant with myriad possible paintings to be made. To a teacher it is an innocent child’s mind, ready to be taught and eager to learn. A sculptor would see it as a beautiful piece of stone, waiting to be carved into his next masterpiece. It would remind the farmer of a land to be cultivated; and the builder, of a land that can be developed into a luxurious and profitable layout. A dancer would liken it to an open stage and a writer, to an unwritten page. The lover would see in it, a place where beautiful day dreams can be woven.
To the thinker, it is the absence of cluttering. The yogi says it is the beautiful calmness and peace of mind; while to the spiritual, it is Nothingness, the point at which one sublimes and merges with the Supreme.
A nature activist sees a blank space as a place of extensive deforestation. To the depressed it brings pictures of bleakness, while the psychiatrist would call it a representation of Alzheimer’s disease. To the destitute, it is home.
The beauty of the blank space lies in the eyes of the beholder – unadulterated and pure, or, barren and devoid of life. A pristine landscape waiting to be explored or a frightening ruin that drives away even the whiff of joy. A blank space is, thus, an externalization of our own mind. Our thoughts are what we see in it. When we calm our mind and drive out disturbing thoughts, it becomes the blank space that can be moulded into countless possibilities.

Prasanna GadkariDifference between story board and comic strip



This post has been inspired by question asked by chetanyadav, here : "How to prepare for CEED":

A story board and comic strip has following characteristic differences:

1. A story board is used to convey information, while comic strip is mainly humorous or just entertaining

2. A story board often is not published anywhere, while a comic strip is drawn to be published in newspaper or magazines

3. A story board is an intermediate, and often compulsory step in animation and film making, while a comic strip is an end product in itself

4. A story board is often drawn with additional information like camera angle, transition to next frame, etc. while a comic strip does not contain such information

5. A story board focuses mainly on action and does not necessarily contain dialogs that the actors say, while a comic stri generally contains speech bubbles.

6. A story board may not be always drawn in fixed space, while comic strip’s length is identified by where it is published.

Rahul SiddharthanCrickets, temperature and sound

Here’s some insight into what controls the chirping sounds that crickets make. I’ve been intending to talk about this paper, which is interesting to me since I’ve been interested in bioacoustics for a while (though, in my case, more in perception than in production of sound). But Natasha Mhatre, the first (and corresponding) author, has saved me the time by summarising it very nicely herself, here. Go and read to learn about how size correlates with frequency of sound, in a variety of creatures, and how it breaks down in tree crickets (whose frequency changes with temperature). The original paper is here. Additional coverage is here.


Sujit Kumar ChakrabartiOne Thing Good About Being a Celebrity

Came across two instances of the power of being a celebrity yesterday.

First. Aamir Khan's Satyamev Jayate on Star Plus which is to be aired every Sunday at 11 AM starting yesterday. The programme deals with social issues plagueing India. The first episode yesterday was about female foeticide. It presented data and analysis pertaining to the issue bringing forth its scale, nature and causes. It introduced some victims and some people who have been doing something to solve the problem. It ended with a couple of action points identified for the makers of the programme as well as the viewers. Thoroughly researched. Aamir Khan has spent nearly a decade or more to build a special philanthropic image for himself, from doing movies like Rang De Basanti, Taare Zameen Par, 3 Idiots, Mangal Pande, and even Dil Chahta Hai. Also campaigns like Atithi Devo Bhava. And in this programme, he brings its force together to hit the viewer's consciousness really hard. Commendable effort!

I hope to be treated with enlightening and moving accounts on many more social issues in the coming weeks. It will be an hour of weekly respite for the TV and its viewers from unending series of mindless soaps, abusive and phony reality shows, sensationalist news coverage, sexualised sports. While this programme is on air, I will give up my abstinence from TV. It's like we are back to our good old Doordarshan days when the ill-endowed documentaries used to be rich with one thing: sincerity.

My wishlist of issues for Satyamev Jayate:
  1. Environment
  2. Education
  3. Corruption
  4. Analysis of India Shining

Second. I came across this other one while flipping through the channels during a commercial break during the above programme. I don't remember which channel. Nor what programme. But there was Salman Khan talking to a phenomenally obese 18 year old girl giving her advices about being healthy and stuff. Not so impactfully presented, nor dealing with an 'apparently' social issue. But I feel that it's an equally widespread problem: this problem of unhealthy lifestyle. The cost of bad health due to lifestyle issues must be second to none on the society.

These celebrities aren't saying something no one else has said. Just that their position as celebrities gives them this unique chance to be listened to and taken seriously. I am happy they are finding it right to use their status for saying something really meaningful.

PS: Heard it that Aamir Khan is getting 3 crores for each episode of Satyamev Jayate. If he continues doing the kind of job he did in the first episode, I think he deserves every paisa of it.

IISc Hockey ClubIPLH 2012: IISc Premier League Hockey Begins

Match Review #1: VII Kissan Vs Hunting Hawks : 2-1
VII Kissan Scorers: Arvind and Vikram Rathi
Hunting Hawks Scorer: Priyank Goel

IISc Hockey Club Logo

IISc Hockey Club Logo

VII Kissan took an early lead through Arvind, who deflected the ball into nets in 5th Minute of the game. Then Hunting Hawks attacked relentlessly on VII Kissan’s D, which resulted in a PC for the Hawks in the ending moments of first half. Experienced Hawks campaigner Priyank Goel leveled the score through their first PC, which was completed after the lemon break hooter.

As both teams stood almost equal chances in first half, and went into lemon break with tied score, tried few different things, but Kissan Vikram Rathi outsmarted Hawks defense with his speed and control on ball and scored the winning goal.

Both the teams played some nice hockey, but Kissans missed lots of easy chances early in the game, while dangerous looking Hawks failed to enter the danger zone of Kissan guarded by Manoj Mahala and Ambemdkar Dukkupati with the help of Pradeep Khatri and Vaibhav Goel. Harish Varma was bit off the mark in mid-field, but well supported by Vikram Rathi, who covered a lot of ground. Hawks had their own time in patches, and kept pressing Kissans into defensive mood. Hawks’ Captain Shabir was not sharp in his moves, as usually he is. Priyank Goel was undoubtedly best man on field from Hawks. Nirmal Iyer also created a lot of problem for Kissan defenders. Hawks certainly missed the experience in their defense due to absence of Abhshek Bhat.

Match Review #2:  Titans X Vs Spartans : 2-1
Titans X Scorer: Senthil (2 Goals)
Spartans Scorer: Snehal

Spartans failed to overcome the experience of Titans X’s big guns including Kumar P, Santosh Sathe, SR Bharath and Raghavan V. Spartans’ Pradeep Moise, Jimreeves David M and experienced Vijayraghavan put up a brave fight. But the heroic save by Titan Kumar P on Vijayraghavan’s push on the target snatched the match from  Spartans.

The contributions from the youngsters, Abhinav, Kishore, Arvind, Manohar, Susanth, Shashank, Pravir, Swapnil, Snehal, Pradeep, Nikhil, etc. can not be ignored in the games played today. Despite their first IPLH, their gave an energetic and matured performance.

With the inputs from Senthil and Mahesh K.

Natasha MhatreWord beasts: tree crickets break the rules, sort of.


This time its my own work. We just published a paper that I think is important for a couple of reasons. I'll outline the main one here. I've not gone into this detail in any of the popular science articles I've interviewed for, simply because this is a subtle point. (And also because it got lost in trying to explain the work, I'm not practiced at this interviewing thing). But this is my blog, so I can tell you and take the long route, consider this your fair warning! This is not an explanation of the paper, but of why its interesting.

There are very few laws in biology. By laws I mean rules that hold far and wide across a huge phylogenetic range of organisms. Biology is about variation, making oneself distinct, occupying a new niche. So, in the complicated messy world of biology,  it's quite rare and hence, comforting to have a 'law'. Often when such laws exist, they are rooted in physics. For instance, the law that relates thermoregulation capacity to body mass. Since larger animals have a lower surface to volume ratio, they retain heat well and lose it poorly. And vice versa for small animals, loose heat easily and retain it with difficulty. As you can see, this law is very rooted in the physicality of the body. You may even say it is rooted at an even more fundamental level, in geometry itself.

The law that relates to our paper is quite similar. In animals that communicate using sound, the dominant frequency of the sound they produce is correlated to their body size. Neville Fletcher, who has written text-books in the field of acoustics and bioacoustics, calls it a rule that holds from insects to elephants. And he is right; it does, by and large. There are simple physical reasons for this behaviour. They relate mainly to the efficiency of sound production at frequencies appropriate to the organisms size and to the mechanisms of sound production. For instance, insects use resonators as an important element in their sound production mechanism. A large resonator, therefore, leads pretty much deterministically to a lower frequency.

Now, many bioacousticians take this a step further and suggest that size relates to frequency not just across species but also within species. This is not really a large logical step. The reasons why this relationship would hold are the same as for the across species relationship.

The next step that researchers in the field have argued for is somewhat more problematic. They assume (and also test, sometimes) that because this relationship exists, information about size exists and can be percieved in the sounds an animal makes. There is some tentative evidence and a strong belief that size is important to mate choice and choosy females prefer larger males who are somehow 'better' in evolutionary terms. Taking the step, however, it turns out is more complicated; there are a few assumptions that have to hold to make this 'information transfer' and consequent 'choice' possible.

The first assumption is about reciever psychology. There is a presumption that a reciever can make frequency discriminations that are as fine as the spectrum analysis techniques used to study the sounds in the first place. If the change in size associated change in frequency within a species is smaller than the frequency resolution of the listening party, the question of telling the size of a caller is moot.

The second assumption, which we are concerned with, relates to the next level of variation, the within individual variation. The first level of variation is across species, then within species and finally within individual variation. If within individual variation in frequency is higher than within species variation, then information about size is obliterated and no meaningful 'choice' is possible.

 Here's where the crickets come in. The way crickets sing is quite special. Not only do they use resonance to produce song, they also use the resonance to tightly control the song frequency using something called an escapement mechanism*. The idea runs: therefore, within individual variation will always be lower than within species variation and the information must exist in the song. And not just for crickets; this relation is often thought to hold for insects in general since many of them use resonance as a sound production mechanism.

Not so, say the tree crickets, whose frequency changes with ambient temperature. As a direct result of this property, an individual tree cricket's frequency variation is as large as that of the whole species and the train of logic crumbles because an assumption is not met. Remember the law has not been violated, not strictly, the range of frequencies each individual insect will produce will still depend on his size. But since he can call from anywhere within that range, you can't figure out his size from hearing him at any given time. The information that falls out of the 'law' is gone.

We found that these insects, tree crickets, use resonance for song production as well, and have the same singing mechanisms as other crickets. But these mechanisms fail to control song frequency. So we asked, well, how do they do it? What does it take to break this link down and remove 'information' about body size from song frequency? How hard a transition is this? It turns out, its really simple. All you have to do is sing with longer wings. No fancy non-linear mechanics, no stochasticity in the relation between body size and resonator size, no super temperature sensitive materials, nothing special. Just longer wings. Geometry trumps everything.

And that is why its an interesting result. It doesn't take a lot to break down a train of logic which everyone thought derived from a profound biological 'law'. It takes a relatively small change in geometry to undo a laws effect. That is how easy it is to tweak biological systems. And that ease is one of the sources of the huge diversity you see out there.

Sivaguruan acrophobic’s attempt

recently, i had posted a picture on my Facebook page.

while this got many likes and some comments of appreciation, there were also ones of

- doubt

- disbelief

etc.

this post is to go behind the scenes and tell it all!

not so much to garner appreciation or admiration [Smile] but more to share the bigger picture behind this picture ..

it all started when some colleagues and business partners stopped briefly on a road trip,

at the Columbia river bank — at Ginkgo Petrified Forest State Park.WP_000128

to reach this spot, we had to cross snow clad mountains : WP_000123

clear snow WP_000124, one handful at a time!

and reach the land of the wanapums WP_000129.

and cross a rocky and dry environment, WP_000130

while they are almost extinct now – per the sign there, the beauty of the location still hasn’t vanished.

the river was almost a gorge WP_000127IMG_0404

 

there was this protective wall at places IMG_0405

and no protection at others IMG_0411

i chose to venture to the other side of the wall!

while the effect in the picture IMG_0420 was a combination of
camera angle and the subject’s position, it was, i should admit, a safe spot with reasonable foot room.

but, for an acrophobic, this was something!

FëanorA Fight

There's a lovely site called Oldmos.ru where people have been posting old photographs of Moscow - their families, cityscapes, histories, memories. An occasional browse through it reveals hidden depths, heart-tugging tales, a sense of wonder. I came across this photograph of a bunch of kids fighting in the snow. 

Children fighting in the snow. c. 1912.
At first glance it might appear violent, sadistic even. But a commentator reveals that all these kids are family - brothers and cousins. They are posing for the camera. What do they know of their eventual fate?

Two of the kids are the sons of the chief of prisons in the Department of the Interior. The fellow with the broom is George Ksavelevich Velichko. He will become a railwayman, and will live out his life in Irkutsk. He will die in 1986, leaving behind five children and 17 grandchildren. The fellow with the snowball is Samuel Ksavelevich Velichko. He will leave for India in 1921, then to Bari in Italy. He will become a cargo man, a newsman, and then will marry and become a proprietor of a cafe. He will reestablish connections with his relatives who remained in the USSR in 1990 through the Red Cross. 

The chap with his hands apart is Viktor Viktorovich Velichko, son of an architect. He will graduate from Saratov University and become a chemist. He will perish in 1944, before being able to set up a family. The fellow with the log is Pavel Kirillovich Velichko, son of an army man. He will graduate from the MIIT, and become a father of three sons, and serve in the armed forces during World War II. He will drown in the Oka river in 1963. 

The chap on the ground is Johan-Anton Stanislavovich Velichko. He will emigrate in 1919 to Poland, and serve in the border guard. He will be captured by the Red Army in 1939. Two years later, he will be executed in Tver. His great-grandson will post the picture and reveal the story.

Ganesh H SThe Fire!

This is yet another post on my time spent during my engineering days, unlike my previous post I won't be cribbing much in this one. This post is about what kept me running.

It was 17th May 2002, I was in the second semester of my engineering. My branch of engineering was Telecommunication. And it was "World Telecommunication Day". I came to know that there was some function arranged by my seniors of my branch. I went to my department to check it out. (In the first year we had classes in the college administration block hence we were fairly disconnected from our department ). I was pretty excited to know that the function was some kind of a department festival, and the celebration was mostly in terms of having contests, technical paper presentation and exhibition of engineering stuff done by students of our college. I didn't take part in anything, I just observed the events. It was completely organized by my seniors, while the professors and other staff members of the department were very much there to witness the proceedings. I could sense the excitement in the crowd. I felt like being part of a very fresh and super interactive club. I felt awesome!

The first year of my engineering was fairly insignificant and less eventful. I hardly have anything to say about it, where as if you ask me about my second year I should have so much to talk about. The subjects in my second year were very specific to my branch of engineering. Since my dad was also from similar background he had many books related to my subjects. They were very quality books mostly by foreign authors (rather from international book publishers). Turning the pages from those books made me feel like I should some day be equipped with all the knowledge to create stuff, solve problems in engineering and do advancement in technology. Seeing my enthusiasm, dad bought me some more books which were useful for my studies and also for the long term reference. Many of my classmates were comfortable reading the books written by the local authors which were tailor made for the syllabus. In my opinion they were bad books. They helped a student to get good marks but the authors of the book didn't communicate the engineering ideas quite well, though I guess there were few exceptions. While I took my own time to understand the concepts from the books I referred, I was also losing out on the race of scoring marks. Since I wasn't answerable to anyone, I didn't care much about scoring high.

During my third semester and fourth semester holidays I happen to spend most of my time in a state-of-the-art electronics Lab which was located some where in the industrial hub of Bangalore(in Peenya). Dad knew a person who was a trainer in that lab who made arrangements for me and my friends to use the lab for doing any electronics circuits we wished to do. The lab was pretty much a paradise for an electronics geek if you ask me. Some of my friends who came with me were super excited about trying out all the circuits we learnt in theory but never got a chance to do the same in our collage laboratory due to limited time and components. The place was pretty far from my home and almost took two hours to reach there, however the bus journey wasn't less interesting as I had lots of discussions with my friends regarding the circuits we were about to try and other things pertaining to electronics design. The time spent in that lab was so influential that I convinced my dad to setup an electronics lab on top our house when I was the third year. Incidentally I currently work in the same lab.

Some day in the mid of fourth semester, our third year seniors came over to our class to do an announcement. It was about celebrating "The World Telecommunication Day", they also mentioned that unlike previous year, this time they were planning to have the fest for two days and at an inter-college level. They were accompanied by a lecturer who wanted to assist in organizing. I was super thrilled to hear that announcement. They wanted volunteers for the fest from our class, but unfortunately none of my class mates including me raised our hands. I was waiting for some one to raise their hands. Looking at the nil response, our seniors were forced to pick few people whom they already knew in our class to volunteer. I felt like killing myself when they left the room. After the class I went to that lecturer's room and told him that I wished to volunteer. Looking at my enthusiasm, that lecturer immediately took me to a member of the organizing committee, a senior, and told her to include me. She was very glad that I wanted to volunteer. She was part of the creative team that was mostly into stage decoration and advertisement of the fest - exactly what I was interested in.

During the fest preparation I became friends with many of my seniors, especially the third year folks(The final year students were mostly in the verge of leaving the college hence weren't visible in the college much). I could infer that they were very inclusive and kind towards me. When I told them that I had an idea for the backdrop for the stage they supported my idea with great conviction. I must say that it was a fantastic experience working with my class mates and my seniors in creating that backdrop. I also did lots of posters for the fest with them. All the skills that I had acquired in painting and craft during my childhood came in very handy while doing the posters and the backdrop. I gained great attention from all, including the teaching staff. I felt damn good, I felt like I was building my own identity.       

When I was in the third year it became our responsibility to take the lead in organizing the fest. I did no injustice to it. This time I was more confident and as a matter of fact I was a bit aggressive as well. We started off much early. We did posters that were just like those TV promotions saying "coming soon" types. Two of my class mates were equally excited in doing the posters for the fest. We had great fun in doing them. I requested more funds for art materials which helped us literally pant the campus walls with posters and banners. I had this bunch of juniors who were ready to do anything and everything for the fest. I still remember running around the city market with them to get thermocol sheets, card-boards, paints and many other things for the fest. Like my seniors, I did encourage my juniors, especially this guy called RP. He was super creative. We did lots of posters together and almost all were his ideas. We also made a back drop that was partially lit by LED lights - which were powered by our laboratory power supplies and made with bunch of electronic components from the lab. All in all we had kick-ass fun before the fest and during the fest. Well, after the fest I was pretty much the guy I always wanted to be :)

I was in the final stages of my final year engineering project when the fest was organized by my juniors from the third year and the second year. I could some how make some time to attend the fest. The same bunch of juniors who worked with me were the most active members of the organizing committee. They told me quite many stories that happened while arranging the fest and also introduced me to some of the second year folks. The fest was more successful than any other year. I could see so many students from various colleges coming up with self-designed electronics gadgets for the project display, high-funda topics on communication for the paper presentation and many participating in contest like dumb charades, quiz, JAM, gaming etc. I could see the same excitement that I saw when I was in the first year. At that moment I felt I would miss my college like hell. Though I hated the education system, I could never deny that it was the same system that gave me the chance to do some thing worth while, something meaningful - an experience that I would remember forever.

Giridhar MadrasGM closes

GM closes its R&D lab in Bangalore. Approximately 90 researchers, including a few of these who obtained their doctorate in chemical engineering in IISc, were laid off.

Rahul SiddharthanBlogging, social networking, and me

I started a blog some years ago, on blogspot, mainly to talk about non-academic things.

As time went by, my blog started to talk more and more about academic/scientific matters, and I grew more and more frustrated with some shortcomings of blogspot. So I moved to wordpress and refocussed the blog.

Meanwhile, I also joined facebook, which was a useful way to share amusing links, and also to reconnect with old friends.

But, recently, I have found Google+ to be a particularly nice combination of all these features: you can share stuff, from trivial to profound; you can participate in discussions with people you don’t know; and you can follow lots of interesting conversations. The mainstream media has tended to dismiss G+ as a “ghost town”, but it has also attracted many high-profile evangelists like Guy Kawasaki and Tim O’Reilly. And as for friends, though it’s momentarily nice to say “hi” to people on FB whom I haven’t encountered for years, in the end it’s the connections in real life who matter more to me.

I never joined Twitter, and now never plan to.

Today I decided to drop off Facebook. I will post mainly academic stuff on this blog (but sometimes cross-link on Google+), and mainly non-academic original content on G+ (and sometimes cross-link it here). My G+ posts will be public. Feel free to follow and comment.

To kick it off, here’s one on Android devices.


FëanorVine

A little over a year ago, Amazon UK invited me to join their Vine programme. They said it was because people found my occasional review at the website useful. It is possible that is the reason: I have 128 reviews and 254 out of 352 readers liked them. (The remaining 98 are just nasty folks.) For some of the giants of the Amazon review scene, these would be pitiable numbers. Luckily I do not aim for giant-hood. I'm quite content being a pygmy.

There are benefits to Vine membership. Occasionally a nice item does drop into my sweaty palm. One recent example is the as-yet unreleased exploration of London by David Gentleman. I got London, You're Beautiful: An Artist's Year yesterday and I spent a couple of hours going over its pages. It is quite lovely. Here's what I submitted in review:
David Gentleman has lived on the same street in North London for more than fifty years and in the same house for slightly less, and yet for much of his life his artistic eye has been cast elsewhere. Last year he decided to take a look at his hometown with a fresh perspective, that of a flaneur, and he provides a look at much of the capital's gems as seen from street level. With deft brush-strokes and quick pencil work and a lovely palette of watercolours, he has depicted large parts of the city with love and keen observation. From January to December, he explores the moods of London. Some boroughs he revisits - you will see Camden and Hampstead over and over again. Other parts are captured in the moment of their finery. The City, especially, gains much from his interpretation - take a look at the sequence of angular buildings on Great Victoria Street and Poultry. He visits the theatre and street markets, he observes London from the heights of its hills, and he sees the new vertical city (the Heron Tower, Gherkin, Canary Wharf, Shard) in a new light. Interspersed throughout is his quiet commentary, witty and gentle. I suspect a coffee table format in large size would have been much more striking for some of the more elaborate pieces in the book, but many of his sketches are like miniatures, sharp and concentrated, and so revelatory in small size. This is a book to sample and savour.
See? I liked it.

It's not just books that arrive on my doorstep from Amazon. I have also received a pair of headphones. The electronic items usually are in big demand. There are people who are very likely sitting up in front of their computers at 8pm every third Thursday of a month, constantly refreshing their Vine pages, just to see what freebie electronic goodies are available. (Once, at 9pm on a Vine day, I happened to look at the website: there had been a fancy super zoom digital camera on offer. I'm sure the last of those had vanished at 8:00:04.)

As long as you review at 80% of the items you have ordered, you can choose two more every third Thursday, and another two the following week. Having started in March last year, I should have had nearly fifty items in my possession by now.  I chose 18 items.

Choosy and ungreedy, that's me.


Rahul SiddharthanGetting fired for whistle-blowing

Some time ago, the National Institute for Pharmaceutical Education and Research, Chandigarh, fired one of its scientists, Dr Animesh Roy, who had made allegations of unethical practices against another senior scientist at that institute. G S Mudur’s article from 2009 goes into details. Quote:

An inquiry panel set up by Niper’s board of governors has now said the institute punished Roy for blowing the whistle on unethical research practices by the head of its pharmaceutical technology department, Uttam Chand Banerjee.

Two independent scientists asked by the panel to evaluate Roy’s performance have given him high grades. The panel has called on the institute to reappoint Roy and initiate action against Banerjee….

The institute’s dean, Saranjit Singh, told the panel that Roy had “hurt our egos” and it did not matter whether he was a good scientist or not, according to the panel’s report. Singh told the panel Roy could be accommodated at any other Niper, but if he were reinstated at Chandigarh, Singh and three others would “resign under protest”.

Privately, I have heard from various sources, in agreement with the report above, that there was substance to Roy’s allegations and no substance to the charges against him. But he was never reinstated he was reinstated only in September, 2011.

More recently, I heard from another NIPER scientist, Dr Nilanjan Roy, who was also fired, this time for alleging financial irregularities — specifically, that huge amounts of funds were either unused or diverted for other purposes. This case too has hit the media. The Deccan Herald covers it here; a TV report from Times Now is here.

Earlier, the allegations of corruption were covered in The Mail Online, which reported that the ministry of chemicals and fertilisers has asked the NIPER board for an explanation. The Mail Today reports that the government is facing criticism in Parliament and has asked the Planning Commission to undertake a “comprehensive evaluation of the performance of NIPER”.

A blog dedicated to this case has been up here for a while.

I have met Nilanjan once and corresponded with him a bit now and then. I believe he is an honest man who acted out of concern for his institution. I hope that the chairman of NIPER’s board, Dr V M Katoch, takes a personal interest in ascertaining the facts of this case, and does not wait for a court order directing him to respond. If cases like this are left to the politicians to worry about, it does not speak well for Indian science.



UPDATE 5/5/2012: I corrected the claim that Dr Animesh Roy was never reinstated: he was, but over two years after the Telegraph report above appeared.


Prasanna GadkariExperience about IISc interview shared by Vinayak


vinayak has left a new comment on your post "CEED Candidates, Dont give up hope!":

thanks Prasanna

the DAT conducted at IISc is very different to that of IDC. IDC had questions more or less same as that of CEED; but IISc had an important part carrying the engineering questions (most of which came from fluid mechanics). so anyone aspiring for iisc should once go through their technical stuffs!!!! well, i hardly found solutions of anyone of them :) 

and what i think is that there is more emphasis on interviews !!

i had interview for around half an hour.. they had 5 panel members.. they started with a discussion about touch screen; it's uses and its future... as my background is electrical, they asked some technical question!! and some random questions checking my communication skill!! some general awareness questions etc...

and Prasanna, i didnt forget to mention about your blog too!! they were very happy to know about it.


Dear vinayak,
Thank you so much for sharing your experience with us! It will surely help aspirants!! Wishing you a bright future ahead!

G S JavedEinstein's Marriage and His Research - Part I

After reading a small entry from a fellow Ph.D student, he too in his Second Year, about Albert Einstein in his graduate days, it brought out an amused laugh.

Read Between the lines My friends!!

It says, it was his 2nd year of marriage.

           He must be totally freaked out by his wife that he though of the presence of atom, How could that even happen ? .
.
.
.

You know why? Because she was making him go around her again and again. He would have thought "This is very interesting. She is like a nucleus which keeps me attracted towards her, and also make me run around her. Thank you Honey.
(I get another paper. That too journal. Woo hoo !!)"

Coming to the next point where he got smacked by his "so-called" friends, when he was with them, enjoying bourbon,  on how he gets flashes of light when he sees his wife at home, he got goosebumps. All the time.

Something in him realized that these flashes were getting converted into something to give him goosebumps. This was the realization.

PHOTO = light,  and Elektron = electron a.k.a Current . Something workable.

That came out to be the photoelectric effect.

Giridhar MadrasOpen access

There is an editorial in The Hindu on open access. I have written about this before in this blog several times. 


While Harvard spends around $4 million of its $400 million budget on the library (i.e., 1%), IITs/IISc spends around $2 million per year on its library budget, which is nearly 5-10% of the overall budget. Much of these are wasted on commercial publishers while the cost of many society journals are still manageable. It is rather critical to understand the differences between a society and a commercial publisher. I have written in detail about the differences in commercial and society publishers and the need for a faculty to understand the cost involved in publishing. 


While nearly 80% of the IISc budget is paid to the commercial publisher, less than 40% of the articles published by faculty are in journals published by commercial publishersA librarian (especially in India) wants to buy the entire package sold by the publisher as the commercial publishers continue to add journals without adding to the contentLibrarians would withdraw from "big deals" and ask themselves what the faculty actually needs. At the initial stages (like the new IITs), the librarians should ask the faculty to buy the journals as individual subscriptions and subsidize it through institution funding rather than get institution-wide site licence.


Recently, in a meeting with the publishers, I was appalled to see Springer quoting nearly $100,000 for subscription to each new IIT. Many new IITs do not have any reasonable number of faculty and the number of full text downloads are minimal (< 1000). When questioned why this cost was nearly 10 times that offered to an Indian university, they were quick to point out that IITs are funded better and may have higher usage later. This differential pricing (depending on the ability to pay) is ridiculous. This is like that the price of a car is determined depending on my pay and   how much I will use the car !


Later in the meeting, the representative made a statement that scientists can not survive without them. In USA, statements like this leads to scientists withdrawing from editorial boards, refusing to review and publish with these publishers. Not that it may make any difference, but as a scientist, I will not publish any more with journals published by Springer.

FëanorRoman à Clef

The late Michael Dibdin, author of black tales of grit and grime set in various Italian cities, liked to lend an atmospheric aura around his detective Aurelio Zen. With a name like that, it should be obvious that the investigator was a multifaceted talent. In And Then You Die, he takes a moment from undercover copping in Rome to enjoy his usual repast.
'So where were you? 
'At the end of the earth, Ernesto. It's a long story, and I've got an appointment at the office in fifteen minutes. Meanwhile I'm ready for some real food.' 
'Right away, dottore! The usual?' 
'The usual.' 
Ernesto took one of the filled rolls from the glass cabinet, set it on a plate, then added two more thick slices from the roast and set it down in front of Zen along with a small carafe of white wine and a knife and a fork. 
'I carved it extra fatty,' he said with a conspiratorial wink. 'You're looking a bit peaky, dottore. We'll have to feed you up.' 
Zen cut a chunk of the pale, perfumed meat and started to chew. Apart from wine, Ernesto only served one thing: porchetta, choice young piglets from farmers personally known to him, stuffed wtih fennel and herbs, slowly roasted to moist perfection on a spit and served cold with chewy fresh bread. The crackling was a crisp layer of rich delights, the fat a creamy, unctuous decadence, the flesh tender and aromatic. Even the generic Castelli Romani wine, which couldn't have been given away free as a household cleanser in Venice, tasted blandly acceptable to Zen today.

Madhurima Daswalk the distance..


I walk the distance
Feel the sand slip through my toes
The rising sun spread its rays
The fishermen saw the sea
Little children collecting shells
With a soulful purpose
Unfinished chores
Boundary less dreams
I walk on to write the story
Find myself on a bench
That must have seated
Hearts many
Secrets shared
Giggles resounding
Love tales written
Life found meaning
Each day is a rising sun
That fabricates the lanes and stops
The turns we take
The halts we make
Are like the sand gone by
Impressions left for a while
To be rewritten by an unknown face
We all walk the distance
Discover the chance and expanse.

Madhurima Dasravivaar ki shaam..

haath mein coffee ka gilaas,
shaam ka bujhta sooraj,
choti si baatein,
glider ka garajna,
armaan aasmaan ka,
makhmali hawaa,
aur tumhara saath!

Kapil BodkheBrown Rice

Having started exercising on a regular basis, I've also started keeping an eye on the food that we eat. Through one of my friends, I came to know about the benefits of brown rice. I did some research about brown rice on the internet and here's a succinct summary of my findings:

§ What is Brown Rice?
Brown rice is also called 'unpolished rice' and is brown in color. It is actually how the rice would look before it goes through the entire process of polishing. Every rice grain has an outer layer of a slightly stiff cover called the 'hull' or husk. The husk is always removed from the seed for both white and brown rice. Under this layer is a thin brownish layer called the 'bran' layer. This brownish layer on the rice seed clings to the seed and is removed through a polishing process. In the case of brown rice, the brownish bran layer is left intact and only the top stiff cover is removed. 

§ Health Benefits
The most important benefit of brown rice is that it is rich in fiber, which is present in the brown bran layer of the grains. The health benefits of a high fiber diet are being stressed by medical experts and this alone is a very good reason why you should eat brown rice instead of the regular white rice. The health benefits of high fiber content foods are numerous, it reduces the possibility of heart diseases, helps avoid abrupt spikes in sugar levels, helps digestion and reduces constipation etc. Some medical tests have indicated that the health benefits of brown rice could include controlling high blood pressure. Besides high fiber content, brown rice also contains other nutrients like, B vitamins, manganese, selenium and iron. By eating brown rice, you will also get the health benefits that such nutrients give the human body. 

§ Pricing
If you thought that brown rice would be cheaper than white rice as it is only partially processed, you are wrong. You will find that in most shops and grocery stores, brown rice costs much more than white rice. This is primarily due to the shorter shelf life as comapred to the whote rice. Brown rice develops a rancid flavour if stored unrefrigerated for more than 5 to 6 months. This is due to the natural oils in the bran layer becoming stale with time. Another reason could be that brown rice despite its growing popularity, has a total consumption that is less than white rice. The economies of larger production scale work in favour of white rice as far as pricing is concerned.

§ Storage
If you look at the brown rice grains, you will notice the brownish bran layer that clings to the grain. In the normal process used to get white rice, this bran layer would be taken off in a polishing process. It is this bran layer that can be affected by prolonged storage and give the brown rice a rancid flavour if stored for more than four to five months. The rancid flavour of brown rice when stored for long periods, is due the natural oils in the bran layer of the rice grains becoming stale. You can increase the shelf life of brown rice by refrigerating the (uncooked) rice. However if you make a direct comparison, white rice has a longer shelf life as compared to brown rice. When you shop for your brown rice, check the manufacturing date on the packet and choose a store that has a high customer turnaround. 

§ Taste
If you compare the texture of brown rice and white rice after cooking, the brown rice will have a much firmer texture than white rice. It is this nutty kind of flavour that makes people love brown rice once they have tried it. White rice on the other hand gets a little more soft when cooked. Brown rice has an appetising flavour of it's own, on the other hand white rice is often enhanced with other flavours. Some Asian countries have become experts in adding flavour and fragrance to white rice. This is very rarely done in the case of brown rice and the natural flavour of this rice is one of the reasons for it's growing popularity. 

§ Cooking
Most of us are quite used to cooking white rice and the basic concept remains the same when cooking brown rice too. However, when you make brown rice make sure that you allow the rice to soak in the water for around 25 to 30 minutes before turning on the heat. This is the right way to cook brown rice as the grains are a bit more tough and stiff. Soaking in water before cooking the brown rice helps to soften the grains. Cooking the brown rice with too much of water makes the grains stick together and feel like a paste. On the other hand using too little water to cook brown rice will, make the grains too stiff and will also not bring out the full flavour of brown rice. Many cooks would offer advise on how to cook brown rice, but it is best for you to learn the basics and then do the fine tuning to suit your taste. When working out the proportion of water to be added to cook brown rice, start out with a 1:2 ratio. This means that you add 2 cups of water to 1 cup of brown rice. Complete the brown rice cooking and check the texture of the rice by eating a few cooked grains (allow to cool sufficiently before trying this). This will give you a starting parameter to work with and you can then make subtle changes to the time that the rice is soaked (before cooking) and also the proportion of water and brown rice. 

§ Suggestions
If you have never eaten brown rice before and would like to make a start, a good idea would be to mix one portion of white rice and one portion of brown rice when cooking. Gradually reduce the proportion of white rice and allow the brown rice to be the major portion in your rice consumption. You will soon start liking the full, rich nut like flavour and texture of brown rice. Continue with your brown rice diet and if you ever try white rice again, you will immediately feel that it has a bland and starchy flavour that does not impress you. Few people change back to eating white rice after having eaten brown rice for a couple of months. 

Make sure that you see the packing date on when you buy brown rice. You should ideally consume the brown rice within 3 to 4 months from the packing date. Refrigerating it in a tightly sealed plastic bag can increase the shelf life to around 5 to 6 months. Storing brown rice beyond this period gives the rice a stale rancid flavour. 

You might find that some brown rice seeds are very brown while others look like they have been partly stripped of the bran (brown layer). This is because the polish process may be completely left off (fully brown seeds) or partially done. In cases where the brown rice is partially polished, the seeds could appear to have a lighter shade of brown or even appear a bit patchy with brown and white patches. The cooking time and soaking time for the rice might differ based on the extent to which the rice is polished. A little practice would enable you to work out the right amounts of soaking time and the right quantity of water to be added when cooking your brown rice.

Rahul SiddharthanIs self-plagiarism bad?

Duplicating text from one’s own work is widely regarded, in India at least, as a lesser crime than plagiarising from someone else; some (including senior members of our science academies) don’t see it as much of a problem at all.

Elsewhere, however, as reported by Retraction Watch, a senior and heavily-cited Columbia University chemist, Ron Breslow, has been tripped up by this. He is the sole author of all three articles, so there is no question about who is responsible. His comments to Nature suggest that he has a similar point of view on these things to many Indian scientists — in particular, suggesting that this sort of thing is OK in a review article. The journal editors disagree. The matter is still under investigation.

My take on this is, when you write an article for a journal — as opposed to an e-mail to a colleague, or privately circulated notes for your course — the journal assumes that the content is new and original. This assumption is equally made of a review article as for an original research article. If you cut and paste from your own earlier work, without making it clear that you are doing so, then it is a problem. In particular, if you have published the previous work in another journal and transferred your copyright to that journal, then you legally cannot re-use the same text in your later article — even if you wrote it yourself! But even if you retain the copyright, it seems ethically dubious.

To quote, while making it clear that it is a quote, is a different matter: that is neither legally nor morally wrong, in my opinion. However, it is still a problem if you overdo it. Journal editors, who want to publish original content, may look askance at an article much of whose introduction consists of quotes from elsewhere.

[Update] This is much worse than what I realised from the Retraction Watch writeup. This particular example of self-plagiarism is without question bad — it’s not even a close call. See Abi’s post (and his comment below), and the linked pics from Stuart Catrill.

[Update 2] The Nature article from 1992 mentioned by Abi, about two researchers’ efforts to correct erroneous papers from Breslow, is unfortunately paywalled. Fortunately Ashutosh Jogalekar has written a detailed summary of that article. Go and read it to appreciate the true extent of collusion that can occur between influential scientists, journal editors, and reviewers in these cases. And I would add, in the interests of science, Nature and other journals should not paywall such articles. Even if you are not an open-access convert, please open at least the commentary articles to the wider public!

And I have inserted the scientist’s name into the text above — I didn’t originally name Breslow, perhaps because my point was about the question of self-plagiarism and not about the individual. But I now see that the individual’s actions are sufficiently egregious to deserve being called out — as many others have done in recent days (see Ashutosh’s blog for links).

Ram R

Lalit PatnaikKhidki kholo andolan!


Corporate offices started the trend. Government and public sector offices caught up with it. And now even educational institutions and homes are following the pointless practice. I call it the 'cocooned-indoor-syndrome'.

By constructing closed and cocooned work-places - where you don't have a sense of day or night - the trend-setters i.e. the employers probably expected you to work away without concerns of passage of time. But for heaven's sake, I hope they realized that most of us have at least five different ways - own watch, cell phone, corner of the desktop, co-worker's watch and hunger - of finding out what the time is. Once the trend is set, you always have hordes of followers who actually don't know why they're doing it but will still do it convincing themselves with excuses like 'higher standard of living', 'progress', and 'development'.

When you have so much of natural light available during the day, why does everyone keep themselves locked inside dark dungeons that need (read waste) thousands of valuable watts trying to light up the work-space?

But yes, lighting takes up only peanuts of power when you compare it with the most gluttonous of all electrical loads - the air conditioner. So the idea is you make your work-space air-tight and then install air-conditioners to heat the surroundings of the building (well actually, may be to cool the indoors so that people inside can use suits, jackets and shawls) well enough so that people coming from outside crave even more for the air-conditioned interiors. In most cases, ceiling fans are more than enough. How about planting lots of trees around the building and opening all the windows? Why not take care of cooling and ventilation in a much more economically and ecologically saner way?

The cynics say "Can you bear 40 degree Celsius?". I answer "It certainly is difficult. But, if I don't bear it now and give in to AC's, I might have to bear 50 degree Celsius within a decade!". If you feel for the cause, do join the 'khidki kholo andolan' (losely translates to 'the open-your-windows movement').


[Disclaimer: Most of the above arguments hold for hot countries like India and not for cold countries]


Lalit PatnaikWhat's in a name?

This one is one of my favorite Richard Feynman anecdotes. [Quoted from http://www.vigyanprasar.gov.in/scientists/RichardPFeynman/RichardPFeynman.htm]

Feynman's father Melville Feynman encouraged his son's fascination with science in all possible ways. While not pushing in any particular direction his father would explain things about the way the world worked. Melville taught his son at a very early age 'the difference between knowing the name of something and knowing something'. To quote one of Richard's oft-quoted anecdotes about his father: "See that bird?" he says. "It's a Spencer's warbler (I knew he didn't know the real name)". "Well, in Italian, it's a Chutto Lapittida. In Portuguese, it's a Bom da Peida. In Chinese it's a Chung-Iong-tah, and in Japanese it's a Katano Takeda. You can know the name of the bird in all the languages of the world, but when you're finished, you'll know absolutely nothing whatever about the bird. You'll only know about humans in different places, and what they call the bird. So let's look at the birds and see what it's doing - that's what counts!" 


I've seen so many people - when they realize they haven't understood something correctly - trying to push their way through arguments and discussions using some high-sounding technical jargon. That's what we can call the Spencer's-warbler-syndrome. When reason fails, vocabulary takes over! My only suggestion, admit your mistake and move on.



Kapil BodkheRat Race


I finally found out the perfect definition of Rat Race in the book 'Rich Dad, Poor Dad' by Robert Kiyosaki. Here's an excerpt from the book:

"If you look at the life of the average-educated, hard-working person, there is a similar path. The child is born and goes to school. The proud parents are excited because the child excels, gets fair to good grades, and is accepted into a college. The child graduates, maybe goes on to graduate school and then does exactly as programmed: looks for a safe, secure job or career. The child finds that job, maybe as a doctor or a lawyer, or joins the Army or works for the government. Generally, the child begins to make money, credit cards start to arrive in mass, and the shopping begins, if it already hasn't.
"Having money to burn, the child goes to places where other young people just like them hang out, and they meet people, they date, and sometimes they get married. Life is wonderful now, because today, both men and women work. Two incomes are bliss. They feel successful, their future is bright, and they decide to buy a house, a car, a television, take vacations and have children. The happy bundle arrives. The demand for cash is enormous. The happy couple decides that their careers are vitally important and begin to work harder, seeking promotions and raises. The raises come, and so does another child and the need for a bigger house. They work harder, become better employees, even more dedicated. They go back to school to get more specialized skills so they can earn more money. Maybe they take a second job. Their incomes go up, but so does the tax bracket they're in and the real estate taxes on their new large home, and their Social Security taxes, and all the other taxes. They get their large paycheck and wonder where all the money went. They buy some mutual funds and buy groceries with their credit card. The children reach 5 or 6 years of age, and the need to save for college increases as well as the need to save for their retirement. .
"That happy couple, born 35 years ago, is now trapped in the Rat Race for the rest of their working days. They work for the owners of their company, for the government paying taxes, and for the bank paying off a mortgage and credit cards.
"Then, they advise their own children to `study hard, get good grades, and find a safe job or career.' They learn nothing about money, except from those who profit from their naïveté, and work hard all their lives. The process repeats into another hard-working generation. This is the `Rat Race'."

Kapil BodkheThings to remember while riding a motorbike


Here are some of the lessons I’ve learnt while riding motorbikes in various parts of India:
·         Choose a bike with wide tyres. Bikes with wider tyres are stabler and have a lesser tendency to skid.
·         Don’t overuse the clutch. Use it only while changing the gears or coming to a complete stop. Don’t use it while riding downhill. Excessive use of clutch wastes fuel and also reduces engine life.
·         Switch off the engine while waiting at the traffic signal. Avoid excessive throttling while waiting at the signal.
·         Slow down on the speed-breakers. Speeding on the speed-breakers can cause severe back pain.
·         Always keep an eye on the tyre pressure and stick to the recommended settings. Insufficient tyre pressure not only reduces the life of the tyres, but also increases fuel consumption.
·         Refuel the bike only at the selected and trusted fuel stations. Constant variation in the fuel quality might affect the performance of the bike.
·         If you are riding in a group, keep the headlights on even during the day. Makes it easier for your fellow riders to track you.
·         A simple rule to check whether a person driving ahead of you is able to locate you (especially for the trucks that don’t have the center rear-view mirror) - if you can't see the driver in his rear-view mirrors, then he can't see you.
·         If you are being chased by a dog while riding (very common in India), don’t try to speed away in panic. Just stop for a while. Most of the times, the dog will stop chasing once you stop. Dogs have a tendency to chase moving objects.
·         Enjoy the scenic views, the gushing wind, and the adrenaline rush while riding!

Daniel Mascarenhas(Bike) Tour the Bay Area

Don't wait to go cross country, go overnight, says Bike Overnights. A long bike tour is my dream vacation. A day will dawn, when I will ride the open road in front me over thousands of miles. But until then, I will have be content with overnight bike tours on weekends.
The SF Bay Area is blessed with gorgeous scenery and pleasant climate that make many bike tour options possible.

I wrote about my first bike tour, Santa Cruz – Monterey – Carmel, last labor day weekend, which was published in Bike Overnights. This route takes you through the farmland and sand dunes of central CA coast. Public transit is available from SJ to Santa Cruz and from Monterey to SJ. It is generally a good idea to go south as the winds tend to be from the north. Veterans park campsite is the best option for a night stop on this trip.

SF to Santa Cruz is a fine touring option too. We started at the SF Caltrain station and followed the waterfront, first due west and then south till we hit Hwy 1, which takes you all the way to Santa Cruz.
The trip is about 90 miles. We stopped for the night at Pigeon Point lighthouse hostel, a fun and affordable place right by the ocean. The hot tub overlooking the ocean is pretty sweet. The hostel has a fully furnished kitchen where you can cook your meals. It's a great place to meet other fun people. And the elegant white lighthouse on a the rocky coast makes for a postcard picture. The scenery along the route, as with all of coastal CA, is beautiful. Farmland, small towns, hills, dunes and beaches. And Swanton Berry Farm in Davenport, with its delicious food and honor payment system is a must visit. Don't forget to catch some surfers in action near the lighthouse in Santa Cruz. The Santa Cruz to SJ bus service is a convenient connection to the south bay to complete the loop.

The SF – Bodega Bay – SF tour takes your through the rolling hills and farms of Marin and Sonoma counties. We headed north through Fairfax and Nicasio, east of Three Peaks in Marin county.
I loved the cozy and rustic feel of the small towns in Marin County. It is a world away from the hustle and bustle of the Bay Area. Cows and sheep grazing on the verdant hills make it perfect picture. A stretch of road through a redwood forest calms the soul. We camped at Doran City Park, a basic but comfortable campsite that has showers. The next day, we headed south along Hwy 1 until Stinson Beach, took the Panaromic Hwy to cut across east to Mill Valley and onto SF. The ride along Tomales Bay and Bolinas lagoon is quite spectacular. And the Panoramic Hwy needs to be given due respect for challenging every muscle and sinew in my body. All in all, a hundred and fifty miles of unending bliss.

Soak in the wine country as you pedal through the storied vineyards of the world famous Napa Valley.
Our tour started with a trip on a ferry from SF to Vallejo. We then headed north towards Napa and hit the Silverado Trail. Miles and miles of bright green vineyards, interspersed with beautiful wineries. Bothe-Napa SP makes for a good stop for the night. It has a hiker/biker site and all facilities. Day two took us east over the hills into Santa Rosa. Hop on a Golden Gtae transit bus to get to SF. This 65 mile trip is great way to see one of the most famous wine producing regions in the world.

Big Sur, a bit of heaven on earth. I had blogged about the Big Sur bike tour with Almaden Cycling and Touring Club. I didn't do this ride as a self supported bike tour. It might be a little too strenuous to bike this loop on a fully loaded bike. But the brave souls who take this one on, will be duly rewarded. Big Sur is definitely one of the most beautiful places I have visited. Take it all in at the relaxed pace of a bike ride.

Some useful tips for aspiring bike tourists. Map your ride using Ride with GPS. This website gives elevation profiles of your route. Your pace will be much slower on a hilly terrain as compared to a flat one. Also check for wind directions as a strong headwind is like a continuous uphill not followed by a downhill. Gear includes a touring bike (or a road bike with a metal frame), panniers, tools and camping gear. I have a Novara Safari touring bike with Ortileb panniers. Go discover the Bay Area, one weekend overnight trip at a time.

Richa MalhotraSome reflexions

Recalling an experience of a lifetime…

The International Congress of Mathematicians (ICM) takes place once in two years. For the first time in history it was held in India, the land that claims the birth of zero. Exactly a year ago, I was in Hyderabad attending ICM, reporting from the conference, for the newsletter with the masthead REFLEXIONS. The name of the newsletter was decided after long discussions over luncheons. As part of the newsletter team (and the only female reporter on board from day one to the last day of the conference) I had one of the most mind boggling experiences of reporting.

Courtesy: Rahul 
The idea of a newsroom with deadline pressure shooting through the roofs was very much felt under the guruji Bajji. Bajji alias R. Ramachandran, Frontline's associate editor was the press in charge. Yet, working under him meant “fun” – to sum it up in one word. It is hard to forget those sleepless nights when we sat together to bring out the day’s newsletter and got back to the guest house to catch one or two hours of sleep. We later discovered that Bajji had not availed that either – when he would doze off in the newsroom to make up for it! (I recently interviewed Bajji. If you are still wondering how he got this name 'Bajji' then let me tell you that I have no answer to that. We did struggle to get the secret of his pet name but all in vain. Rumours have it that it goes back to his TIFR days.)

The coolest person on board was my dear mathematics Professor G. Misra, popular among the team members as “Misraji”. No matter what went wrong in the newsroom (no power supply in the night, no internet service on the team’s arrival with press release waiting to be mailed, phones ringing repeatedly with someone demanding at the other end or even worse if after a whole night’s hard work, the newsletter would not arrive from the printing press on time), the spirit was ALWAYS maintained, thanks to Prof. Misra’s timely jokes of all sorts! Sometimes, we popped out of our chairs bursting out in laughter.

I cannot finish my blogpost without mentioning Prof. B. Sury, who stood out from the rest by coming up with the most incredible headlines for our stories, sometimes the funniest. I reckon how much he had sweat in the newsroom! Other people in the news team were young journalism students from the University of Hyderabad – most of whom are placed in newspapers now. One of them is an amazing photographer (he gets all my “likes” on his facebook profile for the smashing clicks), another is training with a national daily, one is working in a regional daily, and I have lost whereabouts of the fourth and fifth.The coffee machine was simply the best companion to have; with team members doing rounds of making coffee, served in multiples, sometimes spilling all over the place. All that contributed to keeping us high on work.

ICM was a get-together of about five thousand mathematicians – it was more like a ‘mela’, if I may call it so. I have in my life never seen – I did not even know – that such huge a number of mathematicians existed on the face of earth. So much so that there was almost a stampede at the gala dinner. We did not even enter the venue, by choice. There were still some more who did not grace the occasion with their presence.

Exactly a year has gone by; memories have started to fade but the experience clings. I recall that on the last day of the conference, everyone had a long face. Yet there was an intense satisfaction within, of having striven to bring out REFLEXIONS – loved by many an audience. One blunder made it to the last page of the last edition of the newsletter. A young reporter from the team used his Googling ability a night before to get the photograph of an award winner wrong (in a snippet authored by me, without my knowledge). We could not correct the published picture nor could we carry an erratum as it was the last edition. The awardee walked into the newsroom with fear dripping from his face, fear that the person in the photograph would claim his award money...

The pre-coverage of the ICM can be looked up at as

Sujit Kumar ChakrabartiThe Fallacy of Influencing Others

I grew up with ambitions of 'making it big' in many ways. I wanted to be a scientist whose inventions would change the world in the way those of James Watt and Addison did. I wanted to be a teacher under whose tutelage scores of youngsters would imbibe my own ideology and knowledge structure. I always wanted to 'move up the value chain', always wanted to do stuff with bigger impact factor. I wanted to be the man whose achievements (and even the obituary, literally) would feature in the front page!

The realisation of my littleness has most joltingly hit me when I learned to observe how little the various aspects of me, my life, my achievements, my strengths, my insights etc. mean to others. Let me cite a very little example. I have always made it a point to shutdown my computer before leaving office. Very simple reason of saving energy. After all arguments about how ineffective my little move would be in saving the world, I eventually reached the conclusion that it costs me nothing to do it anyway. So, I made it a practice. I routinely kept sharing my thoughts with my colleagues -- people with whom I have always shared great rapport and respect -- and very politely kept requesting them to adopt the simple practice. In spite of all initial resistances falling apart, and in theory accepting my argument, I found not a single person changing his habit! It was a phenomenally frustrating experience. It made me acutely aware of how little the power of argumentation and logic is in front of long-standing habits and attitudes.

My daily life is filled with innumerable experiences of the above kind. I have failed routinely in influencing people through model behaviour. People are exceptionally resistent to change even when you present a flawless example of a triumphant best practice. A large portion of the population doesn't even have faith in the idea that thoughts can be used to tune important behaviour.

I always thought that I was well aware that people take offense if you put your virtues on naked display. Even staking claim on such qualities as modesty, magnanimity, civic sense etc. is very dangerous and immediately invites defensive stance from the onlookers. Far from genuinely appreciating, people try to mock you, tag you as pedantic, or simply overlook the reality to protect themselves from an exposition to questions on themselves. Therefore, I try being polite, even meek, when I realise that my behaviour may make people feel defensive. And yet, I have received stone-cold response to any suggestion of improvement, however little they might be, from every quarter -- strangers, colleagues, elders and youngsters...even family and friends. I have felt poisonous bitterness on how little of my most prized insights, I have ever been able to even mention to people who really matter to me very much. Transferring those insights in effect remains a distant dream in such circumstances.

The Two Types of Virtues

Here, we are talking about two types of virtues. One are selfish ones, while the other are the altruistic types. Just to give a sense of completeness, virtues are benefitial characteristics. If the beneficiary is the self, the virtue is selfish. If the beneficiary is someone else, it is altruistic.

Some examples of selfish virtues are : Being fit, being intelligent, being rich, being knowledgeable, being good-looking etc. Everyone want these virtues maximally. If you see someone else having it more than you, you may love or hate that person, but definitely would like to get ahead of the person in terms of possessing that virtue if possible.

Altruistic virtues: honesty, integrity, hardworkingness, truthfulness, helpfulness...They are tricky ones. People don't necessarily want them. If someone has one such virtue in some amount, he tends to look down on those who seem to have less of it, and tends to consider those who seem to have more of it as pedantic, sometimes overbearing, and sometimes even vain. And the trickiest part of it is that people always hate you for showing these virtues off. Showing off your wealth, or beauty, or one of those selfish virtues, can be pardonable. But to show off you your honesty or magnaminity is unpardonable. Here showing off doesn't merely mean boasting. Even practicing the virtue may be interpreted as showoff. I remember an incident long time back when a gentleman was visiting me in IISc. A professor passed by on a bicycle. I proudly pointed this out to them. To this, this gentleman reacted like, ‘You know, people will always show off their simplicity.’ I was shocked! I asked him why being a professor (read 'intellectual'), who had probably given up a lot in his life much lesser beings had continued enjoying, was expected to be so modest even about his simplicity? I wondered, if you are allowed to show off money, beauty, power, influence, fame, why you aren’t allowed to show off your simplicity!


A very interesting distinction between selfish and altruistic virtues is the proportion of destiny and decision in them. The amount in which you have any of the selfish virtues could largely be due to destiny. For example, how beautiful you are isn't significantly in your own hands. Nor your intelligence or richness. On the other hand, how much of any altruistic virtue you possess appears to be predominantly a matter of decision or choice. For example, how honest a person is is completely dependent on the way he conducts himself volitionally. Whether apparently volitional acts are indeed volitional or are puppets of our genetic makeup is best left to a deeper analysis in the purview of the problem of freewill.

Why Altruistic Virtues are Hard to Imbibe
Why is it so difficult to influence people to observe higher standards of ethics than they presently do? Ethical behaviour is tied to altruistic virtues. And, as mentioned above, the amount in which one has any of those virtues is a matter of decision, not fate. People, particularly adults, find it harder to be caught erring in matters of decision than in matters of destiny. If someone is richer than me, I may envy him, idolise him, may want or not want to be like him. May even want to kill him for money or envy. But in the end, I will take solace in the fact that richness after all is significantly a matter of fate. However, if I find someone behaving more honestly than me, accepting his level of honesty to be a better thing than my level of honesty is equivalent to accepting my mistake in the decision as to how honest I would want to be. The blame of not having enough of that virtue squarely falls on me, my conscious self. You see my point?!

The other reason why people seem to resist accepting ethical superiority in other and accepting ethical lessons from them is because altruism seems closely tied with ego manifested as vanity and pride. Recall the above incident of the gentleman reacting to a professor's simplicity as a sign of his vanity. The reaction was almost a reflex action. Even before conscious analysis sets into motion, we start interpreting, as if by reflex, any altruism in excess to what we have as show off. The behaviour, though may appear strange, is explanable. Ethical behaviour doesn't lend itself to simple explanations of reward and punishment. A lot more than simple cost-benefit analysis goes on when we behave ethically. Therefore, unless we find an ethical stand natively present in us, we react in a puzzled way to any of its appearance. The easiest thing to attribute ethical behaviour (in excess to ours) is to vanity and ego. There may be some truth in that; hence it can't be outright dismissed as absurd. But, it's hard to verify its truth; hence, it should be looked at with scepticism.

Understanding Altruism
Let's give a moment's thought about why be altruistic at all. Perhaps, it will show some ways to bring down the some part of the resistence people (we) show for accepting ethical lessons; and will hopefully help reconcile with the part nothing can be done about.

Above, we mentioned the connection between altruism and ego. There definitely is a part that ego plays in altruistic behaviour. A clear proof of that is seen in children. Most of the 'good' things they initially do, e.g. sharing toys or being gentle with fellows, is all to escape punishment or gain appreciation. A slight bit of honest introspection will indeed reveal (at least it does to me) that many of the altruistic acts we do even when we grow up are still due to our need to be appreciated. An excessive craving for appreciation may lead us to behave altruistically to the extreme, by self-sacrificial acts, even extending to self-destruction.

But again, to attribute all altruism to ego is clearly a mistake. First of all, as many studies show beyond doubt, altruism has survival benefits. And hence, as a genetic trait, it has survived and succeeded. People who are altruistic may be genetically predisposed to behave that way. So, to try and explain away altruistic behaviour completely on the basis of ego boost and vanity would be a mistake.

From a more psychological perspective, altruism is also a matter of faith. We all have our faiths about ourselves, the world we live in and the relation between the two. I consider my example. I like to believe that I live in a world that is, like me (as I think of myself), something good, even divine. Being altruistic gives me a feeling of belongingness. It re-inforces my faith in life and its meaningfulness. I live with a hope that the world can be that good place that it inherently is; and an act that takes it even a tiny step towards it is hugely re-assuring to me. I truly believe that this line of thought is devoid of vanity. Probably, like vanity, it again models altruism as an inherently selfish act. But, in the process, we don't lose any of the beauty that we associate with altruism, because it is devoid of vanity.

Conclusion
Propagation of ethics is hindered by many causes. Two cited above are what I can see. There could be more. The knee-jerk resistence that people display to the idea of true altruism, by attributing it completely to vanity, has its roots in lack of awareness and thought; hence, can be debunked through arguments pointing out other causes of altruism. However, the other type of resistence, the one arising from the resistence to accepting one's mistake in making ethical (0r any) decisions, is a deeper one. I don't see any clear way to deal with this natural problem. I don't know how much of our overall resistence to ethical lessons we feel due to which of the above two causes. I tend to believe that the latter one has a larger share. And that significantly dampens my optimism about there ever being invented a method of imparting ethical improvements on people which is manifold more effective than any that exists.

Pradeesha AshokManju(Snow) by M T Vasudevan Nair

This short novel by one of the most gifted Malayalam writers made me think about something very inevitable in our life; something  that will make you excited,  sometimes desperate, sometimes disappointed. It is a verb, a noun, a pronoun and a feeling...Yes, Manju made me think about "waiting". 

This is a story of people, in a faraway hill station, each of them waiting for someone. Vimala, a teacher in a residential school, is waiting for  Sudheer , who, touched her heart years before. Buddhu, the boatman, is waiting for his father, who he has never seen, to come back.  When the hill station is getting ready to welcome tourists, these people are waiting for some tourists to come back and give meaning and hope to their lives.

In spite of being a novella, the main protagonist, Vimala, is a well-defined character. Her life, family background, emotional setup etc are well-etched. The other characters who appear in between somehow supplements her loneliness.

A well narrated story. 3.5 out of 5.

Trivia: made into a movie later.

Chetana BaligaThe calm after the storm

We had welcome rains in Bangalore yesterday - well, welcomed by all but the spectators of the IPL match at Chinnaswamy, I guess ! The showers soaked the parched earth and soothed the fevered minds of people. It rained through the night, as the people slept fitfully to the lullaby of the pitter-patter rain drops.

The morning after, is glorious. The sun shines benevolently, a gentle breeze runs through the trees, the birds chirp, squirrels squeak and run around with renewed enthusiasm. The grass looks greener, the ground is strewn with gulmohar petals, giving a red carpet welcome to the early risers. The entire campus looks as though it has been scrubbed clean for the arrival of some dignitary.

As Robert Browning would say -
THE year 's at the spring,
And day 's at the morn;
Morning 's at seven;
The hill-side 's dew-pearl'd;
The lark 's on the wing;
The snail 's on the thorn;
God 's in His heaven—
All 's right with the world!

P.S. Wonder why the snail is on the thorn - ouch!

Large and red, red and large
Like a rose-coloured barge
Upon the river Thames
But I am not liking your friendship with that man called James
It is the only blot on my love pure and simple
Which is like the soft soft dimple
On your smooth and buttery cheeks
On which I am taking many peeks
Only my love is not parasitic
Like rafflesia but it is stalagmitic
Growing slowly and maturing with time
Like an old pond with green slime
I am truly in love with you
But everyday your behaviours are teaching me something new.

Deepak Malani[article] The IIT Braindrain


The Fifth Estate is an official student magazine at IIT Madras. An article in their March issue investigates a few questions addressing the career move of engineering students towards non-core jobs. The article takes inputs from students and faculty across IITs, debating on continuous evaluation, exam fever, attendance rules, placements-money_factor correlation. The post begins with a rhetoric
Why can’t the current system ignite a passion among its students about the engineering they learn in their four or five years? [...] 
Starting with an optimistic opinion one of the professor comments
it is always beneficial if someone with a good knowledge of Engineering takes up management or government roles, where they can use their engineering knowledge to better understand technical problems[...]
and goes on compare that workload on students in US universities is rather much higher than their Indian counterparts
In today’s system, everyone concentrates on getting highest level of performance, and pushes students through too many hurdles. This deteriorates the enjoyment factor in education. Students should be allowed to learn at their own pace, directing more effort towards learning fundamentals [...]
Another professor suggests a pedagogical technique, to incorporate collaborative learning among students.
The professor teaches fundamentals for about half a semester. For the remaining part, students are divided into groups and assigned particular topics on which they are expected to do research and read up for about a month. After this, new groups of four each are formed by taking one member from each of the original groups. Within a group, one each member has mastered a different topic. They spend the last month of the semester teaching these to each other. In this method, since students actively participate in learning as well as teaching process, their fundamentals become clear.
And the concluding observation, correlating non-core sectors paying higher salaries than the core engineering jobs, sits at the top of the analysis.
There are just too many job positions being offered that require no engineering expertise at all. A student who acquires more knowledge in his field most often ends up with a lower salary core job as against his friend, who may not have learnt anything at all in his department, but is doing a non-core job. So, what motivation do the students have to learn engineering [...]

Mogadalai Pandurangan GururajanForeigners in their own country

It is said that the past is a different country. Mukul Kesavan makes a point about how in this country, there exist different countries in the present, and not just in the past:

Walking my children to their school in Brooklyn some years ago, I met panhandlers asking for money at the corner of every block. My technique was to either ignore them or to hurriedly give them change and move on. The natives did things differently; they stopped, exchanged greetings, and only then did money change hands. A fraternal acknowledgement of a poor man’s humanity doesn’t come naturally to desis. This has everything to do with the exclusions of caste. The caste system is distinguished from other forms of social differentiation not merely or even principally by its endorsement of inequality; what makes it unique is its ideological hostility to fraternity.

In India, the poor and the privileged, even those who are modestly middle class, aren’t divided by class; they’re divided by a line of control. The poor, to adapt L.P. Hartley’s famous first line, are another country. It’s a country that we write about or help make policy for — if we’re feeling curious, generous or charitable. Our concern is frictionless because their country and ours might be adjacent but they’re sealed off from each other. It’s only when this line of control is legislatively breached, when people not-like-us have to be admitted into our country, that we find reasons with which to repair the breach. Thus every episode of affirmative action in our history has been met with arguments from merit, arguments against a pernicious ‘creamy layer’ and now an invocation of the ‘real’ problem in Indian education, the reform of the state schools.

Take a look!

Went to Turahalli this morning around 15 km from my home, they call it turahalli forest but there is no forest as such. but definitely somewhat green and peaceful place. There are some good MTB trails to explore, I have only hybrid bike so didn't explore completely.



 Temple on top of the hill while climbing





 I was bit scared when I reached the hill top, there were many eagles flying on top of my head





 Then these guys came to my rescue, shouting "Hiiii Uncleeeee" :-)





 It was very peaceful under this tree on hill top





 My Trek 7.1





 Another view of temple, I like the fragrance of these flowers, brought few in my bag as well :-)




 
 My Trek 7.1 again, looking cool, isn't it ?





 liked it !





 "Right now, the new is you. But someday, not too long from now, you will gradually become the old and be cleared away. Sorry to be so dramatic, but it's quite true. Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma, which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice, heart and intuition. They somehow already know what you truly want to become. Everything else is secondary." --Steve Jobs

Sujit Kumar ChakrabartiThe Forgotten Heroes

Our generation was brought up with very few career choices to pick from, particularly in middle class homes. Engineering and Medical studies were the only so called respectable careers possible. That in itself is so ludicrous and tragic! But worse still was the fact that both being based on science, the love of science that many of us developed was not a love but a compulsion for us all. Not one of us can make out if, even after having spent a lifetime in service of science, science would really have been our first love, had we had the choice to love something else.

No wonder people who don't take up science as a career seem to shun it like a disease. The essential nature of science -- that of asking questions, and using enquiries based on logic and experiments to find their answers -- is completely hidden from most. Instead, what has got ingrained in most of us is that science is what distinguishes the smart ones from the others. Therefore, those who didn't pursue science as a career for whatever reason develop a hatred for it. Who will be stupid enough to accept one's stupidity simply because they didn't become scientists (or technologists). For most, Science appears as a thing which intelligent people make a career out of, and in their spare time, use it to scare and demean others. Most people wish to have nothing with science unless it creates technologies which bring value in terms of entertainment, healthcare, comfort, lifestyle and convenience. That science is by itself a beautiful thing is never considered. And why would it be, when the way it is introduced into our lives is so ugly and distorted?

To some extent, intelligentsia in general, and scientists in particular, are also to blame for this predicament. Most of them carry the illusion that it's their tremendous intelligence which makes them what they are. However, if you look closely, scientists use pretty much the same set of skills which others use to accomplish their tasks. Intelligence is just one of the many properties of a scientist. And I don't see why it should be assumed that pursuing science requires any more brains that anything else? Similarly, the joys of pursuing science are very similar to that of pursuing any other activity. The elitism associated with science is also its greatest undoing.

TV is a potent medium which brings in front of us a wide choice personalities and lives which we and our children could treat as our role models. With the state of affairs as described above, TV channels find it unnecessary and uneconomical to give much of their time to talking about intellectuals, particularly scientists. Probably Discovery and Nat Geo do give some coverage. But I am not sure how close things there are to the spirit of science, with the element of sensationalism they induce. The effect of this on who our children will idolise, and in turn will want to be like, is disastrous I think. In general, mass media, being in the hands of people who are away from science, give a very skewed picture about the population crowding the world, and important things happening around. The people whose images are flashed are mostly movie-stars, sports-stars and politicians. Models. To some extent businessmen and artists. And these days, reality show starlets. But hardly ever intellectuals like scientists, engineers, doctors and authors get any coverage. Similarly, people are always perfectly up-to-date about the movies being released, the wars and protests (sans any indept understanding of the real issue behind them), what's the latest cream in the market which will help keep your skin glowing, how the dance item the starlet presented brought tears to the judge's eyes. Who cares about what interesting ideas researchers are dabbling with, what new secrets about the way the universe works they are trying to unravel, what beautiful thoughts an author is playing with to write his new novel, and what he is trying to say through his stories?

I feel our kids would have got a much more balanced picture of what all could be done with all the time available in a lifetime had there been less fear of science in the current generation; had people looked at it as another way of having fun and expressing oneself like various art forms and sports. In general, I wish we had known how to dissociated the notion of being intelligent with science and intellect. I wish we had identified science for what it is: being curious, asking questions and seeking their answers.

Richa MalhotraAre you a science communicator, journalist or writer?

This is one question that often came to my mind until I asked a "science communicator" (and not a journalist or writer :P) the difference...I guess readers will have differing views and I would like to know them...

Many of us use the terms science communication, science journalism and science writing interchangeably, Toss Gascoigne (President of the Public Communication of Science and Technology Network) identifies them as different profiles. According to him science journalism is where there is a professional journalist who might take an interview with a scientist or scientists, report on an issue, and interpret information to produce a product suitable for the audience. If it involves writing for the Times of India, it might be an article of about 250 words with a photograph and if it is a news story for television, it might end in say 70 seconds. That would be the role of a journalist.

Science writing is not necessarily about news. The first thing that distinguishes science writers from journalists is that they are more likely to have a scientific qualification and are likely to have expertise in science because they have either worked or qualified in that area; many journalists will not have that sort of expertise. The second difference is that a science writer is more likely to write an extended piece or a book chapter or a long article, whereas journalists usually write short pieces. If it is a feature article in a major newspaper, it might go up to 600–700 words.

A science journalist is a mediator and would stand between science on the one side and the public on the other, and would look at science and write about it in the form of a product suitable for the audience. Whereas a science communicator would stand back, observe that process and write about it, but not about science. He would talk about the role and function in training of a science journalist and how scientists should approach the process. He will discuss and describe, count and evaluate the sort of coverage in the media, look at the process and comment on it.

Agreed Mr Gascoigne! And thanks to you I know what I am! Also, I am a blogger, another category to inquire about!


This is a (slightly modified) excerpt from my article published in Current Science. For the complete write-up see: http://www.ias.ac.in/currsci/10mar2011/608.pdf http://cs-test.ias.ac.in/cs/Volumes/100/05/0608.pdf


Richa MalhotraBehind the scene

"I would rather take an e-mail interview than face-to-face", said a journalist I met not so long ago. But what's the issue with a face-to-face interview? Tonnes of hard work! I didn't ask her the reason behind her thinking so because I have a first hand experience in conducting interviews and could guess why...Face-to-face interviews of scientists and policy makers are fun to do but consume a lot  of time and energy...but eventually the outcome is indeed appreciable. Some other science writers I have met and had hours of discussion with, share a similar opinion.

From the various major tasks that are involved in doing and filing a really good interview framing questions (based on background study of the scientist and/or his work), conducting the interview, transcribing the recorded answers, editing the draft, and doing the final touch-up I end up spending hours and hours on transcribing alone. Every time I sit to do it, I wish there was an electronic device that could convert voice into words...What do you wish for when you do the same work? 

Interviews would be more manageable only if the recorders were 100% reliable! I have had poor recordings if the battery of recorder is not fully charged or if there is an aeroplane flying over the building wherein I am conducting the interview, if the interviewee is speaking very softly (in which case I end up holding the device next to his mouth stretching my arm to its fullest from the chair I am perched on!!!) and several other unexpected interruptions...not to mention the phone calls that are received at the other end...I take a deep sigh of relief when the transcribing work is successfully over, as it gets done with a lot of struggle!

What are the positives of a face-to-face interview? Of course, spontaneity of the interviewee, which you cannot achieve over an e-mail because you are bound to get well-thought answers. Next, being able to read the expressions (that speak a language of their own), then an opportunity to persuade the interviewee to answer a question he might not want to answer, et cetera. You may have had other such experiences that I would love to know...

So, what did you miss in an e-mail interview? Length of the answers come down by more than half of that in face-to-face. And of course you miss out the positives mentioned in the previous para. The interview turns out to be like the respected Editor of our magazine rightly said to mewith questions longer than the answers! Certainly, e-mail interviews are easy to manage, as you will not be transcribing or even editing, you can save your precious time...but at times give up on meeting your deadlines owing to the fake promise of receiving a reply...you can perhaps wait for a lifetime after sending a few gentle reminders!

Another way of interviewing is telephonic, which I have tried only once but found worth. This was an interview with Pallava Bagla, Science correspondent and a role model for many of us, budding writers. You can check it out if you want to: http://www.ias.ac.in/currsci/10nov2010/1168a.pdf http://cs-test.ias.ac.in/cs/Downloads/article_46062.pdf

Richa MalhotraReverse Brain Drain?

The latest issue of Current Science, 10 April 2011, features an Editorial on Luring the Overseas Indian Scientist (http://www.ias.ac.in/currsci/10apr2011/957.pdf) (http://cs-test.ias.ac.in/cs/Volumes/100/07/0957.pdf). While the Editorial by Prof. P. Balaram touches upon issues that plague the Indian institutions, it sheds light on a requirement for India, that of reverse brain drain. He writes: "A recurrent theme for discussion is the shortage of faculty to staff the new institutions and to sustain and expand existing ones...The consensus...is that we must make vigorous attempts to entice Indian students and academics who are currently overseas, primarily in the United States, to return and build teaching and research careers in India."


Courtesy: Wordle

I will put this in the context of my everyday observations at a research institution I am currently linked with. Every second visiting student I meet there is aiming for a PhD abroad (not that all of them make it!) The most common PhD destinations being Europe (reason they give is the relatively short duration of PhD, but express dismay later) and USA (reasons being innumerable!). One thing they want to avoid is doing a PhD in India. Those who end up doing it here, in some of the best institutions (like IISc), want to go abroad for a post-doc. Of course research at 'world-class institutions' like MIT, can add to one's skills and such talent could then be used for improving mentorship in the country, but can we not improve the  PhD program in India such that our PhDs could match the international standards and eventually there would be no need for them to return? Maybe not! If this was feasible, we would absorb the already existing PhDs for our universities and there would be no need of reverse brain drain. 


Richa MalhotraSome harsh truths...about speaking, writing and archiving

In a recent editorial in Current Science journal (http://www.ias.ac.in/currsci/10aug2011/257.pdf) (http://cs-test.ias.ac.in/cs/Volumes/101/03/0257.pdf) the big "E" writes about the art of communicating in academics:
"Speaking and writing are an integral part of the life of an academic scientist. Classes need to be conducted, lectures delivered and research papers written. Listening is also a key activity, since seminars are often the most painless way of acquiring new information. Sadly, many accomplished scientists are poor speakers and indifferent writers making communication of their results an ordeal."

Another editorial I came across a little while ago in the journal Science (http://www.sciencemag.org/content/333/6040/267.full.pdf) voices a similar concern but in teaching of STEM (science, technology, engineering and mathematics). It reads: "...most scientists do not have the skills to interact with precollege students effectively."

Current Science editorial goes on to add:
"Lecturers who try to promote interest in science by speaking to diverse audiences often face a daunting task....There are many lecturers who read from prepared texts; a practice more common amongst social scientists. But, in these days of Power Point, there are many who read from slides. If the lecturer stumbles and mumbles the audience suffers silently."

On the aspect of archiving, the editor notes:
"A sense of history, and the importance of preserving past records have rarely been subjects of concern in our scientific institutions and universities. Few institutions in India maintain a well supported archive which can provide scholars, interested in the evolution and growth of our laboratories and institutes, the material necessary for constructing factually correct histories."

In the editorial, an intriguing reference has been made to an article by Lawrence Bragg (who significantly contributed to X Ray Crystallography) on 'The Art of Talking About Science': "Bragg is harsh on the ‘readers’. He [Bragg] writes: ‘I feel that to collect an audience and then read one’s material is like inviting a friend to go for a walk and asking him not to mind if you go alongside him in your car’."

Well, I cannot agree more with Bragg on this! Some friends have eyes for your writings, whereas others just appreciate without a word of criticism, which if made earnestly in a constructive manner, can bolster the writing skills. 

An anecdote that I came across in the editorial is reproduced here:
"...he [Bragg] writes on behalf of those speakers who spend considerable time, effort and nervous energy in preparing and delivering lectures: ‘A lecture is a tour de force and a good and conscientious lecturer is both nervous before-hand and prostrate afterwards’. He advocates a practice in vogue at the Royal Institution where the lecturer is ‘immured in a small private room termed “The Lecturer’s Room” for at least half an hour before the lecture starts’. Bragg narrates a famous anecdote which recounts the origins of this practice. Apparently ‘a lecturer (actually Wheatstone of Bridge fame) ran away from nervousness just before the lecture started, and so a guard has been placed over the room ever since’."

Mogadalai Pandurangan GururajanDenial of tenure for effective teachers!

Here are some thoughts from the latest Tomorrow’s professor post (Message #1170):

The results of this exploratory study provide some interesting insights into the differences in student versus faculty perceptions of an effective teacher. In general, students and faculty define effective teaching very differently. From a faculty perspective, an effective teacher should love the subject and be able to present it in multiple ways. From a student perspective, an effective teacher should be funny, interesting, and able to relate to students.

Here lies our dilemma. From an administrator’s position, if we are dependent on student evaluations to better our professors’ efforts in the classroom and, ultimately, a professor’s tenure and promotion, then are we not concerned when many students perceive an effective teacher as someone who perhaps does not deliver correct information but who keeps them entertained?

If we are interested in effective teaching, then perhaps other methods for evaluating teaching (peer observations, evaluations from those in the field of education, or the model of “teaching to the test”) should be incorporated into the mix. It is disconcerting to think that an effective teacher may be denied tenure because he or she did not induce laughter in the classroom. Again, if we are truly interested in rewarding effective teaching, then let us be assured that we understand the various definitions of effective teaching. If colleges and universities are committed to the idea of teaching and learning, then they must begin by defining this amorphous phrase of effective teaching. Research such as this study only begins to address this issue.

All these might seem fairly straightforward and obvious; however, in my experience, I have  found that these thoughts do need emphasis — lots and lots of — before they become part of our psyche.

Bhargav VKids' Stories - Learning ABCD the fun way

ABCD story for kids!

This is one of P-'s favorite stories.She enjoys it totally, and listens attentively till the end! This is how it goes...

A-for-Apple and B-for-Ball were going for a walk. There they met C-for-Cat and D-for-Dog. A-for-Apple asked C-for-Cat where they were going. C-for-Cat said they were going for an all-animals' meeting and asked if they would also come and witness it. All four started walking.

In some distance, near a river they saw E-for-Elephant. D-for-Dog asked E-for-Elephant if he was coming for the meeting. E-for-Elephant said he was waiting for F-for-Fish.

G-for-Goat was walking in the other direction, and on his head was a H-for-Hat. F-for-Fish asked G-for-Goat where he was going. G-for-Goat said he was going to the shop to get some I-for-Ice Cream and asked if they would accompany him. C-for-Cat said he did not want I-for-Ice Cream, but will instead drink J-for-Juice. As they were eating I-for-Ice cream and drinking J-for-Juice, they saw a K-for-Kite flying high above. At that time, L-for-Lion came there and asked why everybody was looking up. They said they were looking at K-for-Kite.

While they were looking up, they saw M-for-Monkey jumping from one tree to another and they were all wondering  why. When E-for-Elephant asked M-for-Monkey why he was jumping, M-for-Monkey said he saw an N-for-Nest and wanted to know whose it was. O-for-Owl came that way and said that it was her N-for-Nest.

Meanwhile, P-for-Parrot started shouting, "Q-for-Queen has come, Q-for-Queen has come". But it had started to R-for-Rain. So, everyone started hurrying into the S-for-Ship which was waiting there. At the same time, T-for-Train also arrived there. Since R-for-Rain was very heavy, they all opened their U-for-Umbrella and ran into the S-for-Ship and T-for-Train. Q-for-Queen looked at her W-for-Watch and got into her V-for-Van. Since she had a pain in her back, she got in to the V-for-Van to go to the hospital for an X-for-X-ray. In the V-for-Van, while she waited, she ate some Y-for-Yogurt..

Soon, the S-for-Ship and T-for-Train started moving. Just then, they saw an animal running and shouting "stop stop, wait for me!". What was this animal? It was Z-for-Zebra!

Sujit Kumar ChakrabartiTwo Lessons Learned This Year

In my 2011 Balance Sheet Article, I have listed two lessons learned. I wish to explain a bit about them here.

Everything has cost
It's been a long standing issue with me to over-promise myself with too many things to do, and not being able to do many of them eventually. One of the reasons I have identified is my inability to schedule my tasks, i.e. apportion appropriate amount of time to all the intended tasks and then decide when to do them. I have a tendency not to accept that certain things, particularly those which I do not find very interesting or central to my interest, also need time. When we shift from one significant bit of task to another, there are many little things to be done. Take, for instance, the following scenario: I am deep into writing a report at, say, 4.45 PM. At 5 PM, I am supposed be in a meeting in which I am supposed to make a presentation to a remotely located audience. At 4.57 PM, I pull myself out of my reverie and rush to the meeting room. I, then, realise that I need to locate the set of slides to be shared on my computer. The desktop sharing application takes a while to come up. I realise that I also need to locate the conference line number and access code to start the call. When I eventually succeed in locating it, it takes a few number of attempts to establish the call. The projector and network connection also act bratty today. By the time the meeting gets going, it's well past 5.10 PM. Not an insignificant slippage considering that I had a mere half hour slot to present my stuff. Obviously, I rush through my slides, since I had kept ready material worth 40 minutes, and wanted others to know this too. Eventually, when I finish my presentation, not without encroaching into the next slot by a few minutes, I am frizzled and frustrated. No one asks me any question. Not so much much because they had understood everything, as because they are already getting impatient and eager about the next presentation. I missed an opportunity of making an effective presentation, even though I was thorough in my material and preparation.

My undoing was, as you may readily be able to see, in not accounting for the time it takes to wrap one task up and get into another. Preferably, I would have forced myself to close my report writing at some minimal logical point, somewhere around 4.50 PM. That way, I would not only have been physically ready to start my presentation punctually, I would also have felt mentally warmed up for the upcoming activity. That quality implication of the same aren't quite measurable, but definitely significant. The other thing I could have done was to prepare for 20-25 minutes. I could have comfortably glided through my slides, could have had time to take questions, and could have still been left with a couple of minutes for the co-ordinator to facilitate the transition into the next session.

Like in the above scenario, our day to day life is filled with these tasks which we consider as main or bonafide tasks; and there are those we consider as chores, often as distraction. For example, a researcher often considers paper-writing, making presentations, travels etc. as distraction to his main activity of research. The idea of prioritisation underlies this mentality, which is good. However, often it transforms into a wishful thinking wherein we assume that these tasks will somehow be done without our having to do them mindfully. Eventually, we end up allocating insufficient time to them. When we unwillingly get down to do them, the real magnitude and complexity of the task grows upon us like an avalanche. The chore ends up encroaching into the time we had mentally allocated to something more significant.

The biggest loss in such cases is the loss in the quality of the whole experience.
 

The first step towards correcting this habit lies in the topic of this section: to realise that everything has a cost, whether you like it or not. It wise to accept that there are certain activities that must somehow be done, and hence, must also be accounted for in the time budget.

Advantages:


Progress matters more than completion


Another distressing thing related to inability to achieve goals has been that no work ever seems to get over in time unless trivial. Time management principles teach you to break down the work into manageable tiny pieces. Firstly, this task by itself isn't trivial. And secondly, often, the number of these tiny pieces of tasks often starts multiplying like bacteria. In no time they go out of hand. No to-do lists seem to work in such cases. In all such cases, I have found it helpful -- at least in keeping stress down if not in really finishing the work -- to simply decide to progress a bit everytime I sit down to do the task. I try never to think about the end goal in the midst of those sessions. I just concentrate on making a progress.

The biggest advantage of this approach is that it has reduced the resistance to start.

There doesn't seem to be any disadvantage of this thinking. However, it appears that it works well only in cases where the task is such that every bit put into it amounts to a progress. This doesn't encompass the complete set of things we usually do. Particularly, in tasks involving creativity, e.g. research or artwork, which pretty much comprises almost the complete set of things I do, just sitting down to work doesn't mean there will be progress. The most important condition to progress is concentration, which takes time to build. If we break down a job involving 3 hours of work into fragments of half hour each, the number of fragments needed to finish the work would be much larger than 6. In fact, the number may even be infinite. That will be the case with tasks the size of whose atoms is 3 hours, no less. You can't break these activities into anything smaller. The buildup time of concentration in such task could be something like half an hour or an hour. If the individual times are half an hour, you are out of time by the time your concentration builds up. And then you close, and next time you start, you start all over again. It doesn't work!
