From Edison’s diary
Thomas Alva Edison was one of the greatest inventors we know about. Sometime ago, I stumbled upon a book titled THE DIARY AND OBSERVATIONS OF THOMAS ALVA EDISON, and was an interesting read. In there we obtain an insight to Edison’s view on many different subjects including education, work, religion etc. Edison was a person with strong views. His working methods were unconventional. Here are a few interesting facts I learnt from this book:
1) Edison had to recruit many executives to his labs; he always emphasized on a memory test and gave them a questionnaire to answer. He insisted that memory is very important for decision making, and he usually employed those people who had very good memory. Edison wrote “…Certainly the brain should have the facts. If a brain possesses an enormous number of facts, those facts, through action of the subconscious mind, will automatically keep themselves available when needed and will automatically keep themselves out of the way, not interfering when not required.”
2) Edison’s view on education was interesting and bold for his times, and he believed that learning through movies would be vital for future education. As early as 1890s, he said that best way to teach geography is either by taking the student on a tour or to show them a movie. Edison wrote “…motion pictures can be applied to a scientific, systematic course of memory training in the schools, taking the children at an early age when the mind is plastic enough to adapt itself most readily to new habit of thought.
Most of our text books fail on two big counts. They are not sufficiently human, and their application is not sufficiently practical”
3) In the following lines Edison gives an insight to how he worked: “When I want to discover something, I begin by reading up everything that has been done along that line in the past-that’s what all these books in the library are for. I see what has been accomplished at great labor and expense in the past. I gather the data of many thousads of experiments as a starting point, and then I make thousads more.”
“ …..The motive that I have for inventing is, I guess, like the motive of the billiard player, who always wants to do a little better-to add to his record. Under present conditions I use the reasonable profit which I derive from one invention to make experiments looking towards another invention…..”
4) Edison rates phonograph as his greatest discovery. He writes “Which do I consider my greatest invention ? Well, my reply to that would be that I like the phonograph best. Doubtless this is because I love music. And then it has brought so much joy into millions of homes all over this country, and , indeed, all over the world.”
5) The following quotation by Joshua Reynolds was hung in every room of Edison’s laboratory “ There is no expedient to which a man will not resort to avoid the real labor of thinking”
There are many more fascinating thoughts of Edison, many agreeable and a few disagreeable ones, in the above mentioned book, and if you happen to find it, read it through…it’s a classic autobiography.

Sailing against the wind
John Petit-Senn told “True courage is like a kite, a contrary wind raises it higher”. To have a firm belief in something and to pursue it courageously till the end is one of the finest human qualities. This quality was exemplified by Daniel Shechtman, who recently won the Nobel prize in chemistry for the discovery of quasicrystals. According to conventional knowledge of crystallography, crystals can exist with certain symmetries only. So the convention was that crystals in nature can have only 1-, 2-, 3-, 4- or 6-fold rotational symmetry, with everything else not allowed. Contrary to this, Daniel discovered that there exist crystals whose rotational symmetry is 10 fold. When he announced this discovery, he was mocked and humiliated, and was asked to leave his sabbatical research group. Great scientists including Linus Pauling made fun of the discovery on quasicrystals saying “There are no quasicrystals, only quasi-scientist”. However, Daniel pursued his research and submitted it to Journal of Applied Physics, but was rejected. Yet he persuaded his colleagues in different countries to verify his discovery and finally his paper was published in Physical Review letters. This speaks of Daniel’s character of persistence and how he believed in his observations and finally triumphed. Nowadays everybody approves of quasicrystal’s existence, and Nobel prize is a fair indicator.
[A word of caution: all great research will not fetch the Nobel prize, and some of the deserving scientist may have been omitted in the past for various reasons. Who gets this prize, they usually deserves it, but the one who misses it should not be forgotten.]
What is related to this matter of persistence is that there have been plenty of scientific discoveries in the past that was initially rejected by the scientific community, but later went on to win the Nobel prize. A search on internet resulted in an interesting paper by a Spanish researcher named JUAN MIGUEL CAMPANARIO who wrote on Rejecting and resisting Nobel class discoveries: accounts by Nobel Laureates, in Scientometrics, Vol. 81, No. 2 (2009) 549–565. There he notes how more than 20 discoveries which were rejected ina journal were later accepted either in a different journal or in the same journal, and further went on to win the Nobel prize.
So the next time when you make a discovery and if somebody rejects it, you know what to do !

The problem of excess
Somebody unknown wrote: give a person a fish and you feed them for a day; teach that person to use the Internet and they won't bother you for weeks. In the current age roti, kapada aur makhan has a new companion: information. Information has become integral part of our lives, and we have devised many mechanisms to obtain them. In 90s and early 2000s, we saw revolution is terms of internet and satellite technology, as we amassed various methods to obtain quick information. But now we live in age where there is an overload of information. This overload of information is a problem of excess, and many of us will have to think deeply about its consequences.
Information overload has many outcomes. One of them is multitasking. We tend to tackle many different issues at a given period of time by dividing our attention to various tasks at hand. We will have to introspect about this division of attention. Researchers at Stanford University have looked into the concept of social media multitasking and it consequence on cognitive control (PNAS paper), and their results show that attention-to-detail decreases as multitasking increases. This is obvious because the average time that one spends on each task is reduced, and the continuity of thought is interrupted every time one switches task. This can be easily evidenced when we browse on the internet. Just observe how many tabs are open in your window, this a fair indication of how your attention is divided between tasks. Another assessment you could make is to check how many times you log-in to your e-mail. You will be surprised that one does this more than the required number. Why do we do this? After all, e-mail gives us the freedom of access at our own will, but even then we sometimes over use it.
What is further surprising about the Stanford study is that it shows that heavy-multitaskers tend to be more susceptible to interference from irrelevant information. This is indeed a cause for concern as our decision making can be affected due to multitasking.
Now the important question is how do you overcome the problem of information overload? First thing is to acknowledge that we cannot stop the inflow of information, so the choice at our hand is to filter the incoming information carefully. We will have to somehow set priority on the basis of importance and interest, and stick to one task at a time. In this context let me give 2 examples of great minds:
1) Isaac Newton was asked how he could successfully solve so many scientific problems. His answer was that he paid patient attention to the problem at hand and thought about it for long periods of time. Some of his contemporaries have mentioned that Newton could think about a problem not for hours or days but for months. Such unperturbed attention is indeed hard to achieve, especially in the present context, but it is indeed fascinating to learn that Newton had this remarkable capability.
2) Henry Poincare, who was one of the greatest mathematicians, describes in detail about his mathematical creativity, and in there he mentions that a conscious unsuccessful effort to solve a problem is usually followed by a unconscious effort by his brain, and this unconscious effort further leads to an answer that one was seeking while working consciously. For this unconscious effort to perform well, we need to put-in concentrated effort during the conscious effort, and this can happen only when we perform a single task at a time.
The above two examples give an overview of how deep, unperturbed thinking has interesting consequences, and also indicates that one thing at a time is indeed far more productive than multitasking.
It is an intriguing situation we live in today. Around 20 years ago people were struggling hard to obtain information, and the most powerful people were the ones who had the information. Now we are in a more democratic situation where information is just a matter of a mouse click but we struggle hard to discriminate the intellectual wheat from the chaff. The problem of excess is here to stay, it is up to us make a choice whether we want to multi-task or multiply our effort on each task.
There is a short, funny movie made by XEROX on Information Overload Syndrome: you may want to watch it.

Facts in Fiction
To
My African Friend
Developing country
My Dear Friend,
Greetings from India ! I hope you and your family is doing well. It was heartening to get your letter, and your words conveyed your well-being, and I am glad to learn that. It’s been quite a long time, in fact 5 years, since we have met each other. Our first, and the only meeting was on a train journey from Bangalore to Delhi, but I am happy that our friendship and the intellectual conversations has been active through mails. I understand from your previous letter, that you are writing a book, and you wanted to know some specific things about India. This letter is an attempt to unveil few of my thoughts on 3 issues you had asked for. Please remember that what I write here are my own views, and my words vary from being accurate to inadequate to mere speculation. I leave it to you to make the judgment. So here are some of my thoughts.
India vs China
This comparison has been done all over the world, but I think it is an unfair comparison. Specifically, the rate of technological growth in China is far superior to India. This is partly due to the pace at which we work. Our decision making bodies take quite a looooooooooooooooooooong time to come to conclusions. In fact, it is so long that even to install a security camera in Delhi high court, we took more than 3 years, and I am not sure whether the cameras are working or not. So if you think that we are head and shoulders with China in development, then my friend, you are under a wrong impression. China has its own problem – some are simple and some difficult ones to solve, but atleast they are trying. In India we are fighting our enemies within and it will take a while to wake up. If you look at India and China as an outsider, you will always see that China will be leading for next 20 years, at the least. My prediction is that our development gap will widen in future. In general, an argumentative Indian is a sheer joy to watch, but you ask the same guy to execute what he has argued upon, he will fail miserably. Execution of thought is the burning problem of India. We have great minds and very ordinary hands. After all, empty vessels make more noise, and our political class is a vessel of infinite volume.
Indian media and entertainment
Hey, you liked food with lots of masala, isn’t it? well, this aspect is typical of Indian food. Our media and entertainment has taken this concept too seriously and have adapted this into their working. There is a huge difference between substance and image, and our news and films are mainly run by images but not by substance. This does not mean we lack the right people, but it means that wrong people are on the right camera. You will observe that stupid films made by egomaniac, animal killing, drug-addicted actors will make box office hits, and deep, thought provoking, low-budget movies made by some talented people will hardly make a mark on the media, leave aside the people. I have a strong feeling that most of the movie directors in Indian cinema have miserably failed in their basic science classes in the school. They show many unphysical things in theirs movies, that a pool of fans think that physics is a joke, and Indian movie is a reality. I fear for their mental stability and I seriously wish that our government build more mental hospitals for them. Coming to the advertisements in our media, you must see some of the “Fair and nonsense” brands that go around the circuit. If you think we are not racist after seeing these ads, then you are deceiving yourself. It’s dripping in our society. There are many regional news channels which cover and recover news day and night. They go to every nook and corner of India and report anything which can be detected on the CCD of the camera. If you think India has given great freedom to its news media, then you are right. Right because our news media can covers anything on earth including the fictious news.
Sports
Cricket : 99.999999% :: other sports : ~ 0
We are obsessed with cricket. We like it and sometimes take it very seriously. We have a very famous team of cricketers, who are richer than some of your African kings. Few are great. Many of them are good cricketers in Indian conditions, and not so good when they travel. This team is usually coached by a guy who will not make them work very hard. If the coach tries to do so, our captains and media will annihilate him. Now the recent trend in Indian cricket is to couple itself with our film industry (bollywood), and make a lot of noise in a tournament called Indian Premier League (IPL). It is a league played by the cricketers, run by the jokers, feasted by the pokers and funded by liquors. Other sports hardly fill a part of the final pages of newspapers. Actually field hockey is our national game, but it is so poorly administered that someday the players may use their hockey sticks to play cash rich cricket with bollywood funds. There are many willing sports persons in our country, and some of them have made their mark in international circuit, be it chess, shooting, despite the hardships they face.
All the above are tiny insights to the great Indian tamasha. We are still “work in progress” mode, and I hope to update you in future. Meanwhile, you may explore more on the web, and don’t watch too many bollywood movies in Africa. I know you like it, but you may have to re-learn your physics from scratch. Beware !
This is all I have for this letter, I hope this will help.

A Wonder called Work
George Bernard Shaw said “When I was young, I observed that nine out of ten things I did were failures. So I did ten times more work.” Yes, it’s plain and simple : MORE WORK. Time and again, we have seen that ordinary people, with the philosophy of doing ‘more work’, flourishing in their deeds. Let me sight some examples. Approximately 10 years ago, I had the privilege to visit ISRO and see the construction of the satellite INSAT 3C from close quarters. I learnt that most of the scientists working on the satellite were from humble background with conventional education from universities of India, not from IITs. What I also learnt is that they worked with a philosophy that systematic thinking and hard work (~12 hrs/day) was more important than sophistication and style. We all owe a lot to them because the communication systems, be it mobile phones, or satellite television or any other hi-fi stuff we use in India is due to these hard working people. Over the years, my research career has given me an opportunity to work with various researchers across the globe. I was impressed to observe a professor who had a limited background and was rated average in a particular research field, but through sheer hard work, he accomplished so much over the years that even the experts in the research field were found wanting in comparison to his work. While I observed all this, I read an interesting book TALENT IS OVERRATED. Written by Geoff Colvin- the editor-in-large of Fortune magazine, this well researched book shows that extra-ordinary effort by ordinary people can accomplish some wonderful things. The author notes that excellence come from deliberate practice, and deliberate practice is not just practice for long hours, but a practice with vision for accomplishment. There are many anecdotes and references in the book which substantiates these claims. It’s worth a read as one can adapt many things into their life by understanding work is more important that talent.
India is undergoing a change. The middle class society, especially the younger lot, is seeking an external change in terms of politics and many other things, which is heartening. But in a youthful world of instant messages and fast-food mentality, hard work and patience is compromised by the majority of the youth in this country. It is high time that we seek not only an external change but also an internal one. Then most accomplishments we intend to achieve are only a matter of time and EFFORT. After all, hard work pays off.

A transition to understand
The altitude one scales in life is propelled by aptitude and sustained by attitude. Aspiration, desire and commitment are easy to say, but difficult to practice, as it requires tremendous amount of self-discipline. I have been observing that children, in general, have this remarkable character of being disciplined, and can learn things at a faster rate than adults. In recent days, two things have caught my attention in the context of the above discussion:
1) The SUPER30 organization in Patna, which hunts for 30 meritorious talents from among the economically backward sections of the society and shapes them for India's most hyped-up examination of IIT-JEE. In the last seven years, it seems it has produced hundreds of IITians from extremely poor background. Hats off to Anand Kumar who is running this organization, and hats off to the students from poor background who are cracking the JEE. Although, I don’t endorse these rat-race examinations, I admire people who take up the challenge to write this examination and get through it successfully. It’s a hard task, I must admit. If you observe many students coming out of this organization, they are extremely hard working with a sustained frame of mind to achieve a goal. Indeed, they inspire me.
2) The other thing in the same context is the reality-shows on television that showcases talent of Indian children. Some children do remarkable things (including dance, singing etc.). Probably, parents' encouragement is vital in this, but children put up a show with an air of enthusiasm, confidence and commitment, which one can hardly see in the grownups.
I have not yet found an answer to the following questions:
Is it difficult to learn something new as you grow older or is it just a matter of attitude?What is really happening to the attitude when there is a transition from adolescence to adulthood?
Just think about a situation when adults start working as well as they would have done during their childhood, that can make a lot of difference. maybe it is time for us to grow our minds younger, perhaps, like the intellectual case of Benjamin Button.

On the slower lane…
To learn we need information. Our thinking is vastly influenced by what we are informed of, and when we are fed with a large pool of information, gaining accurate knowledge is not trivial. Since last decade or so, communication and information retrieval have been revolutionized by internet. Now we are in situation where there is an excess of information, and the major task is how to find the required knowledge from a large pool of information. There may be more and more accurate search engines which can filter and narrow down your query, but the major question is how does your mind differentiate between accurate information from the inaccurate one?
Perhaps, the answer lies in spending more time on the information we acquire, and here lies the major problem. There is a conflict in our mind, where our thinking has to be adapted to the rate at which the information flows in. As a result of this, we need to think faster, learn faster and decide faster to keep up the pace. This implies that the average time on thinking, learning and decision making is now proportional to the rate of information flow. But from previous experience and history, we very well know that accuracy in thinking, learning and decision making critically depends on the amount of time we spend on it. It is as simple as this: longer the time we spend with data, more information can be retrieved out of it. But now, we are in a situation where we need to hasten the processing time. So, the problem is: how does one acquire accurate knowledge by keeping pace with the rate of input of information?
May be, to improve our ability to judge and prioritize, we need to slow down our lives. Yes, SLOOOOW DOWN…. Rushing through may be a requirement of our environment, but going on a slower lane gives us opportunity to foresee a mistake which we may make by going faster. A deeper and longer thought on this issue is required URGENTLY!

Pavan2.0
It’s been quite a while since I have written a blog. Married life and a new job @ new place are good excuses for that.
Life in Pune has been decent; it’s a new environment for me and we are slowly adapting to it. The city is very hilly, fairly industrialized, flooded with students, and people are friendly. The cost of living is high, but a variety of food is available, and weather is warmer than west Lafayette, Barcelona and Bengaluru, but the nights are very similar to Bengaluru. The local city transport (bus and auto) is bad, which gives you a good reason to buy a vehicle (now I have a cycle but may graduate to a motor!)
Job-wise, the transformation from a post-doc to an assistant prof. has been really exciting. Now that I am in an institute where the emphasis is not only on research, but also on teaching, the prospects for innovation and creativity are high. Come this August, I will be part of biophysics course, which is essentially an interdisciplinary subject (reflecting our institute's agenda). I would also lecture in an advanced laboratory course of physics/physical chemistry. Since the semester has not yet begun, I haven’t interacted much with the students, but whomsoever I have spoken to are excited to be part of science, and this is indeed a pleasant thing. Most of the faculties are young, knowledgeable and dynamic, and all of them believe that they can make a difference by incorporating research with teaching into their work. This is a new experiment in Indian science, and we are really excited to be part of this. More in coming weeks…..

Mahatma and the Valentine
Anger is an enemy within. This is one part of human nature we can happily mutate. In the backdrop of the recent mishap in Pune, I see the relevance of Gandhiji’s principle of peace growing. Most of the people feel that Gandhism is no more relevant in the present day context. I myself have been conflicting with this conception over the years, but now I have no doubt that Gandhiji idea was an eternal thought of superior quality. The reason why Gandhiji’s peace model ‘seems to be’ out-of-date is because of its difficulty to implement. The idea was seen as irrelevant even during Gandhiji’s contemporary days, just because it needed a huge change in the mindset of human thought. And any change to explore the ‘out-of-comfort’ zone is repelled by us. To reach a level of maturity that the Mahatma attained, it needs sheer commitment, patience, intelligence and above all tremendous amount of inner strength, which are uncommon combinations today. The relevance of a peace model should not only be judged on the difficulty of implementation, but also on the fruitful solution it can bring in, over a long period of time. The greatest way to win over the mind of an opponent is not by seeding a thought of conflict, but by enlightening them by the sheer magnitude of resolve to sustain thought of peace, not just outside, but also within. This idea consumes time, but is and always will be the permanent way to reach equilibrium.
As I write this blog, most of the world is celebrating Valentine’s Day. I welcome any thought which binds people together, and the concept of the day has a positive impact, especially on youth. However, there are now extreme schools of thoughts either opposing or supporting this day. At one end, this day has been well utilized by the corporate world to cash-in on human emotions by hyping this day. On the other end, it has been rejected as un-cultured. The reality is somewhere in between. My thought is the following: Yes, by all means celebrate love, not by restoring to the materialistic rewards of pleasantries, but by ensuring that you not only love your loved ones more, but also love those people whom you hate. After all, this is the bottom line of Mahatma’s thought.

15 lessons of research I learnt
Friday, October 30, 2009
Ponder
Every thought is born in a quest,
a delightful pursuit to understand;
every thought is a peaceful conquest,
guided by the reason’s command.
How I ponder day in and day out,
and try to unveil the nature ?
How I fight this elevated bout,
to construct a thoughtful future ?
Every quest is a clouded mist
where mind penetrates to scatter back;
a mighty thought is a Pascal of fist
entering the fight with a subtle attack.
A great sailing thought has its great equal:
and we adore this as the ‘ocean of labour’;
Latter is the process, former its sequel,
meeting each other at an intellectual harbour.

SKY
Eleven at night,
I look at the heavens;
glitter fills my sight
with angles and demons.
I ask a star,
what’s your kind ?
it twinkles beyond par,
asking me to find.
I sight the Betelgeuse,
the glowing red gaint;
it’s resting at peace
like an elevated saint.
I look out for Sirius,
the queen of white dwarfs;
her looks are mysterious
with electrons as her scarfs.
Now, I search the invisible,
I search the event horizon,
I fail to sight the incredible,
to realize Einstein’s reason.
Should I thank my eye,
for this spectacular show ?
or should I thank the sky
for her ever lasting glow ?

The Rain Dance
I view the water beyond a picket fence,
waiting for the lovely rain to commence;
grayish clouds slowly emerge,
bidding adieu for the sun to submerge.
The river I see is a silky flow,
her surface reflects a silver glow;
trickling rain drops begin the dance,
by writing a poetry on nature’s romance.
Every drop bounces on its back,
as an elliptic pearl with a transparent sac;
gravity pulls the bouncing drop,
to enter the river’s heart right from the top.
Until the clouds and silky river exist,
dance of the rain will continue to persist;
I am a mere spectator of this wonder called ‘rain’,
it awes me to view it time and again.

India vs Europe vs USA
My personal views on research in 3 countries/continents –
Pros:
1) Open source learning, good interaction among students
2) Urge to perform, understand and good awareness
3) People with good theoretical understanding
4) Low cost methods to do high-end research – enriches creativity
Cons:
1) Time consuming, not highly focused
2) Lack of good education in experiments
3) Not many get opportunity to do research
4) Not many are interested in research – ‘software company: big buck’ attitude
Pros:
1) Desire to understand a problem in depth, significant time spent on a problem
2) Research in groups, sharing of knowledge and resources, big projects
3) Technically superior than US and
4) Emphasis on conferences and proceeding
Cons:
1) Sometimes lack of drive and urgency - 9 to 5 attitude
2) Multiple languages
3) Pro-European preferences in positions
4) Hierarchy, high taxes
Pros:
1) Magnificent drive among students and Profs
2) Group meetings – task driven meeting, deadlines etc.
3) Result oriented – ‘come what may we need to do’ attitude, thrust on applications
4) Competition – ‘do it before someone does’ attitude, if you are good, you thrive…
Cons:
1) Money, money, money – it’s a rat race for funding
2) anti open source – capitalistic view point
3) Indian and Chinese students used as cheap labor
4) ‘Black box’ attitude towards instruments
