Physics is like sex!
Today we will talk about a scientist who was an extraordinary man, known as a teacher, lover, master safe cracker (who stole papers of Manhattan Project), fan of Las Vegas’s strip clubs, exceptional liar, musician, artist and probably the most brilliant, influential, and iconoclastic figure in his field in the post-World War II era.

How does one define a role model? A prodigy, hard-worker, achiever, winner in the field one is interested in, right? Well in that case the Nobel Prize winner theoretical Physicist Richard P. Feynman is a perfect candidate as role model to physicists. He was dangerously smart and an exceptional teacher. But underneath everything we generally know about him as a scientist, he had a curios and alarmingly mischievous mind that knew no boundaries.

First let me just mention some of his works:
During World War II Feynman was recruited to serve as a staff member of the U.S. atomic bomb project at Princeton University (1941-42). He was co-awarded the Nobel Prize for Physics in 1965 for his work. Feynman has been credited with pioneering the field of quantum computing and introducing the concept of nanotechnology.

Enough with the facts already! Now lets talk about the wisdom he left behind!

While stealing papers of Nuclear bombing, you should leave mysterious clues: Feynman was a master of desk wiping, lock picking and safe cracking. He even used to think about the mentality and psychology of the safe owner to crack faster. He once cracked three safes of Manhattan project and left certain clues as a mysterious mastermind. Why? Oh just for the fun of course!
If you have to lie, lie with full confidence: It doesn’t matter if what you are saying is absolute truth or not. Even if you are unsure, don’t show it. Just go through it in full throttle judging the situation. Example- Feynman once got on stage and recited a jibrish with just the few words he knew in a foreign language. When one doubtfully asked if it was wrong, he replied that the man didn’t understand the depth of the recital!
If you’re in Vegas and short in money, act as drunk friends of the strippers: I don’t even have the courage and experience to explain this one.
Love what you do and do what you love: In his own words- “Physics is like sex: sure it may give some practical result, but that’s not why we do it.”
Know yourself, find where you belong and embrace your faults: “I learned very early the difference between knowing the name of something and knowing something.”
“That’s the trouble with not being in your own field: You don’t take it seriously.”
“All the time you’re saying to yourself, ‘I could do that, but I won’t,’–which is just another way of saying that you can’t.”

And most important of all- don’t lie to yourself: “The first principle is that you must not fool yourself and you are the easiest person to fool.”

Even after being a dashing lover and romantic husband, Feynman was a phenomenal teacher (yes, this man was everything one wishes to be). His series of books n  The Feynman Lectures on Physicsn is perhaps the most popular physics book ever written which Nature described the book as having “simplicity, beauty, unity … presented with enthusiasm and insight”.

Although he had experimented with LSD and Marijuana just because he was curious about the effects, he was was a damn fine fellow when it came to the meaning and purpose of life. To him the purpose was knowledge as he had described, “I was born not knowing and have had only a little time to change that here and there.”

A boy who knew how radios work, a student who invented his own mathematical symbols for better understanding, an undergraduate who stole a door, the only scientist who watched Atom Bomb test (Trinity test) without wearing glasses, and the only scientist ever who had asked a reporter if he can refuse the Nobel Prize because he didn’t like to answer too many phone calls – Mr. Feynman had lived a life that we live in 4 or 5 lives summed up together. Why? For the glory of knowledge of course! He was an unique personality beyond rules and paths.

Thus like many many other students of physics, if I’m asked about my role model, it is none other than R. P. Feynman- a man who understood very very early that one should focus on understanding instead of just knowing things. Reading about all his life and life’s works one wonders what an honour it would have been to see him once face to face. The man who must have been the only one to appear in the world of Physics with such energy and brilliance.

Read this semi-autobiographic book to experience something like never before.
In his precious word, a person should live a life n  “where you do not feel forced by a need to maintain your position in the organization, or financial support, or so on, to lose your integrity. May you have that freedom.”n

বিজ্ঞানী বলতে আমাদের মাথায় কি আসে প্রথমে? হয় রাশভারী ভারী চশমা পড়া এক আলাভোলা লোক আর নয় পুরাই আউলাঝাউলা এক লোক। কিন্তু পদার্থবিজ্ঞানী রিচার্ড ফিলিপস ফাইনম্যানকে এমন ভাবলে চরম ভুল করবেন।
ফাইনম্যান আমেরিকান বিজ্ঞানী হিসেবে প্রজেক্ট ম্যানহাটনে কাজ করেছেন। যারা জানেন না তাদের জন্য বলি এই প্রজেক্ট পরমাণু বোমা বানানোর সূতিকাগার ছিল। ফাইনম্যান বিজ্ঞানের সবচেয়ে সম্মানজনক পুরষ্কার নোবেলও পেয়েছেন। কিন্তু বিজ্ঞানী হিসেবে উনি ভারী ভারী বইয়ের সাথে এমন বই লিখেছেন যা আমাদের মত নির্বোধ মানুষরাও পড়তে পারবে। ঠিক এমনই একটি বই এটি। বইটার নামকরণও বেশ ইন্টারেস্টিং। প্রিন্সটন ইউনিভার্সিটির একটি প্রোগ্রামে ভার্সিটির প্রেসিডেন্টের বউ উনাকে জিজ্ঞাসা করলেন চায়ের সাথে কি খাবেন, লেবু নাকি ক্রীম? ফাইনম্যান বললেন দুইটাই একসাথে খাবেন। আসলে দুধ চা আর রঙচা যে একসাথে খাওয়া যায়না এটাই উনি জানতেন না। ফাইনম্যানের একথা শুনে ভদ্রমহিলা উত্তর দিলেন Surely You're Joking, Mr. Feynman! ব্যাস, বইয়ের নাম-ই হয়ে গেল এইটা। ফাইনম্যান নিজের জীবনের বিভিন্ন ঘটনা এবং উনার নিজের উপলব্ধিগুলো লিপিবদ্ধ করেছেন। ক্রমানুযায়ী নিজের জীবনের কথাগুলা তিনি বলেন নাই, বরং আগ্রহোদ্দীপক ব্যাপারগুলাতে আলোকিত করেছেন। শেখার জন্য নিজের আবিস্কৃত ফাইনম্যান টেকনিক নিয়ে গল্প করেছে। লোহার ভল্টের সেইফ পাসওয়ার্ড ক্র‍্যাক করা, ড্রামস আর ছবি আকার প্রতি নিজের অদম্য ভালোবাসার বর্ণনা দিয়েছেন। প্রজেক্ট ম্যানহাটনের মূল আবিষ্কার নিয়ে খুব একটা বেশী কিছু বলেন নাই। শুধু মজার ঘটনাগুলাই বলেছেন।
এতকিছুর মধ্যেও কিছু কথা খুব বেশীই মনের মধ্যে লেগে যায়। লাইনগুলা লিখে রেখেছিলাম, তাই নিচে তুলে দিলাম

১. I could do that, but I won’t = I can’t
২. When trying to understand something, keep coming up with examples, and question people about them
৩. Memorizing, or learning things through words, does not equal understanding. Constantly ask yourself, “How can I apply this? What examples can I think of? Where does this apply in the real world?

বেশ ইন্টারেস্টিং একটা বই। শিখতে শিখতে নিজের জীবনকে উপভোগ করেছেন ফাইনম্যান। বইটা একটানে অনেকদুর পড়ে অনেকদিন ফেলে রেখেছিলাম। মাঝখানে খুব বোরিং লাগছিল, অবশেষে শেষ হইল।

I found myself unable to make fair judgement about: Surely You're Joking, Mr. Feynman! Adventures of a Curious Character. One day I gave it three stars and another five. I should think that it certainly deserves five stars in that it is one of the few books that delve into the mind of a genius and gives some idea to their thought process's. My desire to write a review of this book are threefold:

I was stationed in Orlando Florida and it was mandatory that we watch the liftoff's.

After the Challenger shuttle disaster I worked for a woman who did quality assurance for repairs on US Polaris ballistic missile systems who worked with the same seals that failed on the shuttle disaster. Long before the results were published by the investigation team she met Mr. Feynman on a flight to duty stations. In their exchange he asked her what she thought was the problem and told him without a doubt it was the seals.

Reagan the president at the time this disaster had exerted pressure to launch the Challenger in the overly cold weather. I also watched the media's involvement and unneeded sensationalism about the delays that undoubtedly provoked a too hasty decision to launch. I have read many management studies attributing this debacle as a legacy of the decision making process called Groupthink. As this can only be so and knowledge of the affects of cold on the seals was widely know in professional circles and also at NASA it must be surmised that we have a warped decision making system in place in our government.

The lightness that Feynman's stories give to the seriousness of his academic career must only be surmised as a way of dealing with his knowledge of how many problems the Earth is facing in part due to our faulty decision making. It was driven home after watching a video about his life where I was almost brought to tears... The must see video is The Quest For Tannu Tuva[1988] which seemed to be more widely shown in the UK than in the US.

Let's learn from Feynman.

So Nobel Prize winning physicist Richard Feynman was clearly brilliant, but also kind of a jerk. And this was made even worse by the pompous, condescending way the narrator of the audiobook read this book. Honestly, it was a little insufferable.

Whenever Feynman was writing about science, I was all in. But I got so tired. The stories followed one of four arcs: (1) an actually interesting story about something he discovered or how he became a scientist or a science-related thing he did, (2) he has never done x before, but it turns out he was kind of brilliant at it, (3) he, in a playful manner, shows everyone else how stupid and irrational they are, and (4) women are bitches and the best way to get laid is to be a jerk to them. Yeah, I'm totally serious about the fourth.
