My meaning of life!

thinking

I have finally finalized [and approved by a committee of 1] my "meaning of life".

1. My wife and kids [upto 18] - live and let them live happy life. No explanation here.
2. Physics/Mathematics - This probably gave me the most happiness in my life. First time when I understood that light is just electro magnetic wave, first time when I could calculate a complicated figure's area with calculus I was simply blown away.

When I read Euclid's abstract geometry it really looked like absolute heaven - no uncertainities, just beautiful theorems, using elegant arguments.

Or when I realized first time, that real numbers are not real after all!

Or when I understood geometry of our space [space-time actually] is not Euclidean [In hindsight even geometry of our earth is not Euclidean]. Or there is nothing like an absolute simultaneity.

Or the weird quantum world which I never could understand so far. Being not a professional in physics, I am never happy with it giving accurate results. It needs to explain, which always bothers me. I learn physics to understand the universe, not to make money or not even for its enormous applications from Satellite TV to nuclear power.

To those who do not know mathematics it is difficult to get across a real feeling as to the beauty, the deepest beauty, of nature ...
-Feynman

3. Biology - Since I am a biological organism and biology really cured me of things like Islam, superstition, God etc. Always I want to understand about this biological marvel called Brain, which can hold a model of the universe inside! Amazing!

Particularly Selfish Gene of Dr. Dawkins really changed my outlook on life and cured me of all superstitions. When I was in 11th/12th in 1995/96 I tried hard to not look at evidence for evolution - Digits of all Mammals, embryos of humans and fish and an overarching one - We all share the fundamental alphabets of genetic information. But only a blind [in thinking that is ]
man can hold out for too long, particularly after reading book like 'Selfish Gene'.

4. Computer science - of course I love my professional field. But here both for its practical applications as well as theorems like Godel's or Turing's.

5. Travel the world with my wife and baby - Travelling is real rejuventor - Whether to Los Angeles or to Goa. That really clears my mind and almost gives me a fresh start!

I don't believe in sugar coated goals like:
1. help others [then what their life is for?] - That doesn't mean I won't help anyone
2. change the world - most of the change the world impacts of individuals are bad - Muhammed, Hitler, Genghis khan, Alexander etc. In the context of whole universe I living in a fleeting moment [1/50000000 of the life of the earth, if I were to live for 100 years ] am too insignificant an event for the universe. In any case as Richard Feynman said 'it is not my responsibility to change the world'

[John] von Neumann gave me an interesting idea: that you don't have to be responsible for the world that you're in. So I have developed a very powerful sense of social irresponsibility as a result of von Neumann's advice. It's made me a very happy man ever since. But it was von Neumann who put the seed in that grew into my active irresponsibility!

3. Live up to others expectations!

You have no responsibility to live up to what other people think you ought to accomplish. I have no responsibility to be like they expect me to be.
Again to quote Feynman!

Computer playing Rock-paper-scissors!

Computers mimic human reasoning by building on simple rules and statistical averages. Test your strategy against the computer in this rock-paper-scissors game illustrating basic artificial intelligence. Choose from two different modes: novice, where the computer learns to play from scratch, and veteran, where the computer pits over 200,000 rounds of previous experience against you.

I managed to beat it reasonably easily. Still interesting ...

to see before you die!



One thing I would say you must see before you die is Giant sequoias like the one here.

It is the photo of Mariposa grove giant which I took when I visited last year. I really felt like It made my life worth something...

Yet another Great doodle!




Google's new doodle eclipses everything


"this doodle not only shows you the moon's movement, but allows you to move a dial as far backwards and forwards as you like in order to observe whichever minute detail takes your fancy."


This is amazing! In fact many of Google's doodles are awesome. Yet another one I love is this, for pacman!

BTW, I learned of this when searching for this article, it is amazing too - Les paul!

Great Rowan Atkinson (Mr.Bean)!



This person is simply amazing! He is real Genius!

I watched a lot of Mr.bean episodes in the past! I am pretty much addicted to them.

Recently I started watching his stand up comedy in youtube - this is Great! It changed my perception of Mr. Atkinson.


See this video - for example:

Lunar eclipse




We watched full lunar eclipse today. It was nice to know and see the red glow of moon [picture courtesy scienceblogs]. We watched about 99% then cloud screwed it up.

BTW, you could see it from google doodle as well! Very nice job from Google.

Dog vision is way worse than ours!

It seems a dog's vision is way worse than a man!

It is 20/75 instead of 20/20. That is what a normal man see at 75 ft can be seen only by dog at 20ft.

I heard this in this talk:
