Hey Jaydeep,
Guess more people have heard of it than you think. I am aged 20 and i have also heard of it. Though im not from a science background, (Commerce & Business, im going to graduate from BMS - Bachelor Of Management Studies) i love intellectual topics like quantum physics and so on. It stimulates the grey cells and is of immense interest to me.
The funny part is, by co-incidence on this thread, ive always hated chemistry. I had taken up science in the 9th & 10th and was very very bad at chemistry as nor would it interest me and hated mugging the formulas. Was pretty bad at it but luckily always just about managed to pass. Found biology and physics pretty easy to cope up with. Finally, in the ICSE board exams after 10th, i passed in science with good marks.
I believe a basic knowledge of science, the type given to you in 9th & 10th, is a must for anyone and everyone. Helps you a lot to understand things in life later on.
Oops, sorry for hijacking and making it all about me

Coming back to the topic, i heard about String theory and lots more through this wonderful series by BBC. It is called BBC Horizon. My best friend is doing engineering and he introduced me to all this. Poor chap is studying in Durgapur though we live in Mumbai. The series is very well presented and makes it very easy for the layman to understand all this. Not to mention fantastic editing and discussions.
Particularly loved the part about gravity in string theory wherein it is observed that we are not losing gravity to another dimension but rather gravity itself is leaking into our dimension!!! Else we would not have gravity!!! Crazy stuff.
I also love the topic of 7 intelligences by Gartner. Absolutely fantastic.
I think ill leave the discussion at that and perhaps we can continue it in a thread created by you later on or something

Cheers to joining this wonderful forum.
Now let me see how i can help you, am heading to your thread right away.
EDIT: Also just saw your profile and realised you are interested in Mac OS X. Fantastic, we will get along pretty well. Love Leopard and im using it right now. I think Mac OS X is light years ahead of windows in terms of usability, reliability and creativity. An added bonus is the design of the hardware of all apple products. Almost forgot to mention how much more productive it is than windows. I dont hate windows, but in comparisn, ....what comparisn...haha. Point proven when Vista was launched which is just a copy of Mac features integrated into windows.
