I do not have much credentials to talk about his
achievements, which are a matter of fact huge and
undescribable.The name itself is able to convey a lot
to the minds of people who know him even a little.
There is an official site which describes his
itinerary over a certain period of time.There are
lots
of books available about his achievements
and the one I found most interesting is the
one named "A Brief History of Time".
He is at present on a post which was once held
by one of the greatest scientist of the pervious
chiliad.That post is called "The Lucasian Chair".
If you want to know more about him and his works
