Primes are the important main ingredient of numbers, for every number is either a prime or a product of primes.

The concept of zero is attributed to the Hindus. The Hindus were also the first to use zero in the way it is used today.

I don't even possess a car. I ride in auto-rickshaws because I like to be a part of the masses. I don't want to single myself out as someone up and above.

I relax completely when I'm at rest. I don't think of numbers; I don't think of work.
