Bought a book to read today about Stephen Hawking, ever heard of him?
The English theoretical physicist, cosmologist, author and Director of Research at the Centre for Theoretical Cosmology?
Yes that is him, I have not read the book yet what can you tell me about him?
He was born on the same day as my grandfather 8 of January 1942.
Oh that is cool, he was brilliant was he not?
Some think so. I'm not one of those. His theory's on Cosmology are not up to snuff with others. 
Really? Tell me more about that.
