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.
I tend to believe Michio Kaku and Andrei Linde's theories more. I was a fan of his ollaboration with Roger Penrose on gravitational singularity theorems in the framework of general relativity.
Any supporting evidence of your theory?
"Physics of the Future" (2011), "The Future of the Mind" (2014).
Kaku has hosted several TV specials for the BBC, the Discovery Channel, the History Channel, and the Science Channel.
Early life.
Kaku was born in San Jose, California, to second-generation Japanese-American parents. His father and mother were both born in California; his father was born in Palo Alto, and his mother in Marysville. Both his parents were interned in the Tule
Stephen Hawking
Stephen William Hawking (8 January 1942 – 14 March 2018) was an English theoretical physicist, cosmologist, and author who was director of research at the Centre for Theoretical Cosmology at the University of Cambridge at the time of his death. He was the Lucasian Professor of Mathematics at the University of Cambridge between 1979 and 2009.
His scientific works included a collaboration with Roger Penrose on gravitational singularity theorems in the framework of general relativity and the theoretical prediction that black holes emit radiation, often called Hawking radiation.
