Biografi
Stephen William Hawking is a professor born in oxfrod, Britain, 4 January 1942. He is one of the most famous Physics professors. In his life the professor just sat in a wheelchair due to congenital paralysis. I salute him because for his studies he does not want to be left behind from his normal human being. Examples of examples we deserve.
He succeeded in making a study of quantum. And the theory of cosmology, quantum gravity and black holes. One of his writings is: A Brief History of time
