Stephen Hawking

Stephen William Hawking (January 8, 1942 - March 14, 2018) was a theoretical physicist, cosmologist, author, and Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge. 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". Hawking was the first to set out a theory of cosmology explained by a union of general theory of relativity and quantum mechanics. He was a vigorous supppeter of the many-worlds interpretation of quantum mechanics.

The college flag at Cambridge's Gonville and Caius College flew at half-mast, and a book of condolences was signed by students and visitors.
