Words of the Week 39/2015
Stephen William Hawking (born 8 January 1942) is an English theoretical physicist, cosmologist, author and Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge. His scientific works include 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 forth a theory of cosmology explained by a union of the general theory of relativity and quantum mechanics. He is a vigorous supporter of the many-worlds interpretation of quantum mechanics.
Hawking suffers from a rare early-onset, slow-progressing form of amyotrophic lateral sclerosis (ALS), also known as motor neurone disease or Lou Gehrig’s disease, that has gradually paralysed him over the decades. He now communicates using a single cheek muscle attached to a speech-generating device. Hawking married twice and has three children.
