Guest Star: Stephen Hawking

Stephen Hawking was a noted theoretical physicist, cosmologist, author and professor who worked at the Centre for Theoretical Cosmology within the University of Cambridge. He is known for research into general relativity and quantum gravity, and was an ardent supporter of the "many-worlds interpretation" of quantum mechanics.

Hawking entered the popular consciousness through his best-selling book, A Brief History of Time, and through a number of cameo appearances in popular shows including The Simpsons, Star Trek: The Next Generation, Futurama, and The Big Bang Theory. He used his high profile to campaign for greater support for people with disabilities, and to promote the values of science in public and political spheres.

When Hawking was diagnosed with a rare case of early-onset Amyotrophic Lateral Sclerosis (also known as motor neurone disease or Lou Gehrig's disease) his early twenties, he was only given a few years to live. Hawking triumphed through the disease to research and spread his scientific theories to scientists and the general public alike for another five decades.

Professor Hawking died peacefully in his home in Cambridge on March 14, 2018, at the age of 76.
