Stephen Hawking is perhaps the most well know theoretical physicist in the history of the world, meaning that he’s one of the only two theoretical physicists most people outside of STEM fields can name. He’s the author of “A Brief History of Time,” which is one of the most highly regarded and well known works ever written on The Big Bang Theory. When he was just 12, he was diagnosed with amyotrophic lateral sclerosis (ALS), a disease which most people die of within 5 years. However, Professor Hawking is currently in his 70’s. He moves around and communicates via a specialized wheelchair which includes a voice synthesizer. His IQ is 160.
