Apologies for such a large gap in posts. I had some logging in problems, then SATS preparation came up, and before you know it, you fall out of the habit. But this needed to be posted.
Professor Stephen Hawking CH CBE FRS FRSA (8 January 1942 – 14 March 2018) is probably the man most of you know as the scientist in the wheelchair with the robot voice who you have seen on tv shows like the Big Bang Theory. He was one of Britain's foremost cosmologists and theoretical physicists, and produced a number of theories about the nature of the universe, and black holes, which have revolutionised our understanding of the history of our universe. His book, A Brief History of Time, took the ideas and explained them in language that non-mathematicians could understand. It sold 10 million copies and was translated into 35 languages. In it he explains numerous things, including his ideas on how to unite what seem to be two opposing theories on how everything works: Relativity and Quantum Mechanics.
By the age of 21, Hawking had been diagnosed with a progressive disease with no cure, Lou Gehrig’s disease, and doctors gave him two years to live. Despite this, and despite losing his voice, Hawking, with a lot of support from various sources including his family, defied the predictions and lived for another 55 years. He never stopped working, his last paper being published days before his death.
