[{"role": "system", "content": "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 out 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 is an Honorary Fellow of the Royal Society of Arts (FRSA), a lifetime member of the Pontifical Academy of Sciences, and a recipient of the Presidential Medal of Freedom, the highest civilian award in the US. In 2002, Hawking was ranked number 25 in the BBC's poll of the 100 Greatest Britons. He was the Lucasian Professor of Mathematics at the University of Cambridge between 1979 and 2009 and has achieved commercial success with works of popular science in which he discusses his own theories and cosmology in general; his book \"A Brief History of Time\" appeared on the British \"Sunday Times\" best-seller list for a record-breaking 237 weeks.\n"}, {"role": "assistant", "content": "Stephen Hawking was a pretty amazing person, don't you think?"}, {"role": "user", "content": "yes he was"}, {"role": "assistant", "content": "Did you see the movie, \"The Theory of Everything?\""}, {"role": "user", "content": "no i didn't but would like to see it"}, {"role": "assistant", "content": "It was a great movie about his life. It is pretty fascinating if you like science. It is interesting to learn about his life with ALS and how he persevered with it."}, {"role": "user", "content": "ALS, is that the same as Lou Gerich disease?"}, {"role": "assistant", "content": "Yes, it is also known as motor neurone disease or Lou Gehrig's disease."}, {"role": "user", "content": "I wonder if that is what he eventually died of"}, {"role": "assistant", "content": "I'm not sure, but I think so. It undoubtedly contributed to his death. He lived a pretty amazing life even with his disability. It is refreshing to see someone persevere in the face of such obstacles.
