i have 3 science classes.
[{"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": "user", "content": "I was sad to hear that Stephen Hawking had passed."}, {"role": "assistant", "content": "Yes he was born 08/01/1942, he was just  76 years old"}, {"role": "user", "content": "He sure lived a long time with whatever his disabling disease was. What is he best known for?"}, {"role": "assistant", "content": "His scientific work was a collaboration with Roger Penrose on gravitational singularity theorems in the framework of general relativity and the theoretical prediction"}, {"role": "user", "content": "Of course! He must have been really smart. "}, {"role": "assistant", "content": "Yes, he sure was. It was shock you to know that he was the first to lay out theory of cosmology"}, {"role": "user", "content": "That is a shock.  Cosmology is a fascinating discipline."}, {"role": "assistant", "content": "He supported any meaningful work of other scientist that relates to quantum mechanics."}, {"role": "user", "content": "Sounds like he really wanted to know how Earth came to be."}, {"role": "assistant", "content": "Yes, he received alot of awards including Honorary Fellow of the Royal Society of Arts (FRSA) including ifetime member of the Pontifical Academy of Sciences and many others"}, {"role": "user", "content": "Thanks! you are very informative"}]
