Physicist Stephen Hawking Dies

Noted physicist and author, Stephen Hawking died Wednesday March 13th 2018, he was 76.  According to his family he died peacefully at his home in Cambridge in the United Kingdom, as the result of complications of amyotrophic lateral sclerosis. Dr. Hawking was best known for his work in cosmology, specifically black holes and relativity and for authoring the hugely successful science book, "A Brief History of Time." 

Dr. Hawking was diagnosed with ALS, also known as Lou Gehrig's disease, when he was 22. Progression of the motor neurone disease eventually left Dr. Hawking confined to a wheelchair and unable to speak. He did not however let that stop him from making significant contributions to science. When he was a graduate student at Cambridge University he and Roger Penrose of Berkbeck College of London were able to prove mathematically that black holes actually exist.

He later theorized the existence of mini proton sized black holes that he believed eventually evaporated. He then concluded that this meant that these black holes were essentially radiating away through what has become known as Hawking Radiation. A few years later, with the help of Dr, James Hartle form the University of California Santa Barbara, Dr. Hawking arrived at the assessment that our universe was a closed system and therefore is boundless like the Earth. 

In the late 1980's, Dr. Hawking achieved real stardom when he wrote the science book, "A Brief History of Time." His book stayed on the Sunday Times best seller list for 237 weeks which won it a place in the Guinness Book of Records. Dr, Hawking won the Einstein Award, the Wolf Prize, the Copley Medal, and the Fundamental Physics Prize. In 2009, he received the Presidential Medal of Freedom. In 2014 His life was made into a movie named, "The Theory of Everything," which won an Academy Award for Eddie Redmayne, the actor who portrayed him.
