I would like to tell you about Steven Hawking. He was born in England 8 01 1942. Both his parents had studied at Oxford. Both his parents had studied at Oxford. When he was 21, Stephen started tripping, dropping items and his speech became unclear. After a series of tests, doctors concluded that Stephen was suffering from ALS- Amyotrophic Lateral Sclerosis; a disease which paralyzed him and required a speech generating device to communicate. His most famous theory is that black holes can emit radiation; also known as Hawking radiation. Hawking has received numerous awards but never won the Nobel Prize. To my mind, it is so sad. I think, he made lots useful invention.
