	Hawking gained his most popularity in 1974 with his breakthrough research. He demonstrated that matter, in the form of radiation (called Hawking radiation), can escape the gravitational force of a collapsed star, contrary to the belief that black holes are information vacuums. Hawking radiation reduces the mass and energy of black holes and is therefore also known as black hole evaporation. Therefore, black holes that lose more mass than they gain shrink and eventually disappear.		Hawking gained his most popularity in 1974 with his breakthrough research.

	Hawking attended University College, Oxford for his undergraduate education, where he completed a degree in Physics. Contrary to what most would believe, Hawking slacked his three years at Oxford, claiming he probably devoted about a thousand hours to his studies during his three years at Oxford. He found the academic work very easy, and refused to answer exam questions that tested factual knowledge rather answering only those that dealt with theoretical physics. He barely made first class honors in Oxford, which he needed in order to continue to his graduate studies in cosmology at the University of Cambridge. In a critical oral exam, Hawking told his examiners that "If you award me a First, I will go to Cambridge. If I receive a Second, I shall stay in Oxford, so I expect you will give me a First." and his examiners realized that Hawking was far more clever than any of them.

	Hawking had a rough start at Cambridge. During his time at Cambridge, he was diagnosed with ALS and felt depressed for a period of time. He was, however, motivated by his supervisor Dennis William Sciama to continue his studies, and he did so very brashly. Physicist at the time debated about the prevailing theories on the creation of the universe, specifically the Big Bang and Steady State theories. Hawking wrote his thesis inspired by Roger Penrose's theorem of a spacetime singularity in the center of black holes, and applied this thinking to the entire universe. Hawking attained his ~~PhD~~ degree in cosmology in 1966, titling his Adams Prize winning essay "Singularities and the Geometry of Space-Time."		Hawking had a rough start at Cambridge.

	~~===Contributions to physics===~~		After gaining his Ph.D., Hawking became a Research Fellow and then a Professorial Fellow at Gonville and Caius College in the Institute of Astronomy. He left this department in 1973 and worked in the Department of Applied Mathematics and Theoretical Physics as Lucasian Professor of Mathematics from 1979 until 2009. This chair was held first by Isaac Barrow and then in 1669 by Isaac Newton. Hawking is still an active member at the University of Cambridge, currently retaining an office in the Department of Applied Maths and Theoretical Physics. His title is now the Dennis Stanton Avery and Sally Tsui Wong-Avery Director of Research at the Department of Applied Mathematics and Theoretical Physics.
