Stephen hawking biography resumidas

Stephen William Hawking 8 January — 14 March was an English theoretical physicist , cosmologist , and author who was director of research at the Centre for Theoretical Cosmology at the University of Cambridge. Hawking was born in Oxford into a family of physicians. In October , at the age of 17, he began his university education at University College, Oxford , where he received a first-class BA degree in physics.

In October , he began his graduate work at Trinity Hall, Cambridge , where, in March , he obtained his PhD in applied mathematics and theoretical physics, specialising in general relativity and cosmology. In , at age 21, Hawking was diagnosed with an early-onset slow-progressing form of motor neurone disease that gradually, over decades, paralysed him.

Hawking's scientific works included 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.

Initially, Hawking radiation was controversial. By the late s, and following the publication of further research, the discovery was widely accepted as a major breakthrough in theoretical physics. Hawking was the first to set out a theory of cosmology explained by a union of the general theory of relativity and quantum mechanics. Hawking was a vigorous supporter of the many-worlds interpretation of quantum mechanics.

Hawking achieved commercial success with several works of popular science in which he discussed his theories and cosmology in general. Hawking was a Fellow of the Royal Society , a lifetime member of the Pontifical Academy of Sciences , and a recipient of the Presidential Medal of Freedom , the highest civilian award in the United States. He died in at the age of 76, having lived more than 50 years following his diagnosis of motor neurone disease.

In , when Hawking's father became head of the division of parasitology at the National Institute for Medical Research , the family moved to St Albans , Hertfordshire. He later blamed its " progressive methods " for his failure to learn to read while at the school.
