Limited to the physical level, but with a spirit bright that works at full throttle, Stephen Hawking is one of the greatest scientists of all time. Today is 75 years, despite forecasts of doctors, according to which already should have been dead decades ago. He was recently hospitalized once more, in a hospital in Rome, after a meeting with the Pope.
Hawking is in a wheelchair and, due to a tracheotomy, unable to speak from some 30 years ago. However, that does not prevent him to travel around the world, always accompanied by a group of people among his nurses.
The scientist, who lives in London, suffers from amyotrophic lateral sclerosis, a neuromuscular disease that has no cure. From decades ago that you can hardly move. Can only be understood with the aid of a computer.
Hawking became ill when I was a student of physics. The disease progressed and marked a turning point in his life. “I suddenly realized that there were a number of valuable things I could do if I was given a chance,” he mused. With great ambition and keen intelligence, he managed to come out ahead. In 1979 he became a professor of mathematics at Cambridge, where he was proprietor of the famous chair Lucasian of Mathematics for 30 years.
Hawking impressed the academy with his theories on the origin of the cosmos and black holes. “I want to understand the universe completely,” he said. “I want to know why this is so, and why does it exist in reality”, he revealed. His book “a Brief history of time” also became popular among the public, non-expert.
The black holes not are terminal stations, although they absorb everything they are about through their huge force of gravity, even light. But Hawking was able to prove in the theory that black holes evaporate slowly, a consequence of quantum physics. As the evaporation occurs over an extremely long time, yet failed to check the call Hawking radiation.
as phd student in 1965, along with the british Roger Penrose, Hawking provided an important mathematical proof for the Big Bang theory. The idea of the Big Bang was still very discussed, among other things because it is not governed by the laws of nature, and because it seemed necessary to consider some type of creation.
Hawking also worked on the general theory of relativity of Albert Einstein. She was able to demonstrate that predicted a beginning of the Universe, a result that was interested in the Church, as he wrote in his autobiography, “a Brief history of my life”. Later, however, he stressed that the beginning of the Universe did not necessarily had to be placed in a singularity such.
what Hawking owes his fame only to his theories? According to him, there is something more: “I Am the epitome of a genius disabled,” said the chain BBC. “People are fascinated by the contradiction between my corporal capacities are extremely limited, and the enormous dimensions of the Universe to which I devote myself,” he said.
Popstar
Hawking is a kind of popstar of science, who does not hesitate to take a stance on popular topics such as time travel and aliens. In the last few years was very critical and warned that the Earth may be threatened by intelligent robots, global warming, nuclear war, and the virus produced by genetic techniques.
Your message is that humanity must find alternatives in the Universe facing the possibility of a disaster on Earth. Along with the multimillionaire Russian Juri Milner plans to send out an Army of space ships to a journey of exploration of 20 years for the Alpha Centauri star system. “Sooner or later we have to look at the stars,” he said.
despite his job, also can dedicate to his private life. Hawking married twice and has three children. He was married to the love of his youth, but finally parted. Later, his ex-wife said he was like a tyrant. “The glory pulled out of orbit of our family,” said she.
In 1995 Hawking married his nurse, in a marriage that lasted 11 years. In an interview with New Scientist magazine, when asked what he thought about mostly every day, he replied: “Women. They are a true enigma.”
