Stephen William Hawking CH CBE FRS FRSA (8 January 1942 – 14 March 2018) was an English theoretical physicist, cosmologist, and author, who was director of research at the Centre for Theoretical Cosmology at the University of Cambridge at the time of his death.He was the Lucasian Professor of Mathematics at the University of Cambridge between 1979 and 2009.
Hawking achieved commercial success with several works of popular science in which he discusses his own theories and cosmology in general. His book A Brief History of Time appeared on the British Sunday Times best-seller list for a record-breaking 237 weeks. Hawking was a fellow of the Royal Society (FRS), 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. In 2002, Hawking was ranked number 25 in the BBC's poll of the 100 Greatest Britons.
His 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. Hawking was the first to set out a theory of cosmology explained by a union of the general theory of relativity and quantum mechanics. He was a vigorous supporter of the many-worlds interpretation of quantum mechanics.
Hawking had a rare early-onset slow-progressing form of motor neurone disease (also known as amyotrophic lateral sclerosis "ALS" or Lou Gehrig's disease) that gradually paralysed him over the decades.Even after the loss of his speech, he was still able to communicate through a speech-generating device, initially through use of a hand-held switch, and eventually by using a single cheek muscle. He died on 14 March 2018 at the age of 76.

斯蒂芬·威廉·霍金,英国剑桥大学著名物理学家,20世纪享有国际盛誉的伟人之一,下面是我为你整理的霍金的简介英文版,希望对你有用!
Stephen William Hawking, born in Oxford, England on January 8, 1942, won CH (British Lord of Honor), CBE (British Empire Commander Medal), FRS (Royal Society Member), FRSA (British Royal Art Association members) and other honors. He is a famous physicist at Cambridge University, one of the greatest physicists of modern times and one of the great men of the 20th century.
He suffers from muscular atrophic lateral sclerosis (Luganle's disease), generalized paralysis, can not speak, hand only three fingers can be active.
From 1979 to 2009, he was a professor of mathematics at Lucas. He was the most respected professor in Britain. Hawking's main research field is cosmology and black hole, which proves the singularity theorem and black hole area theorem of general relativity, and puts forward the black hole evaporation theory and the boundless Hawking cosmic model. In the process of unifying the two basic theories of physics in the 20th century, Einstein founded the theory of relativity and Planck's quantum mechanics to create an important step forward.
Stephen William Hawking's research laid the groundwork for today's understanding of the black hole and the origin of the universe, but according to himself, he said that he was in the animated "The Simpsons" and the science fiction episode "Star Trek: Next Generation" (Star Trek: The Next Generation) is also wonderful.
Hawking emphasizes that the universe does not need a Creator or "God" in the "Great Design", "philosophy is dead", which means that mankind will be detached from ignorant self-slavery, denying that pure philosophy and religion can really explain Naturally, it also shows that the major religions are only the ancient spiritual world to explore the unknown, the pursuit of immortal system, rather than the objective truth. With the progress of the times, human civilization is also catch up, not far behind, which is why generations of people of insight to the existence of life and the meaning of the universe. To solve these propositions should have been the task of the philosopher, but unfortunately the highly developed science makes the philosophy can not keep up. Hawking in the "big design" of the opening that "philosophy is dead" is the meaning.
Hawking hopes to solve the mystery of the birth of the universe, the 1970s, Hawking quantum mechanics applied to explain the phenomenon of black hole, in the next 30 years, with quantum mechanics to explain the universe has become more difficult. Hawking wanted to find a set of theories that could explain the universe as a whole to illustrate the birth of the 13.7 billion years of the universe until now, but it has not been concluded for years even if it is infinitely close. According to his theory of quantum mechanics, the birth of the universe is the big bang produced, which is a compressed infinitely small but with large gravity of the material (also can be understood as the density of infinite) explosion products. The theoretical category of quantum mechanics can not explain how this process is going to be done. Why is it so? Hawking says "that must have a theory that can describe small-scale gravity."
The latest scientific breakthrough is Hawking's colleague, Michael Smith of London's Queen Mary's College (Michael. Green) involved in the construction of the superstring theory, referred to as "string theory", which states that all particles and natural forces are actually in shock In the universe like a small object, to solve the Hawking has always wanted to try to answer the gravity problem, this theory must be established in the universe must have 9,10 or even greater than 11 dimensions, and human beings in the three-dimensional world may only One of the real ones of the universe ...
A large number of scientists around the world are doing experiments in space and earth to prove string theory and from experiments to support Hawking's black hole theory and quantum theory. January 24, 2014, the famous British scientist Professor Stephen Hawking once again with its black hole-related theory shocked the physics, in a recently published paper admitted that "black hole does not exist," but "gray hole" indeed exist. In a paper entitled "Information Preservation and Weather Forecasting For Black Holes", Hawking points out that "black holes do not exist" because they can not find the boundaries of black holes. In order to solve the "firewall" problem in the new theory set "black hole does not exist", it does not really do not exist. The black hole of the boundary, also known as the "horizon", the classic black hole theory that the black hole outside the material and radiation can enter the black hole through the horizon, and any material and radiation within the black hole can not wear out horizons.
Hawking's latest "gray hole" theory that material and energy in the black hole trapped after a period of time, will be re-released into the universe. He admitted in his essay that his initial knowledge of the horizon was flawed, and that light could cross the horizon. When the light flies the black hole core, its movement is like a person running on a treadmill, slowly through the outward radiation and shrink. "The classical black hole theory argues that any matter and radiation can not escape the black hole, and quantum mechanics suggests that energy and information can escape from the black hole." Hawking also pointed out that the interpretation of this escape process requires a gravity And other basic forces of successful integration of the theory. In the past hundred years, no one in physics has tried to explain this process.
For Hawking's "gray hole" theory, some scientists expressed approval, it was skeptical. Joseph Polchinski, a theoretical physicist at the Cuban Institute of Theoretical Physics, points out that according to Einstein's theory of gravity, the boundary of the black hole is present, but it differs from the rest of the universe Not obvious. In fact, as early as 2004, Hawking had made a similar statement. On July 21 of that year, Hawking pointed out at the 17th International Symposium on General Theory of Relativity and Gravitation that the Black Hole was not "completely swallowed" around it, as he and most other physicists had previously thought, Some of the information that is sucked into the depths of the black hole may be released at some point.
In 1973, Hawking said he calculated by the conclusion that the black hole in the formation of the process of its quality reduction, but also continue to be in the form of energy to the outside world radiation. This is the famous Hawking radiation theory, the theory mentioned in the black hole radiation does not include the black hole inside the material of any information, once the black hole is concentrated and evaporated disappear, all of which information will disappear, which is the so-called The "black hole paradox". This theory and quantum mechanics of the relevant theories appear contradictory. Because modern quantum physics finds that this material information is never completely gone.
For more than 30 years, Hawking tried to explain this contradictory view with various speculations. Hawking has said that the quantum movement of the black hole is a special case, because the gravity in the black hole is very strong, quantum mechanics at this time is no longer applicable. Hawking's argument does not convince the scientific community of skeptical scholars. It now appears that Hawking finally gave this year's contradictory view of a more convincing answer. Hawking said the black hole never completely shut itself - Hawking radiation, they in a long period of time gradually to the outside world to radiate more and more heat, then the black hole will eventually open themselves and release the material contained in the information.
On August 16, 1616, Jeff Steinhauer, a professor at the Israel Institute of Technology in Haifa, proved the quantum effect of Hawking radiation in a paper published in the journal Nature Physics. He made a sound black hole instead of a light black hole, using a long tube with sound particles, the phonon "horizon". In 2014, Professor Steinhall found that the phonemes were randomly generated in the horizon. In his latest results, Steinhouse proved that these phonons were one of a pair of related phonons, thus proving the quantum effect of Hawking radiation.
April 12, 2016, the famous British physicist Stephen Hawking in New York New World Trade Center Observatory announced a plan called "breakthrough star" plan, with the Russian businessman Yuri Milner, the US social networking site Facebook Founder Zuckerberg collaborated to build a new space exploration project, build a large number of miniature interplanetary spaceships and launch them at half the speed of light to the Centaur Alpha Star. The day was the sixth international manned space day established by the United Nations and the 55th anniversary of the first manned space flight.
Milner said at a press conference that the initial investment in the "Breakthrough Star" program would be $ 100 million to develop a miniature interplanetary spacecraft using laser propulsion and to fly to Centauri in the current generation of time Star of the target.
According to reports, plans to build a miniature interstellar spacecraft called "nano-aircraft", which consists of a "star" computer chip as a hull. Milner at the press conference to show the "star" of the original product. The chip is only two or three centimeters square, a few grams of weight, but integrated camera, photon thruster, navigation and transmission components, is a complete space exploration function of the aircraft, and manufacturing costs only equivalent to an iPhone.
The chip will be installed on the name of "light sail" of the ultra-material cloth Peng, through the ground to launch high-energy laser power to promote, "light sail" can absorb laser energy, driven by micro-spacecraft forward. Because the quality of the spacecraft is very small, there is almost no resistance in space, in the continuous acceleration of the laser, the theoretical calculation shows its speed up to one fifth of the speed of light. If successful, this will allow the spacecraft to arrive near the Earth for about 20 years 4.37 light-year-old Centaurian Alpha Star near. Centaur Alpha Star is one of the closest stars from the solar system, but the existing fastest spacecraft also need to spend 30,000 years to fly there.
"Today, we are determined to take a big step forward in exploring the universe," Hawking said at the press conference, "because we are human beings, longing for flying is our nature.
Chinese experts: Hawking's "spacecraft" is still science fiction

Hawking grew up outside London in an intellectual family. His father was a physician and specialist in tropical diseases; his mother was active in the Liberal Party. He was an awkward schoolboy, but knew from early on that he wanted to study science. He became increasingly skilled in mathematics and in 1958 he and some friends built a primitive computer that actually worked. In 1959 he won a scholarship to Oxford University, where his intellectual capabilities became more noticeable. In 1962 he got his degree with honors and went to Cambridge University to pursue a PhD in cosmology. There he became intrigued with black holes (first proposed by J. Robert Oppenheimer) and "space-time singularities," or events in which the laws of physics seem to break down. After receiving his PhD, he stayed at Cambridge, becoming known even in his 20s for his pioneering ideas and use of Einstein's formulas, as well as his questioning of older, established physicists. In 1968 he joined the staff of the Institute of Astronomy in Cambridge and began to apply the laws of thermodynamics to black holes by means of very complicated mathematics. He published the very technical book, Large Scale Structure of Space-Time but soon afterwards made a startling discovery. It had always been thought that nothing could escape a black hole; Hawking suggested that under certain conditions, a black hole could emit subatomic particles. That is now know as Hawking Radiation. He continued working on the theory of the origin of the universe, and in doing so found ways to link relativity (gravity) with quantum mechanics (the inner workings of atoms). This contributed enormously to what physicists call Grand Unified Theory, a way of explaining, in one equation, all physical matter in the universe. At the remarkably young age of 32, he was named a fellow of the Royal Society. He received the Albert Einstein Award, the most prestigious in theoretical physics. And in 1979, he was appointed Lucasian Professor of Mathematics at Cambridge, the same post held by Sir Isaac Newton 300 years earlier. There he began to question the big bang theory, which by then most had accepted. Perhaps, he suggested, there was never a start and would be no end, but just change -- a constant transition of one "universe" giving way to another through glitches in space-time. All the while, he was digging into exploding black holes, string theory, and the birth of black holes in our own galaxy. In 1988 Hawking wrote A Brief History of Time: From the Big Bang to Black Holes , explaining the evolution of his thinking about the cosmos for a general audience. It became a best-seller of long standing and established his reputation as an accessible genius. He wrote other popular articles and appeared in movies and television. He remains extremely busy, his work hardly slowed by Lou Gehrig's disease (amyotrophic lateral sclerosis, a disease that affects muscle control) for which he uses a wheelchair and speaks through a computer and voice synthesizer.
