Read FICTION books online

Reading books fiction Have you ever thought about what fiction is? Probably, such a question may seem surprising: and so everything is clear. Every person throughout his life has to repeatedly create the works he needs for specific purposes - statements, autobiographies, dictations - using not gypsum or clay, not musical notes, not paints, but just a word. At the same time, almost every person will be very surprised if he is told that he thereby created a work of fiction, which is very different from visual art, music and sculpture making. However, everyone understands that a student's essay or dictation is fundamentally different from novels, short stories, news that are created by professional writers. In the works of professionals there is the most important difference - excogitation. But, oddly enough, in a school literature course, you don’t realize the full power of fiction. So using our website in your free time discover fiction for yourself.



Fiction genre suitable for people of all ages. Everyone will find something interesting for themselves. Our electronic library is always at your service. Reading online free books without registration. Nowadays ebooks are convenient and efficient. After all, don’t forget: literature exists and develops largely thanks to readers.
The genre of fiction is interesting to read not only by the process of cognition and the desire to empathize with the fate of the hero, this genre is interesting for the ability to rethink one's own life. Of course the reader may accept the author's point of view or disagree with them, but the reader should understand that the author has done a great job and deserves respect.

Stephen Hawking was born on 8 January 1942 to Dr. Frank Hawking, a research biologist, and Isobel Hawking. He had two younger sisters, Philippa and Mary, and an adopted brother, Edward.[11] Though Hawking's parents were living in North London, they moved to Oxford while his mother was pregnant with Stephen, desiring a safer location for the birth of their first child. (London was under attack at the time by the Luftwaffe.)[12] According to Hawking, a German V-2 missile struck only a few streets away.[13]
Hawking revealed that he did not see much point in obtaining a doctorate if he were to die soon. Hawking later said that the real turning point was his 1965 marriage to Jane Wilde, a language student.[11] After gaining his Ph.D. at Trinity Hall, Stephen became first a Research Fellow, and later on a Professorial Fellow at Gonville and Caius College.

Jane Hawking (née Wilde), Hawking's first wife, cared for him until 1991 when the couple separated, reportedly because of the pressures of fame and his increasing disability. They had three children: Robert (b. 1967), Lucy (b. 1969), and Timothy (b. 1979). Hawking then married his nurse, Elaine Mason (who was previously married to David Mason, the designer of the first version of Hawking's talking computer), in 1995. In October 2006, Hawking filed for divorce from his second wife[49] amid claims by former nurses that she had abused him.[50]

In 1999, Jane Hawking published a memoir, Music to Move the Stars, detailing her own long-term relationship with a family friend whom she later married. Hawking's daughter, Lucy, is a novelist. Their oldest son, Robert, emigrated to the United States, married, and has one child, George Edward Hawking. Reportedly, Hawking and his first family were reconciled in 2007.[51]

Hawking was asked about his IQ in a 2004 newspaper interview, and replied, "I have no idea. People who boast about their I.Q. are losers."[52]
Religious views

Throughout his early work, Hawking used the word "God" in metaphorical meanings but also suggested the existence of God was unnecessary to explain the origin of the universe, as discussed in A Brief History of Time.[53] However, his newest book The Grand Design, as well as interviews with the Telegraph and the Channel 4 documentary Genius of Britain, clarify that he does "not believe in a personal God."[54] Hawking writes, "The question is: is the way the universe began chosen by God for reasons we can't understand, or was it determined by a law of science? I believe the second." Hawking adds, "Because there is a law such as gravity, the Universe can and will create itself from nothing." Graham Farmello of the Telegraph writes, "God did not create the universe, Stephen Hawking revealed."[55][56]

His ex-wife, Jane said during their divorce proceedings that he was an atheist.[57][58] Hawking has stated that he is "not religious in the normal sense" and he believes that "the universe is governed by the laws of science. The laws may have been decreed by God, but God does not intervene to break the laws."[59] Hawking compared religion and science in 2010, saying: "There is a fundamental difference between religion, which is based on authority [imposed dogma, faith], [as opposed to] science, which is based on observation and reason. Science will win because it works."

After Hawking was born, the family moved back to London, where his father headed the division of parasitology at the National Institute for Medical Research.[11] In 1950, Hawking and his family moved to St Albans, Hertfordshire, where he attended St Albans High School for Girls from 1950 to 1953. (At that time, boys could attend the Girls' school until the age of ten.)[14] From the age of eleven, he attended St Albans School, where he was a good, but not exceptional, student.[11] When asked later to name a teacher who had inspired him, Hawking named his mathematics teacher Dikran Tahta.[15] He maintains his connection with the school, giving his name to one of the four houses and to an extracurricular science lecture series. He has visited it to deliver one of the lectures and has also granted a lengthy interview to pupils working on the school magazine, The Albanian.

Hawking was always interested in science.[11] Inspired by his mathematics teacher, he originally wanted to study the subject at university. However, Hawking's father wanted him to apply to University College, Oxford, where his father had attended. As University College did not have a mathematics fellow at that time, it would not accept applications from students who wished to read that discipline. Hawking therefore applied to read natural sciences, in which he gained a scholarship. Once at University College, Hawking specialised in physics.[12] His interests during this time were in thermodynamics, relativity, and quantum mechanics. His physics tutor, Robert Berman, later said in The New York Times Magazine:

It was only necessary for him to know that something could be done, and he could do it without looking to see how other people did it. [...] He didn't have very many books, and he didn't take notes. Of course, his mind was completely different from all of his contemporaries.[11]

Hawking was passing, but his unimpressive study habits[16] resulted in a final examination score on the borderline between first and second class honours, making an "oral examination" necessary. Berman said of the oral examination:

And of course the examiners then were intelligent enough to realize they were talking to someone far more clever than most of themselves.[11]

After receiving his B.A. degree at Oxford in 1962, he stayed to study astronomy. He decided to leave when he found that studying sunspots, which was all the observatory was equipped for, did not appeal to him and that he was more interested in theory than in observation.[11] He left Oxford for Trinity Hall, Cambridge, where he engaged in the study of theoretical astronomy and cosmology.
Career in theoretical physics

Almost as soon as he arrived at Cambridge, he started developing symptoms of amyotrophic lateral sclerosis (ALS, known colloquially in the United States as Lou Gehrig's disease), a type of motor neurone disease which would cost him almost all neuromuscular control. During his first two years at Cambridge, he did not distinguish himself, but, after the disease had stabilised and with the help of his doctoral tutor, Dennis William Sciama, he returned to working on his Ph.D.[11]

Hawking was elected as one of the youngest Fellows of the Royal Society in 1974, was created a Commander of the Order of the British Empire in 1982, and became a Companion of Honour in 1989. Hawking is a member of the Board of Sponsors of the Bulletin of the Atomic Scientists.

Hawking's achievements were made despite the increasing paralysis caused by the ALS. By 1974, he was unable to feed himself or get out of bed. His speech became slurred so that he could be understood only by people who knew him well. In 1985, he caught pneumonia and had to have a tracheotomy, which made him unable to speak at all. A Cambridge scientist built a device that enables Hawking to write onto a computer with small movements of his body, and then have a voice synthesizer speak what he has typed.[17]
Research fields
Hawking in Cambridge

Hawking's principal fields of research are theoretical cosmology and quantum gravity.

In the late 1960s, he and his Cambridge friend and colleague, Roger Penrose, applied a new, complex mathematical model they had created from Albert Einstein's theory of general relativity.[18] This led, in 1970, to Hawking proving the first of many singularity theorems; such theorems provide a set of sufficient conditions for the existence of a gravitational singularity in space-time. This work showed that, far from being mathematical curiosities which appear only in special cases, singularities are a fairly generic feature of general relativity.[19]

He supplied a mathematical proof, along with Brandon Carter, Werner Israel and D. Robinson, of John Wheeler's no-hair theorem – namely, that any black hole is fully described by the three properties of mass, angular momentum, and electric charge.

Hawking also suggested upon analysis of gamma ray emissions that after the Big Bang, primordial mini black holes were formed. With Bardeen and Carter, he proposed the four laws of black hole mechanics, drawing an analogy with thermodynamics. In 1974, he calculated that black holes should thermally create and emit subatomic particles, known today as Bekenstein-Hawking radiation, until they exhaust their energy and evaporate.[20]

In collaboration with Jim Hartle, Hawking developed a model in which the universe had no boundary in space-time, replacing the initial singularity of the classical Big Bang models with a region akin to the North Pole: one cannot travel north of the North Pole, as there is no boundary. While originally the no-boundary proposal predicted a closed universe, discussions with Neil Turok led to the realisation that the no-boundary proposal is also consistent with a universe which is not closed.

Along with Thomas Hertog at CERN, in 2006 Hawking proposed a theory of "top-down cosmology," which says that the universe had no unique initial state, and therefore it is inappropriate for physicists to attempt to formulate a theory that predicts the universe's current configuration from one particular initial state.[21] Top-down cosmology posits that in some sense, the present "selects" the past from a superposition of many possible histories. In doing so, the theory suggests a possible resolution of the fine-tuning question: It is inevitable that we find our universe's present physical constants, as the current universe "selects" only those past histories that led to the present conditions. In this way, top-down cosmology provides an anthropic explanation for why we find ourselves in a universe that allows matter and life, without invoking an ensemble of multiple universes.

Hawking's many other scientific investigations have included the study of quantum cosmology, cosmic inflation, helium production in anisotropic Big Bang universes, large N cosmology, the density matrix of the universe, topology and structure of the universe, baby universes, Yang-Mills instantons and the S matrix, anti de Sitter space, quantum entanglement and entropy, the nature of space and time, including the arrow of time, spacetime foam, string theory, supergravity, Euclidean quantum gravity, the gravitational Hamiltonian, Brans-Dicke and Hoyle-Narlikar theories of gravitation, gravitational radiation, and wormholes.

At a George Washington University lecture in honour of NASA's fiftieth anniversary, Hawking theorised on the existence of extraterrestrial life, believing that "primitive life is very common and intelligent life is fairly rare."[22]
Losing an old bet
Main article: Thorne–Hawking–Preskill bet
U.S. President Barack Obama talks with Stephen Hawking in the Blue Room of the White House before a ceremony presenting him and fifteen others the Presidential Medal of Freedom on 12 August 2009. The Medal of Freedom is the nation's highest civilian honour.

Hawking was in the news in July 2004 for presenting a new theory about black holes which goes against his own long-held belief about their behaviour, thus losing a bet he made with Kip Thorne and John Preskill of Caltech. Classically, it can be shown that information crossing the event horizon of a black hole is lost to our universe, and that thus all black holes are identical beyond their mass, electrical charge and angular velocity (the "no hair theorem"). The problem with this theorem is that it implies the black hole will emit the same radiation regardless of what goes into it, and as a consequence that if a pure quantum state is thrown into a black hole, an "ordinary" mixed state will be returned. This runs counter to the rules of quantum mechanics and is known as the black hole information paradox.
