Stephen Hawking is regarded as one of the most brilliant theoretical physicists in history. 

His work on the origins and structure of the universe, from the Big Bang to black holes, revolutionized the field, while his best-selling books have appealed to readers who may not have Hawking's scientific background. Hawking died on March 14, 2018 , at the age of 76.

Stephen Hawking was seen by many as the world's smartest person, though he never revealed his IQ score. When asked about his IQ score by a New York Times reporter he replied, "I have no idea, people who boast about their IQ are losers," according to the news site The Atlantic .

In this brief biography, we look at Hawking's education and career — ranging from his discoveries to the popular books he's written — and the disease that robbed him of mobility and speech.   

The early life of Stephen Hawking

British cosmologist Stephen William Hawking was born in Oxford, England on Jan. 8, 1942  — 300 years to the day after the death of the astronomer Galileo Galilei . He attended University College, Oxford, where he studied physics, despite his father's urging to focus on medicine. Hawking went on to Cambridge to research cosmology , the study of the universe as a whole. 

In early 1963, just shy of his 21st birthday, Hawking was diagnosed with motor neuron disease, more commonly known as Lou Gehrig's disease or amyotrophic lateral sclerosis (ALS) . Doctors told Hawkings that he would likely not survive more than two years with the disease. Completing his doctorate did not appear likely, but Hawking defied the odds. He also obtained his PhD in 1966 for his thesis entitled " Properties of expanding universes ". In that same year, Hawking also won the prestigious Adams Prize for his essay entitled "Singularities and the Geometry of Space-Time".

From then Hawking went on to forge new roads into the understanding of the universe in the decades since. 

As the disease spread, Hawking became less mobile and began using a wheelchair. Talking grew more challenging and, in 1985, an emergency tracheotomy caused his total loss of speech. A speech-generating device constructed at Cambridge, combined with a software program, served as his electronic voice, allowing Hawking to select his words by moving the muscles in his cheek.

Just before his diagnosis, Hawking met Jane Wilde, and the two were married in 1965. The couple had three children before separating in 1990. Hawking remarried in 1995 to Elaine Mason but divorced in 2006.

Stephen Hawking's greatest scientific achievements

Throughout his career, Hawking proposed several theories regarding astronomical anomalies, posed curious questions about the cosmos and enlightened the world about the origin of everything. Here are just some of the many milestones Hawking made in the name of science. 

In 1970, Hawkings and fellow physicist and Oxford classmate, Roger Penrose, published a joint paper entitled " The singularities of gravitational collapse and cosmology ". In this paper, Hawking and Penrose proposed a new theory of spacetime singularities — a breakdown in the fabric of the universe found in one of Hawking's later discoveries, the black hole. This early work not only challenged concepts in physics but also supported the concept of the Big Bang as the birth of the universe, as outlined in Albert Einstein's theory of general relativity in the 1940s. 

Over the course of his career, Hawking studied the basic laws governing the universe. In 1974, Hawking published another paper called " Black hole explosions? ", in which he outlined a theorem that united Einstein's theory of general relativity, with quantum theory — which explains the behavior of matter and energy on an atomic level. In this new paper, Hawking hypothesized that matter not only fell into the gravitational pull of black holes but that photons radiated from them — which has now been confirmed in laboratory experiments by the Technion-Israel Institute of Technology in Israel — aptly named "Hawking radiation". 

In 1974, Hawking was inducted into the Royal Society, a worldwide fellowship of scientists. Five years later, he was appointed Lucasian Professor of Mathematics at Cambridge, the most famous academic chair in the world (the second holder was Sir Isaac Newton , also a member of the Royal Society).

During the 1980s, Hawking turned his attention to the Big Bang and the uncertainties about the beginning of the universe. "Events before the Big Bang are simply not defined, because there’s no way one could measure what happened at them. Since events before the Big Bang have no observational consequences, one may as well cut them out of the theory and say that time began at the Big Bang," he said during his lecture called The Beginning of Time . In 1983, Hawking, along with scientists James Harlte, published a paper outlining their " no-boundary proposal " for the universe. In their paper, Hawking and Hartle describe the shape of the universe as reminiscent of a shuttlecock — with the Big Bang at the narrowest point and the expanding universe emerging from it.

Books by Stephen Hawking

In the last three decades of Hawking's life, he not only continued to publish academic literature, but he also published several popular science books to share his theories of the history of the universe with the layperson. His most popular book " A Brief History of Time " (10th-anniversary edition: Bantam, 1998) was first published in 1988 and became an international bestseller. It has sold almost 10 million copies and has been translated into 40 different languages.

Hawking went on to write other nonfiction books aimed at non-scientists. These include " A Briefer History of Time ," " The Universe in a Nutshell ," " The Grand Design " and " On the Shoulders of Giants ." 

Along with his many successful books about the inner workings of the universe, Hawking also began a series of science fiction books called " George and the Big Bang ", with his daughter Lucy Hawking in 2011. Aimed at middle school children, the series follows George's adventures as he travels through space. 

Stephen Hawking's filmography

Hawking has made several television appearances, including a playing hologram of himself on "Star Trek: The Next Generation" and a cameo on the television show "Big Bang Theory." He has also voiced himself in several episodes of the animated series "Futurama" and "The Simpson". In 1997, PBS also presented an educational miniseries titled " Stephen Hawking's Universe ," which probes the theories of the cosmologist. 

 In 2014, a movie based on Hawking's life was released. Called "The Theory of Everything," the film drew praise from Hawking , who said it made him reflect on his own life. "Although I'm severely disabled, I have been successful in my scientific work," Hawking wrote on Facebook in November 2014. "I travel widely and have been to Antarctica and Easter Island, down in a submarine and up on a zero-gravity flight. One day, I hope to go into space."

Stephen Hawking's quotes and controversial statements

Hawking's quotes range from notable to poetic to controversial. Among them: 

• "Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe? The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing? "— A Brief History of Time: From the Big Bang to Black Holes , 1988 
• "All of my life, I have been fascinated by the big questions that face us, and have tried to find scientific answers to them. If, like me, you have looked at the stars, and tried to make sense of what you see, you too have started to wonder what makes the universe exist."— Stephen Hawking's Universe , 1997.  
• "Science predicts that many different kinds of universe will be spontaneously created out of nothing. It is a matter of chance which we are in." — The Guardian, 2011 .
• "We should seek the greatest value of our action." — The Guardian, 2011. 
• "The whole history of science has been the gradual realization that events do not happen in an arbitrary manner, but that they reflect a certain underlying order, which may or may not be divinely inspired. "— A Brief History of Time: From the Big Bang to Black Holes , 1988.   
• "The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge."  
• "It is not clear that intelligence has any long-term survival value." — Life in the Universe , 1996.  
• "One cannot really argue with a mathematical theorem." — A Brief History of Time: From the Big Bang to Black Holes , 1988.  
• "It is a waste of time to be angry about my disability. One has to get on with life and I haven't done badly. People won't have time for you if you are always angry or complaining." — The Guardian, 2005 . 
• "I relish the rare opportunity I've been given to live the life of the mind. But I know I need my body and that it will not last forever." — Stem Cell Universe , 2014. 

A list of Hawking quotes would be incomplete without mentioning some of his more controversial statements.

He frequently said that humans must leave Earth if we wished to survive. 

• "It will be difficult enough to avoid disaster in the next hundred years, let alone the next thousand or million...Our only chance of long-term survival is not to remain inward-looking on planet Earth, but to spread out into space," he said during an interview with video site Big Think , 2010. 
• "[W]e must … continue to go into space for the future of humanity…I don't think we will survive another 1,000 years without escaping beyond our fragile planet,"  Hawking said during a lecture at the Oxford Union debating society , 2016. 
• "We are running out of space and the only places to go to are other worlds. It is time to explore other solar systems. Spreading out may be the only thing that saves us from ourselves. I am convinced that humans need to leave Earth," he said during a speech at the Starmus Festival in Norway, 2017. 

He also said time travel should be possible, and that we should explore space for the romance of it. 

"Time travel used to be thought of as just science fiction, but Einstein's general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out. I was one of the first to write about the conditions under which this would be possible. I showed it would require matter with negative energy density, which may not be available. Other scientists took courage from my paper and wrote further papers on the subject," he told the new site Parade in 2010. "Science is not only a disciple of reason, but, also, one of romance and passion," he adds.

The theoretical physicist was also concerned that robots could not only have an impact on the economy but also mean doom for humanity.

"The automation of factories has already decimated jobs in traditional manufacturing, and the rise of artificial intelligence is likely to extend this job destruction deep into the middle classes, with only the most caring, creative or supervisory roles remaining," he wrote in a 2016 column in The Guardian .

"The development of full artificial intelligence could spell the end of the human race," he told the BBC in 2014. Hawking added, however, that AI developed to date has been helpful. It's more the self-replication potential that worries him. "It would take off on its own, and re-design itself at an ever-increasing rate. Humans, who are limited by slow biological evolution, couldn't compete, and would be superseded."

"The genie is out of the bottle. I fear that AI may replace humans altogether," Hawking told WIRED in November 2017.

An avowed atheist, Hawking also occasionally waded into the topic of religion.

• "Because there is a law such as gravity, the universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the universe going." — The Grand Design, by Stephen Hawking and Leonard Mlodinow. 
• "I regard the brain as a computer which will stop working when its components fail…There is no heaven or afterlife for broken down computers; that is a fairy story for people afraid of the dark," he said during a 2011 interview with The Guardian .
• "Before we understand science, it is natural to believe that God created the universe. But now science offers a more convincing explanation. What I meant by 'we would know the mind of God' is, we would know everything that God would know, if there were a God, which there isn't. I'm an atheist," Hawking said in a 2014 interview with the news site El Mundo .

Stephen Hawking

Stephen Hawking was a scientist known for his work with black holes and relativity, and the author of popular science books like 'A Brief History of Time.'

(1942-2018)

Who Was Stephen Hawking?

Stephen Hawking was a British scientist, professor and author who performed groundbreaking work in physics and cosmology, and whose books helped to make science accessible to everyone.

Hawking was born on January 8, 1942, in Oxford, England. His birthday was also the 300th anniversary of the death of Galileo — long a source of pride for the noted physicist.

The eldest of Frank and Isobel Hawking's four children, Hawking was born into a family of thinkers.

His Scottish mother earned her way into Oxford University in the 1930s — a time when few women were able to go to college. His father, another Oxford graduate, was a respected medical researcher with a specialty in tropical diseases.

Hawking's birth came at an inopportune time for his parents, who didn't have much money. The political climate was also tense, as England was dealing with World War II and the onslaught of German bombs in London, where the couple was living as Frank Hawking undertook research in medicine.

In an effort to seek a safer place, Isobel returned to Oxford to have the couple's first child. The Hawkings would go on to have two other children, Mary and Philippa. And their second son, Edward, was adopted in 1956.

The Hawkings, as one close family friend described them, were an "eccentric" bunch. Dinner was often eaten in silence, each of the Hawkings intently reading a book. The family car was an old London taxi, and their home in St. Albans was a three-story fixer-upper that never quite got fixed. The Hawkings also housed bees in the basement and produced fireworks in the greenhouse.

In 1950, Hawking's father took work to manage the Division of Parasitology at the National Institute of Medical Research, and spent the winter months in Africa doing research. He wanted his eldest child to go into medicine, but at an early age, Hawking showed a passion for science and the sky.

That was evident to his mother, who, along with her children, often stretched out in the backyard on summer evenings to stare up at the stars. "Stephen always had a strong sense of wonder," she remembered. "And I could see that the stars would draw him."

Hawking was also frequently on the go. With his sister Mary, Hawking, who loved to climb, devised different entry routes into the family home. He loved to dance and also took an interest in rowing, becoming a team coxswain in college.

Early in his academic life, Hawking, while recognized as bright, was not an exceptional student. During his first year at St. Albans School , he was third from the bottom of his class.

But Hawking focused on pursuits outside of school; he loved board games, and he and a few close friends created new games of their own. During his teens, Hawking, along with several friends, constructed a computer out of recycled parts for solving rudimentary mathematical equations.

Hawking entered University College at the University of Oxford at the age of 17. Although he expressed a desire to study mathematics, Oxford didn't offer a degree in that specialty, so Hawking gravitated toward physics and, more specifically, cosmology.

By his own account, Hawking didn't put much time into his studies. He would later calculate that he averaged about an hour a day focusing on school. And yet he didn't really have to do much more than that. In 1962, he graduated with honors in natural science and went on to attend Trinity Hall at the University of Cambridge for a Ph.D. in cosmology.

In 1968, Hawking became a member of the Institute of Astronomy in Cambridge. The next few years were a fruitful time for Hawking and his research. In 1973, he published his first, highly-technical book, The Large Scale Structure of Space-Time , with G.F.R. Ellis.

In 1979, Hawking found himself back at the University of Cambridge, where he was named to one of teaching's most renowned posts, dating back to 1663: the Lucasian Professor of Mathematics.

Wife and Children

At a New Year's party in 1963, Hawking met a young languages undergraduate named Jane Wilde. They were married in 1965. The couple gave birth to a son, Robert, in 1967, and a daughter, Lucy, in 1970. A third child, Timothy, arrived in 1979.

In 1990, Hawking left his wife Jane for one of his nurses, Elaine Mason. The two were married in 1995. The marriage put a strain on Hawking's relationship with his own children, who claimed Elaine closed off their father from them.

In 2003, nurses looking after Hawking reported their suspicions to police that Elaine was physically abusing her husband. Hawking denied the allegations, and the police investigation was called off. In 2006, Hawking and Elaine filed for divorce.

In the following years, the physicist reportedly grew closer to his family. He reconciled with Jane, who had remarried. And he published five science-themed novels for children with his daughter, Lucy.

Stephen Hawking: Books

Over the years, Hawking wrote or co-wrote a total of 15 books. A few of the most noteworthy include:

'A Brief History of Time'

In 1988 Hawking catapulted to international prominence with the publication of A Brief History of Time . The short, informative book became an account of cosmology for the masses and offered an overview of space and time, the existence of God and the future.

The work was an instant success, spending more than four years atop the London Sunday Times' best-seller list. Since its publication, it has sold millions of copies worldwide and been translated into more than 40 languages.

‘The Universe in a Nutshell’

A Brief History of Time also wasn't as easy to understand as some had hoped. So in 2001, Hawking followed up his book with The Universe in a Nutshell , which offered a more illustrated guide to cosmology's big theories.

‘A Briefer History of Time’

In 2005, Hawking authored the even more accessible A Briefer History of Time , which further simplified the original work's core concepts and touched upon the newest developments in the field like string theory.

Together these three books, along with Hawking's own research and papers, articulated the physicist's personal search for science's Holy Grail: a single unifying theory that can combine cosmology (the study of the big) with quantum mechanics (the study of the small) to explain how the universe began.

This kind of ambitious thinking allowed Hawking, who claimed he could think in 11 dimensions, to lay out some big possibilities for humankind. He was convinced that time travel is possible, and that humans may indeed colonize other planets in the future.

‘The Grand Design’

In September 2010, Hawking spoke against the idea that God could have created the universe in his book The Grand Design . Hawking previously argued that belief in a creator could be compatible with modern scientific theories.

In this work, however, he concluded that the Big Bang was the inevitable consequence of the laws of physics and nothing more. "Because there is a law such as gravity, the universe can and will create itself from nothing," Hawking said. "Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist."

The Grand Design was Hawking's first major publication in almost a decade. Within his new work, Hawking set out to challenge Isaac Newton 's belief that the universe had to have been designed by God, simply because it could not have been born from chaos. "It is not necessary to invoke God to light the blue touch paper and set the universe going," Hawking said.

At the age of 21, Hawking was diagnosed with amyotrophic lateral sclerosis (ALS, or Lou Gehrig 's disease). In a very simple sense, the nerves that controlled his muscles were shutting down. At the time, doctors gave him two and a half years to live.

Hawking first began to notice problems with his physical health while he was at Oxford — on occasion he would trip and fall, or slur his speech — but he didn't look into the problem until 1963, during his first year at Cambridge. For the most part, Hawking had kept these symptoms to himself.

But when his father took notice of the condition, he took Hawking to see a doctor. For the next two weeks, the 21-year-old college student made his home at a medical clinic, where he underwent a series of tests.

"They took a muscle sample from my arm, stuck electrodes into me, and injected some radio-opaque fluid into my spine, and watched it going up and down with X-rays, as they tilted the bed," he once said. "After all that, they didn't tell me what I had, except that it was not multiple sclerosis, and that I was an atypical case."

Eventually, however, doctors did diagnose Hawking with the early stages of ALS. It was devastating news for him and his family, but a few events prevented him from becoming completely despondent.

The first of these came while Hawking was still in the hospital. There, he shared a room with a boy suffering from leukemia. Relative to what his roommate was going through, Hawking later reflected, his situation seemed more tolerable.

Not long after he was released from the hospital, Hawking had a dream that he was going to be executed. He said this dream made him realize that there were still things to do with his life.

In a sense, Hawking's disease helped turn him into the noted scientist he became. Before the diagnosis, Hawking hadn't always focused on his studies. "Before my condition was diagnosed, I had been very bored with life," he said. "There had not seemed to be anything worth doing."

With the sudden realization that he might not even live long enough to earn his Ph.D., Hawking poured himself into his work and research.

As physical control over his body diminished (he'd be forced to use a wheelchair by 1969), the effects of his disease started to slow down. Over time, however, Hawking's ever-expanding career was accompanied by an ever-worsening physical state.

How Did Stephen Hawking Talk?

By the mid-1970s, the Hawking family had taken in one of Hawking's graduate students to help manage his care and work. He could still feed himself and get out of bed, but virtually everything else required assistance.

In addition, his speech had become increasingly slurred, so that only those who knew him well could understand him. In 1985 he lost his voice for good following a tracheotomy. The resulting situation required 24-hour nursing care for the acclaimed physicist.

It also put in peril Hawking's ability to do his work. The predicament caught the attention of a California computer programmer, who had developed a speaking program that could be directed by head or eye movement. The invention allowed Hawking to select words on a computer screen that were then passed through a speech synthesizer.

At the time of its introduction, Hawking, who still had use of his fingers, selected his words with a handheld clicker. Eventually, with virtually all control of his body gone, Hawking directed the program through a cheek muscle attached to a sensor.

Through the program, and the help of assistants, Hawking continued to write at a prolific rate. His work included numerous scientific papers, of course, but also information for the non-scientific community.

Hawking's health remained a constant concern—a worry that was heightened in 2009 when he failed to appear at a conference in Arizona because of a chest infection. In April, Hawking, who had already announced he was retiring after 30 years from the post of Lucasian Professor of Mathematics at Cambridge, was rushed to the hospital for being what university officials described as "gravely ill," though he later made a full recovery.

Research on the Universe and Black Holes

In 1974, Hawking's research turned him into a celebrity within the scientific world when he showed that black holes aren't the information vacuums that scientists had thought they were.

In simple terms, Hawking demonstrated that matter, in the form of radiation, can escape the gravitational force of a collapsed star. Another young cosmologist, Roger Penrose, had earlier discovered groundbreaking findings about the fate of stars and the creation of black holes, which tapped into Hawking's own fascination with how the universe began.

The pair then began working together to expand upon Penrose’s earlier work, setting Hawking on a career course marked by awards, notoriety and distinguished titles that reshaped the way the world thinks about black holes and the universe.

When Hawking’s radiation theory was born, the announcement sent shock waves of excitement through the scientific world. Hawking was named a fellow of the Royal Society at the age of 32, and later earned the prestigious Albert Einstein Award, among other honors. He also earned teaching stints at Caltech in Pasadena, California, where he served as visiting professor, and at Gonville and Caius College in Cambridge.

In August 2015, Hawking appeared at a conference in Sweden to discuss new theories about black holes and the vexing "information paradox." Addressing the issue of what becomes of an object that enters a black hole, Hawking proposed that information about the physical state of the object is stored in 2D form within an outer boundary known as the "event horizon." Noting that black holes "are not the eternal prisons they were once thought," he left open the possibility that the information could be released into another universe.

Beginning of the Universe

In a March 2018 interview on Neil deGrasse Tyson 's Star Talk , Hawking addressed the topic of "what was around before the Big Bang" by stating there was nothing around. He said by applying a Euclidean approach to quantum gravity, which replaces real time with imaginary time, the history of the universe becomes like a four-dimensional curved surface, with no boundary.

He suggested picturing this reality by thinking of imaginary time and real time as beginning at the Earth's South Pole, a point of space-time where the normal laws of physics hold; as there is nothing "south" of the South Pole, there was also nothing before the Big Bang.

Hawking and Space Travel

In 2007, at the age of 65, Hawking made an important step toward space travel. While visiting the Kennedy Space Center in Florida, he was given the opportunity to experience an environment without gravity.

Over the course of two hours over the Atlantic, Hawking, a passenger on a modified Boeing 727, was freed from his wheelchair to experience bursts of weightlessness. Pictures of the freely floating physicist splashed across newspapers around the globe.

"The zero-G part was wonderful, and the high-G part was no problem. I could have gone on and on. Space, here I come!" he said.

Hawking was scheduled to fly to the edge of space as one of Sir Richard Branson 's pioneer space tourists. He said in a 2007 statement, "Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global warming , nuclear war, a genetically engineered virus or other dangers. I think the human race has no future if it doesn't go into space. I therefore want to encourage public interest in space."

Stephen Hawking Movie and TV Appearances

If there is such a thing as a rock-star scientist, Hawking embodied it. His forays into popular culture included guest appearances on The Simpsons , Star Trek: The Next Generation , a comedy spoof with comedian Jim Carrey on Late Night with Conan O'Brien , and even a recorded voice-over on the Pink Floyd song "Keep Talking."

In 1992, Oscar-winning filmmaker Errol Morris released a documentary about Hawking's life, aptly titled A Brief History of Time . Other TV and movie appearances included:

'The Big Bang Theory'

In 2012, Hawking showed off his humorous side on American television, making a guest appearance on The Big Bang Theory . Playing himself on this popular comedy about a group of young, geeky scientists, Hawking brings the theoretical physicist Sheldon Cooper ( Jim Parsons ) back to Earth after finding an error in his work. Hawking earned kudos for this light-hearted effort.

'The Theory of Everything'

In November of 2014, a film about the life of Hawking and Jane Wilde was released. The Theory of Everything stars Eddie Redmayne as Hawking and encompasses his early life and school days, his courtship and marriage to Wilde, the progression of his crippling disease and his scientific triumphs.

In May 2016, Hawking hosted and narrated Genius , a six-part television series which enlists volunteers to tackle scientific questions that have been asked throughout history. In a statement regarding his series, Hawking said Genius is “a project that furthers my lifelong aim to bring science to the public. It’s a fun show that tries to find out if ordinary people are smart enough to think like the greatest minds who ever lived. Being an optimist, I think they will.”

In 2011, Hawkings had participated in a trial of a new headband-styled device called the iBrain. The device is designed to "read" the wearer's thoughts by picking up "waves of electrical brain signals," which are then interpreted by a special algorithm, according to an article in The New York Times . This device could be a revolutionary aid to people with ALS.

Hawking on AI

In 2014, Hawking, among other top scientists, spoke out about the possible dangers of artificial intelligence, or AI, calling for more research to be done on all of possible ramifications of AI. Their comments were inspired by the Johnny Depp film Transcendence , which features a clash between humanity and technology.

"Success in creating AI would be the biggest event in human history," the scientists wrote. "Unfortunately, it might also be the last, unless we learn how to avoid the risks." The group warned of a time when this technology would be "outsmarting financial markets, out-inventing human researchers, out-manipulating human leaders, and developing weapons we cannot even understand."

Hawking reiterated this stance while speaking at a technology conference in Lisbon, Portugal, in November 2017. Noting how AI could potentially make gains in wiping out poverty and disease, but could also lead to such theoretically destructive actions as the development of autonomous weapons, he said, "We cannot know if we will be infinitely helped by AI, or ignored by it and sidelined, or conceivably destroyed by it."

Hawking and Aliens

In July 2015, Hawking held a news conference in London to announce the launch of a project called Breakthrough Listen. Funded by Russian entrepreneur Yuri Milner, Breakthrough Listen was created to devote more resources to the discovery of extraterrestrial life.

Breaking the Internet

In October 2017, Cambridge University posted Hawking's 1965 doctoral thesis, "Properties of Expanding Universes," to its website. An overwhelming demand for access promptly crashed the university server, though the document still fielded a staggering 60,000 views before the end of its first day online.

When Did Stephen Hawking Die?

On March 14, 2018, Hawking finally died of ALS, the disease that was supposed to have killed him more than 50 years earlier. A family spokesman confirmed that the iconic scientist died at his home in Cambridge, England.

The news touched many in his field and beyond. Fellow theoretical physicist and author Lawrence Krauss tweeted: "A star just went out in the cosmos. We have lost an amazing human being. Hawking fought and tamed the cosmos bravely for 76 years and taught us all something important about what it truly means to celebrate about being human."

Hawking's children followed with a statement: "We are deeply saddened that our beloved father passed away today. He was a great scientist and an extraordinary man whose work and legacy will live on for many years. His courage and persistence with his brilliance and humor inspired people across the world. He once said, 'It would not be much of a universe if it wasn’t home to the people you love.' We will miss him forever."

Later in the month, it was announced that Hawking's ashes would be interred at Westminster Abbey in London, alongside other scientific luminaries like Isaac Newton and Charles Darwin .

On May 2, 2018, his final paper, titled "A smooth exit from eternal inflation?" was published in the Journal of High Energy Physics . Submitted 10 days before his death, the new report, co-authored by Belgian physicist Thomas Hertog, disputes the idea that the universe will continue to expand.

• My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.
• Not only does God definitely play dice, but He sometimes confuses us by throwing them where they can't be seen.
• Intelligence is the ability to adapt to change.
• Before my condition was diagnosed, I had been very bored with life. There had not seemed to be anything worth doing.
• I believe that life on Earth is at an ever increasing risk of being wiped out by a disaster such as sudden global warming, nuclear war, a genetically engineered virus, or other dangers. I think the human race has no future if it doesn't go into space.
• Because there is a law such as gravity, the universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist.
• It is not necessary to invoke God to light the blue touch paper and set the universe going.
• It is not clear that intelligence has any long-term survival value.
• If, like me, you have looked at the stars, and tried to make sense of what you see, you too have started to wonder what makes the universe exist.
• I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken down computers; that is a fairy story for people afraid of the dark.

Stephen Hawking was born on January 8, 1942, in Oxfordshire, England, where his mother had been sent for safety during the German bombings of London of World War II. His mother Isobel Hawking was an Oxford graduate and his father Frank Hawking was a medical researcher.

After Stephen's birth, the family reunited in London, where his father headed the division of parasitology at the National Institute for Medical Research. The family then moved to St. Albans so that Stephen's father could pursue medical research at the nearby Institute for Medical Research in Mill Hill.

Education and Medical Diagnosis

Stephen Hawking attended school in St. Albans, where he was an unexceptional student. His brilliance was much more apparent in his years at Oxford University. He specialized in physics and graduated with first-class honors despite his relative lack of diligence. In 1962, he continued his education at Cambridge University, pursuing a Ph.D. in cosmology.

At age 21, a year after beginning his doctoral program, Stephen Hawking was diagnosed with amyotrophic lateral sclerosis (also known as motor neuron disease, ALS, and Lou Gehrig's disease). Given only three years to live, he has written that this prognosis helped motivate him in his physics work .

There is little doubt that his ability to remain actively engaged with the world through his scientific work helped him persevere in the face of the disease. The support of family and friends were equally key. This is vividly portrayed in the dramatic film "The Theory of Everything."

The ALS Progresses

As his illness progressed, Hawking became less mobile and began using a wheelchair. As part of his condition, Hawking eventually lost his ability to speak, so he utilized a device capable of translating his eye movements (since he could no longer utilize a keypad) to speak in a digitized voice.

In addition to his keen mind within physics, he gained respect throughout the world as a science communicator. His achievements are deeply impressive on their own, but some of the reason he is so universally respected was his ability to accomplish so much while suffering the severe debility caused by ALS.

Marriage and Children

Just before his diagnosis, Hawking met Jane Wilde, and the two were married in 1965. The couple had three children before separating. Hawking later married Elaine Mason in 1995 and they divorced in 2006.

Career as Academic and Author

Hawking stayed on at Cambridge after his graduation, first as a research fellow and then as a professional fellow. For most of his academic career, Hawking served as the Lucasian Professor of Mathematics at the University of Cambridge, a position once held by Sir Isaac Newton .

Following a long tradition, Hawking retired from this post at age 67, in the spring of 2009, though he continued his research at the university's cosmology institute. In 2008 he also accepted a position as a visiting researcher at Waterloo, Ontario's Perimeter Institute for Theoretical Physics.

In 1982 Hawking began work on a popular book on cosmology. By 1984 he had produced the first draft of "A Brief History of Time," which he published in 1988 after some medical setbacks. This book remained on the Sunday Times bestsellers list for 237 weeks. Hawking's even more accessible "A Briefer History of Time" was published in 2005.

Fields of Study

Hawking's major research was in the areas of theoretical cosmology , focusing on the evolution of the universe as governed by the laws of general relativity . He is most well-known for his work in the study of black holes . Through his work, Hawking was able to:

• Prove that singularities are general features of spacetime.
• Provide mathematical proof that information which fell into a black hole was lost.
• Demonstrate that black holes evaporate through Hawking radiation .

On March 14, 2018, Stephen Hawking died in his home in Cambridge, England. He was 76. His ashes were placed in London’s Westminster Abbey between the final resting places of Sir Isaac Newton and Charles Darwin.

Stephen Hawking made large contributions as a scientist, science communicator, and as a heroic example of how enormous obstacles can be overcome. The Stephen Hawking Medal for Science Communication is a prestigious award that "recognizes the merit of popular science on an international level."

Thanks to his distinctive appearance, voice, and popularity, Stephen Hawking is often represented in popular culture. He made appearances on the television shows "The Simpsons" and "Futurama," as well as having a cameo on "Star Trek: The Next Generation" in 1993.

"The Theory of Everything," a biographical drama film about Hawking's life, was released in 2014.

Stephen Hawking

A life in science: second edition (2002).

Originally published in 1992 to great acclaim, this updated edition traces the course of Hawking’s life and science, successfully marrying biography and physics to tell the story of a remarkable man.

Stephen Hawking is no ordinary scientist. With a career that began over thirty years ago at Cambridge University, he has managed to do more than perhaps any other scientist to broaden our basic understanding of the universe. His theoretical work on black holes and his progress in advancing our knowledge of the origin and nature of the cosmos have been groundbreaking—if not downright revolutionary.

Stephen Hawking has also spent much of his adult life confined to a wheelchair, a victim of ALS, a degenerative motor neuron disease. Clearly his physical limitations have done nothing to confine him intellectually. He simply never allowed his illness to hinder his scientific development. In fact, many would argue that his liberation from the routine chores of life has allowed him to focus his efforts more keenly on his science.

Hawking certainly would have been remarkable for his cutting edge work in theoretical physics alone. However, he has also managed to popularize science in a way unparalleled by other scientists of his stature. He became a household name, achieving almost cult-like fame, with the release of his best-selling book, A Brief History of Time. Although steeped in the potentially overwhelming complexities of cosmology, he succeeded in selling millions of copies to audiences eager to learn even some of what he has to offer.

Science writers White and Gribbin have skillfully painted a portrait of an indefatigable genius and a scientific mind that seemingly knows no bounds. Knitting together clear explanations of Hawking’s science with a detailed personal history that is both balanced as well as sensitive, we come to know—and appreciate—both.

As Stephen Hawking’s new book, The Universe in a Nutshell, hits the best-seller lists, it is the ideal time for readers to learn more about this remarkable man and his vast body of accomplishments.

Stephen william hawking.

I got an education there that was as good as, if not better than, that I would have had at Westminster. I have never found that my lack of social graces has been a hindrance.

The prevailing attitude at Oxford at that time was very anti-work. You were supposed to be brilliant without effort, or accept your limitations and get a fourth-class degree. To work hard to get a better class of degree was regarded as the mark of a grey man - the worst epithet in the Oxford vocabulary.

... although there was a cloud hanging over my future, I found to my surprise that I was enjoying life in the present more than I had before. I began to make progress with my research...

... I therefore started working for the first time in my life. To my surprise I found I liked it.

... that both time and space are finite in extent, but they don't have any boundary or edge. ... there would be no singularities, and the laws of science would hold everywhere, including at the beginning of the universe.

I was in Geneva, at CERN, the big particle accelerator, in the summer of 1985 . ... I caught pneumonia and was rushed to hospital. The hospital in Geneva suggested to my wife that it was not worth keeping the life support machine on. But she was having none of that. I was flown back to Addenbrooke's Hospital in Cambridge, where a surgeon called Roger Grey carried out a tracheotomy. That operation saved my life but took away my voice.

While many prominent physicists, cosmologists and astronomers have made important contributions to the study of quantum gravity and cosmology, the impact of Stephen Hawking's contributions to the field truly stand out. Although his work on black hole thermodynamics is perhaps the most well known, Hawking has also made major contributions to the study of singularity theorems in general relativity, black hole uniqueness, quantum fields in curved spacetimes, Euclidean quantum gravity, the wave function of the universe and many other areas as well. In addition to his own work, Hawking has served as advisor and mentor to a remarkable set of students. Furthermore, it would be hard to imagine assembling any list of researchers working in quantum cosmology without including a large number of Hawking's students and close colleagues. Thus the group that gathered at the CMS in Cambridge in honour of his 60 th birthday includes some of the leading theorists in the field.

... for boldness and creativity in gravitational physics, best illustrated by the prediction that black holes should emit black body radiation and evaporate, and for the special gift of making abstract ideas accessible and exciting to experts, generalists, and the public alike.

Stephen Hawking has contributed as much as anyone since Einstein to our understanding of gravity. This medal is a fitting recognition of an astonishing research career spanning more than 40 years.

Stephen Hawking is a definitive hero to all of us involved in exploring the Cosmos. His contribution to science is unique and he serves as a continuous inspiration to every thinking person. It was an honour for the crew of the STS- 121 mission to fly his medal into space. We think that this is particularly appropriate as Stephen has dedicated his life to thinking about the larger Universe.

This is a very distinguished medal. It was awarded to Darwin, Einstein and Crick. I am honoured to be in their company.

HAWKING HAWKING The Selling of a Scientific Celebrity By Charles Seife

Stephen Hawking was, by a wide margin, the best-known figure from the world of science from the mid-1980s until his death in 2018. “Hawking Hawking,” by the accomplished science journalist and historian Charles Seife, is a tough-minded portrait of the theoretical physicist. Taken literally, though, the book’s provocative title is misleading: “Hawking Hawking” is a full-fledged biography, not an exposé or takedown. But the title accurately captures the book’s iconoclastic spirit. This is not another contribution to the vast Hawking hagiography.

Let me briefly recall the most basic facts of Hawking’s life. In 1942 he was born in Oxford, England, into an accomplished medical and academic family. He received his undergraduate degree from Oxford and got his Ph.D. from Cambridge in 1966, largely based on his mathematical proof that showed that an expanding universe must begin in a singularity — the singularity theorem.

As early as 1963 he began to develop symptoms of motor neurone disease, also known as A.L.S. This disease typically runs a fatal course within a few years, but Hawking’s illness developed slowly. Still, his condition worsened over time. By the late 1970s his speech was difficult to understand and he was in a wheelchair. Despite his physical challenges Hawking continued to produce good work in physics, including most notably his startling theoretical demonstration, in 1974, that black holes should spontaneously radiate — a phenomenon that came to be known as Hawking radiation. Although observation has been elusive owing to the smallness of the effect, Hawking radiation is one of the most outstanding applications of quantum mechanics to gravitation, and it continues to inspire hundreds of research papers yearly.

In 1979 Hawking was appointed to the Lucasian professorship at Cambridge, a position previously occupied by Isaac Newton, Charles Babbage and Paul Dirac. “A Brief History of Time,” Hawking’s presentation of his work for a popular audience, appeared in 1988 and it made the best-seller lists for several years. Stephen Hawking became an iconic celebrity, instantly recognizable to millions if not billions of people all over the world.

Though it is not an authorized biography, “Hawking Hawking” is deeply researched and richly sourced. It incorporates fresh interviews with many people who interacted closely with Hawking, including students, collaborators and intellectual rivals.

This is a book meant for general readers. It describes the cultural and the broad scientific context of Hawking’s work, and its reception, but it does not provide self-contained accounts of the work itself. If you want to learn what singularity theorems, Hawking radiation or the no-boundary proposal is all about, you will have to look elsewhere. Seife succeeds in serving up something of the flavor of those difficult and rather esoteric ideas, which are the heart of Hawking’s contribution to science, in a way that won’t give general readers indigestion. But it may leave you hungry for more. If so, so much the better, because even Wikipedia and Google will reward your motivated searches.

It’s worth noting Seife’s odd choice to narrate his story using reverse chronology. He begins thus with Hawking’s death and ends with his childhood. It’s an unusual but stimulating structure. Indeed, the phenomenon of a nearly “locked-in,” physically helpless and noncommunicative figure, having inspired the adulation of millions for his intellectual mastery over the universe, being interred next to Sir Isaac Newton in Westminster Abbey, is so extraordinary that unraveling step by step the question of “How did this happen?” might keep you turning the pages. But the time-reversed narrative is not well matched to how readers usually understand stories, nor to the logical evolution of ideas. I had to jump around quite a bit, and I imagine that people less familiar with the science could easily lose the thread.

In the popular imagination Hawking was a transcendent scientist and a pure spirit who courageously overcame profound physical disabilities while he also happened to become a publishing sensation and a performance icon, more or less as a trivial consequence. That image is recognizably based on a uniquely inspiring life of achievement, but, as Seife amply documents, it paints an idealized picture. Hawking did important work in two splendid but rather speculative, unworldly branches of theoretical physics, namely the mathematical theories (as opposed to the phenomenology) of black holes and of Big Bang cosmology. He most certainly did not pioneer a “Theory of Everything,” as was often reported, nor did practicing physicists hang onto his every pronouncement. He did his best work well before the worst of his physical deterioration, and his personal life was in parts problematic. “A Brief History of Time,” his runaway hit, is not a masterpiece of science or of exposition; and its production and promotion was a calculated team effort.

I got to know Hawking well during a weeklong conference on cosmology he organized (together with Gary Gibbons) in the summer of 1983. By this time his speech was unintelligible at first exposure, but with a bit of practice one got to understand it, and more-or-less normal conversations were possible. He and his first wife, Jane Wilde, were very gracious hosts to me and my wife, Betsy Devine, when we arrived with a baby and young child in tow. He was a good-humored and witty person. At one point, he enjoyed playing chess with Betsy while baby Mira methodically undid his shoelaces. We became family friends. The conference proved to be a milestone event, where the central ideas of inflationary cosmology came together and axion cosmology was born. Hawking participated actively in the scientific program, often making sharp observation and posing tough questions, besides putting forward his own version of inflation. In retrospect this conference, sponsored by the Nuffield Foundation, may have marked Hawking’s high point as a practicing scientist. There he guided a new generation of physicists and cosmologists in directions that built on his earlier and ongoing work.

In 1985 Hawking suffered a serious case of pneumonia, which almost killed him. He had to undergo a tracheotomy, after which speech was impossible. He eventually found a computerized speech device that could translate his limited motions into an artificial but very impressive voice. The system was cumbersome and slow, but the theatrical effect it produced, especially in rehearsed presentations on an open stage, was mesmerizing. This was the version of Hawking that most of his public got to know.

The effects of Hawking’s celebrity were complicated, too.

On the positive side: It focused attention on his courage and perseverance in the face of terrible adversity, which can serve as an inspiration to everyone, and especially to people with physical disabilities. It also lent glamour and the spotlight to science, which is poorly represented in popular culture. (That the television sitcom “The Big Bang Theory” might be the most prominent recent depiction of science highlights the problem.) And for Stephen, in what could have been very bleak circumstances, it offered gratification and new experiences.

But: The elevation of tenuous “Theories of Everything” — validated through celebrity rather than by empirical facts — over the vast, open-ended enterprise of engaging the physical world scientifically was, and is, deeply corrosive. His status as an idol was also, I think, hard on Stephen. He knew better. Less would have been more.

Seife has performed an important service by documenting Stephen Hawking’s life as it actually happened. It is what a great scientist deserves, and should expect.

Frank Wilczek is the author of “Fundamentals: Ten Keys to Reality,” and the recipient of the 2004 Nobel Prize in Physics.

Never miss an eclipse, a meteor shower, a rocket launch or any other 2024 event  that’s out of this world with  our space and astronomy calendar .

Scientists may have discovered a major flaw in their understanding of dark energy, a mysterious cosmic force . That could be good news for the fate of the universe.

A new set of computer simulations, which take into account the effects of stars moving past our solar system, has effectively made it harder to predict Earth’s future and reconstruct its past.

Dante Lauretta, the planetary scientist who led the OSIRIS-REx mission to retrieve a handful of space dust , discusses his next final frontier.

A nova named T Coronae Borealis lit up the night about 80 years ago. Astronomers say it’s expected to put on another show  in the coming months.

TIMELINE Stephen Hawking

In Oxford, England

Stephen Hawking is born

He studies thermodinamics,and cuantum physics

hE DECIDES TO Study physics

The doctors say that he will live just for two more years

he discovers that he has got ALS

After some very hard times, he finishes his studies

HE GETS HIS PHD IN PHYSICS

he proves the first of his theories about relativity

Stephen Hawking was born on the 8th January of 1942. When he was about to be born, his parents moved to Oxford, because London was in the middle of the attack of Germany. When he was 17 years old, he wanted to study mathematics, but his father wanted him to study in Oxford, and there wasn't a mathematics career there.

When his doctor told him that he was going to die in just two years, Stephen Hawking suffered a very big depression, and he decided to drop out his studies. He also started going to therapy, and his friends helped him a lot.

Stephen Hawking came out from his depression and he decided that he would spend the time that he had left doing the thing that he loved most, examining the space. Unexpectedly, instead of living just for two more years, he had a long life; even if he lost capabilities little by little, like walking or talking.

He took inspiration on the theory of the relativity which was created by Albert Einstein, and he deepened it. This way, space travelling advanced greatly.

When he was studying in Oxford, he really loved physics, and his teachers knew that he was a very inteligent person, even if he didn't have very good marks.

He is one of the youngest members in history

He becomes a member of the royal society

He discovers that every black hole in the universe is going to colapse.

He makes one of his most important theories

He says that every black hole is a colapsed star

hawking publishes his most important theory

When he couldn't talk, Intel invents this weelchair

Stephen hawking and intel present the famous talking weelchair

He dies the 14th May, in his house in Cambridge

Stephen hawking's death

He became member of the Royal Academy thanks to his contributions on the world of physics. This gave him great world fame, even thoug he was already famous.

30 years later, Stephen Hawking concluded that the black holes are giant stars which imploded and created a nucleus of accumulated mass that attracts everything around it.

When Stephen Hawking couldn't even talk, because of his illness (ALS), Intel told him that they had created a new technology which could make him speak, by using some detectors located in his cheeks. This allowed Hawking to express himself by using the computer in his new weelchair.

He died when he was 76 years old. Stephen Hawking was one of the most inteligent persons in history, and thanks to his theories and his conclusions, space travel has advenced a lot, and there are a lot of thing that we wouldn't have discovered without him

Also in 1974, he made one of his most important finds. In this theory, Stephen Hawking affirmed that there are many more black holes in space than we though. He also said that all the black holes are going to collapse sometime, and this would create a big catastrophe
