Stephen Hawking has died at the age of 76, according to his family. Here is a look back on his life as one of the world's foremost theoretical physicists. British physician Stephen Hawking announces winners of the Stephen Hawking medals during an event held in Guia de Isora's Island, Tenerife, Canary Islands, Spain. For decades, legendary scientist Stephen Hawking was confined to a wheelchair by a form of amyotrophic lateral sclerosis, or Lou Gehrig's Disease, a neurological disease that impacts movement. He communicated via a speech synthesizer.

Stephen Hawking, the theoretical physicist whose work on black holes and cosmology vastly expanded and complicated our understanding of the universe, died at his home in Cambridge, England early Wednesday, the New York Times reports. Hawking was perhaps the most famous living scientist, known as much for his work bringing complicated ideas about the universe to laypeople as for his breakthroughs in physics. His 1988 book A Brief History of Time: From the Big Bang to Black Holes offered a breezy, conversational overview of the current state of the field, covering topics as specific as "The Uncertainty Principle" (chapter four) and as broad as "The Origin and Fate of the Universe" (chapter eight). Hawking gave his own biggest discovery--that black holes can emit radiation--a grand total of fourteen pages, in a chapter entitled "Black Holes Ain't So Black," which seems modest to the point of being glib--but then the 1974 paper in which Hawking announced his findings was titled "Black Hole Explosions?", question mark very much included, so not really out of character. A Brief History of Time became a bestseller, made Hawking a household name, and introduced the search for a grand unified theory into the popular imagination.

Humans must leave Earth in the next 200 years if we want to survive. That was the stark warning issued by Professor Stephen Hawking in the months before his death today at the age of 76. The legendary physicists believed that life on Earth could be quickly wiped out by a disaster, such as an asteroid strike, AI, over-population and climate change. He believed, if our species had any hope of survival, future generations would need to forge a new life in space. Humans must leave Earth within 200 years if we want to survive.

For arguably the most famous physicist on Earth, Stephen Hawking--who died Wednesday in Cambridge at 76 years old--was wrong a lot. He thought, for a while, that black holes destroyed information, which physics says is a no-no. He thought Cygnus X-1, an emitter of X-rays over 6,000 light years away, wouldn't turn out to be a black hole. He thought no one would ever find the Higgs boson, the particle indirectly responsible for the existence of mass in the universe. But Hawking was right a lot, too.

Stephen Hawking, the world-famous theoretical physicist, has died at the age of 76. Hawking's children, Lucy, Robert and Tim said in 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 humour 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 for ever." The most recognisable scientist of our age, Hawking holds an iconic status.

One of the most celebrated physicists of our time, Stephen Hawking, died at the age of 76. The British scientist was known for his pioneering work on black holes and relativity, and has authored several popular books. In 2017, Cambridge University made Hawking's PhD thesis, which he completed in 1966, available to the public. "By making my PhD thesis Open Access, I hope to inspire people around the world to look up at the stars and not down at their feet; to wonder about our place in the universe and to try and make sense of the cosmos," Hawking said in a statement at that time. "Anyone, anywhere in the world should have free, unhindered access to not just my research, but to the research of every great and enquiring mind across the spectrum of human understanding."

LONDON – Stephen Hawking, Britain's most famous scientist, who dedicated his life to unlocking the secrets of the universe, has died at age 76. His children, Lucy, Robert and Tim, said in a statement carried by Britain's Press Association news agency on Wednesday: "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." Born on Jan. 8, 1942 -- 300 years to the day after the death of the father of modern science, Galileo Galilei -- he believed science was his destiny. But fate also dealt Hawking a cruel hand. Crippled by amyotrophic lateral sclerosis (ALS), which attacks the nerves controlling voluntary movement, he spent most of his life in a wheelchair. Hawking defied predictions that he would only live for a few years, overcoming the debilitating effects of ALS on his mobility and speech that left him paralyzed and able to communicate only via a computer speech synthesiser. "I am quite often asked: how do you feel about having ALS?" he once wrote. "The answer is, not a lot.

So far, the only thing I personally associate with A.I. as far as Microsoft goes is Cortana, which continues to be a massive failure. Of course, Microsoft is using A.I. to power other experiences, such as the dynamic albums in the Photos app... but I'd guess most mainstream people don't even know this stuff exists, and this ad doesn't really do anything to help Microsoft's position. But maybe I'm cynical, what do you think?

Physicist Stephen Hawking has died at age 76, according to a family spokesman. Stephen Hawking, the famed theoretical physicist who defied a diagnosis of amyotrophic lateral sclerosis to live virtually his entire adult life with the disease – in a wheelchair and paralyzed but making constant contributions to a world few could understand – has died at age 76, a family spokesman said. Although Hawking may have been incapacitated physically, he managed to write books, including the best seller "A Brief History of Time," teach physics and mathematics, deliver speeches and even float in zero gravity, all while working in the fields of cosmology and quantum gravity. He was not modest about what he wanted to do. "My goal is simple," he once said.

The memory mechanisms of great pond snails could one day help develop drugs for trauma and dementia patients. If you think of a snail, and then think of a human, there are some obvious differences. But decades of studies say our memories might have more in common than some might guess. Memory, and its formation, has been the subject of neuroscientific research for quite some time, yet science has only made incremental steps in this extremely complicated field. One of the recent advances is the discovery that memory is likely similar across organisms, at least at a molecular level.
