Stephen Hawking, Who Examined the Universe and Explained Black Holes, Dies at 76 (nytimes.com)

Stephen W. Hawking, the Cambridge University physicist and best-selling author who roamed the cosmos from a wheelchair, pondering the nature of gravity and the origin of the universe and becoming an emblem of human determination and curiosity, has died at his home in Cambridge, England. He was 76. From a report: A family spokesman announced the death in a statement to several news media outlets. "Not since Albert Einstein has a scientist so captured the public imagination and endeared himself to tens of millions of people around the world," Michio Kaku, a professor of theoretical physics at the City University of New York, said in an interview. Dr. Hawking did that largely through his book "A Brief History of Time: From the Big Bang to Black Holes," published in 1988. It has sold more than 10 million copies and inspired a documentary film by Errol Morris.

The 2014 film about his life, "The Theory of Everything," was nominated for several Academy Awards and Eddie Redmayne, who played Dr. Hawking, won the best-actor Oscar. Scientifically, Dr. Hawking will be best remembered for a discovery so strange that it might be expressed in the form of a Zen koan: When is a black hole not black? When it explodes.

  1. Farewell, Professor Hawking by 93+Escort+Wagon · · Score: 5, Informative

    His life was remarkable in many ways - one of which was surviving with ALS for so bloody long.

    My dad died from complications of ALS way back in the 1990s. Having seen first-hand how the disease progresses, I marvel at how Hawking managed to live with that disease for so many decades. Yes, they called it "slow onset", but that seems to be mostly a hand-waving attempt at explaining a disease they still don't really understand. Even with support devices like a respirator, it's hard for me to wrap my head around it - those things bring with them their own complications.

    Godspeed, Dr. Hawking.

    Seven reasons we love Stephen Hawking

    Professor Stephen Hawking unexpectedly materialises as The Guide Mark II in the new series of The Hitchhiker's Guide to the Galaxy. "I have been quite popular in my time," he proclaims, and he's not wrong. Here are just seven of the reasons why.

    Well, here you all go since the paywall is breaking things. Stephen W. Hawking, the Cambridge University physicist and best-selling author who roamed the cosmos from a wheelchair, pondering the nature of gravity and the origin of the universe and becoming an emblem of human determination and curiosity, died early Wednesday at his home in Cambridge, England. He was 76.

    His death was confirmed by a spokesman for Cambridge University.

    “Not since Albert Einstein has a scientist so captured the public imagination and endeared himself to tens of millions of people around the world,” Michio Kaku, a professor of theoretical physics at the City University of New York, said in an interview.

    Dr. Hawking did that largely through his book “A Brief History of Time: From the Big Bang to Black Holes,” published in 1988. It has sold more than 10 million copies and inspired a documentary film by Errol Morris. The 2014 film about his life, “The Theory of Everything,” was nominated for several Academy Awards and Eddie Redmayne, who played Dr. Hawking, won the Oscar for best actor.

    Scientifically, Dr. Hawking will be best remembered for a discovery so strange that it might be expressed in the form of a Zen koan: When is a black hole not black? When it explodes.

    What is equally amazing is that he had a career at all. As a graduate student in 1963, he learned he had amyotrophic lateral sclerosis, a neuromuscular wasting disease also known as Lou Gehrig’s disease. He was given only a few years to live.

    The disease reduced his bodily control to the flexing of a finger and voluntary eye movements but left his mental faculties untouched.

    He went on to become his generation’s leader in exploring gravity and the properties of black holes, the bottomless gravitational pits so deep and dense that not even light can escape them.

    That work led to a turning point in modern physics, playing itself out in the closing months of 1973 on the walls of his brain when Dr. Hawking set out to apply quantum theory, the weird laws that govern subatomic reality, to black holes. In a long and daunting calculation, Dr. Hawking discovered to his befuddlement that black holes — those mythological avatars of cosmic doom — were not really black at all. In fact, he found, they would eventually fizzle, leaking radiation and particles, and finally explode and disappear over the eons.

    Nobody, including Dr. Hawking, believed it at first — that particles could be coming out of a black hole. “I wasn’t looking for them at all,” he recalled in an interview in 1978. “I merely tripped over them. I was rather annoyed.”

    That calculation, in a thesis published in 1974 in the journal Nature under the title “Black Hole Explosions?,” is hailed by scientists as the first great landmark in the struggle to find a single theory of nature — to connect gravity and quantum mechanics, those warring descriptions of the large and the small, to explain a universe that seems stranger than anybody had thought.

    The discovery of Hawking radiation, as it is known, turned black holes upside down. It transformed them from destroyers to creators — or at least to recyclers — and wrenched the dream of a final theory in a strange, new direction.

    “You can ask what will happen to someone who jumps into a black hole,” Dr. Hawking said in an interview in 1978. “I certainly don’t think he will survive it.

    “On the other hand,” he added, “if we send someone off to jump into a black hole, neither he nor his constituent atoms will come back, but his mass energy will come back. Maybe that applies to the whole universe.”

    Dennis W. Sciama, a cosmologist and Dr. Hawking’s thesis adviser at Cambridge, called Hawking’s thesis in Nature “the most beautiful paper in the history of physics.”

    How is it that Stephen Hawking won every prize there is except the Nobel? Discovering something revolutionary about black holes would seem to qualify.

    Unfortunately, Hawkings only theorized his signature Hawkings-radiation. Although it is an elegant theory, I don't think anyone has developed a way to validate it yet and the Nobel committee generally isn't persuaded by elegant theories that may or may not turn out to be wrong...

    Also Hawkings has been notably wrong before. He bet against the Higgs particle. He bet that information was lost in a Black Hole. He also wasn't initially convinced that the surface area of a black hole event horizon was a measure of entropy (although Jacob Beckenstein was able to convince him).

    Don't get me wrong, I think he's quite an amazing theoretical physicist in that he has a very good intuition on how things might work, but the physical world doesn't respect intuition about how the world might work, it demonstrates it to us. As a result, not all intuition about the physical world (as elegant as it may be) turns out to be correct about the world in which we actually live...
