The Empty Chair: World Pays Tribute to ‘Rare Genius’ Stephen Hawking Dead at 76

Tributes have started to pour in for Stephen Hawking, the modern British physicist and author who has died aged 76. R.I.P Stephen Hawking 1942-2018.

Hawking was considered a ‘rare genius’ and modern cosmology’s brightest star.

Astronauts, scientists and celebrities celebrate the life of a ‘colossal mind and wonderful spirit’.

Sir Tim Berners-Lee, founder of the world wide web, was one of the first to respond to news of his death, saying on Twitter: “We have lost a colossal mind and a wonderful spirit”.

Nasa also tweeted, saying: “his theories unlocked the universe of possibilities that we & the world are exploring.”

“May you keep flying like superman in microgravity.”

“Remembering Stephen Hawking, a renowned physicist and ambassador of science. His theories unlocked a universe of possibilities that we & the world are exploring. May you keep flying like superman in microgravity, as you said to astronauts on @Space_Station in 2014,” NASA tweeted.

The Planetary Society said: “farewell to a beautiful mind”, while astrophysicist Neil deGrasse Tyson shared a photo of himself and Hawking. “His passing has left an intellectual vacuum in his wake,” he wrote.

Satya Nadella, the CEO of Microsoft, wrote: “we lost a great one today”.

As news of Hawking’s death spread, images of an empty wheelchair were shared on social media.

Many scientists shared their encounters with Hawking over the years. Harvard astrophysicist Jonathan McDowell remembered Hawking’s determination to deliver a lecture despite struggling to speak.

“I recall when we has giving lectures and it was a huge effort for him to speak (before the tracheotomy and the computer voice) he still made the effort to throw jokes in. That says something.”

US astronaut Chris Hadfield, lamented his death saying: “Genius is so fine and rare. Goodbye Professor Hawking. You inspired us all.” Fellow astronaut Scott Kelly said Hawking’s death was “a loss for all humanity”.

Tributes also came from the entertainment industry. The Foo Fighters said he was a “fucking legend”, while actor Macaulay Culkin paid tribute to “a genius and my favorite Simpsons character”.

Singer Katy Perry noted that Hawking died on Pi Day, the annual celebration of the mathematical constant pi, writing “there’s a big black hole in my heart.”

British TV presenter Jonathan Ross said: “the world just dropped a lot of IQ points.”

Hawking was not only one of the most brilliant scientists of his age but also symbolized the ability of the human spirit to rise above severe physical disability.

For the final few decades of his life motor neurone disease left him paralysed and unable to speak unaided. His life depended on round-the-clock nursing and he communicated via a computer-driven synthetic voice. Yet he became internationally renowned not just for his work in theoretical physics but for his skills in communicating complex cosmological concepts to the general public.

His book A Brief History of Time became the best-selling science book ever written.

Hawking’s self-proclaimed intellectual goal was strikingly ambitious: “Complete understanding of the universe, why it is as it is and why it exists at all.” He made important contributions to many of the big issues in cosmology, particularly the unification of the two great theories of 20th-century physics: relativity and quantum mechanics.

His most original research concerned black holes — concentrations of matter so dense that light cannot escape from their gravitational pull. He showed that black holes are not just a bizarre theoretical concept but play an important role in the development of the universe. Indeed, they are not even quite black; they can emit radiation — known as Hawking radiation — and eventually they can even evaporate and disappear.

Hawking emerged as a leading populariser in 1988 with the publication of A Brief History of Time. Although his disability made writing a slow and laborious process, he went on to produce several other popular books, including Black Holes and Baby Universes (1993) and The Universe in a Nutshell (2001).

At the same time, he emerged as an immensely popular lecturer who could fill any auditorium with fans eager to hear his elegant voice-synthesised account of the cosmos. He inspired thousands of young people with enthusiasm for research.

Stephen William Hawking was born in Oxford on January 8, 1942 — as he liked to point out, this was 300 years to the day after the death of Galileo. His father was a tropical diseases specialist and his mother a Liberal party activist.

He won a scholarship from St Albans School to read physics at University College, Oxford. Then he moved to do a PhD in cosmology at Cambridge university, where he was to spend the remainder of his professional life.

His motor neurone disease (also known as ALS) was diagnosed in his first year at Cambridge. It kills most people within two years but Hawking proved to be a most remarkable survivor, helped by his first wife Jane Wilde, whom he married in 1965 and by whom he had two sons and a daughter.

Hawking’s condition deteriorated over the years and took a marked turn for the worse in 1985, when he caught pneumonia and had a tracheostomy operation. After that, he lost all power of speech and depended on 24-hour care from teams of devoted nurses.

Fortunately technology had by then reached the point at which Hawking could communicate by computer, using tiny movements of his hand, eye or head to select letters and words. These could be saved to disk or spoken out via a speech synthesiser.

By the 1990s Hawking had become a big-name celebrity and the tabloid newspapers feasted on the acrimonious break-up of his marriage and his wedding in 1995 to Elaine Mason, who had been one of his nurses.

His celebrity status irked some scientists, who mocked A Brief History of Time as the most bought and least read science book of all time. They said that, while he was an imaginative cosmologist, statements by admirers that he was the best scientific mind since Einstein were over the top.

Whether Hawking would have made such an impact with his science if he had not suffered from motor neurone disease is impossible to say — and beside the point. It was the combination of disability and scientific brilliance that made him a great man.
