Stephen Hawking 70, Lou Gehrig ('s Disease) 0

From all of us here at Big Think, Happy 70th birthday, Stephen! If you had only been one of the smartest humans ever, it would have been enough – but you're something much bigger than that: a model of how to live.

"My advice to other disabled people would be, concentrate on things your disability doesn’t prevent you doing well, and don’t regret the things it interferes with. Don’t be disabled in spirit, as well as physically." 

– Stephen Hawking

There's an old, endless Passover song that rattles off, one by one, all the good things Jehovah did for the Jewish people – parting the Red Sea, etc – following each item with the refrain Dayenu ("It would have been enough"). It would be easy to compose an updated, secular version about Physicist Stephen Hawking, each of whose extraordinary accomplishments in the 50 years since he was diagnosed with ALS, or Lou Gehrig's disease, would have been more than enough for an ordinary lifetime. Consider his groundbreaking work in quantum physics, his breathtaking A Brief History of Time, which sold 10 million copies to at least 9 million people who didn't understand a word of it, his 30-year tenure as the Lucasian Professor of Mathematics at Cambridge University – a post once held by Sir Isaac Newton. 

Dayenu, Dayenu, Dayenu.

Add to these the fact that Hawking has achieved most of this in a state of almost total physical immobility, confined to a wheelchair and able to communicate only by twitching his cheek muscles to select words on a computer screen, and that he still has enough of a sense of humor to be thrilled about appearing in cartoon form on the Simpsons, and you are left either deeply inspired or reeling at your own petty gripes and narrowness of vision.

Stephen Hawking DJs on the Simpsons. Note the bling.

Let's choose inspiration. Formulating a single sentence can take Hawking as long as ten minutes, yet he has written nearly two dozen books (including a guide for the disabled and, with his daughter Lucy, a children's book) and starred in Into the Universe, a documentary which he also wrote. He communicates daily via email with physicists all over the world, and insisted on doing a 2011 New York Times interview in person, in spite of debilitating complications from pneumonia that have left him needing round-the-clock care since 2009. Far from indulging in self-pity, though, Hawking considers himself lucky that his day job is to ponder the secrets of the universe. Painstaking though the work must be, he spends every day doing exactly what he loves to do.

The Longest Living Survivor of ALS (Lou Gehrig's Disease)
Amyotrophic Lateral Sclerosis, or ALS, is a degenerative motor neuron disease that leads to paralysis and death, usually within five years of diagnosis. Hawking has lived and worked for 50 years with the disease – a complete mystery to ALS experts, some of whom argue that Hawking's illness may not be ALS at all. Although he can't personally take credit for his extraordinary longevity, it is yet another of his groundbreaking achievements.

So, from all of us here at Big Think, Happy 70th birthday, Stephen! If you had only been one of the smartest humans ever, Dayenu – but you're something much bigger than that: a model of how to live.

A Brief History of Stephen Hawking

Jan 8 1942

Born in Oxford, England.

1953 to 1958

Attends St Albans school in North London, and becomes fascinated with mathematics. 

1959 to 1962

Specialises in physics at University College Oxford. Graduates with a first class degree in natural sciences.


Begins research in cosmology and general relativity at the University of Cambridge. Diagnosed with ALS.


Discovers a remarkable property: by using quantum theory and general relativity he is able to show that black holes can emit radiation.


Joins the department of applied mathematics and theoretical physics at Cambridge.

In the same year he discovers, to his disbelief, that black holes could leak energy and particles into space, and even explode in a fountain of high-energy sparks.


His breakthrough discovery is published in the journal Nature, in a paper entitled Black Hole Explosion?


Appointed Lucasian professor of mathematics at Cambridge (a chair held by Sir Isaac Newton in 1663). Elected as a fellow of the Royal Society.


Publishes A Brief History of Time: From the Big Bang to Black Holes, a classic introduction to today's most important scientific ideas about the cosmos. Recorded in the 1998 Guinness Book of Records as an all-time bestseller.


Publishes Black Holes and Baby Universes, and other Essays, a collection of scientific articles exploring ways in which the universe may be governed.


Publishes Stephen Hawking's Universe: The Cosmos Explained, a book about the basis of our existence and of everything around us.


Releases Universe in a Nutshell in the UK, a book that unravels the mysteries of recent breakthroughs in physics.


Releases On the Shoulders of Giants, The Great Works of Physics and Astronomy, an exploration of some of the greatest visionaries in the history of science including Copernicus, Kepler, Galileo, Newton and Einstein.

Publishes The Theory of Everything: The Origin and Fate of the Universe, a book that presents the most complex theories of physics past and present. 


Hawking announces that he has solved the Black Hole paradox, which has been a troubling scientists for years. He presents his most recent findings at the international conference on general relativity and gravitation in Dublin.


Publishes God Created the Integers and A Briefer History of Time 


A statue of Hawking by renowned late artist Ian Walters is unveiled at the Centre for Theoretical Cosmology, University of Cambridge.


Awarded the Presidential Medal of Freedom, the highest civilian honor in the United States.

Why a federal judge ordered White House to restore Jim Acosta's press badge

A federal judge ruled that the Trump administration likely violated the reporter's Fifth Amendment rights when it stripped his press credentials earlier this month.

WASHINGTON, DC - NOVEMBER 16: CNN chief White House correspondent Jim Acosta (R) returns to the White House with CNN Washington bureau chief Sam Feist after Federal judge Timothy J. Kelly ordered the White House to reinstate his press pass November 16, 2018 in Washington, DC. CNN has filed a lawsuit against the White House after Acosta's press pass was revoked after a dispute involving a news conference last week. (Photo by Alex Wong/Getty Images)
Politics & Current Affairs
  • Acosta will be allowed to return to the White House on Friday.
  • The judge described the ruling as narrow, and didn't rule one way or the other on violations of the First Amendment.
  • The case is still open, and the administration may choose to appeal the ruling.

How to split the USA into two countries: Red and Blue

Progressive America would be half as big, but twice as populated as its conservative twin.

Strange Maps
  • America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
  • Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
  • Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America

Scientists just voted to change the definition of a kilogram

The definition of a kilogram will now be fixed to Planck's constant, a fundamental part of quantum physics.

Greg L via Wikipedia
Surprising Science
  • The new definition of a kilogram is based on a physical constant in quantum physics.
  • Unlike the current definition of a kilogram, this measurement will never change.
  • Scientists also voted to update the definitions of several other measurements in physics.
