Stephen Hawking (Physicist, Scientist)

(1942 - 2018) 
Stephen Hawking is known for his work regarding black holes and for authoring several popular science books. He suffers from amyotrophic lateral sclerosis.



Synopsis

Stephen Hawking was born on January 8, 1942, in Oxford, England. At an early age, Hawking showed a passion for science and the sky. At age 21, while studying cosmology at the University of Cambridge, he was diagnosed with amyotrophic lateral sclerosis. Despite his debilitating illness, he has done groundbreaking work in physics and cosmology, and his several books have helped to make science accessible to everyone. Part of his life story was depicted in the 2014 film The Theory of Everything.
Early Life and Background


The eldest of Frank and Isobel Hawking's four children, Stephen William Hawking was born on the 300th anniversary of the death of Galileo—long a source of pride for the noted physicist—on January 8, 1942. He was born in Oxford, England, into a family of thinkers. His Scottish mother had 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.

Stephen 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 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 (1943) and Philippa (1947). 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."
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 was also frequently on the go. With his sister Mary, Hawking, who loved to climb, devised different entry routes into the family home. He remained active even after he entered University College at Oxford University at the age of 17. He loved to dance and also took an interest in rowing, becoming a team coxswain.
Hawking expressed a desire to study mathematics, but since Oxford didn't offer a degree in that specialty, 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 Cambridge University for a PhD in cosmology.

Disability outreach

Since the 1990s, Hawking has accepted the mantle of role model for disabled people, lecturing and participating in fundraising activities. At the turn of the century, he and eleven other luminaries signed the Charter for the Third Millennium on Disability which called on governments to prevent disability and protect disability rights. In 1999 Hawking was awarded theJulius Edgar Lilienfeld Prize of the American Physical Society. Motivated by the desire to increase public interest in spaceflight and to show the potential of people with disabilities, in 2007 he participated in zero-gravity flight in a "Vomit Comet", courtesy of Zero Gravity Corporation, during which he experienced weightlessness eight times.
In August 2012 Hawking narrated the "Enlightenment" segment of the 2012 Summer Paralympics opening ceremony. In 2013, the biographical documentary film Hawking, in which Hawking himself is featured, was released. In September 2013, he expressed support for the legalisation of assisted suicide for the terminally ill. In August 2014, Hawking accepted the Ice Bucket Challenge to promote ALS/MND awareness and raise contributions for research. As he had had pneumonia in 2013, he was advised not to have ice poured over him, but his children volunteered to accept the challenge on his behalf.

Appearances in popular media

At the release party for the home video version of the A Brief History of Time, Leonard Nimoy, who had played Spock on Star Trek, learned that Hawking was interested in appearing on the show. Nimoy made the necessary contact, and Hawking played a holographic simulation of himself in an episode of Star Trek: The Next Generation in 1993. The same year, his synthesiser voice was recorded for the Pink Floyd song "Keep Talking", and in 1999 for an appearance on The Simpsons. Hawking appeared in documentaries entitled The Real Stephen Hawking (2001) Stephen Hawking: Profile (2002)  and Hawking (2013), and the documentary series Stephen Hawking, Master of the Universe (2008). Hawking has also guest-starred in Futurama and The Big Bang Theory. Hawking allowed the use of his trademarked voice in the biographical 2014 film The Theory of Everything.
Hawking has used his fame to advertise products, including a wheelchair.

Awards and honours

Hawking has received numerous awards and honours. Already early in the list, in 1974 he was elected a Fellow of the Royal Society (FRS). At that time, his nomination read:"Hawking has made major contributions to the field of general relativity. These derive from a deep understanding of what is relevant to physics and astronomy, and especially from a mastery of wholly new mathematical techniques. Following the pioneering work of Penrose he established, partly alone and partly in collaboration with Penrose, a series of successively stronger theorems establishing the fundamental result that all realistic cosmological models must possess singularities. Using similar techniques, Hawking has proved the basic theorems on the laws governing black holes: that stationary solutions of Einstein's equations with smooth event horizons must necessarily be axisymmetric; and that in the evolution and interaction of black holes, the total surface area of the event horizons must increase. In collaboration with G. Ellis, Hawking is the author of an impressive and original treatise on "Space-time in the Large". The citation continues:
