Stephen Hawking, in full Stephen William Hawking, (born January 8, 1942, Oxford, Oxfordshire, England—died March 14, 2018, Cambridge, Cambridgeshire), English theoretical physicist whose theory of exploding black holes drew upon both relativity theory and quantum mechanics. He also worked with space-time singularities.
What is the disease of Hawking?
Hawking was diagnosed with Amyotrophic Lateral Sclerosis (ALS), commonly referred to in the U.S. as Lou Gehrig’s disease. As ALS progresses, the degeneration of motor neurons in the brain interfere with messages to muscles in the body. Eventually, muscles atrophy and voluntary control of muscles is lost.
Why is Stephen Hawking in a wheelchair?
Hawking lived with amyotrophic lateral sclerosis (ALS), or Lou Gehrig’s Disease that impacts movement, and used a wheelchair most of his adult life. He was diagnosed with the neurological disease at 21 and was given only years to live.
How is Stephen Hawking a genius?
1) He invented black holes* What Hawking did was increase our understanding of what a black hole is. Through his mathematical theorems, Hawking was able to “prove” exceptions in Einstein’s theories of gravity. His work showed that there were points in the universe where those gravitational theories broke down.
What did Stephen Hawkings discover?
Dr. Hawking is best known for his discovery that black holes emit radiation which can be detected by special instrumentation. His discovery has made the detailed study of black holes possible. Stephen Hawking was born in Oxford, England on January 8, 1942.
What was Hawking’s theory?
In 1971, Stephen Hawking proposed the area theorem, which set off a series of fundamental insights about black hole mechanics. The theorem predicts that the total area of a black hole’s event horizon — and all black holes in the universe, for that matter — should never decrease.
How did Stephen Hawking talk?
How did Stephen Hawking talk? Hawking previously used his finger to control a computer and voice synthesizer. But once he lost use of his hands, he started depending on twitching a cheek muscle to communicate. Whenever the cursor reached a word or phrase he wished to use, Hawking twitched his cheek muscle to select it.
