Stephen Hawking, world-famous British physicist, died at the age of 76 at his home in Cambridge, England. The scientist became famous for his work on black holes, relativity and quantum mechanics.
In his most famous discovery, Hawking showed that black holes leak a bit of energy, known as Hawking radiation and then shrink and evaporate.
At the age of 22, Stephen Hawking was diagnosed with ALS, a rare disease of the nervous system. At that time doctors gave him only a few years to live. However, Hawking proved them wrong and fought bravely against his illness. He spent most of his life paralyzed in a wheelchair and was only able to speak through a voice synthesizer.
Hawking was not only a professor at Cambridge University until 2009, but also a popular celebrity who appeared in TV shows like the Simpsons, and the Big Bang Theory. He also wrote a bestselling book about the mysteries of the universe called A Brief History of Time, which sold more than 10 million copies worldwide. His early life was dramatized in the 2014 film “The Theory of Everything“, which received several Academy Award nominations.
Because of him, many ordinary people got interested in physics and the universe. Scientists, politicians and other experts around the world praised Hawking as a person with a brilliant and extraordinary mind.
