The day when Hawking was born was the 300th anniversary of Galileo, another great scientist, and today when Hawking died happened to be Einstein's birthday in March 14. Sometimes, history is such an amazing coincidence, only the subject of accident, and it is two great scientists in human history.

Hawking is regarded as the greatest physicist after Einstein. He proved the singularity theorem and black hole area theorem of Einstein's general relativity, and put forward the evaporation phenomenon of black holes and Hawking's infinite universe model.

? He made great contributions to unifying the two greatest basic theories of physics in the 20th century-Einstein's theory of relativity and Planck's quantum mechanics. Einstein once fundamentally changed some basic concepts such as space and time with the sword of reason, and revealed the unity of matter and motion (equivalence of mass and energy). Einstein's most important contribution in his life is relativity, that is, the unified field theory of gravity and electromagnetism.

Hawking, as the most famous physicist and cosmologist, is the research director of the Center for Theoretical Cosmology of Cambridge University. Although he suffered from amyotrophic lateral sclerosis and was paralyzed for many years, he had to rely on a speech synthesizer to communicate with others.

? However, it did not hinder the creation of his most famous book "A Brief History of Time: From the Big Bang to the Black Hole", which has been on the bestseller list of the Sunday Times for 237 consecutive weeks. Hawking often expressed his personal views on life, human beings, nuclear weapons, aliens and other issues before his death, and often caused heated discussions on the Internet. It can be said that this physically disabled but still struggling scientist has become a contemporary popular science network.

? Life is unfair, no matter what your situation is, you can only go all out.
