Professor Stephen Hawking is the greatest scientific thinker after Einstein. Under his leadership, we embarked on the exploration of the universe by scientists for centuries. With his wisdom and enthusiasm, Professor Hawking gave the most detailed and clear explanation of the most complicated theories, which made us realize how humans gradually understand the characteristics of planets, stars, galaxies, the universe and even matter.

In the 1970s, he and Penrose proved the famous singularity theorem, for which they both won the Wolf Prize in Physics of 1988. He is therefore known as the most famous scientific thinker and the most outstanding theoretical physicist in the world after Einstein. He also proved the area theorem of black holes. Hawking's life is very legendary, and he is one of the most outstanding scientists in history in scientific achievements.
His position is the highest professorship in the history of Cambridge University, and he is a member of the Royal Society. Although he is so helpless in a wheelchair, his thoughts have brilliantly crossed the vast space and time to solve the mystery of the universe.
Cosmology is an ancient and young subject. It took 2000 years to evolve from Aristotle/Ptolemy's geocentric theory to Copernicus/Galileo's Heliocentrism. Surprisingly, although people know that everything in the world is moving, it was not until Hubble discovered the law of red shift in the 1920s that the concept of the evolution of the universe entered human consciousness.
Hubble found that it can be inferred from the red shift of the galaxy spectrum that the farther the galaxy is from us, the faster it is from us, which indicates that the whole universe is expanding. It is estimated that there was an epoch-making event from10 billion to 20 billion years ago, that is, the universe was born from an extremely dense and extremely hot state by the Big Bang.
Hawking believes that the contribution of his life lies in that, within the framework of classical physics, the inevitability of black holes and big bang singularities has been proved, and black holes are getting bigger and bigger; However, under the framework of quantum physics, he pointed out that black holes became smaller and smaller due to radiation, and the singularity of the Big Bang was not only smoothed out by quantum effects, but the whole universe also started from here.
Freud's ultimate achievement lies not in psychology, but in encouraging the development of literature and art. stephen william hawking endowed cosmology with artistic temperament. He makes black holes a part of daily life, arouses people's curiosity, enriches human spiritual life and breaks the tendency of dehumanizing science. We look up at the starry sky, a vast unknown field.
Stephen Hawking 1942 1.8 was born in Oxford, England. His father Frank and his mother Isabel both studied at Oxford University. Frank majored in medicine, while Isabel studied philosophy, politics and economics. After the outbreak of World War II, Frank originally wanted to serve the country from the army. His superiors thought that he could make more valuable contributions to the country if he engaged in research, so he worked as a researcher in a medical research institute, where Isabel also found a job as a secretary.
They met, fell in love and tied the knot here. After their marriage, they lived in Haegert, a suburb near London. When Nazi Germany bombed Britain, London was attacked almost every night. The couple were forced to decide that Isabel should move to safer Oxford to have a baby. Isabel didn't return to Heigert until Stephen was born. When Stephen 1 was five years old, they also gave birth to two daughters, Filipa and Mary. When Stephen/Kloc-was 0/4 years old, they adopted a son, Edward.
Once, he fell down the stairs and landed on his head first, causing a slight temporary amnesia. At Cambridge University, the situation got worse, and his speech was a little vague. Hawking's parents also noticed his health problems and took him to see an expert. At the age of 2 1, the doctor diagnosed amyotrophic lateral sclerosis. He had only two years to live, but two years passed and he was still alive.
In the late 1960s, Hawking's physical condition began to deteriorate again, and he had to walk and move with crutches, so he could no longer teach regularly. As Hawking gradually lost his writing ability, he developed an alternative visual method. He has formed various mental models and mental equations in his mind, and he can use these mental elements to think about physical problems. Physicist Werner? Israel said that Hawking's thinking process is just like Mozart's unique symphony written by imagination.
Hawking doesn't want to bow to evil diseases or even accept any help. He likes to be considered a scientist, then a popular science writer, and most importantly, a normal person with the same desire, motivation, dreams and ambitions as others.
Hawking's speech function is declining year by year. By the end of 1970s, only his family or close friends could understand him. In order to talk to others, he must rely on an interpreter. Hawking's office building has no ramp specially designed for wheelchairs, and Cambridge University is unwilling to pay the funds needed to build the ramp for the disabled, so Hawking and Cambridge have a dispute.
Together with his wife, he launched an activity to urge Cambridge University to improve facilities for the disabled. However, Hawking's attitude towards playing the spokesman for the rights of the disabled is usually ambiguous. On the one hand, he wants to help the disabled, on the other hand, he wants to separate himself from the disability and the challenges that come with it. His attitude caused some criticism.
