Mainly: How did the universe come into being? Where did it start and where will it end? What is the nature of the universe? Why are humans here? Why do stars shine? This is a journey of discovery full of surprises. Following the footsteps of the discoverers and exploring the mysteries of the universe will give you a brand-new understanding of human existence and everything around you.
Professor Stephen Hawking is the greatest scientific thinker after Einstein. Under his leadership, we embarked on the exploration journey 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 theory, which made us realize how human beings gradually understood the characteristics of planets, stars, galaxies, the universe and even matter.

In the 197s, he and Penrose proved the famous singularity theorem, for which they won the 1988 Wolf Prize in Physics. 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 was so helpless in a wheelchair, his thoughts traveled brilliantly to the vast space and time to solve the mystery of the universe.
Cosmology is an ancient and young subject. It took 2 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 redshift in the 192s that the concept of the evolution of the universe came into human consciousness.
Hubble found that it can be inferred from the red shift of the galaxy spectrum that the farther the galaxy is, the faster it will leave us, which indicates that the whole universe is expanding. It is estimated that there was an epoch-making event between 1 billion and 2 billion years ago, that is, the universe was born from an extremely dense and extremely hot state by the Big Bang.
Hawking believes that his life contribution is that in the framework of classical physics, it proves the inevitability of black holes and big bang singularities, and black holes are getting bigger and bigger; However, in 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 also the whole universe started here.
Freud's ultimate achievement lies not in psychology, but in encouraging the development of literature and art. Stephen william hawking endowed the study of cosmology with artistic temperament. He made black holes a part of daily life, stimulated people's curiosity, enriched human spiritual life, and broke the tendency of dehumanizing science. We look up at the starry sky, the vast unknown territory.
stephen hawking was born in Oxford, England on January 8th, 1942. 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 work, so he worked as a researcher in a medical research institute, and Isabel also found a secretarial job in this research institute.
They met here and fell in love and tied the knot. After their marriage, they lived in Heigert, a suburb near London. At that time, the Nazi Germans bombed England, and London was attacked almost every night. The husband and wife were forced to decide that Isabel should move to safer Oxford to give birth to the baby. It was not until Stephen was born that Isabel returned to Heigert. When Stephen was 1 and 5 years old, they also gave birth to two daughters, Filippa and Mary. When Stephen was 14 years old, they adopted a son, Edward.
On one occasion, he fell down the stairs and landed on his head first, causing a slight temporary memory loss. At Cambridge University, the situation worsened, and his speech was somewhat vague. Hawking's parents also noticed his health problems and took him to see a specialist. At the age of 21, doctors diagnosed him with amyotrophic lateral sclerosis, and he had only two years to live, but two years flew by and he was still alive.
In the late 196s, Hawking's physical condition began to deteriorate again, and he had to use crutches when walking and walking, so he could no longer teach regularly. As Hawking gradually lost his writing ability, he developed an alternative visual method. He formed various mental patterns and mental equations in his mind, and he could use these mental elements to think about physical problems. Physicist Werner? Israel said that Hawking's thinking process was like Mozart's writing a unique symphony just by imagination.
Hawking doesn't want to bow to the evil disease or even accept any help. He likes to be regarded as a scientist, then as a popular science writer, and most importantly, as a normal person with the same desires, drive, dreams and ambitions as others.
Hawking's speech function declined year by year. By the late 197s, only his family or close friends could understand him. In order to talk to others, he must rely on an interpreter. At the entrance of Hawking's office building, there is no disabled ramp specially designed for wheelchairs, and Cambridge University is unwilling to pay the money needed to build the disabled ramp, so Hawking has a dispute with Cambridge.
He and his wife * * * launched an activity to urge Cambridge to improve facilities for the disabled. However, Hawking's attitude towards playing the role of 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 accompany it. His attitude caused some criticism.
