Part One: Introduction of New Course

Stephen Hawking was born in Oxford, England, on January 8, 1942. This is a special day. Galileo, the founder of modern science, died on the same day 300 years ago.

After graduating from Oxford University, Hawking went to Cambridge University for graduate school. At this time, he was diagnosed with "Lou Gehrig's disease" and soon became completely paralyzed. In 1985, Hawking underwent tracheal surgery due to pneumonia. After that, he was completely unable to speak and relied on a small intercom and language synthesizer installed in his wheelchair to talk to people; when reading, he had to rely on a machine that turned the pages of the book. When documenting, you need to ask someone to spread out each page on a big table, and then he drives the wheelchair to read page by page like a silkworm eating mulberry leaves...

It was in this unbelievable difficulty for ordinary people that Hawking became a world-recognized giant in the science of gravitational physics. Hawking holds the Lucasian Chair Professor of Mathematics at Cambridge University, where Newton once served. His black hole evaporation theory and quantum cosmology not only shocked the world of natural science, but also had a profound impact on philosophy and religion.

From the singularity of the Big Bang to the radiation mechanism of black holes, Hawking made outstanding contributions to the development of quantum cosmology. His goal is to solve the "first thrust" problem that has troubled mankind since Newton. His universe model is a closed, boundless, limited four-dimensional space-time, and the evolution of the universe depends entirely on the laws of physics.

In Chinese, "yu" means "up and down, four directions" and represents space; "zhou" means "throughout the ages" and represents time. The history of the universe is the process of space development in time. Stephen Hawking uses time as the order to study the birth and development of the universe we live in, as well as its possible future conditions. Therefore, he called his book "Time" "A Brief History" is actually "A Brief History of the Universe".

Reading article·Appreciation and summary (1-6)

1. What should I explain first?

First show your confidence in predicting the universe

2. The theme of this speech is to predict the future of the universe. Why does the opening chapter (1-5) list some embarrassing events where wizards have repeatedly failed to predict?

Through comparison, it is shown that the predictions of wizards lack scientific basis and are just ambiguous judgments. The real skill lies in explanation. This is very different from scientists' predictions.

The future of the universe PPT, part 4: summary of language art style

What are the language characteristics of this speech?

humorous

As a speech about the future of the universe, a large amount of this article is about serious scientific topics and uses a lot of professional terms, which can easily make people feel boring. But Hawking's cleverness lies in the fact that he used a lot of humorous language to make such an academic speech aimed at explaining scientific principles so that people can listen carefully in a relaxed and pleasant atmosphere. There are many such words, such as: "Fortunately, counting people's names seems to take a long time." "You can't actually predict the numbers, otherwise, physicists would make a fortune in the casino." "Even if the universe is going to collapse, I can predict with confidence that it will not stop expanding for at least 10 billion years. I don't foresee that I will be around to be proven wrong by then." "If the inflation theory is correct, Then the universe is literally on a knife's edge. So I'm following in the good tradition of those wizards or prophets who place bets on both sides to make sure nothing goes wrong."
