Reading "A Brief History of Time"

A world full of mysteries, vast space, giving people endless illusions. Outside the world, the future changes, so amazing! --Inscription

There was a man who defeated the disease and created a miracle. He proved that disability is not an obstacle to success. He used his life to live up to his promises. He struggled for the life he loved. He is the author of A Brief History of Time, Stephen Hawking, the greatest physicist of the 20th century.

Holding this heavy book, I carefully looked at its cover. A large clock first came into view. This clock is very abstract, and the oval dial is deeply recessed in the middle. I think it represents the vast universe, which means there is no end to time. Above the clock is the four golden characters "A Brief History of Time". I slowly opened the book and reveled in the sea of ​​books. Before I read this book, I always thought that it was a very professional science masterpiece. It would definitely be boring and even difficult to read, but I have to change my point now. Mr. Hawking vividly interprets some of the expertise of astronomy in a very humorous language. He compares the expanding universe to a child who eats continuously, and compares stars to salt for eating. A vivid example not only allows you to quickly understand the universe. Knowledge, but also to get a kind of beautiful enjoyment, read and lively and interesting, people can not help but want to read through the book, to satisfy curiosity and curiosity.

Hawking has a famous saying, I deeply remember in my heart, "Body and spirit can not be disabled at the same time." Although his body did not leave the wheelchair for a moment, his thoughts flew out of the earth, flew out of the solar system, flew out of the Milky Way, and flew to the depths of the universe beyond tens of billions of light years away. I admire his enthusiasm for science. He seriously ponders and subtly explains the nature of scientific theory. That is, any physics theory is nothing more than a hypothesis. In this sense, theory is only temporary, and we can never prove it. He is also working on quantum gravity. During his illness, he not only did not get extra rest, but instead used the only rest time to study harder, forgetting to eat, and finally came to the theory of quantum gravity.

He not only has unique insights into quantum gravity, but also a thorough study of the universe's black holes. It can be said that Hawking and Black Hole are in the same name. He first discovered and confirmed that the black hole has temperature and radiation. The temperature of the black hole is gradually increasing during the process of gradual shrinking, and the radiation is continuously enhanced until it finally becomes a singularity, and then gradually increases to cycle.

After reading this book, I fell in love with the universe, as if I was in the vast space, exploring the secrets of the unknown universe. I feel the charm of science. Gorky once said: "To fully love science, because human beings have no power more powerful than science!" Indeed, science is power. Today in the 21st century, what do we rely on to strengthen our national strength, develop our economy, and let China stand in the East? The answer is only science.
