1. What are the famous quotes said by Hawking in "A Brief History of Time"

1. The light we see from distant galaxies was emitted millions of years ago Of course, in the case of the most distant objects we see, the light was emitted 8 billion years ago. So when we look at the universe, we are looking at its past. ——Hawking "A Brief History of Time"

2. Why do we never see the broken cups gathering together, leaving the ground and jumping back to the table? The usual explanation is that this violates the second law of thermodynamics. The degree of disorder or entropy in any closed system always increases with time. In other words, it's a form of Murphy's Law: Things tend to get worse: a full cup on the table is a highly ordered state, while a broken cup on the floor is a disordered state. One could easily go from a cup on the table earlier to a broken cup on the ground later, rather than the other way around. ——Hawking "A Brief History of Time"

3. Now we know that any particle has an antiparticle that will annihilate it. (For a force-carrying particle, the antiparticle is itself.) There could also be entire anti-worlds and anti-people made of antiparticles. However, if you encounter someone who is against you, be careful not to shake hands! Otherwise, both of you will disappear in a giant flash of light. ——Hawking, "A Brief History of Time"

4. Before the 20th century, no one had ever suggested that the universe was expanding or contracting. This interestingly reflects the thinking atmosphere at that time. It is generally believed that the universe has either existed in an unchanging state for an infinite period of time, or that it was created in a finite past in more or less the way we see it today. This may be partly due to people's tendency to believe in eternal truths, but also to the comforting notion that the universe must be immortal and unchanging, even though we are subject to birth, old age, illness and death. ——Hawking "A Brief History of Time"

5. On the other hand, philosophers who take it as their duty to find out the roots cannot keep up with the progress of scientific theories. In the 18th century, philosophers considered the entirety of human knowledge, including science, as their domain and discussed questions such as whether the universe had a beginning. However, during the 19th and 20th centuries, science became too technical and mathematical for philosophers, or anyone except a few experts. Philosophers have narrowed the scope of their questioning so much that even Wittgenstein, the most famous philosopher of this century, said: "The only remaining task of philosophy is the analysis of language." This is from Aristotle What a degeneration of the great tradition of philosophy since Kant! ——Hawking "A Brief History of Time"

6. The matter in the universe is composed of positive energy. ——Hawking "A Brief History of Time"

7. All structures in the universe originate from the smallest fluctuations allowed by the uncertainty principle of quantum mechanics. ——Hawking, "A Brief History of Time"

8. Common sense tells us that without external intervention, things will always tend to increase their disorder. ——Hawking "A Brief History of Time"

9. In the infinite universe, there are countless "worlds" being created and destroyed, but the infinite universe itself exists forever. Life is not only on the earth but also on the earth. There are them on the planet, and there may also be them on those distant planets that are invisible. ——Hawking, "A Brief History of Time"

10. God hates naked singularities! ——Hawking, "A Brief History of Time"

11. A good theory must meet the following two requirements: First, the theory must be able to accurately describe a large number of observations - these observations are based on only a few arbitrary Secondly, this theory can make clear predictions about the results of future observations. ——Hawking "A Brief History of Time"

12. Which came first, the chicken or the egg? ——Hawking "A Brief History of Time"

13. In an unchanging universe, the endpoint of time is something that must be given by existence outside the universe; the beginning of the universe has no physical Inevitability. ——Hawking, "A Brief History of Time"

14. Humanity's deepest desire to seek knowledge is enough to provide justification for the continuous exploration we engage in. ——Hawking, "A Brief History of Time"

15. When most people firmly believe in an essentially static universe, the question of whether it had a beginning is really a metaphysical or theological question.

——Hawking's "A Brief History of Time" 2. There should be more good words and sentences about the brief history of time.

Introduce a brief history of time. Good words and sentences. 7. When Einstein said When it comes to "God doesn't play dice", he's wrong. Given the hints black holes give us, God not only rolls dice, but often throws the dice into places we can't see to confuse us. 6. I noticed that even those who claim Everything is predestined and we cannot make any changes. We will be equally cautious when crossing the road. 5. My goal is very simple, which is to complete my understanding of the universe, including why the universe is what it is. and why the universe exists. 4. Someone told me that every time a scientific formula appears in my book, sales will drop by half. When I again put Einstein’s famous formula at the end of the book When E=MC2, I hope not to scare away half of my potential readers. 3. When I was twenty-one, my expectations for happiness had dropped to zero. From then on, any small Happiness can make me feel extremely happy. 2. A boring life is a tragedy. 1.

5. According to Hoyle's theory, an exploding star will release enough heat to create all new elements and scatter it throughout the universe. These elements would form clouds of gas—the so-called interstellar medium—that would eventually coalesce into new solar systems.

6. He did this for no reason, just out of fun. For a long time, those who had the strongest interest in the world's creatures were often the ones most likely to cause their demise. This is a shocking fact.

"A Brief History of Everything" is a scientific work written by American Bill Bryson in 2003. This is an easy-to-understand and fascinating book about the history of the development of modern science. The author uses clear, humorous writing style to record many interesting stories from the Big Bang to the development of human civilization. .

It was selected into the 600 influential books in the 60 years of New China, the 300 influential books in the 30 years of reform and opening up, the 30 outstanding popular science translation books in the 30 years of reform and opening up, and the first place in the reading activities of central state agencies. In the second batch of recommended books, the State Administration of Press, Publication, Radio, Film and Television recommended hundreds of excellent books to young people, and they have also been included in the recommended books for local reading activities by many provinces, autonomous regions, and municipalities.

1. When things go to extremes, they will turn against each other, and when the moon is full, it will lose money. All empires will be destroyed when they expand to the extreme;

2. The big waves wash away the sand, and the natural selection of things makes everything unbearable. Things that have been tested by history will be swept into the garbage heap;

3. True gold is not afraid of fire, and new things that conform to the development of history will thrive under the attacks of the old forces;

4 . From poor families, filial sons emerge, and in troubled times loyal ministers emerge. The darker the age, the more we can see the brilliance of human nature and the value of truth. This is where the hope of mankind lies.

To summarize: History does not advance in a straight line, it rises in a spiral, with twists and turns and repetitions in the middle, but these cannot stop the development of human society. On the contrary, human beings will continue to develop. In these twists and turns, we continue to understand ourselves, improve ourselves, and move towards a higher stage.
