Reflection on A Brief History of Time

After reading a classic, I believe you will have many feelings in your heart. You can't just watch. Write a review. Is it impossible to write without a clue? The following are my thoughts on reading A Brief History of Time, for reference only. Let's have a look.

A Brief History of Time 1 A Brief History of Time is a classic book about cosmology written by Stephen Hawking, a great British physicist and the founder of black hole theory and BIGBANG theory. It is a popular science model for popularizing advanced theoretical physics.

"All theories are always temporary: you can never prove it. No matter how many times the results of experiments are consistent with a theory, you can never conclude that the next result will not contradict it. " I came to the conclusion after reading A Brief History of Time. The general meaning of this sentence is that you can never say that all physical theories are true, even if you have guessed them accurately for thousands of times, as long as there are inconsistent inferences next time, then this theory will not be established.

Like I read Marx's motto on the Internet, I think about everything, in other words, the spirit of doubt. The spirit of doubt is the driving force of human progress. Only in this way can civilization progress, otherwise the result it will face will only be stagnation. I have never thought of this idea before.

After reading this book, many questions have been swirling in my mind. Is there a big bang in the universe? Is the universe an infinitesimal point? Will it collapse or eventually stabilize? Is the universe boundless or has an end? Can man invent a time machine to go back in time? All the questions are coming.

Hawking once said: "My goal is simple, that is, to complete my understanding of the universe, including why the universe exists." Including Hawking in 2004 also declared that the black hole theory was wrong. He said: "Black holes are not what he and most other physicists thought before.

The universe is mysterious and dark, but there is such a universe in our hearts!

After reading a brief history of time II. Because teacher Han asked us to read another math story book in the summer vacation, last Sunday, I dragged my father to Shanghai Bookstore to buy books for me. I think: my father, who has always loved mathematics and likes reading books, can definitely choose a suitable book for me. Sure enough, my father immediately picked out a book he liked-A Brief History of Time.

This A Brief History of Time was written by Stephen Hawking. The title of the book is A Brief History of Time, so everything written in the book is naturally related to time. In order to explain time, the author starts with the universe, then talks about space, then talks about black holes, then talks about wormholes, and finally draws a conclusion. The language in the book is full of knowledge and professionalism, which makes me feel very confused. Even so, I seem to know the time. If I talk about time in combination with the words in the book, I will say: time can indeed be material, because everything is material. If time is not material, it will lose its meaning of existence, but obviously, it is extremely important to us, and we can't live without time. Summarize time with an abstruse classic sentence in the book: Time may be immortal, at least in our short-lived material eyes, it is indeed immortal. It produces a point in a specific time and space, so countless points are connected together, become lines, become surfaces, and weave indefinitely until the end of the universe. If the universe is not over, it will continue to weave forever to make the shroud of the creator of the universe.

I don't think this book suits me. After all, I haven't studied physics, and I don't know everything in the book, but I know this is a very important book for us humans. I thought: When I grow up, I will read this book again, and then I can master the knowledge mentioned in the book.

After reading A Brief History of Time, I seldom think about the origin of the universe on weekdays. I know that even if I do, I can't understand it, because my knowledge is not rich enough. The book A Brief History of Time gives me a preliminary understanding of the formation and development of the universe, and also opens another door for my thinking. Although the book is getting more and more confusing at the back, I still try to choose what I like and find interesting.

"The world is a turtle tower with a turtle on it!" The beginning of this book comes from people's misunderstanding of the universe in the past, which leads to what the world is. Through gravity, quantum mechanics shows that the universe is expanding. Then we talked about the formation of black holes and the last wormholes and time travel. Finally, the unity of strong force, weak force and electromagnetic force in physics is summarized.

After reading this book, I feel as if I am not very resistant to physics-related phenomena. I think of the time machine on the edge of the crisis I saw before, and the daughter's hair turned white after her father returned to earth in Star Trek. It seems that there is a rational understanding of these things, not just a perceptual understanding.

Because of my impetuousness, I haven't read all the later chapters, but I obviously feel that I have made great progress this time compared with two years ago, because I didn't work hard when I read the previous chapters, but I also became interested in the middle. Keep refueling (_? )?

Reflections on a brief history of time. Hawking, a familiar name, caught my eye again. His A Brief History of Time has made indelible achievements since its publication, not because the cover of the book is beautiful, nor because there are cartoons in it, but because it can bring us knowledge and the mysteries of the universe. I brought this book today, and it immediately attracted me when I opened it.

In the depths of the magical universe, there is a powerful breath, and that is the magic of black holes. The earth was born as early as 4.6 billion years ago. This book reveals the mysteries of the universe.

At the beginning of the book, we know that the earth revolves around the sun and rotates at the same time, which shows how interesting the universe is. Then he wrote about when the universe began, when it ended, whether there was an end to time, and the evaporation of black holes … many, many, like a Buddhist sutra, which seemed endless.

However, a good article still depends on the author's good intentions. Hawking, the author of this book, is a man who has no physical freedom, but his mind is always free, never bound, and has already flown to the depths of the universe. I want to pay tribute to Hawking, a master who is physically disabled but mentally satisfied!

This book is full of magic and attracts me to read it all the time. You should see it, too!

Reflections on a brief history of time 5. Does the universe have boundaries? When is the universe born and when will it end? What is the essence of time? Can humans catch up with or even surpass the speed of light? Can humans travel through the time tunnel, back to the past or through the future? This series of questions is a mystery in my heart, as if separated by a thin layer of spun yarn, full of mystery. In A Brief History of Time, Mr. Hawking discussed and explained these problems in popular and interesting language. After reading one chapter, he can't wait to read the next chapter. It's really hard to stop!

At first, I didn't understand why A Brief History of Time had such great charm, attracted tens of thousands of readers, was translated into more than 40 Chinese characters, and became popular all over the world. But when I really came into contact with this book, I found Hawking's works so attractive that he explained the difficult cosmological theory in plain language. Under his writing, all strange and incomprehensible theories seem to be funny jokes, attracting the world to explore more and more deeply along his writing.

Taking the theory that the earth is round as an example, the author puts forward two short stories: one is that Aristotle found that the earth cast its shadow on the moon when observing the solar eclipse, and the earth's shadow was always round, because the solar eclipse was caused by the movement of the earth between the sun and the moon. Another experience came from the ancient Greeks, who observed that ships from the horizon always saw the sails first, and then the hull. These two short stories undoubtedly increase the interest of scientific theory. From this, we can see the light from Hawking's intelligent thinking.

Read A Brief History of Time 6 What is the relationship between time and space? What is a black hole? When did the universe begin ... "I have always had these doubts before, and I can't solve them. Until today, after reading A Brief History of Time, I have a thirst in the desert and the joy of suddenly encountering water, and my mystery is instantly solved.

A Brief History of Time is a popular science book. The book is divided into twelve chapters, which tells the whole story of space-time in the universe, explains the physical phenomena such as the expansion of the universe, and makes a scientific analysis of black holes. Let us benefit a lot after reading it. This book does not talk about science stiffly, but uses vivid language to be as easy to understand as possible.

From this book, I deeply understand that science is not far away, it is all around us. However, you should have the courage to ask your own questions, have your own unique opinions, and dare to say, "This is not the case!" Some things seem to be right, but they are actually wrong, but no one has found them. Someone found out, no one dared to say, but there may be only one person who really dared to say "wrong". We should respect science, believe in science and dare to discover science, so as to dare to discover and make mistakes.

Let's remember Hawking, a great man, and let this scientific masterpiece A Brief History of Time last forever.

Is there any speed faster than the speed of light after watching A Brief History of Time 7? Yes, it is the speed of thinking.

This is a term I made up. In the morning, through the huge billboard outside the window, my thoughts can penetrate to the edge of the universe. No, according to the latest theory, the universe has no boundaries and is expanding. Thinking can be expanded accordingly. No one can prove that what you think is right or wrong. That perfect imagination belongs to only one person-yourself.

So happy. Time is meaningless until there is time. Time is an hourglass, which has been used to summarize and diverge since the birth of the universe.

If a great history is only recorded by time, it will eventually be lost. There is too much swelling gravel hidden in time. You are a grain, so am I.

Around a big bend, I lost my desire to tell. Desire is endless. If you are too tired, you will die. This truth is similar to the birth of the theory of relativity and the survival of life.

Einstein's era coincides with the rise of Buddhism in the south. In Buddhism, he can be summarized as "letting go of obsession and making a positive result." This is because: a classic experiment, that is, different observers move in the opposite direction to light and the vertical direction to light on the earth, and the measured light speed is the same. Countless people were immediately deceived. If the speed is equal to the distance divided by the time, then the time measured by relative motion and vertical motion is undoubtedly different. Relative motion will inevitably increase the relative speed, thus reducing the time. Countless people can't get out of this circle. Einstein said loudly: Please don't use distance to push back time, please use time to calculate distance.

Such a gorgeous turn is really imminent. On the edge of the cliff, there is no road. What should I do? What should I do? I thought about it for a long time, but I still stayed put. Turn around.

Great wisdom in the world, if not.

After reading A Brief History of Time, there are too many mysteries in the vast universe. They attract us as firmly as magnets, making us very eager but difficult to explore these mysteries. In this way, an ideological giant appeared, and he was Stephen Hawking. This holiday, I was lucky enough to read his book A Brief History of Time.

When I opened the book, it immediately attracted me deeply. When describing theories such as "Relativity" and "Curved Space", the author uses precise words, is simple and humorous, and does not give people a boring feeling at all.

What's more exciting is that there are many beautiful illustrations in the book to help us understand it. It is also accompanied by the author's bold speculation and speculation about the future universe. Beautiful words seem to put us in the universe again, witnessing the birth and destruction of the Big Bang and the stars ... As the saying goes, "It is better to read for ten years than to listen to a gentleman's words", but I found that after reading A Brief History of Time, the knowledge and essence in the book are better than reading for ten years.

Let's start with Stephen Hawking, the author of this book. The giant in the wheelchair belongs to Hawking. He was confined to a wheelchair for more than 40 years because of "gradually freezing people", but he overcame his physical defects and became an international "superstar". He can't write or even speak, but he transcends the theories of "Big Bang", "Relativity" and "Quantum Science" and enters the vast universe. Although he was so helpless in a wheelchair, his thoughts crossed the earth and flew to the universe.

John milton was right: the mind is his home, where he created heaven and hell. Let's remember a brief history for a period of time, which will be of great help to our life and we will benefit a lot.

A Brief History of Time is a classic book about cosmology written by Stephen Hawking, a great British physicist and the founder of the black hole theory and the BIGBANG theory. It is a popular science model for popularizing advanced theoretical physics.

"All theories are always temporary: you can never prove it. No matter how many times the results of experiments are consistent with a theory, you can never conclude that the next result will not contradict it. " I came to the conclusion after reading A Brief History of Time. The general meaning of this sentence is that you can never say that all physical theories are true, even if you have guessed them accurately for thousands of times, as long as there is an inappropriate inference next time, then this theory will not hold water.

Like I read Marx's motto on the Internet, I think about everything, in other words, the spirit of doubt. The spirit of doubt is the driving force of human progress. Only in this way can you improve your manners, otherwise the result will only stagnate. I have never thought of this idea before.

After reading this book, there are always many questions in my mind. Is there a big bang in the universe? Is the universe an infinitesimal point? Will it collapse or eventually stabilize? Is the universe boundless or has an end? Can man invent a time machine to go back in time? All the questions are coming.

Hawking once said: "My goal is simple, that is, to complete my understanding of the universe, including why the universe exists." Including Hawking in 2004 also declared that the black hole theory was wrong. He said: "Black holes are not what he and most other physicists thought before.

The universe is mysterious and dark, but there is such a universe in our hearts!

After reading A Brief History of Time 10, the vast universe and the mysterious earth all unveiled their mysterious veils one by one.

Stephen Hawking, author of A Brief History of Time. He faced difficulties without fear, overcame diseases and worked miracles. He let us know that defects are not obstacles to success. He used his whole life to realize his promise, and he struggled for his favorite subject all his life. We can say that Hawking is the greatest physicist in the 20th century.

Holding this heavy book full of knowledge, I watched it carefully. The first thing you see is a big clock with an oval dial, and the middle of the dial is deeply concave. Endless time should be its representative. I thought this world-famous popular science book would be boring, maybe a little laborious, but now I have to change my mind.

Mr. Hawking turns complex sentences into humorous language, which helps you quickly understand the knowledge and mysteries of the universe.

I deeply remember Mr. Hawking's famous saying that "if a person has no dreams, he will die". Yes, Mr. Hawking has been confined to a wheelchair for many years, but his thoughts are still active. It flew out of the earth, out of the solar system, out of the Milky Way, and even into the depths of the universe billions of light years away.

Mr. Hawking avoids external interference for various reasons and often thinks about the fate of the universe alone in his room. He can make any sacrifice and give up for his dream and career. Isn't the brilliant achievement he enjoys now bought with sweat and hard work?

After reading this book, I broadened my horizons, and now I find that I only have some little knowledge. Let me fall in love with the mysterious universe and feel the charm of science. Science is power. 2 1 century, how will we strengthen our national strength, develop our economy and make China stand firm in the East? The answer is science.

Comments on A Brief History of Time 1 1 During the May Day holiday, I read a special book-A Brief History of Time. When I opened this book, the vast universe and the mysterious earth came into my eyes. This book is a classic book about the knowledge of the universe written by stephen william hawking, a great British physicist and the founder of black hole theory and BIGBANG theory. It is a popular science model for popularizing advanced theoretical physics. This book aims at popularizing scientific knowledge. It taught us how to look at the world and many strange things around us correctly, and taught us to look at things with a scientific eye, instead of blindly believing in superstitions and other' fallacies' when encountering difficult things.

It was Hawking who explained the formation and destination of the universe! Hawking is really good. He believes that the origin of the universe is an infinite singularity, which was formed by explosion! There are two final destinations: one is the infinite expansion of the universe. The other is that the universe expands first, but it will shrink to a certain extent, and finally it will become an infinitesimal singularity with infinite density, that is, the universe will circulate indefinitely!

Hawking is a man of strong will. Although he can only move three fingers, he still keeps exploring and has a persistent spirit to reveal the mysteries of the universe for us.

A Brief History of Time is really a good book, which can not only teach others knowledge, but also make people think and feel!

After reading A Brief History of Time, we all know that magic is a very magical thing, and the universe is like a huge magic hat, full of infinite possibilities.

Bertrand Russell once gave a speech about how the earth revolves around the sun and how the sun revolves around the center of a huge group of stars that we call galaxies. After the speech, an old woman said, "The world is actually an infinite turtle tower." Most people find it ridiculous, but in any case, only time will tell.

As early as 340 BC, the Greek philosopher Aristotle was able to put forward two good arguments for the argument that the earth is a sphere rather than a flat plate in his Theory of Heaven. First of all, he thinks that the solar eclipse is caused by the earth moving between the sun and the moon. Because the shadow of the earth on the moon is always round, this is only true if the earth itself is spherical. But if the earth is a flat disk, unless the solar eclipse always happens when the sun is just below the center of this disk. Secondly, the Greeks learned from their travels that the farther south they look at the starry sky, the greater the difference in the position of Polaris between Egypt and Greece. Aristotle even estimated that the length of the earth is about 4,000,000 stidia. The Greeks even provided a third argument for the fact that the earth is spherical. Otherwise, why do ships coming from beyond the horizon always show their sails first and then their hulls?

The magic and unpredictable universe, its charm will attract more scientists to explore.

A Brief History of Time 13 This winter vacation, I read a book called A Brief History of Time, written by Stephen Hawking, the smartest person in the world.

This whole book is about the knowledge of the universe and also involves time. Its greatest feature is that at the back of the book, several famous scientists are introduced: Einstein, Galileo and Newton, who have made great contributions to cosmology. The whole book tells us the image of the universe and the relationship between the universe and time. One of the most attractive is the mystery of black holes. Black holes are composed of large mass, high density and strong gravitational fields, which can prevent light from escaping.

Reading the whole book, I think science is very important. Human life cannot be separated from science, because science can make human life happier. Without science, there would be no fast and convenient transportation, no room with constant temperature in all seasons, and no interesting games without science ... Now all signs say "Chinese dream, my dream", and the basis of these "dreams" is science.

I remember that there is a sentence in the general preface of the book that "there is no scientific' education', just to cultivate faith, not education." People who have not received science education can only be called trained, not educated. "I think this is completely correct. If education is a bus that enables people to acquire knowledge, then science education is a private car that enables people to acquire knowledge.

Hawking is self-reliant, bold in exploration and bold in reasoning. His scientific spirit is worth learning. I recommend you to read A Brief History of Time, and I believe you will feel the same way.

After reading a brief history of time 14, I read a book these days. To be honest, I really didn't understand much. However, I still tried to read every paragraph over and over again, and I got a little harvest. When reading two chapters of A Brief History of Time, I was deeply impressed by two points: First, modern physics seems to be more legendary than Zeus, Jehovah and Pangu in ancient Greek mythology.

There is another feeling that has made me think for a long time, that is, I can't imagine how abnormal Mr. Hawking is, just as I can't imagine what four-dimensional coordinates with time look like. He can do it with a bent body and a twisted face, as if he just blinked and made a "buzzing" sound. But a brief history of time proves that all this is not an obstacle.

I suddenly realized that I had two feet and one hand. I can walk, write, laugh and run around. Physically, I am much richer than Mr. Hawking, but he can achieve so much. What do I need? In this case, don't fail a math problem and don't be afraid in front of the English test paper. Shun is also, Anto is also, if you are promising.

A Brief History of Time 15 Today, I read A Brief History of Time by the famous general relativity and cosmologist Stephen Hawking. After reading it, I benefited a lot and had mixed feelings. ...

This brief history of time mainly tells the history and future of the universe, the essence of time and space-time, black holes and other awesome themes. Hawking, with his keen intuition and firm reasoning, directly challenged the widely recognized traditional quantum science, the Big Bang theory and even Einstein's theory of relativity. In the unfinished business of exploring the elusive secrets of the core of time and space, it will guide people all over the world who like to look up at the stars to explore the secrets of the universe.

Hawking was born in 20xx. At the age of 2 1, he unfortunately suffered from Lou Gehrig's disease, which led to muscle atrophy, so he was confined to a wheelchair and only three fingers could move. In 20xx, he underwent tracheal puncture because of pneumonia, and completely lost the function of speaking. Speech and question-and-answer can only be done by a speech synthesizer. It is such a man who finished the book A Brief History of Time in a wheelchair, and his indomitable spirit is really admirable. He suffered unimaginable pains and hardships, but he completed a brief history of time in a wheelchair with unyielding perseverance. I really can't express my admiration for his spirit and perseverance in words.

Hawking's disability, I will never forget it until I die! He wrote the most brilliant stroke in the history of life with his perseverance! I will never forget his spirit!
