Reflections on the mysteries of the universe

After reading a work, I believe everyone must understand a lot. It's important to record it. Let's write a review. So how should I write my thoughts after reading? The following are my thoughts on the mysteries of the universe, which I sorted out. Welcome everyone to refer to it, I hope it will help you.

After reading The Mystery of the Universe, I feel that the universe is full of unknowns, which makes me curious. The book Mystery of the Universe solved the puzzles for me one by one.

Open the book and the eight planets will come. Gorgeous Saturn, blue earth, warm orange Mars and sea blue Mercury are displayed one by one, as if they were in an unpredictable, beautiful and magical universe, magnificent and beautiful! The Mystery of the Universe taught me what magnitude is, and the brightness of stars is also different. Let me know how solar and lunar eclipses are formed and how planets are born. Let me stay in the galaxy where we live-the Milky Way, the spiral Milky Way, like a giant wheel embedded in a silver plate, and like a shining white ribbon floating in the wind in the deep blue night sky, which satisfies my great curiosity and thirst for knowledge.

The Mystery of the Universe also introduces the ancient people's research and understanding of the universe in China, such as "Huntian Theory" and "Michelle Ye Theory". "Huntian theory" holds that the sky is like a sphere, the ground we step on is half of the sphere, the ground is the other half of the sphere, and the sun and stars revolve around it. The ancient West also had its own views, such as "geocentric theory" and "Heliocentrism". Heliocentrism was put forward by Copernicus, which correctly reflected the actual situation of the solar system. It thinks that the sun is the center of the universe, the earth and mercury revolve around the sun, and the moon and the earth revolve around the sun together.

After reading this book, I feel the power of science. Without science, there would be no civilization. Science comes from generations of unremitting exploration of nature. They are diligent in thinking, persist in observing and experimenting, dare to challenge authority, and even sacrifice their lives for truth. For example, Bruno was burned alive in Rome Square and preached "Heliocentrism". It is precisely because of the scientific understanding of the universe that the mechanical theories of Galileo, Newton and others have come into being, and today's space shuttle, artificial satellite and so on have brought great changes to our lives.

In fact, there are sciences everywhere in our lives, such as why mirrors let us see ourselves, why magnifying glasses can magnify things, why plants have various colors, and why the sky is blue. ..... By studying, observing and thinking, we can find many things that we are used to, but unexpected, and make you full of discovery fun. It is in a series of "why" that we learn a lot of science around us and know this magical world.

Reflection on the Mystery of the Universe 2 I read an article today, which made me feel very sorry. It is called "Venus War". This article mainly talks about Venus. Mars. The earth is brothers and sisters, they are very similar, and they all have a life course. The reason is that facestones, dry river beds and a small amount of oxygen have been found on Mars. City ruins and stone faces were found on Venus. Why are there city ruins on Venus? It turns out that there was a nuclear war on Venus before. A country launched a nuclear weapon to compete for territory, but this kind of nuclear weapon ignited the hydrogen in the ocean, causing global explosion and extinction!

My feeling is that Venusians are so ignorant that they started a war and detonated nuclear weapons, so that some innocent Venusians there perished. We earthlings must never wage war, let alone launch nuclear weapons like Venusians. Although we earthlings have had wars and done stupid things before, as long as we don't wage wars like before, the whole world can become friends and live in harmony, and we can let bygones be bygones, because people should learn to be tolerant!

Reflections on the Mysteries of the Universe 3 When I finished reading the book Mysteries of the Universe, I felt that there were too many mysteries of the universe. Since ancient times, the vast universe has been the most fascinating place for human beings, and the vastness of the universe is still unimaginable for ordinary people. As the source of all our energy and the foundation of all our lives, the sun is already huge for our understanding ability, but compared with the universe we observe now, it is only a drop in the ocean.

17 18, astronomer Harley found that the positions of the three brightest stars-Sirius, Nanhesan and arcturus-were very different from those recorded by astronomers in the Greek era, and could not be normal errors, so he concluded that these stars were not stationary, but moving quite slowly, because they were quite far away from us, so they seemed to be stationary. /kloc-in the 0/9th century, people found that stars in the universe have different spectra, so some people asked whether stars also evolved. The answer to this question was not found until the 1950s. During this period, American astronomer Schwarzenegger combined the energy and structure of stars with the evolution of stars through systematic research. Huo Yier gave a scientific explanation for the evolution of stars, and divided the life cycle of stars into several stages, such as origin, main sequence star, red giant star and dwarf star. Among them, the star stays in the main sequence star stage for the longest time, and our sun is now in this stage. Scientists use Hertz-Rototo diagram to describe the evolution of stars. The study on the evolution of stars is by far the most accurate scientific research on celestial bodies.

Cosmic science is a history that transcends people's sense of sureness step by step. Every new discovery is accompanied by people's sense of surprise and disbelief. The solution to almost every difficult problem will lead to more challenging new problems from relevant evidence. In order to acquire this knowledge, human beings have been working hard for centuries. Every achievement is a ladder of continuous progress, and the discovery of every difficult problem is a challenge to intelligence. ...

The development of cosmic science is full of the charm of rationality and logic, and it also leaves endless imagination space for human beings. Students, work hard! Explore more mysteries of the universe in the future ...

Reflections on the Mystery of the Universe 4 During this holiday, I read the book Mystery of the Universe. This book is about scientific secrets and explains a series of questions such as "why the stars shine" and "why the sea is blue". Around every question, Dr. Weird Humor will give an imaginative and weird answer first, which makes people laugh. Then the intelligent and knowledgeable Professor Zach will give correct and detailed answers to let the children know more scientific knowledge and truth.

After reading this book, I know that there are eight stars in our solar system, namely Mercury. Venus. Earth. Mars. Jupiter. Saturn. Uranus and Neptune. Among them, the nearest to the sun is Mercury. The farthest from the sun is Neptune. Jupiter is the largest and Mercury is the smallest.

Stars are huge stars much bigger than the earth. Stars are made of gas. In the center of a star, such as the sun, the temperature can reach 15 million degrees. At this temperature, the gas will burn and release a lot of light and heat to the surrounding area. This is why the stars shine.

This book not only inspired me to understand science, but also learned a lot of knowledge, so I suggest everyone read it.

Reflections on the Mysteries of the Universe 5 Today, I finished reading the book Mysteries of the Universe and Nature, and the sixth chapter, Animal Paradise, left a deep impression on me. Bees fly, animals walk, fish swim, insects sing, birds turn around, and nature is full of vitality and excitement because of these creatures.

Have you ever heard of the magical legend of dinosaurs? Have you ever seen the spectacular sight of Ma Benteng shaking? Can you imagine a furious python swallowing a whole calf? From the scorching equator to the icy Antarctic and Arctic, from the unfathomable seabed to the snowy peaks, from the winding gullies and rivers to vast expanse and the inaccessible land, there are traces of animals everywhere.

The Sphinx in Egypt, the image of the unity of man and beast in ancient Greek mythology, and the mermaid legend in Andersen's fairy tales ... It is no exaggeration to say that animals have endowed human beings with many strange ideas. Thanks to the inspiration of animals, we invented radar, researched and manufactured electronic frog eyes, and finally realized the beautiful dream of soaring in the sky for thousands of years ... It is undeniable that animals have played an important role in the process of human civilization.

Do you know that?/You know what? Do you know that?/You know what? Like us humans, the animal world is full of love and warmth. Animals, like humans, have dark sides, such as coldness, selfishness, impetuousness, hostility and intrigue. This is another mysterious world. Let's go into the animal world, look for their traces and explore their secrets; To know the soul of this life, to know the spirits of nature, and to protect the closest friends of mankind.

Thinking about the mysteries of the universe 6 I read a book about the science of the universe today, which describes that the universe is made up of countless stars, planets and satellites of planets. One of the blue planets rotates around the clock, and this is our earth.

This book made me understand that the sun is a glowing star. Without the sun, everything on the earth can't survive. Where did the sun go when night fell? That's because the earth revolves around the sun and also rotates like a top. The side facing away from the sun is daytime, and the side facing away from the sun is night.

Tell me how the rocket got into space, how man landed on the moon ... I understand how astronauts eat, have their hair cut and go to the toilet on the space station. The space shuttle can accommodate large satellites or transport raw materials needed to build a space station. It also has a mechanical arm that can move satellites or other artificial objects to designated positions.

This summer, Shenzhou-9 was successfully launched at Jiuquan Satellite Launch Center, and its return capsule landed safely ten days later. I was very excited to see the astronauts' uncles and aunts coming out of the return capsule. Make up your mind in your heart, study hard now, be an astronaut when you grow up in the future, set foot on a spaceship and explore the mysteries of space!

After reading the mysteries of the universe, seven books are bosom friends, and books are reading materials that accompany you all your life. It can be said that books are the ladder of our progress. Without books, it is like without light.

I found this book when I went to the warehouse to clean up, because many years have passed. There was a layer of dust on it, and I shook. Tossing around, I saw that the paper had turned yellow and there were bookworm pupae everywhere. Take it back to the bedroom in the afternoon and open it. There are many records about UFOs and secrets of the Milky Way, as well as information about black holes ... I couldn't help being fascinated by the meat in the book, which lasted for an afternoon.

Just when I was about to finish reading it, the next page had been torn off. I watched the flying saucer on page 87 be torn off ... hey!

This is what I felt when I read The Mystery of the Universe. In the future study and life, I must also read more extracurricular books to increase my knowledge.

After reading "The Mystery of the Universe", I took time to read the children's encyclopedia-The Mystery of the Universe, which is a wonderful color version of knowledge reading, consisting of 167 knowledge short articles. From the origin of the universe, the general situation of the earth and the moon, the formation of meteor shower and the space exploration of manned spacecraft are discussed from the characteristics of the nine planets in the solar system. This is a vivid and interesting picture.

Through reading, I learned that the sun, the earth and the moon are the three major planets in the universe, of which the sun is the largest and a star, which can emit powerful light and heat; The earth is smaller than the sun, is a planet, and does not shine; The moonlight that people see is reflected by the sunlight on the moon.

The book describes many interesting astronomical phenomena, such as a partial solar eclipse when the moon covers part of the sun; The moon covers the center of the sun, like a halo, called an annular eclipse; A total solar eclipse is when the sun is completely blocked. Meteor shower is formed by the thermal radiation of comets to the sun, and it is named after the constellation where the radiant point is located, such as Leonid meteor shower and Gemini meteor shower.

Of course, I am most interested in the introduction of astronauts landing on the moon in space. The moon is the closest celestial body to the earth, with a volume of only 1/49, a mass of 1/8 1 and a gravity of only 1/6. It's this moon. Since ancient times, many poets and painters have described it with wonderful pen and ink, and many folk fairy tales have been circulated, which also makes young me full of reverie about this planet.

Although I don't quite understand many scientific principles, for me, this book is a vivid enlightenment of cosmic science, which not only broadens my horizons, but also enriches my feelings.

Reflections on the Mystery of the Universe 9 The Mystery of the Universe was published by Baya Youth Publishing House, France. The main characters are Doctor Strange, Miss Zuzu and Professor Zach.

Doctor Strange's answer in the book is very interesting, and Professor Zach corrects Doctor Strange's answer. The questions in the book include: why space is black, how the stars are born, what is a meteorite, why the moon shines, what is the ozone layer, what is a light year, what is a starry sky, what is weightlessness ... what is a meteorite? Doctor Strange answered this question like this. He said, "Martians like bowling. Only on Mars, they can't play with metal balls like earthlings, so they only play with stones found on Mars. The problem is that Martians are not as smart as humans. They hit the stone hard on the ground, and it bounced back and flew into space. In space, the earth is below Mars, so these small balls that fly away from Mars will eventually rush to the earth. Those little balls lost by Martians are what we call meteorites! "

After reading this book, my harvest is that science is an indispensable thing in our life.

After reading The Mystery of the Universe, Stephen Hawking, a giant in a wheelchair, is a top theoretical physicist. Although his body is confined to a wheelchair and only his fingers can move a little, he travels in the vast universe with his mind. Because of this, he is also known as the most famous scientific thinker and the most outstanding physicist in the world after Einstein.

Hawking's works are numerous, and The Universe in the Shell is another wonderful astronomy science secretary after A Brief History of Time. At first glance, the title is a bit strange. In fact, it comes from the opera Hamlet, in which the protagonist Hamlet sings that even if he shuts himself in a shell, he still thinks he is the king of infinite space. But so far, it is not clear who is the king of infinite space. Modern quantum cosmology regards the origin of the universe as the evolution of a shell-like instanton, and the quantum folds of this shell contain the codes of all structures in the universe. But for ordinary people, this is unimaginable.

I am interested in this book, not only because of its metaphorical title, but also because of its unremitting exploration of space. Because of the illustrations, this book is profound, but it is not too boring. Moreover, when I see theoretical modeling, I will be inexplicably excited. I seem to have suddenly entered just visiting, quietly watching the achievements of generations of scientists exploring the universe. These seven seemingly independent chapters, in this book, exude unique charm and let us know the more mysterious side of the universe. Of course, there are too many secrets in the universe, and what we know is only the tip of the iceberg.

The first chapter, A Brief History of Relativity, tells that Einstein, a scientific giant, laid the foundation of relativity and quantum theory before Hawking. The curvature of time and space mentioned in it is impressive, and this theory is also called general relativity. Before that, the theory without gravity was called special relativity. 19 19, when the British expedition to west Africa observed the solar eclipse, it was observed that the light was slightly deflected due to the approach of the sun. The general theory of relativity has been well proved. This is also direct evidence of the curvature of time and space. But it is a pity that Einstein made an incorrect judgment on this conclusion, which also made him feel sorry.

It has become an indisputable fact that the universe is expanding and galaxies are moving away. The black hole theory makes people feel how wonderful the universe is, but the fifth chapter is more fascinating to protect the past. The topic of "time travel" is absolutely interesting. Wormhole, an imaginary time tunnel, seems to be a complete paradox from the logic of "grandfather paradox": what would happen if you went back to the past and killed your grandfather before your father became pregnant? This is really a test of logical thinking, and a novel adapted from a movie "Time Machine" I saw before also touched on this problem. And I can't imagine what it would be like for them to have computers in the Roman Empire. However, scientific exploration will develop and break through in the process of constantly putting forward assumptions and doubts.

Although I have read this book carefully, its professionalism makes it difficult for me to understand, and the content is only a little understood. But it did take me into a new space of the universe that I had never touched before, and my understanding of the universe was deeper. The mystery of the universe is being revealed by human beings bit by bit. I firmly believe that one day we will see the whole universe. Not just looking up at the stars on earth!
