After reading 1, I took time to read the children's encyclopedia-The Mystery of the Universe, which is a wonderful knowledge reader with colorful pictures and consists of 167 short knowledge articles. From the origin of the universe, the general situation of the earth and the moon, the formation of meteor showers and the space exploration of manned spacecraft from the characteristics of the nine planets in the solar system. It is lively and interesting, with pictures.
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.
My mother bought me a book called The Mystery of the Universe, which was edited by Li Jiyong. This book is divided into five chapters.
The first chapter is the evolution of the universe. The contents of the book tell me that the universe is boundless, and its age is about 65.438+0.37 billion years. Astronomers are using satellites and telescopes in space to observe and explore the mysteries of the universe.
In the second chapter, I appreciate the magic of space. In the third chapter, our solar system, I learned that there are planets in the solar system. It turns out that there are nine planets in the solar system, including the earth and Pluto. The nearest is Mercury, and the largest is Jupiter. In 2006, Pluto was kicked out of the Planets. At present, there are eight planets in the solar system, which revolve around the sun constantly. The sun keeps burning, providing light and heat for our earth. The earth where we live is spherical. It revolves around the sun. The revolution and rotation of the earth's four seasons day and night. Another good friend of our earth is the moon, which is a satellite of the earth. There is no water or air on the moon.
The fourth chapter is the wonder of the starry sky. In this chapter, I learned that stars are graded according to their brightness. Planets were discovered by scientists through observation and data calculation. Halley's comet is beautiful in appearance but ugly in heart. Meteor showers are mainly formed by the movement of comets.
In chapter five, I met several scientists when I solved the mystery of the universe. Newton discovered the "law of gravity" inspired by the fall of apples, and solved the mystery of "the moon will not fall". 1609, the great scientist Galileo invented the astronomical telescope, and for the first time, human beings had insight into the universe. After understanding some mysteries of the universe and mastering some related knowledge, we humans invented artificial satellites and launched them into space with rockets to help our daily lives. The most common are communication satellites, meteorological satellites and navigation satellites.
The book The Mysteries of the Universe is very good. There are not only written descriptions in the book, but also rich and exquisite color illustrations, with illustrated words beside them. The rich and exquisite color illustrations deeply attracted me and made me interested in reading this book, from which I got to know great scientists and learned some mysteries of the universe.
I think reading and studying is a very meaningful thing, and I can learn a lot of new knowledge from books. I want to make friends with books and form a good habit of loving reading from an early age.
Reflection on exploring the mysteries of the universe at night, looking at the stars in the sky always makes me daydream. I can't help but think of this magical universe. Many questions surround my mind, but one of them is a desirable one, all of which are dissolved in the book Exploration of the Mysteries of the Universe.
This book mainly explains the mysterious mysteries in the universe and the great contributions made by unknown scientists. The birth of the universe, the ancient people's cosmic consciousness, colorful stars and so on, these problems are all shown in this book. Those mysterious, profound and ulterior secrets are all revealed in this book. My first book, Exploring the Mysteries of the Universe, vividly shows the unique charm of the universe, making people feel as if they were there. It is rich in astronomical knowledge, which adds a beautiful landscape to our voluminous books. Moreover, this book not only broadens our knowledge, but also improves our thinking ability.
I love this universe very much. It is amazing and huge, but what is broader is the minds of those scientists and their persistent and never-say-die spirit of exploration. This is exactly what we should learn. What we lack in studying now is a persistent attitude. Not paying attention to homework, watching TV and playing computer are all my bad habits. I can only succeed if I have perseverance.
At the same time, I understand the importance of extracurricular reading. In this book, I not only have a lot of knowledge that can be used well in my life, but also can be used in my study, which makes my knowledge more extensive. Similarly, those mysteries in the universe also make me full of confidence in my ideal. Just like my name, my ideal is to be an astronomer. I believe I will be an excellent astronomer when I grow up.
The universe is full of unknowns and makes me curious. The book Mystery of the Universe solved the puzzles for me one by one.
Open the book, here come the eight planets. Gorgeous Saturn, blue earth, warm orange Mars and sea-blue Mercury are all displayed in front of us, as if they were in an unpredictable and beautiful 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.
Reflections on the exploration of the mysteries of the universe 6 books are close 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.
Thinking about exploring the mysteries of the universe, Hua said: "scientific inspiration can never wait." If there is any accidental opportunity for scientific discovery, then this "accidental opportunity" can only be given to educated people, people who are good at independent thinking, people who have perseverance, and not to lazy people. "
Open the mystery of the universe, let us feel science, let our thoughts fly to that magical and dreamy universe and feel the mystery of this magical and dreamy universe.
This book was written by Stephen Hawking. In this book, the author answers the basic questions about the universe with a brand-new material theory, and introduces the complex universe physics to the readers in a very easy-to-understand language for the first time. This book presents the secrets of exploring time and space with a large number of photos and three-dimensional and four-dimensional space maps made by computers. This book expounds a big problem, that is, from BIGBANG to black holes. Hawking believes that his lifelong contribution is to prove the inevitability of black holes and big bang singularities under the framework of classical physics. He pointed out that under the framework of quantum physics, black holes became smaller and smaller due to radiation, and the singularity of the Big Bang was not only erased, but the whole universe also started from here.
The universe is the floorboard of everything in the world. The universe is divided into condensed structure universe and dissipative structure universe, and condensed structure universe is lifeless. At that time, the universe was a huge black hole with the strongest central energy, and the "physical universe" was explained by physical phenomena. It has no boundaries in space and no beginning and end in time. Some are what people see, that is, "the observed universe", and most of them are beyond people's reach. People often have such a question, that is, "Where do people come from?" Why are there people on earth? Scientists' exploration also started from the origin of human beings. As we all know, we humans live on the earth, where the earth exists is the solar system, and the solar system is in the Milky Way. So where is the Milky Way? The answer is the universe.
From the universe to cosmology, but what is cosmology? This is an old topic. As higher animals, we are not satisfied with the extension of our own life and race. Generation after generation has been tirelessly exploring the meaning of life. Of course, human evolution is extremely slow. From Aristotle-Ptolemy's geocentric theory to Copernicus-Galileo's Heliocentrism, scientists have spent thousands of years exploring and made some new scientific achievements after many years. According to cosmology, the farther a galaxy is from us, the faster it is from us. It goes back to ancient times along the origin of history. It is estimated that an epoch-making event happened between 654.38 billion and 20 billion years ago, that is, the universe was born from an extremely dense and extremely hot state by a big bang. Thought of here, I can't help but think of China's ancient myth "Pangu created the world", so maybe after the distant ancient times, people have initially understood the mystery of the universe. No, this is an eternal mystery.
Bing Xin said: "The depth of the soul is the depth of the universe and the resting place in the brilliant light. Where to find the infinite mystery? After a smile, before words, there is infinite mystery. The matter in the universe is too complicated, and there are many things that we humans have not explored. With the passage of time, too many mysteries have been solved, but the exploration of the universe so far is a great mystery, both for mankind and the whole world.
The dissipative universe is the life universe. Therefore, if the universe is scattered, it will live, and if it gathers, it will die; And life is to gather and live, but to disperse and die. This is the dialectical unity of the universe and life.
The mystery of the universe is endless, which makes people think;
The universe is mysterious and unpredictable;
The mystery of the universe is fascinating and amazing;
It is sacred and ancient, but it is always a mystery. ...
Reflections on the exploration of the mysteries of the universe 8 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 Exploring the Mysteries of the Universe 9 During this holiday, I read the book Mysteries 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 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 exploration of the mysteries of the universe 10 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, and the curvature of time and space mentioned in it is impressive, and this theory is also called general relativity, while the theory without gravity before this is 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!
Reflections on Exploring the Mystery of the Universe 1 1 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.
Reflections on the Exploration of the Mysteries of the Universe 12 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, hatred of wealth 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.
Reflections on the exploration of the mysteries of the universe 13 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!
