With the development of Internet, various TV programs have been integrated into our lives. At this time, we might as well turn our experiences into words and write a review record. If we want to understand the true meaning of the work, we might as well write a review. Simply stating the relevant contents of the original text is also a way to write comments. What format should I use to write a work review? To this end, we took the time to sort out the reflection of the universe, thank you for your reference.

What is the universe? 1? How big is the universe? This problem has puzzled us for thousands of years, and until now there are still many things unknown to the world.

When I was a child, I always thought that the earth was already very big, otherwise we wouldn't be able to hold billions of people. Of course, sometimes I also think about some questions: What is the universe? How big is the universe? Is the earth the largest? The last question seems to be somewhat contradictory to the former, but it is not, because the former is my childhood idea and the latter is the present problem. With these thoughts and questions, I entered the world of what the universe is.

In What is the Universe, I know the beginning of time and the end of the universe, and show me our home in the universe, the solar system, and the deeds of astronomers who discovered everything.

What is the Universe dispels my doubts, but there are a few more questions: How many galaxies, how many planets, how many black holes, how many lives and how many possibilities are there in the universe? These problems will never be solved, but they also give me another dream: to be an astronomer and solve the mysteries of the universe. They also told me that the universe is full of wonders, and the mystery of the universe may never be solved. However, as long as we work hard, work hard and work hard again, there will be no unsolved mysteries, insurmountable difficulties and insurmountable sufferings! Let's solve the mystery of the universe!

Cosmic Reflection 2 I first got this book in Shanghai and "grabbed" it from President Li Qiu. When I saw the author's name, I searched the author's profile: clinical psychologist and psychotherapist. A famous Japanese psychologist. Because one of the authors of The Power of Picture Books is also Kazuo Hehe, what impressed me at that time was that we had three opportunities to contact picture books in our lives-when we were young, when our children were young, and when we were old. The content of the book is very grounded. So, when I picked up the book Children's Universe, I began to read it seriously.

The book is a psychological case, which discusses the relationship between children and their families, secrets, animals, time and space, the elderly, death and the opposite sex, so as to guide adults how to approach the universe in children's hearts. At the beginning of the book, it is also said that there are children in this universe, which is known to all. However, do you know that every child has a universe in his heart? It exists with infinite breadth and depth. Adults are often blinded by children's small appearance and forget this vast universe. Adults are so eager to let their children grow up that they distort the vast universe inside their children and even destroy it irretrievably. I have read this passage several times in order to further understand its meaning. In fact, it is even more unacceptable to think that such terrible things are often carried out in the name of "education", "guidance" and "goodwill" declared by adults.

Children make new discoveries every day. But not everyone will tell adults. This book also reflects this content in Children and Secrets, and makes us adults realize that there will be some secrets that belong to children's hearts during their growth, and these secrets are very important to children, and even will be of great help to their healthy growth. This reminds me of a sentence that my child said to me half jokingly after work. Of course, it is: Mom, my hobbies have been killed by your reality. When I heard this sentence, I was really shocked. I didn't expect the child to say that after work. We must seriously reflect on it in the later stage. Because I also know what my son wants to express. Because children have performed well in painting since kindergarten, the composition and color matching of each painting make people feel very comfortable. I like it when I grow up. After school, I often participated in literary and artistic activities organized by the school, and once wanted to study this kind of major. Just because of my so-called thoughts and interference, I failed to do it. But what is certain is that my son's psychology is healthy. He is always sunny and satisfied with his present job. When you grow up, telling me this is also a release and release of inner secrets! What I can give my children now is only encouragement and some affirmation at work, so that they can get different gains at work.

Taking "children and their families" as an example, this paper interprets children's psychological world and talks about the "running away from home" behavior caused by children's inner "self-care consciousness". Children also find that the outside world is not as calm as they think, that is, they can't support themselves to live independently. The well-known picture book Feifei is angry is also a story about psychological cases. Although there is not much expression in the text, it is similar to the performance of children in reality. The ingenuity of picture book stories lies in the integration of children's universe and nature, and presents the content of children's self-control with a seemingly short story. All these aspects also imply that we adults should regard children as an important member in many things and understand their needs and ideas. Pay attention to what children need for their growth and what kind of help they need.

The whole book "Children's Universe" is from a psychological perspective. Although I still can't understand some places, this book also gives me a great feeling that we can't impose our so-called love on our children. In the process of growing up with children, we just think of a role that connects the child's heart with the outside world. So is preschool children. As a kindergarten teacher, don't treat children as a blank sheet of paper. Many times, you have to squat down and talk to the children. Many times, you can sit quietly with your children without even saying too much. Pay more attention to children's universe and be a guide to children's hearts. Learning to try to change practices and statements may have different effects.

Reflection on the Universe Chapter 3 This book, no matter what its content is, just saying its author is enough to shock and admire people. The writer is Steven, a professor at Cambridge University. Mr hawking. He is a quantum physicist with only three fingers moving all over his body. It was with these three fingers that he wrote one book after another with the mouse. A Brief History of Time is his masterpiece.

The first chapter of "The Universe in the Shell" mainly introduces general relativity and special relativity, and how Einstein made further thinking and research on their basis, and also expounds Hawking's own views.

The second chapter talks about a hypothesis. The author assumes that time has a shape, and verifies that this assumption is consistent with relativity through quantum formula.

In the third chapter, the author is explaining the universe.

He believes that the universe has many heavy histories, and each history can be composed of tiny particles; The fourth chapter tells a prediction. Mr. Hawking predicted that in a state of supergravity (such as a black hole), time is curved, so how can we lower ourselves to adapt to the future? In the last two chapters, the possibility of traveling in time and space as creatures and our relationship with the universe are drawn up by using various conditions in the universe, and assumptions such as whether the place where we live is empty are also put forward.

The content of this book gave me a great shock. I won't be confused when I encounter other strange problems after reading it.

In the third quarter of Chapter 4 of Cosmic Reflection, the author first told a story called "King of Donkey Ears".

Besides, there is a king. Later, somehow, his ears became very long, like those of a donkey. The king thought it was a shameful thing and wanted to cover up this feature. What he did was to wear a hat. He thinks that he can cover up this feature, and he thinks it would be very shameful if this feature is known by the people. However, this king always needs a haircut, so after every haircut, the king will kill the barber. Oh, hey, there's finally a barber begging for mercy. He promised to keep a secret. Alas, the king promised to let him go. But when the barber kept this secret, he got a strange disease. No way, he found a fortune teller, and the fortune teller said, alas, you may not have said it, but you suppressed it. Guess what? Go outside the city and tell the willow not to be heard. The barber thought, well, that makes sense. So he sneaked out of the city and began to shout at the willow tree, "The king's ears are donkey's ears." Have you finished shouting? Hey, you're fine! Oh, but it's not that simple. Later, whenever the wind blows on this willow tree, alas, that willow tree will make a sound: "the king's ears are the ears of the donkey." Hey, great, the whole country knows. Alas, the king had no choice but to take off his hat. Oh, what a surprise. I didn't expect this public to have more respect for such a king.

The author said, firstly, it is too painful and difficult for this barber to keep a secret. I finally had to get sick. What about the second one? Why did the king kill the barber? Alas, the author said from a psychological point of view, alas, the barber means to change his hairstyle. But the king, he wants to hide such a shortcoming, he doesn't want to change his personality and improve it. So, he wanted to kill the barber who wanted him to change clothes. Third, from the king's point of view, alas, the king thinks this is a shameful thing, so he naturally wants to be conservative, and he thinks he can be conservative. In order to protect him, he had to stifle many feelings and interpersonal relationships, stifle such opportunities for his growth, and stifle many things. However, in front of nature, no matter how hard one tries, he can't fight against it, so the king finally has to admit that he has to take off his hat to pay tribute to nature, knowing that it is impossible to succeed if he tries hard to play. Unexpectedly, this characteristic of him has become a channel for ordinary people to love and respect him, not as contemptuous as he thought at first. Even so, the author also said that when, with whom and in what way to disclose this secret, we should be cautious.

Next, the author told two stories, one about secrets. A story is about a little girl who was almost harassed by that hooligan when she was five years old. As for this matter, she dare not tell anyone, nor can she say it, but she didn't expect such an experience and such a secret to bring a lot of misfortune to her life growth. Until she was 30 years old, when she got married, something happened in her marriage, which was very painful. So, alas, she made up her mind to tell her mother about this experience. How did you know? Mom said in a sarcastic tone, "Why do you say this at such a big age?" God, in the face of his mother's ridicule, this man actually feels abandoned by the whole world. Soon after, she took her own life. The author said that for this child, her experience is a great thing for her, which condensed all her horror and incomprehension, which is hard to say. Even she is not a physical and spiritual experience, but an experience related to a person's survival and existence. This is a very important matter.

The author said that the second story is about a man and a mother whose child was adopted. Alas, when the child reached the second year of high school, his grades suddenly dropped, and he was very upset. As for the mother, it seems that the child should know that she is adopted, but some people say that she should not hide it, others say that she should hide it, so she doesn't know what to do. All right, let's find this author. The author said to himself, well, I can't make a choice for you. Well, it's your responsibility, so he didn't give his mother a clear opinion. He just said that although such adoption is inevitable and reasonable, it is difficult to accept and feel it from the perspective of children. Therefore, at this point, it is very important for the author to give her a suggestion on the extent to which you can have sex with your child. Later, the parents took very good measures. He called adoptive parents and biological parents together with their children and explained frankly why they wanted to adopt. At the same time, I sincerely apologize for the' great pain' brought to the children because of such a thing. Then it became very harmonious. Therefore, the author particularly emphasizes that when sharing secrets, we must be fully prepared for the painful and sad feelings that accompany this process.

Through the comparison of these two stories, the author clearly shows a secret, ah, under what conditions should it be made public, and it cannot be made public easily. This story, well, these three stories: the king with donkey ears, this girl who had an experience when she was five years old, and this adopted son. What do these three stories have to do with our children

First, think that there may be many secrets of one kind or another in the process of children's growth. So what kind of attitude do we adults have towards such a secret? Ah, how to face it?

Second, if you have some secrets from your family, how can you share them with your children?

Third, when we are outside, what kind of guiding attitude should we have, or when and with what kind of people should we disclose some secrets in the whole family. Because as long as it is the secret of this family, if it is not handled properly, it will eventually leave something behind. That result may be difficult for us to face.

Today, I finally finished reading The Universe in the Shell written by Hawking. Although I read it from beginning to end, and I usually read it four or five times in the middle of a sentence, I still have a little knowledge of the content, but I still have to write down my thoughts after reading it. ...

After reading this book, I think it should be related to another book written by Hawking, The Origin and Destination of the Universe. Because theory of everything mentioned in The Origin and Destination of the Universe (combining all local theories into a "theory of everything", if found according to Hawking's words, it will be the end of theoretical physics and the ultimate victory of mankind) is the M theory mentioned in The Universe in the Shell (also called string theory). Among them, M theory includes 0- alien, type I, IIB, IIA, E- alien and 1 1 dimensional supergravity. Among them, 1 1 dimensional supergravity, P film, M theory, quantum mechanics, general relativity, 10 dimensional film, superstring and black hole are designed. The center of linking these things in M theory is the goal that needs to be found in today's research. Hawking thinks that people live in the space of 10 or 1 1, but people don't realize that the extra dimension is as small as Planck's scale (Planck's length is 10-33 cm, and Planck's time is 10-43 seconds) or as large as infinity.

It is generally believed that the universe is expanding, because the Doppler effect and microwave radiation received from the universe have confirmed this.

Hawking believes that a large extra dimension means that we live in an embryonic world, a four-dimensional' surface' or' membrane' of high-dimensional space-time. Strong force, weak force and electromagnetic force will all be trapped in this embryo, so any physical problem that has nothing to do with gravity will be the same as 4-D space-time. Gravity will spread to the whole high-dimensional space. In other words, gravity may decrease with distance faster than previously estimated.

So the orbit of the planet will be unstable: the planet will either fall into the sun or escape from the sun into space. However, this effect will not happen if the extra dimension ends in another embryo not far from the embryo on which human beings depend. Then, for the distance beyond the separation of two embryos, gravity cannot spread freely like the electromagnetic force mentioned above, but is effectively confined within the embryo, and the decline rate is just suitable for the planetary orbit.

Hawking mentioned in The Origin and Destination of the Universe that the Milky Way is a rod-spinning galaxy. Stars rotate slowly around the center of the Milky Way for about 200 million years. If Kepler's law is applied, the speed of the peripheral stars should be slower than that near the center of the galaxy, but the observation results are different, and the speed of the stars in the whole galaxy is roughly the same. Therefore, astronomers believe that there are a lot of dark matter in the Milky Way, most of which are distributed outside the Milky Way, thus accelerating the movement of stars in this part of the region. The research on the motion of all galaxies in the cluster of galaxies has also reached the same conclusion.

Hawking believes that in the four-dimensional "membrane" world, human beings live in an embryo and there is another "shadow" embryo nearby. Because light is confined in one embryo and cannot spread to another, human beings can't see the shadow world. But humans will feel the gravitational influence of the matter in the shadow embryo. This kind of gravity will appear as a "dark" source in the embryonic world of human life. The only way to detect "shadow" embryos is through gravity.

Hawking said that strings, membranes and embryos "have quantum fluctuations like anything else in the universe." "These quantum fluctuations make objects such as embryos spontaneously produce and disappear. This process is a bit like the formation of steam bubbles in boiling water. Heisenberg uncertainty principle in quantum mechanics leads to the birth of embryos from bubbles. If this four-dimensional bubble continues to grow, then people living on this bubble will feel that the universe is expanding.

According to Hawking's unbounded hypothesis (Hawking mentioned in "The Origin and Destination of the Universe" that the universe is finite and unbounded, just like the surface of the earth, only with two more dimensions, and the only condition for the boundary of the universe is that there is no boundary), the spontaneous creation of the embryonic world has a history of wasting time. In this history, the universe is like a shell: a four-dimensional sphere. Only the shell is empty, and the 4-dimensional shell in this embryo world image is full: the history of human life in virtual time is a 4-dimensional ball, which is the boundary of a 5-dimensional bubble, while the remaining 5 or 6 dimensions curl and roll very little.

According to Hawking's theory, the history of an embryo in virtual time will determine its development in real time. High-dimensional bubbles have the highest probability of producing a completely smooth spherical 4-dimensional "shell" in virtual time; However, this corresponds to an embryo that expands forever in real time. Galaxies cannot be formed in this embryonic world, so intelligent life will not appear. However, although the probability of high-dimensional bubbles producing a slightly unsmooth and aspheric four-dimensional "shell" in virtual time is slightly lower, it can correspond to the process of deceleration and expansion in real time (the embryo has an accelerated expansion-expansion stage at the beginning, and then the expansion slows down). In this process of deceleration and expansion, galaxies may form and intelligent life may appear. Interestingly, these intelligent creatures will create a theory of the universe and realize that they are from a four-dimensional "movie" that is not so smooth and not so round.

After reading "The Universe in the Shell" and "The Origin and Destination of the Universe", I have a feeling. Humans are too small, put in the vast universe, only stay in the theoretical stage, and have no strength to practice at all. And some human beings who want to challenge nature and the universe are too arrogant and ridiculous? Although they can say that human ontology determines the universe, people all over the world are unconvinced without conclusive evidence. Creationism is even more impossible. Do they want to talk about their almighty god? Unfortunately, dear God is not omnipotent. Can he make a stone that he can't lift?

There are many unknown worlds waiting for us to explore. I believe there is only one fact. In the future, mankind will definitely get the answers we want.

Reflection on the Universe 6 Our universe is actually a movie. All the objects are moving in the movie, and the surface of the movie is only the time to travel through everything.

In the general theory of relativity, massive objects will bend space-time to varying degrees, which shows that the self-weight of the object bends the surface of the film. As we all know, the propagation path of any object is the shortest straight line, and when time passes through a curved film, the path it takes is bent by mass, so a massive object will bend space-time, which is not allowed by special relativity.

At first, there were many (or infinite) membranes (universes) in nothingness. Because nothingness is not space, it is infinite. Fortunately, our membrane began to expand in some way, so everything appeared. However, infinite space represents infinite probability, so there must be another film expanding, and they will meet sooner or later!

This is a phenomenon that cannot be explained by our current laws. It seems that there must be more advanced laws of physics waiting for mankind to discover. When the current theory can't explain some phenomena, it's really impossible to claim to have found the theory of everything, such as the film itself-time.

Time is a puzzling mystery, many scientists hate it, but it is their responsibility, but they choose the ironic method-escape. At present, our membrane still has some unsolved mysteries, waiting for people to understand it. This is the novel world of film, the foundation of all things.

After reading the book Mysteries of the Universe, I feel that there are 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 ...

Reflection on the Universe 8 Are we unique in the vast universe and the Milky Way? Is the sun expanding or contracting? Where is the ultimate destination of the universe? After watching The Mysterious Universe, I was lost in thought. I can't answer these questions, and scientists can't give answers.

This is not surprising, because we humans are still in infancy, and we are still ignorant children. Although we have experienced a long history of 3 million years from apes to the ground, it is too short compared with the history of 4.6 billion years on earth and 20 billion years in the universe!

We invented an aircraft with a speed of 500,000 kilometers per hour, but at this speed, we can't escape from the black hole at all, let alone explore the vast universe. We have found many asteroids, black holes and nebulae, but there are more unknown asteroids, black holes and nebulae in the universe. The universe is so big! (after reading)

The earth is the cradle of mankind, but we can't stay in the cradle all the time. This cradle, like everything else in the world, has a beginning and an end. This correction is getting closer and closer to us step by step. One day we must leave the earth to open up a new home. However, can we do it by relying on our existing science and technology?

After reading the mysterious universe, I put away my usual arrogance and saw my ignorance clearly. I believe that under the mirror of the universe, we will make up for our own shortcomings and start a greater exploration.
