After tasting a famous book, I believe everyone has accumulated their own reading experience. Why not calm down and write about your feelings after reading it? So do you really know how to write a review? The following are 500 words carefully arranged after I read the physics extracurricular book. Welcome to reading. I hope you will like it.
500 words after reading a physics extra-curricular book 1 Once the father of a young American reader said: After reading this book, he is no longer afraid of death. ...
This is the highest evaluation of a work. After reading the book, I think this evaluation is not excessive. Death is the greatest fear in the depths of human life. In order to avoid the inevitable fate of death, we can do all kinds of incredible things. Of course, this fear can also lead us to create and invent. We can't fight against eternal time (the author of A Brief History of Everything doesn't seem to agree that time is eternal! ), but we can choose how to describe time, which is one of the more rational outlook on life. "A Brief History of Everything" can make mankind understand that he is so arrogant, without capital and necessity. He should treat life outside and life itself rationally and peacefully with a grateful heart. The above is what this book can bring to adults. For children, perhaps this book will edify the Nobel Prize winners many years later, because it shows that science is also interesting and wonderful, and not as boring as we thought. So I've always wanted to recommend this book to everyone. The original plan was 10. 1 Write a book review. But I was in a bad mood and didn't write. Now when I am in a good mood, I forget many details and don't know where to start. I'm going to read it again, take notes and then write it. I opened the introduction and found that it was actually a very good temptation. I decided to buy it, and the introduction played a big role. Of course, there is a preface written by Xu Zhihong, president of Peking University. Without going into details, let's take a look at the introduction of a brief history of everything.
The responsibility of seeds is to blossom and bear fruit, the responsibility of gardeners is to take care of gardens, the responsibility of doctors is to heal the wounded and rescue the dying, and the responsibility of teachers is to preach, teach and dispel doubts. As students, our responsibility is to study hard, make progress and be an excellent student.
Recently, I read another book called "The Softest Physics Book in the World".
From this book, I learned a lot of knowledge that I didn't know before, such as why a roller coaster can run so fast without an engine? Why is it difficult for us to stop while skating? What makes the stars shine? There are many questions, and I can find the answers in the book. I asked my mother why others would know. So much, but I don't know? Mom said that's because these answers were obtained by these scientists through countless studies and experiments.
Now I understand that we often encounter such problems in our daily life. If we can use our brains and hands, maybe we can discover the mystery ourselves. Mom said that there is science everywhere in life, so we should learn to find problems and actively use our brains and hands to solve them. This can not only cultivate our innovative spirit and practical ability, but also improve our scientific and cultural literacy.
Now I'm just a young eagle learning to fly under the blue sky. If I want to grow into a mighty, chic and free-flying eagle, I have to keep trying, be diligent in exploration and face difficulties. The road to learning is a road full of thorns. Only by mastering skills and having enough perseverance and determination can we succeed.
Therefore, from now on, I should learn to think more, ask more questions and use my head more, so that I can learn more knowledge and science. Students, let's work together!
Russell believes that philosophy is something between theology and science. Since human beings left the animal kingdom, they have been exploring the mysteries of nature and human beings in these three ways. In science, physics is the most basic subject and has the deepest origin with philosophy. It studies the material structure and the most basic laws of material movement in nature. Solid state physics is an important branch of physics, which studies the macroscopic properties and microscopic processes of solid materials.
Solid materials can be divided into crystal, amorphous and quasi-crystal in between.
Among the minerals in nature, crystalline substances account for more than 98%. The arrangement of atoms in an ideal crystal is very regular, mainly because the arrangement of atoms is periodic (or called long-range order), and the specific form of this arrangement is also called lattice. According to macroscopic symmetry, the rich crystal types in the world belong to fourteen crystal lattices. But the substance is not perfect, and there are always various defects in the actual crystal, which affect the properties of the crystal.
Lattice point is the equilibrium position of atoms in crystals, and atoms vibrate slightly near lattice point due to their thermal properties. The study of lattice vibration plays an important role in the study of macroscopic properties and microscopic processes of solid materials, but there is a strong interaction between a large number of particles in solid, which makes lattice vibration a complex multi-body problem, and it is difficult to solve the motion state of devices strictly. The introduction of phonon, an energetic but massless quasi-particle, simplifies the description of lattice vibration: phonon number can be used to describe the quantum state of normal vibration motion; The change of phonon number can be used to describe the transition between normal vibration quantum States; The anharmonic interaction can be described by the collision between phonons.
There is no long-range order in the arrangement of amorphous atoms, but there is a certain law, which is called short-range order. Quasicrystal is a new field of solid research.
As a liberal arts student, mathematics and physics are nightmares, and all information about them is automatically blocked when they are not in contact. Coincidentally, when I saw this book this time, I didn't have the pressure of annoying physical formulas and test scores, but I read it at once with the mentality of flipping through it.
Moreover, the history of physics is connected at once, and classical mechanics, blood, quantum mechanics, electromagnetism and relativity can all say several knowledge points close to life. For example, are there really ghosts in the world? To what extent has modern science studied quantum transmission? Can humans really realize human quantum transmission? What is gravitational wave?
Also, those anecdotes about the life of physicists have refreshed me. It turns out that Tycho had a false nose and Newton had a hard year. Bosons and fermions come from the names of physicists.
After so many years of graduation, the door of the physical world is open to me.
If I saw this book at school, wouldn't I be so afraid of physics and other scientific knowledge? Some things just drift away from them after their preconceptions.
More interestingly, focusing on one thing will lead to similar things. After reading this book, I began to read Three-body. I didn't expect that all the physical knowledge points in "Three-body" were what I knew or read. In this way, the original boring physical knowledge outside the story became the driving force that attracted me to continue reading Three-body.
This book is readable by everyone and everyone should read it. Physical knowledge is not in the examination paper, it exists in all aspects of our lives. With this knowledge, I really broadened my horizons and ideas.
