Relativity

The whole ten points is not too much, right? I never imagined that this could reach 8.6.

I am a freshman in high school. I read Hawking's "A Brief History of Time" and then read this book. Combined with popular science videos on the Internet, I can roughly understand it. I really admire the great man's wisdom and groundbreaking thinking and reasoning. By the way, I express my appreciation for physics.

I don't know if it's because of the translation's embarrassment. Or the original author was too rigorous for the sake of the rigor of the article, and there were too many details so that the main body was not prominent. Maybe it's similar to the rigidity of the times in classical Chinese translation, or maybe it's It's time to skip the minutiae... No matter what, it is undeniable that this book has led the progress of people for hundreds of years. Mr. Einstein is my idol from my childhood and even today. Although I am not star-chasing, my current life and education have really hindered my relationship with him. I also hate myself for missing the opportunity, so that my efforts are useless. At this point, I have truly realized that I am ordinary and cannot promote the scientific progress of all mankind like Einstein, but this is the reason why every one of us on earth works hard to live, isn't it?

I read "The Theory of Relativity" in the second grade of junior high school out of pure curiosity.

A breath of fresh air among tomatoes

I read it from beginning to end, forgetting it as I read it [laughing crookedly], but I feel like I roughly understand the theoretical content.

What's going on? Why is this book's rating less than nine?

Einstein's general theory of relativity reflects his philosophical viewpoint of materialism (slightly idealistic). But materialism is also constantly developing. The theory only works on certain matter and material movement in a certain time and space. For regularity to take effect, conditions are needed.

I read the first chapter carefully and just skimmed through the second and third chapters. I will read it carefully next time. 10 Points!

In essence, all problems in physics involve the question of which view of space and time to adopt. In classical physics before the 20th century, people used Newton's absolute view of space and time. The proposal of the theory of relativity changed this view of space and time, which led to people having to rewrite the formulas of classical physics in accordance with the requirements of the theory of relativity, so that they have Lorentz covariance required by the theory of relativity instead of the previous Galilean covariance. The theory of relativity proposed by Einstein points out that when there are no other forces except gravity, all test objects with a sufficiently small mass (that is, the impact of their own mass on the gravitational field can be ignored) will move in the same way in the same gravitational field. In this case, it may be considered that gravity is not actually a "force", but a space-time effect, that is, the mass of an object (accurately, it should be a non-zero energy and momentum tensor) can produce a curvature of space and time. The gravitational force of the gravitational source on the test object is a geometric effect caused by this curvature of space and time.

The theory of relativity is not so profound that it is completely incomprehensible. It contains the derivation of formulas, involving many branches of mathematics, starting with linear algebra, then geometry, complex variable functions, advanced mathematics, topology, graph theory, etc. It not only has rich physical knowledge, but also involves extensive chemical knowledge. Of course it is relatively well known that the theory of relativity is the masterpiece of Einstein's "free creation of the mind" or "free invention of the intellect". A lot of irrelevant content has been added to the full text, such as photos of Einstein's parents and life photos. During the reading process, the illustrations are a bit abrupt, interrupting the coherence of the content, which is a bit confusing.

There are no words to describe this book, it is faith.

I can't understand it, but I've finished reading it

I'm a junior high school student😂😂

The amazing theory of relativity

This book is very interesting! It introduces the theory of relativity in a simple and easy-to-understand way, even people like me who have no foundation in physics can understand it. I especially like the part where Einstein used real-life examples to explain the theory of relativity, such as the impact of relativity on time and space, which opened my eyes! Moreover, the language of this book is also very vivid, as if Einstein is chatting with us, and it is not boring at all. Recommended!

I always thought that if two people are in the same space, then the passage of time is also the same. Time and space exist objectively. They exist independently and have no necessary connection. Just like we live on the same earth, everyone is doing different things every day, and there are 24 hours in a day. But after reading this book, I felt that everything in front of me was an illusion. Einstein deduced that everyone's time can be different, and space also has length. As long as you move fast enough, you can make time relatively slower and space shorter. As long as you can move close to the speed of light, your life span will be measured in thousands of years relative to people on the earth. This is the most incredible, difficult to understand, and greatest part of the special theory of relativity. The reason why the faster the speed is, the slower the time is. The reason is that the speed of light does not deform. This is the most important basis in the theory of relativity. No matter how fast you move, you see that the propagation speed of light remains unchanged. This is really hard to understand because it doesn't match what we feel in real life and we can't feel it. But after reading this book, it really completely subverted our concepts of time and space.

I will come back. I didn't understand a lot when I read it for the first time.

Thank you, Einstein. This book makes me feel like I'm meeting you in a distant time and space. You showed me a wonderful world with your ideas. Thank you even though you can't see it.

Why does the theory of relativity score 8.8, And why does it not even break through 9?

Einstein used simple examples to vividly describe the theory of relativity, which is not too difficult to understand.

Many people don't understand Einstein's theory of relativity. "The Theory of Relativity" is a very challenging theoretical book. The content in the book involves a lot of physical knowledge, which makes people feel very strenuous after reading it. But this book is also a good popular science book that allows us to better understand Einstein's views on the universe and his unique insights into time and space. Einstein's view is that space and time cannot necessarily be viewed as things that can exist independently from real objects in the physical world. It is not that material objects exist in space, but that these objects have spatial extension. "The Theory of Relativity" is not only a theoretical book, but also a literary work. This book has concise language, rich content, rigorous logic, and clear structure. It is a good popular science book. After reading this book, I felt Einstein's strong curiosity and exploration spirit, as well as his enthusiasm and persistence in science.

I would like to know who is the translator of this version?

Einstein is a world-famous scientist. This is a classic scientific work written by Einstein. This book introduces the basic principles and mathematical expressions of the theory of relativity and explores the interrelationship between time, space, and matter. "The Theory of Relativity" explains the important theories of modern physics in profound and precise theoretical language. For readers who are interested in physics and philosophy of science, this book is a must-read classic and is recommended reading.

Just read it a few times.

Einstein's works all hope to reveal the mathematical principles in Newton's natural philosophy [eating melon]

I want to introduce the complex variable function and give it a try

The help of the theory of relativity to modern science is self-evident. The author's retelling is also very good, but I dare to make some suggestions. The length is a bit short. Many concepts are not mentioned. It is normal that other small things are not written. But I hope the author can add the light cone so that more people can understand it and many people can better understand the theory of relativity.

The theory of relativity is good, but the book is not so good.
