Superstring Theory

Emmmmm... I originally came here after looking at the bookshelf of 39, but I don't know why, the more I looked at it, the more addicted I became [thinking]

The content of this book is very interesting. Although it contains a lot of obscure physics terms, you can look it up and you will definitely improve. The most important thing is that this is the field that Sister Zhiwei specializes in [shy]

I came to see it from the drama god, so I couldn't understand it, but it was still very interesting!

Came here for Sanjiu... I am currently in the second grade of junior high school, and I don't have much knowledge. I only understand half of it [face covering]

Isn't this just a cool article [face covering] New geniuses are constantly overthrowing the old foundation of physics, and they are constantly instilling some lofty terms in you to improve your skills, and finally give you some scientific shock [Thinking] It's more exciting than TM's cool article

It seems to say something, but it seems like it doesn't say anything. In fact, the book can be summarized in one sentence. The universe is composed of superstrings, and the different frequencies of the vibrating strings manifest themselves as different forms of matter (personal understanding). The rest are to introduce the development situation and look forward to the future.

It's one thing not to understand, but it's another thing to like to read

It is a difficult book to understand. This book is very theoretical and requires a wealth of physics knowledge to understand. This is a relatively new theory in the world of physics and can be used to explain many physical problems. The author is a physicist and one of the founders of superstring theory, a theory that resolves a once dichotomy in physics and may make the Theory of Everything a reality. Although I didn't quite understand it, I still read it with great concentration. Understanding areas that I'm not familiar with can broaden my horizons.

MD is good NB, I came here for the drama god.

Can I be the King of the Red Dust after reading this?

Superstring theory is a scientific theory that attempts to unify the four existing forces. Although this theory is still in the hypothetical stage, it is correct in terms of theoretical inference. After reading in depth, although I still don't know much about some theories, I can still understand the general idea. It is a pity that there is no Chinese figure in this theory. Therefore, I strongly recommend it to readers. Maybe there will be a great theoretical scientist from China who can influence the world in the future!

Erjiu is really attentive [crying]

After reading this, go and fight with Mr. Hongchen

I'm watching it carefully, but I just don't understand much [face covering]

Wow, so advanced, how can I understand it without even watching it? But it feels very interesting

Because the drama god came.

Too much professional knowledge, pure practical information, good-looking, but I can't understand [laughing and crying]

Superstring theory The tortuous development of unified field theory from its inception to today's superstring theory is in some ways akin to a mystery novel. -The book is like a mystery novel, the story progresses in stages. -The first stage, the introduction of the main characters. This corresponds to the era of Newton, Maxwell, Planck, and Heisenberg, when the fundamental nature of natural forces was determined and clarified. However, physics took too long during this period, lasting several hundred years, because the direction of research was unclear. Compared to murder mysteries, the crime is clearly defined. In physics, only Einstein, who worked in complete isolation in the 1930s, had a clear idea of ​​the direction physics should take. In addition, he lacked key information about one major player: nuclear power. -In the second stage, patterns emerge linking different individuals, giving us our first clues to the identity of the criminal. In physics, this corresponds to the puzzling but steady progress made in the 1950s and 1960s, when physicists recognized SU(3) in the strong interaction and SU(2) in the weak interaction. Lie groups are considered to be an appropriate form to explain various forces, but scientists are not clear about their origin and purpose. The quark model is not fully understood and it is not known what holds quarks together. - In the third stage, a relevant and explicit theory is developed linking a person to the crime. In physics, this corresponds to the 1970s, when gauge symmetry was clearly recognized as the framework for the unification of the strong, weak, and electromagnetic forces. However, this is also a false start. S-matrix theory was proposed as an alternative quantum field theory, but it eventually helped give rise to string theory. However, the significance of string theory was dismissed during this period. -In the fourth stage, the clues are in place and the final conclusion is made. In physics, this corresponds to the fact that over the past few years, superstring theory has become a theory without rivals. Although the experimental situation is still up in the air, scientists have enough convincing theoretical results to believe that superstring theory is the unified field theory we have long sought.

I actually watched it for so long because of the God of Drama! Although I don't understand much

I just can't understand it. It feels very high-end, and many people have given it five-star reviews. My hand slipped accidentally. Just give it four stars.

Very good. It helps high school students broaden their horizons. Some unfinished content in the textbook has been updated and supplemented.

Compared with the popular science of string theory, the content of this book is more focused on the history of theoretical development. The book introduces many scientists, but it does not introduce the most cutting-edge theoretical research. I learned about an interesting concept called "One String Theory". The lovely thing about science is that you always admit your ignorance. Regarding the secret of the end of the universe, science will say that there are different theoretical models, but they are all theoretical conjectures that are difficult to prove; as for the basic particles that make up the world, science will say that we cannot observe the position and speed of particles at the same time, and currently we can only use probabilities to explain it.

Superstring theory is a theoretical framework in existing theoretical physics that aims to unify quantum mechanics and gravity theory. It believes that all matter is composed of tiny, vibrating strings, rather than point particles in traditional particle theory. If you want to know more about superstring theory, you can read this book. The book introduces many characteristics of superstring theory, which can help you sort out the main content and scope of application of superstring theory as soon as possible.

I can't understand this book with my current knowledge, but it would be much better if I could read it.

It is more like a book explaining the history of the development of quantum mechanics. Very little explanation of theory

Physicists have established a supersymmetric theory of N=8 to unify fermions and bosons. This means that in addition to the four dimensions of the universe, there are also four dimensions. This eight-dimensional universe is called superspace. However, this additional four dimensions cannot be understood as time or space. During the time, the eight-dimensional universe is inhabited by fermions. Matter can transfer from the four-dimensional space to the eight-dimensional space where fermions live through spin, and can also transfer from the eight-dimensional space back to the four-dimensional space. That is, bosons can be converted into fermions, and fermions can be converted into bosons. There is no difference between them.

When it comes to Professor Michio Kaku, what impressed me most is that he used ponds, carp and lotus to make analogies to the human world.

String theory in the womb [laughter]

The road to unifying the four fundamental forces is destined to be difficult. Countless scientists have devoted their entire lives to this goal to perfect the theory step by step. Superstring theory is another attempt on this road. In the near future, we may be able to see the perfection of a unified field theory.
