I. Introduction to the author
Kakumichio, a Japanese-American physicist, graduated from Harvard University in the United States with a doctorate in philosophy from the University of California, Berkeley, and later served as a professor of theoretical physics at the City College of the City University of new york. His major works include Beyond Einstein (co-authored with Trina), Quantum Field Theory and Introduction to Superstrings.
Second, related knowledge
In order to better understand the text, we need to know some related theoretical physics knowledge:
(1) unified field theory
According to the knowledge of modern physics, there are four forces that unite our universe: gravity, electromagnetic force, strong nuclear force and weak nuclear force. Physicists use quantum mechanics to unify the latter three forces (Chinese-American physicist Yang Zhenning and his student Mills put forward Yang Yi Mills' field theory, which solved this problem and was called the "standard model". But this theory is a headache, because the calculation is complicated, but gravity is still free. Einstein tried hard to seek the unity of the four forces and establish a unified theory all his life, but it never came true.
(2) High dimensional space
Modern theoretical physics believes that the prospect of unifying the four forces lies in the establishment of the theory of high-dimensional space (such as ten or higher dimensions). For example, for the ancients, they knew nothing about how the storm came into being, where it would strike, when it would strike and when it would end, because they lived on a flat land and could only observe it with the naked eye from a similar two-dimensional plane. Even with simple predictions, they rely on experience to speculate. Now with meteorological satellites, we can observe the earth from a three-dimensional perspective like space. On the ground, you can clearly see the mysterious storm and accurately predict the trend of the storm. Similarly, theoretical physicists believe that the traditional four-dimensional (three-dimensional space plus time) theory is too small to explain the four forces in the universe. When they transcend four dimensions and seek to unify these four forces in higher dimensions (such as ten or higher dimensions), they can get a simple and beautiful solution model (scientists believe that the universe should be simple and harmonious).
According to the theory of high-dimensional space, after BIGBANG 10-43 seconds, the ten-dimensional universe was decomposed into four-dimensional and six-dimensional universes, and the four-dimensional universe exploded, and after nearly15 billion years, it evolved into the universe we live in today. 10- 35 seconds after the big bang, unification was separated by a force. However, the theory of high-dimensional space is difficult to be confirmed in the laboratory, because it takes too much energy to simulate the environment at that time, so the theory of high-dimensional space can only be "theory" now.

2. The basic content of this paper.
Cooperative investigation
1. The three main parts of this paper are not simply telling the story of growth, but have profound scientific spirit connotation. What aspects of "education" can be regarded as the most important factor to become an excellent scientist?
The questioner said, "I have decided to get to the bottom of this problem, even if I have to become a theoretical physicist." What kind of person should the "theoretical physicist" in the author's mind be?
What's the significance of asking the author to set up a laboratory for our real life?
