It is said that Yang Zhenning is the top scientist in the world. How good is he?

Yang Zhenning is the greatest scientist after World War II. You may be surprised, but it is! Scientists have always kept a distance from the general public. If we keep an ignorant attitude towards science and stay away from others, it doesn't actually affect our down-to-earth life, but if you know their "heroic deeds", your attitude towards them may turn 180 degrees!

Yang Zhenning, in particular, because all the news about Yang Zhenning that comes into everyone's sight has private opinions, how to understand Yang Zhenning's achievements from a positive attitude is actually very simple. Just list his academic achievements!

The law of parity conservation, which won the Nobel Prize, ranks only third in his academic achievements.

Parity non-conservation refers to asymmetry in weak force. Earlier, the scientific community's belief in symmetry was unshakable, and Nott's law proved that this symmetry was as reliable as the conservation of energy from the mathematical level. Therefore, when Yang Zhenning and Li Zhengdao discovered the phenomenon of weak force non-conservation in 1956, the scientific community generally held a distrust attitude towards the research of these two young people, and it was not until Wu Jianxiong verified the law of parity non-conservation with the decay of cobalt 60 nucleus that it exploded in the scientific community!

From 1956, when Yang and Li discovered that parity was not conserved, to 10/957, when they won the Nobel Prize, it was only a short period of 12 months, which was unique in the history of the Nobel Prize, which also confirmed the significance of this discovery to the scientific community from another side! Among all symmetries, only a little asymmetry of weak force creates the universe, which is almost uniform in microwave background radiation, but it is this one millionth asymmetry that creates the birth of stars and galaxies, which is of great significance!

After talking about parity non-conservation, let's continue to talk about Young Mills equation and Young Barkis equation, because among the achievements, Young Mills equation, followed by Young Barkis equation, and then the law of parity non-conservation. What about these two equations? Why didn't greater achievements win the Nobel Prize?

Young-Mills equation and Young-Backus equation.

At the earliest, Yang Zhenning had the direction of standardizing field theory in Taylor's doctoral thesis. He abandoned the direction of Taylor's thesis and chose four goals:

Ising model

Bette hypothesis

gauge field

Angular distribution in nuclear reaction

Three of the four directions are stuck. Yang Zhenning graduated from Taylor's school with his last article "Angular Distribution in Nuclear Reactions". Although Yang Zhenning graduated, the direction he set in his graduation thesis did not end. One year after graduation, Yang Zhenning and Li Zhengdao completed the expansion of two-dimensional Ising model to three-dimensional, which triggered academic research. Finally, Onsager, who has the deepest skills, won the Nobel Prize!

Gauge field is Young Mills theory, which is based on SU(N) group. 1954 and robert mills founded Young mills' theory, which extended the gauge theory of commutative groups to non-commutative groups to explain the strong interaction, but it was questioned by Pauli, because in Young Mills' theory, the quantum must have zero mass to maintain the gauge invariance, and no particles with zero mass were found at that time. Young Mills' theory can't explain the quality problem of B quantum dots, so the paper has not been paid attention to, and even I don't know the purpose of this theory!

In 1960s, the scientific community began to use symmetry breaking mechanism, and Young Mills theory became an important tool to explain particles with zero mass, but the importance of Young Mills theory has just begun!

In 1967, Weinberg and glashow introduced the spontaneous breaking of gauge symmetry, established the unified theory of electric weakness on Young-Mills field theory, introduced Higgs mechanism, and put forward the electric weakness theory of U( 1) ×SU(2) gauge symmetry.

1972, freese and gherman put forward Young-Mills theory with SU(3) gauge symmetry, and established quantum chromodynamics.

Up to now, the standard model of particle physics has two pillars: the weak theory of electromagnetic force and weak force and the establishment of quantum chromodynamics to describe strong force. Simply put, the theory of Young Mills is the basis of the standard model of modern particle physics!

Bethe hypothesis, later known as Young-Baxter equation, originated from a statistical mechanics problem. In order to exchange the R matrix associated with tetravalent vertices and the row-to-row transfer matrix of lattice, Yang Zhenning solved the one-dimensional quantum N-body problem and anisotropic Heisenberg spin chain with D- function interaction by Bethe Ansatz method in 1960s, and proposed the Yang-Baxter relation.

Since the study of Jan Mills theory and Jan Bacchus equation, there have been seven Nobel Prize winners successively, and six others have won Fields Prize (Nobel Prize in Mathematics) for their study of Jan Mills theory and Jan Bacchus equation.

1994, when Yang Zhenning was awarded the Bauer Prize, the acceptance speech was still a bit disgusting. "This work has been arranged in the works of Newton, Maxwell and Einstein, and will have a similar impact on future generations." However, this evaluation is not exaggerated, because Yang Zhenning, like Newton and Einstein, will have a huge and far-reaching impact!

Yang Zhenning's academic achievements go far beyond this. These are just his most famous achievements as a case to illustrate Yang Zhenning's position in the scientific community. Of course, it doesn't matter if you don't understand. This has nothing to do with our daily life, but once we understand it, it will obviously have a great impact on our world view, and you will realize a completely different scientific world!
