Yang Zhenning won the Nobel Prize in Physics for the non-conservation of cosmology under weak interaction, and the non-conservation effect of cosmology had a major impact on physics, and won the Nobel Prize that year. This rate of awarding is unprecedented in the history of more than 100 Years of Nobel Prizes, which is enough to see the significance of this achievement.
The first point of knowledge, the law of non-conservation of cosmology, refers to the asymmetry of motion of matter mirrored by each other in weak interactions. This is a big discovery, and the entire scientific community of mankind, until 1956, had always considered the conservation of cosmology, and it was unanimous that the mirror image of a particle was exactly the same as its own nature. The emergence of Yang Zhenning has directly reworked this scientific law, and scientists around the world are dumbfounded and suddenly realized.
We can illustrate the problem with a similar example. Suppose there are two cars mirroring each other, with the driver of car A sitting in the left front seat with the accelerator pedal near his right foot, while the driver of car B sits in the right front seat with the accelerator pedal near his left foot. The driver of Car A starts the ignition key clockwise, starts the car, and presses the accelerator pedal with his right foot to make the car move forward at a certain speed; the driver of Car B also does exactly the same action, just swapping left and right - he starts the ignition key counterclockwise, presses the accelerator pedal with his left foot, and makes the pedal tilt consistent with A. How will Car B move?
Perhaps most people would think that two cars should be moving forward at exactly the same speed. Unfortunately, they made the mistake of taking it for granted. Experiments with the non-conservation of cosmic names prove that in the particle world, Car B will travel at completely different speeds, and the direction may not be the same! - The particle world is such an incredible demonstration of the non-conservation of cosmology.
This is a bit like the double-slit interference experiment in quantum mechanics, although the essence is different, but ordinary people understand it is a lot more convenient, if even the double-slit interference experiment does not know what it is, then I will say a more appropriate analogy, it is like, your child is writing homework in the bedroom, when you want to push open the door to see if your child is seriously reading, you see that your child is writing homework, of course, when you go back to the living room to play mobile phone, your child may have put down the pen and brought 4 pit cargo teammates to fight a group battle.
Particle observation is also so magical, and it is too time-consuming to explain in more depth, and I believe that many adults have a hard time getting out of the classroom and must not want to listen to the long scientific operations. Therefore, the discovery of the particle world has always changed mankind's understanding of the world and even the rules of the universe. And Yan Zhenning's first card is the weak interaction, the mutual mirror of the movement of matter is completely asymmetrical cosmological non-conservation law of this big discovery, directly changed the century of science truck to another track, the key is that the scientific community can not deny, because it is already a proven cosmic big fact!
however! The non-conservation of cosmology under weak interaction is not Yang Zhenning's greatest scientific contribution, and Yang Zhenning is great because of his Yang-Mills equation. The Young-Mills theory is even more distant for most people, and to introduce it needs to rise to the level of being able to see almost the entire physics. By analogy, if I were to popularize black holes, I would only need a few concepts of physics. And most people can have a certain understanding and concept of black holes.
Describes the theory of vector particles with self-interaction.
Vector particles are the excitation of vector fields, for example, electromagnetic fields are vector fields, and its excitations — photons — are vector particles. But Maxwell's equation, which describes the electromagnetic field, is linear, meaning that there is no interaction between photons (ignoring the quantum effects produced by charged particles), and its manifestation is that the photons themselves are not charged.
Some vector particles themselves also have corresponding "loads", so they will interact with themselves. At this point, the linear Maxwell equation cannot be described, and we need a nonlinear equation to describe, that is, Young Mills' theory.
This is Yang Zhenning's second card, I think now you may have a little bit of a little unconscious rush to the yang Zhenning god, yes, overthrow! reconstruction! Let all mankind follow, and this road is correct, when the only cosmic truth is solved, Yang Zhenning's name began to be worshipped with Einstein and Newton, and even in order to discuss who is more cattle, many people talked for a long time, and even stayed up all night.
To say that Yang Zhenning is great, we must first understand why Newton, Maxwell, and Einstein are great. Newton was the epitome of physics of his time, and the motion of objects in the sky and on earth can be described in several simple and beautiful formulas given by Newton. Physics is all about encompassing a wider range of phenomena with as few formulas as possible, and Newton unified the forces of heaven and earth, the first great unification in the history of physics.
After Newton, the intricate chaos of electricity, magnetism, and light was sorted out by Maxwell with four equations, and Maxwell unified electricity, magnetism, and light.
Maxwell's equations are great, but this equation is not co-variable under the Galileo transformation, and the speed of light derived from Maxwell's equations cannot be seen relative to which reference frame. Einstein came out to solve this problem, that is, Einstein's special theory of relativity.
Special relativity gives the scope of application of Newtonian mechanics and establishes the correctness of Maxwell's equations. But there is one more headache that has not been solved, and that is the problem of gravity. Einstein spent another decade giving the general theory of relativity, and the problem of gravitation came to an end.
After the gravitational problem was solved, Einstein did not stop, because he saw a new big problem in front of physics, that is, the unity of gravitational and electromagnetic interaction forces. In his later years, Einstein devoted a great deal of energy to unifying gravitational and electromagnetic interactions, but he did not succeed. Moreover, two other interactions were found inside the nucleus— weak interactions and strong interactions, and at the time, scientists didn't even know how to describe strong and weak interactions.
At this time, Yang Zhenning used his theory to guide the direction. In 1954, Yang Zhenning published his Yang-Mills gauge field theory, which did not directly give how to describe interactions, and several very outstanding scientists such as Gell-Mann and Weinberg used this theory as a framework to give quantum chromodynamics describing strong interactions and weak-electric unified theory (the unity of weak interactions and electromagnetic interactions). At this point, it can be seen that the electromagnetic interaction, weak interaction and strong interaction of the four interactions are all completed under the framework of Yang Zhenning's gauge field theory.
Therefore, it is no exaggeration to say that Yang Zhenning is the pride of all mankind. For example, many netizens will ask what is the difference between humans and animals? The next time anyone asks you, I'll teach you, and you'll just say to someone, "Humans have the Love and Young-Mills equations, do animals have them?"
As soon as you say this, you can definitely make your body rise to the shore, because this sentence is like standing on the shoulders of giants, so the deep meaning behind it is the difference pointed out by the answer to the question.
In one word, "cool"!
In addition, Yang Zhenning's cards can be more than two, but as a junior, I am introducing Yang Zhenning to everyone, understanding Yang Zhenning, Yang Zhenning more Wang Fang, I am not worthy of a long speech.
Let us worship Mr. Yan Zhenning, happy 100th birthday! Please allow the younger generations to offer a heart!
