Weakness is called unsustainability, weak interaction is called unsuspecting, october 1956, "challenges of unsustainability in weak interaction" -- a rocky paper that shocked the world's watanic spring thunder! In october 1957, the world-renowned nobel prize for physics was unveiled by two young chinese physicists, prof. Yang jin-ning, 35 years old, and prof. Lee jung-do, 31 years old, for the year they had just published... Astrophysics is one of the most advanced scientific frontiers of modern development. It has historically been the cradle of new ideas and ideas, and each of its new achievements will shock the traditional perception of humanity. As the indisputable authority of contemporary cosmology, widely honoured by the world as the greatest theoretical physicist after einstein, steven hawking, whose research and life has been fiercely contested by the world's people, seeking to lead “nano-technology”, also known as “microtechnologies” and “super-microtechnology”. One nanometer is only one billionths of one metre and only a dozenths of a medium-sized atom diameter, roughly one hundredth of one adolescent female hair. "super-microtech" is like the most modern state-of-the-art authors, such as "superconductive technology", "biogenomic technology", "controlled thermal nuclear technology": in october 1957, two young chinese physicists, prof. Yang jin-ning, 35-year-old, and prof. Lee jung-do, 31-year-old, were awarded the great scientific prize of the world's scientific community. The world's scientific community is shaking and the world's physics is cheering! The children of the world's yellow-skinned children are excavating, and the children of china are chorus: the scientific chinese will make a greater contribution to the scientific cause of humanity! At the dawn of this new century, let us revisit the great scientific journey of professors yang jin-ning and lee zheng do to achieve this remarkable achievement, in order to inspire our ambition, morale and courage in our quest to teach and modernize science and technology. First, the concept of symmetry and its scientific classification are very familiar with the symmetry of nature and life. The hexagonal snowflakes, the flying butterflies, the eiffel tower in paris and the old palace layouts in beijing all have symmetrical patterns. In the changing dynamics of nature, symmetry is evident in all its diversity. Symmetry is one of the general attributes of nature and symmetry is one of the principles that human life loves. In the evolution of nature, symmetry has continued to develop (damaged), while at the same time showing some new symmetry. Research symmetry is an important aspect of understanding natural patterns. The strict definition of symmetry is proposed by german mathematician hermann weyl: after a change in a thing, the thing recovers completely, saying that the thing is symmetrical of the change that it has undergone. And that's called symmetry. So-called transformation here is the process of a physical system (object) from one state to another. Scientificly, the description is classified according to the nature of the transformation and the object involved. The two most basic categories of symmetry are spatial symmetry and temporal symmetry. Space symmetry has spatial symmetry such as spatial symmetry and space rotation; time symmetry is most important in time symmetry. The three are symmetry of continuous variations and symmetry of discrete variations. The common dichotomy symmetry is time inverse symmetry, space inverse symmetry and charge symmetry. In physics, symmetry is also referred to as internal symmetry as reflected in variations of other nature independent of time and space. As the microworld is increasingly explored, its internal symmetry is being found. Like a bit, odd, light, heavy. The symmetry of the laws of physics is reflected in the symmetry of nature as a law of physics. It refers to the characteristic (also known as no change) that the form of the laws of physics remains unchanged after some change. For example, time-altering is a free fall experiment on the pisa tower 400 years ago, as it is today. This is what people say: “scientific truth is eternal”. For example, spatial homogeneity refers to a free fall experiment on the pisa slope tower, as well as on the sioux hill tower. This is called “true is universal”. In the case of space rotation, constantity refers to the transfer of the whole set of experimental instruments (with external factors affecting the experiment) to any angle after an experiment has been carried out in a place in space, which will be carried out in exactly the same manner under the same starting conditions. It is also called the law of physics, or the same orientation of space. Inverted integerity of time is when the physical equation is converted to -t, and the physical pattern is the same. (conservative motion patterns are time-inverted. Time is replayed, as the video is replayed: clapping hands, single-showing looks the same as playing). The constantity of the charge means that the physical pattern remains unchanged after all particles in a physical process have a reverse charge number (e→-e). The german scientist a. E. Noether, in 1918, established a theorem (known as the non-specific principle): for every symmetrical physical law, there is a constant law. The third symmetry of the above time-sizing, space-spacing and space-rotation corresponds, respectively, to the third constant law of constant energy, constant momentum and constant agular motion. Time inversion and charge symmetry correspond to t and c, respectively. It was first generally proven in classical physics, and it was subsequently extended to quantum mechanics. Iii. It's called "resistence", and the mirror is a daily living item. The image of the left hand in the plane mirror is the right hand, a common knowledge known to three-year-old children, and it happens to be the simple common sense that connects to a deep scientific principle: there is an important symmetry between the mirror and the original -- mirror symmetry (also known as left-right symmetry). In a slightly academic language, it is called mirror symmetry if there are two parts, part of which is another part of the mirror. According to vail's definition of symmetry, mirror symmetry can be expressed as having an x-axis vertically on the mirror, with the original point on the mirror, and turning one half of the graphic x into a-x and getting the other half. This x-coordinate variant is called mirror symmetry. It is this mirror symmetrical development that has become the concept of parity in the microworld. We know that classic physics does not use the concept of a name, but the laws of physics always show complete symmetry between the right and the left. This symmetry, in quantum mechanics, forms a constant law known as parity conservation. It's exactly the same symmetry as left and right. The concept of the name was first formed by e. P. Wigner. It is useful in the atomic spectra, and then used in atomic nuclear physics and particle physics, both indicating the success of the concept and the principle of constantity. If we transpose mirror mirrors to x, and extend them to y and z, that is, to change the symbols of all coordinates (x-x, y-y, z-z), it is called space inverse evolution. After this change, if the physical pattern is the same, it is called space inversion. The constant amount associated with space inversion is the name. The constant law of inversion in space is called the constant law. It now needs to be clear what the word is. There are various accounts of the principle of stability. A more understandable formulation is: “any process that occurs in nature, if we look at it in the mirror, can happen in nature as well. So nature is a mirror. The mirror of any object is also an object that may exist in nature. The movement of any object seen in the mirror is also permitted by the laws of nature. Any experiment done in the laboratory can also be done in the form of the original experiment in the mirror and the result will be a mirror of the original results”. In short: “the laws of nature remain the same under mirror reflection”. There are only two scenarios between a system and its mirror: (a) it's exactly the same, it can overlap, it's called an even, it's a +1. (b) unable to fully overlap and to the left, referred to as ziu and ziu. In basic particles, there are “inner talent” (p=+1 or 1) and “orbit” (π(-1)). For a particle system in nuclear physics, it is referred to as the total product of each particle description, and it is found that various movements in nature have spatial inversion symmetry and that the pre- and post-reaction systems of the basic particle are unchanged. As a result, it has long been recognized as the norm。as the space invert value is equal to: (scopy reflection x→-x)+ (turning 180 degrees y→-y, z→-z) and because the rotational symmetry is established, the mirror reflection symmetry test is equivalent to the space inverse symmetry test, i. E., the constant test of the proximate. In short, reflecting real experiments with a plane mirror can test the persistence of the term. Fourth, the constant dilemma is that there are now four interactions in nature: gravitational interaction, electromagnetic interaction, strong interaction and weak interaction. Reference
