Yang jin-ning and lee jung-do, two great physicists, were the first chinese scientists to receive the nobel prize in physics. They reveal an unprecedented physical phenomenon. This discovery, known as intransigence, has completely broken down the long-standing belief of physics in the symmetry of nature and laid a new theoretical foundation for the development of particle physics. However, behind this achievement are their constant questioning of the laws of nature and their daunting challenges to classical theory. Today, we will look at the mystery of symmetry and beta decay from the point of view of the underlying concepts and reveal how they lead us to an understanding of the unsustainable nature of the term. This is not only a review of scientific discoveries, but also a tribute to the spirit of science: a spirit of exploration that has the courage to question and constantly pursue the truth. Today, we will explore the mystery of symmetry and beta decay in a step-by-step way, from the concept of foundation to the way in which these fundamental concepts lead us to a deep understanding of the lack of persistence of the term. This is not only a review of scientific discoveries, but also a tribute to the spirit of science: a spirit of exploration that has the courage to question and constantly pursue the truth。
From classic physics to the mirrors of quantum world
Parity is a very important quantum number in physics to describe the symmetry of the system after reflection in space. In physics, symmetry can simply be understood as requiring the behaviour of the symmetrical system to be fully consistent with its original state if the coordinates of a physical system are reflected, as is seen in the mirror. For example, if you raise your right hand in front of a mirror, your mirror will raise the left hand, but the overall position is still symmetrical, and the concept of mirror symmetry is referred to in physics。

In classical physics, symmetry is widely applied in newton mechanics, electromagnetics and other laws of physics, giving nature a high sense of symmetry. Many of the kinetic patterns and interactions in classical physics, such as the newton three laws and the maxwell equation group, follow the principle of symmetry, which means that nature's behaviour is fully symmetrical in mirrors with its original state. This symmetry reflects the universality and consistency of nature and is a concise and elegant way for physicists to understand nature's laws。
However, when physics enters the quantum field, the situation becomes more complex. Within the framework of quantum mechanics, symmetry is described by the characteristics of wave functions. If the wave function of the system remains unchanged in space inversion, the system is called having an even name; if the wave function becomes negative after inversion, the system has a miracle name. In the quantum world, the behaviour of particles is often fraught with uncertainty and probabilities, and this micro-level complexity forces physicists to re-examine whether symmetry is common in all interactions。
In strong and electromagnetic interactions, symmetry seems to have been validated. However, with the in-depth study of the underlying particles and their interactions, physicists began to question the generality of this symmetry. In particular, when it comes to weak interactions, scientists have observed in experiments phenomena that cannot be explained by the traditional principle of continuity. This question has become an important starting point for physicists to explore deeper patterns in the microworld。
Mysterious processes in weak interactions
Beta decay is a radioactive decay process involving weak interactions, usually occurring during the transformation of a neutron into a proton in an atomic core. This process is accompanied by the release of an electron (known as beta particles) and an anti-neutron microbe. Beta decay is a typical phenomenon in the study of weak interactions, unique in that they are not only relatively weak, but have a very short scope and are limited to subatomic scales, but they can change the taste of particles (flavor), for example, by converting neutrons into protons, thereby altering the composition of the atomic nuclei。

Weak interactions are one of the four basic interactions of nature, and the other three are gravitational, electromagnetic and powerful interactions. The performance of weak interactions in beta decay makes them one of the key ways for scientists to study basic particle behaviour. In the initial understanding of beta decay, physicists generally agreed that the process should be based on the principle that if the entire decay process is mirrored, the decay process in the mirror should be fully consistent with the actual decay process and the direction of the electronic launch should be random and even. However, with the advances in experimental technology and the accumulation of data, scientists note that the direction of the electronic launch is not always random, but rather shows some bias。
In order to better understand this phenomenon, we can use an analogy. Imagine a spinning gyro, if the ball is launched randomly during its rotation, and if it is known as constant, the direction of the ball should be evenly distributed from any angle. However, if we find that the ball is always in favour of a particular direction, this means that the symmetry of the system has been destroyed. In β decay, the launch of electronics appears to have a certain bias rather than a balanced distribution as expected, a phenomenon that has become an important clue to physicists' doubts about the universality of the term。
This bias suggests that there may be mechanisms in weak interactions that were previously unknown, leading to the destruction of symmetry in such interactions. This discovery has made physicists aware that the notion of continuity may not be applicable to all interactions, especially where weak interactions are involved, and has prompted scientists to explore basic particle behaviour in greater depth。
S scientific revolution from beta decay
It is because of the results of experiments observed during beta decay that do not conform to the definition of persistence that yang jin-ning and lee zhengdo presented in 1956 a bold theoretical assumption: in weak interactions, symmetry may not be established. Their assumptions have broken down the belief of physicists in the universal symmetry of nature and triggered extensive academic discussions. At the heart of this theory is the notion that the rule of symmetry is not universal in nature and that symmetry may be broken in specific interactions, especially weak ones。

The introduction of this theory marks a major change in physics. In the past, it has been argued that stout is one of the basic symmetrys of nature, while the discovery of unstinting means that physicists need to reassess these so-called universal rules. In order to validate this theory, experimental validation has become a crucial step. In 1957, the experimental physicist oh ken hsiung carried out a sophisticated experiment that successfully demonstrated the lack of persistence in weak interactions. The experiment by wu ken hung provided empirical evidence for the theory of yang jin-ning and lee jung-do, which radically changed the understanding of symmetry in physics。
In a future chapter, we will describe in detail the experiment by wu ken hung to explore how she can reveal the truth about what she calls unsustainability through rigorous experimental design and further discuss the far-reaching implications of this discovery for modern physics, particle physics standard models and cosmology theory。
