Before explaining what is the highest state of Tai Chi, there is a logical premise, that is, what is the highest state of this world, that is, what is the truth of this world?
Please take a minute to introduce you to the truth of this world, and maybe you will understand it. Our story begins in the 20th century, when physicists began to struggle with the question, is light a wave or a particle? In order to find out the truth, they decided to do an experiment by using a machine gun that emitted photons at a double slit if the beam was made up of particles. When it is presented on the screen through a double slit, it will inevitably leave two bars, which is the same reason that a bullet will leave a hole after hitting the target. If the beam is made up of pure waves, there will be multiple stripes on the screen like zebra crossings. According to the wave theory, when water waves pass through a gap, two wave sources are formed. The intensity of the crests is superimposed, the peaks and troughs are canceled out, and finally zebra crossings will appear on the screen. To put it simply, the two-bar pie wins, and the zebra crossing wave wins
First experiment: Aim a photon machine gun at a double slit and fire. As a result, standard zebra crossings; The second experiment: switch the photon machine gun to the burst mode, although only one photon is fired at a time, but after a period of accumulation, there are still interference fringes, which makes people puzzled, obviously only one of the two slits has photons. So who is this photon interfering with? Is he interfering with himself? At this point, the first question arises, why is this happening? This is the first law of quantum mechanics, the principle of superposition。This made physicists particularly curious and began to try. The third experiment, in front of the screen to add two detectors, one side left and right rows, which side of the detector to see the photon, it means that the photon passed through which slit, through the detector observation data found that the photon is indeed only from the left or right slit, a single through, just when the scientist thought that everything was the truth, but suddenly the scalp was numb, but on the screen saw the obvious two bars. Why is this happening? Why is it observed with a detector, it has changed from a zebra crossing to two bars?This is the second law in quantum mechanics: the observer principle。If you observe it, it will cause the superposition state to collapse and see a sure result. Whether it's a wave or a particle seems to be in the past. Just when they were arguing,Albert Einstein came up with a bold hypothesis, the quantum hypothesis of light. Later, it evolved into wave-particle duality, that is, light appears to be wave-like when it travels, but it shows particle behavior when it is measured. But I want to emphasize that wave-particle duality is only a property and not an essence, and in layman's terms, it can express the properties of both waves and particles. And the variables in this are only due to the different ways of observation. That's it. All doubts seem to be solved, and this is the famous "double-slit interference experiment". However, what happened decades later became the key to the collapse of classical physics, and that isIn 1979, Wheeler proposed a delayed choice experiment。They continued to repeat the previous double-slit interference experiment, but this time only with a screen and no camera. Physicists calculate the timing of the photon passing through the slit, and when it passes through, the detector is added when it finally falls in front of the screen, and the result is that no matter how fast the detector is, as long as it is finally added, there must be two bars on the screen. Conversely, if there is a camera at the beginning, even if it is removed at the last minute, the screen must be a zebra crossing. Cause.
It's interesting to see that the detection device affects the photons after they have passed through the interference gap, but it can affect the state of the photons through the interference gap. Theoretically speaking, the piercing is the cause in the front, and the effect is the effect after being detectedAccording to the law of causality in classical physics, cause can determine effect, but in this experiment, effect can determine cause. In other words, in the microcosm, the future can indeed change the past。So far, no one has been able to give a definite explanation for this problem. But to paraphrase Bohr, no physical quantity exists objectively until the observation happens, and you will find that all of this can be explained. That's where quantum mechanics comes in, where they explain the double interference experiment and the delayed choice experiment so perfectly. After delaying the selection experiment, no one in the physics community no longer believes in quantum mechanics.
In 947, Bohr designed the Chinese Tai Chi pattern for his family crest, and he believed that the Tai Chi diagram was the most perfect explanation of quantum mechanics. The ancient Chinese had already comprehended the laws of the operation of the whole world thousands of years ago, from the macrocosmic universe that knew the big and the outside, to the elementary particles in the microscopic realm that was small and invisible, and the laws of its development and change were all in Tai Chi. This is the highest state of Tai Chi.
