Schrödinger’s full name is Erwin Schrödinger. He is an Austrian physicist and one of the founders of quantum mechanics. He developed molecular biology. Doctor of Philosophy, University of Vienna. Professor of the University of Zurich, the University of Berlin and the University of Graz. Schrödinger’s cat experiment is to put a cat in an opaque box, and then connect the box to an experimental device that contains a radioactive nucleus and a container filled with toxic gas. It is assumed that the radioactive nucleus will have The possibility of decay, if it decays, it will trigger the experimental device, open the container with the poisonous gas, thereby killing the cat. According to quantum mechanics, when the nucleus is not observed, the nucleus is in a superposition of decayed and undecayed. However, if the box is opened after an hour, the experimenter can only see “decayed nuclei and dead cats” or “undecayed” “The nucleus and the live cat” two situations. What does this superposition form mean, that is, the nucleus is both decayed and undecayed… It is a superposition of two states, and only when someone observes it, it will be shown as decay. Or there is no decay. If no one cares about him, he will always be in a superposition state, which is terrible, because the cat will enter a dead and alive state with the superposition of the atomic nucleus.

When you observe this electron, there is obviously only one observation result at a time. This does not mean that it was only in this position before. Because at this time of observation, we must use a probe, such as a photon, to hit him. This photon also carries a certain amount of energy. Therefore, while observing, we have actually changed its properties.

This law is obviously difficult to understand. So when scientists first discovered the quantum world, they were also puzzled by its laws. Some scientists even refused to recognize the authenticity of certain laws, such as the famous scientists Planck and Einstein. So Schrödinger invented the metaphor of “a cat in both states of life and death” to explain this superimposed state (two different properties exist at the same time). Well, when the box is closed, it means that we haven’t observed it yet and we are in an undisturbed state. This is that he is both alive and dead (note that it is not possible to be alive or possibly dead). Our action of opening the box is to measure it, which is equivalent to intervening in his state from the outside world, and his state is changed, thus collapsing to a state, either alive or dead.
