What exactly is "Schrodinger's cat" and why is it so hot?

The fire in Schrodinger's Cat can be said to be one of the appearances of science entering the homes of ordinary people. It shows that ordinary people are also curious about the quantum field, although this curiosity only stays on the surface.

"Schrodinger's cat" is a hypothetical experiment put forward by scientist Schrodinger. A cat is kept in a closed container, which contains a very small amount of radium (a single radium atom) and a bottle containing cyanide. Radium and the bottle containing cyanide are connected by a simple device. Once radium decays, cyanide will be released and the cat will die. However, because the decay of radioactive elements only conforms to the statistical law, radium atoms may decay in the next second, or it may decay after 10 thousand years, which is completely uncertain by any method. When you can't observe the situation in the container, the life and death of the cat can't be determined. So is this cat alive or dead? Schrodinger believes that the cat at this time is neither alive nor dead, but in a state called quantum entanglement.

Of course, Schrodinger's cat is just a popular version of the uncertain relationship (although there is nothing wrong), in order to explain the latest scientific research results to the public. The complete version of the uncertain relationship is still very complicated. Einstein was wrong in those years. ...

At present, people who own cats occupy an increasingly important position in our lives, and Schrodinger's Cat is just in line with the hot topic in this period. Although our life is contaminated with a little knowledge of quantum field, in fact, most people just blindly follow the trend. There is still a long way to go to really let everyone say a few words about quantum theory.
