Radium has the possibility of decay. If radium decays, it will trigger the mechanism to break the bottle containing cyanide and the cat will die. If radium doesn't decay, the cat will live. According to the theory of quantum mechanics, cats should be in the superposition state of dead cats and live cats because radioactive radium is in the superposition state of decay and non-decay. This dead and alive cat is the so-called "Schrodinger cat". However, there can't be a dead cat and a live cat, so you must open the container to know the result.
Schrodinger's Cat Hint
Schrodinger's Cat in Life refers to the certainty and uncertainty of things, that is, the two sides of things. For example, I'm going to do something soon, with a 50% chance of success or failure. In this case, it can be considered that this is Schrodinger's cat. In addition, if you throw a coin into the sky, you don't know whether it will fall heads or tails. Both possibilities are half. Before you open your hand, the state of this coin is also Schrodinger's cat.
This kind of uncertainty is common in life, not so rare. Schrodinger's cat is a more interesting and reasonable way to describe it. Some people even extended this to a certain extent, and finally got Schrodinger's method of picking up girls.
