Since Newton, people have been describing the physical world by mathematical means, and mathematics can be said to be a difficult point in the physical world. All our existing theories are a mathematical structure, but some mathematics can't find any use in physics, which makes scientists divided into several camps.

One school thinks that the physical world is just a mathematical framework and mathematics is the real reality, similar to Platonism.

Another school believes that mathematics is only a logical structure of human beings, which enables us to understand the physical world, but mathematics is not an objective truth, that is, without human beings, mathematics will not turn.
