Therefore, it is basically unpredictable, but paradoxically, there are certain laws, which are the product of accumulation over time, such as the wave theory of concrete arrangement. We only learn these things in order to choose the best method to solve the immediate problem when we encounter similar situations, with the aim of solving the problem with numbers instead of predictions.
Just like we are just a drop of water in the sea, we can know the general direction of the sea, but we can't judge the next moment when the waves roll up and down.
