Physics was a discipline that studied the laws of the movement of matter and the basic structure of matter.
The universe was like a series of infinite numbers, say [1,2,3,5,7,11,13…], and physics was to study the laws and patterns of this series of numbers.
When science was at its beginning, when people were still arguing about 1 and 2, a physicist sitting under an apple tree was lucky enough to count to 3, so he thought that "The series of numbers is 123456… It is composed of all natural numbers".
However, due to the advancement of science and technology, observation methods had also improved.
Einstein, the physicist of the new era quickly discovered that the fourth number was not 4 but 5, The laws summarized by Newton were only applicable to the first three numbers.
In order to make his theory seem more convincing, Einstein had been observing the seventh number, which was the number 13. Based on the observed phenomenon, this conclusion was made:
