Mathematics evolved from philosophy, which can be said to be a branch of philosophy of language. It expresses the world in a specific language. Its main research object is the relationship between things in space, and it is a science to study spatial relations. People abstract some concepts from the relationship between things in the objective world to express the relationship between things, and further mark them with specific symbols, so convention has developed into a modern highly abstract and highly symbolic science.

Physics is a branch of mathematics, which inherits a system of mathematics in space and adds time parameters as an important reference to study the relationship between things, thus forming a knowledge that mainly studies the relationship between things in time and space. So physics is the extension and development of mathematics. However, physics is mathematical in nature, because if time is regarded as a new dimension, it will fall into a space system when it is combined with the known three-dimensional space, so that things in time and space can be studied with the mathematical space language system. This is also the reason why Einstein established the concept of four-dimensional space-time and invented the theory of relativity, in order to study the relationship between things in the universe with mathematical tools.

Mathematics as a philosophy of language, the source of science is to explore the stability and invariance of the relationship between objective things, tell them these properties, and sum up experience to explore other space things, which is static. Therefore, science has a characteristic of pursuing stability, so it will introduce a serious, harsh, rigid and mechanized character, and of course, it also has a good side, rigorous and disciplined character.

Why science and engineering men are so ignorant of amorous feelings, that is, they have inherited this idea!
