First, mathematics is the foundation of all natural sciences, and physics, chemistry, bio-economics and so on are inseparable from mathematics; The infiltration and participation of mathematics make other disciplines become science, and mathematics makes them a strict system.
Second, the role of mathematics is everywhere, the invention of computers (mathematician von Neumann and others), the establishment of information theory (mathematician Shannon), the establishment of classical mechanics by Newton (one of the four mathematicians in the world), the establishment of general relativity (after Einstein re-studied mathematics-Riemann geometry), matrix mechanics in quantum mechanics and so on.
Third, the backwardness of modern China is not unrelated to the backwardness of mathematics (the tradition of attaching importance to literature and neglecting reason in ancient China seriously restricted the development of science and technology in China, and also kept China in a state of stagnation in feudal society for a long time). The vigorous development of Europe after the Renaissance is closely related to mathematics, especially to the establishment of Newton, Leibniz calculus, Descartes analytic geometry and the work of a large number of mathematicians such as Fermat.
Fourthly, the development of mathematics plays an increasingly important role in predicting and understanding the world. The discovery of chaos theory is found by solving mathematical equations. The function of fractal theory in describing the objective world, such as human blood vessels, nerves and so on.
The rest, you are free to play.
