Chương 420: Chapter 203: Excited Physicists

Without physics, mathematics would indeed be a discipline devoid of any real-world significance.

But precisely because we have time, space, length, weight, speed, volume, and so on, these physical concepts, mathematics becomes important.

The meaningful essence belongs to this world because it is made of matter, and exploring the mysteries of this world is inseparable from mathematics.

From pi to calculus.

From Newton's First Law to Einstein's general theory of relativity, the interpretation of physical aspects needs to be expressed in mathematical equations.

Taylor's Theorem is an important mathematical tool often used in studying the properties of complex functions, and engineers need to learn Taylor's expansion to design and optimize mechanical systems. Experienced engineers don't even need to memorize those complex formulas by rote— they can derive the necessary expansions simply by taking up pen and paper.

Structures in mathematics often have physical significance.
