In the field of quantum mechanics, I not just introduce fundamental concepts such as wave function, wave particle duality, Schrödinger equation,but also teach how to use functional analysis to quantitatively analyze quantum models with these abstract concepts. I connect these abstract theories to the optical and electrical experiences, and demonstrate through examples and cases how they affect results. As for algebra, I teach how to apply it to building models, solving equations, and analyzing data. The power of algebra lies in its universality. It is not only a tool for solving mathematical problems, but also a key to understanding the laws of nature. I am committed to linking this theory to practical problems, so that students can feel the practicality and beauty of mathematics in their learning.
