Mathematics is abstract, and there are no models in life, which requires us to see as many questions as possible, and do logic from multiple angles by doing more questions, so that we can do logic quickly when we see other questions, and answer questions through reasoning and calculation. Physics has models for reference in real life. We generate models in our minds and analyze every process of the models. Every process in physics has a corresponding formula and these processes can solve problems together. I think the study of physics is analysis.
