Physicists often sum up a set of scientific research methods when making major scientific discoveries. For example, Galileo first embarked on a research road characterized by accurate mathematical analysis and summary of experimental data, using idealized methods in experimental design and based on reliable facts.

Newton was the first scientist who applied mathematical methods to systematically sort out physical theories, organized personal research results with systematic mathematical methods, and made it rise from experience accumulation to rational generalization, from fragmentary knowledge to systematic theory.

Franklin, Ohm, Faraday and Maxwell skillfully used analogy method in the process of establishing cell electro-hydraulic theory, Ohm's law, power line and electromagnetic field theory. These are precious wealth accumulated by human beings in understanding nature. As Laplace, a famous mathematical physicist, pointed out: "It is more important to know a gifted research method than to find yourself."

Therefore, in physics teaching, if a series of thinking methods summarized in the history of physics are introduced to students and mastered, it will be very helpful to cultivate students' ability to analyze, deal with and solve problems, to think creatively, to explore new knowledge, to get rid of the "sea of questions" and to reduce the learning burden.
