Faber's scientific spirit is mainly reflected in the following aspects:
1. Experimentalism: Fable emphasized that experiment is the basis of scientific research, and only through experiments can we gain real knowledge. He has also carried out a lot of experiments, such as studying the refraction and reflection of light.
2. Mathematical method: Faber believes that mathematics is the language of science, and only through mathematical methods can scientific theories be accurately expressed. He is also an excellent mathematician, who has put forward many important mathematical theorems.
3. Hypothesis and verification: Faber believes that scientific research should start from hypothesis and verify the correctness of hypothesis through experiments. He proposed two methods, "induction" and "deduction", for hypothesis and verification in scientific research.
4. Independent thinking: Faber emphasizes the importance of independent thinking, and believes that scientists should think independently, free from the shackles of traditional concepts and authority. He opposed following the authority and blindly following the crowd, and advocated free thinking and exploration.
5. Pragmatism: Faber believes that scientific research should serve the actual needs of human society and solve practical problems. He advocated combining scientific research with engineering practice to promote the development and application of science and technology.
