1. Nature and its laws are hidden in the dark; God said, let Newton go! So everything was illuminated. -Pope

2. Since Newton laid the foundation of theoretical physics, the greatest change in the axiomatic foundation of physics was caused by Faraday and Maxwell's work in electromagnetic phenomena. -Einstein

3. This is the most incredible thing that has happened to me in my life, just like you bombard a piece of paper with a 15-inch cannon and you are hit by a bouncing shell. The difficulty of Thomson model is vividly described, that is, atoms cannot be spheres with uniform mass distribution and size of 1 angstrom. -Rutherford

4. Strings are like a half claw that should appear in physics in the 21st century, but accidentally fell in the 2th century. -witton

5. Physicists always think that all you need to do is: What will happen given such conditions? -Feynman

6. The task of physics is to discover universal laws of nature. Because one of the simplest forms of this law is the invariance of a certain physical quantity, it is not only reasonable but also an extremely important research direction to seek the conserved quantity. -Laue

7. The laws of physics cannot be obtained by "thinking" alone, but we should also devote ourselves to observation and experiment. -Planck

8. I can tell you with certainty that no one really understands quantum mechanics. -Dirac

9. Gravitation, electric interaction and magnetic interaction can be clearly displayed in a far place, so they can be observed with the naked eye; But there may be other interactions, and their distance is so small that it is impossible to observe. -Newton

1. All sciences are either physics or stamp collecting. -Rutherford

11. Experimental physics is closely related to theoretical physics. It is impossible to engage in experiments without theory, but it will not advance if you only stay in theory without experimental science. -Ding Zhaozhong

12. Experiments can overthrow theories, but theories can never overthrow experiments. -Ding Zhaozhong

13. Judge the beauty of heaven and earth, and analyze the principle of everything. -Zhuangzi

14. Scientists don't rely on individual thoughts, but integrate the wisdom of thousands of people. All people think of a problem, and each person does part of its work and adds it to the great knowledge building being built. -Rutherford

15, people who are stubborn about the old theory of light, it is best to start from its own principles and put forward the explanation of the experiment. Moreover, if his efforts fail, he should admit these facts. -Thomas. Yang

16. Give me a fulcrum, and I can pry up the whole earth. -Archimedes

17. The beauty of the equation is far more important than conforming to the experimental results. -Dirac

18. The most obvious phenomenon in the experiment of electricity and magnetism is the interaction between objects that are quite far away from each other. Therefore, the first step to turn these phenomena into science is to determine the magnitude and direction of the force between objects. -Maxwell

19. (Newton's) Principles will become an immortal monument of profound wisdom, which shows us the greatest laws of the universe and is a masterpiece higher than all other products of human thought at that time. The discovery of this simple and universal law, with its huge and diverse objects, gives glory to human wisdom. -Laplace
