Quotes from physics celebrities:

1. Judge the beauty of heaven and earth and analyze the principles of all things. ——Zhuangzi

2. The laws of physics cannot be obtained by "thinking" alone, but should also be devoted to observation and experiment. ——Planck

3. Interaction is the first thing we encounter when we examine the entire moving matter from the perspective of modern natural science. Natural science confirms that...

Interaction is the true ultimate cause of things. ——Engels

4. Nature and the laws of nature are hidden in the dark night; God said, let Newton go! Then everything is illuminated. ——Pope

5. Experiments can overturn theories, but theories can never overturn experiments. ——Ding Zhaozhong

6. Mechanics is the science of motion, and its task is to describe the motion that occurs in nature in a complete and simple way. ——Kirchhoff

7. (Newton's) "Principia" will become an immortal monument to profound wisdom. It shows us the greatest law of the universe, which is higher than (at that time) mankind The masterpiece above all other products of thought, the discovery of this simple and universal law has given glory to human wisdom by the vastness and diversity of objects it embraces. ——Laplace

8. The task of physics is to discover universal laws of nature. Because one of the simplest forms of such a law is the invariance of a certain physical quantity,

so the search for conserved quantities is not only reasonable, but also an extremely important research direction. ——Laue

9. Science is an art that can answer questions. The frontier of science is a new frontier between the comprehensible and the incomprehensible, the known and the unknown. Scientists working in this field do their best to push the boundaries of what can be solved in unsolvable directions and do their best to reveal unknown areas. ——Peter Meneva

10. Electricity has changed our way of life and created a huge field of engineering applications. ——Emilio Segre

11. The most obvious phenomenon in the experiments of electricity and magnetism is the interaction between objects that are located at a considerable distance from each other. Therefore, the first step in turning these phenomena into science is to determine the magnitude and direction of the forces between objects. ——Maxwell

12. "Mr. Faraday, what is it (electromagnetic induction) used for?" "Ah, Sir, maybe you can tax it before long." - Britain Conversation between Chancellor Glass and Faraday

13. Transmit high-voltage current through ordinary wires with small energy loss to far distances hitherto unimaginable, and use it at that end ... This discovery freed industry almost entirely from all limits imposed by local conditions and made possible the application of extremely remote water power, which, if at first it was only beneficial to the cities, in the end it became the elimination of urban and rural areas. The most powerful lever of opposition. ——Engels

14. Without today’s basic science, there would be no tomorrow’s scientific and technological applications. ——Li Zhengdao

15. Science is a method that teaches people: how some things are understood, what else is unknown, and to what extent we understand what we understand now... ...——Feynman

16. The water wave leaves the place where it is generated, but the water there does not leave, just like the waves of wheat set off by the wind in the field. We saw waves of wheat rolling towards the fields, but the wheat still stayed in its original place. ——Leonardo Da Vinci

17. People who are stubborn about the old theory of light would be better off starting from its own principles and proposing experimental explanations. And, if he fails in this effort, he should acknowledge these facts. ——Thomas Young

18. Since Newton laid the foundation of theoretical physics, the greatest change in the axiomatic basis of physics was caused by the work of Faraday and Maxwell on electromagnetic phenomena. ——Einstein

19. The four directions above and below are called the universe, and the communication between ancient and modern times is called the universe. ——Xi Jiao

20. Imagination is far more important than knowledge. Knowledge has limits, but imagination can protect the entire world.

——Einstein 21. The history of science is not only a series of facts, rules and subsequent mathematical descriptions, it is also a history of concepts. When we enter a new field, we often need new concepts. ——Planck

22. Science walks on two legs, one is theory and the other is experiment. Sometimes one leg goes in front, sometimes the other leg goes in front. Only by using two legs can you move forward. ——Millikan

23. Gravity, electric interaction and magnetic interaction can be clearly displayed at very far places, so they can be observed with the naked eye; but there may be other interactions. The forces acting on them are so small that they cannot be observed. ——Newton

24. The development of our thoughts often comes from curiosity in a sense. ——Einstein
