1. 12 ancient poems, proverbs, and sayings about physics
The refraction and reflection of light among the colorful clouds of Bai Di.
A thousand miles to Jiangling in one day, the relationship between distance and time. The apes on both sides of the Taiwan Strait can't stop crying, the generation and spread of sound.
The boat has passed the Ten Thousand Mountains, and the change in the position of the object is called mechanical motion. 1. Energy knowledge in ancient poetry 1. Su Shi's poem "Can draw the eagle's bow like the full moon, look northwest, and shoot at the wolf".
The energy conversion involved in the poem is the conversion of elastic potential energy into kinetic energy. 2. Li Bai's poem "Flying down three thousand feet, it seems that the Milky Way is falling from the sky."
The waterfall in the poem contains huge mechanical energy. 2. Reference knowledge in ancient poetry 1. Mao Zedong’s poem “Sitting on the ground and walking eighty thousand miles in a day, surveying the sky and looking at thousands of rivers” is, among which “sitting on the ground” means that it is stationary relative to the ground, while “walking in a day” means is moving relative to the sun.
2. In Li Bai's poem "Looking at Tianmen Mountain", he wrote that "the green mountains on both sides of the strait come out facing each other, and the solitary sail is coming from the sun." "The green mountains come out relative to each other" uses the boat as a reference, and "the solitary sail comes by the sun" uses the river bank as a reference.
3. In the lyrics of "Shining Red Star", "Small bamboo rafts line the middle reaches of the river, walking on both sides of the towering green mountains." "The middle reaches of the Zhupai River" uses the earth as a reference, while "walking on both sides of the Qingshan Mountains" uses a boat as a reference.
4. "A strong wind blew the well outside the fence last night." The well was blown away and the outside of the fence was based on the fence.
3. Theoretical knowledge of thermal science and molecular kinetics in ancient poetry 1. In Lu You's "Village Living in the Mountains", "The flower energy strikes people and they know it is suddenly warm, and the magpies sing through the trees to rejoice in the new sunshine." The "astonishing flower scent" in the poem is the result of the irregular movement of aromatic oil molecules secreted by flowers, and temperature affects the intensity of molecular movement.
2. In Zhang Xu's "A Guest in the Mountains", "Even if the sky is bright and there is no color of rain, the clothes are still stained deep in the areola." ——The formation of dew (liquefaction).
3. Bai Juyi's "Ode to the Dusk River" "Poor on the third night of September, the dew is like pearls and the moon is like a bow" - the formation (liquefaction) of dew. 2. Famous aphorisms about learning physics
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

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 variety 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, 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.

12. "Mr. Faraday, what is the use of it (electromagnetic induction)?"
"Ah, sir, maybe you can control it soon." Tax."
——Conversation between British Chancellor Glass and Faraday
13. Transmit high-voltage current through ordinary wires with little energy loss. I don't dare to think about it from a long distance and use it at that end. . This discovery freed industry almost completely from all limits imposed by local conditions and made possible the application of extremely remote water power. If at first it was only beneficial to the city, in the end it will become the most powerful way to eliminate the antagonism between urban and rural areas. lever. ——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

25. Gunpowder, compass, and printing—these are the three great inventions that heralded the arrival of bourgeois society. . The compass opened world markets and established colonies. . ——Marx 3. Famous quotes about physics
If you give me a fulcrum, I can move the earth.
Archimedes Truth has such power that the more you try to attack it, the more your attacks enrich and prove it. The earth beneath our feet is still spinning! ——Galileo Galilei(1564-1642) If I have ever seen further, it is because I stand on the shoulders of giants.
I don’t know what the world thinks of me. I just feel like a boy playing on the beach. Sometimes I am happy to find a smooth stone or a more beautiful shell, but the ocean of truth is still there. My front without being noticed. ——Newton Sir Isaac (1643-1727) All science is either physics or stamp collecting.
——Rutherford Ernest (1871-1937) The most incomprehensible thing about the universe is that it is understandable. God doesn't play dice.
All scientific and technological efforts are always aimed at benefiting mankind and caring about the destiny of mankind. In terms of understanding the truth, anyone who considers himself an authority will surely be laughed at by God. Downfall! ——Albert Einstein (1879 - 1955) The beauty of equations is far more important than conforming to experimental results. Science is concerned only with observable things and that we can observe an object by letting it interact with some outside influence. Only Questions about the result of experiments have a real significance and it is only such questions that theoretical physics has to consider. ——Paul Adrien Maurice Dirac (1902 - 1984) I can tell you with certainty: No one really understands quantum mechanics. I can safely said (that) no body understands quantum theory. I believe that a scientist looking at nonscientific problems is just as dumb as the next guy. What's the result? It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong. Actually, then it is wrong. --Richard Phillips Feynman (May 11**, 1918-February 15**, 1988) My classmates often ask me what are the key factors for success in physics work? I think the elements can be summarized into three P's: Perception, Persistence, and Power.
Perception——Perception, if you see something right, you must hold on to it; Persistence——Persistence, if you see it right, you must persist; Power——Strength, with the strength, you can overcome obstacles and encounter obstacles. When you encounter difficulties, you have to push through them. —— Yang Zhenning I hope that you, the younger generation, can be like candles that illuminate people, have warmth and light, and contribute your strength to the great cause of mankind loyally and down-to-earth.
—— Faraday A=X Y Z A represents success, X represents hard work, Y represents the correct method, and Z represents less empty words. ——Einstein Nothing in nature remains permanent.
- Galileo Galilei: At the age of twenty, will dominates everything; at the age of thirty, wit dominates everything; at the age of forty, judgment dominates everything. ——Franklin As long as you give me a fulcrum, I can move the earth. ——Archimedes. 4. Poems about physics
