a thousand miles away in Jiangling, the relationship between distance and time. The apes on both sides of the strait can't stop crying, and the sound is generated and spread.
The canoe has passed Chung Shan Man, and the change of object position is called mechanical motion. First, the energy knowledge in ancient poetry 1. Su Shi's poetry "will bow like a full moon, look northwest, shoot Sirius".
in poetry, the energy conversion is the conversion of elastic potential energy into kinetic energy. 2. Li Bai's poem "Flying down three thousands of feet, it is suspected that the Milky Way has set for nine days".
The waterfalls in poetry contain great mechanical energy. Second, the knowledge of reference objects in ancient poetry 1. Mao Zedong's poem "Sitting on the ground and traveling 8, miles a day, patrolling the sky and looking at thousands of rivers" is that "sitting on the ground" is static relative to the ground, while "walking on the day" is moving relative to the sun.
2. In Li Bai's poem "Looking at Tianmen Mountain", it is written that "the green hills on both sides of the strait are opposite, and the lonely sails are coming from the sun". "Green hills are facing each other" is based on the ship, and "Lonely sails are coming from the sun" is based on the river bank.
3. In the lyrics of "Sparkling Red Star", "Little bamboos row in the middle reaches of the river and walk on both sides of the towering green hills". "the middle reaches of the bamboo raft river" takes the earth as the reference, while "walking on both sides of the castle peak" takes the ship as the reference.
4. "A strong wind blew the well outside the fence last night.". The well was blown away, and the fence was used as a reference outside the fence.
Third, the theoretical knowledge of heat and molecular dynamics in ancient poetry 1. In Lu You's "Village Living in Mountain Happiness", "The flower smells like a sudden warmth, and the magpie sounds like a new sunny day through the trees". In poetry, "the smell of flowers attacks people" is the result of the irregular movement of aromatic oil molecules secreted by flowers, and the temperature affects the intensity of molecular movement.
2. In Zhang Xu's "Stay in the Mountains", "Even if there is no rainy color in Enigmatic, clothes are stained in the depths of the areola". -formation of dew (liquefaction).
3. Bai Juyi's "Ode to the Mujiang River": "On the third night of September, the dew is like a pearl and the moon is like a bow"-the formation of dew (liquefaction). 2. famous sayings about learning physics
1. judge the beauty of heaven and earth and analyze the reason of everything. -Zhuangzi
2. The laws of physics cannot be obtained by "thinking" alone, but we should also devote ourselves to observation and experiment. -Planck
3. Interaction is the first thing we encounter when we look at the whole moving matter from the point of view of modern natural science. Natural science has confirmed it. . Interaction is the real ultimate cause of things. -Engels
4. Nature and its laws are hidden in the dark; God said, let Newton go! So everything was illuminated. —— Pope
5. Experiment can overturn theory, but theory can never overturn experiment. -Ding Zhaozhong
6. Mechanics is a science about movement, and its task is to describe the movement in nature in a complete and simple way. -Kirchhoff
7. The Principle (Newton's) will become an immortal monument of profound wisdom, which shows us the greatest law 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
8. 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
9. Science is an art that can be answered. The frontier of science is a brand-new territory between solvable and difficult, known and unknown. Scientists working in this field try their best to push the solvable boundary towards the difficult direction and try their best to reveal the unknown field. -Peter Meneva
1. Electricity has changed our way of life and produced a huge engineering application field. -Emilio Seguri
11. The most obvious phenomenon in the experiment of electricity and magnetism is the interaction between objects at a considerable distance 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
12. "Mr Faraday, what's the use of it?"
"ah, sir, maybe it won't be long before you can collect taxes on it."
-Dialogue between British Chancellor of the Exchequer Glass and Faraday
13. Send high-voltage current through ordinary wires to a long distance that has never been dreamed of so far with little energy loss, and use it at that end. . This discovery makes the industry get rid of all the boundaries stipulated by local conditions almost completely, and makes the application of remote water power possible. If it is only beneficial to the city at first, it will eventually become the most powerful lever to eliminate the opposition between urban and rural areas. -Engels
14. Without today's basic science, there will be no tomorrow's application of science and technology. -Li Zhengdao
15. Science is a method that teaches people how some things are understood, what they don't know, and how much they know now. . -Fei Enman
16. Water waves leave the place where they are produced, but the water there does not leave, just like the wheat waves set off by the wind in the fields. We saw that the wheat waves rolled towards the fields, but the wheat remained in its original place. -Leonardo da Vinci
17. People who stick to the old theory of light had better start from its own principles and put forward experimental explanations. Moreover, if his efforts fail, he should admit these facts. -Thomas Yang
18. 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
19. Going up and down everywhere, going back and forth between ancient and modern times. -Shi Jiao
2. Imagination is far more important than knowledge, knowledge is limited, and imagination can protect the whole world. -Einstein
21. The history of science is not only a series of facts, rules and subsequent mathematical descriptions, but also a history of concepts. When we enter another new field, we often need new concepts. -Planck
22. Walking on two legs in scientific examination, one is theory and the other is experiment. Sometimes one leg walks in front, and sometimes the other leg walks in front. Only by using two legs can we move forward. -Millikan
23. The interaction between gravity, electricity and magnetism can be clearly shown in a far place, so it 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
24. The development of our thoughts often comes from curiosity in a sense. -Einstein
25. Gunpowder, compass and printing-these are the three great inventions that predicted the arrival of bourgeois society. . The compass opened the world market and established a colony. . -Marx 3. Famous sayings about physics
If you give me a fulcrum, I can move the earth.
Archimedes' truth has such power. The more you want to attack it, the more your attack enriches and proves it. The earth under our feet is still turning! Galileo Galileo Galileo (1564-1642) If I ever saw farther, it was because I stood on the shoulders of giants.
I don't know what the world thinks of me. I just feel like a boy playing at the seaside. Sometimes I am happy to find a smooth stone or a beautiful shell, but the ocean of truth is still in front of me without being discovered. -Newton Sir Isaac(1643-1727) All sciences are either physics or stamp collecting.
-Rutherford Rutherford Ernest(1871-1937) The most incomprehensible thing about the universe is that it is understandable. God can't roll dice.
All scientific and technological efforts always focus on benefiting mankind and caring about the fate of mankind. In terms of understanding the truth, anyone who pretends to be an authority will surely collapse in the laughter of God! -Einstein Albert Einstein(1879-1955) The beauty of the equation, It is far more important than conforming to the experimental results. Science is concerned only with observable things and that we can observe an object by letter it interaction with some outside influence. ONL. Y questions about the result of experiments have a real significance and it is only such questions that theoretical physics has to consider. —— Dirac Paul Adrien Maurice Dirac(192-1984) I can tell you with certainty that no one really understands quantum mechanics. I can safely said (that). No body understands quantum theory. I believe that a scientific looking at non-scientific problems is just as dumb as the next guy. Physicists always think that all you need to do is: What will happen given such conditions? It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experience, it's wrong. No matter how smart you are, no matter how perfect your theory is, if it doesn't conform to reality, it is wrong. -Feynman Richard Phillips Feynman (May 11, 1918 * *—February 15, 1988 * *) Some students often ask me what is the key to success in doing physics work. I think the elements can be summarized into three P's: perception, persistence and power.
perception-eye, if you see something, you must hold on to it; Persistence-persistence, if you see it right, you must persist; Power-power, with power, you can break through the customs, and you have to break through when you encounter difficulties. -Yang Zhenning hopes that your younger generation can share the heat and shine like candles, and contribute to the great cause of mankind faithfully and practically.
-Faraday A=X Y Z A stands for success, x stands for hard work, y stands for correct method, and z stands for less empty talk. Einstein Nothing in nature can last forever.
-Galileo, at the age of 2, will dominates everything; At the age of thirty, wit dominates everything; At forty, judgment is everything. Franklin If you just give me a fulcrum, I can move the earth-Archimedes. 4. Poems about physics
First, the peaks reflect the mountains floating, and there is no water, no mountains and no ecstasy. -Modern Wu Mai's Landscape of Guilin
Physical principle: reflection and refraction of light.
The mountains are stacked in the water, and there are reflections of the mountains in the water. There is no mountain that is not attractive, and there is no water that is not attractive.
second, Hanshan Temple outside Gusu City, the midnight bell arrives at the passenger ship. -Tang Zhang Ji's
Physical principle: sound propagation.
In the lonely and quiet Hanshan Temple outside Gusu City, the sound of ringing bells reached the passenger ship in the middle of the night.
third, the green hills on both sides of the strait are opposite, and the lonely sails are coming from the sun. -Tang Li Bai's "Looking at Tianmen Mountain"
Physical principle: Compared with the green hills on the ground, it is static, but with the moving ship as the reference, the green hills become moving, with the river bank as the reference, and the solitary sails come from the sun.
translation: the beautiful scenery of the confrontation between the green hills on both sides of the strait is neck and neck, and I met a lonely boat from the horizon.
fourth, in April, the peach blossoms in the mountain temple are in full bloom. -Tang Bai Juyi's Peach Blossom in Dalin Temple
Physical principle: The higher the terrain, the slower the temperature rises. In the same season, the temperature in the mountains is lower than that in the mountains.
In April on earth, all the flowers have withered, and the peach blossoms in the ancient temples in the mountains have just bloomed.
5. how the Yellow River's waters move out of heaven, entering the ocean, never to return. -Tang Li Bai's "Coming into Wine"
Physical principle: water cycle.
The water of the Yellow River rushed from the sky, and the waves rolled straight to the East China Sea and never came back. 5. What are the famous sayings about physics
