Chapter one: physics education motto 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
I think the elements can be summarized as three P's: perception, persistence and strength. Perception: eyes, what you see, you must hold on tight; Persistence: Persistence, if you see it right, you must persist; Strength: strength, with strength, we can break through, and we will break through when we encounter difficulties. —— Yang Zhenning
I hope you young people can share the heat and light like candles and make loyal and practical contributions to the great cause of mankind. Faraday
Nothing in nature is eternal. Galileo
People, at the age of twenty, will dominate everything; At the age of thirty, wit dominates everything; At forty, judgment is everything. Franklin
What is really valuable does not come from ambition or simple sense of responsibility; But from the love and focus on people and objective things. -Einstein
This extremely beautiful cosmic system can only be produced under the jurisdiction of the wise and the strong.
If there is no other evidence to prove the existence of God, I can be convinced by my thumb alone.
If I have made any new contributions and discoveries, it is not because I have any genius, but because I have more patience to study. newton
Science can only decide how, not how. Beyond its scope, we still have to judge various values. The most beautiful thing is mysterious, which is the root of art and science. We have only two views on life: neither is a miracle, or both are miracles. I believe in the latter. -Einstein
The secret of success lies in doing more. —— Yang Zhenning
If no one makes all the mistakes, the final result is of course correct. Tsung Dao Lee
Wasting time is the worst thing. Samuel Chao Chung Ting
One is not fame and the other is not profit, but the goal of the work is to reach the world advanced level. -Deng Jiaxian
My family name is Qian, but I don't love money. -Qian Xuesen
We don't have to be geniuses, but we know our goals and plans; We will often be frustrated, but don't lose enthusiasm. -Chu Wendi
If I see farther than others, it is because I stand on the shoulders of giants. newton
When you face the possibility of death, you will realize that life is precious and you have a lot to do. -Hawking
For example, honor is like a toy, you can only play it, but you can never keep it forever, otherwise you will accomplish nothing. Marie Curie
Honor is not the driving force of struggle. Chien-shiung Wu
The joy of my life lies in constantly exploring the unknown world. If I can know a little about it and make some achievements, I will be very satisfied. joule
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, you are hit by a bouncing shell. The difficulty encountered by Thomson model is vividly described, that is, the atom cannot be a sphere with uniform mass distribution 1 angstrom. Rutherford
Chapter two: physics education motto 1. Judge the beauty of heaven and earth and analyze the principle of everything. -Zhuangzi
2. Physical laws can't be obtained only by "thinking", but also by observation and experiment. -Planck
3. From the viewpoint of modern natural science, the first thing we encounter is interaction. Natural science has proved that ... interaction is the real ultimate cause of things. -Engels
4. Nature and its laws are hidden in the darkness; God said, let Newton go! So everything is lit up. -Popper
Experiments can overthrow theories, but theories can never overthrow experiments. Samuel Chao Chung Ting
6. Mechanics is a science about movement, and its task is to describe the movement in nature completely and simply. -Kirchhoff
7. This principle (Newton's) will become an immortal monument with profound wisdom, which shows us the greatest law of the universe and is a masterpiece that is higher than all other products of human thought at that time. This simple and universal law and the discovery of huge and diverse objects add luster to human wisdom. Laplace
8. The task of physics is to discover the universal laws of nature. Because one of the simplest forms of this law is the invariance of a 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 field, between solvable and difficult, known and unknown. Scientists working in this field try their best to push the solvable boundary in a difficult direction and try their best to reveal the unknown field. Peter Meneva
10. Electricity has changed our way of life and produced a huge engineering application field. Emilio Seguri
1 1. The most obvious phenomenon in electromagnetic experiments is the interaction between objects that are quite far apart. 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?"
"Ah, sir, maybe it won't be long before you can tax."
-Dialogue between British Chancellor of the Exchequer Glass and Faraday
13. The discovery that high-voltage current is transported to a long distance that ordinary wires can't even imagine with little energy loss and used at that end makes the industry almost completely get rid of all the boundaries stipulated by local conditions, making it possible to apply hydraulic power in very remote places. 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. Tsung Dao Lee
15. Science is a method to teach people how to understand something, what they don't know and how much they know now ... Fei Enman
16. The water wave left the place where it was produced, but the water there did not leave, just like the wheat wave in the field. We saw waves of wheat rolling towards the fields, while the wheat stayed where it was. -Leonardo da Vinci
17. Those who adhere 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 Young
18. gunpowder, compass and printing-these three great inventions foreshadowed the arrival of bourgeois society ... the compass opened the world market and established a colony ... Marx
19. Up and down the quartet, Yu Yue, ancient and modern exchanges, Yuezhou. -Shijiao
20. Imagination is far more important than knowledge, knowledge is limited, and imagination can protect the whole world. -Einstein
2 1. 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. Science exams walk on two legs, one is theory and the other is experiment. Sometimes one leg walks in front, and sometimes the other leg walks in front. You can only move forward with two legs. Millikan
23. The interaction between gravity, electricity and magnetism can be clearly shown in far places, so it can be observed with the naked eye; But there may be other interactions, and their distance is too small to be observed. newton
24. The development of our thoughts, in a sense, often comes from curiosity. -Einstein
