2. Those who insist on the old theory of light, it is best to put forward an experimental explanation based on its own principles. Moreover, if his efforts fail, he should admit these facts. Thomas Young
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
4. Experimental physics is closely related to theoretical physics. It is impossible to do experiments without theory, but it will not progress if we only stay in theory without experimental science. Samuel Chao Chung Ting
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 get 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
6. The beauty of the equation is far more important than conforming to the experimental results. -Dirac
7. Physicists always think that what you need to do is: given such conditions, what will happen? Feynman
8. The principle (Newton's) will become an immortal monument with profound wisdom, which shows us the greatest universal law and is a masterpiece 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
9. Experiments can overthrow theories, but theories can never overthrow experiments. Samuel Chao Chung Ting
10, judge the beauty of heaven and earth, and analyze the principle of everything. -Zhuangzi
1 1. The most obvious phenomenon in electrical and magnetic 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, scientists do not rely on individual thoughts, but integrate the wisdom of millions of people. Everyone thinks of a problem, everyone does a part of the work and joins it in the great knowledge building being built. -Rutherford
13, I can tell you for sure that no one really understands quantum mechanics. -Dirac
14, all science subjects are either physics or stamp collecting. Rutherford
15, the string, like a half claw that should have appeared in physics in 2 1 century, accidentally fell down in the 20th century. -Witton
16, the interaction of 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 too small to be observed. newton
17, the laws of physics can not be drawn by "thinking" alone, but also by observation and experiment. -Planck
18, since Newton laid the foundation of theoretical physics, the biggest change in the axiomatic foundation of physics was caused by Faraday and Maxwell's work on electromagnetic phenomena. -Einstein
19, nature and its laws are hidden in the darkness; God said, let Newton go! So everything is lit up. -Popper
