There is always a big difference between the truth and the appearance of things in the world.

Insight is like playing chess. A novice thinks that he has thought about several moves, but an experienced player seems to be very ordinary. A novice thinks hard, but an experienced player is flexible and easy. This is true for playing chess, and so is scientific research. If you want to ask the reason, no other reason is that the talents of experienced people are at a high level. Scientific insight is manifested in quickly grasping the essence through phenomena and quickly finding out the common causes or connections between seemingly different things. This is inseparable from the accumulation of knowledge and practice, and also requires higher comprehensive observation and judgment. Without gradual change, there will be no qualitative change; without quantity, there can be no quality. Only by studying, accumulating and practicing more in daily life can we make high-level discoveries. ——Einstein.
