1, the correct view is that mathematics not only has truth, but also has extraordinary beauty, a beauty as cold and simple as sculpture, a beauty that does not need our weak nature to perceive, a beauty that is not as ornate as painting and music, and a strict perfection that only the greatest art can have. Russell (British philosopher, mathematical logician, the main founder of analysis, the advocate and organizer of the world peace movement.

2. Being good at "retreating", retreating enough and retreating to the original place without losing its importance is a trick to learn mathematics well. Hua.

3. Mathematics is a tool especially suitable for dealing with any abstract concept, and its power in this field is infinite. For this reason, a book about emerging physics, as long as it is not a pure experimental description, must be a math book in essence. Dirac.

Mathematics is the key to science and the beauty of the universe. Kepler (German astronomer and optician).

5. Mathematics has two sides. On the one hand, it is a strict science of Euclid. From this perspective, mathematics is a systematic deductive science. On the other hand, mathematics in the process of creation looks like an experimental inductive science. Paulia (mathematician and math educator).

6. The same is true of "difficulty". Facing the cliffs, you can't see a crack in a hundred years, but you can cut it inch by inch and foot by foot with an axe. If you keep accumulating, a leap will come and a breakthrough will follow. Hua (a world-famous mathematician, the founder and pioneer of China's research in analytic number theory, matrix geometry, canonical group and self-safety function theory. ).

7. Think, keep thinking, wait for the dawn, and gradually see the light. If I have contributed to the world, it is not because of anything else, but because of my hard work and persistent thinking. Newton (English mathematician, astronomer and physicist).
