1, the essence of mathematics is its freedom.

2. In the field of mathematics, the art of asking questions is more important than the art of answering questions.

3. Numbers rule the universe.

God created integers, and the rest are man-made.

5. God is a mathematician.

6. Anyone who doesn't know that the diagonal side of a square is an incommensurable quantity is not worthy of this title.

For centuries, the simple combination of integers has been the source of new students in mathematics.

8. The more detached a mathematician is, the better.

9. The incomparable eternity and omnipotence of mathematics, as well as its independence in time and cultural background, are the direct consequences of its essence.

10, we find that every new group is mathematical in form, because we can't have other guidance.

1 1, the grand structure of the universe now appears as a pure mathematician.

12, countability is the world that rules the whole quantity, and the four operations can be regarded as all the equipment of mathematicians.

13, number theory is the oldest branch of human knowledge, but some of his deepest secrets are closely related to his most ordinary truth.

14, infinite, no other problem has touched the human mind so deeply.

15, this is a reliable law. When the author of mathematics or philosophy works writes with vague and abstruse words, he is talking nonsense.
