2. God created integers, and all other numbers are man-made. ——L. Kronecker

3. Every new group discovered is mathematical in form because we can have no other guidance. ——Darwin

4. Pure mathematics is the magician’s real magic wand. ——Novales

5. Mathematics is an infinite science. ——Hermann Weyl

6. Mathematics has made an important contribution to the observation of nature. It explains the simple primitive elements in the regular structure, and the celestial bodies are built with these primitive elements. ——Kepler

7. Some beautiful theorems in mathematics have this characteristic: they are easily summarized from the facts, but the proofs are extremely hidden. ——Gauss

8. The incomparable permanence and omnipotence of mathematics and its independence from time and cultural background are direct consequences of its essence. ——Ebo

9. Questions are the heart of mathematics. ——P.R. Halmos

11. The first is mathematics, the second is mathematics, and the third is mathematics. ——Roentgen

12. No question can touch people's emotions as deeply as infinity. There are few other concepts that can stimulate the mind to produce fruitful thoughts like infinity. However, there is no other concept. The concept of infinity needs to be clarified. ——Hilbert

13. After modern high-energy physics reaches quantum physics, many experiments cannot be done at all. You can do calculations at home with pen and paper, which is not much different from what mathematicians think. Far, so mathematics has incredible power in physics. ——Qiu Chengtong

14. No question can touch people's emotions as deeply as infinity. There are few other concepts that can stimulate the mind to produce fruitful thoughts like infinity. However, there is no other The concept of can be as demanding of elucidation as infinity. ―Hilbert

17. The main goal of mathematics is the public interest and the explanation of natural phenomena. ——Fourier

18. The universe is huge, the particles are tiny, the speed of rockets, the ingenuity of chemical engineering, the changes in the earth, the mysteries of biology, and the complexity of daily life. Mathematics is used everywhere. ——Hua Luogeng

19. Observation may lead to discovery, and observation will reveal certain rules, patterns or laws. ——Polya

20. What delights me most in mathematics are those things that can be proven. ——Russell
