I can talk about my thoughts. At present, the development of mathematics has never reached the bottleneck. After all, there is no end to learning. There must be more mathematical theorems and mysteries waiting for us to develop. The impetus of mathematics to the development of modern science must be unshakable, because basically all scientific theories are inseparable from mathematics, astronomy, geography, physical chemistry, biology, geology, meteorology and so on. , including mobile phones and computers used in daily life, are all developed on the basis of mathematics. If there is no mathematics, then all science can't develop. As far as the current development of mathematics is concerned, I feel that I am only in adolescence, and there must be more room for development. This is an extraordinary mathematical problem. It feels more like a brain teaser than a pure math test. If the IQ is high enough, even people with low mathematical attainments can answer it. Finally, I think it should be no problem for China to rank among the top five in mathematics in the world. After all, China's heavy industry is still relatively strong, such as nuclear weapons, manned space flight and even landing on the moon, which are among the top three in the world. Countries that can do these things are definitely among the best in mathematics.
