It suddenly occurred to me that when we were primary and secondary school students, mathematics was very easy. In college, mathematics began to become difficult. Is math really getting harder and harder? Or is it because our understanding of the world is getting more and more comprehensive, forming a stereotype in our minds, and our thinking can only be carried out on the basis of the world in impression, and many of the world in impression that we have come into contact with do not need mathematics, and all this in life is too familiar, even high school mathematics is rarely used, let alone advanced mathematics?
So far, I have come to two conclusions:
1, more mathematics should be used in the world outlook to strengthen the connection with real life;
2. Even if our three views are becoming more and more complete and tend to form a stable system, we have to admit that there are still many things that we can't touch, and there are still many things that we can only control. Mathematics comes from the real world, and we must be more modest about this world in order to accept mathematics better.
