# About The Level of Math I want to make normal people understand even if I write on a very difficult topic. Also, I don't want to write sequentially so that you don't have to read all the previous posts to understand recent posts. However, a bad thing happened. Yesterday, I wrote about prime idea ls and affine varieties without any explain. I think normal people can easily understand affine varieties if they are willing to, but I don't think they can understand what the hell prime ideals are. The post itself is OK, because it is more about algebra-geometry c orrespondence. The problem is, suppose I write about prime ideals so that they ca n understand. I'll certainly write about the spectrum of a ring to o. Then next day, I might write about schemes. To explain a scheme , I have to write about a sheaf and the underlying topology. If I proceed this, I might eventually end up explaining algebraic stack s, topoi, and even motives. OK, I know that's a slippery slope argument, and is a logical fall acy. I don't think I will actually end up explaining motives, even if I explain the spectrum of a ring. But when it comes to the lev el of math, I think I'm not that wrong. So, how can I find the optimal level, and keep it indefinitely? Th at's the problem.
