I am a science student, to be precise, a doctoral candidate (currently studying) in basic mathematics. Over the years I've learned a lot of cool math and heard a lot of interesting gossip. Why don't I just share it here? It's a pity that Latex can't be used as the starting point, so I can only try to reduce the formulas as much as possible.
I haven't decided what I want to write about yet (of course, it will definitely be related to mathematics). Maybe it will just popularize some small concepts and tell some short stories. The words "Just a few words" should be able to sum up my attitude of letting it go, haha. Maybe I will just write some fragments similar to a diary, maybe I will write an organized chapter, in short, whatever makes me happy.
In the first part, I plan to write a series of re-reading textbooks. The great F. Klein wrote "Elementary Mathematics from a High Point of View", which is a masterpiece handed down from generation to generation. I am just a beginner. I don't have the ability to organize my own structure, so I can only rely on the existing textbook table of contents to organize the framework and say some nonsense similar to complaints. F. Klein's high views are really high views, but elementary mathematics is not that elementary mathematics. I wrote "Elementary Mathematics from a Low Viewpoint" to ensure that the viewpoint is very low and that it is elementary mathematics!
Note: I try to use foreign languages for the names of people and places. Some professional terms will also be used in English because there is no recognized translation. Thinking about it, Mr. Li WW and Mr. Li JH insist on writing mathematics textbooks in Chinese. They are really two great people!
Purpose: Record the knowledge I learned
