After taking part in the discussion in preparation of the presentation for the course “British History and Classical Texts”, I was on the way to Walmart for cheeses, when I suddenly discovered I took no money with me. While with the new decision to simply ride downtown, I actually ended up arriving at the MIXC (万象城) distant from the center. Since I had no money, I could do nothing but take photos…
I actually intended to park at the Xinhua bookstore on Qingchun road and have a look. However, I forgot that when I was regretting on not taking any money and not being able to buy cheeses. There is also a bookstore in MIXC though. It’s called Page One, and sells mostly petite bourgeoisie books, e.g. on interior design, cooking, literature, history and philosophy, many of which are in English.
The book From Calculus to Cohomology by Madsen looks a nice book. Well, it’s the first time I saw an introduction to topology from CALCULUS so I believe it amazing. Maybe I am too ignorant in mathematics.
I’m studying Commutative Algebra and Topology recently. As far as I’m concerned, categories are fundamental in mathematics so I’m particularly fond of algebra in favor of the concept of category. I saw some one says geometry and topology structures are much more interesting than algebra structures. I don’t understand it very much. Maybe in my mind all structures are algebraic. Well, maybe when we adopt measures and Cauchy sequences we are entering the field of Analysis, Geometry and Topology? Actually in my heart it is still algebraic. I think continuity doesn’t mean non-algebra. Continue reading “Diary (Sep 4, 2010)”
