My school library just moved buildings and had to give away 70,000 books and they decided on mostly nonfiction and reference, so I adopted some.

I don’t honestly know when I’ll read them (except H2G2, which I’ve already read). I think I’d like to read the dictionary, it seems like such a quaint thing to do, and hardly anyone tries anymore. Maybe in my spare time ðŸ˜›

Just bought two intro books on topology from Amazon! Used, so super cheap ^â—¡^

The first was H. Graham Flegg’s From Geometry to Topology. According to Dover Publishing,

This excellent introduction to topology eases first-year math students and general readers into the subject by surveying its concepts in a descriptive and intuitive way, attempting to build a bridge from the familiar concepts of geometry to the formalized study of topology. The first three chapters focus on congruence classes defined by transformations in real Euclidean space. As the number of permitted transformations increases, these classes become larger, and their common topological properties become intuitively clear. Chapters 4â€“12 give a largely intuitive presentation of selected topics. In the remaining five chapters, the author moves to a more conventional presentation of continuity, sets, functions, metric spaces, and topological spaces. Exercises and Problems. 101 black-and-white illustrations. 1974 edition. (Link)

The second was B.H. Arnold’s *Intuitive Concepts in Elementary Topology. * According to Dover Publishing, it is

Classroom-tested and much-cited, this concise text offers a valuable and instructive introduction for undergraduates to the basic concepts of topology. It takes an intuitive rather than an axiomatic viewpoint, and can serve as a supplement as well as a primary text.

A few selected topics allow students to acquire a feeling for the types of results and the methods of proof in mathematics, including mathematical induction. Subsequent problems deal with networks and maps, provide practice in recognizing topological equivalence of figures, examine a proof of the Jordan curve theorem for the special case of a polygon, and introduce set theory. The concluding chapters examine transformations, connectedness, compactness, and completeness. The text is well illustrated with figures and diagrams. (Link)

I’m so excited!

I recently found a great website by Nathan Dunfield, who (among many other things!) runs the blog Low Dimensional Topology.Â The website, CompuTop.org, is a software archive, “a site for for people doing computational stuff with low-dimensional topology.”Â I stumbled on it looking for a download for SnapPy, but having found this entire list I think I’m going to try them all.
