wiki:
In mathematics, singularity theory studies spaces that are almost manifolds, but not quite. A string can serve as an example of a one-dimensional manifold, if one neglects its thickness. A singularity can be made by balling it up, dropping it on the floor, and flattening it.
lol, awesome

why need endless time? do you read novels in your spare time? think of it as one of those!
― flopson, Friday, 20 January 2017 16:35 (nine years ago)
maybe you can read math books at the same speed as you do novels, not me
― Guayaquil (eephus!), Friday, 20 January 2017 16:36 (nine years ago)
why does it have to be at the same speed?

at one point in my life I had the habit of reading a page of Hilbert's Geometry and the Imagination a day. I never finished it but it doesn't matter; it was a blast

Is there in iPhone app that I can use to solve or graph or factor algebraic equations? Basically do what my old TI-89 could do back in my high school days, (except in color obv.)?

Mr. Snurb, Wolfram Alpha is useful. It even has an iPhone app. In addition to factoring, it can be used to integrate or even solve mildly complicated PDE/sODEs. The syntax, IMO, is much nicer than a calculator you can use natural language or TeX-like formatting.

does anybody know the line elements in 4D hyperspherical coordinates or how to go about deriving them? i need to know for a school project and didn't realize this information would be so hard to find lol
