"Yes homo!" I exclaim delightedly upon realizing that the Q(x) of my linear differential equation in standard form is equal to zero. After all, everyone loves to work with homogeneous equations.

How to interpret inverse functions.

"Pure mathematics consists entirely of such asseverations as that, if such and such a proposition is true of anything, then such and such another proposition is true of that thing… It’s essential not to discuss whether the proposition is really true, and not to mention what the anything is of which it is supposed to be true… If our hypothesis is about anything and not about some one or more particular things, then our deductions constitute mathematics. Thus mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true."

Bertrand Russell, quoted by J. A. Paulos in Beyond Numeracy (1992)

The answers to this question are pretty funny, and also fairly informative!

Howdy, everyone! Tonight we’re rolling out Mathemedia, a compendium of math-related media — and we’re looking for your submissions!
Send us your favorite books, movies, songs, art, essays, and articles (etc.) that prominently feature mathematics or mathematicians — and we’ll add them to Mathemedia. But first! a few ground rules:
We prefer that material be accessible to anyone with a love of mathematics and access to Wikipedia — assuming, at most, a typical high school education in math.
In general, we’re looking for stories about mathematics — told either from the inside or outside. Fiction is great; non-fiction is good too, as long as it’s designed for more than a mathematically-trained audience. There are several great lists out there on the interwebs of seminal papers and great textbooks and phenomenal websites — this is not one of them.
If you have the time, please include a short description of the book, movie, etc. in question. This will help anyone browsing the list figure out what’s most interesting and appealing to them. If the material is legally available on the Internet (e.g., an article or music video), feel free to include a link!
Thanks for helping spread our love of math! We’ll start putting up what you submit later tonight.
This list was inspired by math-is-beautiful's fabulous list of math-related blogs :)

Updated (finally)! Take a look and let us know if we’re missing anything!
