## MathWorld

Wednesday 10 August 2005 at 11:47 pm | In Articles | 4 CommentsMathWorld is a wonderful mathematics resource that is well worth browsing. It’s nice to see it has a sense of humour too – see 2001 A Space Odyssey and 42.

Does anybody know of other similar humorous entries at MathWorld or at other such resources such as PlanetMath or the maths pages of Wikipedia?
