MathMonks?

[petemar1]

Has anyone found an analogue to Perl Monks but for mathematics instead of Perl?

PlanetMath. They have a very interesting engine - noosphere, with features similar to wiki but with a stronger authorship and with TeX rendering.

I have not seen any web logs/forums/communities specialized for mathematics outside of some K-12 sites. I think such a site could be fun and informative, if it was not buried in homework questions.

There are active forums on Usenet:

• alt.math.recreational (occasional fun posts + much spam)
• sci.math
• sci.stat.math
• sci.math.num-analysis
• sci.math.research (moderated)

These are not nearly as nice as Perlmonks, but interesting topics get discussed and people can sometimes get answers to questions.

Any good IRC channels, particularly for recreational math?

[jrtayloriv]

As far as math IRC, the #math channel on Freenode is very active, and is populated by several knowledgeable people at any given time.

(sorry to resurrect a dead thread, but I just wanted this up for anyone searching for this answer in the future)

It's not a peer-to-peer site like PM, but whenever I want to look up anything mathematical, I go to the various sites hosted at Wolfram.com

There is an excellant Math/Physics forum on the ISCA BBS at the University of Iowa. It's not HTML-based, but you can telnet in and read forums as a guest or set up an account to post to (almost) any of the forums. I used it a bit when I was taking my fourth year of Physics in college and there seemed to be plenty of folks with answers/explanations to almost every problem for both Math and Physics.

I like the TeX rendering feature. I can just imagine a flux integral through a eigth-dimensional hypersolid, all perfectly rendered in ASCII with pre tags!

* = if this doesn't make any sense, well, either I forgot my Calculus III course due to lack of use or I intentionally blocked it out... no...wait... BOTH!

[ambrus]

What? Multi-dimensional integrals and Fubini-theorem and thesuch is Calculus II (at least here).

[jryan]

I think whether or not you cover this kind of stuff in "Calculus II" or "Calculus III" is dependant on whether your school is on quarters or semesters.
