[math-fun] Draft of December 31 blog post
I've written something different for this month: a (mostly) tongue-in-cheek promotion for an upcoming mathematical holiday called "Thirdsday". (The holiday is bogus; the math is real.) You can read the current draft at http://mathenchant.org/043-share.pdf . Suggestions are welcome, especially suggestions for mathematically interesting occurrences of the number 1/3. (I'm saving "the volume of a pyramid is 1/3 times the area of the base times the height" and "the integral of x^2 from x=0 to x=1 is 1/3" for the next Thirdsday, just over a decade from now.)

Hah, delightful. I'll mention the lovely paper "Division by 3", by Peter Doyle and John Conway, https://math.dartmouth.edu/~doyle/docs/three/three.pdf. It's aimed at a dramatically different audience than the rest of your column, though, so not sure if you'll want to work it in. --Michael On Thu, Dec 27, 2018 at 8:07 PM James Propp <jamespropp@gmail.com> wrote:

Oops sorry, as Neil points out, that version doesn't have the figures. The arXiv version does, though: https://arxiv.org/abs/math/0605779 --Michael On Fri, Dec 28, 2018 at 12:41 PM Michael Kleber <michael.kleber@gmail.com> wrote:

Hi Jim - this is a lot of fun! I especially liked My daughter’s 7th-grade class enjoyed the fact that 10 * 0.3333 = 3.3333 = 3 + 0.3333 or (vulgarly) 10 = 3 + 1/3 or the abomination 10 = 3 1/3 I did this as a warm up for summing geometric series. - Cris
