Celebrating the Season With a Tribute and Some Geometry

Pat Ballew 'celebrates the season' this morning with some "beautiful geometry" from "a little known mathematical dilettante":

Pat writes that George Odom Jr. "found five different simple geometrical approaches to the golden ratio using equilateral triangles, and platonic solids" that "are too beautiful to be so unknown." A nice tribute to someone likely unknown to most of us.

Also, a wonderful, 2007 piece by Siobhan Roberts (...you may have heard of her) on Odom, and his connection to John Conway, here:
