A simple puzzle that leads to a transcendental equation: I'm going to cut a circular cookie into thirds (3 equal areas) by making two vertical cuts. Where should they be made? (I learned this from Gosper, but it must predate the invention of trigonometry. Probably just after cookies were invented.) A 3D version: The density of ice is .9, water is 1. A spherical iceberg of diameter 1 is floating in the ocean. How high is the tip of the iceberg over the surface of the water? Rich rcs@cs.arizona.edu
