Sure is quiet around here. I can't blog much, as I'm in the final throes of book-writing. So instead, let's have some user-generated content! Here is a figure that I've drawn for use in my book.
Your mission, should you choose to accept it, is to figure out what the figure is supposed to be illustrating, and what lesson is purportedly conveyed. (Hint: that's supposed to be an egg.) How hard can it be? If it's a fruitful exercise, we can repeat for other figures, similarly inscrutable.
