As all parents know, no two slices of cake are exactly the same. In the eyes of children, their piece is always smaller than the others’ pieces, which triggers the inevitable cry of “It’s not fair!” Evaluating the actual size of the slice is one of our first failed experiments in our assessment of proportions, something that will never change. Just like our irresistible fascination with all things circular. That’s why a chapter on pies and donuts is mainly an exercise in damage control.
