Is Two Big Enough?

Micah Fogel 

March 2003

Abstract:

Whether the book is faceup or facedown tells you something about the number of times you have turned it over. If the book is faceup, you must have turned it upside down and rightside up the same number of times. If the book is facedown, you must have turned it upside down one extra time. A word that captures this idea is parity. Parity is a very simple concept, it also is very powerful.
