I finished the article on Pythagoras to Rich Theory. I did the orginal research on this work some 20 years ago; so I am going through books and online sources to verify things. It is long and tedious.
I admit, I am having a much harder time than I thought I would. Terminology in mathematics keeps changing. Of course, I am actually trying to make a point that terminology changes. The Pythagoreans did most of their mathematics drawing in sand or with rocks. Instead of dividing by two, they would have spoken of evenness balancing eveness. Anyway, I stayed up too late. I will put the section through a final edit tomorrow.
