Hi samoasilk,
This is a nice choice of topic, and you made a pretty fair attempt at it. But I would like to give you some pieces of advice to keep handy with, so as to create a more quality STEM post.

• First of all, it is always a good practice to include "reference for further reading" in your posts.
• Also, try to use only images from copyright-free sites. Some of the images you used aren't. Though some are; by inference; grouped under public domain upon the demise of the author - like the images of Pythagoras, etc, which you can use freely. You can refer to this guideline on image sourcing.

Cheers and thanks
