This link takes you to a good video/documentary about Non - Euclidean geometry;


  • Did you watch this video? If you did, please comment here about how it connects to what we did in class. Ethan

The video is from 1988 but it narrates about the hardship Euclid, Lobachevsky among others, had to go through as they revealed their new ideas to the world. But the most interesting part, it's how they decided to present the ideas ( i.e postulates). The illustration is the most interesting part. They use a globe (sphere), and my other pictures to give a really good explanation. It adds to what we learned in class by presenting old ways to describe geometry ( pen and paper) instead of what we are used to use today, technology.
