Youtube Video Lesson - The Five Platonic Solids - Basic Geometry

I have begun a YouTube video series on the five Platonic Solids.  In the first video, I describe the basic geometrical properties of the Platonic Solids.  We show how to define the Platonic Solids geometrically, observe their shapes and count their faces, edges, and vertices, and give a proof that these are the only five regular solids.


I also discuss the link to Plato and explain how Plato gave a correspondence to the elements in the dialogue Timaeus.  In future videos, I will go into much more depth on the mathematics of the Platonic Solids and describe meditation exercises with visualizing the solids.
