Yes, My Mommy’s on YouTube

Most of my readers are aware that my mother, Karen of the previously mentioned Karen’s Devotions, was a homeschooling parent. Fewer know that before, during, and after that, she also has been a Math lecturer at a local state university. Her specialty lies in fractal geometry, and one of her longtime hobbies has been the Japanese paper-folding art of origami. Last Saturday, at a teaching conference, she presented on “The Hyperbolic Paraboloid: Exploring the Mystery,” serving her audience popcorn and Pringles to illustrate real-world saddle shapes. Her supplemental video “Origami Hyperbolic Paraboloid” shows how the viewer can create the rarely discussed 3-D truncated version. Take a look!
