I know that this video is old, but I was cruising through YouTube this morning and I came across it again. It’s James Randi’s TED presentation from 2010, and it’s wonderful. It’s a basic primer on Randi’s brand of skepticism and is a lot of fun….it even has one of my favorite bits: Randi ingests an entire bottle of homeopathic sleeping pills demonstrates their inefficacy. Anyway, if you’ve never seen it, enjoy! It’s fun stuff.
