The TED conference’s legendarily addictive TED talks are presentations that feel like an education. TED-Ed is education that feels like a TED Talk. Hosting lively YouTube-based lessons drawn from TED talks, created by invited educators, illustrated by animators and submitted by the TED community, the site tackles topics from “The dawn of art” to “The basics of boson.” Multiple-choice quizzes and essay questions let you prove you were paying attention.
