I frequently recommend this site to students to learn how to develop and deliver outstanding presentations. The videos of these talks are certainly worthwhile for gaining tips on improving your “style”, but they are also some of the most fascinating talks I’ve ever heard. Here is a sprinkling of example topics:
“Medicine Without Borders” (43 talks)
“Numbers at Play” (17 talks)
“Tales of Invention” (132 talks)
“Design Like You Give a Damn” (54 talks)
“How the Mind Works” (73 talks)
“Evolution’s Genius” (57 talks)
“How We Learn” (51 talks)
Some of the scientists who have given TED talks will be familiar to you, but most will not. If you ever doubted that scientists could be fascinating speakers, however, this site will change your mind.
Warning: These talks are so entertaining, it’s easy to spend a great deal of time watching them.
