I have seen a lot of talks from TED online, & been interested in the variety of subjects covered. The other day I actually checked out their website, subtitled "Ideas worth spreading". Hear talks on joint replacement, fractals, global population, & more! On-site ratings include jaw-dropping, informative, funny, & beautiful. Here are a couple examples of what you'll find there:
J.K. Rowling: The Fringe Benefits of Failure (2008 Harvard Commencement speech)
At her Harvard commencement speech, "Harry Potter" author JK Rowling offers some powerful, heartening advice to dreamers and overachievers, including one hard-won lesson that she deems "worth more than any qualification I ever earned."
Elizabeth Gilbert on nurturing creativity
Isabel Allende tells tales of passion
Doris Kearns Goodwin on learning from past presidents
