I came across this website just recently and thought it was worth sharing with any community of thoughtful people.
www.ted.com is a collection of brief lectures (between 5 and 10 minutes) on topics ranging from environmentally friendly construction to evolution. Each themed section presents a pretty eclectic selection of presenters, like this section on ‘How the Mind Works’, which contains lectures from Daniel Dennet, Stephen Pinker, Philip Zimbardo, and even the current first lady. Though the lectures may be short and simple, they do provide a certain kind of intellectual entertainment that isn’t always easy to find. Enjoy!
