TED stands for Technology, Entertainment and Design. This is a nonprofit group that organisers inspirational expert speakers from a variety of fields and then invites a coupe of hundred colleagues to listen to cutting edge ideas or theories. These videos or podcasts can then be downloaded to your MP3 or iPod. I love the convenience of listening to these when I want.
The organisers of TED included the following quote on their website to give an insight into their reasoning.
"We believe passionately in the power of ideas to change attitudes, lives and ultimately, the world. So we're building here a clearinghouse that offers free knowledge and inspiration from the world's most inspired thinkers, and also a community of curious souls to engage with ideas and each other."
There are dozens of talks that are both fascinating and thought provoking. This site is well worth a visit.
