TED is a small nonprofit devoted to Ideas Worth Spreading. It started out (in 1984) as a conference bringing together people from three worlds: Technology, Entertainment, Design. Since then its scope has become ever broader. Along with the annual TED Conference in Long Beach, California, and the TEDGlobal conference in Oxford UK, TED includes the award-winning TEDTalks video site, the Open Translation Program, the new TEDx community program, this year’s TEDIndia Conference and the annual TED Prize.

Here is the list of some of my favorite TED presentations, but there are just so many inspiring presentations:

Joshua Prince-Ramus believes that if architects re-engineer their design process, the results can be spectacular. Speaking at TEDxSMU, Dallas, he walks us through his fantastic re-creation of the local Wyly Theater as a giant “theatrical machine” that reconfigures itself at the touch of a button.

At TED2009, Al Gore presents updated slides from around the globe to make the case that worrying climate trends are even worse than scientists predicted, and to make clear his stance on “clean coal.”

At TEDIndia, Pranav Mistry demos several tools that help the physical world interact with the world of data — including a deep look at his SixthSense device and a new, paradigm-shifting paper “laptop.” In an onstage Q&A, Mistry says he’ll open-source the software behind SixthSense, to open its possibilities to all.

We’re at a unique moment in history, says UK Prime Minister Gordon Brown: we can use today’s interconnectedness to develop our shared global ethic — and work together to confront the challenges of poverty, security, climate change and the economy.

Can the interests of an individual nation be reconciled with humanity’s greater good? Can a patriotic, nationally elected politician really give people in other countries equal consideration? Following his TEDTalk calling for a global ethic, UK Prime Minister Gordon Brown fields questions from TED Curator Chris Anderson.

You’ve never seen data presented like this. With the drama and urgency of a sportscaster, statistics guru Hans Rosling debunks myths about the so-called “developing world.”

20 years ago, Tim Berners-Lee invented the World Wide Web. For his next project, he’s building a web for open, linked data that could do for numbers what the Web did for words, pictures, video: unlock our data and reframe the way we use it together.
