Few sensations feel better than when your mind does a backflip and, all of a sudden, you are suddenly able to see things in new and unexpected ways. At TEDGlobal 2013, themed “Think Again,” you’ll have this feeling often. “The approach we adopted,” explains TEDGlobal curator Bruno Giussani, “is to take a closer look at the global remix happening before our eyes as power shifts, culture and technology intersect, and hopes and anxieties collide. Many things we think we know may have to be reconsidered — and that’s what this program is designed to explore.” With speakers including biologists, economists, neuroscientists, architects, technologists, activists, artists, a “gentleman thief” and the former Prime Minister of Greece, the program is packed with speakers who take bold new looks at the topics that most intrigue us.

TEDGlobal 2013 will take place June 10 to 14, 2013, in Edinburgh, Scotland — one of the world’s best-preserved medieval cities. The conference is also watchable all across the globe with a TED Live membership. Here, the list of this year’s incredible speakers and performers.
