‘TED' stands for Technology, Entertainment and Design. It's a conference format that started in California in 1984 as a platform for the interdisciplinary exchange of ideas. The 18-minute talks are by far the most fascinating conference talks you'll ever see, partly because speakers know they'll be watched by millions of people online. A TEDx is an independently organized conference that shares TED values, quality and format at the local level. We asked organizer Felix Vannucci about TEDx Florence, which takes place on November 12, 2011.
