TED Talks have become some of the mostly highly-coveted tickets in the world in the 30 years since the conferences started as a four-day event in California. Twice a year, the world’s most important thinkers take the stage to discuss the issues of the world and how we will face our future. Past speakers at TED have included Bill Gates, Sir Richard Branson, Jane Goodall, Elizabeth Gilbert, and many more. In the spirit of TED, independent events called TEDx have sprouted up across the country, including one tonight, August 29th, in Kansas City, at which Chaz Ebert will be one of the speakers. Other speakers this year include Tommy Caldwell, Dara Dotz, Scott Hamilton and Dr. Barmak Heshmat. You can learn more about the event here and watch the trailer below.
