TED Radio Hour on WBAA News

Saturdays at 3 p.m.
  • Hosted by Guy Raz

TED Radio Hour is a journey through fascinating ideas, astonishing inventions and new ways to think and create. Each episode includes riveting excerpts from the renowned TED stage where some of the world's deepest thinkers and innovators are invited to give the 18-minute "talk of their lives." The TED Radio Hour team takes the most compelling talks and organizes them around a common theme. But we don't stop with the TEDTalks. Host Guy Raz interviews the guests, delving deeper, dissecting the speaker's ideas and posing probing questions you’d like to hear answered.

Topics the series explores include mankind's place in the universe and space, how the sounds around us affect our behavior and why there is power in failure.
