NPR: TED Radio Hour

We often forget to say the words "thank you." But can those two words change how you — and those around you — look at the world? This hour, TED speakers on the power of gratitude and appreciation. Guests include author AJ Jacobs, author and former baseball player Mike Robbins, Dr. Laura Trice, Professor of Management Christine Porath, and former Danish politician Özlem Cekic.

Original broadcast date: May 12, 2017. When loss, violence, or betrayal test our willingness to forgive — how do we do it anyway? This hour, TED speakers explore the challenges and benefits of forgiving others — and ourselves. Guests include mental health advocate Sue Klebold, co-authors Thordis Elva and Tom Stranger, and writer Elizabeth Lesser.

Original broadcast date: March 7, 2014. In this hour, TED speakers question whether we can experience the world more deeply by not only extending our senses — but going beyond them. Guests include artist Neil Harbisson, engineer Todd Kuiken, speech scientist Rupal Patel, and sound expert Julian Treasure.

Are we simply the sum of our experiences? Or can we choose our own path? In this hour, TED speakers share stories of undergoing remarkable transformations despite extraordinary challenges. In a special updated interview, biophysicist Hugh Herr explains that in the coming decades, wearable robotics will allow humans to augment their physical capabilities. Other guests from the original 2014 episode include peace advocate Zak Ibrahim, model Geena Rocero, and criminal justice reform advocate Shaka Sengor.

Colonizing Mars or more distant planets seems like science fiction. But becoming a spacefaring species may be in our near future. This hour, TED speakers on living beyond Earth--and whether we should. Guests include NASA Chief Scientist James Green, science writer Stephen Petranek, MIT Media Lab researcher Lisa Nip, and astronomer Lucianne Walkowicz.
