The TED Idea Search wraps up in Amman, Jordan, in a 2,000-year-old Roman amphitheater and in front of a crowd of 4,000. What unfolds inside those stone walls is something the series hasn't quite seen before: speakers shaped by the weight of living in a region the world tends to define for itself. From a mountaineer who turned grief into motivation to a therapist rewriting the Arab world's language around mental health, the final city makes the strongest case yet that the best ideas can come from anywhere.
