This hour, TED speakers explore how this force can be dialed up or down to improve our lives. Guests include tribologist Jennifer Vail, democracy activist and whistleblower Yaël Eisenstat, Sierra Leone's Minister of Education David Moinina Sengeh and TV producer Elan Gale. Original broadcast date: October 7, 2022.
