Legendary architect Renzo Piano -- the mind behind such indelible buildings as The Shard in London, the Centre Pompidou in Paris and the new Whitney Museum of Art in New York City -- takes us on a stunning tour through his life's work. With the aid of gorgeous imagery, Piano makes an eloquent case for architecture as the answer to our dreams, aspirations and desire for beauty. "Universal beauty is one of the few things that can change the world," he says. "This beauty will save the world. One person at a time, but it will do it."

Multidisciplinary artist and TED Fellow Paul Rucker is unstitching the legacy of systemic racism in the United States. A collector of artifacts connected to the history of slavery -- from branding irons and shackles to postcards depicting lynchings -- Rucker couldn't find an undamaged Ku Klux Klan robe for his collection, so he began making his own. The result: striking garments in non-traditional fabrics like kente cloth, camouflage and silk that confront the normalization of systemic racism in the US. "If we as a people collectively look at these objects and realize that they are part of our history, we can find a way to where they have no more power over us," Rucker says. (This talk contains graphic images.)

Truth comes from the collision of different ideas, and theater plays an essential role in showing us that truth, says legendary artistic director Oskar Eustis. In this powerful talk, Eustis outlines his plan to reach (and listen to) people in places across the US where the theater, like many other institutions, has turned its back -- like the deindustrialized Rust Belt. "Our job is to try to hold up a vision to America that shows not only who all of us are individually, but that welds us back into the commonality that we need to be," Eustis says. "That's what the theater is supposed to do."
