Artist Titus Kaphar makes paintings and sculptures that wrestle with the struggles of the past while speaking to the diversity and advances of the present. In an unforgettable live workshop, Kaphar takes a brush full of white paint to a replica of a 17th-century Frans Hals painting, obscuring parts of the composition and bringing its hidden story into view. There's a narrative coded in art like this, Kaphar says. What happens when we shift our focus and confront unspoken truths?

Loneliness doesn't always stem from being alone. For architect Grace Kim, loneliness is a function of how socially connected we feel to the people around us -- and it's often the result of the homes we live in. She shares an age-old antidote to isolation: cohousing, a way of living where people choose to share space with their neighbors, get to know them, and look after them. Rethink your home and how you live in it with this eye-opening talk.

Sinéad Burke is acutely aware of details that are practically invisible to many of us. At 105 centimeters (or 3' 5") tall, the designed world -- from the height of a lock to the range of available shoe sizes -- often inhibits her ability to do things for herself. Here she tells us what it's like to navigate the world as a little person and asks: "Who are we not designing for?"

A few days before she turned 61, writer Anne Lamott decided to write down everything she knew for sure. She dives into the nuances of being a human who lives in a confusing, beautiful, emotional world, offering her characteristic life-affirming wisdom and humor on family, writing, the meaning of God, death and more.

There's a creepy transformation taking over our cities, says architecture critic Justin Davidson. From Houston, Texas to Guangzhou, China, shiny towers of concrete and steel covered with glass are cropping up like an invasive species. Rethink your city's anatomy as Davidson explains how the exteriors of building shape the urban experience -- and what we lose when architects stop using the full range of available materials.

One night in 2002, a friend gave Jorge Drexler the chorus to a song and challenged him to write the rest of it using a complex, poetic form known as the "Décima." In this fascinating talk, Drexler examines the blended nature of identity, weaving together the history of the Décima with his own quest to write one. He closes the talk with a performance of the resulting song, "La Milonga del Moro Judío." (In Spanish with English subtitles)

To design the Bahá'í Temple of South America, architect Siamak Hariri focused on illumination -- from the temple's form, which captures the movement of the sun throughout the day, to the iridescent, luminous stone and glass used to construct it. Join Hariri for a journey through the creative process, as he explores what makes for a sacred experience in a secular world.

Emtithal "Emi" Mahmoud escribe poesía de resistencia, enfrentando en verso su experiencia al escapar del genocidio en Darfur. Ella nos comparte dos emotivos poemas originales sobre los refugiados, la familia, la alegría y la tristeza, y nos pregunta: "¿Serían mis testigos?".

How much energy and brain power do we devote to learning how to spell? Language evolves over time, and with it the way we spell -- is it worth it to spend so much time memorizing rules that are filled with endless exceptions? Literary scholar Karina Galperin suggests that it may be time for an update in the way we think about and record language. (In Spanish with English subtitles)

John Koenig loves finding words that express our unarticulated feelings -- like "lachesism," the hunger for disaster, and "sonder," the realization that everyone else's lives are as complex and unknowable as our own. Here, he meditates on the meaning we assign to words and how these meanings latch onto us.
