Can art save lives? Not exactly, but our most prized professionals (doctors, nurses, police officers) can learn real world skills through art analysis. Studying art like René Magritte's Time Transfixed can enhance communication and analytical skills, with an emphasis on both the seen and unseen. Amy E. Herman explains why art historical training can prepare you for real world investigation.

Lesson by Amy E. Herman, animation by Flaming Medusa Studios Inc.

In this well-argued talk, Timothy Bartik makes the macro-economic case for preschool education -- and explains why you should be happy to invest in it, even if you don't have kids that age (or kids at all). The economic benefits of well-educated kids, it turns out, go well beyond the altruistic. (Filmed at TEDxMiamiUniversity.)

Imagine you're a shipwrecked sailor adrift in the enormous Pacific. You can choose one of three directions and save yourself and your shipmates -- but each choice comes with a fearful consequence too. How do you choose? In telling the story of the whaleship Essex, novelist Karen Thompson Walker shows how fear propels imagination, as it forces us to imagine the possible futures and how to cope with them.

Talk by Karen Thompson Walker.

On the coast of Northern Ireland, a vast plateau of basalt slabs and columns called the Giant’s Causeway stretches into the ocean. The scientific explanation for this is that it’s the result of molten lava contracting and fracturing as it cooled in the wake of a volcanic eruption. But an ancient Irish myth has a different accounting. Iseult Gillespie recounts the Giant's Causeway myth.

Lesson by Iseult Gillespie, animation by Dylan Glynn.

In the 1600s, the Dutch East India Company employed hundreds of ships to trade goods around the globe. In order to fund their voyages, the company turned to private citizens to invest money to support trips in exchange for a share of the profits. In doing so, they unknowingly invented the world’s first stock market. So how do companies and investors use the market today? Oliver Elfenbaum explains.

Lesson by Oliver Elfenbaum, directed by Tom Gran and Madeleine Grossi.

Travel into the brain to see what happens when you fall in love and explore how the brain responds to heartbreak.

--

Love is often described as heartwarming, heart-wrenching, or even heartbreaking— and your brain is responsible for all these feelings. The journey from first spark to the last tear is guided by a symphony of neurochemicals and brain systems. Shannon Odell explores what happens in your brain when you fall in love, how it responds to a relationship, and how it reacts to a breakup.

Lesson by Shannon Odell, directed by Biljana Labović.
