What motivates us to work? Contrary to conventional wisdom, it isn't just money. But it's not exactly joy either. It seems that most of us thrive by making constant progress and feeling a sense of purpose. Behavioral economist Dan Ariely presents two eye-opening experiments that reveal our unexpected and nuanced attitudes toward meaning in our work.
Some of us learn best in the classroom, and some of us ... well, we don't. But we still love to learn, to find out new things about the world and challenge our minds. We just need to find the right place to do it, and the right community to learn with. In this charming talk, author John Green shares the world of learning he found in online video.

In the US, 80% of girls have been on a diet by the time they're 10 years old.

She suggests ideas for how to live a less diet-obsessed life, intuitively.

Right now, billions of neurons in your brain are working together to generate a conscious experience -- and not just any conscious experience, your experience of the world around you and of yourself within it. How does this happen? According to neuroscientist Anil Seth, we're all hallucinating all the time; when we agree about our hallucinations, we call it "reality." Join Seth for a delightfully disorienting talk that may leave you questioning the very nature of your existence.

A moving and inspiring account of loss, rebirth and renewal - and the discovery of 'a world beyond sight'. In 1983, after decades of steady deterioration, John Hull, a professor at the University of Birmingham, became totally blind. To help him make sense of the upheaval in his life, he began documenting his experiences on audio cassette. Over three years he recorded over sixteen hours of material. This beautifully crafted documentary takes John's original recordings as the template for the film, incorporating lip-syncing by actors in evocative reconstructions. The technique allows the viewer to immerse themselves in John's world as he comes to terms with his deteriorating sight, and learns to experience the world in different ways. As John explains about his redemptive journey: 'I knew that if I didn't understand blindness, it would destroy me.'
