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.

We’ve heard that bees are disappearing. But what is making bee colonies so vulnerable? Photographer Anand Varma raised bees in his backyard — in front of a camera — to get an up close view. This project, for National Geographic, gives a lyrical glimpse into a bee hive — and reveals one of the biggest threats to its health, a mite that preys on baby bees in the first 21 days of life.

In the US, 80% of girls have been on a diet by the time they're 10 years old. In this honest, raw talk, neuroscientist Sandra Aamodt uses her personal story to frame an important lesson about how our brains manage our bodies, as she explores the science behind why dieting not only doesn't work, but is likely to do more harm than good. 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.

Louis XIV the Sun King had France's magnificent Palace of Versailles built and it pays extraordinary testimony to his reign. He ruled for an incredible 72 years at a time when France was all powerful. Discover the truth about the King's very open 'secret' second marriage to Francois D'Aubinge and his many affairs. It’s been claimed Louis bathed only three times in his entire life. How does that square with the luxurious Turkish bath at the Palace, or the stories of him disinfecting his skin with alcohol, or the fact that he had literally hundreds of pairs of underwear which he changed many times during a day? He was very conscious of his height at only five feet four inches tall, however in his wigs and heels he appeared to be alot taller, Tracy explains how this extraordinary effect was achieved.
Man on Wire is a 2008 documentary film directed by James Marsh. The film chronicles Philippe Petit's 1974 high-wire walk between the Twin Towers of New York's World Trade Center and is based on Philippe Petit's book, To Reach the Clouds, which has recently been released in paperback with the new title Man on Wire. The film is crafted like a heist film, presenting rare footage of the preparations for the event and still photographs of the walk, alongside reenactments (with Paul McGill as the young Petit) and modern-day interviews with the participants. Native New Yorkers know to expect the unexpected, but who among them could've predicted that a man would stroll between the towers of the World Trade Center? French high-wire walker Philippe Petit did just that on August 7th, 1974. Petit’s success may come as a foregone conclusion, but British filmmaker James Marsh’s pulse-pounding documentary still plays more like a thriller than a non-fiction entry--in fact, it puts most thrillers to shame. Marsh (Wisconsin Death Trip, The King) starts by looking at Petit's previous stunts. First, he took on Paris's Notre Dame Cathedral, then Sydney's Harbour Bridge before honing in on the not-yet-completed WTC. The planning took years, and the prescient Petit filmed his meetings with accomplices in France and America. Marsh smoothly integrates this material with stylized re-enactments and new interviews in which participants emerge from the shadows as if to reveal deep, dark secrets which, in a way, they do, since Petit's plan was illegal, "but not wicked or mean." The director documents every step they took to circumvent security, protocol, and physics as if re-creating a classic Jules Dassin or Jean-Pierre Melville caper. Though still photographs capture the feat rather than video, the resulting images will surely blow as many minds now as they did in the 1970s when splashed all over the media. Not only did Petit walk, he danced and even lay down on the cable strung between the skyscrapers. It competed in the World Cinema Documentary Competition at the 2008 Sundance Film Festival, where it won the Grand Jury Prize: World Cinema Documentary and the World Cinema Audience Award: Documentary. In February 2009, the film won the BAFTA for Outstanding British Film, the Independent Spirit Awards and the Academy Award for Best Documentary.

Alice Roberts explores the latest discoveries in the study of human origins, revealing the transformation that has been brought about in this field by genetics. Traditional paleo-anthropology, based on fossils, is being transformed by advanced genome sequencing techniques. We now know that there were at least four other distinct species of human on the planet at the same time as us - some of them identified from astonishingly well-preserved DNA extracted from 50,000-year-old bones, others hinted at by archaic sections of DNA hidden in our modern genome. What's more, we now know that our ancestors met and interacted with these other humans, in ways that still have ramifications today. Alice uses these revelations to update our picture of the human family tree.
