TED Talks

Every seven years, designer Stefan Sagmeister closes his New York studio for a yearlong sabbatical to rejuvenate and refresh their creative outlook. He explains the often overlooked value of time off and shows the innovative projects inspired by his time in Bali. TEDGlobal 2009

In this short, optimistic talk from TED2009, Pete Alcorn shares a vision of the world of two centuries from now -- when declining populations and growing opportunity prove Malthus was wrong.

Information designer Tom Wujec talks through three areas of the brain that help us understand words, images, feelings, connections. In this short talk from TEDU, he asks: How can we best engage our brains to help us better understand big ideas?

In this short talk from TED U 2009, Brian Cox shares what's new with the CERN supercollider. He covers the repairs now underway and what the future holds for the largest science experiment ever attempted.

Neurologist and author Oliver Sacks brings our attention to Charles Bonnet syndrome -- when visually impaired people experience lucid hallucinations. He describes the experiences of his patients in heartwarming detail and walks us through the biology of this under-reported phenomenon

Why are babies cute? Why is cake sweet? Philosopher Dan Dennett has answers you wouldn't expect, as he shares evolution's counterintuitive reasoning on cute, sweet and sexy things (plus a new theory from Matthew Hurley on why jokes are funny).

Carolyn Porco shares exciting new findings from the Cassini spacecraft's recent sweep of one of Saturn's moons, Enceladus. Samples gathered from the moon's icy geysers hint that an ocean under its surface could harbor life.

Behavioral economist Dan Ariely studies the bugs in our moral code: the hidden reasons we think it's OK to cheat or steal (sometimes). Clever studies help make his point that we're predictably irrational -- and can be influenced in ways we can't grasp.

Extreme runner Ray Zahab shares an enthusiastic account of his record-breaking trek on foot to the South Pole -- a 33-day sprint through the snow.

Louise Fresco shows us why we should celebrate mass-produced, supermarket-style white bread. She says environmentally sound mass production will feed the world, yet leave a role for small bakeries and traditional methods.

At his carpet company, Ray Anderson has increased sales and doubled profits while turning the traditional "take / make / waste" industrial system on its head. In a gentle, understated way, he shares a powerful vision for sustainable commerce.

In this brief talk from TED U 2009, Jonathan Drori encourages us to save biodiversity -- one seed at a time. Reminding us that plants support human life, he shares the vision of the Millennium Seed Bank, which has stored over 3 billion seeds to date from dwindling yet essential plant species.

Jay Walker explains why two billion people around the world are trying to learn English. He shares photos and spine-tingling audio of Chinese students rehearsing English — "the world's second language" — by the thousands.

"Bonk" author Mary Roach delves into obscure scientific research, some of it centuries old, to make 10 surprising claims about sexual climax, ranging from the bizarre to the hilarious. (This talk is aimed at adults. Viewer discretion advised.)

In his typically candid style, Richard St. John reminds us that success is not a one-way street, but a constant journey. He uses the story of his business' rise and fall to illustrate a valuable lesson — when we stop trying, we fail.

Behavioral economist Dan Ariely, the author of Predictably Irrational, uses classic visual illusions and his own counterintuitive (and sometimes shocking) research findings to show how we're not as rational as we think when we make decisions.

In this fun, 3-min performance from the World Science Festival, musician Bobby McFerrin uses the pentatonic scale to reveal one surprising result of the way our brains are wired.

Alain de Botton examines our ideas of success and failure -- and questions the assumptions underlying these two judgments. Is success always earned? Is failure? He makes an eloquent, witty case to move beyond snobbery to find true pleasure in our work.

For tens of thousands of years our ancestors understood the world through myths, and the pace of change was glacial. The rise of scientific understanding transformed the world within a few centuries. Why? Physicist David Deutsch proposes a subtle answer.

Career analyst Dan Pink examines the puzzle of motivation, starting with a fact that social scientists know but most managers don't: Traditional rewards aren't always as effective as we think. Listen for illuminating stories -- and maybe, a way forward. Bidding adieu to his last "real job" as Al Gore's speechwriter, Dan Pink went freelance to spark a right-brain revolution in the career marketplace.

Advertising adds value to a product by changing our perception, rather than the product itself. Rory Sutherland makes the daring assertion that a change in perceived value can be just as satisfying as what we consider “real” value -- and his conclusion has interesting consequences for how we look at life.

The varieties of wheat, corn and rice we grow today may not thrive in a future threatened by climate change. Cary Fowler takes us inside a vast global seed bank, buried within a frozen mountain in Norway, that stores a diverse group of food-crop for whatever tomorrow may bring.

We worry that IM, texting, Facebook are spoiling human intimacy, but Stefana Broadbent's research shows how communication tech is capable of cultivating deeper relationships, bringing love across barriers like distance and workplace rules.

Simon Sinek has a simple but powerful model for inspirational leadership — starting with a golden circle and the question "Why?" His examples include Apple, Martin Luther King, and the Wright brothers ...

Robert Wright uses evolutionary biology and game theory to explain why we appreciate the Golden Rule ("Do unto others..."), why we sometimes ignore it and why there’s hope that, in the near future, we might all have the compassion to follow it.

It's hard to always show compassion — even to the people we love, but Robert Thurman asks that we develop compassion for our enemies. He prescribes a seven-step meditation exercise to extend compassion beyond our inner circle.

At TEDIndia, Pranav Mistry demos several tools that help the physical world interact with the world of data -- including a deep look at his SixthSense device and a new, paradigm-shifting paper "laptop." In an onstage Q&A, Mistry says he'll open-source the software behind SixthSense, to open its possibilities to all.
