In this image-filled talk, Yann Arthus-Bertrand displays his three most recent projects on humanity and our habitat -- stunning aerial photographs in his series "The Earth From Above," personal interviews from around the globe featured in his web project "6 billion Others," and his soon-to-be-released movie, "Home," which documents human impact on the environment through breathtaking video. You might link the 6 billion Others wheel-chair guy to Kevin Bring his book to show the class Find the links to Home and 6 billion others
Clifford Stoll captivates his audience with a wildly energetic sprinkling of anecdotes, observations, asides -- and even a science experiment. After all, by his own definition, he's a scientist: "Once I do something, I want to do something else."
Athlete, actor and activist Aimee Mullins talks about her prosthetic legs -- she's got a dozen amazing pairs -- and the superpowers they grant her: speed, beauty, an extra 6 inches of height ... Quite simply, she redefines what the body can be. Mullins was born with fibular hemimelia (missing fibula bones) and, as a result, had both of her legs amputated below the knee when she was a year old.
Is the beloved paper dictionary doomed to extinction? In this infectiously exuberant talk, leading lexicographer Erin McKean looks at the many ways today's print dictionary is poised for transformation.
How many poets could cram eBay, Friendster and Monster.com into 3-minute poem worthy of a standing ovation? Enjoy Rives' unique talent.
When the dotcom bubble burst, hotelier Chip Conley went in search of a business model based on happiness. In an old friendship with an employee and in the wisdom of a Buddhist king, he learned that success comes from what you count.
Statistician Nic Marks asks why we measure a nation's success by its productivity -- instead of by the happiness and well-being of its people. He introduces the Happy Planet Index, which tracks national well-being against resource use (because a happy life doesn't have to cost the earth). Which countries rank highest in the HPI? You might be surprised.
Dan Gilbert, author of Stumbling on Happiness, challenges the idea that we’ll be miserable if we don’t get what we want. Our "psychological immune system" lets us feel truly happy even when things don’t go as planned. This is the talk about synthetic happiness.
Martin Seligman talks about psychology -- as a field of study and as it works one-on-one with each patient and each practitioner. As it moves beyond a focus on disease, what can modern psychology help us to become?
At his Stanford University commencement speech, Steve Jobs, CEO and co-founder of Apple and Pixar, urges us to pursue our dreams and see the opportunities in life's setbacks -- including death itself.
Sir Ken Robinson makes an entertaining and profoundly moving case for creating aneducation system that nurtures (rather than undermines) creativity. TED 2006 Theme: Education

Bill Gates hopes to solve some of the world's biggest problems using a new kind of philanthropy. In a passionate and, yes, funny 18 minutes, he asks us to consider two big questions and how we might answer them. (And see the Q&A on the TED Blog.)
Bennington president Liz Coleman delivers a call-to-arms for radical reform in higher education. Bucking the trend to push students toward increasingly narrow areas of study, she proposes a truly cross-disciplinary education -- one that dynamically combines all areas of study to address the great problems of our day.
In this poignant, funny follow-up to his fabled 2006 talk, Sir Ken Robinson makes the case for a radical shift from standardized schools to personalized learning -- creating conditions where kids' natural talents can flourish. TED 2010 Theme: Education
Today's math curriculum is teaching students to expect -- and excel at -- paint-by-numbers classwork, robbing kids of a skill more important than solving problems: formulating them. At TEDxNYED, Dan Meyer shows classroom-tested math exercises that prompt students to stop and think.
Someone always asks the math teacher, "Am I going to use calculus in real life?" And for most of us, says Arthur Benjamin, the answer is no. He offers a bold proposal on how to make math education relevant in the digital age.
Our lives, our cultures, are composed of many overlapping stories. Novelist Chimamanda Adichie tells the story of how she found her authentic cultural voice -- and warns that if we hear only a single story about another person or country, we risk a critical misunderstanding.
Psychologist Jonathan Haidt studies the five moral values that form the basis of our political choices, whether we're left, right or center. In this eye-opening talk, he pinpoints the moral values that liberals and conservatives tend to honor most.
"There's a flip side to everything," the saying goes, and in 2 minutes, Derek Sivers shows this is true in a few ways you might not expect.
Listening to stories widens the imagination; telling them lets us leap over cultural walls, embrace different experiences, feel what others feel. Elif Shafak builds on this simple idea to argue that fiction can overcome identity politics. Link this to Chimamanda Adichie
Devdutt Pattanaik takes an eye-opening look at the myths of India and of the West -- and shows how these two fundamentally different sets of beliefs about God, death and heaven help us consistently misunderstand one another.
Games like World of Warcraft give players the means to save worlds, and incentive to learn the habits of heroes. What if we could harness this gamer power to solve real-world problems? Jane McGonigal says we can, and explains how.
By now, we're used to letting Facebook and Twitter capture our social lives on the web -- building a "social layer" on top of the real world. At TEDxBoston, Seth Priebatsch looks at the next layer in progress: the "game layer," a pervasive net of behavior-steering game dynamics that will reshape education and commerce.
Kaki King, the first female on Rolling Stone's "guitar god" list, rocks out to a full live set at TED2008, including her breakout single, "Playing with Pink Noise." Jaw-dropping virtuosity meets a guitar technique that truly stands out.
Games are invading the real world -- and the runaway popularity of Farmville and Guitar Hero is just the beginning, says Jesse Schell. At the DICE Summit, he makes a startling prediction: a future where 1-ups and experience points break "out of the box" and into every part of our daily lives.
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
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.
Sugar pills, injections of nothing -- studies show that, more often than you'd expect, placebos really work. At TEDMED, magician Eric Mead does a trick to prove that, even when you know something's not real, you can still react as powerfully as if it is. (Warning: This talk is not suitable for viewers who are disturbed by needles or blood.)
Anthropologist Helen Fisher takes on a tricky topic -- love –- and explains its evolution, its biochemical foundations and its social importance. She closes with a warning about the potential disaster inherent in antidepressant abuse.
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.
The land of the free has become a legal minefield, says Philip K. Howard -- especially for teachers and doctors, whose work has been paralyzed by fear of suits. What's the answer? A lawyer himself, Howard has four propositions for simplifying US law.
Democracy thrives on civil debate, Michael Sandel says -- but we're shamefully out of practice. He leads a fun refresher, with TEDsters sparring over a recent Supreme Court case (PGA Tour, Inc. v. Martin) whose outcome reveals the critical ingredient in justice.
Is torture ever justified? Would you steal a drug that your child needs to survive? Is it sometimes wrong to tell the truth? How much is one human life worth? In the "Justice" program that bears his name, Harvard professor Michael Sandel probes these questions -- and asks what you think, and why.
Copyright law's grip on film, music and software barely touches the fashion industry ... and fashion benefits in both innovation and sales, says Johanna Blakley. At TEDxUSC 2010, she talks about what all creative industries can learn from fashion's free culture.
Margaret Gould Stewart, YouTube's head of user experience, talks about how the ubiquitous video site works with copyright holders and creators to foster (at the best of times) a creative ecosystem where everybody wins.

At TEDxNYED, former "young Republican" Larry Lessig talks about what Democrats can learn about copyright from their opposite party, considered more conservative. A surprising lens on remix culture. You may want to put this on in the auxiliary since the 07 talk is so great. It does have him editing Wikipedia.
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.
Tom Wujec presents some surprisingly deep research into the "marshmallow problem" -- a simple team-building exercise that involves dry spaghetti, one yard of tape and a marshmallow. Who can build the tallest tower with these ingredients? And why does a surprising group always beat the average?
At TEDGlobal 2010, author Matt Ridley shows how, throughout history, the engine of human progress has been the meeting and mating of ideas to make new ideas. It's not important how clever individuals are, he says; what really matters is how smart the collective brain is.
Pianist and composer Jennifer Lin gives a magical performance, talks about the process of creativity and improvises a moving solo piece based on a random sequence of notes.
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.
Why do people see the Virgin Mary on a cheese sandwich or hear demonic lyrics in "Stairway to Heaven"? Using video and music, skeptic Michael Shermer shows how we convince ourselves to believe -- and overlook the facts.
Biologist Richard Dawkins makes a case for "thinking the improbable" by looking at how the human frame of reference limits our understanding of the universe.
"Can we create new life out of our digital universe?" Craig Venter asks. His answer is "yes" -- and pretty soon. He walks through his latest research and promises that we'll soon be able to build and boot up a synthetic chromosome.
Juan Enriquez challenges our definition of bioenergy. Oil, coal, gas and other hydrocarbons are not chemical but biological products, based on plant matter -- and thus, growable. Our whole approach to fuel, he argues, needs to change.
One-of-a-kind R&B group Naturally 7 beatboxes an orchestra's worth of instruments to groove through their smooth single, "Fly Baby."

Product designer Eben Bayer reveals his recipe for a new, fungus-based packaging material that protects fragile stuff like furniture, plasma screens -- and the environment.
Environmental scientist David Keith proposes a cheap, effective, shocking means to address climate change: What if we injected a huge cloud of ash into the atmosphere to deflect sunlight and heat? An excellent talk about the role of science and how new technologies bring on new problems. Do we want to engineer the environment? Should we even talk about it?
Animal fan Nellie McKay sings a sparkling tribute to her dear dog. She suggests we all do the same: "Just go right to the pound/ And find yourself a hound/ And make that doggie proud/ 'cause that's what it's all about."
We all know the arguments that being vegetarian is better for the environment and for the animals -- but in a carnivorous culture, it can be hard to make the change. Graham Hill has a powerful, pragmatic suggestion: Be a weekday veg.
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.
What if human consciousness isn't the end-all and be-all of Darwinism? What if we are all just pawns in corn's clever strategy game to rule the Earth? Author Michael Pollan asks us to see the world from a plant's-eye view.
In a short, funny, data-packed talk at TED U, Catherine Mohr walks through all the geeky decisions she made when building a green new house -- looking at real energy numbers, not hype. What choices matter most? Not the ones you think.
Nuclear power: the energy crisis has even die-hard environmentalists reconsidering it. In this first-ever TED debate, Stewart Brand and Mark Z. Jacobson square off over the pros and cons. A discussion that'll make you think -- and might even change your mind.
Robin Chase founded Zipcar, the world’s biggest car-sharing business. That was one of her smaller ideas. Here she travels much farther, contemplating road-pricing schemes that will shake up our driving habits and a mesh network vast as the Interstate.

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.
Benjamin Zander has two infectious passions: classical music, and helping us all realize our untapped love for it -- and by extension, our untapped love for all new possibilities, new experiences, new connections.
In a lively show, mathemagician Arthur Benjamin races a team of calculators to figure out 3-digit squares, solves another massive mental equation and guesses a few birthdays.

Neuroscientist Vilayanur Ramachandran outlines the fascinating functions of mirror neurons. Only recently discovered, these neurons allow us to learn complex social behaviors, some of which formed the foundations of human civilization as we know it.
Jill Bolte Taylor got a research opportunity few brain scientists would wish for: She had a massive stroke, and watched as her brain functions -- motion, speech, self-awareness -- shut down one by one. An astonishing story.
Vilayanur Ramachandran tells us what brain damage can reveal about the connection between celebral tissue and the mind, using three startling delusions as examples.
Neuroscientist and inventor Christopher deCharms demonstrates a new way to use fMRI to show brain activity -- thoughts, emotions, pain -- while it is happening. In other words, you can actually see how you feel.
Richard Dawkins urges all atheists to openly state their position -- and to fight the incursion of the church into politics and science. A fiery, funny, powerful talk.

Speaking at the most recent EG conference, author, philosopher, prankster and journalist A.J. Jacobs talks about the year he spent living biblically -- following the rules in the Bible as literally as possible.
Anthropologist Wade Davis muses on the worldwide web of belief and ritual that makes us human. He shares breathtaking photos and stories of the Elder Brothers, a group of Sierra Nevada indians whose spiritual practice holds the world in balance.
Mark Roth studies suspended animation: the art of shutting down life processes and then starting them up again. It's wild stuff, but it's not science fiction. Induced by careful use of an otherwise toxic gas, suspended animation can potentially help trauma and heart attack victims survive long enough to be treated.
Biochemist Gregory Petsko makes a convincing argument that, in the next 50 years, we'll see an epidemic of neurological diseases, such as Alzheimer's, as the world population ages. His solution: more research into the brain and its functions.
Cambridge researcher Aubrey de Grey argues that aging is merely a disease -- and a curable one at that. Humans age in seven basic ways, he says, all of which can be averted. Here is a link to the TechReview outcome on the challanges to de Grey's argument. http://www.technologyreview.com/sens/index.aspx
