TED is a nonprofit devoted to Ideas Worth Spreading. It started out (in 1984) as a conference bringing together people from three worlds: Technology, Entertainment, Design. TEDTalks began as a simple attempt to share what happens at TED with the world. Under the moniker "ideas worth spreading," talks were released online. They rapidly attracted a global audience in the millions. Indeed, the reaction was so enthusiastic that the entire TED website has been reengineered around TEDTalks, with the goal of giving everyone on-demand access to the world's most inspiring voices. [TED-Ed and TEDx are separate TVDB series and should NOT be listed here.]
Oklahoma City is a midsized town that had a big problem: It was among the most obese towns in America. Mayor Mick Cornett realized that, to make his city a great place to work and live, it had to become healthier too. In this charming talk, he walks us through the interlocking changes that helped OKC drop a collective million pounds (450,000 kilos).
"I have cerebral palsy. I shake all the time," Maysoon Zayid announces at the beginning of this exhilarating, hilarious talk. (Really, it's hilarious.) "I'm like Shakira meets Muhammad Ali." With grace and wit, the Arab-American comedian takes us on a whistle-stop tour of her adventures as an actress, stand-up comic, philanthropist and advocate for the disabled.
More and more, English is a global language; speaking it is perceived as a sign of being modern. But — what do we lose when we leave behind our mother tongues? Suzanne Talhouk makes an impassioned case to love your own language, and to cherish what it can express that no other language can. In Arabic with subtitles. (Filmed at TEDxBeirut.)
Believe it or not, about 20 years' worth of potentially life-saving drugs are sitting in labs right now, untested. Why? Because they can't get the funding to go to trials; the financial risk is too high. Roger Stein is a finance guy, and he thinks deeply about mitigating risk. He and some colleagues at MIT came up with a promising new financial model that could move hundreds of drugs into the testing pipeline. (Filmed at [email protected])
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.
Imagine if you could surf Facebook ... from the Middle Ages. Well, it may not be as far off as it sounds. In a fun and interesting talk, researcher and engineer Frederic Kaplan shows off the Venice Time Machine, a project to digitize 80 kilometers of books to create a historical and geographical simulation of Venice across 1000 years. (Filmed at TEDxCaFoscariU.)
The music industry has sometimes struggled to find its feet in the digital world. In this lovely talk, TED Fellow Ryan Holladay tells us why he is experimenting with what he describes as "location-aware music." This programming and musical feat involves hundreds of geotagged segments of sounds that only play when a listener is physically nearby. (Filmed at [email protected])
You might not expect the chief operating officer of a major global corporation to look too far beyond either the balance sheet or the bottom line. But Harish Manwani, COO of Unilever, makes a passionate argument that doing so to include value, purpose and sustainability in top-level decision-making is not just savvy, it's the only way to run a 21st century business responsibly.
One hundred sixty years after the invention of the needle and syringe, we’re still using them to deliver vaccines; it’s time to evolve. Biomedical engineer Mark Kendall demos the Nanopatch, a one-centimeter-by-one-centimeter square vaccine that can be applied painlessly to the skin. He shows how this tiny piece of silicon can overcome four major shortcomings of the modern needle and syringe, at a fraction of the cost.
Sheryl Sandberg admits she was terrified to step onto the TED stage in 2010 — because she was going to talk, for the first time, about the lonely experience of being a woman in the top tiers of business. Millions of views (and a best-selling book) later, the Facebook COO talks with the woman who pushed her to give that first talk, Pat Mitchell. Sandberg opens up about the reaction to her idea, and explores the ways that women still struggle with success.
Luke Syson was a curator of Renaissance art, of transcendent paintings of saints and solemn Italian ladies — serious art. And then he changed jobs, and inherited the Met's collection of ceramics — pretty, frilly, "useless" candlesticks and vases. He didn't like it. He didn't get it. Until one day … (Filmed at TEDxMet.)
What kind of robots does an animator / jazz musician / roboticist make? Playful, reactive, curious ones. Guy Hoffman shows demo film of his family of unusual robots — including two musical bots that like to jam with humans.
“If you really want to know a people, start by looking inside their bedrooms," says Shereen El Feki, who traveled through the Middle East for five years, talking to people about sex. While those conversations reflected rigid norms and deep repression, El Feki also discovered that sexual conservatism in the Arab world is a relatively new thing. She wonders: could a re-emergence of public dialogue lead to more satisfying, and safer, sex lives?
Every cell in the human body has a sex, which means that men and women are different right down to the cellular level. Yet too often, research and medicine ignore this insight — and the often startlingly different ways in which the two sexes respond to disease or treatment. As pioneering doctor Paula Johnson describes in this thought-provoking talk, lumping everyone in together means we essentially leave women's health to chance. It's time to rethink.
Why do people feel so miserable and disengaged at work? Because today's businesses are increasingly and dizzyingly complex — and traditional pillars of management are obsolete, says Yves Morieux. So, he says, it falls to individual employees to navigate the rabbit's warren of interdependencies. In this energetic talk, Morieux offers six rules for "smart simplicity." (Rule One: Understand what your colleagues actually do.)
Humanity's fine-tuned sense of fear served us well as a young species, giving us laser focus to avoid being eaten by competing beasts. But it's less wonderful when that same visceral, body-hijacking sense of fear kicks in in front of 20 folk-music fans at a Tuesday night open-mic. Palms sweat, hands shake, vision blurs, and the brain says RUN: it's stage fright. In this charming, tuneful little talk, Joe Kowan talks about how he conquered it.
2013 was a year of hype for MOOCs (massive open online courses). Great big numbers and great big hopes were followed by some disappointing first results. But the head of edX, Anant Agarwal, makes the case that MOOCs still matter — as a way to share high-level learning widely and supplement (but perhaps not replace) traditional classrooms. Agarwal shares his vision of blended learning, where teachers create the ideal learning experience for 21st century students.
When she became the attorney general of New Jersey in 2007, Anne Milgram quickly discovered a few startling facts: not only did her team not really know who they were putting in jail, but they had no way of understanding if their decisions were actually making the public safer. And so began her ongoing, inspirational quest to bring data analytics and statistical analysis to the US criminal justice system.
McKenna Pope's younger brother loved to cook, but he worried about using an Easy-Bake Oven — because it was a toy for girls. So at age 13, Pope started an online petition for the American toy company Hasbro to change the pink-and-purple color scheme on the classic toy and incorporate boys into its TV marketing. In a heartening talk, Pope makes the case for gender-neutral toys and gives a rousing call to action to all kids who feel powerless.
Animal behavior isn't complicated, but it is complex. Nicolas Perony studies how individual animals — be they Scottish Terriers, bats or meerkats — follow simple rules that, collectively, create larger patterns of behavior. And how this complexity born of simplicity can help them adapt to new circumstances, as they arise.
Maya Penn started her first company when she was 8 years old, and thinks deeply about how to be responsible both to her customers and to the planet. She shares her story — and some animations, and some designs, and some infectious energy — in this charming talk.
When Esta Soler lobbied for a bill outlawing domestic violence in 1984, one politician called it the "Take the Fun Out of Marriage Act." "If only I had Twitter then," she mused. This sweeping, optimistic talk charts 30 years of tactics and technologies — from the Polaroid camera to social media — that led to a 64% drop in domestic violence in the U.S.
We're all familiar with satellite imagery, but what we might not know is that much of it is out of date. That's because satellites are big and expensive, so there aren't that many of them up in space. As he explains in this fascinating talk, Dan Berkenstock and his team came up with a different solution, designing a cheap, lightweight satellite with a radically new approach to photographing what's going on on Earth.
As the world's cities undergo explosive growth, inequality is intensifying. Wealthy neighborhoods and impoverished slums grow side by side, the gap between them widening. In this eye-opening talk, architect Teddy Cruz asks us to rethink urban development from the bottom up. Sharing lessons from the slums of Tijuana, Cruz explores the creative intelligence of the city's residents and offers a fresh perspective on what we can learn from places of scarcity.
Is there an equation for intelligence? Yes. It’s F = T ∇ Sτ. In a fascinating and informative talk, physicist and computer scientist Alex Wissner-Gross explains what in the world that means. (Filmed at TEDxBeaconStreet.)
In this charming talk, artist Aparna Rao shows us her latest work: cool, cartoony sculptures (with neat robotic tricks underneath them) that play with your perception — and crave your attention. Take a few minutes to simply be delighted.
In this thoughtful talk, David Puttnam asks a big question about the media: Does it have a moral imperative to create informed citizens, to support democracy? His solution for ensuring media responsibility is bold, and you might not agree. But it's certainly a question worth asking ... (Filmed at TEDxHousesofParliament.)
Most of us want to do the right thing when it comes to the environment. But things aren’t as simple as opting for the paper bag, says sustainability strategist Leyla Acaroglu. A bold call for us to let go of tightly-held green myths and think bigger in order to create systems and products that ease strain on the planet.
Sustainability is pretty clearly one of the world's most important goals; but what groups can really make environmental progress in leaps and bounds? Chris McKnett makes the case that it's large institutional investors. He shows how strong financial data isn't enough, and reveals why investors need to look at a company's environmental, social and governance structures, too.
Many of those with severe speech disorders use a computerized device to communicate. Yet they choose between only a few voice options. That's why Stephen Hawking has an American accent, and why many people end up with the same voice, often to incongruous effect. Speech scientist Rupal Patel wanted to do something about this, and in this wonderful talk she shares her work to engineer unique voices for the voiceless.
In this delightful talk, philosopher Yann Dall’Aglio explores the universal search for tenderness and connection in a world that's ever more focused on the individual. As it turns out, it's easier than you think. A wise and witty reflection on the state of love in the modern age. (Filmed at TEDxParis.)
What does it take to regrow bone in mass quantities? Typical bone regeneration — wherein bone is taken from a patient’s hip and grafted onto damaged bone elsewhere in the body — is limited and can cause great pain just a few years after operation. In an informative talk, Molly Stevens introduces a new stem cell application that harnesses bone’s innate ability to regenerate and produces vast quantities of bone tissue painlessly.
The world is full of leadership programs, but the best way to learn how to lead might be right under your nose. In this clear, candid talk, Roselinde Torres describes 25 years observing truly great leaders at work, and shares the three simple but crucial questions would-be company chiefs need to ask to thrive in the future.
An idea permeates our modern view of relationships: that men and women have always paired off in sexually exclusive relationships. But before the dawn of agriculture, humans may actually have been quite promiscuous. Author Christopher Ryan walks us through the controversial evidence that human beings are sexual omnivores by nature, in hopes that a more nuanced understanding may put an end to discrimination, shame and the kind of unrealistic expectations that kill relationships.
In this touching talk, Ash Beckham offers a fresh approach to empathy and openness. It starts with understanding that everyone, at some point in their life, has experienced hardship. The only way out, says Beckham, is to open the door and step out of your closet.
After a traumatic brain injury, it sometimes happens that the brain can repair itself, building new brain cells to replace damaged ones. But the repair doesn't happen quickly enough to allow recovery from degenerative conditions like motor neuron disease (also known as Lou Gehrig's disease or ALS). Siddharthan Chandran walks through some new techniques using special stem cells that could allow the damaged brain to rebuild faster.
Hacking is about more than mischief-making or political subversion. As Catherine Bracy describes in this spirited talk, it can be just as much a force for good as it is for evil. She spins through some inspiring civically-minded projects in Honolulu, Oakland and Mexico City — and makes a compelling case that we all have what it takes to get involved.
During the financial crisis, the central banks of the United States, United Kingdom and Japan created $3.7 trillion in order to buy assets and encourage investors to do the same. Michael Metcalfe offers a shocking idea: could these same central banks print money to ensure they stay on track with their goals for global aid? Without risking inflation?
In a fun, exciting talk, teenager Henry Lin looks at something unexpected in the sky: distant galaxy clusters. By studying the properties of the universe's largest pieces, says the Intel Science Fair award winner, we can learn quite a lot about scientific mysteries in our own world and galaxy.
The way we rate national economies is all wrong, says rating agency reformer Annette Heuser. With mysterious and obscure methods, three private US-based credit rating agencies wield immense power over national economies across the globe, and the outcomes can be catastrophic. But what if there was another way? In this bold talk, Heuser shares her vision for a nonprofit agency that would bring more equality and justice into the mix.
As an expert on cutting-edge digital displays, Mary Lou Jepsen studies how to show our most creative ideas on screens. And as a brain surgery patient herself, she is driven to know more about the neural activity that underlies invention, creativity, thought. She meshes these two passions in a rather mind-blowing talk on two cutting-edge brain studies that might point to a new frontier in understanding how (and what) we think.
What does the future of business look like? In an informative talk, Philip Evans gives a quick primer on two long-standing theories in strategy — and explains why he thinks they are essentially invalid.
Privacy researcher Christopher Soghoian sees the landscape of government surveillance shifting beneath our feet, as an industry grows to support monitoring programs. Through private companies, he says, governments are buying technology with the capacity to break into computers, steal documents and monitor activity — without detection. This TED Fellow gives an unsettling look at what's to come.
Vending machines generally offer up sodas, candy bars and chips. Not so for the one created by TED Fellow Gabe Barcia-Colombo. This artist has dreamed up a DNA Vending Machine, which dispenses extracted human DNA, packaged in a vial along with a collectible photo of the person who gave it. It’s charming and quirky, but points out larger ethical issues that will arise as access to biotechnology increases.
Perhaps you’ve punched out a paper doll or folded an origami swan? TED Fellow Manu Prakash and his team have created a microscope made of paper that's just as easy to fold and use. A sparkling demo that shows how this invention could revolutionize healthcare in developing countries … and turn almost anything into a fun, hands-on science experiment.
While working with kids who have trouble speaking, Ajit Narayanan sketched out a way to think about language in pictures, to relate words and concepts in "maps." The idea now powers an app that helps nonverbal people communicate, and the big idea behind it, a language concept called FreeSpeech, has exciting potential.
Ready to dance in your seat? Drummer Clayton Cameron breaks down different genres of music—from R&B to Latin to pop—by their beats. A talk that proves hip hop and jazz aren't cooler than math—they simply rely on it.
Public policy expert Anne-Marie Slaughter made waves with her 2012 article, "Why women still can't have it all." But really, is this only a question for women? Here Slaughter expands her ideas and explains why shifts in work culture, public policy and social mores can lead to more equality — for men, women, all of us.
Are the simplest phones the smartest? While the rest of the world is updating statuses and playing games on smartphones, Africa is developing useful SMS-based solutions to everyday needs, says journalist Toby Shapshak. In this eye-opening talk, Shapshak explores the frontiers of mobile invention in Africa as he asks us to reconsider our preconceived notions of innovation.
Think you know a thing or two about sex? Think again. In this fascinating talk, biologist Carin Bondar lays out the surprising science behind how animals get it on. (This talk describes explicit and aggressive sexual content.)
Here's a TED first: an animated Socratic dialog! In a time when irrationality seems to rule both politics and culture, has reasoned thinking finally lost its power? Watch as psychologist Steven Pinker is gradually, brilliantly persuaded by philosopher Rebecca Newberger Goldstein that reason is actually the key driver of human moral progress, even if its effect sometimes takes generations to unfold. The dialog was recorded live at TED, and animated, in incredible, often hilarious, detail by Cognitive.
Daniel Reisel studies the brains of criminal psychopaths (and mice). And he asks a big question: Instead of warehousing these criminals, shouldn’t we be using what we know about the brain to help them rehabilitate? Put another way: If the brain can grow new neural pathways after an injury … could we help the brain re-grow morality?
Appearing by telepresence robot, Edward Snowden speaks at TED2014 about surveillance and Internet freedom. The right to data privacy, he suggests, is not a partisan issue, but requires a fundamental rethink of the role of the internet in our lives — and the laws that protect it. "Your rights matter,” he says, "because you never know when you're going to need them." Chris Anderson interviews, with special guest Tim Berners-Lee.
There's an astronaut saying: In space, “there is no problem so bad that you can’t make it worse.” So how do you deal with the complexity, the sheer pressure, of dealing with dangerous and scary situations? Retired colonel Chris Hadfield paints a vivid portrait of how to be prepared for the worst in space (and life) — and it starts with walking into a spider’s web. Watch for a special space-y performance.
Anonymous companies protect corrupt individuals – from notorious drug cartel leaders to nefarious arms dealers – behind a shroud of mystery that makes it almost impossible to find and hold them responsible. But anti-corruption activist Charmian Gooch hopes to change all that. At TED2014, she shares her brave TED Prize wish: to know who owns and controls companies, to change the law, and to launch a new era of openness in business.
After a surprise appearance by Edward Snowden at TED2014, Chris Anderson said: "If the NSA wants to respond, please do." And yes, they did. Appearing by video, NSA deputy director Richard Ledgett answers Anderson’s questions about the balance between security and protecting privacy.
Onstage at TED2014, Charlie Rose interviews Google CEO Larry Page about his far-off vision for the company. It includes aerial bikeways and internet balloons … and then it gets even more interesting, as Page talks through the company’s recent acquisition of Deep Mind, an AI that is learning some surprising things.
Pakistani educator Ziauddin Yousafzai reminds the world of a simple truth that many don’t want to hear: Women and men deserve equal opportunities for education, autonomy, an independent identity. He tells stories from his own life and the life of his daughter, Malala, who was shot by the Taliban in 2012 simply for daring to go to school. "Why is my daughter so strong?” Yousafzai asks. “Because I didn’t clip her wings."
When Bran Ferren was just 9, his parents took him to see the Pantheon in Rome — and it changed everything. In that moment, he began to understand how the tools of science and engineering become more powerful when combined with art, with design and beauty. Ever since, he's been searching for a convincing modern-day equivalent to Rome's masterpiece. Stay tuned to the end of the talk for his unexpected suggestion.
We humans set a premium on our own free will and independence ... and yet there's a shadowy influence we might not be considering. As science writer Ed Yong explains in this fascinating, hilarious and disturbing talk, parasites have perfected the art of manipulation to an incredible degree. So are they influencing us? It's more than likely.
When hundreds of thousands of tweets are fired every second, a one-in-a-million chance — including unlikely-sounding scenarios that could harm users — happens about 500 times a day. For Del Harvey, who heads Twitter’s Trust and Safety Team, these odds aren’t good. The security maven spends her days thinking about how to prevent worst-case scenarios while giving voice to people around the globe. With deadpan humor, she offers a window into how she keeps 240 million users safe.
Hugh Herr is building the next generation of bionic limbs, robotic prosthetics inspired by nature's own designs. Herr lost both legs in a climbing accident 30 years ago; now, as the head of the MIT Media Lab’s Biomechatronics group, he shows his incredible technology in a talk that's both technical and deeply personal — with the help of ballroom dancer Adrianne Haslet-Davis, who lost her left leg in the 2013 Boston Marathon bombing, and performs again for the first time on the TED stage.
When fashion model Geena Rocero first saw a photo of herself in a bikini, "I thought ... you have arrived!" As she reveals, that’s because she was born with the gender assignment “boy.” In this moving talk, Rocero tells the story of becoming who she always knew she was.

On March 17, 2014, a group of physicists announced a thrilling discovery: the “smoking gun” data for the idea of an inflationary universe, a clue to the Big Bang. For non-physicists, what does it mean? TED asked Allan Adams to briefly explain the results, in this improvised talk illustrated by Randall Munroe of xkcd.
In 1993, Bill and Melinda Gates took a walk on the beach and made a big decision: to give their Microsoft wealth back to society. In conversation with Chris Anderson, the couple talks about their work at the Bill & Melinda Gates Foundation, as well as their marriage, their children, their failures and the satisfaction of giving most of their money away.
Do you like curly fries? Have you Liked them on Facebook? Watch this talk to find out the surprising things Facebook (and others) can guess about you from your random Likes and Shares. Computer scientist Jennifer Golbeck explains how this came about, how some applications of the technology are not so cute — and why she thinks we should return the control of information to its rightful owners.
Seven years ago, Internet activist Aaron Swartz convinced Lawrence Lessig to take up the fight for political reform. A year after Swartz's tragic death, Lessig continues his campaign to free US politics from the stranglehold of corruption. In this fiery, deeply personal talk, he calls for all citizens to engage, and offers a heartfelt reminder to never give up hope.
More than 8 million people are crowded together to live in New York City. What makes it possible? In part, it’s the city’s great public spaces — from tiny pocket parks to long waterfront promenades — where people can stroll and play. Amanda Burden helped plan some of the city’s newest public spaces, drawing on her experience as, surprisingly, an animal behaviorist. She shares the unexpected challenges of planning parks people love — and why it's important.
What do rap shows, barbershop banter and Sunday services have in common? As Christopher Emdin says, they all hold the secret magic to enthrall and teach at the same time — and it’s a skill we often don't teach to educators. The science advocate (and cofounder of Science Genius B.A.T.T.L.E.S. with the GZA of the Wu-Tang Clan) offers a vision to make the classroom come alive.
We live in a world of unseeable beauty, so subtle and delicate that it is imperceptible to the human eye. To bring this invisible world to light, filmmaker Louie Schwartzberg bends the boundaries of time and space with high-speed cameras, time lapses and microscopes. At TED2014, he shares highlights from his latest project, a 3D film titled "Mysteries of the Unseen World," which slows down, speeds up, and magnifies the astonishing wonders of nature.
What drove David Sengeh to create a more comfortable prosthetic limb? He grew up in Sierra Leone, and too many of the people he loves are missing limbs after the brutal civil war there. When he noticed that people who had prosthetics weren’t actually wearing them, the TED Fellow set out to discover why — and to solve the problem with his team from the MIT Media Lab.
On January 8, 2011, Congresswoman Gabby Giffords was shot in the head while meeting constituents in her home town of Tucson, Arizona. Her husband, the astronaut Mark Kelly, immediately flew to be by her side. In this emotional conversation with Pat Mitchell, the pair describe their lives both before and after the accident — and describe their views on responsible gun ownership.
Within each of us are two selves, suggests David Brooks in this meditative short talk: the self who craves success, who builds a résumé, and the self who seeks connection, community, love — the values that make for a great eulogy. (Joseph Soloveitchik has called these selves "Adam I" and "Adam II.") Brooks asks: Can we balance these two selves?
The parenting section of the bookstore is overwhelming—it's "a giant, candy-colored monument to our collective panic," as writer Jennifer Senior puts it. Why is parenthood filled with so much anxiety? Because the goal of modern, middle-class parents—to raise happy children—is so elusive. In this honest talk, she offers some kinder and more achievable aims.
Puberty is an awkward time for just about everybody, but for transgender teens it can be a nightmare, as they grow overnight into bodies they aren't comfortable with. In a heartfelt talk, endocrinologist Norman Spack tells a personal story of how he became one of the few doctors in the US to treat minors with hormone replacement therapy. By staving off the effects of puberty, Spack gives trans teens the time they need. (Filmed at TEDxBeaconStreet.)
Astronomers believe that every star in the galaxy has a planet, one fifth of which might harbor life. Only we haven't seen any of them — yet. Jeremy Kasdin and his team are looking to change that with the design and engineering of an extraordinary piece of equipment: a flower petal-shaped "starshade" positioned 50,000 km from a telescope to enable imaging of planets about distant stars. It is, he says, the "coolest possible science."
Pick up a book, magazine or screen, and more than likely you'll come across some typography designed by Matthew Carter. In this charming talk, the man behind typefaces such as Verdana, Georgia and Bell Centennial (designed just for phone books — remember them?), takes us on a spin through a career focused on the very last pixel of each letter of a font.
At her first museum job, art historian Sarah Lewis noticed something important about an artist she was studying: Not every artwork was a total masterpiece. She asks us to consider the role of the almost-failure, the near win, in our own lives. In our pursuit of success and mastery, is it actually our near wins that push us forward?
Our energy future depends on nuclear fusion, says Michel Laberge. The plasma physicist runs a small company with a big idea for a new type of nuclear reactor that could produce clean, cheap energy. His secret recipe? High speeds, scorching temperatures and crushing pressure. In this hopeful talk, he explains how nuclear fusion might be just around the corner.
Hamish Jolly, an ocean swimmer in Australia, wanted a wetsuit that would deter a curious shark from mistaking him for a potential source of nourishment. (Which, statistically, is rare, but certainly a fate worth avoiding.) Working with a team of scientists, he and his friends came up with a fresh approach — not a shark cage, not a suit of chain-mail, but a sleek suit that taps our growing understanding of shark vision.
"The computer is an incredibly powerful means of creative expression," says designer and TED Fellow James Patten. But right now, we interact with computers, mainly, by typing and tapping. In this nifty talk and demo, Patten imagines a more visceral, physical way to bring your thoughts and ideas to life in the digital world, taking the computer interface off the screen and putting it into your hands.
Elizabeth Gilbert was once an "unpublished diner waitress," devastated by rejection letters. And yet, in the wake of the success of 'Eat, Pray, Love,' she found herself identifying strongly with her former self. With beautiful insight, Gilbert reflects on why success can be as disorienting as failure and offers a simple — though hard — way to carry on, regardless of outcomes.
In this factual talk, geneticist Wendy Chung shares what we know about autism spectrum disorder — for example, that autism has multiple, perhaps interlocking, causes. Looking beyond the worry and concern that can surround a diagnosis, Chung and her team look at what we’ve learned through studies, treatments and careful listening.
When you look at sporting achievements over the last decades, it seems like humans have gotten faster, better and stronger in nearly every way. Yet as David Epstein points out in this delightfully counter-intuitive talk, we might want to lay off the self-congratulation. Many factors are at play in shattering athletic records, and the development of our natural talents is just one of them.
Thirty-nine million people in the world are blind, and the majority lost their sight due to curable and preventable diseases. But how do you test and treat people who live in remote areas, where expensive, bulky eye equipment is hard to come by? TED Fellow Andrew Bastawrous demos a smartphone app and cheap hardware that might help.
You can't understand climate change in pieces, says climate scientist Gavin Schmidt. It's the whole, or it's nothing. In this illuminating talk, he explains how he studies the big picture of climate change with mesmerizing models that illustrate the endlessly complex interactions of small-scale environmental events.
Sarah Jones changes personas with the simplest of wardrobe swaps. In a laugh-out-loud improvisation, she invites 11 "friends" from the future on stage—from a fast-talking Latina to an outspoken police officer—to ask them questions supplied by the TED2014 audience.
The subject of race can be very touchy. As finance executive Mellody Hobson says, it's a "conversational third rail." But, she says, that's exactly why we need to start talking about it. In this engaging, persuasive talk, Hobson makes the case that speaking openly about race — and particularly about diversity in hiring — makes for better businesses and a better society.
Marco Tempest uses charming stagecraft to demo EDI, the multi-purpose robot designed to work very closely with humans. Less a magic trick than an intricately choreographed performance, Tempest shows off the robot’s sensing technology, safety features and strength, and makes the case for a closer human-robot relationship. (Okay, there’s a little magic, too.)
When General Stanley McChrystal started fighting al Qaeda in 2003, information and secrets were the lifeblood of his operations. But as the unconventional battle waged on, he began to think that the culture of keeping important information classified was misguided and actually counterproductive. In a short but powerful talk McChrystal makes the case for actively sharing knowledge.
Web cartoonist Randall Munroe answers simple what-if questions ("what if you hit a baseball moving at the speed of light?") using math, physics, logic and deadpan humor. In this charming talk, a reader’s question about Google's data warehouse leads Munroe down a circuitous path to a hilariously over-detailed answer — in which, shhh, you might actually learn something.
Sampling isn't about "hijacking nostalgia wholesale," says Mark Ronson. It's about inserting yourself into the narrative of a song while also pushing that story forward. In this mind-blowingly original talk, watch the DJ scramble 15 TED Talks into an audio-visual omelette, and trace the evolution of "La Di Da Di," Doug E. Fresh and Slick Rick's 1984 hit that has been reimagined for every generation since.
William Black is a former bank regulator who’s seen firsthand how banking systems can be used to commit fraud — and how “liar's loans” and other tricky tactics led to the 2008 US banking crisis that threatened the international economy. In this engaging talk, Black, now an academic, reveals the best way to rob a bank — from the inside.
Ecologist Deborah Gordon studies ants wherever she can find them — in the desert, in the tropics, in her kitchen ... In this fascinating talk, she explains her obsession with insects most of us would happily swat away without a second thought. She argues that ant life provides a useful model for learning about many other topics, including disease, technology and the human brain.
For many years Sergeant Kevin Briggs had a dark, unusual, at times strangely rewarding job: He patrolled the southern end of San Francisco’s Golden Gate Bridge, a popular site for suicide attempts. In a sobering, deeply personal talk Briggs shares stories from those he’s spoken — and listened — to standing on the edge of life. He gives a powerful piece of advice to those with loved ones who might be contemplating suicide.
Do our smells make us sexy? Popular science suggests yes — pheromones send chemical signals about sex and attraction from our armpits to potential mates.

It's a call for all of us to ask veterans to tell their stories -- and listen. www.ted.com/talks/view/id/2008
Civilians don't miss war. But soldiers often do. Journalist Sebastian Junger shares his experience embedded with American soldiers at Restrepo, an outpost in Afghanistan's Korengal Valley that saw heavy combat. Giving a look at the "altered state of mind" that comes with war, he shows how combat gives soldiers an intense experience of connection. In the end, could it actually be "the opposite of war" that soldiers miss? www.ted.com/talks/view/id/1999
In 1902, President Theodore Roosevelt legendarily spared the life of a black bear — and prompted a plush toy craze for so-called "teddy bears." Writer Jon Mooallem digs into this toy story and asks us to consider how the tales we tell about wild animals have real consequences for a species' chance of survival — and the natural world at large.
As a young girl, photojournalist and TED Fellow Kitra Cahana dreamed about running away from home to live freely on the road.

What can we learn from people with the genetics to get sick — who don’t? With most inherited diseases, only some family members will develop the disease, while others who carry the same genetic risks dodge it. Stephen Friend suggests we start studying those family members who stay healthy. Hear about the Resilience Project, a massive effort to collect genetic materials that may help decode inherited disorders.
Sting’s early life was dominated by a shipyard—and he dreamed of nothing more than escaping the industrial drudgery. But after a nasty bout of writer’s block that stretched on for years, Sting found himself channeling the stories of the shipyard workers he knew in his youth for song material. In a lyrical, confessional talk, Sting treats us to songs from his upcoming musical, and to an encore of “Message in a Bottle.”
Two hundred million years ago, our mammal ancestors developed a new brain feature: the neocortex. This stamp-sized piece of tissue (wrapped around a brain the size of a walnut) is the key to what humanity has become. Now, futurist Ray Kurzweil suggests, we should get ready for the next big leap in brain power, as we tap into the computing power in the cloud.
"Human beings are works in progress that mistakenly think they're finished." Dan Gilbert shares recent research on a phenomenon he calls the "end of history illusion," where we somehow imagine that the person we are right now is the person we'll be for the rest of time. Hint: that's not the case.
"We're all going to die — and poems can help us live with that." In a charming and funny talk, literary critic Stephen Burt takes us on a lyrical journey with some of his favorite poets, all the way down to a line break and back up to the human urge to imagine.

A powerful reminder that we all have a stake in equality.
Stella Young is a comedian and journalist who happens to go about her day in a wheelchair — a fact that doesn’t, she’d like to make clear, automatically turn her into a noble inspiration to all humanity. In this very funny talk, Young breaks down society's habit of turning disabled people into “inspiration porn.”
The beauty of hackers, says cybersecurity expert Keren Elazari, is that they force us to evolve and improve. Yes, some hackers are bad guys, but many are working to fight government corruption and advocate for our rights. By exposing vulnerabilities, they push the Internet to become stronger and healthier, wielding their power to create a better world.
In 2002, investigative journalist and TED Fellow Will Potter took a break from his regular beat, writing about shootings and murders for the Chicago Tribune. He went to help a local group campaigning against animal testing: "I thought it would be a safe way to do something positive," he says. Instead, he was arrested, and so began his ongoing journey into a world in which peaceful protest is branded as terrorism.
While studying for his PhD in physics, Uri Alon thought he was a failure because all his research paths led to dead ends.

Plenty of good things are done in the name of religion, and plenty of bad things too. But what is religion, exactly — is it good or bad, in and of itself? Philosopher Kwame Anthony Appiah offers a generous, surprising view.
One could argue that slang words like ‘hangry,’ ‘defriend’ and ‘adorkable’ fill crucial meaning gaps in the English language, even if they don't appear in the dictionary. After all, who actually decides which words make it into those pages? Language historian Anne Curzan gives a charming look at the humans behind dictionaries, and the choices they make.
Here's a talk that could literally change your life. Which career should I pursue? Should I break up — or get married?! Where should I live? Big decisions like these can be agonizingly difficult. But that's because we think about them the wrong way, says philosopher Ruth Chang. She offers a powerful new framework for shaping who we truly are.
Jamila Lyiscott is a “tri-tongued orator;” in her powerful spoken-word essay “Broken English,” she celebrates — and challenges — the three distinct flavors of English she speaks with her friends, in the classroom and with her parents. As she explores the complicated history and present-day identity that each language represents, she unpacks what it means to be “articulate.”
What must our dogs be thinking when they look at us? Poet Billy Collins imagines the inner lives of two very different companions. It’s a charming short talk, perfect for taking a break and dreaming…
In 1991, Shaka Senghor shot and killed a man. He was, he says, "a drug dealer with a quick temper and a semi-automatic pistol." Jailed for second degree murder, that could very well have been the end of the story. But it wasn't. Instead, it was the beginning of a years-long journey to redemption, one with humbling and sobering lessons for us all.
Lorrie Faith Cranor studied thousands of real passwords to figure out the surprising, very common mistakes that users — and secured sites — make to compromise security. And how, you may ask, did she study thousands of real passwords without compromising the security of any users? That's a story in itself. It's secret data worth knowing, especially if your password is 123456 ...
Many of the world's biggest problems require asking questions of scientists — but why should we believe what they say? Historian of science Naomi Oreskes thinks deeply about our relationship to belief and draws out three problems with common attitudes toward scientific inquiry — and gives her own reasoning for why we ought to trust science.

(It's not pretty.) Find out more astonishing facts about fireflies in Lewis' footnotes, below.
It's an unexpected side effect of globalization: problems that once would have stayed local—say, a bank lending out too much money—now have consequences worldwide. But still, countries operate independently, as if alone on the planet. Policy advisor Simon Anholt has dreamed up an unusual scale to get governments thinking outwardly: The Good Country Index. In a riveting and funny talk, he answers the question, "Which country does the most good?" The answer may surprise you (especially if you live in the US or China).
We often think of bias and prejudice as rooted in ignorance. But as psychologist Paul Bloom seeks to show, prejudice is often natural, rational ... even moral. The key, says Bloom, is to understand how our own biases work — so we can take control when they go wrong.
When he was a child, George Takei and his family were forced into an internment camp for Japanese-Americans, as a “security" measure during World War II. 70 years later, Takei looks back at how the camp shaped his surprising, personal definition of patriotism and democracy.
“Remember before the internet?” asks Joi Ito. “Remember when people used to try to predict the future?” In this engaging talk, the head of the MIT Media Lab skips the future predictions and instead shares a new approach to creating in the moment: building quickly and improving constantly, without waiting for permission or for proof that you have the right idea. This kind of bottom-up innovation is seen in the most fascinating, futuristic projects emerging today, and it starts, he says, with being open and alert to what’s going on around you right now. Don’t be a futurist, he suggests: be a now-ist.
MIT Media Lab founder Nicholas Negroponte takes you on a journey through the last 30 years of tech. The consummate predictor highlights interfaces and innovations he foresaw in the 1970s and 1980s that were scoffed at then but are ubiquitous today. And he leaves you with one last (absurd? brilliant?) prediction for the coming 30 years.
We face an endless string of choices, which leads us to feel anxiety, guilt and pangs of inadequacy that we are perhaps making the wrong ones. But philosopher Renata Salecl asks: Could individual choices be distracting us from something bigger—our power as social thinkers? A bold call for us to stop taking personal choice so seriously and focus on the choices we're making collectively.

Facebook’s “like” and “share” buttons are seen 22 billion times a day, making them some of the most-viewed design elements ever created. Margaret Gould Stewart, Facebook’s director of product design, outlines three rules for design at such a massive scale—one so big that the tiniest of tweaks can cause global outrage, but also so large that the subtlest of improvements can positively impact the lives of many.
Tour the deep dark world of the East German state security agency known as Stasi. Uniquely powerful at spying on its citizens, until the fall of the Berlin Wall in 1989 the Stasi masterminded a system of surveillance and psychological pressure that kept the country under control for decades. Hubertus Knabe studies the Stasi — and was spied on by them. He shares stunning details from the fall of a surveillance state, and shows how easy it was for neighbor to turn on neighbor.

The new breed of high-tech self-monitors (measuring heartrate, sleep, steps per day) might seem targeted at competitive athletes. But Talithia Williams, a statistician, makes a compelling case that all of us should be measuring and recording simple data about our bodies every day — because our own data can reveal much more than even our doctors may know.
Nick Hanauer is a rich guy, an unrepentant capitalist — and he has something to say to his fellow plutocrats: Wake up! Growing inequality is about to push our societies into conditions resembling pre-revolutionary France. Hear his argument about why a dramatic increase in minimum wage could grow the middle class, deliver economic prosperity ... and prevent a revolution.
In the United States, the agencies that govern prisons are often called ‘Department of Corrections.’ And yet, their focus is on containing and controlling inmates. Dan Pacholke, Deputy Secretary for the Washington State Department of Corrections, shares a different vision: of prisons that provide humane living conditions as well as opportunities for meaningful work and learning.
Far too many Americans are illiterate in power — what it is, how it operates and why some people have it. As a result, those few who do understand power wield disproportionate influence over everyone else. “We need to make civics sexy again,” says civics educator Eric Liu. “As sexy as it was during the American Revolution or the Civil Rights Movement.”
"We spend so much time listening to the things people are saying that we rarely pay attention to the things they don't," says poet and teacher Clint Smith. A short, powerful piece from the heart, about finding the courage to speak up against ignorance and injustice.
Sir Tim Berners-Lee invented the World Wide Web 25 years ago. So it’s worth a listen when he warns us: There’s a battle ahead. Eroding net neutrality, filter bubbles and centralizing corporate control all threaten the web’s wide-open spaces. It’s up to users to fight for the right to access and openness. The question is, What kind of Internet do we want?
The Fez River winds through the medina of Fez, Morocco—a mazelike medieval city that’s a World Heritage site. Once considered the “soul” of this celebrated city, the river succumbed to sewage and pollution, and in the 1950s was covered over bit by bit until nothing remained. TED Fellow Aziza Chaouni recounts her 20 year effort to restore this river to its former glory, and to transform her city in the process.

As a concerned member of the human race, he asks: What’s the worst thing that could possibly happen?
Across sub-Saharan Africa, small farmers are the bedrock of national and regional economies—unless the weather proves unpredictable and their crops fail. The solution is insurance, at a vast, continental scale, and at a very low, affordable cost. Rose Goslinga and the Syngenta Foundation for Sustainable Agriculture pioneered an unconventional way to give farmers whose crops fail early a second chance at a growing season.
This talk begins with a personal story of sexual violence that may be difficult to listen to. But that’s the point, says citizen journalist Meera Vijayann: Speaking out on tough, taboo topics is the spark for change. Vijayann uses digital media to speak honestly about her experience of gender violence in her home country of India — and calls on others to speak out too.
Doesn't it seem like a lot of online news sites have moved beyond reporting the news to openly inciting your outrage (and your page views)? News analyst Sally Kohn suggests — don't engage with news that looks like it just wants to make you mad. Instead, give your precious clicks to the news sites you truly trust.
Which of the following is awesome: your lunch or the Great Pyramid of Giza? Comedian Jill Shargaa sounds a hilarious call for us to save the word "awesome" for things that truly inspire awe.
Why is there something instead of nothing? In other words: Why does the universe exist (and why are we in it)? Philosopher and writer Jim Holt follows this question toward three possible answers. Or four. Or none.

Rishi Manchanda has worked as a doctor in South Central Los Angeles for a decade, where he’s come to realize: His job isn’t just about treating a patient’s symptoms, but about getting to the root cause of what is making them ill—the “upstream" factors like a poor diet, a stressful job, a lack of fresh air. It’s a powerful call for doctors to pay attention to a patient's life outside the exam room.
Big Data is everywhere — even the skies. In an informative talk, astronomer Andrew Connolly shows how large amounts of data are being collected about our universe, recording it in its ever-changing moods. Just how do scientists capture so many images at scale? It starts with a giant telescope …

Economist Dilip Ratha describes the promise of these “dollars wrapped with love” and analyzes how they are stifled by practical and regulatory obstacles.
Glenn Greenwald was one of the first reporters to see — and write about — the Edward Snowden files, with their revelations about the United States' extensive surveillance of private citizens. In this searing talk, Greenwald makes the case for why you need to care about privacy, even if you’re “not doing anything you need to hide."
The brain uses a quarter of the body's entire energy supply, yet only accounts for about two percent of the body's mass. So how does this unique organ receive and, perhaps more importantly, rid itself of vital nutrients? New research suggests it has to do with sleep.
Myriam Sidibe is a warrior in the fight against childhood disease. Her weapon of choice? A bar of soap. For cost-effective prevention against sickness, it’s hard to beat soapy hand-washing, which cuts down risk of pneumonia, diarrhea, cholera and worse.

Does a set of data make you feel more comfortable? More successful? Then your interpretation of it is likely wrong. In a surprisingly moving talk, Susan Etlinger explains why, as we receive more and more data, we need to deepen our critical thinking skills. Because it's hard to move beyond counting things to really understanding them.
Before he hit eighteen, Fred Swaniker had lived in Ghana, Gambia, Botswana and Zimbabwe. What he learned from a childhood across Africa was that while good leaders can't make much of a difference in societies with strong institutions, in countries with weak structures, leaders could make or break a country. In a passionate talk the entrepreneur and TED Fellow looks at different generations of African leaders and imagines how to develop the leadership of the future.

Every human deserves protection under their country’s laws — even when that law is forgotten or ignored. Sharing three cases from her international legal practice, Kimberley Motley, an American litigator practicing in Afghanistan and elsewhere, shows how a country’s own laws can bring both justice and “justness”: using the law for its intended purpose, to protect.
Let's admit it: aerial photo drones and UAVs are a little creepy, and they come with big regulatory and safety problems. But aerial photos can be a powerful way of telling the truth about the world: the size of a protest, the spread of an oil spill, the wildlife hidden in a delta. Sergei Lupashin demos Fotokite, a nifty new way to see the world from on high, safely and under control.
Nature photographer Frans Lanting uses vibrant images to take us deep into the animal world. In this short, visual talk he calls for us to reconnect with other earthly creatures, and to shed the metaphorical skins that separate us from each other.
Debra Jarvis had worked as a hospital chaplain for nearly 30 years when she was diagnosed with cancer. And she learned quite a bit as a patient.

We can see the power of distributed, crowd-sourced business models every day — witness Uber, Kickstarter, Airbnb. But veteran online activist Jeremy Heimans asks: When does that kind of "new power" start to work in politics? His surprising answer: Sooner than you think. It’s a bold argument about the future of politics and power; watch and see if you agree.
Too often, people feel checked out of politics — even at the level of their own city. But urban activist Alessandra Orofino thinks that can change, using a mix of tech and old-fashioned human connection. Sharing examples from her hometown of Rio, she says: "It is up to us to decide whether we want schools or parking lots, recycling projects or construction sites, cars or buses, loneliness or solidarity."

When asked to build housing for 100 families in Chile ten years ago, Alejandro Aravena looked to an unusual inspiration: the wisdom of favelas and slums. Rather than building a large building with small units, he built flexible half-homes that each family could expand on. It was a complex problem, but with a simple solution — one that he arrived at by working with the families themselves. With a chalkboard and beautiful images of his designs, Aravena walks us through three projects where clever rethinking led to beautiful design with great benefit.
Artists Jeroen Koolhaas and Dre Urhahn create community art by painting entire neighborhoods, and involving those who live there — from the favelas of Rio to the streets of North Philadelphia. What's made their projects succeed? In this funny and inspiring talk, the artists explain their art-first approach — and the importance of a neighborhood barbecue.
Antibiotic drugs save lives. But we simply use them too much — and often for non-lifesaving purposes, like treating the flu and even raising cheaper chickens. The result, says researcher Ramanan Laxminarayan, is that the drugs will stop working for everyone, as the bacteria they target grow more and more resistant. He calls on all of us (patients and doctors alike) to think of antibiotics — and their ongoing effectiveness — as a finite resource, and to think twice before we tap into it. It’s a sobering look at how global medical trends can strike home.
The term Gross Domestic Product is often talked about as if it were “handed down from god on tablets of stone.” But this concept was invented by an economist in the 1930s. We need a more effective measurement tool to match 21st century needs, says Michael Green: the Social Progress Index. With charm and wit, he shows how this tool measures societies across the three dimensions that actually matter. And reveals the dramatic reordering of nations that occurs when you use it.
Is the War on Drugs doing more harm than good? In a bold talk, drug policy reformist Ethan Nadelmann makes an impassioned plea to end the "backward, heartless, disastrous" movement to stamp out the drug trade. He gives two big reasons we should focus on intelligent regulation instead.
Wouldn’t you want to know if your doctor was a paid spokesman for a drug company? Or held personal beliefs incompatible with the treatment you want?

This year, explorer Ben Saunders attempted his most ambitious trek yet. He set out to complete Captain Robert Falcon Scott’s failed 1912 polar expedition — a four-month, 1,800-mile round trip journey from the edge of Antarctica to the South Pole and back. In the first talk given after his adventure, just five weeks after his return, Saunders offers a raw, honest look at this “hubris”-tinged mission that brought him to the most difficult decision of his life.
It sounds counterintuitive, but by 2030, many of the world's largest economies will have more jobs than adult citizens to do those jobs. In this data-filled — and quite charming — talk, human resources expert Rainer Strack suggests that countries ought to look across borders for mobile and willing job seekers. But to do that, they need to start by changing the culture in their businesses.

You've heard about slow food. Now here's slow ... TV? In this very funny talk, Norwegian television producer Thomas Hellum shares how he and his team began to broadcast long, boring events, often live — and found a rapt audience. Shows include a 7-hour train journey, an 18-hour fishing expedition and a 5.5-day ferry voyage along the coast of Norway. The results are both beautiful and fascinating. Really.
A very unsexy-sounding piece of technology could mean that the police know where you go, with whom, and when: the automatic license plate reader. These cameras are innocuously placed all across small-town America to catch known criminals, but as lawyer and TED Fellow Catherine Crump shows, the data they collect in aggregate could have disastrous consequences for everyone the world over.
Every city has its neighborhoods, cliques and clubs, the hidden lines that join and divide people in the same town. What can we learn about cities by looking at what people share online? Starting with his own home town of Baltimore, Dave Troy has been visualizing what the tweets of city dwellers reveal about who lives there, who they talk to — and who they don’t.
Our biases can be dangerous, even deadly — as we've seen in the cases of Michael Brown in Ferguson, Missouri, and Eric Garner, in Staten Island, New York.

Then move toward, not away from, the groups that make you uncomfortable. In a funny, impassioned, important talk, she shows us how.
What happens when we teach a computer how to learn? Technologist Jeremy Howard shares some surprising new developments in the fast-moving field of deep learning, a technique that can give computers the ability to learn Chinese, or to recognize objects in photos, or to help think through a medical diagnosis. (One deep learning tool, after watching hours of YouTube, taught itself the concept of “cats.”) Get caught up on a field that will change the way the computers around you behave … sooner than you probably think.
Carol Dweck researches “growth mindset” — the idea that we can grow our brain's capacity to learn and to solve problems. In this talk, she describes two ways to think about a problem that’s slightly too hard for you to solve. Are you not smart enough to solve it … or have you just not solved it yet? A great introduction to this influential field.
In 2011, journalist Bruno Torturra covered a protest in São Paulo which turned ugly.

It's a movement that is going global.
In this fun, short talk from TEDYouth, lexicographer Erin McKean encourages — nay, cheerleads — her audience to create new words when the existing ones won’t quite do. She lists out 6 ways to make new words in English, from compounding to “verbing,” in order to make language better at expressing what we mean, and to create more ways for us to understand one another.
