I was thinking about my place in the universe, and about my first thought about what infinity might mean, when I was a child. And I thought that if time could reach forwards and backwards infinitely, doesn't that mean that every point in time is really infinitely small, and therefore somewhat meaningless. So we don't r...
So magic is a very introverted field. While scientists regularly publish their latest research, we magicians do not like to share our methods and secrets. That's true even amongst peers. But if you look at creative practice as a form of research, or art as a form of R&D for humanity, then how could a cyber illusionist ...
♫ Like the heather ♫ ♫ on the hillside ♫ ♫ as they drove us ♫ ♫ from the Highlands ♫ ♫ Like the ice flow ♫ ♫ from the Arctic ♫ ♫ where we landed ♫ ♫ in Newfoundland ♫ ♫ There's a color ♫ ♫ to my sorrow ♫ ♫ There's a name for ♫ ♫ all this sadness ♫ ♫ Like the ocean ♫ ♫ in between us ♫ ♫ I am blue ♫ ♫ Blue is a river ♫ ♫...
(Music) (Applause) (Music) (Applause) Robbie Mizzone: Thank you. Tommy Mizzone: Thank you very much. We're so excited to be here. It's such an honor for us. Like he said, we're three brothers from New Jersey -- you know, the bluegrass capital of the world. (Laughter) We discovered bluegrass a few years ago, and we fell...
I'm a designer and an educator. I'm a multitasking person, and I push my students to fly through a very creative, multitasking design process. But how efficient is, really, this multitasking? Let's consider for a while the option of monotasking. A couple of examples. Look at that. This is my multitasking activity resul...
But anyway, this is about the evils of science, so I think it’s perfect. ♫ My oh my, walking by, who’s the apple of my eye? ♫ ♫ Why, it's my very own Clonie. ♫ ♫ Oh, if I should stroll the hood, who knew I could look so good ♫ ♫ just talking on the phone to Clonie. ♫ ♫ We are pals, it's cool, 'cause we're not lonely, ♫...
Basically, there's a major demographic event going on. And it may be that passing the 50 percent urban point is an economic tipping point. So the world now is a map of connectivity. It used to be that Paris and London and New York were the largest cities. What we have now is the end of the rise of the West. That's over...
I’m working a lot with motion and animation, and also I'm an old DJ and a musician. So, music videos are something that I always found interesting, but they always seem to be so reactive. So I was thinking, can you remove us as creators and try to make the music be the voice and have the animation following it? So with...
Forrest North: The beginning of any collaboration starts with a conversation. And I would like to share with you some of the bits of the conversation that we started with. I grew up in a log cabin in Washington state with too much time on my hands. Yves Behar: And in scenic Switzerland for me. FN: I always had a passio...
(Music) (Applause) (Applause) (Music) (Applause) (Music) (Applause) Chris Anderson: You guys were amazing. That's amazing. (Applause) You just don't hear that every day.

Well, I'm involved in other things, besides physics. In fact, mostly now in other things. One thing is distant relationships among human languages. And the professional, historical linguists in the U.S. and in Western Europe mostly try to stay away from any long-distance relationships, big groupings, groupings that go ...
(Music) ♫ I don't understand myself, ♫ ♫ why they keep talking of love, ♫ ♫ if they come near me, ♫ ♫ if they look into my eyes and kiss my hand. ♫ ♫ I don't understand myself, ♫ ♫ why they talk of magic, ♫ ♫ that no one withstands, ♫ ♫ if he sees me, if he passes by. ♫ ♫ But if the red light is on ♫ ♫ in the middle of...
(Music) (Applause) Thank you. Imagining a solo cello concert, one would most likely think of Johann Sebastian Bach unaccompanied cello suites. As a child studying these eternal masterpieces, Bach's music would intermingle with the singing voices of Muslim prayers from the neighboring Arab village of the northern Kibbut...

This means, "I'm smiling." So does that. This means "mouse." "Cat." Here we have a story. The start of the story, where this means guy, and that is a ponytail on a passer-by. Here's where it happens. These are when. This is a cassette tape the girl puts into her cassette-tape player. She wears it every day. It's not co...
The decorative use of wire in southern Africa dates back hundreds of years. But modernization actually brought communication and a whole new material, in the form of telephone wire. Rural to urban migration meant that newfound industrial materials started to replace hard-to-come-by natural grasses. So, here you can see...
At 7:45 a.m., I open the doors to a building dedicated to building, yet only breaks me down. I march down hallways cleaned up after me every day by regular janitors, but I never have the decency to honor their names. Lockers left open like teenage boys' mouths when teenage girls wear clothes that covers their insecurit...
In 2008, Cyclone Nargis devastated Myanmar. Millions of people were in severe need of help. The U.N. wanted to rush people and supplies to the area. But there were no maps, no maps of roads, no maps showing hospitals, no way for help to reach the cyclone victims. When we look at a map of Los Angeles or London, it is ha...
Imagine, if you will -- a gift. I'd like for you to picture it in your mind. It's not too big -- about the size of a golf ball. So envision what it looks like all wrapped up. But before I show you what's inside, I will tell you, it's going to do incredible things for you. It will bring all of your family together. You ...
This song is one of Thomas' favorites, called "What You Do with What You've Got." ♫ You must know someone like him ♫ ♫ He was tall and strong and lean ♫ ♫ With a body like a greyhound ♫ ♫ and a mind so sharp and keen ♫ ♫ But his heart, just like laurel ♫ ♫ grew twisted around itself ♫ ♫ Till almost everything he did ♫ ...
This is the exact moment that I started creating something called Tinkering School. Tinkering School is a place where kids can pick up sticks and hammers and other dangerous objects, and be trusted. Trusted not to hurt themselves, and trusted not to hurt others. Tinkering School doesn't follow a set curriculum, and the...
(Music) (Applause) Thank you. Hi, everybody. Ban-gap-seum-ni-da. I'd like to share with you a little bit of me playing my life. I might look successful and happy being in front of you today, but I once suffered from severe depression and was in total despair. The violin, which meant everything to me, became a grave bur...
Everything is interconnected. As a Shinnecock Indian, I was raised to know this. We are a small fishing tribe situated on the southeastern tip of Long Island near the town of Southampton in New York. When I was a little girl, my grandfather took me to sit outside in the sun on a hot summer day. There were no clouds in ...
When I was 14 years old, I had low self-esteem. I felt I was not talented at anything. One day, I bought a yo-yo. When I tried my first trick, it looked like this. I couldn't even do the simplest trick, but it was very natural for me, because I was not dextrous, and hated all sports. But after one week of practicing, m...
This is about a place in London called Kiteflyer's Hill where I used to go and spend hours going "When is he coming back? When is he coming back?" So this is another one dedicated to that guy ... who I've got over. But this is "Kiteflyer's Hill." It's a beautiful song written by a guy called Martin Evan, actually, for ...
Now, if President Obama invited me to be the next Czar of Mathematics, then I would have a suggestion for him that I think would vastly improve the mathematics education in this country. And it would be easy to implement and inexpensive. The mathematics curriculum that we have is based on a foundation of arithmetic and...
Has anyone ever been to Aspen, Colorado? It's not a joke yet; those aren't the jokes. Is this thing off? I went to Aspen recently and stumbled into this song. ♫ Black men go to Aspen ♫ ♫ and rent colorful chalets. ♫ ♫ Giggle at the questions ♫ ♫ their mere presence seems to raise. ♫ ♫ Get taken for men ♫ ♫ we don't res...
I've been playing TED for nearly a decade, and I've very rarely played any new songs of my own. And that was largely because there weren't any. (Laughter) So I've been busy with a couple of projects, and one of them was this: The Nutmeg. A 1930s ship's lifeboat, which I've been restoring in the garden of my beach house...
Humanity takes center stage at TED, but I would like to add a voice for the animals, whose bodies and minds and spirits shaped us. Some years ago, it was my good fortune to meet a tribal elder on an island not far from Vancouver. His name is Jimmy Smith, and he shared a story with me that is told among his people, who ...
How many of you love rhythm? Oh yeah, oh yeah. Oh yeah. (Cheers) (Drumming) I mean, I love all kinds of rhythm. I like to play jazz, a little funk, and hip hop, a little pop, a little R&B, a little Latin, African. And this groove right here, comes from the Crescent City, the old second line. (Cheers) Now, one thing all...
I collaborate with bacteria. And I'm about to show you some stop-motion footage that I made recently where you'll see bacteria accumulating minerals from their environment over the period of an hour. So what you're seeing here is the bacteria metabolizing, and as they do so they create an electrical charge. And this at...
I'm used to thinking of the TED audience as a wonderful collection of some of the most effective, intelligent, intellectual, savvy, worldly and innovative people in the world. And I think that's true. However, I also have reason to believe that many, if not most, of you are actually tying your shoes incorrectly. (Laugh...
Now, since this is TEDGlobal, who can tell me what this is called in French? I see you're all up on the history of hurdy-gurdy -- "vielle à roue." And in Spanish, "zanfona." And in Italian, "ghironda," okay? Hurdy-gurdy, or wheel fiddle. So, these are the different kinds and shapes of the hurdy-gurdy. The hurdy-gurdy i...

When I first arrived in beautiful Zimbabwe, it was difficult to understand that 35 percent of the population is HIV positive. It really wasn't until I was invited to the homes of people that I started to understand the human toll of the epidemic. For instance, this is Herbert with his grandmother. When I first met him,...
Imagine spending seven years at MIT and research laboratories, only to find out that you're a performance artist. (Laughter) I'm also a software engineer, and I make lots of different kinds of art with the computer. And I think the main thing that I'm interested in is trying to find a way of making the computer into a ...
Ladies and gentlemen, gather around. I would love to share with you a story. Once upon a time in 19th century Germany, there was the book. Now during this time, the book was the king of storytelling. It was venerable. It was ubiquitous. But it was a little bit boring. Because in its 400 years of existence, storytellers...

Today, I'm going to talk to you about sketching electronics. I'm, among several other things, an electrical engineer, and that means that I spend a good amount of time designing and building new pieces of technology, and more specifically designing and building electronics. And what I've found is that the process of de...
Five hundred seventy-one million two hundred thirty thousand pounds of paper towels are used by Americans every year. If we could -- correction, wrong figure -- 13 billion used every year. If we could reduce the usage of paper towels, one paper towel per person per day, 571,230,000 pounds of paper not used. We can do t...
A few years ago, my eyes were opened to the dark side of the construction industry. In 2006, young Qatari students took me to go and see the migrant worker camps. And since then I've followed the unfolding issue of worker rights. In the last six months, more than 300 skyscrapers in the UAE have been put on hold or canc...
I was a student in the '60s, a time of social upheaval and questioning, and -- on a personal level -- an awakening sense of idealism. The war in Vietnam was raging, the Civil Rights movement was under way and pictures had a powerful influence on me. Our political and military leaders were telling us one thing and photo...
As an artist, connection is very important to me. Through my work I'm trying to articulate that humans are not separate from nature and that everything is interconnected. I first went to Antarctica almost 10 years ago, where I saw my first icebergs. I was in awe. My heart beat fast, my head was dizzy, trying to compreh...
Great creativity. In times of need, we need great creativity. Discuss. Great creativity is astonishingly, absurdly, rationally, irrationally powerful. Great creativity can spread tolerance, champion freedom, make education seem like a bright idea. (Laughter) Great creativity can turn a spotlight on deprivation, or show...

Along the ancient path of the Monongahela River, Braddock, Pennsylvania sits in the eastern region of Allegheny County, approximately nine miles outside of Pittsburgh. An industrial suburb, Braddock is home to Andrew Carnegie's first steel mill, the Edgar Thomson Works. Operating since 1875, it is the last functioning ...
Today I'm going to show you an electric vehicle that weighs less than a bicycle, that you can carry with you anywhere, that you can charge off a normal wall outlet in 15 minutes, and you can run it for 1,000 kilometers on about a dollar of electricity. But when I say the word electric vehicle, people think about vehicl...
My travels to Afghanistan began many, many years ago on the eastern border of my country, my homeland, Poland. I was walking through the forests of my grandmother's tales. A land where every field hides a grave, where millions of people have been deported or killed in the 20th century. Behind the destruction, I found a...
Good afternoon. My name is Uldus. I am a photo-based artist from Russia. I started my way around six years ago with ironic self-portraits to lay open so many stereotypes about nationalities, genders, and social issues — ["I am Russian. I sell drugs, guns, porno with kids!"] ["Vodka = water. I love vodka!"] (Laughter) —...
Why grow homes? Because we can. Right now, America is in an unremitting state of trauma. And there's a cause for that, all right. We've got McPeople, McCars, McHouses. As an architect, I have to confront something like this. So what's a technology that will allow us to make ginormous houses? Well, it's been around for ...
It's great being here at TED. You know, I think there might be some presentations that will go over my head, but the most amazing concepts are the ones that go right under my feet. The little things in life, sometimes that we forget about, like pollination, that we take for granted. And you can't tell the story about p...
Organic chemists make molecules, very complicated molecules, by chopping up a big molecule into small molecules and reverse engineering. And as a chemist, one of the things I wanted to ask my research group a couple of years ago is, could we make a really cool universal chemistry set? In essence, could we "app" chemist...
We are drowning in news. Reuters alone puts out three and a half million news stories a year. That's just one source. My question is: How many of those stories are actually going to matter in the long run? That's the idea behind The Long News. It's a project by The Long Now Foundation, which was founded by TEDsters inc...
Let me introduce to you Rezero. This little fellow was developed by a group of 10 undergraduate students at the Autonomous Systems Laboratory at ETH-Zurich.

A few years ago, I felt like I was stuck in a rut, so I decided to follow in the footsteps of the great American philosopher, Morgan Spurlock, and try something new for 30 days. The idea is actually pretty simple. Think about something you've always wanted to add to your life and try it for the next 30 days. It turns o...
Ladies and gentlemen, at TED we talk a lot about leadership and how to make a movement. So let's watch a movement happen, start to finish, in under three minutes and dissect some lessons from it.

Two years ago here at TED I reported that we had discovered at Saturn, with the Cassini Spacecraft, an anomalously warm and geologically active region at the southern tip of the small Saturnine moon Enceladus, seen here. This region seen here for the first time in the Cassini image taken in 2005. This is the south pola...
So, imagine you're standing on a street anywhere in America and a Japanese man comes up to you and says, "Excuse me, what is the name of this block?" And you say, "I'm sorry, well, this is Oak Street, that's Elm Street. This is 26th, that's 27th." He says, "OK, but what is the name of that block?" You say, "Well, block...
Thank you very much. Now, I've got a story for you. When I arrived off the plane, after a very long journey from the West of England, my computer, my beloved laptop, had gone mad, and had -- oh! -- a bit like that! -- and the display on it -- anyway, the whole thing had burst. And I went to the IT guys here and a gentl...

So my name is Taylor Wilson. I am 17 years old and I am a nuclear physicist, which may be a little hard to believe, but I am. And I would like to make the case that nuclear fusion will be that point, that the bridge that T. Boone Pickens talked about will get us to. So nuclear fusion is our energy future. And the secon...
I used to be a Malthusian. This was my mental model of the world: exploding population, small planet; it's going to lead to ugly things. But I'm moving past Malthus, because I think that we just might be about 150 years from a kind of new enlightenment. Here's why. This is the U.N.'s population data, you may have seen,...
I’d like to dedicate this next song to Carmelo, who was put to sleep a couple of days ago, because he got too old.

About a year ago, I asked myself a question: "Knowing what I know, why am I not a vegetarian?" After all, I'm one of the green guys: I grew up with hippie parents in a log cabin. I started a site called TreeHugger -- I care about this stuff. I knew that eating a mere hamburger a day can increase my risk of dying by a t...
You know, what I do is write for children, and I'm probably America's most widely read children's author, in fact. And I always tell people that I don't want to show up looking like a scientist. You can have me as a farmer, or in leathers, and no one has ever chose farmer. I'm here today to talk to you about circles an...
I don't know if you've noticed, but there's been a spate of books that have come out lately contemplating or speculating on the cognition and emotional life of dogs. Do they think, do they feel and, if so, how? So this afternoon, in my limited time, I wanted to take the guesswork out of a lot of that by introducing you...

From all outward appearances, John had everything going for him. He had just signed the contract to sell his New York apartment at a six-figure profit, and he'd only owned it for five years. The school where he graduated from with his master's had just offered him a teaching appointment, which meant not only a salary, ...
How does the news shape the way we see the world? Here's the world based on the way it looks -- based on landmass. And here's how news shapes what Americans see. This map -- (Applause) -- this map shows the number of seconds that American network and cable news organizations dedicated to news stories, by country, in Fe...
When I turned 19, I started my career as the first female photojournalist in the Gaza Strip, Palestine. My work as a woman photographer was considered a serious insult to local traditions, and created a lasting stigma for me and my family. The male-dominated field made my presence unwelcome by all possible means. They ...
I have the answer to a question that we've all asked. The question is, Why is it that the letter X represents the unknown? Now I know we learned that in math class, but now it's everywhere in the culture -- The X prize, the X-Files, Project X, TEDx. Where'd that come from? About six years ago I decided that I would lea...
Let's talk about manias. Let's start with Beatle mania: hysterical teenagers, crying, screaming, pandemonium. Sports mania: deafening crowds, all for one idea -- get the ball in the net. Okay, religious mania: there's rapture, there's weeping, there's visions. Manias can be good. Manias can be alarming. Or manias can b...
As a boy, I loved cars. When I turned 18, I lost my best friend to a car accident. Like this. And then I decided I'd dedicate my life to saving one million people every year. Now I haven't succeeded, so this is just a progress report, but I'm here to tell you a little bit about self-driving cars. I saw the concept firs...
Fifty years ago in the old Soviet Union, a team of engineers was secretly moving a large object through a desolate countryside. With it, they were hoping to capture the minds of people everywhere by being the first to conquer outer space. The rocket was huge. And packed in its nose was a silver ball with two radios ins...

Photography has been my passion ever since I was old enough to pick up a camera, but today I want to share with you the 15 most treasured photos of mine, and I didn't take any of them.

It is a dream of mankind to fly like a bird. Birds are very agile. They fly, not with rotating components, so they fly only by flapping their wings.

Cholera was reported in Haiti for the first time in over 50 years last October. There was no way to predict how far it would spread through water supplies and how bad the situation would get.
