But, we are reminded in today’s talk, from teen scientists Miranda Wang and Jeanny Yao, that not all bacteria are our enemies. Wang and Yao found themselves faced with an immovable […]

If the question means, “Where were you born?” his answer is England — though he left […]
As Edward Snowden is linked to one country after the next, the media has its eye fixed on where he will next request asylum. (Today, it’s Russia.)

In today’s thought-provoking talk, author Pico Iyer looks at the complex nature of the simple question: “Where are you from?” Because while his family comes from India, he grew up in the United Kingdom.

The Cloud Appreciation Society may be the first official organization to celebrate the beauty of clouds, but these fluffy pillows in the sky have been a source of fascination since 3,000 B.C., when they were first discussed in the Upanishads. Aristotle poetically described cloud formation in his 350 B.C. work Meteorology as the process by […]
A “cloud on the horizon” means that something bad is about to happen. Meanwhile, someone with their “head in the clouds” is thoroughly out to lunch. As Gavin Pretor-Pinney points out in today’s talk, clouds get a bad rep when it comes to language. “But I think they’re beautiful, don’t you?” he says. “It’s just […]
Like so many people in the United States, we were shocked by George Zimmerman’s acquittal this weekend in the shooting of teenager Trayvon Martin, above.

“Let us wage a glorious struggle against illiteracy, poverty and terrorism. Let us pick up our books and our pens, and let us shield ourselves with unity and togetherness.” These were the words spoken by 16-year-old Malala Yousafzai, above, the Pakistani schoolgirl who was shot in the head by a Taliban gunman in 2012 for […]
There are thousands of faces in the skyscraper windows in this anime-inspired 3D music video. Each face is a webcam capture of a singer — 5,905 of them to be exact, from 101 countries across the globe.

When recording music, it can take days or weeks to get the perfect performances for an album. But when it comes to recording the symphony of nature, the process can take even longer.

Today’s talk, which posits a fascinating metaphor for sex beyond baseball, comes from a passionate and dedicated sexuality educator. Al Vernacchio teaches his students that it’s not just getting the facts right that counts, but understanding the nuances of human sexuality and its place in society. Inspired by the teaching philosophy that Vernacchio brings to […]
Editor’s note: In today’s talk, Al Vernacchio offers a new metaphor for thinking about sex — ordering a pizza. Outside of his Philadelphia-area classroom, where he works as a sexuality educator for high-school students, Vernacchio also serves as a marriage officiant. With weddings on our minds this summer, we asked him to share his thoughts on […]

Twenty-four years later, […]
Colorblind artist Neil Harbisson is an intrepid “eyeborg” wearer. That’s a device that converts color into audible frequencies, meaning that Harbisson gets to hear a symphony of color, instead of seeing a world only in grayscale. Below, Harbisson’s talk from TEDGlobal 2012 gets the graphic treatment in a beautiful chart that shows precisely which colors sound which musical notes for him. This is […]
[ted id=1482] Nikola Tesla, named by The Oatmeal the “greatest geek who ever lived,” was born on this day in 1856.

Michael Pritchard is very likely the only person to have stood on the TED stage and uttered the immortal phrase, “Let’s get a bit of that poo in there.” At TEDGlobal 2009 in Oxford, he demonstrated his then-new product, the Lifesaver bottle, which can be used to turn filthy, rabbit-dropping-infested water into sparklingly clean liquid […]
