“Is there a reason for governments to be in charge of money?” asks Paul Kemp-Robertson in today’s talk. Judging by the new raft of alternative currencies—from digital coins to point systems that reward customers of a certain brand—the answer might someday be “no.” Again. As Kemp-Robertson suggests, many people seem to trust brands more than […]
It’s an alchemic question that’s very hard for us to answer: what makes a great TED talk? In this talk, which was given to a gathering of 100+ TEDx organizers from 43 countries during the TEDx Workshop at TEDGlobal 2013, our curator Chris Anderson stresses the incredible power of a well-structured, honest talk. “We’re giving someone […]
When Roberto D’Angelo and Francesca Fideli discovered that their 10-day-old son, Mario, had suffered a stroke, they were shocked. Maria was unable to control the left side of his body and, to help their son, they opted to participate in a pilot program for mirror neuron rehabilitation. As they explain in the talk, mirror neuron […]
Illusionist Marco Tempest (watch his cyber card trick and his electric take on Nikola Tesla) has a new assistant — Baxter the Robot. The star of this talk from roboticist Rodney Brooks, Baxter is a life-sized robot that has eyes that glance where he is about to move and arms that react to human touch, […]
John Searle studies consciousness — which, as he points out in today’s talk, is a “curiously neglected subject in our scientific and philosophical culture.” Curiously — because it is, after all, a pre-condition for anything else we think about. And yet neglected — because consciousness is a subject that makes scientists huffy (they see it […]
On July 20, 1969, Neil Armstrong became the first human to walk on the moon. Moon Day is held every July 20 to commemorate this momentous feat. 43 years later, humanity is still looking to the sky, mesmerized by lunar bodies. However, it is not just Earth’s moon we’re studying anymore. With better satellites and […]
Some chewy food for thought this week on the Internets: The host of the blog Ask a Korean! responds to a chapter in Malcolm Gladwell’s Outliers that links culture to frequency of plane crashes. (Watch an unrelated talk from Gladwell here.) Read the original post here and some updates here, which includes Gladwell’s response to […]
Biologist, poet and fledgling entrepreneur Ivana Gadjanski has worked on using animal toxins as a possible treatment for MS, and is growing bones and cartilage in dishes. She has also published two books of poetry in Serbia. Now she’s developing Pubsonic, an online research tool that allows users to access free medical journal papers via […]
Today may go down in history as The Day the Earth Smiled. Or, at least, that is what TED speaker Carolyn Porco (watch her talk) is hoping. Today from 9:27 to 9:42 pm GMT, the Cassini spaceship — an unmanned ship studying Saturn — will be taking a photograph of Saturn and its ring system. And […]
In 2007, journalist Andrew Mwenda took the stage at TEDGlobal in Arusha, Tanzania, and decried the symptomatic disease affecting his home continent: aid. The surprising take certainly got the goat of some members of the audience, including U2 frontman Bono, who has devoted so much time to promoting the need for African aid and who […]
When you think of bacteria, the word ‘heroic’ hardly pops to mind. Bacteria don’t have the best reputation (case in point: the poop problem). 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 […]
In today’s talk, Pico Iyer looks at the complexity of the question, “Where do you come from?” If the question is code for, “Where are your family’s roots?” his answer is India — although he has never lived there. 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.) Meanwhile, back at US headquarters, as NSA officials speak in a House Judiciary Committee hearing, the agency is still doing what it’s doing. To get more information on exactly what […]
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. As soon as he left school, however, he moved to the United States — where he was required to carry a […]
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 […]
