We've made incredible advances in technology in recent years, but too often it seems only certain fortunate people can benefit. Engineer Krista Donaldson introduces the ReMotion knee, a prosthetic device for above-knee amputees, many of whom earn less than $4 a day. The design contains best-in-class technology and yet is far cheaper than other p...

Child prodigy Adora Svitak says the world needs "childish" thinking: bold ideas, wild creativity and especially optimism. Kids' big dreams deserve high expectations, she says, starting with grownups' willingness to learn from children as much as to teach.

When Bran Ferren was just 9, his parents took him to see the Pantheon in Rome — and it changed everything.

TED Resident Keith Kirkland and his team at WearWorks use haptic technology to develop products and experiences that communicate information through touch. In 2017, they were faced with a seemingly impossible challenge: quickly develop a device for a blind ultra-marathon runner to compete -- unaided and unassisted -- in the New York City Maratho...

About this event: The essence of design is thinking made visual. From traditional craft to computer design, from dress design to app design...they are all processes of thought becoming reality in a nexus of creativity. By breaking out of established patterns of thinking and doing, by tapping into our inner child and by not fearing failure, we can pierce the ordi...

Prosthetics can't replicate the look and feel of lost limbs but they can carry a lot of personality. Designer Scott Summit shows 3D-printed, individually designed prosthetic legs that are unabashedly artificial and completely personal -- from macho to fabulous.

About this event: There is so much that happens around us that is invisible. The influences of culture, politics, body language, neuroscience, feelings... all these seem invisible. But there is also the other type of invisible, being invisible in a room full of people, in a school full of children, in a book full of faces. This invisibility has profound effects o...

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...

More than half of the world's population already lives in cities, and another 2.5 billion people are projected to move to urban areas by 2050.

Peter Calthorpe is already at work pla...

A third of the world watched live as the World Trade Center collapsed on September 11, 2001; a third more heard about it within 24 hours. (Do you remember where you were?)
