I’ve been a reader of Roger Ebert’s blog since he started writing it. Most of his posts are about as profound as it gets. Reading his stories ranging in diversity from his own history and childhood to the loneliness of isolation he feels from those that leave comments on his blog, one is left with little doubt why the famous critic was drawn to journalism — he’s an amazing writer.
When he lost his lower jaw to cancer in 2006, he lost the ability to eat and speak. However, he certainly didn’t lose his voice. In this moving talk from TED2011, Ebert and his wife, Chaz, with friends Dean Ornish and John Hunter, come together to tell his remarkable story.
Biologist Robert Full explains how bio-mimicry not only teaches us how to make better robots but also helps us to better understand the world around us. Case in point, while investigating how to replicate gecko feet and in turn to make a gecko robot, Full’s team discovered that the machine didn’t operate well without a tail. When his team asked Full what was the purpose of the gecko’s tail, to his surprise, he wasnâ€™t quite sure, so he set out to investigate. He discovered an entire universe of surprises, which he describes in this TED talk.
Listen to Dan Ariely’s talk, presented in February 2009 at the TED conference, about his experiments in predictable irrationality. He explains how bugs in our moral code make us think it’s okay to cheat or steal sometimes but not others.
Theo Jansen invents incredible mechanical creatures, or new kinds of life, as he likes to say. He presented them at TED.
This CGI reconstruction demonstrates the principle behind these walking creatures:
Some intrepid designers at the University of Louisiana have taken the idea and created a kind of walking Segway, they’ve named it the Cajun Crawler:
The scooter was inspired by Theo Jansen’s leg mechanism. Throughout our research, we found no application where Jansen’s leg mechanism was used as a weight-bearing application or vehicle. The legs are made of standard 5052 Aluminum. The joints all contain deep-groove ball bearings.
No flying cars yet, but the future is just about here. Check out this amazing device that only costs around $350 for the partsâ€”itâ€™s basically a camera, projector and smart phone interacting with the world around us.
Steven Levitt, of Freakonomics fame, at a 2005 TED Talk speaks about the economics of car seats. His data lead him to ask the morally difficult question, are childrenâ€™s car seats worth the time and expense it takes to use them?
I just watched Dave Eggers TED talk about the 826 Valencia project. Itâ€™s inspiring and funny; please enjoy:
Accepting his 2008 TED Prize, author Dave Eggers asks the TED community to personally, creatively engage with local public schools. With spellbinding eagerness, he talks about how his 826 Valencia tutoring center inspired others around the world to open their own volunteer-driven, wildly creative writing labs. But you donâ€™t need to go that far, he reminds usâ€”itâ€™s as simple as asking a teacher â€œHow can I help?â€ He asks that we share our own volunteering stories at his new website, Once Upon a School.
This remarkable video shows a glimpse into the fascinating world of the ant. The narrator describes the intricate ant nest as an accomplishment equivalent to the building of the great wall of China.
The structure covers 538 square feet and travels 26 feet into the earth. In itâ€™s construction, the colony moved 40 tons of soil. Billions of ant loads of soil were brought to the surface. Each load weighed four times as much as the worker ant, and in human terms, was carried over 1/2 mile to the surface.
