A 40-year plan for energy - Amory Lovins - View full lesson: http://ed.ted.com/lessons/a-40-year-p...
In this intimate talk filmed at TED's offices, energy innovator Amory Lovins shows how to get the US off oil and coal by 2050, $5 trillion cheaper, with no Act of Congress, led by business for profit. The key is integrating all four energy-using sectors—and four kinds of innovation.

Why Are Revolutionary Scientists Young? - Einstein, Newton, Darwin, and Hawking are just some of the young scientists that have profoundly shaped science. Why is youth a key element in a revolutionary scientist. Note: this vlog contains a fair deal of conjecture. I invite healthy discussion and debate.

Michael Dickinson: How a fly flies - An insect's ability to fly is perhaps one of the greatest feats of evolution. Michael Dickinson looks at how a common housefly takes flight with such delicate wings, thanks to a clever flapping motion and flight muscles that are both powerful and nimble. But the secret ingredient: the incredible fly brain. (Filmed at TEDxCaltech.)
Lee Cronin: Print your own medicine
Chemist Lee Cronin is working on a 3D printer that, instead of objects, is able to print molecules. An exciting potential long-term application: printing your own medicine using chemical inks.

SciShow Talk Show! Peter, Self-healing Skin, & Professor Claw the Emperor Scorpion - Featuring Peter Winkler, our SciShow graphics guru, and Professor Claw, the emperor scorpion. We decided it would be cool to have guests come into the studio and talk about science with Hank.
In this episode, Peter and Hank discuss the science of prosthetic skin and Saturn's rings. Then Jessi from Animal Wonders introduces Professor Claw, the emperor scorpion and Hank debates how cool it is to get stung by a scorpion
Tyler DeWitt: Hey science teachers -- make it fun - High school science teacher Tyler DeWitt was ecstatic about a lesson plan on bacteria (how cool!) -- and devastated when his students hated it. The problem was the textbook: it was impossible to understand. He delivers a rousing call for science teachers to ditch the jargon and extreme precision, and instead make science sing through stories and demonstrations. (Filmed at TEDxBeaconStreet.)
