Speakers Richard Feynman: Physicist

One of the best known and most renowned scientists in history, Richard Feynman pioneered quantum mechanics. His knack for accessible explanations made him a popularizer of physics of equal distinction to laypeople.

Why you should listen to him?

Richard Feynman began his career at a crossroads in history, assisting the Manhattan Project with the development of the atomic bomb. Soon he was producing breakthrough understandings of particle physics and quantum mechanics, for which he won the Nobel Prize in 1965. His pictorial representations of the actions of subatomic particles are still widely used today (they’re now called Feynman diagrams).

Feynman acted as an adviser on the commission investigating the space shuttle Challenger disaster. Books based on his lectures and conversations became best-sellers, and cemented him in the public mind as an explainer of science. He was a legendary prankster, a charismatic free-thinker and an avid bongoist.

“At twenty-three … there was no physicist on earth who could match his exuberant command over the native materials of theoretical science. […] Feynman seemed to possess a frightening ease with the substance behind the equations, like Albert Einstein at the same age, like the Soviet physicist Lev Landau — but few others.”

TED – El ambicioso plan de Shai Agassi para autos eléctricos / Shai Agassi’s bold plan for electric cars

[Visto: 2269 veces]

Forget about the hybrid auto — Shai Agassi says it’s electric cars or bust if we want to impact emissions. His company, Better Place, has a radical plan to take entire countries oil-free by 2020.

About Shai Agassi

Shai Agassi wants to put you behind the wheel of an electric car — but he doesn’t want you to sacrifice convenience (or cash) to do it.

Olvidense de los automóviles híbridos. Shai Agassi dice que si queremos reducir las emisiones de CO2, son los autos eléctricos o nada. Su compañía, Better Place, tiene un plan radical para convertir a varios países en libres de petróleo para el 2020. Sigue leyendo

TED – Larry Burns on the future of cars / Larry Burns sobre el futuro de los automóviles

[Visto: 2386 veces]

General Motors veep Larry Burns previews cool next-gen car design: sleek, customizable (and computer-enhanced) vehicles that run clean on hydrogen — and pump energy back into the electrical grid when they’re idle.

About Larry Burns

Larry Burns is the vice president of R&D for GM. His job? Find a new way to power cars

Larry Burns, VP de General Motors nos da una muestra del diseño de coches de próxima generación: vehículos impecables, presonalizables (mejorados por ordenador) que funcionan de forma más limpia con hidrógeno (y bombean energía de vuelta a la red electrica cuando están en reposo). Sigue leyendo

TED / Bill Gates on energy: Innovating to zero! / Bill Gates sobre la energía: ¡Innovando hacia cero!

About This Video

Astronauts who’ve lived on the International Space Station and “walked” in space tell all: what it’s like to ride on a space ship, and to eat, sleep, exercise, and even do science—in space. Hear firsthand from the world’s most intrepid explorers—including astronauts Tracy Caldwell Dyson, Leland Melvin, and Sandra Magnus—and Dava Newman, designer of an innovative spacewalking suit, about what it’s like to soar upward and leave our home, planet Earth, behind. Journalist Miles O’Brien moderates. Sigue leyendo

World Science Festival 2010 / Good Vibrations: The Science of Sound

About This Video

We look around us—constantly. But how often do we listen around us? Sound is critically important to our bodies and brains, and to the wider natural world. In the womb, we hear before we see. John Schaefer, Jamshed Bharucha, Christopher Shera, the Danish sound artist Jacob Kirkegaard, and multi-instrumentalists Polygraph Lounge embark on a fascinating journey through the nature of sound. How we perceive it, how it acts upon us, and how it profoundly affects our well-being—including a demonstration of sounds produced by sources as varied as the human inner ear and the creation of the universe itself.
