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.”
What’s it like to be pals with a genius? Onstage at TEDxCaltech, physicist Leonard Susskind spins a few stories about his friendship with the legendary Richard Feynman, discussing his unconventional approach to problems both serious and … less so.

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 →
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 →
At TED2010, Bill Gates unveils his vision for the world’s energy future, describing the need for “miracles” to avoid planetary catastrophe and explaining why he’s backing a dramatically different type of nuclear reactor. The necessary goal? Zero carbon emissions globally by 2050.
En TED2010, Bill Gates presenta su visión para el futuro mundial de la energía, describiendo la necesidad de ‘milagros’ para evitar la catastrofe planetaria y explicando porque está respaldando un tipo de reactor nuclear dramáticamente distinto. La meta necesaria: Cero emisiones globales de carbón para el año 2050.Sigue leyendo →
Recientemente, investigadores de la Universidad Politécnica de Valencia han publicado un artículo en la revista “Mathematical and Computer Modelling”, en el que se describe un modelo destinado a la estimación de los niveles de vibración obtenidos en el entorno a partir de la zona de interacción rueda-carril.

Is our response to music hard-wired or culturally determined? Is the reaction to rhythm and melody universal or influenced by environment? John Schaefer, scientist Daniel Levitin, and musical artist Bobby McFerrin engage in live performances and cross-cultural demonstrations to illustrate music’s noteworthy interaction with the brain and our emotions.

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 →
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.
