From envying comic book characters to pondering extra dimensions while staring at fish, Dr. Michio Kaku recounts the experiences that made him one of the world's most colorful scientists.
Propelling a spaceship with photons would be like trying to energize a spaceship with a flashlight.
In the 1999 film "The Matrix," characters could simply learn a new set of skills by uploading a program into their brains. When (if ever) will we be able to that in real life?
Einstein believed that free will was just an illusion, and that awareness of this lack kept him from taking himself and others too seriously. But Einstein was plain wrong, says Dr. Kaku.
The physicist scoffed at the idea of quantum entanglement, calling it "spooky action at a distance." And while it has in fact been proven to exist, this entanglement can't be used to transmit any usable information.
The physicist sees two major trends in the world today: the first is toward a multicultural, scientific, tolerant society; the other, as evidenced by terrorism, is fundamentalist and monocultural. Whichever one wins out will determine the fate of man
El físico Michio Kaku considera que hay dos grandes tendencias en el mundo actual: la primera es hacia una sociedad multicultural, la sociedad científica, tolerante, y el otro, como lo demuestra el terrorismo, es fundamentalista y monocultural. Cualquiera que sea la gana uno determinará el destino del hombre
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."
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.
