Neil DeGrasse Tyson discusses Death by Black Hole .
Whether discussing the universe’s origins as host of NOVA’s “scienceNOW” or asserting that Pluto is a not a planet on “The Colbert Report,” astrophysicist Neil deGrasse Tyson translates the universe’s complexities for a broad audience.
Known as the great explainer of all things cosmic, Tyson first became known in the astronomy community by lecturing on the subject at the age of fifteen. He is currently the director of New York’s Hayden Planetarium at the American Museum of Natural History, where he also teaches. Tyson has written seven popular books including the bestselling Death by Black Hole and the memoir The Sky Is Not The Limit.
His professional research explores star formation, dwarf galaxies, exploding stars, and the structure of the Milky Way, topics which he writes about in his long running “Universe” column in Natural History magazine. Tyson’s varied honors include the NASA Distinguished Public Service Medal and People Magazine’s 2000 “Sexiest Astrophysicist Alive” – City Arts & Lectures
Carnegie Mellon professor and ex-imagineer Jesse Schell lays out a vision of the future in which our lives become, essentially, one big RPG. Schell’s discussion kicks off with some of the most unexpected gaming developments over the last few years.
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.
Temple Grandin, diagnosed with autism as a child, talks about how her mind works — sharing her ability to “think in pictures,” which helps her solve problems that neurotypical brains might miss. She makes the case that the world needs people on the autism spectrum: visual thinkers, pattern thinkers, verbal thinkers, and all kinds of smart geeky kids.
Sharing powerful stories from his anti-obesity project in Huntington, W. Va., TED Prize winner Jamie Oliver makes the case for an all-out assault on our ignorance of food.
Anthony Atala's state-of-the-art lab grows human organs — from muscles to blood vessels to bladders, and more. At TEDMED, he shows footage of his bio-engineers working with some of its sci-fi gizmos, including an oven-like bioreactor (preheat to 98.6 F) and a machine that “prints” human tissue.
In this highly personal talk from TEDMED, magician and stuntman David Blaine describes what it took to hold his breath underwater for 17 minutes — a world record (only two minutes shorter than this entire talk!) — and what his often death-defying work means to him. Warning: do NOT try this at home.
