In Al Gore’s brand-new slideshow (premiering exclusively on TED.com), he presents evidence that the pace of climate change may be even worse than scientists were recently predicting, and challenges us to act with a sense of “generational mission” — the kind of feeling that brought forth the civil rights movement — to set it right. Gore’s stirring presentation is followed by a brief Q&A in which he is asked for his verdict on the current political candidates’ climate policies and on what role he himself might play in future....

http://www.ted.com Clifford Stoll could talk about the atmosphere of Jupiter. Or hunting KGB hackers. Or Klein bottles, computers in classrooms, the future. But he’s not going to. Which is fine, because it would be criminal to confine a man with interests as multifarious as Stoll’s to give a talk on any one topic. Instead, he simply captivates his audience with a wildly energetic sprinkling of anecdotes, observations, asides — and even a science experiment. After all, by his own definition, he’s a scientist: “Once I do something, I want to do something else.”... Read More إقرأ المزيد | Share it now!

http://www.ted.com – Accepting his 2008 TED Prize, physicist Neil Turok speaks out for talented young Africans starved of opportunity: by unlocking and nurturing the continent’s creative potential, we can create a change in Africa’s future. Turok asks the TED community to help him expand the African Institute for Mathematical Sciences by opening 15 new centers across Africa in five years. By adding resources for entrepreneurship to this proven model, he says, we can create a network for progress across the continent — and perhaps discover an African Einstein....
