Filmmaker David Hoffman shares footage from his feature-length documentary Sputnik Mania, which shows how the Soviet Union's launch of Sputnik in 1957 led to both the space race and the arms race -- and jump-started science and math education around the world.

Nine days before TED2008, filmmaker David Hoffman lost almost everything he owned in a fire that destroyed his home, office and 30 years of passionate collecting. He looks back at a life that's been wiped clean in an instant -- and looks forward.
