Innovation chief says “pressure test” your pet hypothesis. It’s guaranteed to be wrong.
His grandfather, a member of Oppenheimer’s atomic bomb team, foresaw the potential of nuclear energy to power cities – not destroy them. Today, Astro Teller is on a mission to harness innovation for good. Here’s how he’s doing it.
How the world’s most sensitive yardstick reveals secrets of the universe
When two massive objects – like black holes or neutron stars – merge, they warp space and time. Here's the tool that measures the resulting waves.
