However, you might not expect it to be at the cutting edge of the mind-bending world of quantum physics. But on Tuesday, David Wineland became the fourth employee at the National Institute for Standards and Technology, a federal lab, to win a Nobel since 1997. Wineland learned he will share the Nobel Prize in physics with Frenchman Serge Haroche for work that's both esoteric and practical.
