Uncertainty at a grand scale
Macro test of Heisenberg’s principle may aid hunt for gravitational waves
By Andrew Grant, 12:59 PM February 14, 2013
The Heisenberg uncertainty principle, a tenet of quantum mechanics, has been demonstrated at scales visible to the naked eye. The research, described in the Feb. 15 Science, could help scientists detect minuscule perturbations in the fabric of space caused by merging black holes.
“The uncertainty principle has been demonstrated in many different ways, but to see it on a visible mechanical object is totally awesome,” says Keith Schwab, a physicist at Caltech who was not involved in the resea...
