Wired News has info on a new attempt to test the limits of quantum physics:

“The experiment will be the first time scientists have ever scaled an object in the observable world down into the slippery world of quantum mechanics.

‘I think it’s really possible to observe quantum effects (in the cantilever arm) with this experiment,’ said Peter Rabl of the University of Innsbruck in Austria, who isn’t part of the experiment.

‘Either you have a real, macroscopic object in a quantum state — or you find out that quantum mechanics doesn’t work for the macroscopic world,’ he said. ‘In either case, it would be quite fascinating.'”

The article goes on to claim that this would be the first direct observation of quantum effects if it works. There was a news a few years ago though of a direct observation of quantum tunneling.

My intuition says that the quantum effect will show – but I’ve learned that when it comes to quantum physics to not trust my instincts… I guess I’m a macroscopic kinda guy at heart… Grin.
