Measuring the Speed of Quantum Tunneling
Chad Orzel, Forbes
I've been wrapped up in writing a new book, so I didn't notice this right when it was published, but a couple of weeks ago there was a paper in Physical Review Letters titled Experimental Evidence for Quantum Tunneling Time that's worth a mention here. This is, as the title suggests, an investigation of one of the signature weird effects of quantum physics, namely the phenomenon of "tunneling" where a particle encountering a barrier can end up on the other side even though it doesn't have enough energy to get there by normal means.
