The World's Smallest Double Slit Experiment: Breaking up the Hydrogen Molecule (11/12/2007)

The big world of classical physics mostly seems sensible: waves are waves and particles are particles, and the moon rises whether anyone watches or not. The tiny quantum world is different: particles are waves (and vice versa), and quantum systems remain in a state of multiple possibilities until they are measured â€" which amounts to an intrusion by an observer from the big world â€" and forced to choose: the exact position or momentum of an electron, say. ...> Full Article
