Quantum weirdness

I’m a little late getting this news, but I’m fascinated by an experiment at Australian National University showing (once again) in a vivid way how strange the quantum mechanical world is. The experiment was a variation on the celebrated double slit experiment that shows how photons are both particles and waves, at least in some interpretations of the universe. That’s freakish in a not-news kind of way, as is the fact that the same is true of good old atoms, which might seem more as though they should stay particular all the time.
