Uncertainty principle scaled up to visible size

[sir pball]

1. Hmm

I left my copy of Atkins (my physical chemistry textbook) in another life, but something about this doesn't sit quite right with me in terms of the actual definitions of the uncertainty principle in terms of the mathematical relationships between momentum and position, as opposed to the essentially thought-experiment example of bouncing photons. This feels more like simple resonance to me...but I haven't sat down with my books in ten years so I could be completely off the mark.
