comment Is fluorescence from a single atom/ion visible with the naked eye (e.g. in a strongly coupled trap or cavity)
Given that that image has multiple different intensities spread across multiple pixels, it clearly involved many photons. Are you asking about just a single photon at a time? Are you asking about the rate at which these photons are emitted (equivalently what the exposure time must have been)?

comment Beads flying out of flask
Indeed. And the converse of the last statement also holds: If you put all the laws of physics into your computer and run a perfect simulation that's correct in every detail without worrying about approximations or such, then have you really learned anything at all?
