Another interesting related topic:
Scientists have been pushing the limits in trying to make the shortest pulse of light possible. They think that it may be possible, with good fortune, that a pulse of light can be made which is shorter in duration than the predicted orbit times of electrons in certain atoms (probably larger ones with longer orbital times, not hydrogen), and take a "picture" of sorts to see if an electron or proton has a definite position with time. They'd probably get a blur, and it wouldn't really be an image in the conventional sense. They think they can get one pulse down to the orbital time of one electron around a hydrogen nucleus. It was a funny unit of time, like 22 yoctoseconds, don't count on my being completely correct.  From what I remember, the shortest pulse was about two wavelengths, of whatever wavelength of light they were working with. Hopefully it wasn't shortwave. I imagine it was of a visible wavelength or less. Might be something interesting to look up.
