<<finer tuned our instruments>>

If you narrow the slit on a spectrograph, further fine structures will at some point STOP being visible at any higher level of resolution because of the intrinsic uncertainty of an electron orbiting the atom. However, with femtosecond lasers you can address a single electron - almost like calling it by name.

The wife and I just watched a DVD of the SciFi channel production of Ursula Le Guin's Earthsea saga. One of the cool things in that is everything has its "secret name" from which it derives its power. Even a grain of sand. Femtosecond pulses allow observers to find the secret "name" of each electron so, in theory, you could watch the motion of a single gas atom or molecule.
