This femtosecond stuff is awesome. Incidentally, femtosecond lasers are now widely used in chemistry for time-resolved spectroscopy. All kinds of neat stuff happens in the time domain, and it's only fairly recently that we can examine it.
Even crazier than femto- stuff, though, is zepto- (that's 10-21). I talked to a neurochemist at Chapel Hill who talked about measuring the concentration of neurotransmitters and such in the range of zeptomoles. That's freaking ludicrous.
