Why do electrical clocks drift and why are atomic clocks more accurate and don't drift as much?

I know some use vibrating quartz. Are the vibrations just not measured accurately or is it something to do with the quartz? Any other thing you can think about this subject would be cool, or if you know of a good lecture/talk about it. Anyways thanks for taking the time to read.

"Electrical Clocks" drift as the frequency of the used oscillator is only known to some precision. Even a drift of a few ppm will cause a noticable drift over time, as most oscillators for clocks have frequencys of 32kHz and above. Of course one can measure the actuall frequency to a very good precision, but then you have to look out for problem with temperature stability, vibration and other sources of errors. Basically with changing temperature the frequency changes.

Atomic clocks don't use some physical structure that osciallates in some manner, but count the osciallation of atoms, which don't depend on the surroundings and are therefore several magnitudes more precise.
