Re: Physics Discussion Thread

Is it possible to calibrate a more precise instrument (e.g.a LIGO) with a less precise instrument (e.g. vibration/seismic detectors). If you are aware of any specific literature on this process for LIGO, I am interested. The Caltech MIT link said that active control of the pendulum system is monito...
