Description

Reliable measurements of gravitational forces at scales smaller than a centimeter carry significant challenges. The non-gravitational forces that are generally negligible at the scale of everyday objects have a much more substantial effect in the sub-centimeter regime. Due to the nature of precision required in measuring micron-scale gravitational forces and the inherent weakness of gravity, it is important to record, model, and possibly suppress environmental effects in and around the experiment that may affect measurements. Recently, members of the Cal Poly Gravitational Physics Lab have focused on developing these environmental instruments and models to ensure high levels of precision.
