Cool Physics #11: Looking for Extra Dimensions

A review of some physics experiments that probed the existence of extra spacial dimensions at small scales. They also were instrumental in constraining some of the properties of dark energy.

The primary research group is the Eot-Wash group at the University of Washington: https://www.npl.washington.edu/eotwash/

The three papers, in particular, that we explore (one is a recent result from a Chinese group) are below. They all appeared in Physical Review Letters.
