Andrew Ludlow, a physicist at the National Institute of Standards and Technology, built the most precise atomic clock ever. Better atomic clocks will facilitate and faster telecommunication networks. And some physicists are excited about another application: testing Einstein's Theory of Relativity.
Einstein predicted that certain physical properties, like the strength of the interaction between photons and electrons, or the ratio of the mass of electrons and protons, should never change. But competing theories say that those 'fundamental constants' might actually fluctuate and such changes would slightly influence the ticking speed of atomic clocks.
