High precision technology offers a powerful new approach for particle physics. Discovering the answers to open questions such as the hierarchy problem and the nature of dark matter may in fact require a new, high precision approach instead of conventional techniques. Examples of such new physics include the axion, a solution to the strong CP problem and strongly-motivated dark matter candidate. Technologies such as atom interferometry, nuclear magnetic resonance, and high precision magnetometry allow novel, highly sensitive experiments for direct detection of dark matter and new fundamental interactions. These approaches are similar in many respects to gravitational wave detectors. I will discuss several new detectors for dark matter and/or gravitational waves. Such precision experiments will open new avenues for probing the origin and composition of the universe.
