Topical Group on Precision Measurement & Fundamental Constants

The Topical Group on Precision Measurement & Fundamental Constants is a subunit of the American Physical Society. Its objective is to serve as a focus for research related to investigating and testing the fundamental laws of physics and their underlying connections, determining fundamental constants, and developing and improving basic measurement standards, with special emphasis on the high precision experiments that are characteristic of such research.
