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.

GPMFC Workshops
The next workshop, "New Ideas in Dark Matter Searches", will be held as a satellite meeting with the APS April 2019 Meeting in Denver.

Over 300 were in attendance at the satellite workshop, "Precision-measurement Searches for New Physics," at the 2018 DAMOP Meeting. Thanks for Marianna Safronova and Dima Budker for organizing this exciting event!
