Every year, the American Physical Society recognizes a select number of sites in the United States where important events in the history of physics took place.
With your nomination, you are helping to raise public awareness about noteworthy events and illuminate the impact of scientific advancements on everyday life.
New sites are selected by the Historic Sites Committee. Awardees receive a plaque commemorating the site's significance to physics, and a listing in the Historic Sites online directory.
Congratulations to our newest historic sites, Chicago Pile “Site A” and Stagg Field!
