The American Institute of Physics is a federation of physics-related scholarly societies with the goal of advancing and promoting the physical sciences. AIP was first founded in 1931 in New York, but has since moved much of its operations to College Park for proximity to both other locally based member societies and the federal government in Washington DC.
To celebrate the 90th anniversary, AIP is hosting a free virtual event and Trivia Night on July 22. You can learn more and sign up for the event at https://www.aip.org/aip-90th-trivia-night . Space is limited, so sign up soon!
