The APS is closed on Monday, January 20 in observance of Martin Luther King, Jr. Day. 

Franklin’s spirit of inquiry remains alive and well. The APS is guided by the belief that the pursuit of useful knowledge remains essential to our society and is inherently in the public interest.

Today, the Society honors distinguished scientists, humanists, social scientists, and leaders in civic and cultural affairs through elected Membership, and engages them through its annual Meetings. APS grants, fellowships, lectures, publications, and prizes also encourage groundbreaking research and discovery. The APS Library and Museum are dedicated to supporting scholarly research and sharing their rich collections with the public.

As a supporter of useful research and a forum for the free exchange of ideas, the APS will continue to engage the most important issues facing our society.
