Mission & Focus Areas
APS’s mission is to advance physics by fostering a vibrant, inclusive, and global community dedicated to science and society. Its stated vision is a world inspired, enriched, and sustained by a thriving physics enterprise. Its website highlights scientific integrity, equity and inclusion, collaboration, education, and public engagement among its core values.
The 2024 grants included subawards and participant travel support. Recipients included universities and scientific societies. For example, the American Mathematical Society describes its mission as serving the mathematical community through publications, meetings, advocacy, and other programs that promote mathematical research and education. The American Astronomical Society describes its objective as advancing astronomy and related sciences. These are the recipient organizations’ missions, not APS’s.
Grantmaking
In filing year 2024, APS reported 37 grants totaling $1,749,882. Grant amounts ranged from $6,000 to $222,817, with a median of $24,517. The largest awards included $222,817 to Wested for subawards, $202,536 to the University of Maryland for program subawards, $195,167 to the American Mathematical Society for subawards, and $156,137 to Florida International University for subawards. Other listed recipients included the American Astronomical Society ($78,202), the University of Central Florida ($68,385), and the Rochester Institute of Technology ($51,677).
The filing says recipients are selected using criteria set by oversight committees. Grant awards are reviewed by senior staff and committees; recipients receiving lump-sum payments are expected to submit final reports detailing expenditures, while reimbursement recipients must provide expense reports with receipts. Formal prizes and awards are based on prior accomplishments and approved by the Council of Representatives.
APS’s Innovation Fund offers pilot or supplemental funding to members for projects addressing challenges in the physics community. The 2025 cycle focused on climate science education and careers, with a pre-proposal deadline of May 6, 2025; that deadline has passed.
