Division of Physics (MPS/PHY)

The U.S. National Science Foundation Division of Physics (PHY) supports fundamental research, infrastructure and training that empowers our understanding of nature from the smallest quantum-scale effects inside atoms to the universe-spanning forces that govern the movement and structure of galaxies.

Breakthroughs in physics have broad impacts on other fields of science and society as a whole, leading to new technologies like artificial intelligence, GPS and many others that improve our health and quality of life, strengthen national security and create new economic opportunities.
