Physics (from Greek φυσική / physikê meaning science of nature) is the science concerned with the discovery and understanding of the fundamental laws which govern energy and spacetime. Physics deals with the elementary constituents of the universe and their interactions. Therefore, it can be thought of as a foundational science, upon which stands "the central science" of chemistry, and the earth sciences, biological sciences, and social sciences. Discoveries in basic physics have important ramifications for all of science.
Physics, like all the sciences, is a work in progress. Experimental and theoretical physics researchers continue to find new phenomena and to create and refine new models and theories.

| National Superconducting Cyclotron Laboratory |
The National Superconducting Cyclotron Laboratory (NSCL) is a United States laboratory that focusses on rare isotope research. Established in 1963, it is located on the campus of Michigan State University. Funded primarily by the National Science Foundation, the NSCL operates two superconducting cyclotrons. In December 2008, the Department of Energy announced that the NSCL would host the Faculty for Rare Isotope Beams. The NSCL employs 300 people, and awards ~10% of the United States' nuclear science doctorates.
Members of the Constellation Program test the space craft Orion's separation rockets.
