The physical world is governed by laws describing how matter and energy interact at scales ranging from the smallest particles to the entire universe. Physicists are using the Oak Ridge Leadership Computing Facility’s enormous computing power to reveal the nature of matter at its most elusive—from the behavior of the quarks, electrons, and other fundamental particles that make up atoms and everything we know, to the workings of the molecules made up of those atoms.
