Helen Rhoda Arnold Quinn (born 19 May 1943) is an Australian-born particle physicist and educator who has made major contributions to both fields. Her contributions to theoretical physics include the Peccei–Quinn theory which implies a corresponding symmetry of nature^{[2] [3]}(related to matter-antimatter symmetry and the possible source of the dark matter that pervades the universe) and contributions to the search for a unified theory for the three types of particle interactions (strong, electromagnetic, and weak). As Chair of the Board on Science Education of the National Academy of Sciences, Quinn led the effort that produced A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas^[4][5]—the basis for the Next Generation Science Standards adopted by many states. Her honours include the Dirac Medal of the International Center for Theoretical Physics, the Oskar Klein Medal from the Royal Swedish Academy of Sciences, appointment as an Honorary Officer of the Order of Australia, the J. J. Sakurai Prize for Theoretical Particle Physics from the American Physical Society, the Karl Taylor Compton Medal for Leadership in Physics from the American Institute of Physics, the 2018 Benjamin Franklin Medal in Physics from the Franklin Institute, and the 2023 Harvey Prize from Technion -- Israel Institute of Technology.
