In 1913, the “WuLi Men” (physics division) was established at Peking University, and this was later renamed the Department of Physics in 1919. With the reorganization of the Chinese system of higher education in 1952, the new Physics Department of Peking University was created from the merger of the physics departments of Peking University, Tsinghua University and Yenching University. This became the premier center for physics in China. The School of Physics was established in 2001, and includes not only the traditional fields of study in physics, but also related physical sciences. Today, the School of Physics includes Physics, Astronomy, Atmospheric & Oceanic Sciences, and Nuclear Science & Technology and consists of eleven divisions and seven related research institutes,including the State Key Laboratory for Artificial Microstructure and Mesoscopic Physics and the State Key Laboratory of Nuclear Physics and Technology.
