Institute of Physics, Chinese Academy of Sciences

The Institute of Physics of the Chinese Academy of Sciences (IOPCAS Chinese: 中国科学院物理研究所) was the result of a merger, after the communist took control of the mainland China in 1949, between the Institute of Physics of Academia Sinica (IOPAS) founded in Shanghai in 1928 and the Institute of Physics of National Academy of Peiping [zh] (IOPNAP) founded in Beiping in 1929.

[1] In Taiwan, the IOPAS was re-established in Taipei in 1962 by another "founding father" of modern Chinese physics - Wu Ta-You.

Claiming the same root,[2][3] a partnership agreement between the IOPCAS in mainland China and IOPAS in Taiwan was signed by their directors[4] during the celebration of their 80th anniversary of foundation amid a warming trend in cross-strait relations of the time.

[9] The IOPCAS established partnership with institutions and universities of over 30 countries, such as Stanford University, University of California, Berkeley, the Royal Society of London, Centre National de la Recherche Scientifique, Max Planck Society, Japan Society for the Promotion of Science, among many others.

[10] The IOPCAS is the major sponsor of Chinese Physical Society (CPS), a nongovernmental organization which can find its roots in 1932, today officially affiliated to the China Association for Science and Technology.
