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 (IOPNAP) founded in Beiping in 1929. The director of the IOPNAP, physicist Yan Jici, was appointed director of the new institution after the merger was completed in 1950. The new entity was named the Institute of Applied Physics before being renamed to Institute of Physics in 1958. 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, a partnership agreement between the IOPCAS in mainland China and IOPAS in Taiwan was signed by their directors during the celebration of their 80th anniversary of foundation amid a warming trend in cross-strait relations of the time.
