Danian Hu focuses on the fate of relativity in the physics community in China after 1917. Zuoyue Wang hopes that a less nationalist political atmosphere in China will stimulate more transnational studies of modern science, which will in turn reveal (...) the underlying commonalities in different national contexts. Sigrid Schmalzer compares the socialist and the capitalist contexts for science in China and reopens the sensitive question of the “mass line” during the Cultural Revolution. Grace Shen describes the tensions early Chinese scientists felt when choosing between foreign models for modern geology and their own professional identities in China.
