- History of Physics
Room VC 309
My research areas are the history of physics and the history of technology from the late nineteenth century to the present. I focus on how science and engineering have shaped each other at the levels of mathematical structures, physical theories, experimentation, instrumentation, and the development of new technologies. I am particularly interested in issues related to the production, justification, circulation, application, and transformation of technical knowledge in the mutual shaping between science and engineering. I also pay close attention to the different meanings and functions of technical knowledge to distinct professional or intellectual communities.
Along this direction, I have been undertaking six research projects:
- - Conceiving Noise: From Fin de Siècle to the Information Age
- - Studies of Wave Propagation and the Emergence of Active Sensing
- - Transformation of Electromagnetic Waves from a Novel Effect to a Research Object, 1887-1901
- - Chao Yuen Ren and the Modern Soundscape of Republican China, 1912-1937
- - The Very Recent History of Quantum Information
