Mingyi Yu is a sixth-year PhD student in the Film and Visual Studies program at Harvard University. His primary area of research is the media philosophy of information systems, with a specific focus on the transition era of early electronic digital computers between the 1950s and 1970s, from a device oriented to the performance of calculations, to an audiovisual medium operated via interface and a basic grammar of ‘body techniques’ (typing, clicking, swiping, etc.). Particular topics of interest include: the cathode-ray tube as a component of the computer; hardcopy output devices; humanistic tendencies in computing discourse of the 1950s. Beyond this historical moment, interests extend both: (1) toward the present day ubiquity of so-called ‘digital culture’; (2) toward the deep histories of computing techniques and the expanded field of computational styles of thought (the calculus of symbolic notations, index cards, filing systems, note-taking and reference strategies, etc.).
