This course examines the frequent and significant encounters between what chemist/novelist C.P. Snow famously dubbed the "two cultures"-the sciences and the humanities-with an emphasis on forms and practices of visual culture that blur the boundaries between science, technology, and art. What role, we will ask, have visual culture and visuality played in the construction of scientific knowledge? Taking a broad historical and geographical approach, we will explore topics including representations of science and technology in the arts and popular culture; the use of photography, illustration, and visualization in the sciences; histories of visuality and visual devices; and the everyday visual practices of scientific inquiry.
