TEM

Transmission Electron Microscope.

TEMs use electrons as “light source” and their much lower wavelength makes it possible to get a resolution a thousand times better than with a light microscope(from the Nobel Prize website)

Hypothesized in 1929 by Knoll and Ruska at the Technische Hochschule, it was first built in 1932. A North American prototype of the transmission electron microscope (TEM) was constructed starting in 1937 at the University of Toronto. For a detailed account of the history and the politics involved in its construction and its initial and later applications see Rasmussen, N, in Studies In History and Philosophy of Science Part A, 1996

the role of technologies

Technology-mediated vision, we are reminded, excludes the contact with its reality (Robins, from Into the image 1999). This attitude is neither unlike the one proposed by modernist planners and architects, nor is it radically different from the objectives that lie behind today’s ubiquitous surveillance cameras. Modernist architecture

sought to erase what we may call the city of touch, and in its place to construct the glass city (19).

Its fundamental objective was “that of transparency,” aspiring to the idea of universal panopticism, through which it seems possible to “achieve order, and consequently master, the urban space (20).” Like the glass window separating the observer from the observed, thanks to the process of visualization, viruses are never experienced directly, but through a number of filters and layered operations.
