Video analysis of mathematical practice? Different attempts to ‘open up’ mathematics for sociological investigation

In this article I argue that in contrast to a large number of sociological studies of laboratory practices in the natural sciences, there have been relatively few studies that have investigated professional mathematical practice. I discuss three different methodological attempts to "open up" advanced mathematics for sociological investigation: (1) LIVINGSTON's "demonstrative sociology"; (2) MERZ and KNORR-CETINA's "e-mail ethnography"; and (3) my own "video ethnography."
