Yesterday Sharon Traweek from UCLA visited HUMlab. She had been invited to Umeå by the National Graduate School of Gender Studies. I learnt a lot from her just talking to her for an hour or so. When I read “Iconic Devices: Toward An Ethnography of Physics Images” (one of her papers) I realized that we share a strong interest in physical environments and their social and cultural meanings. Traweek has done research on Japanese “big science” among other things. We talked about structures changing, center-periphery, overlapping networks and more.
