Text-only version of the old website: Ellery Frahm, Electron Microprobe Lab Geology and Geophysics Anthropology Department University of Minnesota Twin Cities, The future is not only on the edges of a discipline, but where two edges touch, and that is where the excitement is. And two edges of our pursuit of truth are about to touch Robert Ballard Within some archaeological artifacts there is a record to which an archaeologist is blind but which a physicist can hope to read [but] a physicist is not a machine that, when fed with material, regurgitates an archaeological answer acceptable without qualification. Martin Aitken every archaeological problem starts as a problem in geoarchaeology.
