is that there is still a good case against emission theories but that the evidence is different from and less than it has been thought to be." Other professional activities In the late 1940s and 1950s, Fox was part of the Carnegie Tech team that created the then state-of-the-art 450 MeV synchrocyclotron at the Nuclear Research Center in nearby Saxonburg. (The experiment with Filippas, noted earlier, was performed at this facility.) He served as head of Carnegie Tech's department of physics from 1955 to 1961. In 1962/63, Fox spent a sabbatical year in France at the Laboratoire Joliot-Curie de Physique Nucléaire d'Orsay, in part because of the new synchrocyclotron installed there. In 1967/68 and 1971/72, Fox spent a total of three years living and working in India at the newly formed Indian Institute of Technology, in Kanpur, first as a visiting faculty member, and then as administrative head of the Kanpur Indo-American Program. Fox was also a consultant to the Nuclear Medicine Department of St. Francis General Hospital, in Pittsburgh. Further reading In 2004, Alberto Martínez examined the rejection of Ritz's emission theory in favor of special relativity from a historical perspective. That work discusses Fox's findings at some length.
