Brownian Motion and Molecular Reality

George E. Smith, Professor of Philosophy, Tufts University, Raghav Seth, Anesthesiology Resident, Beth Israel Deaconess Medical Center George E. Smith has maintained two professional careers, one as a mechanical engineer and the other as a professor of philosophy. In the first of these, which began in the late 1950s, he first specialized in the development of computer-based methods for designing jet engines at General Electric and Pratt & Whitney Aircraft. From the late 1960s until he retired from this career in 2013 he was a failure analyst specializing in vibration related fatigue failures in jetengines and other turbomachinery. In his academic career he has been a member of the Philosophy Department of Tufts University since 1977, receiving his PhD in philosophy from MIT in 1979. He specializes in the critical assessment of evidence in the physical sciences - especially during historical transitions in which areas ofresearch go from struggling to extract high quality evidenceout of data to becoming exceptionally effective in doing so. He served as Acting Director of the Dibner Institute for the History of Science and Technology at MIT from 2001 until 2006 and has twice been a Distinguished Visiting Professor in the Philosophy Department of Stanford University. Raghav Seth graduated from Tufts University in 2012 with a B.A. in Philosophy. After college, he worked as a research assistant at the McGovern Institute for Brain Research at MIT and then as an EMT in Essex County before transitioning to medical school at the Tufts University School of Medicine from which he graduated in 2018. He is currently an anesthesiology resident at Beth Israel Deaconess Medical Center.
