Physicists and Philosophers Debate the Boundaries of Science
&quot;Massimo Pigliucci, a philosopher at the Graduate Center of the City University of New York, pointed out that falsifiability is woefully inadequate as a separator of science and nonscience, as Popper himself recognized. Astrology, for instance, is falsifiable — indeed, it has been falsified ad nauseam — and yet it isn’t science.&quot;<p>You could say the same for phlogiston or N-rays. Falsifiable hypotheses that actually get falsified are dropped from science, but the process of falsifying them is a scientific activity.
