“…Other ostensible examples of infinite or infinitesimal idealizations include fractional quantum statistics as portrayed by anyons in the fractional quantum Hall effect (Shech, 2015a, 2018a, 2018b), superselection rules (Butterfield, ; Earman, ), fractals (Butterfield, ), catastrophe optics (Batterman, ), semiclassical mechanics (Batterman, ; Bokulich, ; Landsman, ), point‐particle idealizations in general relativity (Tamir, ; Wayne, ), thermodynamically reversible processes (Norton, ; Valente, ), and systems portraying indeterminism such as a dome with infinite curvature at its peak, an infinite array of masses and springs, and an infinite domino cascade (see Norton, , for these examples), as well as various supertasks (Manchak & Roberts, ).…”
