Resistive transition measured in Sn-2%In whisker crystal superconductor. AL: Aslamazov and Larkin, MMP: Marcelja, Masker and Parks, MH: McCumber and Halperin. At very low temperatures MH becomes the correct theory.

Resistive transition in disordered thin Al film superconductor, with magnetic field values shown in the figure. The form of the transition was first predicted considering Cooper pair fluctuations, and then measured by W. E. Masker in the laboratory of my Ph. D. supervisor Ron Parks, at the University of Rochester, Rochester, New York. Never again have I made a prediction that holds over 6 orders of magnitude! Both figures are from W.E. Masker, S. Marcelja and R.D. Parks, Electrical conductivity of a superconductor, Physical Review 188 (1969) 745.
