The second idea proposed in 1932 by Bohr and Kronig was that superconductivity would result from the coherent quantum motion of a lattice of electrons. Given Bloch’s stature in the field, theorists like Niels Bohr where eager to discuss their own ideas with him. In fact Bohr, whose theory for superconductivity was already accepted for publication in the July 1932 issue of the journal “Die Naturwissenschaften”, withdrew his article in the proof stage, because of Bloch’s criticism (see Ref.[20]). Kronig was most likely also aware of Bloch’s opinion when he published his ideas[22]. Only months after the first publication he responded to the criticism made by Bohr and Bloch in a second manuscript[23]. It is tempting to speculate that his decision to publish and later defend his theory was influenced by an earlier experience: in 1925 Kronig proposed that the electron carries spin, i.e. possesses an internal angular momentum. Wolfgang Pauli’s response to this idea was that it was interesting but incorrect, which discouraged Kronig from publishing it. The proposal for the electron spin was made shortly thereafter by Samuel Goudsmit and George Uhlenbeck[29]. Kronig might have concluded that it is not always wise to follow the advice of an established and respected expert.
“History of what didn’t work” seems like an important genre, for example if you want help avoiding hindsight/survivorship biases. Are there other good examples? It seems a lot of histories of science impose a false sense of direction or inevitability and don’t cover many dead ends if any; all I can think of are some biographies that cover a lone genius’s missteps on his way to the true theory.
Pseudoscience is sometimes useful for finding examples—there’s a whole subclass of pseudosciences (particularly in alternative medicine and pseudophysics) that are based on advocating an old formerly-mainstream theory that turned out to be wrong. It would almost be a reliable way to generate new alternative medicines.
Failed theories of superconductivity. My favorite part:
