I was reading a recent article on the very cool topic of topological insulators when it reminded me of an interesting period of time.
Superconductivity, the phenomenon of complete absence of electrical resistance, was first observed by Heike Kamerlingh Onnes in 1911. The observation was readily repeatable, and Onnes won the 1913 Nobel Prize in Physics for its discovery. However, for nearly 50 years there was no theoretical explanation that really satisfied the physics community. But during the 1950s the BCS theory of Cooper pairs of electrons acting as phonons was developed that described a mechanism for superconductivity.
Never, to my knowledge, did the physics community assume intelligent design was the answer for why superconductivity existed. There was not naturalistic explanation for 50 years, yet they never lobbied for a supernatural explanation as the 'default' or inference to the 'best' explanation. I wonder why that is?
