 For example, sometimes replication was sufficient to embrace a research claim, even if it conflicted with the background of accepted theory and left theoretical questions unresolved. A case of this is high-temperature superconductivity, the effect whereby an electric current can pass with zero resistance through a conductor at relatively high temperatures. In 1986, physicists Georg Bednorz and Alex Müller reported finding a material which acted as a superconductor at 35 kelvin (−238 degrees Celsius). Scientists around the world successfully replicated the effect, and Bednorz and Muller were then awarded with a Nobel Prize in Physics a year after their announcement. This case is remarkable since not only did their effect contradict the accepted physical theory at the time, but there is still no extant theory that adequately explains the effects which they reported (Di Bucchianico, 2014).
