superconductivity

Popular Terms
Total or almost total lack of resistance to the flow of electric current. Some metals and their compounds lose their resistance uniformly as their temperature drops and, within a few degrees of the absolute temperature (-273.15°C or -459.67°F), it suddenly disappears and the current flows indefinitely. In recent times researchers have achieved similar results at temperatures as high as -179°C (-405°F). The phenomenon of superconductivity was discovered in 1911 by the Dutch physicist Heike Kamerlingh Onnes.
