materials that ghost through electricity, giving zero resistance and zero apology.
means substances that carry electric current with absolutely no energy loss once cooled below a critical temperature.
from discovered in 1911 by heike kamerlingh onnes, who supercooled mercury and watched its resistance simply vanish, a result so odd he checked his wiring twice.

nobel prizeonnes won one in 1913 for this.
