, of the 2003 Nobel Prize in Physics for making pioneering contributions to the theory of superfluids (see superfluiditysuperfluidity,
tendency of liquid helium below a temperature of 2.19°K; to flow freely, even upward, with little apparent friction. Helium becomes a liquid when it is cooled to 4.2°K;.

). In the 1970s Leggett elucidated how atoms interact and are ordered in the superfluid state, when a liquid's viscosity becomes zero and the liquid exhibits unusual properties.
