This explanation would require helium II to have an abnormally low viscosity; at present, the only viscosity measurements on liquid helium have been made in Toronto 1, and showed that there is a ...

Consequently any known formula cannot, from our data, give a value of the 'viscosity' which would have much meaning. It may be possible that the liquid helium II slips over the surface of the tube.

Liquid helium, when cooled down nearly to absolute ... flows freely through impossibly small channels, completely lacking viscosity. It becomes a new state of matter -- a "superfluid." ...

The first liquid in which superfluidity was recognized was helium-4 back in 1938. It loses its viscosity below 2.12 K. At the time Fritz London suggested that the phenomenon was associated with ...

(Among other bizarre properties, liquid helium can flow upwards because it has zero viscosity and its capillary action is stronger than gravity.) The Anglo-Austrian team manufacture droplets of ...

In a breakthrough that challenges conventional physics, scientists have confirmed the existence of “second sound” — a phenomenon where heat travels as a wave rather than dispersing slowly, as it does ...

In the case of helium ... to viscosity. This transition has the potential to make things worse. In the past, researchers targeted temperatures right at the transition, where the liquid helium ...

liquid helium is already strangely cold for a liquid, but when it is approximately 2 degrees colder it becomes even stranger. At this temperature, quantum effects make its viscosity vanish and ...

The helium must be not just liquid, but superfluid liquid helium, which, similar to a superconductor with no resistance, has no viscosity or friction. Looks Like We Have a New State of Matter All ...
