DESCRIPTION:In 1938 Petr Kapitza\, investigating properties of the low temp
erature phase of liquid 4He\, discovered that viscosity of the
liquid is more than 104 times smaller\, than that of all known
liquids. Kapitza concluded\, that the liquid is in a new state of matter\,
a “superfluid”\, which to some extend analogous to superconductors. L
andau (1941) explained the phenomenon and predicted several its unusual pr
operties. It occurs\, that in a superfluid in any point of space at finite
temperatures simultaneously exists two flow with different velocities. On
e is “normal” and has finite viscosity and the second one is “superf
luid”\, which viscosity is exactly zero. This results in presence of two
type of sound\, which were discovered experimentally in 1946.\nVortragend
