Two of the fundamental “laws” of physics are being outrageously violated in laboratories by a liquid, helium II. This is ordinary helium reduced to 2.2 degrees above absolute zero (-273.18° C or ...

This is a preview. Log in through your library . Abstract An experimental investigation of the propagation of second sound in uniformly rotating resonators filled with liquid helium II has been made.

IT has been suggested that, for the explanation of the abnormal properties of liquid helium II, a division of the molecules into molecules ‘at rest’ and ‘moving’ ones is an essential feature 1,2,3.

I AM glad to endorse certain points which Prof. Tisza has made in his letter, especially that the behaviour of helium II cannot be explained by assuming extreme values for macroscopic parameters, and ...

Liquid helium has fascinated scientists ever since it was first produced by the Dutch physicist Heike Kamerlingh Onnes in 1908. One of the biggest surprises was that liquid helium-4 forms a substance ...

This is a preview. Log in through your library . Abstract An experimental study has been made of the period and logarithmic decrement of a single disk and of a pile of equally spaced disks performing ...
