States of aggregation

APR 01, 1969
As gases condense into liquids and then solids, an order pattern develops in position space. Both superconductivity and superfluidity can be viewed as condensations in momentum space. Possibly life itself is an order pattern, perhaps in both spaces at once.
Kurt Mendelssohn

SUPERFLUIDITY and superconductivity (figures 1 and 2) can be discussed in terms of a subject much older than either: states of aggregation.
