Query: The origin of rotation, dense matter physics and all that: a tribute to
  Pavle Savic   This is a review of the main physical ideas and examples of applicability in
astrophysics and pure physics of a semiclassical theory of dense matter
proposed by Pavle Savic and Radivoje Kasanin in the early sixties. A
hypothesis, advanced by Savic with the aim of solving the problem of the origin
of rotation of celestical bodies,will also be discussed. The paper is dedicated
to the memory of Pavle Savic, who died recently.
