  The radical changes in the concepts and approach in Physics at the turn of
the Nineteenth century were so deep, that is acknowledged as a revolution.
However, in 1970 Thomas Kuhn's careful reconstruction of the researches on the
black body problem, the concept itself of the revolution seemed to vanish in
his diluted discussion of every details. In the present paper, after an
examination of the limitations of Kuhn's response to his critics, I put forward
the idea, although it is not new, that these changes in Physics cannot be
reduced to a point-like event, but happened instead through multiple successive
(and even contradictory) changes in the course of decades. Such as the old
quantum hypothesis, wave mechanics, orthodox quantum mechanics. In fact, the
innovative perspectives started in the 1980s have been considered as a third
quantum revolution. My basic argument is that these changes, in order to be
really understood, must be interpreted not as mere specific changes in Physics,
but framed in the context of the deep social, cultural, and economic changes
during those turbulent years. The main steps are outlined.
