| contents | In the last 175 years, the physical understanding of
nature has seen a revolutionary change. Until about 1850, Newton's
theory and the mechanical world view derived from it provided the
dominant view of the physical world, later supplemented by Maxwell's
theory of the electromagnetic field. That approach was entirely
deterministic and free of probabilistic concepts. In contrast to
that conceptual edifice, today many fields of physics are governed
by probabilistic concepts. Statistical mechanics in its classical or
quantum version and random-matrix theory are obvious
examples. Quantum mechanics is an intrinsically statistical
theory. Classical chaos and its quantum manifestations also require
a stochastic approach. The paper describes how a combination of
discoveries and conceptual problems undermined the mechanical world
view, led to novel concepts, and shaped the modern understanding of
physics. |
