QUANTUM THEORY:
classical physics as developed by NEWTON held that it was possible to
know both the speed and position of any particle. With HEISENBERG'S uncertainty principle,
modern physics recognized that we can know either the speed or the position of a particle
but not both. The implication of these findings, which were given expression in the work
of Nils BOHR, Max PLANCK and Albert EINSTEIN, is that the older mechanistic view of the
physical UNIVERSE which was essentially deterministic no longer holds true. As a result,
arguments such as those of David HUME against the possibility of MIRACLES are no longer as
sound as they once seemed.
