The most obvious example is that most of us to all intens and purposed live in a universe that is governed by the laws of Newtonian physics, although these laws are inadequate for most modern theoretical physicists-indeed, so are the laws of Einsteinian relativity for some of them: whereas some of us are just beginning to grasp those as an intellectual exercise of little application to daily life, the frontiersmen of sub-atomic physics live in a stochastic Heisenberg universe ordered by degrees of uncertainty and probability.
