Well wait for the mark 2 version of the Occam paper, where I shall be
far more explicit in the steps. Sorry it is taking so long, but I have
a real job to do as well.

One of the Kolmogorov probability axioms is that the certain event has
probability 1. Conservation of probability is simply asserting that
the probability of the certain event does not change over time. A
fairly obvious corrollory one would have thought.

Saying that the i is there makes it easier to write misses the
point. The Schroedinger operator is i times a Hermitian operator. This
is not the most general form of linear operator, so this structure
ought to have some form of explanation. The one I gave is not actually
due to me, but I can't think where I first came across it - possibly
Emile Durand.
