I think I read it. But I forgot it completely!
There are many way to get the Schroedinger equation
(Einstein himself derived the equation as soon as 
he got some information from Lorentz!). Essentially 
it is a diffusion equation, with no predetermined time 
arrow. It is possible to write a 'double' diffusion
equation with two opposite time arrows. But the physical 
interpretation of the S. equation is still difficult. 
(Even the interpretation of the fundamental equation 
of the 'realistic' Bohmian quantum mechanics is difficult, 
since many do not like the 'quantum potential', and since the 
trajectories of the particles are, very often, completely 'surreal').
And there are many derivations of Robertson-Heisenberg
uncertainty relations. D.Deutsch and G.C.Ghirardi are writing 
down a completely different uncertainty relation based 
on 'entropy' (or information gain), that is the best 
possible choice, to avoid the well known inconsistencies.
