In quantum physics, the Heisenberg uncertainty principle states that one can not assign,
with full precision, values for certain pairs of
observable variables, including the position and momentum, of a single particle at the same time even in theory.
And, through a transformation of state
variables, you can reduce the expansion to a smaller set of ODEs,
with a nonlinear relationship for the
observable,
with well separated resonant frequencies in the model.
Given an ensemble of models from which an
observable variable takes the mean value m 1 = 0 (without loss of generality) and standard deviation s 1, and an observation of this
variable which takes the value m 2
with associated uncertainty s 2, the observation is initially at a normalised distance m 2 / s 1 from the ensemble mean.
On the other hand, as we have seen, the testing of a theory involves the identification of its
variables with some «true»
observable variables.
