 
A Quantum World of Propensity Forms
Revisit: Hamiltonian Quantum Mechanics
 Energy operator generates the wave function,
 according to Schrödinger’s timedependent equation
 Propensity wave generates the actual measurement
 according to Born’s Probability Rule for y^{2}
 Actual measurements = selections of alternate histories
 ‘Energy’, ‘propensity waves’ are two kinds of propensity
Measurements are ‘Actual Selections’
 Actual measurements are selections of alternate histories
 Unphysical alternatives actually removed by some (undiscovered) dynamical
process.
 This sets to zero any residual coherence between nearlydecoherent histories,
if a branch disappears.
 Different alternatives u_{i}often summarised by an operator
A of which they are distinct eigenfunctions: Au_{i}=a_{i
}u_{i},
and labeled by some eigenvalues a_{i} .
‘Nonlocal Hidden Variables’ in ordinary QM:
 ‘Energy’, ‘propensity’ and ‘actual events’ are all present, though hidden,
in a ‘generative’ sequence.
 Energy and propensity exist simultaneously, continuously and nonlocally.
 Actual events are intermittent.
 Does this describe QM as we know it?
What does the wavefunction describe?
 The wavefunction describes dynamic substances, which are configurationfields
of propensity for alternate histories.
 The wavefunction of an ‘individual particle’ Y(x,t)
describes the ‘isolated’ propensity for xdependent decoherent alternatives
if these were initiated at time t.
Wholeness and Nonlocality
 The propensity fields:
 extend over finite space regions and time intervals, so are nonlocal,
 act to select just one actual alternative,
 subsequent propensity fields develop from the actual alternative
selected,
 ‘whole’ substances, but:
 usually contain many ‘virtual substances’ (see later) in whole ‘unitary
compound’
 So express using configuration space, not in 3D.
We need further analysis of ‘quantum composition’.
Summary
 I hope that this is an accurate classification of the several ‘stages’
in nature, as seen in QM.
 Should help to understand quantum physics and what really goes on.
 We can find ‘what the wave function describes’, if we think carefully
and with imagination.
