Schrödinger equation

If a thing could be a wave or a particle
then a classical trajectory cannot describe it.
Erwin Schrödinger derived an equation
for how a wave function changes over time.

The operation of time is unitary

Time changes each thing independently.
See how quickly the system
processes each quantum of energy,
its potential, its mass, and the momentums
of all its possible paths.
Multiple things in a system affect each other.
This could be a contraction,
or time always operates on the system,
or we have stopped thinking of mere time.
Time operates on the system because multiple particles
acting together have only one wave function.

Multiples

Multiple interpretations,
multiple solutions,
and multiple implications
of which multiple universes
and multiple multiplications
are possible
and possibly
probable.

I have illustrated the time-independent Schrödinger equation because it is simpler. The time-dependent Schrödinger equation is more explicit about space and time:

$i ħ \frac{δ}{δ t} Ψ (r, t) = Ĥ Ψ (r, t)$
