- Quantum Physics of
Determinism. Our natural world is
deterministic yet the building blocks that make it up are indeterministic,
totally acting at random. The logic of
physics says that indeterministic microphysics can lead to deterministic
macrophysics. Quantum randomness
indeterminism averages out to reality.

-------------------------------- 1793
- Quantum Physics of Determinism.
-
- Some things
just happen at random. With no rhyme nor
reason. Randomness seems to be a built
in feature of our natural world at its foundation.
-
- Radioactive
decay of atoms is totally random.
-
- Photons
striking a mirror reflect or pass through randomly.
-
- The theory
being that quantum mechanics is “ indeterministic”, it all depends on the
statistics of randomness.
-
- Einstein came
up with the theory in 1905 that light could be both a particle and a wave. The wave function that determines this is in
a perfectly deterministic equation, called the Schrodinger Equation. His equation is the “determinism” of a wave
function.
-
- Heisenberg
viewed the wave function as a probabilistic “haze” of potential
existences. He concluded that only when
you observe a particle does it materialize somewhere. Before observation the wave function was
spread over a huge region of space. At
observation it collapses into a narrow spike at a single position and becomes a
“ particle”. However, we have no laws in
physics that govern this collapse. It
just happens at random?
-
- For Einstein
wave collapse into a particle required instantaneous action at a distance. He reasoned that no communications could
travel faster than the speed of light.
Light speed was a Universal Constant at 186,000 miles per second.
-
- He had
trouble with “ measurement” being the “ creation” of reality out of the act of
observing it.
-
- Or, was the
wave function collapse not a physical process at all but more simply the
acquisition of knowledge inside our brains?
-
- What physics
was trying to demonstrate was that a probabilistic event through the underlying
reality was deterministic. ( mind
blowing!).
-
- The logic of
physics says that indeterministic microphysics can lead to deterministic
macrophysics. Quantum randomness
indeterminism averages out to reality.
-
- A baseball
can have atoms behaving randomly yet its flight can be totally
deterministic. Gas molecules have random
motion that together determine an exact temperature. A “temperature” being the average of a large
number of individual vibrating molecules.
-
- It appears
that the real world is a layer cake of indeterminism and determinism.
-
- The Earth’s
climate is dictated by laws of motion, daily, seasonally probabilistic events
however, long term trends are still predictable. Biology follows the same logic.
-
- Human
self-determination follows this layer cake logic as well. To truly have “free will” we need
indeterminism.
-
-
Macrodeterminism is your decision.
Microdeterminism is not.
-
- One gram of
Uranium 238 contains 2.5*10^21 atoms.
Each atom is identical and indistinguishable. Yet, 12,600 times per second one of these
atoms will decay throwing off an alpha particle. No theory in physics can pre-determine which
atom will decay when. It is a totally
random process yet it is predictable in the macro sense. Probability calculations can determine accurately how long it takes
for half of the atoms to decay (the half-life)
-
- Casualty
means that events can be completely determined by prior states. Is the entire Universe a single determinant
system? Is there an unbroken chain of
prior occurrences stretching back to the origin of the Universe? Is the future determined completely by
preceding events?
-
- Mathematical
models involving differential equations ( equations measuring the rate of
change over time) are not deterministic
because they involve randomness. Their
results have sensitive dependence on initial conditions. Theory implies that even as small as a
butterfly flapping its wings can cause a chain reaction that could lead to a
hurricane years later.
-
- Chaos Theory
tells us that it is impossible to predict real life events. The Schrodinger Equation uniquely predicts
the development of the wave function with time.
If the wave function is deterministic then Quantum Mechanics is
deterministic and that could imply that there is one single wave function for
the entire Universe starting at the origin.
-
- Our
individual atoms are random in motion, yet the enormous mass of atoms that make
up our bodies allow us to live and breath.
Human decision themselves reduce to the mechanics of atoms in our
brains. I have to stop thinking about
this. It makes me dizzy.
