Quantum Mechanics versus Reality. We experience part of our reality using our sense
of smell and our sense of touch. We are just
learning that Quantum Mechanics is at work here. Our reality is different than what we think it
is.

------------------ 2111 -- Quantum Mechanics
versus Reality
-
- We need
Quantum Mechanics to understand our "reality". Wait a minute. I can truthfully say I do not understand
Quantum Mechanics. But, I understand my reality
just fine. Why would I need
"quanta" to explain reality.
-
- My world is
continuous, smooth, flowing like time itself.
It does not come to me in little bundles of quanta.
-
- The first
example of little bundles came to science in 1900. Max Planck was the scientist to first propose
it. Planck was trying to explain why
heating a glowing metal rod turned red, then yellow, then white hot. Remember colors are frequencies, or
wavelengths of light. Red being the
wider wavelength and blue being the narrow wavelength.
-
- Each color is
a specific wavelength , or band of wavelengths.
As the rod got hotter it radiated more energy. When the early scientists used the math to
define the radiated energy they came up with an infinite amount of frequencies to explain it.. In other words the higher the temperature the
shorter the wavelength of energy. But, their
answers went to infinity.
-
- 1900's physicists
could not explain this phenomena until Max Planck came up with the idea that
energy could only be absorbed or emitted in discrete packets, or quanta. This was a radical proposal since energy was
thought to flow in smooth continuous waves, or streams.
-
- Planck
started it, but it took Albert Einstein, Werner Heisenberg, Niels Bohr and others to fully explain it and
to create the theory of Quantum Mechanics.
Quantum Mechanics appears to be an abstract world of science beyond our
life experiences. But, that is because we
still have more to learn.
-
- Believe it
or not you can actually smell the effects of Quantum Mechanics. Your nose is the only part of your nervous
system that is directly exposed to the outside world. Dangling direct from your brain are tentacles
of olfactory neurons. There are over 400
different neuron receptors on the inside surface of your nose.
-
- The early explanation
for our sense of smell was that the molecules of different odors interlocked
with specific neurons that match up.
Each different combination of receptors gave us a different sense of
smell. Each odor molecule having a
different shape locked on to a different receptor.
-
- So, we
smelling the shapes of different molecules.
-
- This model
explaining smell did not totally hold up.
There must be something more involved.
The proposal was made that the vibrating frequencies of different molecules
were somehow part of the explanation of smell.
-
- This idea was
first proven with experimental evidence when hydrogen and deuterium were
used. These two molecules have the same
shape but different vibration frequencies.
The nose could tell the difference.
So we smell vibrations as well as shapes. It does not stop there.
-
- Believe it or
not your nose is using Quantum Tunneling to distinguish different smells as
well. Molecular vibrations of a scent
molecule can allow electrons to tunnel from one smell receptor to another. This triggers nerve impulses that the brain
interprets as different smells.
-
- Quantum Mechanics
does not stop with the sense of smell. It is also used in the sense of
touch. The atoms on the surface of your
skin are mostly empty space. 99.999,999,999 % of each atom is empty
space. So, how can you feel a
surface. You don't. You sense the
resistance of negatively charged electrons from the atoms that are coming together
from one surface to another.
-
- It is the laws
of Quantum Mechanics that limit the specific
energy levels electrons can occupy. The
pressure of your touch forces electrons from one level to another. That requires energy from the muscles. Your brain interprets that energy as touching
something solid.
-
- Having solid
bodies is an illusion your brain creates.
One is reality and the other is "your reality". Our brains simplify things so we can understand
them. Our evolution does not favor accurate perceptions.
That is too complicated. It favors whatever
works for our survival. We are the result
of 3 million years of this simplification development. Whatever works!
-
- Reality is not
completely objective. We have not fully come
to grips with the quantum theory in the nature of our reality. We are working on it. Still more to learn!
