Reiteration of the Experimental
Technique:
Use a fine-metering pipette to dis-
pense John's Baby Shampoo [or
the viscous fluid of your choice --
I've wanted to do it with Mobil 1
Motor Oil, but haven't done so yet]
into a petrie dish that contains an
evenly-distributed quantity of the
fluid you're using.
It's important to allow the bubbles
to rise out of both fluid resevoirs
before you undertake trials. Bubbles
introduce artifactual discontinuities
at the pipette tipand in the receiving
resevoir.
Then open the pipette's petcock
just enough so that a fine "thread"
of the viscous fluid flows continuously
from it into the receiving resieoir.
What you'll observe will be a build-
ing of a highly-dynamic little "mound"
of fluid at "the point" where the stream
impacts the resevoir's fluid.
This "mound" is literally a macroscopic
"atom".
It builds be-cause the rate at which
fluid enters it exceeds the rate at which
fluid can exit it -- because of the fluid's
viscosity.
And, as the mound's 3-D Topology
varies, you'll see little "squirts" of fluid
being ejected from the mound.
What's happening is that the fluid
collecting in the mound, and, within
the mound, it flows in a way that
minimizes averall energy-content.
This energy-minimization results in
fluid dynamics that vary the mound's
3-D Topology, and when such var-
iation flows toward the point at which
the fine stream of fluid flowing out of
the pipette meets the surface of the
mound, instances of non-minimal-
energy-flow occur, and, be-cause
of this non-minimalness, to the de-
gree of it, the fine-thread flow is
ejected from the mound.
These fluid-ejection dynamics shift
the fluid dynamics within the mound,
which terminates the non-minimal
energy condition, so the "squirting"
ceases.
This is an =exact= macroscopic
instance of what has been referred
to as "quantum shifts" with respect
to "atoms".
And such macroscopic fluid-dynamic
"atoms" behave in =exact= accord
with the Black Body Radiation.
This can be observed by performing
successive trials of the above ex-
periment while varying the Temper-
ature of the fluid over a range of
TempK.
At the low-TempK end of this
range, the "squirts" will occur at
relatively-high flow rates. [The
pipette's petcock will have to be
opened relatively much in order
to observe any "squirting".]
And as the fluid's TempK is in-
creased, the "squirting" will occur
at ever-smaller flow rates, in a way
that =exactly= matches the shift-
ing of the black body power spec-
trum toward its high-frequency end,
including the extreme-high-frequency
dropping-off of power.
What's very-nice about this fluid-
dynamics instance of the black body
radiation is that everything in it can
be easily calculated from continuous
flow-rates and 3-D Topology.
The fluid-mechanical "squirts" are
=exactly= analogous to what have
been referred to as "quantum" events,
but, in the fluid-mechanical case, it
is readily apparent that the underpin-
ning fluid dynamics are =continuous=,
and that the only thing that alters is
the directedness of fluid flow with
respect to minimal energy.
I have Verified that the same dynam-
ics acn account for all energy flows,
at all scales.
That is, I have Verified that there
is no need to propose that energy
is divided-up into "discrete packets".
I'll be happy to provide such com-
plete Verification to anyone who
wants to receive it in-person. [There's
a lot that needs to be covered, and
the dynamics inherent need to be
drawn and "animated" at a chaulk
board.]
