|| I appreciate your sentiments about my contributions here.
|| Your own work, as you well know, deviates rather substantially from
| classical "doctrine." Although my politics is rather distinctly
| different, in technical terms about matters of science I am a very
| traditional conservative, hewing closely to the "party line". You do
| say you "rewrite Physics, but no one else understands that rewritten
| stuff yet." I agree you rewrote something and the no one else
| including me understands it. Unfortunately, some of your arguments,
| such as the ones here regarding energy, black-body radiation, and
| vibrational frequencies are rather a bit off the mark (in my
| old-fashioned traditional view). And these tend to be very
| off-putting when making decisions on how much time to spend going over
| you material.
|| A change of 1/2 degree C is less than a 0.2% change in absolute
| temperature. There is no significant change in black body radiation
| that occurs as a result -- Stefan's law says that the total energy
| emitted would increase by less than 1% (fourth power relationship) and
| Wien's law says the peak wavelength would change less than 0.2%
| (inverse proportionality). These won't make any significant changes
| in anything. The wavelengths are already deep in the infrared and
| would just very slightly modify some molecular vibrations. Again,
| these types of variations are trivial compared with the normal
| temperature fluctuations experienced by neurons in everyday life.
|| There do exist situations where the system has singular points or
| bifurcations and very small changes in a system parameter (like T)
| makes sudden large changes in behavior. There is no known physical
| chemistry like that for changes in cellular biochemicals showing a
| state or functional transition in the 30 - 40 C range. And for good
| reason -- as I pointed out, the cells are constantly subject to these
| fluctuations. Furthermore, all cellular processes in neurons are
| shared widely across the animal kingdom, including animals whose
| brains function well across extreme temperature changes -- 0 C to 30
| or 40 C.
I stand on what I've posted.
You're overlooking some sig-
nificant stuff, Dr. Norman.
1. "Fever" dynamics present a
=generalized= TempK variation
that 'ignores' any TempK "fluctua-
tions" that, somehow, make it past
the nervous system's exquisite "rad-
2. Every ion [and 'atom] experi-
ences the small TempK variation,
and it's the cumulative effect that
determines the functional altera-
tions that I referred to in my pre-
vious post [and long-former "NL-P
Medicine" posts, and my long-former
discussions of Tapered Harmony].
Yes, I've worked-through stuff
that others do not, yet, have ac-
cess to, but that's not because
I've not offerred to share that
stuff with folks, and I'm going
to continue to expect that folks
who want such access will meet
with me in-person.
Be-cause it's just getting too-
"strange" that no one will do so.
I have to allow for the "clone-
server" alternative because I've
sufficient data to substantiate
