The term nuclear-resonance is used by Pound-Snider
to describe a Mossbauer shift with altitude.

Are you sure that is how they used the term??

It is more likely that nuclear-resonance is used to describe the
Mossbauer effect itself, since the Mossbauer effect IS a nuclear
resonance effect.

" The classical phenomenon of the redshift of light in a
static gravitational potential, usually called the gravitational
redshift, is described in the literature essentially in two ways:
On the one hand, the phenomenon is explained through the
behavior of clocks which run faster the higher they are
located in the potential, whereas the energy and frequency
of the propagating photon do not change with height. The light
thus appears to be redshifted relative to the frequency of the
clock. On the other hand, the phenomenon is alternatively
discussed (even in some authoritative texts) in terms of an
energy loss of a photon as it overcomes the gravitational
attraction of the massive body. This second approach
operates with notions such as the "gravitational mass" or
the "potential energy" of a photon and we assert that it is
misleading. We do not claim to present any original ideas
or to give a comprehensive review of the subject, our goal
being essentially a pedagogical one.

I see NOTHING there suggesting that "The term nuclear-resonance is
used by Pound-Snider to describe a Mossbauer shift with altitude."

How many "F"s are there in Nuke-U-Lar?

You said:

to describe a Mossbauer shift with altitude.

Are you sure that is how they used the term??

It is more likely that nuclear-resonance is used to describe the
Mossbauer effect itself, since the Mossbauer effect IS a nuclear
resonance effect.

Show me where they say that 'nuclear-resonance' is the term that we use
when we are speaking of 'a Mossbauer shift with altitude.'

Okun et al ALSO seem to discount "gravitational mass" or "potential
energy" as an explanation for the shift, saying "we assert that it is
misleading."

I am surprised that you cited them because I thought that was your
horse. I thought you were against the 'clock speed' explanation for
the red shift that they seem to favor.

The "falling photon" is what is absurd. Slower motion in the
surface clock is completly consistant with inertial behavior.

Actually, the math seems to allow either model to work for that particular
experiment.

But I seem to recall you saying that clocks do not care what altitude they
are at and something about the faster drag racer not being left with fuel
in his tank, when you were saying that there are no clocks.

Maybe it is someone else that I am thinking about or I misunderstood your
point, like perhaps I misunderstood your point when you said the term ....
was used to refer to .... English is such a difficult language with so
many ambiguities



Aparently the absurdity wasn't generally recognized
untill a few GPS SVs demonstrated consistancy in the
launch presets. As Okun explains, the acceptance of
the absurdity was wide-spread in academia:
"even in some authoritative texts"
