There seem to be more to Avogadro's constant, N_A, then is
normally portrayed about it in literature. These, N_A's unspoken
traits, may be one of the causes of the problems that make it
difficult to nail down a very accurate numerical result for N_A....
........[snip]..... a few old (1930?) relations/equations that
may illuminate this accuracy-dependcency problem, such as:
One mole of Planck time equals the atomic time unit:
tau / t_pl = a^(-1) * (N_A*pi*sqrt3)
or one mole of Planck length equals the H-Bohr radius or
the classical electron radius:
r_H / l_pl = a^(0) * (N_A*pi*sqrt3)
r_e / l_pl = a ^(2) * (N_A*pi*sqrt3)
or that one mole of electron masses equals the Planck mass
m_pl / m_e = a^(1) * (N_A*pi*sqrt3)
So, since all Planck units are combos of hbar, c & G, one can see
that there are, for instance, the following relationsships between
N_A and Newton's G, when re-expressing the above equations by
straight forward means and substituting the Planck units, *_pl,
with hbar, c, & G, as:
G * N_A^2 = [1/3] * [ hbar * c] / [pi* a* m_e]^2 = const
or equivalently:
G * N_A^2 = [2/(3pi)] * [c^3] * [r_H^2 / h] = const
or there are
others like, G * N_A^2 = f(tau, etc) = f(Lyman freq, etc) = const
........[snip]........
It may be akin to something like k*N_A = R(gas) or e*N_A = F
where N_A couples the atomic domain of heat or electricity to/with
the everyday cgs/MKS mole sized experience in the respective fields.
Similarly, this G* N_A^2 product may be applicable/useful to estimate
gravitational effects on other then the levels/magnitudes/domains
where G is currently measured or tested at. ..........[snip]........
we may have a demonstration and example of the HUP,
manifesting itself here in the uncertainty of either G or N_A values.
........If so, then only the unwieldy product of G * N_A^2 may be of
or may have a "fixed +/-" determinable numerical size/value,
but either one of each one, the N_A or G values alone, may only
be knowable in its accuracy at the expense of the accuracy of
the other one. ... Classic HUP gig??..........However, since this
G * N_A^2 is having the size of ~ 10^40 cm^3/(gr*s^2*mol^2),
I won't loose too much sleep over it......unless someone discovers
a new amplification mechanism thru which this product shows
.....up measurably in astronomy astrophysics or cosmology
............will see! it would be rad!.......ahaha.... ahahahahanson
[Rick]
The point that even some Mensa people just seem to have a
mental block about, with regards to physics is this.
[hanson]
The only thing your 2 liner tells me, Rick, is that you don't like Mensa.
Cool, me neither, because a cute, loudmouthed secretary dragged to
a few meetings. I got the impression that they all were loud mouthed
people united by 3 constantly displayed/uttered fetishes: -- to have the
last word -- to snicker behind each others backs -- to declare everybody
as being stupid. Actually, the word "stupid" dominated all their discussions.
Hence AFAIWC, it also specified the atmosphere of their gatherings.
[Rick]
Forget the values for one minute.
[hanson]
But Rick, if you forget values, even for a minute, then all you
can do is to philosophize, not for a minute, but for as long as you
live. The work in, & the purpose of physics is to physically
*measure* values of real things. You can't forget that.
[Rick]
Well what fundamental property of nature, that is exactly
relative to this bar of yours, caused you to choose such length?
[hanson]
...."this bar of yours"........ahahahaha.......that bar ain't mine, Rick.
hbar = h/2pi, is the standard symbol for the Planck constant and
it's value. hbar is not a length, Rick. h & hbar are "actions", i.e /\E*/\t.
Now, Rick, let's look for more such gems of value you have generated
in your post, for they are of great pedagogic value.
[Rick]
...if we accurately measured all known qualities of the
Hydrogen atom, and created a new set of measuring units
[hanson]
"we"?....well, THEY did that already. Look up Bohr, Fock, Hartree etc ,
They did what you suggest about 80+/- years ago.
It was a big deal then & it still is. -- Unfortunately, when you want to be
more accurate then they were, then mother nature herself comes and
****s with you. To measure the radius of the Hydrogen, "accurately"
is no mean feat. That gossamer thing is so fidgety that the moment you
try to measure it, it ****s you and shows you a slightly different value.
And there goes your "accurate". That is because of the inherent HUP,
Doppler-, Magnetic- and lots of other effects.
Besides, what is *your* measuring stick for "accuracy" made of?
[Rick]
then would those values not also directly apply to all
other atoms?
Yes they would.
[hanson]
Ok, ok, Rick, but you answered your own question. Cool.
It is important to believe in one's own weltbild. Selling it,
is of course another matter, but you should not worry too
much about it as long as your own view makes you happy.
[Rick]
Newton, needed a meter stick.
[hanson]
But, Rick, so did Albert, and to boot, Einstein's dick grows shorter
when called into action. His dick had a little tag, labeled "gamma"
attached to it. Fancy, fancy!
[Rick]
IBM needs a motam.
[hanson]
Right, Rick, but IBM is more interested in the revenues from
their investments in motown. I am absolutely sure about that.
Here you can see how the money *******s do it:

[Rick]
The CO24 for time travel, based on dual singularities,
and gravity distortion, needs a motam.
For accuracy. Otherwise you could end up anywhere.
In the multiverse, 8 decimal places is like horseshoes,
and handgrenades. Close just don't make it.
[hanson]
Sure, Rick, if you say so. I have unfortunately little experience
with your CO24 Carbondodecatetroxide, but if you have some, you
should peddle it to Baikonur, ESA or NASA. You could make a
fortune, dude. However, I would not tell them about this CO24
relationship to horseshoes and handgrenades you have mentionned.
Homeland Security might come looking for you on that.
So, Rick, sshshshhhhhhh......
[Rick]
So once you create a new measuring stick, you use the
same formulas to transpose those measurements to other
things in physics, and voila, if it don't all work out
to be exact. Because the relationships between forces,
and between things, are exact.
[hanson]
Yeah, yeah, Rick tell'em... all of them! But, you must be very
convincing Rick, because they will sing and swing back at you
with their HUP, not a hiccUP, but that Heisenberg gag....and
then they come after you with them ****ing "re-iterations" which
let you dance all over the place, after starting out from the same
spot in the very same direction......It's a horrible mess, trying
to be accruate, Rick.
[Rick]
As exact as copper is copper, and lead is exactly lead.
And a big pile of pure lead, is still exactly lead, just
as one atom of lead, is still exactly lead.
[hanson]
But, Rick, here they will beat you to a pulp with their ****ing
**isotopes**, man. There are so many of them, ....terrible!
Most of them shine and sparkle, man, and the next thing you
know, when you thought you just looked at a copper atom
the ****ing thing has turned into nickel or zinc. All by itself!!
Worst of all, there's nothing I know of, with which we could
stop that unruly behavior. It's horrible, Rick. If that weren't bad
enough, they'll drag to you an accelerator were they shoot them
nickel, zinc, copper or what ever atoms around, and if their
speeds, their energies are high enough then they look all alike,
like a bunch of ****ing protons and neutrons coming down the
pike. Well, I am not quite sure though about whether they are
****ing. But, never the less, it is a ****ed situation.
[Rick]
The smallest units of measurement is Plank length.
[hanson]
Well, again, if you say so, Rick. But, listen man, if you don't tell anybody
I'll let you in on a secret and I'll show you a much, much smaller
length unit. But, you must swear silence or hope to die. Right? -- right!
So, let's cook one up, right here, really quick.
Consider the Kerr event horizon for the mass of the electron, which
gives you a length that you can use as another "smallest" unit with
*** l_e = m_e*G/c^2 = 6.76E-56 cm ***, then for good
measure throw in the finestructure constant (a), to give it some
flavor and flair and you get:
*** l_a = m_e*G*a^4/c^2 = 1.94E-64 cm ***
which gives you a new unit length l_a that beats the ass of your Plank length
*** l_pl = sqrt (hbar*G/c^3) = 1.62E-33 cm ***
by more than 31 magnitudes. Now, the news is that l_a is by far not the
smallest unit length that you can construct. Try it yourself. It is great fun.
Report back with what you have cooked up. PS, the same way you can
make pitifully small units for mass and time...all going down, down...
to anywhere you wish.
[Rick]
Using plank length and c, you can meausre the force of
gravity. A gazillion times more accurately than with
a set of balances.
[hanson]
Sure, that's no big deal, formally and theoretically.
l_pl = sqrt(hbar*G/c^3) -- G = l_pl^2 *c^3/hbar --
F_G = G * m*M/r^2 --- but how does your gazillionically
improved experimental setup look like? I mean the hardware!
To make things worse, F _G = G * m*M/r^2 may actually be
F _G ~ G * m*M/r^2..........so much for the gazillion accuracy.
It's a hard live, Rick, and so inaccurate!
[Rick]
If you read this message enough times, you will understand
if you do not understand already.
[hanson]
Of course, Rick, I did and do understand you...... I did, at once.
And you know what, Rick? ---- You are absolutely right with your
point of view, from your point of view and FOR your point of view.
....which is really all that should matter to you anyway!!!.
And if that doesn't do it for you the you should check into the easy
life of these fat ****s again :
http://www.foulds2000.freeserve.co.uk/economists.htm
You are a good man, dude, have fun and
take care,
hanson
