Like whittling, it is less the shavings or the resulting sculpture
than the process that entertains. The willfully stupid deserve to be
crushed as a flush toilet is more than a receiving vessel.

I make no claims as to validity of QM, nor does QM. "The math is only
metaphor." Nevertheless, one cannot fault single photon two-slit
diffraction with a coincidence argument. The intensity over time can
be reduced to arbitrarily small values and the two-slit diffraction
pattern still evolves by the book.

It doesn't have to be a vacuum slit in an opaque barrier, does it?
What about two local implanted microstrips of substantially altered
refractive index? Easy to do with semiconductors and IR light.
 
A single photon approaches a double slit. Would you be happier with
Many Worlds wherein half the time it passes through each slit
discreetly and the two possible futures interfere with each other on
the other side? Or a single photon passes through one slit and its
mirror image in jellium or whatever goes on to be naughty? Then, do
dielectric slits with very large work functions (very deeply buried
HOMOs) give altered patterns? Or Heisenberg does his thing and you
cannot determine which slit passed the photon - they both did. Hence
quantum eraser and quantum double eraser experiments.

A bigger problem is the use of single charged particles re de Broglie
waves or much bigger lumps re C60. Arguing photon subtleties is one
thing. Putting C60 through a double slit experiment is something
different. Why stop there?

Consider a suitable double slit, array of slits, zone plate, whatever
whose elements are alternate Peltier heater/cooler materials. One can
now have alternating hot and cold slits on a very small scale. Take a
fluxional organic molecule that rearranges to itself with permuted
atom connectivity like bullvalene (slow) or semibullvalene (fast).

Make a nice collimated molecular beam, attenuate intensity to single
molecules, and shoot through the hot/cold slit array. Have the temp
of the molecule of choice be sufficently high that it rearranges
several cycles during its passage through the slit. Will its phase
coherence decohere as "one half of it" passes through a hot and cold
slit with different rearrangement kinetics? OK - what comes out the
other side when the two wavefunctions recombine into an observable?

Ditto a beam of resolved chiral molecules in two-slit diffraction. Is
chirality retained after recombination? One can make a very strong
argument that things will go sour via Hund's paradox,

F. Hund, Z. Phys. 43, 805 (1927)
http://arXiv.org/abs/cond-mat/0203017
http://arXiv.org/abs/quant-ph/0303024
http://arXiv.org/abs/quant-ph/9908008

Certainly one could micropattern alternately chiral slit material and
relieve two-slit symmetry that way. Will the result be a one-slit
patern?

It requires more than an idiot to understand it, even to maunder about
it afterwards. We'll see how it fares in sci.physics.reaserch.

Has there been any criticism of the results, experimental or
theoretical? They went on to use C70, polyfluorinated C60, and say
they wll attempt a small virus.

Fair enough. Undeniably there were a large number of excited
vibrational and rotational modes at molecular beam furnace temp.
Probably some low-lying optical modes, too.

All is quiet. The first hemiparity Eotvos experiment, optically
right-handed quartz vs. fused silica, was running a perfect null. The
balance and test mass configuration are shown to have no extraneous
outputs. The full parity Eotvos experiment is next, left-handed vs.
right-handed single crystal quartz. We lost our left-handed single
crystal raw material to an autoclave rupture. That puts off obtaining
the next one until about April. Attempts to source natural
left-handed quartz went poorly vs. the six kinds of twinning.

If spacetime is achiral (metric gravitation) all three experiments
will null. If spacetime is chiral (affine gravitation) then ordinary
test masses and one extremal parity test mass will be low energy
interactions - like putting a sock and a left shoe on a left foot.
They slide right on. The other extremal parity test mass will be the
high energy anomaly - right shoe on a left foot.

We might guess that spacetime would be left-handed re parity breaking
in the Weak interaction. The *geometrically* right-handed parity test
mass would then be the anomaly. Due to opposite directions of
property definition, commercial optically right-handed quartz is space
group P3(2)21 geometrically left-handed. The full parity Eotvos
experiment is the deciding observation. Hurry up and wait.

Arguments about Hundt's Paradox re chirality and Green's Function re
anomaly sourcing are laid to rest in qz.pdf below, in two appendices.

Hyper-Right Wing Uncle Al has no problem doing science with PR China
or Force Frappe nannies. Ditto Canada (the horror), Germany (about
those camps), the UK (vegetable oil allowed in chocolate), Switzerland
(perfectly amoral), Belgium (Penal Code, Article 561, para. 7), or
anybody else who has fast CPU-cycles to volunteer. If this thing
works our respective parent countries can make public asses of
themselves on their own nickels. If not, then 12 gilded paperweights
can be auctioned on E-Bay.

My end is currently crunching a second generation extremal parity test
mass,

Single CPU data finishes by second week in February (including a week
in an Athlon 55FX/2.6 GHz with 2 GB Corsair Xtreme DDR RAM on an ASUS
"A8V Deluxe" K8T800 Pro Chipset motherboard. Goody). If anybody has a
cluster that is not doing anything or needs to have a defective node
located...
