What does a quark, a photon or a gluon look like? No one knows for sure
but Jan-Henrik Andersen, an artist at the University of Michigan in the
US, has created a series of visual images of elementary particles based
on conversation with physicists at Michigan. The work was exhibited at
Fermilab in the US during the summer and is highlighted in the latest
issue of Symmetry magazine.
To produce the images Andersen worked with David Gerdes, an
experimentalist, Gordon Kane, a theorist, and Sherri Smith, dean of the
School of Art and Design at Michigan. The goal of the project was to
represent particles in a physically accurate way while being visually
appealing and technically feasible.

Awesome, Sam!
Hey Andy, I hope you are seeing this.

Yowie zowie! Check out the photon from Andersen's website!
http://www-personal.umich.edu/~janhande/sizedmatter/standard_model.htm
Two wavelengths long and a 4pi twist just like we predicted in,
http://vacuum-physics.com/QVC/quantum_vacuum_charge.pdf .
So "someone" is thinking like we are. And with the "energy density"
concentrated towards the outside of the "volume". Bingo!!

"Visually appealing"? I suppose that makes some sense, but ...
Briefly, if one wants to look at an object, one bombards
it with lots of photons (a 500 nm 5 mW CW laser generates,
at least theoretically, about 1.259 * 10^16 photons per
second) in a certain energy range. The detectors -- in
our case, the Mark I eyeball -- then pick up the reflected
light and process it in certain interesting ways, among
them focusing the image on a detector screen, namely,
the retina.
One can augment this process via various means;
the simplest is through such items as telescopes,
microscopes, film, projecters, and now digital capture,
computer processing (e.g. false-color imaging) and modeling.
AFAICT, the Orbitron is arguably the simplest method of visualizing
such things as electrons, poor as it is (but it's one many people
can get to easily from webelements.com); there's another variant
which is more accurate (because it's "fuzzy") but I can't remember
its name, and it's problematic anyway; the minute one gets a photon
in there the electron gets bounced out, if the photon's anywhere
near being small enough to resolve the atom with more precision
than feeling a tiny grain of sand under an automobile tire. (An
atom is about 2 * 10^-10 m in diameter; a photon of visible light
is about 5 * 10^-7 m in wavelength.)
Quarks and gluons don't last long, and photons are what we use
to look at stuff and travel way too damned fast to get a
good look at anyway.
In this case, apparently, these might be considered
iconic -- a representation of the real event that can
be somewhat understood by the casual reader. It's a
more sophisticated variant of the "ball-and-wire" atom
models one occasionally sees in such places as physics
textbooks and webelements.com, and it may lead to erroneous
conclusions if one's not careful. For example, the up
and down quarks look like they could "screw together",
making a particle; however, the combinatorics are far
more complicated in real physics, yielding such things as
protons (uud), neutrons (udd), Higgs bosons, pi mesons,
etc.
Still, they're rather pretty. I could see somebody making
plastic models for kids use -- the general idea would be
similar to "cat's-eye" marbles, only these wouldn't be
spherical -- but the kids wouldn't be able to do much with
them except use them as shooters. (But then, isn't that
sort of what we do with real particles anyway, in accelerators
such as the LHC? :-) )
It's an improvement, perhaps, over http://quarkdance.org, since
it's more serious. Maybe it depends on one's tastes; not everyone
likes polka music. :-)
