Probably more like because you actually studied physics. :-)
What do you call the photons that aren't coupled with both an electric
and magnetic field? Or no field at all, for that matter, such as
exchange particles inside molecules?

I've always wondered if you Yanks wished it was light amplification by
Zowee! emitted radiation, just so it'd be spelled 'correctly' :-P

I think Cray used propylene glycol (anti freeze) at one point,
but I might be mistaken.

There are no particles that are not coupled to a field, if at least one. It can
be electric, magnetic, strong force, weak force, gravity,...
In any molecule, the "exange" particle is the electron.
In a nucleus, you have several of them, some that are extremely heavy,
contributing to the strong or the weak force. When I say extremely heavy, I mean
that some are heavier than the whole atom! As strange as it can look.

It's a good termal medium. Easily available, cheap, good termal capacity,
non-corosive, non-conductive, relatively low dielectric constant to reduce
parasitic capacitance. It's very plausible.

Well, as I said, I didn't call them photons.<G>
Exchange particles inside molecules? I'm not a physicist, and never
studied that far. I didn't know that was either electric or magnetic, so
I'd expect they'd have another name for them. Can you give me an idea of
such a phenomenon?

With words like "jazz", "pizzazz", "razzle", "frazzle" and "razzamatazz" in
the lexicon, there are too many zeds / zees buzzing around and not enough
flyswatters.
Ugh. Just remembered "Zazzle". <shivers>

I'm a geek, but I am constantly astonished by the other people round here...

Not sure on any official definition, but it determines the capacitance
between two surfaces at a given voltage.
The formula for capacitance between two plates is something like C=eA/d,
where A is the area of the plates, d is the distance apart, and e is your
dielectric value of the material between the plates.
Obviously for some situations you need to maximise C, in others you need to
minimise it...

Me neither, really. I just meant whatever excange particles cause (for
exmaple) proteins to fold properly and H2O to work while H3O doesn't,
and so on.
