On sci.physics the slightest error counts as a major lapse if someone
with a reputation for precision commits it, while utter drivel emitted
in sufficient quantities is ignored.  :-)

Okay, that's good.

Talking to the wrong people.  I don't think anyone here does Aspect-type
experiments.

A salary in the meantime?  :-)

No, but you just need to find one and convince them to bankroll such an
experiment.  Don't worry, I wasn't under the delusion that YOU had the money.

Thanks, I may look 'em up sometime.

Since I am a mathematician I get my kicks from working to render
compatible the formalisms of general relativity and quantum mechanics
and ponder the many nice mathematical spinoffs.  I would be utterly
delirious with pleasure if I came up with a nice quantum theory that had
classical general relativity as its hbar -> 0 limit.  This would be the
sort of theorem that would make me feel I had accomplished my goals.
The loop variables formalism already hints at such a result but there
are a lot of things to work out.

Since I feel pretty confident that quantum theory and general relativity
have a lot of truth to them, I suspect that a mathematically elegant
unification of them will be physically important, even if it's not the
Theory of Everything, that is, the Truth with a capital T.  It is too
early to say what predictions a good theory of quantum gravity would
make far above the Planck length but there are some interesting notions
such as getting fermions and charged particles from fluctuations in
topology, which might allow a serious simplification in the standard
model and even some predictions.

No point in talking tough.  We made our bet and time will tell who's right.
