Rob,

To add another philosophical layer, you may want to restate your final
comment as 'Reality will prevail'.

It could be said that Physics attempts to model reality based on
observations (a body of organized knowledge about the things and forces in
the universe based on experimentation and observation - if anyone else on
the list was forced to memorize that definition, give me a call and I'll
quote a soliloquy from Hamlet that ought to rekindle some memories). 

Otherwise, we might have to say that 'reality' changed when Einstein came
along (at least the 'reality' as defined by Newton). It probably wasn't the
reality that changed only our interpretation of reality.

Sorry, I am being facetious - but sometimes I can't resist.

Nice examples.

Regards,

-Brett

Sainath

A couple things you might consider, Maxwell's equations work very well for 
describing the average effects of many photons. When you start looking at 
the quantum level effects of small numbers of photons they don't work so 
well. They also predict that TEM waves in free space will propagate in a 
straight line but we know that the direction of propagation is effected by 
gravitational fields.

The question Chris was responding to was a philosophical one, comparing how 
we model reality to reality itself. While we may be able to gain 
significant insight from a good mathematical model, it remains just that. 
Physics will prevail.
