I must take issue with your
metaphor of relativity. This is where I think physics education fails.
We as physicists try to describe the "really tough stuff"
with one or two metaphors. Unfortunately, it tends to be the case
that we use the same metaphors over and over again because these are
the only ones that work. Most others tend to miss the point. Moreover,
acknowledging that these are metaphors emphasizes their shortcomings,
one cannot necessarily extrapolate the metaphor to gain more insight
into the problem at hand.
The classic example of
this is the "expanding universe as surface of a ballon".
The inevitable question is "what does the inside of the ballon
corresond to in the real universe". The answer to that is NOTHING.
That's where the metaphor fails.
In this sense, I think the relation of thought to special relativity
(as in your metaphor) is not correct. First of all, the aspects
of consciousness that you describe are far more complicated than
relativity. Moreover, as you acknowledge, the metaphor fails when
confronting the symmetric nature of the observer/observed in special
relativity.
How do we, as educators
of physics and otherwise, feel about the extensions (or mis-extensions)
of our metaphors and toy models? What can we do to keep them from
being misinterpreted?
Cheers,
Joseph
