any equation, properly derived from a basic equation that expresses a
physical law or definition, has an interpretation?

Since c is defined as a constant with a certain value, I propose that
you solve equation (1) for 1:
1 = (u/t)^2 + (v/c)^2
(eq 3)
and thus ...
"It would seem that an experiment could easily be designed to explore
the physical implications of (eq.3). This experiment could easily be
repeated for various values of v and x (where the values of the
variables u and t are recorded, and the value of c is known). In each
case the value of 1 predicted by the data (via (eq.3) ) should agree
with 1."

ROTFL! Kind of reminds me of this little tidbit I kept for posterity:

<quote>
The primary purpose of the DATA statement is to give names to
constants; instead of referring to pi as 3.141592653589793 at every
appearance, the variable PI can be given that value with a DATA
statement and used instead of the longer form of the constant. This
also simplifies modifying the program, should the value of pi change.

Yes, worth keeping :-)
