:D I said that the two m's aren't the same. And sure, I also said that
there are variables and constants. It wouldn't make sense if E would be
a constant ;), so I don't understand the problem.

And why should "equations which are not definitions" be true, resp.
what's the problem with equations? For me it doesn't make sense. A
definition is done by an equation.
