I can be fuckin' nasty too, you ***, but I'm not unfair.

Don't blame me, that's the wrong attribution.
Apparently "Geschwindigkeit", in physik, is what "Geschwindigkeit" is in
mathematik, according to the shithead Einstein who did not know the
difference
between a vector and a scalar.

'c' is clearly intended to be a vector:

but is introduced as a scalar:
http://www.fourmilab.ch/etexts/einstein/specrel/www/figures/img7.gif
and it AIN'T both.

This impedes communications rather a lot, but can't be helped.

Agreed.

Most mathematicians, however, do not ignore the issue since it is highly
relevant,
and a mirror reverses the constant direction of light anyway.

That's why physicists should stay the *** out of mathematics, or learn it
first.
