Sometimes relativity textbooks are written by Einstein's zombies, not
by Einstein's hypnotists, and in such cases one can find unforgettable
texts. For instance, Einstein's hypnotists often confuse the reader by
introducing a light source that emits flashes at time intervals T and
then calling the quantity 1/T "frequency", in the hope that the reader
will confuse this frequency with the wave frequency (in Einstein's
zombie world the reader always confuses the two frequencies). However
hypnotists never go so far as to call the distance between the flashes
"wavelength". Zombies' reasoning is bolder - they somehow know that
there can be no frequency without wavelength:

Murat Boratav, Ryszard Kerner
Professeurs a l'Universite Pierre-et-Marie Curie, Paris VI
"RELATIVITE" p. 74:

"La source O emet deux signaux successifs separes dans l'espace par une
distance lambda_0 et dans le temps par un temps T_0, qu'on peut appeler
"longueur d'onde propre" ou "periode propre" en ce sens que ces
grandeurs sont caracteristiques du referentiel ou la source emettrice
est au repos."

Blasphemers! How dare they use the word "frequency"
to refer to the number of times per second some periodic
event occurs!

How dare they avoid the word "wavelength" when not
discussing a wave?
