Right. Then Stachel goes on to describe how Einstein solved the problem.
Valev, however, is not interested in solutions, he is just interested in quotes
which he thinks support his own warped view of the world. Only fools like him
who cannot read would think that.

Not true. Valev didn't even read the text he quoted above: "THERE ARE
RELATIVISTIC CORRECTIONS" [emphasis mine] -- they are negligible for sound (the
subject of the quote), but not for light. Dr. Fendley is honest in mentioning
them; Valev is not honest at all.

Only in Valev's fantasy world. In the world we inhabit, we OBSERVE that both
frequency and wavelength vary for an observer moving toward the source, such
that the (vacuum) speed of light remains c. Valev's fantasy, which is NOT
OBSERVED, has no physical meaning at all.
Note to readers: Pentcho Valev is among the most persistent
idiots around here. He has been repeating this nonsense for
many years, without any attempt to learn the subject he tries
to write about. I reply to him only occasionally, as a service
to readers who may not recognize his mistakes. He has proven
himself to be unable and unwilling to learn anything.
