He claims that when we say that there is nothing in physics which would
make such a low-frequency photon impossible, ..

The main purpose of newsgroups such as this is to help people understand
the physics.

We've tried .. the valid physics has been carefully and unemtoinally
explained .. all we get back is insults. If he post physcis, I post physcis
only in return. I've not had to do that much lately.

that we talking about it is not sane or valid physics ..
We can educate him can't we?

No. We've tried. Believe me .. you know what they say about old dogs
though :(

The trick is to give an example so simple that it is easily understood.

We'vetried all the tricks. If you think you have a new trick, then be my
guest .. you'll immediately be called a parot imbecil, theif crook bump
parasite psychopath.

... we can only talk about photons with frequencies 1Hz or more because
that is all we have measured. You've now said what appears to be agreeing
with him ...

I'm at a loss to understand how you came to that wrong conclusion. I was
agreeing with you and disagreeing with him.

I know how hs brain works .. he'll latch onto "It has nothing to do with
physics" and claim that you agree that such photons are not valid physics.

Give me a 1 Hz photon traveling in the +x direction as measured in the
inertial frame S. Now transform to the inertial frame S' moving in the -x
direction with any speed you'd like. Observer's in S' will measure a
frequency lower than 1Hz. The faster S' moves with respect to S the lower
the frequency will be measured in S'. Do you disagree with this?

I don't .. no. He says that he inisits that doing that is just arm waving
and trying to distract from his point. But he listened neough ot modify his
postulate that the lowest frqequency is only for light whose source is in
the same inertial frame as the observer. Goalpost shifting at its best.

....(he will see it that way) .. that it is invalid physics to talk about
low frequency photons. Its not invalid .. its just not terribly useful
:)

1 + 1 = 2 is not useful to me tonight. But that doesn't mean it will
never be useful to me in the future, right? :)

:)

And you already told him that you can transform into another inertial
frame moving with respect to the frame in which the photon has 1 hz
frequency to another in which it is as low as you'd like it to be as a
result of Doppler shift, right?

Yeup .. done all that.

Since it was so easy an example it makes sense that you had already done
that. Good work Jeckyl! If he rejected that then I'd leave it alone if I
was in your place.

I'm happy to leave it alone .. he just keeps poisting over and over about
these 'superfarts'.

I know that its difficult not to respond to someone who is hard to get a
point across to. But, of course, that is your choice. I wish you could
benifit from my many years of useless arguements.

:)

He doesn't even accept that there is no such thing as a lowest real or
rational number greater than zero.

I take it you explained it to him of course.

Of course

Have you tried a graphical approach?

Difficulat in a text based newsgrup

Perhaps he's a visually thinking person who can most understand a concept
if he is able to visualize it.

I don't think he is a 'thinking' person at all :):)

He uses that as justification for saying the all frequencies are a
multiples of some lowest possible frequency (which he was claiming to
be 1Hz at one stage)

Eeek! :)

Indeed

Porat has definitely insulted me in the past. But he's one to let bygones
to be bygones, or perhaps he simply forgets.

I'd go for that latter. There is no evidence of the former.

[snip interesting story]

Best wishes
