I also undertand that he used c+v and c-v in his computation
½[tau(0,0,0,t)+tau(0,0,0,t+x'/(c-v)+x'/(c+v))] =
tau(x',0,0,t+x'/(c-v))

And does the form x'/(c-v), or x'/(c-v) + x'/(c+v)
look familiar?

Sure, and unequal.


Did you perhaps see anything like that when you worked
out the mosquito problem?

Of course. Everyone knows (1/2) * (16+4) = 16.
That's how you prove the velocity of a mosquito is 5 fps
in all inertial frames of reference.
You are a relativist, so you are bound to agree, right?



Didn't you write this?

t1 = 32/(5-3) = 16

Yes, I did.


And this?


t2 = [ 16 + 32/(5+3) ] = 20.

Yes.
I also wrote (well, copied it from Einstein, actually)

½[tau(0,0,0,t)+tau(0,0,0,t+16+4)] = tau(32,0,0,t+16)

In good faith, of course, which you do not seem to have much of,
as you are trying to save face now. The monkey has won, Poe.
Now I'll drool sarcasm if you keep up your idiocy. The question is,
which one is the monkey?



Did you write them so long ago that you can no longer
remember what those denominators mean?

Good grief no. In good faith they mean 5-3 and 5+3.

and said "But the ray moves relatively to the initial point of k,
when
measured in the stationary system, with the velocity c-v, so that
x'/(c-v) = t."

When I went to school, c-v was not equal to c.

And the mosquito is moving, according to a stationary
observer, at 5-3 = 2 m/sec. Yet we started out assuming
the mosquito moves at 5 m/sec, and 5 is not 2.

Ah, but you don't see, the DISTANCE measured by the stationary
observer isn't 64 feet, because 20 seconds (agreed?) * 2 fps = 40 ft
The mosquito is moving at 5 fps in all inertial frames of reference,
but only records 64/5 = 12.2 seconds by his own watch. It's called
time dilation, I'm sure you've heard of it (in good faith).




How, oh how, can we reconcile the 5 with the 2? When I
went to school, 5 was not 2.

Time dilation, of course. Simple, Isn't it?


Could it POSSIBLY be that "the speed in the stationary
system" and "the speed relative to a moving object, as
measured in the stationary system" are NOT THE SAME THING?

Good grief no, the speed of mosquitoes is 5 fps in all inertial frames
of reference. Einstein's mathemagics proves it.
