| Perhaps that's your problem.

Nope, your problem.

You are automatically stupid.

Yes, you dumb fuck.
It is at (80,0,0,16) which is not part of the equation.

So who gives a shit about a stationary clock or what spot
you are talking about, since it isn't part of the equation?
(rhetorical question, you are too stupid to answer sensibly.)

You did that by prattling on about a "stationary clock at that spot".
That "spot" is x, not x'.

Yes, dumbfuck.

Why are you trying to do it then, dumbfuck?

|
| Of course not, the equation is for tau(x'y'z't), not for tau(x,y,z,t).

Correct.

|
| Yes. Clock distribution is the basis of Einstein's paper.

Infinitely stupid dumbfuck, there are no clocks in the equation, let 
alone one at 80.

| Not *on* the engine.

Right. There is a "moving" clock on the engine that is at rest with the 
engine.
We call it the "driver's wristwatch", infinitely stupid dumbfuck.


| At every instant the engine passes a stationary
| clock.

Irrelevant, all the stationary clocks are not part of the equation.


| > there is a clock that moves with the engine.
|
| Yes.

Ok, so what are you prattling on about a "stationary clock at that spot" 
for?
Answer: Because you are infinitely stupid.

Androcles.
