You are automatically stupid.

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


At this instant the
| clock *on* the engine shows tau(32,0,0,16) microseconds.


So who gives a **** 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.)

| But, one step at a time. Let's deal with the stationary spot first.
| That's 80, the engine moved from spot 32 at speed 3 for 16 time.
|
| You now switched coordinates - now you are talking about x, not x'.

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



| The
| coordinate x' is always 32 at the engine.

Yes, dumb****.

Changing from (x',y,z,t) to
| (x,y,z,t) changes the function tau.

Why are you trying to do it then, dumb****?




| 32+ 3*16 = 80.
|
| Does 80 appear in either equation?
| No.
|
| Of course not, the equation is for tau(x'y'z't), not for tau(x,y,z,t).

Correct.


| Did anyone put a stationary clock at 80?
| No.
|
| Yes. Clock distribution is the basis of Einstein's paper.

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


| Is there a "stationary" clock on the engine?
| No;
|
| 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 wris****ch", infinitely stupid dumb****.


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.
