No, poor idiot, our senses don't detect any 
coordinates. That's because coordinates are
abstract.

Since your moronic physics stopped requiring their constructs
to be measurable...

No - your idiot guru has proven they don't have.

A lie, as expected from fanatic trash.

With clocks: clock one will accumulate more clock seconds than clock two. This means that the odometer analogy is useless.

Stupid Ken, nowhere in this party of the analogy were clocks mentioned.
He is discussing how you can make different trips from Chicago to New
York, and by doing so, you get different distance measurements by the
odometers.  Odometers strictly measure distance, not time, and they are
not clocks.

What time is it? It's six miles.

You can use a "space-time odometer", ..at the tone the time will be 6 and half miles past 3 o'clock.

most likely a "bad" clock since einstein doesn't really want to measure
the exact time...

but if you combine a light-clock with a space-time odometer..

Get conscious, man. Have you ever seen 2 clocks with
identical readings?
The question is not whether clocks have identical 
indications or not. What matters is: is difference 
between them "proper" or "erroneous".

Clocks ALWAYS differed. And differences in Newton's time
were much greater than now, he surely knew about them.

The real difference between the classical physics and The 
Shit of Einstein is: in the classical physics the diference
between clocks, whatever it was, was erroneous and thus 
ignored. While poor idiot Einstein has "discovered"
that  unsynchronizing clocks are fine and proper.

The ANALOGY is strictly in Euclidean geometry in which there is no time. You are 
to look ONLY at the values on the odometers. Driving speed is irrelevant.

This is true only if a second is a universal interval of time. It is not. The SR math says that a second in A’s frame (or on A’s clock) is worth 1/gamma second in B’s frame (or on B’s clock).

Meantime, in the real world:
-seconds are not miles
-clocks and odometers work completely differently
-while odometers can show different values and it's
okay, ANY difference in clocks indication is an
error (with the exception of clocks from different
zones).

This analogy is obsolete.....it says that the car that followed a longer path will accumulate more miles when they meet again simultaneously. Whereas with clocks the clock that follows the longer path will accumulate less clock seconds.
Better explanation: the rate of accumulating clock seconds is dependent on the speed (absolute motion) of the clock in SPACE. The higher is the speed of the clock in SPACE (the E-Matrix) the slower is its rate of accumulating clock seconds.

At what point in time does the clock run faster? Is it one second after the traveling twin moves? 

Is it one minute after the traveling twin moves?
Is it one hour after the traveling twin moves? 
Is it one day after the traveling twin moves?

At what point in time does the clock run faster?

In other words, 'when' does the clock run faster? Are both clocks the
same time two days later after the traveling twin?


How about a week later? Are the clocks still the same?? Or, are the
clocks differnt times the moment the traveling twin ...travels?


When does it speed up or slow down??? A year later? A second later?  


Or, ....whenever it feels like it.


No one can answer this question cause...no one knows. 


I guess you gotta stop making 'thought experements' and measure it in
the real world.

	[First, as I keep saying, this is NOT ABOUT ONE CLOCK "RUNNING
	 FASTER" THAN THE OTHER -- identical clocks ALWAYS run at
	 identical rates. This is about the total elapsed proper time
	 for each twin between their separation and reunion.]

Given that the home twin remains at rest in an inertial frame the answer is 
clear: NO.

Proof: Use the usual coordinates in the inertial frame of the home twin, denote 
the separation as happening at time T0, and the reunion at T1.
The home twin's clock displays
	\integral_T0^T1 dt sqrt(1 - v^2/c^2) = T1-T0    (v=0)
The traveling twin's clock displays
	\integral_T0^T1 dt sqrt(1 - v^2/c^2) < T1-T0    (0 <= v < c)

	[Since the integrand for the traveling twin is always <= 1, and
	 is < 1 for at least part of the journey, the traveling twin's
	 clock displays less elapsed proper time than the home twin's.]

In the imagination of an insane halfbrain;
in reality, however, it depends.

denote that a man walking a street observe trees and
buildings running around him. And it's obvious truth!
Because a moron said!

If the traveling clock accumulate less clock seconds than the stay at home clock when they meet again.....then the logical conclusion is that it “ticks slower” or accumulating clock seconds slower. The cause of this slower accumulating clock seconds by the traveling clock are due to the following reasons:
1. According to SR: the difference  is due to the longer path length  followed by the traveling clock.

2. According to IRT: the traveling clock travelled at a higher speed in SPACE than the stay at home clock and thus accumulating clock seconds at a slower rate. Why higher speed in SPACE causes the clock to accumulate clock seconds at a slower rate? The answer: The completion of each cycle of the Cs 133 atom is dependent on the arrival of a specific amount of energy from SPACE (the E-Matrix) and this is dependent on the speed (absolute motion) of the Cs 133 atom in SPACE (the E-Matrix).

There is no way to MEASURE the tick rate of a moving clock......the rate of a moving clock accumulates clock second is predicted using the LT.
