For technical reasons, measurements of length contraction are all indirect, 
since the only objects we can accelerate to relativistic speeds are elementary 
particles.

Given this caveat, indirect measurements of length contraction abound.
1) The RHIC accelerator collides heavy nuclei. The MEASURED dynamics of 
   the collision matches the results expected if the nuclei were Lorentz 
   contracted by precisely the amount calculated.
2) The magnetic force between two parallel current-carrying wires is due to 
   Lorentz contraction of the current of electrons relative to the static
   charges in the wires. The MEASURED attraction/repulsion *precisely* matches
   the calculated calculation. This is an *easy* measurement.
3) Length contraction and time dilation go hand-in-hand. A mere shift in 
   frames will convert observed time dilation into observed length contraction.
   For example, in the frame of the Earth, time dilation accounts for the 
   anomalously high flux of cosmic-ray muons relative to what otherwise might
   be expected on the basis of their half life. In the frame of the muons, 
   they distance that the muons travel is shortened. The same gamma applies
   to both. Time dilation in our frame is equivalent to length contraction
   in the other.
4) Analysis of particle collisions in accelerators can be explained only if
   one applies the full Lorentz contractions. One cannot pick and choose, 
   accepting only time dilation without accepting length contraction. BOTH
   are required.

As I see you don't actually measure the length. You calculate it from the time and using Lorentz transformations. Of course it will be contracted.

So about Einstein's thought experiment, I know why we argued so long with no results:
I was trying to follow the experiment using Newtonian Physics, because that's what I thought they had available at that time before Einstein came up with the Theory of Relativity, and by Newtonian physics it didn't make sense, because that assumes time is absolute, and t(A) would be = t(A'), also t(B) = t(B').
And you guys kept arguing with me based on Einstein's theories and saying that the length of the train will be different, using Lorentz transform, etc. Obviously if we assume length contraction and time dilation, you reach to the result that in (M')'s frame A' and B' are not simultaneous.
So in both cases what we want to demonstrate, we already use in the assumptions - circular reasoning.
That's why the whole experiment is not proving anything, so it's useless.

You guys said to look at real experiments proving it - that's another thing.

It is TRIVIAL to construct a simple apparatus out of wood, nails and wire
that will measure the magnetic attraction/repulsion between two coils to
within a few percent. As a former high school science fair judge, I've seen
it done.

From the MEASURED forces generated between the two coils, one can easily
deduce the length contraction between the current-carrying electrons, and
one's MEASURED result will agree with that calculated by applying the
Lorentz transformation.

Nobody is going to perform an optical measurement of the distance between
the ends of a meter stick speeding at 0.1 c. That seems to be what you are
insisting on, and it isn't going to happen. That speeding stick, if it 
hits anything, will, I imagine, unleash energy equivalent to a nuclear
explosion.... hardly suitable for a high school science fair project.

But I have personally seen science fair measurements of length contraction 
for electrons flowing at millimeters per second!!!

You miss the entire point of the thought experiment!

It does not prove anything. It is merely a device
to help determine the consequences of certain assumptions.

Then real scientists make real experiments to confirm or
disprove the theory by testing whether the predicted
consequences happen.

As a result of Einstein's gedanken experiment, he came to
two consequences:
length contraction.
time contraction.

It is extremely hard to perform the train experiment
in reality. But one consequence that has become easy
to test is the time dilation effect. Atomic clocks
are now accurate enough to measure the time dilation
due to traveling at speeds that are only a small fraction
of the speed of light.

Other experiments show the effects of relativity
culminating in the experiments supporting General Relativity.

Many of these experiments show that Galilean mechanics
cannot explain the results.

Hopefully this helps you understand the results of
the train gedanken experiment and the PURPOSE of it.

HTH,
ed

Imbecile, 

The train of electrons in an undulator is indeed length contracted. I could direct you to the link but your bias is precluding you from learning anything, so continue to embarrass yourself.

No, that is incorrect. In the first example cited, for instance, what is
being measured is nuclear density. Density as you know is mass (or energy
equivalent) divided by volume, and volume is related to length cubed. So if
one of those lengths decreases, then the density if the nucleus increases.
By measuring something that is highly sensitive to density, then you have a
measure of the change in length. Thus is ESPECIALLY true if you have a
theoretical prediction of how much the length changes, hence you have a
prediction how much the density changes, hence you predict how much the
sensitive “density barometer” will change. Then you just measure that
barometer change and see if it matches the prediction. This is standard
experimental science, which I gather you are kind of new to. 

The other probes are similar.

What is a "direct" means of measurement? Did WWII battleships measure
distances to targets by laying out meter sticks end-to-end? NO!!! They
used optical rangefinders to measure the angle needed to bring two views
of a target into coincidence.

Do laser rangefinders measure distances to targets by laying out meter
sticks end-to-end? NO!!! They measure the TIMES between emission and receipt
of a laser pulse, and deduce distance to target using a math relationship.

Did submarine commanders in WWII measure distances to targets by laying
out meter sticks end-to-end? NO!!! They viewed the image of their target
in the periscope view, and from known and/or typical dimensions of their
target (or class of target), they calculated distance to target.

These are all *INDIRECT* measurements. None of them are examples of laying
out meter sticks end-to-end. None of them represent stretching a tape
measure from one point to another. All of them rely on ASSUMPTIONS used to
DEDUCE distance from the results of other forms of measurement.

They are. Routinely. To various degrees of precision. Some methods are of
sufficient precision to discern relativistic length contraction, others are
not. If you use a camera and a ruler on the ground and a passing horse,
that method will not be if sufficient precision to discern length
contraction of the moving horse. But it is of course completely possible to
measure the length of the horse regardless.  

To measure a moving object with sufficient precision to discern length
contraction takes more care and elaborate design. Of course. 

Now, there are some people who will say foolishness like “I will not
believe until you can explain how to measure length contraction simply,
using only things I can find in my kitchen.” That’s as idiotic as denying
the existence of atoms unless they can be seen with a magnifying glass and
a bright light, or denying the existence of supernovae unless one just
happens to light up the night sky in our galactic neighborhood. 

Only a fool insists that physics claims are only true if they are simple,
common, and obvious to the naked eye.

The alternatives:
1. Time Dilation: A clock second is not a universal interval of time. It contains a different amount of absolute time in different frames. For example: one second in the observer’s clock is corresponded to 1/gamma seconds on a clock moving wrt the observer.

2. Length contraction: There is no material length contraction. Instead the Lorentz’s contraction equation means that the light-path-length (LPL) of a moving meter stick is contracted by a factor of 1/gamma. This prediction is based on the assumption that the LPL of the observe’s meter stick is its material length.

3. A paper on the above concept of time dilation and length contraction is available in the following link:

Mere assertions. Show us that you can calculate something correctly that
SR and GR do not. For that matter, show us that you can calculate ANYTHING.

My theory has the same math as the LT. You asserted that there is no alternative to the Einstein’s length contraction and time dilation and I showed you the alternatives.
