O'Barr Instructions to Seto.
(This note will try to explain the SR method of
measuring the length of an object.)(This is really
the LET method, but they are the same theory!)
*****************************
A few comments which might inlight Seto further...

END OF MAKING MEASUREMENTS OF STATIONARY OBJECTS!
Or, one can use the operational definition of length measurements of
stationarry objects: Send a light signal from end A to end B of the
object, reflect the light back to end A. Take the time interval
indicated by the clock at A, divide by 2 and multiply by the integer
299792458. The value obtained is by definition the length of the
object.
measure lengths of stationnary objects.From this procedure, one can build rulers and then use those rulers to
But now, everything gets to be complicated if we
find that the object we want to measure is moving.
<SNIP>
Again, one can use the definition of length.
Locate the endpoits of the object at the "same time". The distance
between those two locations is the length of the object. But "same
time" has a particular meaning: It means to have synched the clocks
and note which of our clocks indicate the same value when the edges of
or object coincides with it (clocks).
IOW, set (hypothetical) clocks everywhere on the ground and (einstein)
synch them (with a master clock if need be). One of the ends of our
travelling object will meet the clock at X=0. Call T_o the time
indicated by this clock. Find another clock which indicates the same
value as it coincides with the other end of the object. The distance
between this later clock and the clock at X=0 is the length of the
travelling objetc.
Call it apparent length, measured length or whatever. The above
procedure is the definition of length (in physics).
To see all this, you can start with a true ether
frame, and cause all moving rulers to really change
their lengths, and to have all clocks to really
change their rates, and then to cause all clocks to
physically be synched as required in SR. Once you do
all this, which makes things very messy,
Messy? I find it far less messy that SR's "mess".
but if you
do all these things correctly, you end up exactly
with what is required in SR. Measurements become
exactly as shown in these SR equations, but
everything is really very simple 3-D actions exactly
as Lorentz explained these things.
