Chris.

On the trip, did you have a side window or a back window?

I just recall how Hilary and I were picked up one day while we were out in
the country by a flying disk and together we travelled to a star some 10
light years away where we met some freindly intelligent black shiny skinned
dinosaurs with spears and then came back. The journey took as 3 months out
and three months back including the stopover of a few days on the alien
planet and we were away 6 months.

Hilary was easily brainwashed by the local christian gang of thugs into
forgetting the experience and I resisted a bit longer so I was shrinked.

The aliens who flew the disc did not show themselves or were not present and
they were not the aliens on the distant planet we went too.

So the prediction of time dilation is not what we observed. The length
contraction cancelles out the time dilation. Obviously if the distance you
go is contracted by the velocity you get their quicker. (The faster you go
the sooner you get there)

Time=distance/velocity so time taken contracted distance/velocity = distance
x gamma/velocity. Or time=distance/4-velocity.

Momentum=mv/gamma = m * (v/gamma) this is the rule for partial fractions...
remember?

I did say I did not understand it! Do you?

A difference between psychopaths like Sue or Androcles and
sane people is the ability to consider meanings of words

If K is a Galileian co-ordinate system, then every other
co-ordinate
system K' is a Galileian one, when, in relation to K, it is in a
condition of uniform motion of translation. Relative to K' the
mechanical laws of Galilei-Newton hold good exactly as they do
with
respect to K.

"Light always travels at a constant speed in a

Since light has no mass to couple to a gravito-inertial
field, but the original poster persist in advancing
formula as tho it did. The issue is likely more
than just semantics or errors in translation.

I don't understand your objection, Sue.

Light always travels at a constant speed in a vacuum relative to any
inertial frame of reference.

That implies observer dependence.

Interesting. Philosophically I agree with what you said, that the
speed of light is dependent on the observer. However, it is quite
possible to establish a frame of reference with no observer traveling
at that speed. Either way, there is a Coordinate system associated
with Maxwell's Laws, either x, y, and z, or r, theta and phi.

<< In physics, an inertial frame of reference is
a reference frame, tied to the state of motion
of an observer, >>http://en.wikipedia.org/wiki/Inertial_frame_of_reference

It is
with this coordinate system with a point (0,0,0) or (0,theta,phi)
which is either traveling, or not traveling with respect to the
source, or the observer, and it is this point or any other point in
the coordinate system with which the speed of light is constant.

For there to be divergence and curl and all those neato things in
electrodynamics, you have to have a coordinate system, and that's
essentially the same thing as an inertial reference frame.

I don't know if it was your intention, but you've convinced me,
qualitatively, Uncle Ben has given an equivalent statement of this
second postulate, differing only in semantics.

Well, I guess Einstein just wrote that observer
independence in so Uncle_Ben could take it out.
