I wasn't even talking about pigeons .. that was your little flight of

A racer of 50Km/hr pigeons releases 1 bird every 5 min
from a 100Km/hr truck. His wife at the loft receives the
pigeons at intervals not of 5 min but
"a somewhat larger time" You are suggesting the
someone's watch is responding to the motion and
the finite speed of the birds shouldn't be considered.

I suggested nothing related to pigeons

Actually I don't think you ever said the racer's watch
wasn't going slower to explain his wifes observations
so for all I know your sense of reality is as strange
as your maths.

Sorry that you don't undersatnd Sr and Lorentz transforms. Go away
and
study, and come back when you do.

<< It is clear that dt = d_tau in the particle's rest frame.
Thus, d_tau corresponds to the time difference between
two neighbouring events on the particle's world-line, as
measured by a clock attached to the particle (hence,
the name proper time). According to Eq. (1422), the
particle's clock

----> appears <-----

yes .. it does appear to .. because it is running slow (or rather its
projection into the inertial frame is running slow)

How would the pigeon racer make such a "projection" ?

He doesn't have to .. that's what nature does for him


to run slow, by a factor gamma(u), in an
inertial frame in which the particle is moving with velocity u.
This is the celebrated time dilation effect. >>

...Contrary to your arrogant assertions that something
more is afoot than a mere path delay
It is more than path delay .. it is NOT an illusion .. time runs slower
in
relatively moving frames tha ones own frame.
Do you think time runs slower for for the pigeon racer?

From the frame of someone not comoving with him, yes

Will his breakfast last longer so he has extra cookies when
he arrives home?

That is unresponsive. Keep track of the birds released.
Keep track of the clock ticks emitted and absorbed.
And see if you don't find a striking resemblence to
this famous parlor trick:

http://en.wikipedia.org/wiki/Missing_dollar_paradox

Dollars, birds and images of a clock moving from
one mark to another don't just vanish into thin air.
(lovestruck racing pigeons excepted)


Its not an optical illusion that we simply see it slower beacuse of
delays
in the light getting to us from the clock we're looking at.
... and it
works the same for pigeons and light.
Yes .. esp if they are very fast pigeons.
Please .. do some more reading on Lorentz transforms and SR.

I have read the excerpt from U. Texas several times. It says
the same the thing every time ***Apparent***.

Its appearent because it happens .. its not just an illusion. The clock
really is running slower in the frame of other observers. its not that ,
due to the time for the light to reach the observer, it just looks like its
slower. It really IS slower.

If it really is slower then you can substitute birds for clock
ticks an account for each and every bird. I am betting
your interpretation of SR will be in need of a bird hunter

Try reading more than ONE text

You have some formula to take an average?
We could print them all out, weigh them and
rule for the heavier stack of paper.

The text I am reading is used to prepare astrophysicists,
tokamak designers and medical workers. If you find
an error I will make every effort to have it corrected.


Are you
trying to demonstrate another relativistic effects whrere
the words on a page change if you read them enough times?
Words that wear out?

Well .. if you keep reading the same paper over and over without
undersatnding it, then that might happen.

Account for all the birds (or clock ticks) then we can
decide who understands the problem.
