People
who actually work have less time to spend at the library than
scientists and other people who spend large amounts of time at the
library. Secondly, small town libraries do not have much other than
books for children and women.

You have not heard of interlibrary loan? How many excuses can you
offer for not wanting to get out of the house and walk a half hour to
look something up?

I don't need to look it up. If there was something to look up, you
could put it here in sci.physics.relativity.

No, I don't think that's an accurate statement, Bobby. You want
everything spoon-fed to you here, and you can't think of any reason
why people can't do that for you. There is a reason (several in fact)
why it is in the library and not copied for your convenience in
Usenet. It would be a copyright violation, for one thing; are you
asking people to break the law just because you don't want to walk a
half hour to the the library? Secondly, there are equations and
figures that are important to the expression of the result that are
difficult to render in ascii; to you want to shoehorn a presentation
into an unsuitable medium just because you don't want to walk a half
hour to the library? If you find it difficult to understand why the
world is not laid at your feet without you having to remove your rear
end from your chair, Bobby, I can understand why you are in such a
state of mental torpor. I don't find people that are so lazy that they
don't understand why things aren't delivered at their feet to be very
worthy of sympathy, do you?

Since you cannot,
obviously there is no need to go to the library.
As far as what I did in the military, people in the military do not
have a choice about what they do.

Did you accept the pay from taxpayers?

I did have a choice about what I
did when they put me in the psychiatric ward of a V.A. hospital. I
escaped.

Did you escape because you didn't want to cost the taxpayers any more
of their money?

Did you escape along a paved road or a sidewalk that was paid for by
taxpayers?

Are you on city water or did you dig your own well?

If you really don't want to accept any money or services from a
corrupt government, Bobby, I can suggest a solution. It will require
getting your rear end out of a chair, though.

The farm where I live has its own well. �The part of the farm that is
now in tract houses supplies water to the city from the wells that are
on that land. �A couple of weeks ago I did some welding on the well
casing for the farm well while they were changing the pump. � Why is
it that you think all people just sit and wait for government money
the way you do?

Well, personally I don't anymore, just like you. I'm not funded by the
government either, though I'm a scientist. You see, there are
scientists who are not funded by the government, too, and they're
doing good work. Perhaps you didn't know that.

� � I escaped from the V. A. hospital because they had no legal reason
to hold me there. �According to the paper work, I was free to leave
any time, but the only way I found to leave was to escape.
� � What is your reason for wanting to discuss these things in a
newsgroup about relativity?

Well, Robert, we're getting around to how relativists are funded,
which is appropriate for this group, I think. And since you really
don't care one way or the other whether relativity is correct, it's
more constructive to have a conversation about something that does
matter to you -- how your taxes are spent.

Well, I would rather discuss relativity because I think I may have
found a way to explain it to scientists using the Michelson-Morley
apparatus.
Consider the arm of the Michelson-Morley apparatus. According to
the experimenters, they were going to measure an ether wind, the frame
of reference of the ether being S, the frame of reference at rest.
The interferometer was moving relative to S, so the frame of reference
of the interferometer was S'.
Light was directed down the arm of the interferometer to a mirror
at the end of the arm. The interferometer was moving with a velocity
of v relative to S, the frame of reference of the imaginary ether. So
if the light was emitted at x=0, x'=0, t=0, then the light would
travel down the arm of the interferometer to the mirror where it would
be reflected back the other way.
Since we already know that there was no ether, S is just a frame
of reference at rest that the interferometer is moving with a velocity
of v relative to. In S, the photon travels a distance of x to the
mirror, is reflected, and travels back to the origin of S. If t is
the time it takes a photon to travel a distance of x, then the total
time for this to happen will be 2t.
From S' if we consider the same events, a photon leaving the origin of
S, traveling to the mirror, being reflected, and returning to the
origin of S, the time will be the same. t'=t.
However, we are using a cesium clock in S' to measure the time of
events. We know from experiment that a cesium clock in S' will show a
slower time than an identical cesium clock in S. I will now explain
why. A cesium clock in S' shows light to be traveling at c in S'.
The origin of S is irrelevant to measurement of time in S'. In S',
the light is emitted at the origin of S', travels to the mirror at the
end of the arm of the interferometer, is reflected, and returns to the
origin of S', all at a speed of c as measured by the cesium clock in
S'. So it is the time that the light reaches the origin of S' that is
relevant to the experiment, not the time it reaches the origin of S.
I will try to keep this explanation simple enough so that even
scientists cannot misunderstand it. The Galilean transformation
equations show that the distance from the origin of S to the mirror is
greater than the origin of S' to the mirror when the light reaches the
mirror because S' has traveled a distance of vt while the light was
traveling from the origins to the mirror. x'=x-vt. If the light is
traveling at c in both frames of reference, then less time has
transpired in S' than in S when the light reaches the mirror. The
light is reflected and its velocity becomes -c relative to the two
frames of reference. When the light reaches the origin of S', the
time that has elapsed in S' since the light was first emitted is less
than the time that has elapsed in S because if the light were to go
all the way to the origin of S as seen from S', the times would be
equal. But the light has not gone that far. It has only gone back to
the origin of S', so the time in S' is less than the time in S at that
moment in that place.
I hope I have explained this simply enough for scientists to
understand. This does not require relativity of simultaneity. It
does not require a length contraction. All it requires is two cesium
clocks which are both showing light to be traveling at c=186,000 miles
per second.
