Comments in square brackets are mine.

THERE is hardly a simpler law in physics than that according
to which light is propagated in empty space
[except the Principle of Relativity, a really simple law].

Every child at school knows, or believes he knows, that this
[Harry Potter]
propagation takes place in straight lines with a velocity
c = 300,000 km./sec

[relative to the source, but cosmic muons can win that race by a mile,
literally. Einstein seems to have forgotten he said "we shall, however,
find in what follows, that the velocity of light in our theory plays the
part, physically, of an infinitely great velocity"].

At all events we know with great exactness that this velocity
is the same for all colours, because if this were not the case
[prisms would split white light into different colours and we
never see that, and ]

the minimum of emission would not be observed simultaneously
for different colours during the eclipse of a fixed star by its dark
neighbour

[except that Algol has no dark neighbour, John Goodricke, 18 years
old with a toy telescope in 1782 forgot to include the velocity of
light into his calculations and an eclipse means no light at all,
not a reduction in magnitude, besides which calculations reveal
that such a system is unstable, the "dark neighbour" is at the Roche
limit and will break up]

By means of similar considerations based on observations of
double stars
[Sirius, 8 light years away with a period of 50 years,
http://www.star.ucl.ac.uk/~apod/apod/ap001006.html
no other double has ever been seen]

the Dutch astronomer De Sitter was also able to show that the
velocity of propagation of light cannot depend on the velocity
of motion of the body emitting the light
[oh really? how? I see no significant velocity v from Sirius to add to
c].

The assumption that this velocity of propagation is dependent
on the direction "in space" is in itself improbable

[but factually true. Compare http://www.ebicom.net/~rsf1/sekerin.htm
(fig 3 with http://www.britastro.org/vss/gifc/00918-ck.gif
Real scientists don't deal in assumptions and probables or persuasion].

In short, let us assume
[No, I will not assume]
that the simple law
[because Einstein says it is a law]
of the constancy of the velocity of light c (in vacuum) is justifiably
believed by the child at school
[who also believes in Santa Claus, but not believed by thinking
rational adults].

Who would imagine that this simple law has plunged the conscientiously
thoughtful physicist into the greatest intellectual difficulties?
[and solved them, not being a peanut brain like Einstein, it wasn't that
difficult]

Let us consider how these difficulties arise
[because Einstein can make up stories] ."

[silly train story]

At this juncture the theory of relativity entered the arena.
[Einstein wants to be famous]
As a result of an analysis of the physical conceptions of time
and space,
[insert here this 'analysis' in Einstein's own words]
"we establish by definition that the "time" required by light to travel
from A to B equals the "time" it requires to travel from B to A."
[end insert. Some great analysis, that was.]

it became evident that
[Einstein is lying through my teeth]
in reality there is not the least incompatibility between the
principle of relativity
[which he hasn't discussed at all]
and the law of propagation of light
[Because Einstein says so, it's a LAW, stomp foot]
and that by systematically holding fast to both these laws a
logically [huh?] rigid theory could be arrived at
[such as the speed of light being infinitely great in his theory].
This theory has been called the special theory of relativity
[or the special theory of the excrement of the male bovine]
to distinguish it from the extended theory, with which
we shall deal later.

In the following pages we shall present the fundamental ideas
of the special theory of relativity
[but the conscientiously thoughtful physicist isn't taken in by it]."

Perhaps "Androcles" meant "Roche lobes" and not "Roche limit". My
freshman astronomy students sometimes confuse the two.

"The two stars are so close together, separated by only five percent
the distance between the Earth and the Sun, that the brighter smaller
star produces tides in the larger one. Matter then flows in from the
large one (at a rate of around two hundred- millionths of a solar mass
per year) to the small bright one, the effect directly observed
through the stellar spectrum as the K giant is being stripped nearly
to its core.

Won't tell us how fat you are, eh?

I'm not afraid, I weigh 2.342 milliamps per centimeter on the Richter
scale
(stomp foot) and 5.324 litres of warm air on the Beaufort scale.
I've never scaled my bathroom, I use a proprietory brand of liquid
to de-scale it and I do not own any crampons or tampons. Way back when
I smoked a pipe I scaled that, but now I no longer own a pipe either.

Can't see a longitudinally polarized photon, .."if you won't look";
Look *DiRECTLY* UPstream, to see a longitudinally polarized photon.
ABSORBED photon mass is h*fL / c^2 = nA*{mph}*ls / rA = [mph] = m1.
DiPOLE & AERiAL mass ABSORBED longitudinally polarized AMBiENT emf.

ALL (n - 1) GUESS mass is SUBMERGED mass ..mathematically speaking.
CAViTY DisCHARGE mass of EQUiVALENT ambient = SHELL mass m1, whe
[This is SUBMERGED weight-less EQUiLiBRiUM of m1 in AMBiENT media].

Perhaps, help with UNanswered QUESTiON put to Bilge, over and over:

Angular momentum is [(PLANET-like mass)*(orbit radius)*(velocity)],
..with normal SI STANDARD units of - kilogram*(meter)^2 / second.

Q. WHY is NO CENTRAL mass QUANTiTY in that fundamental equation.?!!

I have a little excercise for Dirty Van of the Motel:

can you bent and lick your aswhole pig? Dogs do that successfully all
the time, why can't you?

When you are done, continue studying the square root function.

Sure :-)

Van Motel,

Why have you resorted to stalking me in other NGs, even though I haven't made a
single post to you or about you in many, many months? Were you hurt that I told
the truth about what a bitter, pathetic, old man you are?

LOL!

Albert Einstein, "Relativity", Chapter 7: "There is hardly a simpler
law in physics than that according to which light is propagated in
empty space. Every child at school knows, or believes he knows, that
this propagation takes place in straight lines with a velocity c=300000
km/s."

Chapter 22: "...the law of the constancy of the velocity of light in
vacuo, which constitutes one of the two fundamental assumptions in the
special theory of relativity and to which we have already frequently
referred, cannot claim any unlimited validity. A curvature of rays of
light can only take place when the velocity of propagation of light
VARIES WITH POSITION."

The rational world would ask: How does the velocity of propagation of
light VARY WITH POSITION? Increases and becomes greater than c=300000
km/s? Decreases? Increase and decrease depend on what?

The rational answer is as Einstein explained in 1916:
Light speed depends on the gravitational potential and decreases with
decreasing gravitational potential, which results in Huygens light bending.
Clock rate decreases similarly with decreasing gravitational potential,
while horizontal lengths are unaffected in GRT. In that way, locally the
quotient dx/dt=c.
