There's no reason to try to create your own private newsgroup.

This newsgroup is for the purpose of discussion relativity,
so post your theories here. You'll get a lot more readers
anyway.

I assume that by "this nesgroup" you mean sci.physics.relativity, not to
the other crossposted groups (sci.physics and sci.physics.particle).

Very thoughtful.

See if you find some correlation between:

<<How do we distinguish between Local and Global reference frames?

A global reference frame G is defined for referring N particles
contained within a closed volume V with the origin of G located at the
center of mass of the N particles. A local reference frame L1 is
defined for referring N1 (1<N1<N) particles contained within volume V1
(0<V1<V) with the origin of L1 located at the center of mass of these
N1 particles. Thus the local reference frame L1 can be considered as a

subset of global reference frame G. Further, the local reference frame

L1 is defined to be co-moving with the group of N1 particles in the
global reference frame G. >>

AND

<< In electromagnetism the Maxwell's equations can be wrote with
multiple integrals to calculate the total magnetic and electric fields.

In the example the electric field produced by a distribution of charges

is obtained by a triple integral of a vector function:>>
http://en.wikipedia.org/wiki/Multiple_integral

Are you saying, in another form that the near-field of Maxwell's
is the only place SR has any validity?

The theory has a disclaimer that most of the H.G Wells fans
prefer to ignore:
<< In order to give due prominence to this relationship, however,
we must replace the usual time co-ordinate t by an imaginary
magnitude [sqrt -1] >>
http://www.bartleby.com/173/17.html

I agree it is a bit of sneaky pool to analyze in imaginary space
a postulate formed in Euclidean space. But as at theory
of invariances it has its utility.

You might review your arguments in light of the above
disclaimer to be sure you are arguing against the theory
and not the interpretations of others.

I have no interest in legalistic word parsing so prefer to
simply label SR as confusing as misleading and rely
on more formal expressions.

IWO... it is an informal theory so the sky won't fall with
a formal disproof. :o)

Nah, it's more fun here.

tau = t*sqrt(1-v²/c²)
tau = t*sqrt(1-u²/c²)
tau = t*sqrt(1-w²/c²)
xi = (x-vt)/sqrt(1-v²/c²)
eta = (y-ut)/sqrt(1-u²/c²)
zeta= (z-wt)/sqrt(1-w²/c²)

Einstein said
"eta = y,
zeta = z "
and "Only two things are infinite, the universe and human stupidity, and I'm
not sure about the former." --Albert Einstein

You should have this work professionally critiqued first. As is, you've
wasted a lot of time for nothing. The text is very sloppily written and
very hard to read because of that. There is no math or physics, mostly
English prose. Your main reference appears to be Einstein's
popularisations of his work, not Einstein's work itself. And so on and
so on.

Bottom line is the usual one: there is no silly error in relativity
since its mathematical structure is that of a certain type of geometry
on linear space which is known to be as self-consistent as Euclidean
geometry. So if your paper was correct, you would invalidate standard
high-school Euclidean geometry as well. Good luck on that one.

This is not to say scientists actually believe relativity is somehow
sacrosanct. Nothing in physics is. It's simply a proven set of
conclusions given certain assumptions. These assumptions can in
principle be contradicted by experiment (that's one reason relativity
is science, not religion) just like anything else in physics.

Invalidity of SR
http://www.geocities.com/gurcharn_sandhu/funda1/reference_art5.htm

I have studied the special theory of relativity in depth and over a
long period of time. There is nothing wrong in the mathematical
structure of this theory. However I find both postulates of SR to be
fundamentally wrong. Out of these two postulates, I have discussed the
Principle of Relativity at length and logically shown its invalidity.
The second postulate was evolved out of the 'principle of constancy of
velocity of light in vacuo (vacuum), essentially to reconcile it with
the Principle of Relativity. Hence to discuss the invalidity of SR, we
only need to discuss the invalidity of the Principle of Relativity. Of
course the dynamic relations of SR have been shown to be resulting from
the inertial property of all forms of energy and will remain valid even
after the collapse of SR.

Invalidity of the Principle of Relativity

I have developed the main arguments to show the invalidity of the
relativity principle through three introductory articles.

1. Inertial Reference Frames and the ICRS
http://www.geocities.com/gurcharn_sandhu/funda1/reference_art2.htm

Here I have compared the fundamental notion of 'Inertial Reference
Frames in relative motion' with the International Celestial Reference
Frame and highlighted the inadequacy of this notion.

2. Validity of Assumptions and Postulates
http://www.geocities.com/gurcharn_sandhu/funda1/reference_art3.htm

Here I have primarily highlighted the necessity of critical examination
and logical scrutiny of the basic postulates rather than treating them
as axiomatic basis of a new theory. Specifically I have highlighted the
point that 'any assumption for any analysis of a system of particles
within a closed volume of space must not violate the conservation of
total momentum and total mass-energy content'.

3. Relative Measurements in Local Reference Frames
http://www.geocities.com/gurcharn_sandhu/funda1/reference_art4.htm

Here I have highlighted the necessity of imposing certain physical
constraints on the choice of valid reference coordinate systems and
also shown the inadequacy of purely relative measurements without
reference to a common bigger or global reference frame. e.g.
'Obviously within the closed volume V under consideration, the total
momentum and the total mass-energy content of the given N particles
will be conserved. We may refer this set of N particles to any
coordinate reference frame for quantifying or assigning certain measure
numbers to the relative positions of these particles, but that must not
alter the physical state (e.g. pressure and temperature distribution)
or content of matter (e.g. mass-energy content) within the closed
volume under consideration. This requirement may be treated as a
physical constraint on the choice of valid coordinate reference
frames.'

You are now requested to bring out any specific point, which appears to
be not convincing enough, for detailed discussion.

I will try to make it not convincing, the web site sucks,
can't you afford a real ISP with a real hosting service?

SR was considered to be invalid by Einstein in the
presence of gravity without certain restrictions, else he
would have never devised General Relativity.

But chances are, he never considered your points,
and chances are you never considered his.

The thing that seems odd to me is that the crackpots
and nuts seem to have more scientific curiosity than the
scientists (who post here).

And the most useless thing thing in the world is
somebody who is egotistical enough to think they know
more about relativistic physics than anyone else.

Is that not convincing enough?

Now I need to run my adware remover to make
sure a geocities ad is not still on the computer, just
to not convince myself that not all web hosters are

Well if you cannot bring out any specific point for discussion, why not
give me your response on just one point which I had highlighted in my
previous post. That is -

Here I have highlighted the necessity of imposing certain physical
constraints on the choice of valid reference coordinate systems and

This is incorrect. Consider a closed volume V with a single electron in
it. A proton sits in the region outside the closed volume V. The
mass-energy content of the electron inside the closed volume V will not
be conserved.

Perhaps you need to redefine what you mean by a "system".

That is also incorrect. The *value* of the mass-energy content of a

Since the electron and proton considered by you are continuously
interacting the volume V enclosing a single electron cannot be
considered a closed volume.

We mean a system of mutually interacting particles which constitute a
group such that the whole group of particles can be considered as
co-moving with their center of mass.

Conservation of mass-energy content within a closed volume of space is
the most fundamental conservation principle. The mass-energy content
can be transfered from one region to another region through some
physical process or interaction but its total content cannot be
arbitrarily increased or decreased.

I see that you are reconsidering what you mean by a system. Now I have
the following questions:
1. Considering that there are at least two interactions
(electromagnetic and gravitational) that have infinite range, how are
you going to define a finite, closed volume that does not interact with
any other objects outside the system?
2. Is it important that there be no interaction at all with objects
outside the volume or only no *net* interaction at all with objects
outside the volume?
Post by GSS
We mean a system of mutually interacting particles which constitute a
group such that the whole group of particles can be considered as
co-moving with their center of mass.
Since the center of mass is *defined* as the weighted average of the
masses of the particles in the system, then yes I suppose the center of
mass must move with the group. Note that this does *not* mean that the
particles have the same direction or magnitude of motion as the center
of mass. Consider two billiard balls moving in opposite directions at
the same speed and their center of mass which is motionless. Or
consider two billiard balls moving in opposite directions at different
speeds, so that the center of mass is moving in the same direction as
one of the balls but not the other.

system is *not* held to be invariant with the choice of coordinate
reference frames. I don't know why you think it would be.
Conservation of mass-energy content within a closed volume of space is
the most fundamental conservation principle. The mass-energy content
can be transfered from one region to another region through some
physical process or interaction but its total content cannot be
arbitrarily increased or decreased.
This conservation principle applies within a single but arbitrarily
chosen inertial frame. It also applies within any other choice of that
inertial frame. That is, what it means is that the total mass-energy
content of the system will be invariant regardless of how the particles
in the system interact. However this does *not* mean that the value of
the mass-energy content is independent of the choice of inertial frame.

Consider a single billiard ball. In a particular reference frame it
will have a velocity of 20 m/s and will have an appropriate amount of
mass-energy. In another reference frame, the *same* ball at the *same*
instant will have a velocity of zero and will have a different amount
of mass-energy. Note this is *classical* mechanics here -- we're not
invoking special relativity at all.

tau = (t-vy/c²)/sqrt(1-u²/c²)
tau = (t-wx/c²)/sqrt(1-w²/c²)
xi = (x-vt)/sqrt(1-v²/c²)
eta = (y-ut)/sqrt(1-u²/c²)
zeta= (z-wt)/sqrt(1-w²/c²)
which is exactly the same?

Fucking incompetent morons.

Phuckwit Duck, go back to answering the questions posed to you in other
threads
instead of fleeing and spiking another thread.
You already know this, but I very rarely answer any questions from
Androcles, not only because of his extremely poor manners, but because
he is so firmly committed to his stupidity.

Dear Phuckwit Duck,
As an extremely devoted relativist, would you be so kind as to
explain why the idiot Einstein said
eta = y,
zeta = z?
Did he not know how to move sideways or up?
tau = t*sqrt(1-v²/c²)
tau = t*sqrt(1-u²/c²)
tau = t*sqrt(1-w²/c²)
xi = (x-vt)/sqrt(1-v²/c²)
eta = (y-ut)/sqrt(1-u²/c²)
zeta= (z-wt)/sqrt(1-w²/c²)
I know it is extremely stupid to believe
tau = t*sqrt(1-w²/c²)
zeta= (z-wt)/sqrt(1-w²/c²)
but I also know how committed you are to spreading your stupid
views.
Do you not know how to move sideways or up, Phuckwit Duck?
Androcles.
Please, you know better than this. It is a matter of choosing a convenient
coordinate system. Surely you do not believe that the choice of coordinate
system influences the actual physics at work?
Look up "Standard configuration". It is quite simple.
/ Jesper P
And do try at least to get the Lorentz transformations right the next time
you copy+paste this.
One can attempt something along the lines of the following:

Let O, A, B, and C be four observers, moving in the following
rather peculiar fashion. A is moving +v_A with respect to O
in the positive X direction. B is moving +v_B with respect to *A*
in the positive Y direction. C is moving +v_C with respect to B
in the positive Z direction. All four observers are coincident
at time 0 (as measured by each clock).

How do O and C relate, coordinate-system wise?

According to the standard Lorentz, where I've set c=1,
g_A = 1/sqrt(1-v_A^2), g_B = 1/sqrt(1-v_B^2),
g_C = 1/sqrt(1-v_C^2) for convenience:

x_A = (x_O - v_A * t_O) * g_A
y_A = y_O
z_A = z_O
t_A = (t_O - v_A * x_O) * g_A

x_B = x_A
y_B = (y_A - v_B * t_A) * g_B
z_B = z_A
t_B = (t_A - v_B * y_A) * g_B

x_C = x_B
y_C = y_B
z_C = (z_B - v_C * t_B) * g_C
t_C = (t_B - v_C * z_B) * g_C


Ergo,

x_C = (x_O - v_A * t_O) * g_A
y_C = x_O * v_A * v_B * g_A * g_B + y_O * g_B - v_B * g_A * g_B * t_O
z_C = x_O * v_A * v_C * g_A * g_B * g_C
+ y_0 * v_B * v_C * g_B * g_C
+ z_0 * g_C - v_C * g_A * g_B * g_C * t_O
t_C = t_O * g_A * g_B * g_C - v_A * g_A * g_B * g_C * x_0
- v_B * g_B * g_C * y_0 - v_C * g_C * z_0

So from a mathematical standpoint, the theory doesn't work all that
well, though neither does the actual problem setup. Of course
having tau equated to three different values verges on the silly.

The best I can do at this point is redo the problem using an
arbitrary vector, attempting to project said vector onto the
coordinate axes. I'd have to rotate the coordinate system,
do the Lorentz, and rotate it back, though. (Yuck.)

And when all is said and done, what really happened? Nothing.
It's a mathematical game, at best, here, though SR has
been generally confirmed using more straightforward methods.

Why bother setting up three equations? Since any combination
of lorentz transsforms is also a lorentz transform, just add up
all the velocities.

u = (v_1 + v_2 + v_3)

k^2 = (1/2)[u^2 - (v_1)^2 - (v_2)^2 - (v^3)]

The total boost is:

v' = (u + v_3(v_1.v_2))/(1 + k^2)


Never work hard unless being lazy fails.

I did not assume that the velocities were all along one axis. I
assumed something more general than that. (Note the ``dot'' product
in the equation below. Pick the directions however you like. I
simplified the other scalar products to get the sums of the squares
of the velocities with themselves, hence the somewhat odd looking
term defined as k^2:

u = (v_1 + v_2 + v_3)

u^2 = (v_1 + v_2 + v_3) . (v_1 + v_2 + v_3)

= (v_1)^2 + (v_2)^2 + (v^3) + 2 (v_1 . v_2 + v_1 . v_3 + v_2 . v_3)

And since the second term on the rhs appeared in the denominator, I
rewrote it as the term defined as k^2.

However, I can sympathize with his choice. Like many classical physics
problems, the choice of orientation of reference frame is arbitrary and
is chosen for simplicity. For example, good-old-blocks-and-planes
problems can be analyzed with one of the axes being horizontal or with
one of the axes being parallel to the inclined plane, without loss of
generality. I'm therefore grateful that Einstein chose a reference
frame system that made the analysis simpler. The Lorentz transformation
in an arbitary direction is shown in most textbooks that dive into the
topic with anything more than cursory attention. Sadly, it doesn't have
much resemblance to what you wrote above, which is wrong.

I see that you are reconsidering what you mean by a system.
1. Considering that there are at least two interactions
(electromagnetic and gravitational) that have infinite range, how are
you going to define a finite, closed volume that does not interact with
any other objects outside the system?
2. Is it important that there be no interaction at all with objects
outside the volume or only no *net* interaction at all with objects
outside the volume?
A finite closed volume V is defined for the present analysis to be such
that during the period of time under consideration, there is no net
gain or loss of total mass-energy content within the closed volume.
That is to say there is no net transfer of mass-energy content across
the boundary surface of the closed volume V.
Post by PD
Post by GSS
We mean a system of mutually interacting particles which constitute
a group such that the whole group of particles can be considered as
co-moving with their center of mass.
Since the center of mass is *defined* as the weighted average of the
masses of the particles in the system, then yes I suppose the center of mass must
move with the group. Note that this does *not* mean that the particles have the same
direction or magnitude of motion as the center of mass. Consider two billiard balls
moving in opposite directions at the same speed and their center of mass which is
motionless. Or consider two billiard balls moving in opposite directions at different
speeds, so that the center of mass is moving in the same direction as one of the
balls but not the other.
Yes, the main feature of the center of mass reference coordinate frame
is that the total momentum of all particles in it is zero.
Post by PD
Post by GSS
Conservation of mass-energy content within a closed volume of space
is the most fundamental conservation principle. The mass-energy
content can be transfered from one region to another region through
some physical process or interaction but its total content cannot be
arbitrarily increased or decreased.
This conservation principle applies within a single but arbitrarily
chosen inertial frame. It also applies within any other choice of that
inertial frame. That is, what it means is that the total mass-energy
content of the system will be invariant regardless of how the particles
in the system interact. However this does *not* mean that the value of
the mass-energy content is independent of the choice of inertial frame.
Yes, this is the most crucial point and needs to be elaborated.

Let us consider a large group of mutually interacting particles
enclosed within an infinitely large closed volume V, say enclosing our
solar system or say enclosing our galaxy, or say enclosing our
universe. Let us assume that we do not use any reference coordinate
frame to quantify the relative positions of these particles. In spite
of the fact that there is no reference coordinate frame, there will be
certain finite number of matter particles, certain finite distribution
of pressure and temperature, certain finite field energy distribution
and certain finite distribution of radiation energy within this closed
volume. In short the total mass-energy content within this closed
volume V exists independent of the fact whether we have chosen any
reference coordinate frame or not. This fact is as simple and as
straight forward as another simple fact that you as a human being
possess certain finite mass-energy content even if you are not referred
to any reference coordinate frame. Now the principle of conservation of
total mass-energy content within a closed volume V will require that
when we introduce an appropriate reference coordinate frame to quantify
the relative positions of all particles, it should not alter the total
mass-energy content within V.

Let us for a moment digress from this point. In tensor analysis there
is a notion of admissible coordinate transformations that ensure the
invariance of the line element ds and hence the invariance of space
points in general. On similar lines we can have the notion of
admissible choice of reference coordinate frames that will ensure the
conservation of total mass-energy content within a closed volume V.
Such an admissible choice consists of a reference coordinate frame with
its origin either located at the center of mass of all particles
contained within V or is at rest with respect to that center of mass.
Such an admissible reference coordinate frame can be considered as a
preferred reference frame for that closed volume V. If we consider the
closed volume V to enclose the entire universe than this preferred
reference frame will be known as the Universal or Absolute Reference
Frame. If we consider the closed volume V to enclose the entire solar
system than this preferred reference frame will be the one with its
origin either located at the barycenter of the solar system or at rest
with respect to the barycenter. Barycentric Celestial Reference Frame
is such a preferred reference frame for our solar system. Hence the
total mass-energy content of the solar system will be conserved in all
such reference coordinate frames which are at rest with respect to the
BCRF. In general for any closed volume V, all non-rotating reference
coordinate frames that are at rest with respect to the center of mass
of all particles contained in V, can be termed as global or preferred
or admissible frames for that closed volume.

Consider a single billiard ball. In a particular reference frame it
will have a velocity of 20 m/s and will have an appropriate amount of
mass-energy. In another reference frame, the *same* ball at the *same*
instant will have a velocity of zero and will have a different amount
of mass-energy. Note this is *classical* mechanics here -- we're not
invoking special relativity at all.
PD
If the particular reference frame under consideration is the global or
preferred reference frame for the region of space contained within a
closed volume V then the observed velocity can be considered as true
velocity and the total mass-energy content will be conserved within the
closed volume V. If on the other hand the particular reference frame
under consideration is only a local reference frame then the observed
velocity will be the relative or apparent velocity and not the true
velocity.
Mass-energy content computed from such apparent velocity will only be
an apparent mass-energy content. For example the angular velocity w of
a particular star traversing the sky may be taken as 2.pi radians per
day. If R is the distance of that star from the earth then 2.pi.R can
be taken as the instantaneous apparent or relative velocity of that
star moving in the sky. We cannot use this apparent velocity for
computing the true mass-energy content of that star.
Therefore if we wish to be extremely precise and accurate we must refer
all motion of particles or groups of particles with in a closed volume
of space to the preferred or global reference coordinate system for
that closed volume. Within the solar system BCRF is the preferred or
global reference frame.
In *classical* mechanics we do not enunciate new special theories based
on relative or apparent velocities of particles.

I see that you are reconsidering what you mean by a system.
1. Considering that there are at least two interactions
(electromagnetic and gravitational) that have infinite range, how are
you going to define a finite, closed volume that does not interact with
any other objects outside the system?
2. Is it important that there be no interaction at all with objects
outside the volume or only no *net* interaction at all with objects
outside the volume?
A finite closed volume V is defined for the present analysis to be such
that during the period of time under consideration, there is no net
gain or loss of total mass-energy content within the closed volume.
That is to say there is no net transfer of mass-energy content across
the boundary surface of the closed volume V.

We mean a system of mutually interacting particles which constitute
a group such that the whole group of particles can be considered as
co-moving with their center of mass.
Since the center of mass is *defined* as the weighted average of the
masses of the particles in the system, then yes I suppose the center of mass must
move with the group. Note that this does *not* mean that the particles have the same
direction or magnitude of motion as the center of mass. Consider two billiard balls
moving in opposite directions at the same speed and their center of mass which is
motionless. Or consider two billiard balls moving in opposite directions at different
speeds, so that the center of mass is moving in the same direction as one of the
balls but not the other.
Yes, the main feature of the center of mass reference coordinate frame
is that the total momentum of all particles in it is zero.

Conservation of mass-energy content within a closed volume of space
is the most fundamental conservation principle. The mass-energy
content can be transfered from one region to another region through
some physical process or interaction but its total content cannot be
arbitrarily increased or decreased.
This conservation principle applies within a single but arbitrarily
chosen inertial frame. It also applies within any other choice of that
inertial frame. That is, what it means is that the total mass-energy
content of the system will be invariant regardless of how the particles
in the system interact. However this does *not* mean that the value of
the mass-energy content is independent of the choice of inertial frame.
Yes, this is the most crucial point and needs to be elaborated.
Let us consider a large group of mutually interacting particles
enclosed within an infinitely large closed volume V, say enclosing our
solar system or say enclosing our galaxy, or say enclosing our
universe. Let us assume that we do not use any reference coordinate
frame to quantify the relative positions of these particles. In spite
of the fact that there is no reference coordinate frame, there will be
certain finite number of matter particles, certain finite distribution
of pressure and temperature, certain finite field energy distribution
and certain finite distribution of radiation energy within this closed
volume. In short the total mass-energy content within this closed
volume V exists independent of the fact whether we have chosen any
reference coordinate frame or not. This fact is as simple and as
straight forward as another simple fact that you as a human being
possess certain finite mass-energy content even if you are not referred
to any reference coordinate frame. Now the principle of conservation of
total mass-energy content within a closed volume V will require that
when we introduce an appropriate reference coordinate frame to quantify
the relative positions of all particles, it should not alter the total
mass-energy content within V.
Let us for a moment digress from this point. In tensor analysis there

invariance of the line element ds and hence the invariance of space

Such an admissible choice consists of a reference coordinate frame with
its origin either located at the center of mass of all particles

Such an admissible reference coordinate frame can be considered as a
preferred reference frame for that closed volume V. If we consider the

closed volume V. If on the other hand the particular reference frame

velocity.
Mass-energy content computed from such apparent velocity will only be
an apparent mass-energy content. For example the angular velocity w of
a particular star traversing the sky may be taken as 2.pi radians per
day. If R is the distance of that star from the earth then 2.pi.R can
be taken as the instantaneous apparent or relative velocity of that

of space to the preferred or global reference coordinate system for
that closed volume. Within the solar system BCRF is the preferred or
global reference frame.
In *classical* mechanics we do not enunciate new special theories based
on relative or apparent velocities of particles.
And now your arguments and definitions have gotten a little circular:
1. Mass-energy is conserved inside a closed volume, which is defined to
be a volume such that mass-energy is conserved.
2. Mass-energy has the same numerical value for all reference frames,
but only the mass-energy that is measured in the global reference frame
is the true value, and other mass-energy measurements in other
reference frames are only apparent values and not true values.

Thanks, I've learned all I need to about your model.

I have studied the special theory of relativity in depth and over a

structure of this theory.
Of course there is something wrong.
This is what is wrong:
[quote]
we establish by definition that the "time" required by a turtle to travel
from A to B equals the "time" it requires to travel from B to A.
[end quote]
Ref: http://www.fourmilab.ch/etexts/einstein/specrel/www/

Einstein can prove nothing can go faster than a turtle.

Oops!... Did I say 'a turtle'? Sorry...'light'.

"In agreement with experience we further assume the quantity
2AB/(t'A-tA) = c,
to be a universal constant--the velocity of light in empty space." --
Einstein.

In agreement with experience and without any assumption at all,
x = AB
-x = BA,
x + (-x) = 0.
Hence (AB+BA)/(t'A-tA) = 0.
Post by GSS
However I find both postulates of SR to be
fundamentally wrong.
Halfwit! Only one is wrong, the stupidity of light velocity being
independent of its source.
Post by GSS
Out of these two postulates, I have discussed the
Principle of Relativity at length and logically shown its invalidity.
You don't even know that the PoR is or what logic is, you halfwit.
(Notice I'm calling you a halfwit and not a dimwit, nitwit or phuckwit...)

"Take, for example, the reciprocal electrodynamic action of a magnet and a
conductor. The observable phenomenon here depends only on the relative
motion of the conductor and the magnet.
Examples of this sort--- yada yada yada--- will hereafter be called the
"Principle of Relativity'' ---"

If you don't think the conductor meets the magnet when the magnet meets the

I have studied the special theory of relativity in depth and over a

Again, I recommend a series of face to face discussions with a pro. It
might not be easy to find a willing expert but it will save you years
of wasted time. (Self-delusion doesn't matter as long as you find it
entertaining and rewarding.)

One thing that became obvious to me after being on this bboard since
its inception is that this type of environment is singularly unsuited
for real scientific debate (few exceptions do exist). Exchanges that in
direct personal communication take 30 minutes, on a board like this
stretch to literally *years* during which nobody remembers anymore what
it is they are arguing about.

Yes, I had a look at these. These articles are quite well written.
I am fully aware of the prevailing environment. Kindly go through my
first article on the state of Fundamental Research in Physics at
http://www.geocities.com/gurcharn_sandhu/funda1/funda_article.htm

Not only we must have an open mind, we must be able to judge and
evaluate new suggestions and ideas on logical grounds. We cannot afford
to shut our eyes and mind to any new suggestion or viewpoint.

I therefore request you to kindly confirm if you have understood my
viewpoint. If not kindly go through the following and then we shall
discuss the specific points of our disagreement if any.

Invalidity of SR
http://www.geocities.com/gurcharn_sandhu/funda1/reference_art5.htm

I have studied the special theory of relativity in depth and over a
long period of time. There is nothing wrong in the mathematical
structure of this theory. However I find both postulates of SR to be
fundamentally wrong. Out of these two postulates, I have discussed the
Principle of Relativity at length and logically shown its invalidity.
The second postulate was evolved out of the 'principle of constancy of
velocity of light in vacuo (vacuum), essentially to reconcile it with
the Principle of Relativity. Hence to discuss the invalidity of SR, we
only need to discuss the invalidity of the Principle of Relativity. Of
course the dynamic relations of SR have been shown to be resulting from
the inertial property of all forms of energy and will remain valid even
after the collapse of SR.

Invalidity of the Principle of Relativity

I have developed the main arguments to show the invalidity of the
relativity principle through three introductory articles.

1. Inertial Reference Frames and the ICRS
http://www.geocities.com/gurcharn_sandhu/funda1/reference_art2.htm

Here I have compared the fundamental notion of 'Inertial Reference
Frames in relative motion' with the International Celestial Reference
Frame and highlighted the inadequacy of this notion.

2. Validity of Assumptions and Postulates
http://www.geocities.com/gurcharn_sandhu/funda1/reference_art3.htm

Here I have primarily highlighted the necessity of critical examination
and logical scrutiny of the basic postulates rather than treating them
as axiomatic basis of a new theory. Specifically I have highlighted the
point that 'any assumption for any analysis of a system of particles
within a closed volume of space must not violate the conservation of
total momentum and total mass-energy content'.

3. Relative Measurements in Local Reference Frames
http://www.geocities.com/gurcharn_sandhu/funda1/reference_art4.htm

Here I have highlighted the necessity of imposing certain physical
constraints on the choice of valid reference coordinate systems and
also shown the inadequacy of purely relative measurements without
reference to a common bigger or global reference frame. e.g.
'Obviously within the closed volume V under consideration, the total
momentum and the total mass-energy content of the given N particles
will be conserved. We may refer this set of N particles to any
coordinate reference frame for quantifying or assigning certain measure
numbers to the relative positions of these particles, but that must not
alter the physical state (e.g. pressure and temperature distribution)
or content of matter (e.g. mass-energy content) within the closed
volume under consideration. This requirement may be treated as a
physical constraint on the choice of valid coordinate reference
frames.'

You are now requested to bring out any specific point, which appears to
be not convincing enough, for detailed discussion.

Physics forums are where kooks, cranks, and trolls go for their

Science is *built* on trying to tear down current theory, as

If you find that your tiny little feelings are hurt when someone

Special Relativity is defined for situations where gravity is
negligible. You struggle over postulates that *require* no
gravity, that is why it is called "special". You have not shown
anything "invalid", except your understanding of relativity.

Dear David,
Thanks for your critical response.
Let me respond to your observations.

<QUOTE>
We appear to have been steadily indoctrinated into believing that due
to complexity of physical reality, we can not even demand deeper
meaning, deeper understanding and mental visualization of the basic
phenomena in quantum mechanical world.
<END QUOTE>
Nature provides the illusion of a continuous world, for our "common sense" to be
trained in.
This statement is a plain assumption which is elevated to the state of
a doctrine because of the general indoctrination I referred to. Why
don't we simply admit that our understanding of the Nature as yet is
too imperfect?
Concentrating on the fundmental "deeper reality" that the quantum realm represents, >strips away "indoctrination" and "complexity". Writing a web page such as you have >done doesn't make it clearer for anyone. EinsteinHoax does that too.
Wrong. The indoctrination is an induced mental state which cannot be
stripped away by quantum realm.
I do not know the writer of EinsteinHoax. I read his article about
three years back and was quite impressed by it. Even though he is a
little too blunt, he represents millions of those scientists and
engineers who are intuitively convinced that there is something
seriously wrong with the Relativity Theories but cannot pinpoint
exactly what is wrong.

<QUOTE>
A close scrutiny of scientific discussions in Physics forums during the
past one decade or so shows that our overall thinking or collective
'Human Thought', concerning fundamental Physics issues, is badly

I disagree. Because of the indoctrination in the mainstream, all
dissenting voice is stifled. This in turn has stifled our progress in
fundamental physics.

<QUOTE>
Although a divided opinion during the evolution of a new thought may be
regarded as a normal phenomenon, yet a divided opinion lingering on for

I agree. Let us therefore cooperate in tearing down the ill founded
Relativity Theories.
However I find both postulates of SR to be fundamentally wrong.
Only the first postulate is required. "The laws of physics are the same for all inertial >systems". From that postulate, Maxwell's relations provide the same value for c for all >inertial observers. The second postulate is redundant.
Wrong. Maxwell's relations provide the same value for c only for the
vacuo or vacuum. Essentially to reconcile the notions of the principle
of relativity with the requirement of the constancy of the velocity of
light in vacuum, the second postulate had to be introduced. Under the
second postulate the requirement of constancy of velocity of light in
vacuum was changed over to the requirement of constancy of the velocity
of light in each of the infinitely many inertial reference frames by
sacrificing the absolute nature of space and time coordinates.
Out of these two postulates, I have discussed the Principle of Relativity at length and >>logically shown its invalidity.
You have made the most fundamental of mistakes. You define a "Barycentric
Celestial Reference System", and you talk about "center of mass of the Solar System" >and "planetary motion"
Dear Sir, I have not defined "Barycentric Celestial Reference System",
it is the International Earth Rotation and Reference Systems Service
(IERS) who have defined it. Kindly look at the following links,
http://www.iers.org/iers/about/tor/
http://www.iers.org/iers/publications/tn/tn29/tn29_031.pdf
http://www.iers.org/iers/earth/icrs/icrs.html
I talk about the "center of mass of the Solar System" because by its
very definition the Barycenter is the center of mass of the solar
system.

Regarding the mention of "planetary motion" let me quote from an
article on "Comparison of "Old" and "New"
Concepts: Reference Systems" by Jean Kovalevsky in IERS Technical Note
No. 29.
"5 Further Remarks
1. The motion of the barycenter of the solar system is not linear in
its orbit about the center of the Galaxy. There is therefore a
Coriolis-like acceleration, which gives rise to a galactic geodesic
precession. It is not included in the definition of the ICRS. This
means that one should either distinguish between a natural barycentric
system from the BCRS, or to apply, in the dynamical representations of
the motion of planets in the BCRS, the corresponding acceleration. "

I had referred to these remarks just to show that even BCRS is not a
truly inertial reference frame.
What is it about "in the absence of mass" that you did not
understand?

I sincerely hope that you understand the basic fact that "in the
absence of mass" there is no barycenter, no solar system, no galaxy and
no universe.
Special Relativity is defined for situations where gravity is negligible. You struggle
over postulates that *require* no gravity, that is why it is called "special".
Kindly make it clear that as per your understanding whether the SR is
defined within our Solar system.
Kindly also make it clear that as per your understanding where exactly
the two postulates of SR that *require* no gravity are valid. Are they
valid anywhere in our universe?

However, let me clarify that in all my arguments justifying the
invalidity of SR, I have not used the term 'gravity' or 'gravitation'
anywhere. Just for illustration, consider the following argument which
does not depend upon the existence or otherwise of gravity.

'Let us consider a closed volume V of space containing a system of N
particles of matter in all possible physical states. We consider the
closed volume of space in the sense that there is no transfer of mass
or energy across the boundary surface of this volume and the enclosed
particles do not experience any significant force or interaction from
outside this volume. Let point S be the center of mass of these N
particles and let G be a non-rotating Cartesian coordinate reference
frame with its origin located at point S. In this reference frame G,
let the positions of all N particles be defined to be certain function
of time (x^i(t), y^i(t), z^i(t)), provided they remain bounded within
the closed volume V. Since G is a reference frame with origin at the
center of mass of the enclosed N particles, total momentum of all of
its domain particles is zero.

Obviously within the closed volume V under consideration, the total
momentum and the total mass-energy content of the given N particles
will be conserved. We may refer this set of N particles to any
coordinate reference frame for quantifying or assigning certain measure
numbers to the relative positions of these particles, but that must not
alter the physical state (e.g. pressure and temperature distribution)
or content of matter (e.g. mass-energy content) within the closed
volume under consideration. This requirement may be treated as a
physical constraint on the choice of valid coordinate reference
frames.'

With this it is impossible to consider all inertial reference frames in
relative uniform motion to be equivalent.
Once a particular inertial reference frame say L1, is defined to be in
relative uniform motion with respect to the given reference frame say
BCRF, their equivalence becomes invalid on the grounds of
non-conservation of total momentum and total mass-energy content of the
solar system.

Further I have shown the inadequacy of purely relative measurements
which are in no way dependent on the existence or otherwise of gravity.
You have not shown anything "invalid", except your understanding of relativity.
... <rest snipped, unread>

This is a clear sign of indoctrination.
How can you see the invalidity of SR if you snip the argument as
unread!!
You are now requested to bring out any specific point,
which appears to be not convincing enough, for
detailed discussion.
Done.
David A. Smith

Let me see if I understand this correctly. In the last half century,
physics has made more progress than in the histpry of science prior to
that time. Withing the last century, physicists have discovered two
forces not not known to exist before the turn of the 20th century,
and in that time, explained them and unified with them electromagnetism.
The physical theories we have now are the most precise theories ever
created in the history science. All of those theories are based on
relativity and quantum field theory.

Perhaps your expectations were a bit high, given the incredible
successes of the theories developed through the 20th century. But,
if not, precisely what is being stifled and precisely which dissenting
voice is going chirp up and establish some credibility with a calculation
for simple, well known, physical result before demanding a reasearh
program to solve the hard stuff?

Don't be naive. I can derive special relativity from the first

on this newsgroup, so I know it can be done no matter how many tme
you say that it can't. I can also derive maxwell's equations

Sure. Special relativity is valid anywhere that gravitational fields
are of no interest, which just about everywhere for any purpose other
than studying the behaviour of large objects on a cosmological scale.
Most physicists find it useful to gauge their choice of approximations
by the physical content of what is being calculated. Not only does
that indicate a grasp of the physics but it saves a great deal of
unnecessary labor. But that is just a personal preference for thinking
before throwing math at anything.

the two postulates of SR that *require* no gravity are valid. Are they

Let me see if I can summarize this concisely. Are you interested
in gravitational effects? [Yes/No] If Yes, then you need to use
general relativity. If No, then you can still use general relativity
if you aren't deterred by the thought of making something as hard as
possible for no particular reason. On the other hand, if you have
better things to do than spend a few extra days doing quality control
for the BIC pen corporation, you can skip general relativty and stick
with special relativity, or even plain old newtonian mechanics if
special relativity is overkill.

Uh, that doesn't follow. In relativity, you must use the center
of momentum. Center of mass is a classical concept. However, you will
be happy to know that center of momentum coordinates are so useful
that accelerator labs throught the world endorse them for the simplicity
they offer.

Obviously within the closed volume V under consideration, the total
momentum and the total mass-energy content of the given N particles

Let me state that precisely: If the p1^u, p2^u, ... pn^u are
four momenta, then, in the center of momentum frame and the total
four mometum is P^u, then since P^u P_u = M^2 is true in _any_
frame,

(p1 + p2 + ... + pn)^u (p1 + p2 + ... + pn)_u = M^2

where M^2 is _not_ the sum of the masses, but sum of the square
of the four momenta. Since that expression is an invariant, you
may pick any frame you wish, including the one in which
the sum of the three momenta is zero. You can also choose a
frame that is as unintuitive as you like or anything inbetween.

This is a clear sign of a kook argument which attempts to substitute

you have decided you simply dislike relativity without knowing anything

Well, for starters, nothing you've posted really resembles the actual
theory of relativity and there are only so many strawman arguments one can
read before deciding the next 100+ lines aren't going to break a trend. If
you had an actual argument, putting it first and placing the strawman
arguments further down would be a better strategy. An even better strategy
would be to not even include the straman arguments, since it tends to give
the impression that you don't understand the subject. That will also make
your posts shorter and more concise.

First, you're going to have to post something that looks like an
argument against relativity and that means relativity as it it is
understood by physicists, not caricatures and strawman arguments collected
from a google search for kooky slogans. If you don't know what a
four-vector is or you continue to insist that light has some relevance to
deriving the lorentz transformations, the best you can expect is that I'll
agree that you have proven your understanding of relativity is wrong.
If you want to be considered an expert, you'll need the expertise expected

The invariance of that expression signifies that *during* particle
interactions total energy and total momentum is *conserved* in all
reference frames. What I am referring to is the total value of
mass-energy content within a closed volume V of space. Let us consider
the closed volume V to enclose the solar system with BCRF as the CoM
reference frame. Let Ms be the total mass-energy content of the solar
system in this frame with zero total momentum. This mass-energy content
as well as the total momentum will be conserved (will be same value) in

all reference frames which are at rest in BCRF but not the same in all
other reference frames that are moving with uniform velocity with
respect to BCRF. Now consider a cosmic particle P approaching the solar
system with relative uniform velocity of 0.9c . Let us mount a
reference coordinate frame L on this particle. The BCRF and L will
constitute a group of inertial reference frames in relative uniform
motion. As observed from the reference frame L, the total energy and
momentum of the solar system will be abnormally high (apparent value).

The SR requires that we should treat both these inertial reference
frames to be equivalent and no one of these can be considered as a
preferred reference frame. The international community of scientists
recognises BCRF as a preferred reference frame for actual use within
our solar system. I don't think we can afford to accept the reference
frame L moving at a uniform relative velocity 0.9c with respect to
BCRF, to be equivalent to BCRF.

Do you agree?

In SR, the center-of-mass frame is essentially useless; it is the
center-of-momentum frame that is useful (c.f. Noether's theorem applied

In GR, neither "frame" is very useful, in general.

I assume you are asking about a closed system (one with no external
interactions).

In SR for a system of pointlike particles, the center-of-momentum frame
satisfies the following condition, where the sum is over all of the
particles:
Sum_i gamma_i m_i v_i = 0
here m_i is the i-th particle's mass, v_i is its 3-velocity (relative to
this coordinate frame), and gamma_i = 1/sqrt(1-v_i^2/c^2). All
quantities are taken simultaneously in this frame. The center-of-mass
frame, on the other hand, satisfies:
Sum_i m_i r_i = 0
where r_i is the 3-vector position of the ith particle (relative to this
coordinate system). Differentiating with respect to the time coordinate
turns the r_i into v_i giving an equation similar to the first, but the
lack of gamma_i implies that these two conditions cannot in general be
satisfied by the same coordinate frame.


This does not depend on the system being either open or closed; nor does
it depend on the type of interaction among the particles, if any -- this
is pure kinematics. Note, however, that if there are external
interactions then these "frames" may not be inertial and energy/momentum
may not be conserved for the set of particles.

It is a most elementary fact that the total momentum in center of mass
coordinate frame is zero.
This is _NOT_ true in SR. Except for a collection of objects of equal mass.
That said, it is true that in casual speech people sometimes mix them up
and call the center of momentum frame "center of mass"; careful people
do not do that.
and for a shut sustem?
I assume you are asking about a closed system (one with no external
interactions).
In SR for a system of pointlike particles, the center-of-momentum frame
satisfies the following condition, where the sum is over all of the
Sum_i gamma_i m_i v_i = 0
here m_i is the i-th particle's mass, v_i is its 3-velocity (relative to
this coordinate frame), and gamma_i = 1/sqrt(1-v_i^2/c^2). All
quantities are taken simultaneously in this frame. The center-of-mass
Sum_i m_i r_i = 0
where r_i is the 3-vector position of the ith particle (relative to this
coordinate system). Differentiating with respect to the time coordinate
turns the r_i into v_i giving an equation similar to the first, but the
lack of gamma_i implies that these two conditions cannot in general be
satisfied by the same coordinate frame.
This is not correct. If relativistic conditions are present, r_1 is in
general not known. If one tries to measure it with a ruler (remember
that according to relativists all the theory deals with is rulers and
clocks) then one needs to account for length contraction, which brings
gamma_i into the picture.

This is obviously another indication, out of very many, that Relativity
carries an internal confict (or inconsistency even) of theory and
measurement.

This does not depend on the system being either open or closed; nor does
it depend on the type of interaction among the particles, if any -- this
is pure kinematics. Note, however, that if there are external
interactions then these "frames" may not be inertial and energy/momentum
may not be conserved for the set of particles.
Crank it up....

Congratulations. You've just proven that either euclidean geometry must
be inconsistent or that you're an idiot. If you found an inconsistency
in hyperbolic geometry, then the same contradiction exists in euclidean
geometry (beltrami, klein, etc.). Take your pick.

The crank strikes again. Relativity is not just a pure formal system.
Relativity makes claims about physical reality. The combination of the
two leads to several inconsistencies. One that comes to mind right away

is the twin paradox.

But you play with words and you think somebody will be impressed by
your misconceptions of what Klein and Beltrami proved or did not prove.

The barucentre should not be nonrelativistic; to presume so means that

With respect to the still sustem, the moving one is open.

if one puts a factor of gamma into the equation for

No measurements at all are required to ascribe a 4-velocity and
4-momentum to an object: its 4-velocity is simply the tangent 4-vector
to its worldline; its mass is "the amount of stuff", and 4-momentum is
simply the product of the two.

I have to wonder whether anyone would still remember the concept today if
the transverse and longitudinal masses weren't explored in the 19th
century in connection to electrodynamics. That set an historical context,
a bit of physics culture, for the special theory to click in to.

Relativistic mass relates to the transverse mass, and is the quantity to
use in quasi-Newtonian treatments of transverse acceleration, like
cyclotron motion. Longitudinal mass is the one to use for accelerations
that increase or decrease energy. So you can't really just plug m_r into
F=ma and run with it.

In relativity, you must use the center of momentum. Center of mass
is a classical concept.
Center of mass coordinate reference frame is also known as center of
momentum reference frame since the total momentum is zero in it.
Pardon me. For some reason, I had the distinct impression you
were talkining about relativity (as one might guess from the
word ``relativity'' in my reply).

Even the spatial component of the 'total four momenta' is also zero in

attempt to use it for newtonian physics.

Obviously within the closed volume V under consideration, the total

Let me state that precisely: If the p1^u, p2^u, ... pn^u are
four momenta, then, in the center of momentum frame and the total
four mometum is P^u, then since P^u P_u = M^2 is true in _any_
frame,
(p1 + p2 + ... + pn)^u (p1 + p2 + ... + pn)_u = M^2
where M^2 is _not_ the sum of the masses, but sum of the square
of the four momenta. Since that expression is an invariant, you
may pick any frame you wish, including the one in which
the sum of the three momenta is zero. You can also choose a
frame that is as unintuitive as you like or anything inbetween.

We may refer this set of N particles to any
coordinate reference frame for quantifying or assigning certain measure
numbers to the relative positions of these particles, but that must not
alter the physical state (e.g. pressure and temperature distribution)
or content of matter (e.g. mass-energy content) within the closed
volume under consideration. This requirement may be treated as a
physical constraint on the choice of valid coordinate reference
frames.'
OK, see above expression for an invariant expression.
The invariance of that expression signifies that *during* particle
interactions total energy and total momentum is *conserved* in all
reference frames.
That expression is only significant in relativity, and since
you are discussing center of mass coordinates, we can't be discussing
relativity.

all reference frames which are at rest in BCRF but not the same in all
other reference frames that are moving with uniform velocity with
respect to BCRF. Now consider a cosmic particle P approaching the solar
system with relative uniform velocity of 0.9c . Let us mount a
reference coordinate frame L on this particle. The BCRF and L will
constitute a group of inertial reference frames in relative uniform
motion. As observed from the reference frame L, the total energy and
momentum of the solar system will be abnormally high (apparent value).
The SR requires that we should treat both these inertial reference
frames to be equivalent and no one of these can be considered as a
preferred reference frame. The international community of scientists
recognises BCRF as a preferred reference frame for actual use within
our solar system. I don't think we can afford to accept the reference
frame L moving at a uniform relative velocity 0.9c with respect to
BCRF, to be equivalent to BCRF.
Do you agree?
No. I tend to think relativity is correct since it predicts the
correct results. In addition, relativity has the advantage of
being conceptually simple and physically intuitive.

It is a most elementary fact that the total momentum in center of mass
coordinate frame is zero.
Try a textbook with facts that are aimed at less elementary readers.
As Tom Roberts has already pointed out, in CoM reference frame by the
very definition of center of mass,
Sum_i[m_i.r_i]=0
where m_i is the (rest) mass of i th particle and r_i is the position
vector of that particle. Differentiating the above relation with
respect to time we get,
Sum_i[m_i.v_i]=Total momentum =0
Post by Bilge

Center of mass coordinate reference frame is also known as center of
momentum reference frame since the total momentum is zero in it.
Pardon me. For some reason, I had the distinct impression you
were talkining about relativity
As Tom Roberts has already pointed out, in situations where particle
velocities are extremely high such that particle mass can no longer be
treated as constant, then we have to use dynamic mass in place of rest
mass. Accordingly gama factor is included in the above relations and
that distinguishes the center of momentum frame from the center of mass
frame. But such cases of extreme velocities are encountered only in
particle accelerators and not in the general case of a large closed
volume under discussion.

Even the spatial component of the 'total four momenta' is also zero in
the CoM frame.
The ``four-momentumm'' is a relativistic quantity, so you shouldn't
attempt to use it for newtonian physics.
This was just to clear your concepts.

That is not momentum in SR.

That is normally called "relativistic mass". It doesn't work -- if one
claims that "center-of-mass" refers to the center-of-"relativistic"-mass
frame, then one must include the gamma inside the time derivative, and
again that frame is in general different from the center-of-momentum frame.

BTW nobody who knows much about modern physics would do that (because
"relativistic mass" is a bastard quantity, neither scalar nor vector,
and it is not _intrinsic_ to the object)....

"Equivalent" is not "the same". The _LAWS_OF_PHYSICS_ are the same in
the two frames, and that is what is meant by their equivalence. The fact
that the components of the solar system have very different velocities
relative to these two frames is simply one aspect of their not being
"the same".

Firstly the mass-energy content of all material bodies, like aircraft,

Secondly if we compute the dynamic trajectories of all such bodies
with distorted mass-energy content, they will all be highly distorted.

These two reference frames can never be equivalent. If you are still
not convinced kindly consult the International Earth Rotation and

Sure they are. By "laws of physics" we mean equations like:

and not the happenstance of which objects are at rest in a given frame
(those are initial conditions, not laws).

You are confused. See above.

The use of the pejorative word "distorted" is inappropriate; these are
merely differences. And your example is just plain wrong at several
levels: an object has mass content, and that is independent of reference
frame. No object has any "energy content" except for its intrinsic mass;
energy is _NOT_ intrinsic to an object, it is a _relationship_ between
the object and a reference frame -- the energy of an object does indeed
depend on reference frame.
Post by GSS
These two reference frames can never be equivalent.
They indeed _ARE_ equivalent in the manner of interest: the laws of
physics are the same in both.

That is, one can apply F=dP/d\tau in either frame and
find it is satisfied. For a given physical situation
the values for the components of F and P will be
different, but the _relationship_ of that equation
will hold in each frame.

You suffer from two delusions: (1) You think relativity is complicated
enough that no one would have scrutinized relativity critically over
a period of one century, (2) You were the first person smart enough
for the task.

All you've shown is that by not understanding it, you can turn
something simple into a convoluted mess of inconsistencies. Special
relativity is nothing more than a four-dimensional affine space
equipped with an indefinite metric of signature 2. Since conservation
of energy, momentum, charge, etc., hinges on invariance under
spacetime and phase displacements, there can be no preferred frame,
since by definition, a preferred frame differs from frames which are
not preferred and therefore breaks the invariance.

Wrong. The indoctrination is an induced mental state which cannot be

I do not know the writer of EinsteinHoax. I read his article about
three years back and was quite impressed by it. Even though he is a
little too blunt, he represents millions of those scientists and
engineers who are intuitively convinced that there is something
seriously wrong with the Relativity Theories but cannot pinpoint
exactly what is wrong.
And this is what marks the difference between a scientist and a crank.

A scientist will look at a theory that appears strange and say, "Well,
*that* theory certainly looks peculiar. Let's find out if it's right,"
and then will design an experiment to test whether the predictions of
the theory are right or wrong. If several such experiments indicate
that the theory is right, then the scientist will say, "Well, nature
certainly behaves in peculiar ways, but it does appear that it behaves
this way."

A crank will get stuck on the "Well, *that* theory certainly looks
peculiar" stage and will never check whether nature really does behave
that way, peculiar or not. In so doing, the crank will insist that
nature must be as simple as he has preconceived it, and not
particularly care whether nature is really that way or not.

From what I've managed to get through of his postings, he starts out fine.
He takes himself seriously enough that he writes as if an authority, as if
authoring a textbook or lecturing to those more ignorant than himself.
And then he just goes horribly wrong.

But that should be expected the moment one starts reading of things like
"indoctrination", or scientists not demanding "deeper understanding". The
former, the plea of "Why is everyone stupid except for me?", is about the
surest sign of a crackpot-- if he disagrees with extant theory that
doesn't make him a crackpot, if he have a theory of his own that
doesn't make him a crackpot, but if he can't even understand why it
seemed like a good idea and caught on and has such staying power, then he
doesn't understand it well enough to presume to lecture about it. Failing
to understand, he assumes it must be the result of character flaws among a
worldwide community that makes it their job to study these things. As The
Bible says, the fool calls everything foolish.

For the latter, that scientists don't demand a "deeper understanding", I
can only presume he's completely ignorant of the hundred and one ways that
scientists have tried to interpret quantum mechanics-- Copenhagan, many
worlds, the transactional interpretation, pilot waves, and so on. The
sci.physics FAQ says more about that. As well as the reformulations of
quantum theory-- geometrically, complex probabilities, from gauge
transformations, exploring its relation to classical physics, and so on.
Buckets of ink have been consumed over these "deeper understanding"
issues, which could only have been missed if he'd never looked.

But no, he promotes himself as the lone voice in the wilderness who dares
to question conventional wisdom. He's not alone, and he's not very good
at it.

Yeah. As incredible as it may seem, these are not the Lorentz
transformations for length or time. But finding the transformation for
velocities by dividing the transformation for length by the transformation
for time is something that's done in every single undergraduate textbook
on special relativity, and in one of the last chapters of most freshman
physics texts. They also show how to transform accelerations and forces.

So how unrecognized is that? He took a standard exercise and claimed it
as his own innovation, something those poor, deluded PhDs had never

Yeah. As incredible as it may seem, these are not the Lorentz
transformations for length or time. But finding the transformation for
velocities by dividing the transformation for length by the transformation
for time is something that's done in every single undergraduate textbook
on special relativity, and in one of the last chapters of most freshman
physics texts. They also show how to transform accelerations and forces.
I must pick a nit here.
I wouldn't call that "dividing the transformations", but "applying

should get thoroughly explained.

So how unrecognized is that? He took a standard exercise and claimed it
as his own innovation, something those poor, deluded PhDs had never
thought of doing... and then he got the wrong answer.

But if you like finite ratios as much as Don does, you could also write

u' = delta x' / delta t'

= ((delta x + v delta t)/sqrt(1-v^2/c^2))

/ ((delta t + v delta x / c^2)/sqrt(1-v^2/c^2)

directly.
But indeed we already *have* the transformations of the
coordinate differentials, and we have them in both directions.
We are now looking for the transformation of the derivative of
some function x'(t') of the coordinates.
You just used one of the transformations yourself in the above
expression :-)

The idea is to calculate what happens with the coordinates of
a set of events (world line) given by some function x'(t'),
where we already know the derivative u(t) of the function x(t),
and where we know how the differentials dt' and dx' transform
as functions of the dt and dx.

Physicists and engineers always (and mathematicians sometimes)
leave out the function arguments and identify the function names
with the arguments. To do it properly we should write x' as
X'(T(t')), or even better, as [X'oT](t'). Bringing the function names
and arguments back in and using "correct" notation, using the
derivative operators d/dt and d/dt' [*] and writing them as d/dt[F]
as opposed to df/dt, we should apply the chain rule as follows:
u'(t') = d/dt'[X'oT] (t')
= d/dt[X'] (T(t')) * d/dt'[T] (t')
This is usually symbolically written as
u' = dx'/dt'
= dx'/dt * dt/dt'
where the arguments of the functions are left out as well.

The next step
dt/dt' = 1 / dt'/dt
which, using [I] and [1] for resp. the identity and the constant
function to 1, and T' for the inverse of T, can be properly
written down (and derived) as follows:
1 = [1] (t')
= d/dt'[I] (t')
= d/dt'[T'oT] (t')
= d/dt[T'] (T(t')) * d/dt'[T] (t')
from which
d/dt'[T] (t') = 1 / ( d/dt[T'] (T(t')) )
and symbolically, leaving out the argument t'
dt/dt' = 1 / dt'/dt

[*] Note: The letters t and t' in the operator symbols d/dt and
d/dt' are not argument letters. Writing the operators as D and D'
would be even more appropriate.

d/dt'(x'(x(x'(x,t),t'(x,t)),t(x'(x,t),t'(x,t)))

or continue that as far as you like. But the velocity in the primed frame
is the derivative of position in the primed frame with respect to time in
the primed frame, u'=dx'/dt'. If we have dx' and dt' in terms of x and t,
then there's nothing left to do except to plug them in. If we had x(q,r)
and t(q,r) and wanted to express u' in terms of q and r, that would be
different. But as the problem is stated, x and t are parameters, not
functions. You don't take the derivatives of parameters, you just plug
them in.

Using the chain rule gives you the right answer, as you've shown. It just
seems like an extra step that doesn't lend physical insight. dx'/dt is
mixing measurements across frames. I don't look at that and say "Aha!"

But that is the entire point I am trying to make :-)
When you want to describe the motion of a particle, you *do*
model an object's location x as a mathematical *function* of time t.
I introduced capital letters to prevent confusing the functions
with the arguments (coordinates), because all the coordinates
are all functions of one another, in one case as the world line
of an object, in another case through the transformation
equations.
We have for example the world line
X: R --> R: t --> X(t)
which is symbolically written as
x(t)
and, likewise a transformation function
T': RxX --> R: (t,x) --> T'(t,x) = g (t+ v x)
symbolically written as
t' = g (t+ v x)
etc...

As long as we are just working with coordinates, the 'short'
equations are perfectly okay and usable, but as soon as we
are going to calculate derivatives of world lines, it's good
to know what exactly we are doing.

You don't take the derivatives of parameters, you just plug
them in.
Indeed, we don't take the derivative of parameters.
We take the derivative of functions.
That's the point I am trying to make.

Using the chain rule gives you the right answer, as you've shown. It just
seems like an extra step that doesn't lend physical insight. dx'/dt is
mixing measurements across frames. I don't look at that and say "Aha!"
Well, actually dx'/dt is describing the position in the primed
frame as a function of the time in the unprimed frame. There
is nothing wrong with that, since each point has 4 numbers
associated with it x, t, x', and t'. In fact, it is essential part of
the derivation.

The next step
dt/dt' = 1 / dt'/dt
which, using [I] and [1] for resp. the identity and the constant
function to 1, and T' for the inverse of T, can be properly
1 = [1] (t')
= d/dt'[I] (t')
= d/dt'[T'oT] (t')
= d/dt[T'] (T(t')) * d/dt'[T] (t')
from which
d/dt'[T] (t') = 1 / ( d/dt[T'] (T(t')) )
and symbolically, leaving out the argument t'
dt/dt' = 1 / dt'/dt
[*] Note: The letters t and t' in the operator symbols d/dt and
d/dt' are not argument letters. Writing the operators as D and D'
would be even more appropriate.

= dx'/dt / dt'dt <== derivative of inverse
= d[g (x+v t) ] / dt / ( d[g (t + v dx)] / dt )
= g ( dx/dt + v ) / ( g (1 + v dx/dt) )
= ( dx/dt + v ) / ( 1 + v dx/dt )
= (u+v) / (1 + u v)

Yes, I had a look at these.
Excellent.
Now have another look at them and try to imagine that they
were written specifically with you in mind.
