I have forwarded yesterday your posting and it seems to me that Myron's message below should be interpreted as a reply. I am just a science writer but I have my limits and this has become a little too complicated for me to follow - thus I appreciate counterpoints and debates.
Gerhard W. Bruhn replied:
at first many thanks for your support.
It's a pitty that MWE refuses to discuss with me directly.
I shall wait a week whether MWE sends further mails and then reply
to all together. MWE's mail below gives no new point of view.
. . . With (*) MWE claims an equation with two different types of quantities on
both sides, i.e. a type mismatch, as if he would claim
apple = pear,
or if one would claim scalar = vector.
What Evans replies in his mail is not helpful. The only help would be
if he could explain why an apple is a pear or reversely.
But nobody is able to do that: The definitions of the two
(mathematical) fruits are different.
Now, Evans is a scholarly man who claims the Nobel prize for his
scientific work on his website. So he should help himself if possible.
Even if I could help him (but as explained above nobody can change
apples to pears) he would reject me with a lot of further polemics.
So there is no remedy for MWE, since, of course, only a real
magician could help him.

Hello,
Fine. One dispute. Go back to it later.
This man has done a tremendous amount of work that is consistent. He
is sick with a post traumatic stress disorder and needs help, not
strife at the present.
The fact remains that both Einstein and Cartan knew that the metric
needed torsion to allow for electromagnetism. Evans has found several
methods to add it. Help him, do not attack. Eventually you will find
common ground.
Write a supporting analysis article. Regardless of one detail that
can be cleared up, there are 20 places where agreement can be found.
Dig into it and show the antisymmetric metric exists. Ride coattails.
Gerhard W. Bruhn replied:
I do not know your educational background, so let it me say it at first very
simply:
Evans' theory lacks from a very essential point where it is
i n c o n s i s t e n t
, comparable with a three-legged chair
one legg of which is rotten: That chair looks like a chair,
but you cannot use it as a chair.
That rotten leg is the statement that
"if there exists a symmetric metric, then there must exist an
antisymmetric metric"

Gerhard W. Bruhn replied:
MWE uses mathematics as an essential tool to derive his "theory".
You will admit that without mathematics no GUFT would exist.
Therefore the validity of GUFT cannot be reduced to its experimental
evidence:
A necessary condition for its valitity is its formal
mathematical correctness.
So it's sufficient to point out examples of essential abuse of
mathematics in MWE's book-preprint. Evans is kindly requested to remove these monita (if
he can).
You have some knowledge of math (though - as I guess - you have no sufficient
knowledge about differential forms), therefore I can give you an example
closer to Evans' claim (*), which is of mathematical type, or what
do you think?
The type mismatch in (*) is closely related to an equation that claims
scalar = vector (in R3)
ω1 is a differential scalar while ω2 is of vector type.
ω1 = ds2 is the squared line element of a curve
(in Euclidean R3),
hence a number (=scalar).
The differential 2-form appears as the vectorial surface element of a surface in R3
normal to the direction (1,1,1) and hence is of vector type.
For that you should have a look at chap.5 (Vector Integration) of the
book "Vector Analysis" in Schaum's Outlines Series. Surface integrals
are treated with examples in the subsection SURFACE INTEGRALS.
The surface element is there denoted by dS (with CAPITAL S) not to be
mixed up with the line element ds that appears already at the end of
chap. 3. (I recommend to read chap.8 (Tensor Analysis) also, which will help a lot to
keep you away from mathematical errors.)
You can see the problem with MWE's equation (*) also from Carroll's book
http://arxiv.org/pdf/gr-qc/9712019
ω2 is another writing of the skew symmetric matrix
0 1 −1
−1 0 1
1 −1 0
which is the (0,2)-tensor εik in R3 that belongs to the "space"
Λ2 (Carroll p.21) while the line element (Carroll p.25) does not.
Concerning other errors of MWE's:
Did you ever read my criticisms on Evans' phaselaw paper in
http://www2.mathematik.tu-darmstadt.de/~bruhn/PHYSICAL_OPTICS1.htm
?
I doubt that. Otherwise you would have observed that the necessary condition of correct
calculations is
essentially violated also in that article on the level of elementary integration
calculus. Hence that article should have been withdrawn by Evans.
That's a realistic description of the present state of Evans' GUFT.
MWE to Lar Felker on Sun, 14 Nov 2004 19:30 +0100:
Gerhard Bruhn has a long record of incompetently attacking people. Since he asks, I think that Gerhard can resign from his job, and go back to school. My technical answers to Bruhn have been posted several times. They are as follows:Gerhard W. Bruhn replied:
I guess MWE has problems with reading or understanding texts accurately.
I neither denied
1) gμν gμν = 4 (for the 4-dim. case)
nor
2) e(1) × e(2) = i e(3)*
(or where???).
My argument is simply:
ω2 is a differential 2-form that cannot be equal to the scalar square
of the line element ds, i.e. to ω1 = ds2.
The equation (*) written in the terminology of Schaum's Outlines Series (Vector Analysis)means
ds2 = dS (Surface element of the surface x+y+z = const),
which is evidently erroneous!
However, we have some progress: We have limited the disagreement to one simple equation:
MWE claims
(*)
− [dx12 + dx22 + dx32]
= ds2 = dx1^dx2 + dx1^dx1 + dx3^dx1
to be true while I have argued that (*) in invalid due to type mismatch (see my remarks to
Dave Feustel above).
Additional remarks: Equation 1) is a simple consequence of the fact
that the matrices (gμν) and (gμν) are symmetric
and each the inverse of the other one: This yields
gμνgμρ = gνμgμρ
= δνρ ,
hence by equating the indices of δνρ
one obtains the sum of diagonal elements of the unit matrix
(δνρ),
i.e. the dimension of the involved manifold - 2 for a surface, 3 for a
3-dimensional manifold and 4 for a spacetime-manifold.
To attibute that as Einstein's discovery is surely exaggerated;
I would say it's "folklore".
On the other hand, MWE's result "=4" in 1) shows that MWE dealt with
4-dimensional spacetime.
MWE's equation 2) holds for a cyclic complex basis
in 3-dimensional space, since the cross-product yielding vectors again
cannot be extended to higher dimensions.
I suggest that MWE reduces his polemics in that situation and tries
to understand the facts.
MWE to Franklin and Dave on Tuesday 16 Nov 2004 14:31:
These notes are for a second appendix to the book and for posting on
www.aias.us. They prove straightforwardly that the existence of the well known tetrad
(vierbein) implies the existence of the symmetric and antisymetric metrics and the general
tensor metric. This is the eighth Bruhn rebuttal. (I have rebutted him five times, David
Hamilton once and, indirectly, Corneliu Ciubotariu once). In this case Bruhn made another
very trivial error which is corrected in my eqns. (17) and (18) of the attached.
In my opinion Bruhn is deliberately misrepresenting my work to this
group and to the world, because his errors are so trivial that no genuine professor of
mathematics would ever make them. This is why I feel that the appropriate disciplinary
action should be taken against Bruhn by his Chair and Dean. In other words these are not
genuine errors, but deliberate harassment. In my experience many appointments to academia
are made internally on a who you know basis, so are uncompetitive. The genuine scientists
are often left out in the cold, so must make their own wisdom.

Attachment: antisymmetricmetric.pdf (handwritten, title THE ANTISSYMMETRIC METRIC)
Gerhard W. Bruhn replied:
The attachment antisymmetricmetric.pdf deals with the 4-dimensional spacetime.
Therefore MWE has left now the R3-problem (*)
of p.23 of his preprint
http://www.aias.us/book01/chap2-cr3.pdf
without having given any satisfying reply.
Thus, the objection against (*) is not refuted.
MWE to all on Wednesday 17 Nov 2004 12:21:
Alejandro Buchmann,
Dean,
Informatics,
Technical Univeristy of Darmstadt,
Dear Dean Buchmann,
I wish to register a strong formal complaint against Dr. G. Bruhn and
request appropriate disciplinary action to be taken against him.
1) Dr Bruhn has made several trivially erroneous attacks against my work and in my opinion
this is defamatory. The repeated attacks amount to first degree harassment. This conduct
brings your University into disrepute becasue first degeree (or aggravated) harassment is a
felony. Any member of staff of a reputable university that commits a felony is normally
dismissed for misconduct.
2) Dr Bruhn has comandeered the e mail listing of the Alpha Foundation for Advanced Study
(AIAS), of which I am Director, and has spread this defamation to my colleagues. This has
annoyed and disturbed several of them.
3) Dr Bruhn has posted this defamation on websites and has approached scientific editors
in efforts to defame me. He has also approached one colleague at CERN, Dr Caspers, with the
same intent.
The work of AIAS has attracted one and a half million hits this year and
is rigorously correct, being based on differential geometry. Others and myself have
corrected Bruhn on several occasions, but his harassment and defamation continues. His
conduct reveals that he is technically not able to assess scientific work. We at AIAS find
his repeated defamation offensive and unscientific.
Appropriate disciplinary action would be dismissal, loss of salary,
benefits and pension.
Cordially Yours,
Myron W. Evans,
AIAS Director.
Gerhard W. Bruhn replied:
A remarkable contribution of MWE to scientific discussion, really!
After that intermezzo back to science:
You'll find the GAP in
http://www.aias.us/book01/chap2-cr3.pdf
on p.22 between the eqns. (2.7) and (2.8). The statement
«
Because εk is dual to εij by geometry,
then qkr(S)εr
must be dual to qij(A).»
is still correct. But then it follows a verbal attempt of justifying (2.9) starting with
«
So ... » without any arithmetical justification.
That missing calculation is the GAP.
Of course, the 2-form − ½ qij(A) dxi^dxj
exists (why not?). But it cannot be equated with ds2.
MWE is kindly asked to close the gap by a convincing calculation - if possible.
The 4-dimensional case is treated by MWE with the eqns. (2.16) and (2.17).
While (2.16) is correct equ. (2.17) shows the analogous type mismatch: Writing out (2.17)
by using the matrices (2.14) and (2.15) we obtain as Evans' claim here
(**)
dx02 −
dx12 −
dx22 −
dx32
= 1/3
[dx0^dx1 + dx0^dx2 + dx0^dx3
+ dx1^dx2
+ dx2^dx3
+ dx3^dx1] .
No matter how, this type mismatch cannot be removed by
aposteriori explanations as in MWE's article antisymmetricmetric.pdf .
