Dear Scott, Dave & Richard,
plus the rest of the professional group,
just what is the purpose of a conference? In the last years I have gone to as
many conferences as I could, but the purported objective of a conference -
discussion - simply does not materialize. A conference is just a series of
monocussions, and people perceived as dissenters will be delegated to the poster
session where only uninformed graduate students show up. To be sure, they can
think, but their opinion does not matter. Conferences are useless, they are just
social meetings.
If you ask the more sceptical thinkers in structure you will find sufficient
support for my contention that since 1975 we surely have learned better and
better to describe what we see, but we have not made much progress in
understanding how it came about. Dave's (truly excellent) backscattering
scanning method is a valid case in point. What you do is poking in the dark with
highly sophisticated sticks. If you improve your methods you develop longer
sticks. What you need is more light.
So where is the switch? In the theory. I have done my best to make it known that
I disagree with the current theory of stress and deformation. Among other points
I can predict
- the geometric properties and the full kinematics of S-C fabrics,
- the obliquity of microfabrics in shear zones,
- the observed orientation of max stress along the San Andreas Fault which
is at 80° to the fault, rather than the expected 45°,
- a variety of so far enigmatic properties of elastic deformation,
- and the curious pattern in the energetics of deformation: experiments
show that elastic simple shear requires >10% _more_ energy per unit strain
than elastic pure shear, whereas plastic simple shear takes ca.30% _less_
energy per unit strain than plastic pure shear,
- and I can give a reason why cylindrical folds with axes // Y will decay in
extended plastic flow to form sheath folds // X.
So what do you guys do? After 14 years of effort it has yet to happen that the
first colleague from structural geology asks me a question. They say they don't
understand, but get evasive if I ask just what it is they don't understand.
Submitting papers is useless too, they "cannot find reviewers". Fact is, you
don't want to know where the switch is. By all your behavior over the years it
is perfectly clear that you would readily board a plane scheduled to fly into a
sky scraper rather than get involved in a discussion of the theory of stress and
deformation.
I have published mathematial proof that the stress tensor does not exist. This
does not mean that stress does not exist, but it does mean that you have no clue
what stress is. I have published an exhaustive critique of the theory we have.
The silence around me has only become deeper, apparently you want to be told by
someone else whose authority you can trust if this is for real. But there is
no one else, use your own brain. If someone disagrees with my views it would be
professional to formally shoot me down. Nobody has done that. My theory plus the
predictions are on my homepage for everybody to inspect.
It is a trivial matter to prove that the theory of elasticity is profoundly
incompatible with the theory of potentials (which is the backbone of all of
classical physics). Potential theory says that the divergence is "a measure of
the work done upon a system" of mass. Elasticity says that the trace of the
stress tensor, or the divergence of the stress vector, is zero for a
volume-neutral deformation. Hence the theory of elasticity predicts that no work
is done. But try to publish your objection, "this journal is not a place for
heated arguments".
Back to marshmallows.
