The names of Harold Slusher and Thomas Barnes have cropped up in these
postings concerning MIOS, the Metroplex Institute of Origin Science.
In his book "Science and Earth History", Arthur Strahler gives
excellent synopses of both men's theories. For those interested in
the creation/evolution controversy, this is THE book. At around $40
it is a bargain by one of the top science textbook writers. It is a
thick, large format, hard-bound book with lots of illustrations. It's
from Prometheus Books, the publishing company owned by Paul Kurtz of
CSICOP. If you are an NCSE member you can order it from them at a
discount.
Someone asked how to join the NCSE and get their newsletter. If you
haven't received a reply yet, drop me a note and I will fill you in
when I get back from my meeting (around noon).

As part of my follow up I purchased a copy of the Slusher/Wells
Outline. As far as I could tell, the authors provide a
creditable treatment of undergraduate physics. The examples and
the problems are meaningful and clearly stated. There is no
coverage of quantum mechanics or relativity, but I would
recommend the book to any undergraduate studying physics or
engineering mechanics. One would never know that one of the
authors holds such a low opinion of the title subject.
I think that McGraw-Hill is doing a disservice listing Slusher as
a Ph.D. on the title page. Although one could argue that
professional titles are worthless in themselves; it's only the
works of the person that count. If this is the case, then why
list the professional titles? Helps to sell books. This smacks
of false advertising in that case. The UTEP undergraduate
catalog doesn't list Slusher's Ph.D. McGraw-Hill should correct
the problem.

After looking at the monographs of Slusher that Taner Edis forwarded I can
only say that I am appalled. The fact that special relativity only applies
to inertial reference frames is something that is normally drummed home in
the first year of an undergraduate course in physics. That someone in Slusher's
position seems to have lost sight of this is, to say the least , disconcerting.
Does anybody know if the Schaum book suffers because of it? (I'm going to see
if I can track a copy down over lunch, but I probably won't have time to do
more than skim over it.)

I received my B.S. from U. T. El Paso. I took a course under
Harold Slusher and two courses under Dr. Thomas Barnes (who is
also a proponent of creationism.)
Both men are intelligent and both teach their courses with almost
no reference to creationism.
They understand that had they pushed their personal ideas in the
classroom they would probably have been fired.
Barnes taught the best two courses in E&M I ever had.
Both can follow the status quo very well and understand it perfectly,
but it seems they feel that they have had some special insight into
the "TRUE" nature of the universe that only they have had.
Years ago I approached both privately on the subject of creationism.
They became very animated and really tried to explain the essence of
their understanding. (It didn't take.)
Out of several hundred students, maybe four or five "understood" and
became members of their fold. Which to them was just right. Only the
elite really understand.
This of course allows them to be impervious to all attacks. They
consider all attacks as coming from ignorance and misunderstanding.
They have created their own confortable, secure little world and
are happy therein.
I would only attend a lecture of this nature if I had not been
previously exposed to a creationist.

Pretty typical creationist abuse of physics.

Both suspicions are correct, i.e. his thermodynamics fails on
account of making up a nonsensical equation, and his relativity
totally ignores the acceleration. The details follow after Slusher's
arguments:

Separation of entropy into "random" and "order" parts is bad
enough (I'd like to see what distinction is to be employed), and it is
made worse by pulling what amounts to a "conservation of order" law
out of a hat. This is garbage, and has only a tenuous connection to
real statistical mechanics.
As usual, what is attempted is a rephrasing of the classical
argument from design, but in quasi-physical language. Unfortunately,
the evolution of functional complexity in dynamical systems that can
be described quite simply has been known for a while now. Natural
selection in a biological context is but one (early) example of
general "self-organizing" behavior.
Entropy is a concept very strongly tied to information and
complexity. Perhaps a description of how a "2nd law" operates in
informational terms can be useful:
All "microscopic" physical theories we currently think well of
have an "information-preserving" quality: complexity is not created
(say by random injection of new particles) or destroyed (which is just
creation in a time-reversed sense). The natural question is how can
so many of our *macroscopic* theories be very successful, when they
very often include an irreversibility in time? Slusher's
natural/unnatural event description assumes this: normally things run
down and decay (entropy is increased, complexity lessened), while some
events he "explains" by invoking design involves generation of "order"
(entropy goes down, complexity goes up).
The standard reply is that nothing in a global picture of
increasing "disorder" prevents local fluctuation. This is entirely
correct, and not affected by bogus conservation laws, but there is
more to the story, i.e. how we can get irreversibility in a seemingly
reversible universe. It would seem that global entropy does not
change at all!
What saves the day is the observation that humans and similar
information processors cannot handle the infinite amounts of
information necessary to perfectly track the time evolution of most
physical systems. *The presence of dynamical randomness -- chaos --
will create irreversibility from the point of view of a finite
information processor*. In fact, one can justify many irreversible
phenomenological equations that are irreversible (such as diffusion),
based on reversible dynamics that possess a positive Kolmogorov-Sinai
entropy (a relative of conventional entropy that is useful for chaos).
In other words, a physical theory that posits a constant
complexity can still give rise to increases and decreases in "order,"
at a macroscopic level where only finite computational resources are
available. A macroscopic decrease in entropy is not the same thing as
a microscopic complexity increase. Self-organization can and does
occur, just like disorganization does, neither are "unnatural."
Slusher's distinction between "kinds" of entropy is
ill-defined (reminding me of the creationist "kind" concept in their
version of biology), and no conservation law of the form invoked
exists.

Special relativity declares that only relative motion is
meaningful for *inertial* frames of reference, i.e. those at
*constant* velocity. Once acceleration (or, equivalently,
gravitation) is present, it is general relativity that must be
invoked. Dingle's argument fails on this count, in that the purported
illegal distinction between frames is entirely based on the
acceleration, invalidating the assumption of inertiality.
There is a very closely related, but more dramatic puzzler
about special relativity, the "Twin Paradox." This is traditionally
sprung on undergraduates just when they think they conceptually
understand relativity, after having performed a few Lorentz
transforms. Remember the well-known illustration of time dilation
(where the elapsed time between events depends on the relative
velocities), that of the astronaut zooming through space close to the
speed of light? Well, she comes home after a year of her time, in
which her twin has aged twenty years. But then, you spring the
question on the unsuspecting (they never do) students: if only the
relative velocity of the frames (rocket and earth) matter, is it not
the case that the earth twin is traveling very fast relative to the
one in the rocket? In this case, why doesn't the earth twin age one
year to the rockets' twenty?
Again, the distinguishability, allowing us to point at one
twin as getting older than the other, has to do with acceleration --
special relativity doesn't apply. If the twins were on separate
rocket ships all their lives, going at constant velocity, fine, except
that they'd never meet again. In order to meet again, the rocket twin
has to decelerate at some point in his journey, reverse velocities,
and head back to the home planet. At this point, you can roughly
calculate the aging difference from special relativity, but the
equivalence of frames is destroyed -- by the huge mass of the earth.
The Doppler shift pseudoproblem is essentially the same thing,
and is no argument against special relativity. And in cosmological
questions, it is general relativity that is indispensable, where the
general Doppler shift is related also to the curvature in space-time.
Talking about Doppler shifts giving the velocities at the time
of observation is nonsense, and not only because of Dingle's
misunderstanding of the theory he criticizes: it smuggles in a notion
of a "now" that is the same across the universe -- the time of
observation -- that is at best a conceptual roadblock in a
relativistic universe.

Columbia Pacific University is a "diploma mill", but I think it is
"better" (if I can use that word) than most. Rather than merely mailing
you a diploma in return for your check, they actually go thru the motions
of providing some instruction. For a Ph.D., for example, you are supposed
to conduct research at your location (not at theirs) and enlist the
aid of a local expert in your field, all the while maintaining contact with
your CPU advisor. In due course, you will receive your degree.

In Dallas there is a local creationist group called the Metroplex
Institute of Origin Science (MIOS). The hold monthly meetings at
which they preach the evils of evolution and host lectures generally
aimed at discrediting legitimate science, particularly as it supports
1) biological evolution of species, 2) modern concepts in geology (old
age of the earth, natural processes accounting for geological
phenomena, etc.) and 3) modern concepts in cosmology (Big Bang, etc.).
They seem to believe emphatically that the earth is about 6000 years
old, the flood of Noah was a real event just as described, and humans
and dinosaurs lived contemporaneously, as evidenced by the so-called
"man tracks" in Cretaceous limestone in the Paluxy River about 90
miles west of here.
Don Patton, chairman of MIOS has informed me that the lecture on
Tuesday night next week (election day) will be Harold Slusher. Harold
Slusher is a well known proponent of "creation science". He has a
legitimate master's degree in physics and is the co-author of the
Schaum's Outline "Physics for Engineers and Scientists" (I believe
that is the title). He claims to have a Ph.D. in geophysics from
Columbia Pacific University. He is an assistant professor of physics
at the University of Texas at El Paso. Here is some additional
information: 1) He lists his "Ph.D." on the title page of the
Schaum's Outline, but the UTEP undergraduate catalog does not list any
Ph.D. 2) I can't find "Columbia Pacific University" in any college
reference. 3) He is the author of a monograph titled "The Origin of
the Universe: An Examination of the Big Bang and Steady State
Cosmogonies" in which he generally bashes modern cosmology and makes
some bizarre statements concerning special relativity.
Can anyone on this forum provide me with additional information
regarding Slusher and his claims? I plan to attend the MIOS meeting
on Tuesday and make a first hand assessment. I would appreciate any
assistance.
Fellow North Texas Skeptic, Ron Hastings, will hopefully be there, as
well. Ron has a (real) Ph.D. in physics from Texas A&M University,
and he is on the board of directors of NCSE, the National Center for
Science Education. He is one of the better authorities on the Paluxy
River "man tracks" (see Arthur Strahler's book, "Science and Earth
History"). Even so, we could use some help.
If anybody is interested, please drop me a note. If you would like, I
can supply you with specific excerpts from Slusher's monograph for
your own evaluation. Taner Edis, this should be your concern. It is
the science of physics that's being trashed.

In my previous post I didn't explain my relief at encountering
old earth creationism. Our problem here (Dallas area) is not
only countering anti-evolution propaganda but also having to
argue that the Cretaceous limestone that abounds in these parts
is really more than 6,000 years old. Local creationists seem
to have given up entirely on science.
Speaking of local creationists, I will be attending the meeting
of MIOS, the Metroplex Institute of Origin Science, on Tuesday.
If anyone in the area is interested I can provide directions.
