Andy, I don't think that is possible.  (E and B) exist as the
(sine-cosine) time rate of change of the other.  In free space (E = cB)
where c is the velocity of light. 
 Interestingly, the traveling wave of EM radiation has a (paradoxical)
(sine-sine) relationship between the (E and B).  
The (sine-sine) (E and B)   can be shown to result (relativistically) from
the EM being the coupling of two conjugate (E, B) and (B, E) in space
quadrature.  It is then relativistic effects that give the optical
illusion * both* (E and B) of the EM radiation go to zero simultaneously. 
This apparent (E and B) disappearance  is, of course,   absurd  (energy
cannot disappear without being replaced with matter).  
The lateral (sine-sine) (E and B) transform into a resulting  Poynting
vector with maximum axial amplitude.  The axial Poynting vector  is then 
Lorentz-Fitsgerald contracted,  as viewed from our stationary frame of
reference, thus causing the optical illusion of the disappearance of (E
and B) we see in the EM traveling wave.  
I have shown these arguments on the web page:

Dom,
Basically, your equation (2) is incorrect, "k" should be K-T rather than 
K+T. I prefer not to use T as it is dependent on H and K (equation 6.) The 
correct ones follow:
[hkl] 
and Miller-Bravais by 
[HKTL]
then the geometric relations between them are:
1) h=2H+K
2) k=2K+H
3) l=L
4) H=(2h-k)/3
5) K=(2k-h)/3
6) T=-(H+K)
7) L=l

I'm thinking some kind of static electric charge.  But I'm only thinking
very vaguely. Maybe the charge keeps them apart or something.
I'm also thinking surface tensions of the material to form the
embedding media.  Maybe when it is liquid it has a surface tension
that will tend to want to insert itself into the spaces between
the fibres, pushing them apart.  Maybe you need to adjust the
surface roughness of the fibres, or the surface tension of the
liquid.
I'm also thinking the fibres and the embedding material should have the
same density.

Dear Christian -
At the university level, books for the FE (formerly E-I-T) exam are
always popular. In fact, many univ. libraries won't circulate them
because they "walk".
Of course, I'd love to see you buy one of the books I've written, 
but there are others out there, as well. 
I don't think books for the PE exam are necessary in your collection,
unless you were getting them for professors.
How else can I help?

He may have been overselling slightly.  I'm not an expert on this
business, but from what I understand of the recent duality results, they
don't bring us much closer to the real world.  What's been proven is
that what previously seemed to be five different string theories (type
I, type IIA, type IIB, the heterotic string, and something called
M-theory) are actually just different phases of one underlying theory.
Now, while this is exciting, it doesn't bring us any closer to, say,
deriving the particle content, masses, and coupling constants.  That
probably won't be accomplished until we can make some progress on actually
*solving* this theory, i.e. calculating how the extra dimensions
compactify, etc.  Which seems to be a long way off.

Whoa!  The fibers must be mostly evenly spaced and mostly parallel.  It 
is not a question of an image being coherently transmitted rod end to

Yo!  100-500 feet of rod/week.  "Vaguely" won't do it.  Even "absolutely"

The 6 micron fibers are drawn smooth, the liquid monomer will react to 
solid, and wetting attracts fibers together until they touch.  Of course, 
if the fibers do not wet they will not pot as the resin contracts during 
polymerization.

The lungs, ear drums, and surface capillaries rupture as the eyes 
freeze-dry and the tongue swells.  You may also get gastric, rectal and  
bladder voiding.  The abdomen will swell, but probably not to 
bursting,  The rest of the organism is very well compartmentalized.  
After death it will cool to freezing while dehydrating, then proceed

Here's a start, IMHO, for Chem E topics:
* CRC Handbook of Chemistry and Physics
* Merck Index
* Perry's Chemical Engineers' Handbook
* McCabe & Smith "Unit Operations of Chermical Engineering"
* Luyben "Process Modeling Simulation and Control for Chemical
Engineers" (BTW, I hear that Luyben and son have a new book... is that
out yet?)
* Numerical Recipes in C/FORTRAN
* Bird, Stewart, & Lightfoot "Transport Phenomena"
As far as Thermo, I have Balzhiser, but I didn't really like it.  I
hear Smith and VanNess is better.

In astrodynamics I really enjoy using "Fundamentals of Astrodynamics" by 
Bate, Mueller and White.  This is an excellent soft cover book.  For 
designing satellite missions try "Space Mission Analysis and Design" by 
Wertz and Larson.  For the numerical analysis I really use "Numberical 
Recipes in FORTRAN (or C, or Pascal)" by Press, Teukolsky, Vetterling 
and Flannery.  Recently I have read criticism about some of the 
algorithms presented in this book.  Usually for not being the most 
robust or the best answer for specific cases.  However, in general I 
believe it is an excellent book.  The authors explain the theory and the 
basis for their selection and provide ample other references if the user 
needs further guidance.

Herve, 
How shall you do sciences?  Start by learning all you can (= The Whole 
Truth) about a field before you attempt to prove it is invalid.  I 
checked 3 QM textbooks and none of them claim that the 4s orbital is 
filled before the 3d orbital, *except* in the limited case of the 
neutral gas-phase atoms of the 4th row of the periodic table.  
The Whole Truth, as Steven and I have pointed out, is that the 4s is 
filled before the 3d only in the special case of the valence shell of 
neutral atoms.  This is the Partial Truth we were all taught in General 
Chemistry.  The Whole Truth is rather more complex. 
In fact, your own web page illustrates this in Fig. 3 of the French 
version (http://www.afuu.fr:80/hcl/aip/p5-8.html).  The 3d and 4s 
energies cross over at Z=3 and then back again at Z=20.  (I don't read 
French very well, but that looks like the energy levels for a 
semi-empirical MO method?  If so, they are numerical approximations of 
QM results for the convenience of computers, and are irrelevant to the 
validity of QM itself.)
Extraordinary claims require extraordinary proof.  I think "Quantum 
mechanics is wrong" is an extraordinary claim.

  Try this. On the Real number line two points multiplied gives another
point because we have 0.000....  as a reference.
  So the trouble with squaring ...111111.1111... is that we have no
reference in Loba geometry. And although we have ....00000.0000..... as
a point in that geometry, apparently multiplying by ....0000.000... in
Loba geometry does not always give ....0000.0000....
  So how do we build a reference point? In Euclidean Geometry it is so
obvious that it escapes the attention of most since 0 is the
intersection of the three axes of Reals, i , and j.
 So is there a reference point in Loba and Riemannian geometry that
allows us then to multiply in those geometries? Of course there is,
once you picture those geometries. And you need Quantum Physics to
picture them.
  Riemannian geometry is elliptical or circular in the special case.
But not only is it the surface of a sphere that is its trademark or
hallmark. It is also its discreteness. Euclidean geometry is
continuous. Riemannian geometry is discrete and the way to picture that
is that the p-adics or better called All-adics are discrete. The
2-adics are one ball discrete from the 3-adics which is another ball,
discrete from the 4-adics which is another ball. So if you want to
picture the All-adics, you can picture a large number of discrete
balls. You could even say that the 2-adics are a particle and that the
3-adics another particle distinct. But let me get to the Loba geometry
of doubly infinites.
   You look at a doubly infinite such as 
           ....111111.1111........
  and you can sort of think of the leftward string as a p-adic and the
rightward string as a Real. Sort of look at a Doubly Infinite as a mix
or hybrid of a p-adic and a Real number. But it is not. It is a number
that is a point in Loba geometry and has no resemblance to a Real or
p-adic or a hybrid of the two. This is David's mistake. He has to see
every number as a Real number.
   So what is the square of the Doubly Infinite number
.....1111.1111....
The square of any point in Euclidean 3-Space is easy because we have
the 0.000..
as a reference point and then can define a vector product or dot
product. But what would a reference point in Loba be?
   Picture the Riemannian geometry as a infinite series of balls, each
one of those adics forms a ball, the surface of a sphere.
  Now, picture Loba not as a disc as a fair number of math people would
picture it as a disc, and not as a saddle, or horse saddle infinite in
reach. But the best way to picture Loba geometry in connection with the
Riem geom of balls is to picture Loba as a infinite reach surface of a
trumpet. And then to fit one of those p-adic balls inside the trumpet.
   Thus for squaring   ....11111.111....  we would have to know what
p-adic is the .....11111. portion. Is it a 2-adic. We need no
additional information about the Real portion of .1111111 except to
know where the decimal point is and the radix point in the string is.
  Now then, do you have the trumpet in mind with a p-adic ball inside?
Now we can begin to see and look for a point of reference for the
Lobachevskian geometry. A point of reference as useful to Loba geom as
0.0000.... is useful to Euclidean Real geometry and allows us to
multiply in Euclid geometry without any difficulty at all because we
take for granted that 0 reference point. In Loba. geometry the
reference point is a bit trickier. And the reference point is probably
imaginary to the Loba geometry. We have two imaginary numbers in Real
Numbers in order to get us a Euclidean 3-Space. So the fact that we
need an imaginary number in Loba geometry in order to 
    Collate any two Doubly Infinite numbers
is not new.
   So David, I am not going to do all the work here. Let me see you
arrive at some decent multiplication after telling me what p or n adic
string is your
...........11111111111111111111.   ? Is that a 2-adic or a 3-adic or
10-adic?
 Once you have specified which adic that is, then make a reasonable
guess as to what a point of reference would be with a adic ball inside
a larger object of a Loba Trumpet, the surface of a trumpet.  Once you
specified the point of reference, and make your specification so good
that it is applicable to all 2-adics if your ball is a 2-adic.
  Once you have that special point of reference for Loba geometry, then
you can multiply or square your ....1111.1111.... and arrive at another
Doubly Infinite number.
  As I stated earlier, it is very important to recognize that in Doubly
Infinites as well as in Loba geometry that when you multiply by
...0000.0000... which we think is the zero of Reals but is not. It is
important to recognize that in Loba the product of ...000.0000.... is
not .....0000.0000..... In Reals, the product of any Real by 0 is of
course 0. And the physics behind that Loba product of a zero being not
zero is important, for it means to say you can get something out of
nothing quite naturally.
  So give the above your best shot there David Madore. Remember, the
world is watching.

    Newton's Law states that for every action there is a reaction.
Perhaps in contact or collisional interactions this can be reduced to
the principle that no two abjects can occupy the same place at the same
time? As one object or atom in motion approaches a stationary atom or
object, it decelerates? For every action there is an equal and opposite
reaction. The rate of change of decrease of the inertial field of the
moving atom as it decelerates equals the rate of change of increase in 
the inertial field of the stationary atom as it accelerates?

  This is what I mean about a career in mathematics and in the USA. A
career in mathematics is the social and academic equivalent of
perpetually fighting a Vietnam war. We see it in the Unabomber. We see
it in Andrew Wiles disregarding the Calif. math journal and publishing
in his own hometown journal and then ignoring all complaints about his
alleged proof.
  And we see it in University of Wisconsin. Tell us there Brent
Hetherwick, how much money have you spent already in your so-called
education and why they never taught you any manners there at Univ. of
Wisconsion for that type of language is a fair cross section of the
type of language and education math people earn here in the USA. Now
some people in foreign countries who are thinking of coming over here
to school in the USA and studying math think about the muggings after
class or the fights in class. And they may think that Univ. of
Wisconsin is out in the sticks and not at all like Harvard or Princeton
but that is not true. There is blight, and high cost of education there
as well as at Univ. of Wisconsin. And the language that Brent displays
is somewhat toned down from a Freshman to Junior, he is probably a

Sorry. I do not agree at all. I am not working in the field, which would probably imply I was a teacher, but I 
have been thinking fairly heavily about QM for a very long time. I think the problem is that QM provides a 
surprisingly usefull mechanism, especially considering it's simplicity. But it does not provide sufficient 
understanding of why it should work to lead us to an understanding of what exactly can be done with it. An 
example might help. The model used for standard superconductors, Cooper pairs as I recall. You can't exactly 
say that QM doesn't work here, but you must ask, Why do Cooper pairs exist at all, if they do, and why not for 
the HT superconductors, which I seem to remember use a different mechanism, And if Cooper pairs, and HT 
whatevers, then what else may exist? Can I force QM arrays of thousands of electrons, or other particles? You 
see that QM offers a mechanism, and under some conditions permits calculations, but as a theory it is a bit 
parsimonious. Sort of like a list of all english words is to Shakespear. We may not exactly have found any 
clear case where only  will express the play, but that does not make QM a TOE.

Dear Chris. Gravity is not actually known to travel at all. It may be deduced that it probably travels at 
C, in waves, because we have a lot of experience with things that do that, sort of. It is very unlikely 
that it propagates at any other speed, for a number of vague reasons. The experiments that are looking for 
gravity waves seem to be just a bit too clumsy, if they really exist. Any way, they have not confirmed any

This can't be right.  The first transform is not the inverse of the second.
2 and 6 imply k=-H.  The simplest way to fix it is to change 2 to k=K-T.

Not the way you've written it.  The reverse transformation would give you
[3,-2,0] unless you fix the sign in 2, in which case it turns into
[3,0,0], which of course is the same direction as [1,0,0].

 Why Mind Control Is Also Lives control?
(Part Five)
"What kinds of artificial diseases could be induced on old people
or young people by mind control operatrs?"
I have stated that current mind control system are also lives 
control system.  Therefore, the operators will distinguish people's 
lives into different groups in the society.
After operators have distiguished people's lives into young or old 
group, the operators will induce different diseases to these two 
different group people. 
To maniplate the old people's lives in the society, the operators 
always use the invisible wave weapon to induce the the Parkinson's
disease or Alzheimer's disease on them.
I would clarify it now.
12/31/95,  the chinese WORLD JOURNAL reported a news article 
from NEW YORK TIMES.  It is as below.,
========================================================
"The Alzheimer's disease and the Parkinson's disease are horrible
However, reducing the bad condition, one must take medician with 
strong struggle will."
There are five hundred thousand to a million people who have 
Parkinson's disease in US.   This is an unknown nervous system
disease. There are fifty thousand people--almost over fifty years
old --appear the symptoms of it or count as Parkinson's disease for
unknown reason.
Parkinson's disease will happen when people lost the brain cells of 
central nervous system which control movement.  Such kinds od cells 
can produce the so called "Dopamine" material which can transmit the 
brain's command to impair normal motor skill.  If people lack the
Dopamine, they will appear shake uncontrollably (tremor), muscle
stiffness (spasm), slow movement, lost of equilibrium (cannot 
maintain balance), sometimes incorrectly spoken of as "palsy" ,etc.
Generally the early symptoms are not so clear, however, the physical 
condition will be deterioriate annualy. one third of patients will 
also develope the Alzheimer's disease.  The patients who have 
Parkinson disease are three times more likely than normal elderly
to develop Alzhemiser's disease.......
==========================================
According to above report, We know that the Parkinson's disease is a 
unknown nervous system diusease.   It is mostly caused by losing the 
brain cells of central nervous system which can produce the "Dopamine." 
Why is it a unknown nervous system disease?
That's because medical community cannot find the real reason why 
people lost this kind of brain cells.
Now, I would further clarify my words below.
I didn't say that the Parkinson's disease must be caused by mind 
machine operators' attack.  However, I say that the machine operators
can use the chronal gun to damage the tissues of brain cells of central
nervous system directly or the realated acupuncture point to cause the
victims appearing the symtoms of Parkinson's disease.
The enclosed information proves that the acupuncture point of
human body can introduce onto the human brain nervous system. 
(attachment)
======================================
The 1988 book, PSYCHIC WARFARE--FACT OR FICTION, edited by John 
White, carried several articles by Thomas E. Bearden, leading U.S.
expert on Soviet Tesla and psychotronic weapons. In his article
titled, "Soviet Psychotronic Weapons, A Condensed Background,
" Bearden stated: "The psychotronic patterns/effects can be
modulated onto electromagnetic signals, even of very low intensity"
(such as ELF and VLF), "and still affect living systems because of the
KINDLING EFFECTS; i.e. the psychotronic virtual state modulations are
stripped off by a living system (IN THE ACUPUNCTURE POINTS NEAR THE
SURFACE OF THE SKIN) and introduced onto the human nervous system
where they begin to superpose coherently as time passes. Such
collection eventually reach the quantum threshold and OBSERVABLE
PHYSICAL CHANGE RESULTS."
"...By modulating psychotronic (PT) signals onto electromagnetic 
(EM) carriers, visible light squelching can be overcome. The PT
modulations are then delivered to the bio-logical (or material)
targets through the light--photons go right through other photons
without interaction except in the most extreme cases--and ACTIVATE
THE ACUPUNCTURE POINTS." Soviet physicist, "Victor Adamenko,
discovered that acupuncture points form plexuses or groupings, THAT
ARE FREQUENTLY SENSITIVE. Further, these plexuses are coordinated
with and to specific body locations. BY CHOICE OF FREQUENCY, ONE
CAN THEREFORE DETERMINE WHAT PART OF THE TARGET'S BODY IS EFFECTED."
(The New World Order & ELF Psychotronic Tyranny by C. B. Baker)
=====================================================
So the patients with Parkinson's disease might be developed because 
natural causes but the reasons of such cases belong to unknown. 
On the other hand, we know that the mind machine operators can use 
the invisible wave weapon ( such as chronal gun) to creat
artificial Parkinson's disease patients.
  The reason is that their chronal gun bullets can damage the 
tissues of brain cells directly.   If the operators destroy the 
enough brain cells (which control motor skill) of people, then the
victims can also have the symptoms of Parkinson's disease ( If the
patients really have parkinson disease, it is the disease that destroy
the brain cells.  If the victims of machine operators have the 
symptom of Parkinson disease, thge brain cells are destroyed by chronal
gun bullets).
The operators also can use the chronal gun bullets to strike on the
people's acupiuncture point (which is realted with brain neverous 
system) to induce the system of Parkinson (such kind of acupuncture 
points are most on the back of head).
Furthermore, If the victims ages are over fifty, the machine operators 
will try to induce the artificial Parkinson disease to these victims 
(By taking the advantage of existance of Parkinson disease, the
operators can attack the victims' brain to induce the artificial
Parkinson's disease. It can destroy people without attracting other
people's attention).
 Also the machine operators can use their invisible wave weapon to 
attack the old victim' memories to induce the artificial Alzheimer's
disease.  That's because their chronal gun or infrasound weapon can
damage or destroy the victims' brain cells that store the memories.     
So the Alzheimer's disease might be resulted by natural cause. 
However, this kind of disease also can be taken advantage by the
mind control operators.
The operators can destory the old victims' memories with the
invisible wave weapon ( such as chronal gun or infrasound) without
attracting other people's attention.
Some operators will also use the invisible wave weapon to induce the
kidney faliure or heart failure disease on old people.
Such kind of injury will be used the chronal gun (on low set) or
infrasound to attack the kidney of old people in order to avoid the
attention from victims.
That's because old people got the kidney failure disease or heart 
failure disease to die will be easily accepted by others as if
the natural death (which is caused by natural factors).
Therefore, the operators can commit their crime without attracting 
the attention from the society.
To manipulate the young people's lives, the operators frequetly use the
mind machine to induce the artificial sex dreams and then use the 
chronal gun to cause young victims ejaculation.
I would show readers such kinds of mind machine information below:

============================================
DEFENSE ELECTRONICS reported that a Richmond, Virginia firm,
Psychotechnologies (believed to be closely tied to the CIA and the FBI)
has purchased the American rights to the Soviet mind-control devices.
DEFENSE ELECTRONICS described a spring, 1993 meeting between Clinton
Administration officials and Soviets psychotronics experts, including
Dr. Igor Smirnov. Amongst the U.S. agencies represented at the meetings
with Smirnov were the FBI, the CIA, the Defense Intelligence Agency, and
the Advance Research Projects Research Agency (ARPA). Clinton
Adiministration officials wanted "to determine whether
psycho-correction...programs COULD BE UNDERTAKEN BY THE U.S. GOVERNMENT.
These devices could be used to AFFECT JUDGMENT OR OPINION OF
DECISION-makers, KEY PERSONAL OR POPULACES."
Also meeting with the Soviet psychotronic experts, were officials from
the giant Trilateral-allied international corporations, such as Genweral
Motors and researchers from the National Institute of Mental Health. 
The 3\23\94 WASHINGTON POST reported: "The Pentagon and the Justice
Department have agreed to share state-of-the-art military technology with
civilian law enforcement agencies, including exotic 'non-lethal'
weapons."
The 4\94 SCIENTIFIC AMERICAN reported: "Federal researchers 
are now investigating a broad array of non-lethal devices
including...LOW-FREQUENCY 'INFRASOUND' GENERATORS POWERFUL ENOUGH TO
TRIGGER NAUSEA OR DIARRHEA,...electronics-disrupting pulses of
electromagnetic radiation..and biological agents that can chew up crops."
To help promote the U.N. global dictatorship, Soviet KGB scientist have
recently been working at various U.S. advanced weapons facilities, such
as Lawrence Liverpool and Los Alamos Laboratories. In November, 1993, a
three day top-secret non-lethal weapons conference took place in the
Applied Physics Laboratory at Johns Hopkins University in Maryland. The
meeting was attended by Attorney General Janet Reno, numerous scientist,
military weapons experts, intelligence officials from state and local
police departments. The main purposes of the meeting was to prepare
leading law enforcement officials for the use of psychotronic
mind-control weapons.
Amongst the subjects covered at the conference were "RADIO-FREQUENCY
WEAPONS, HIGH POWERED MICROWAVE TECHNOLOGY, ACOUSTIC TECHNOLOGY" (used to
transmit subliminal voices into a victims head), VOICE SYNTHESIS, and
APPLICATION OF EXTREME FREQUENCY ELECTROMAGNETIC FIELDS TO NON-LETHAL
WEAPONS." Col. John B. Alexander, Program Manager for Non-Lethal
(psychotronic) Defense, Los Alamos National Laboratory, served as
conference chairman.
The 8\22\94 NEWSWEEK MAGAZINE reported on a secret Arlington, Virginia

(New World Order & ELF Psychotronic Tyranny by C. B. Baker)
===========================================
Such kind of crime will be mostly induced on young people because 
young people will easily be misled to enjoy the sex dreams and
ejaculation.
However, such kinds of man-made sex dreams and ejaculations would be
induced frequently to yound victims in order to waste their enery.
Furthermore, the operators wil use the chronal gun or
infrasound to weak the young victim' kidney.
After using above method, the operators can esaily weaken the young 
people's sex abilities. Some young victims will be even driven to mad, 
if these young victims cannot stop the man-made ejaculation everyday. 
The operators will also use the chronal gun to injure the young 
victims' brain or memories to induce the stupid yound students.
This way, the operators can also interfere with the young people's 
normal lives while they are still learning in school. 
The mind control operators are currently enjoying the above
law's privileges to manipulate people's lives.
The mopst evil is that the operators judge eveyone or everything 
according to their own will but not according to the law.
The operators are the judge, jury, executioner while they use the
invisible wave weapon on our people. They are over authorized , work
secretly and have become the most powerful group in the socirety.
If our President or Congress members don't stop these operators' 
crimes right now, they will not be stoped by anyone.
These career officers and operators will become the real controllers 
of people and haver more power than anyone else because they are really
controlling people's lives.

  secretly (die as if natural cause).  
  The mind (machine) control system is the national security system of 
  Taiwan from late of 1970s and should be the same in US or lots free 
  countries (In Taiwan, the mind machine is translated as "Psychological

  Accusing other as insane without evidence is the "trademark" of mind
  control organization.
  (If any law enforcement officer declare anyone as "insane" and 
   the social security department do not put these individual in the 
   welfare program as diable person, then it only represent a kind of
   political suppression or false accusation to discredit someone.
   That' because the local law enforcement is the basic unit of mind
   control)

The rotational slowdown is caused by tidal friction between the Earth and

360-day year?  It's the _rotation_ of the Earth that's slowing down, not

I suspect on this point there is a fair amount of agreement between us
that may not be obvious.  Please re-read what I meant by "why".  "Why"
and "how" often can be (and are) used interchangeably.  Many
physicists explain in lectures, comments and books reasons "why" in
terms of equations or physical principles.  For example one might say,
"An electron/positron annihilation produces two photons instead of one
because that is necessary to conserve both energy and momentum."  You
gave another example, that of gravity being due to spacetime curvature.
Some people will say this is "how," some will say it is "why" and most
people will say both "why" and "how" at different times depending on
the context of the conversation and what word comes to mind at the
moment.  I would be very surprised if you too don't often respond to a
"why" question with an explanation from a theory or principle that
involves no theology or philosophy.
Unfortunately, definition of terms is very important, and failure to
have a common understanding of the meaning of key words causes a
great deal of misunderstanding and wasted time.  In your response,
you appear to associate "why" with "intent by God or Nature" but I
associate "why" with the cause behind an observed effect.  We are
probably talking past each other.
For the sake of future understanding, I do not think that physics
can explain God or any intent by God, nor should it try to do so.
Physics should restrict its inquiry into the "why" of nature to the
realms of directly or indirectly observable physical phenomena and
its physical causes.  And fundamental postulates whose reasons "why"
are unknowable (by physics at least) must unavoidably underlie the
entire framework of physical theory because there is no physically
knowable, fundamental reason why physical reality must exist at all.
(I would call this statement a fundamental postulate.  Does Knowability
Postulate have a nice sound to it?)

This is a clever trick in your argument:  take my statement and make it
appear more extreme than it is in order to refute it more easily.  Nice
try. :-)
Your key word here is "ultimate".  With that I definitely agree, as you
can see (some duplication of my previous post because you snipped it in
your reply):
   I believe you are entirely correct in your statement that at some
   level we will arrive at a point where we cannot make any further
   progress in understanding "why" and must accept that "that is the
   way things are."  At the very least, that will come when the most
   fundamental postulates are stated.
Knowing when we have reached the most fundamental postulates, and
therefore when we can stop asking "why?" is difficult.  Is it
knowable when we have reached this point?  This is a very relevant
question that has no simple answer.  I have some ideas on the
subject and am sure others do as well, but would prefer to leave
the topic for another time because it is quite involved.
Removing the word "ultimate" from your reply, it appears we agree in
principle.  Any disagreement is likely to be to what extent we can
(or should) try to understand the "why" (underlying cause or mechanism
in my definition of terms) behind what we observe.

Your key word here is "need."  This is a statement of your own belief
about how far physics should go in searching out answers, but is a
vague one since you don't elaborate on how far physics should go.  If
you had used "does" instead of "need" it would seem we are in complete
agreement, since then it would be a statement about the current state
of physics rather than the way physics can be in the future.  If you
will elaborate on how far you think physics should go in searching out
the underlying causes/mechanisms for observed phenomena it probably
will help me better understand your view.

Again, I think you are stating current limitations of physical
understanding and making an unfounded leap of logic to a statement
about what is possible.  A statement about what is possible is
necessarily a postulate, and postulates don't logically follow from
anything else; they are starting points in a chain of reasoning.
Continuing...  If by a more satisfying description you mean a more
complete theory, I would probably agree.  But I think a reasonably
complete theory also explains the "why" behind the phemomena it
describes; I will elaborate on this in a moment.

Let us take another example:  Why does the pressure of a gas increase as
as the temperature increases?  To one who knows nothing about kinematics
or the atomic nature of matter, this could very well constitute a
mystery.  Such a person could hypothesize that some magical, unknown
process transforms heat into more gas.  If no method were known to test
such a hypothesis it could become a fundamental postulate in that
person's theoretical framework.  But the "why" can be intuitively
understood once a person becomes familiar with kinematics, the the
atomic constitution of gases, kinematics and so on.  One can even see
the reason (i.e., intuitiveness) for using statistical models to
describe gas behavior, even though one knows the gas is composed of
discrete atoms rather than some magical substance that behaves
probabilistically.  In other words, the mystery came from a failure
to understand the underlying causes rather than any inherent 
unknowability of the "why" behind the process.
I can extend this analogy to quantum theory.  The probabilistic nature
of quantum mechanics may very well be a macroscopic manifestation of
some understandable process that occurs at a lower level, and our
failure to recognize it as such may indicate a gap in our
understanding rather than the fundamentality of quantum mechanical
postulates.  Similarly, relativity and electromagnetics could be
macroscopic descriptions of underlying, yet understandable processes.
If true, what now is mysterious and unintuitive could become very
clear and intuitive once we know more, and these theories would be
derivable from even more fundamental theories.
This seems to get at the core of the discussion.  If one is convinced
a postulate is fundamental, one sees no point in trying to understand
the "why" behind the postulate.  If one entertains the possibility
that the postulate may not be fundamental, then one sees that pursuing
the "why" may lead to a breakthrough in scientific understanding that
clears up a lot of mystery and opens new areas of inquiry.  In truth,
we don't presently know (and perhaps never will) whether the postulates
that underlie relativity and QM theories, for example, are fundamental.
Currently I see no good reason for believing they are because I have
heard no compelling argument for their fundamentality.  Perhaps you
have?
> After all, what is intuition but our summed

I don't think intuition needs to be restricted to everyday phenomena.
At the least it includes a combination of conformity to one's
conceptual framework (everyday phenomena is a subset of this) as well
as understandable derivations or extrapolations from that framework.

As you seem to agree, we can't "require" anything that is outside our
control, and certainly the laws of nature fall into that category...
I think we can require a physical theory to be consistent and
derivable from postulates and more fundamental theories, but I don't
think we can require anything for the fundamental postulates beyond:
   (a) Fundamental postulates must exist,
   (b) the postulates are orthogonal (not contradictory or overlapping),
   (c) the theories that descend from them have been tested as well as
       currently possible and appear to represent observation acurately,
       and
   (d) the postulates appear to be truly fundamental.
This is a tall order, especially determining that the postulates appear
to be truly fundamental.  As mentioned earlier, I see the question of
knowing when to stop looking for something more fundamental as an
involved but interesting subject that would make a good topic for
another time.
The attainability of an ultimate theoretical model is another good
topic for another time.  It seems this really boils down to whether
or not we can figure out what the truly fundamental postulates are.
From those, a consistent and complete model can come.  I believe the
fundamental postulates will be fairly simple, probably describing basic
physical properties that are not "wierd" and a single source of physical
activity/energy that also is not "wierd;" hence the ultimate, complete
theory would indeed be intuitive.  I know this does not seem to be the
case at the present stage of physical understanding.  It is merely my
personal opinion that may change over time.
