Two mirrors do not a retroreflector make.  Also, if you use two
second-surface mirrors at a right angle, you can't see anything right at
the center, so you would miss the phenomenon I am talking about.

If the retroreflector is wider than the distance between your eyes and is
centered between your eyes, you can see the opposite eye with each eye
looking straight ahead.  But the image of each eye will be visible to
itself in the center of the rr, and this applies to large and small rr's.

Who said that it had to be constant or universal? ;-)
Here-and-now, it's pretty stable (by definition), but if G is a
measure of background mass-density once obvious local variations in
mass-density have been cancelled out (i.e. G as a variable, changing
value over cosmological timescales), then we'd hardly expect to see it
change perceptibly from year to year.
Unless we looked at distant matter, and expected the signals to have a
redshift increasing with distance (decreasing over time) due to the
equivalent of a gravitational gradient between "then" and "now". 
-
But gravitational-domain Hubble shift is another story...  
-
>: Why is the inertial mass 
>: equal to the gravitational mass?
-
If you model inertia as a property that depends on the existence of
background mass, then a local increase in mass-density results in a
local increase in inertia (gravitational redshift). 
Then, an imbalance in mass-distribution results in an imbalance in the
inertia of a test-particle, so that it feels "more" inertia towards
the local region of higher density. It's inertial path deviates
towards this region, and - bingo - you've reinvented gravity as the
effect of inertia. 
-
After that, equivalence isn't particularly surprising
-
Different physicists seem to have different opinions as to how far GR
goes down this route. This is how a fully Mach-compliant theory should
behave, but the current implementation of GR is allegedly not quite
Mach-compliant...

-
BTW, Have you tried modelling inertial mass as a radiation pressure
effect?
-
If you take a thermos flask full of light, the light contributes to
the flask's inertia. Try to push the flask away, and the internal
radiation piles up at your end of the flask and the concentration of
light at the pushed end of the flask presses back against your hand.
It's a transient effect, because contact with the accelerated
flask-end brings the light (protesting) into the new flask frame, and
the thing reaches equilibrium /very/ quickly. 
After that, if you try to take the motion away again by grabbing the
flask, the light then piles up again at the front end, resisting your
applied deceleration. 
-
The exact amount of resistance depends on your assumptions about the
way that light propagates, as this in turn affects our choice of
equations for the way that the length of a moving flask is seen to
change. The relationship between the wavelength of captive light and
the dimensions of the flask that contains it must be the same for all
observers (think of a standing wave), so the observed energy of the
captive light (and therefore its mass) is inversely proportional to
the observed length of the flask along the direction of travel.
If the flask is seen to contract, then the wavelength of the captive
light must be "seen" to shorten by the same amount, and must be
observed to increase in energy by the same ratio (E=h/lambda).
-
The general rule is that the observed length-change is exactly
proportional to the frequency-change seen in light emitted by the
object, so if we assumed that the simple Doppler shift law f'/f =
(c-v)/c was correct, then the overall additional resistance to applied
force caused by the relative velocity of the flask wrt the observer
(who is also applying the force) would be given by 
	m'/m = (c-v)(c+v)/c^2
	m'/m = 1 - ( v^2/c^2 )
, over the round trip.  
-
Alternatively, you can use the SR shift equation and get precisely the
same round-trip relationship.
-
Both formulae generate an averaged root-product effect of 
	m'/m = root[1 - v^2/c^2]
for a single idealised frame transition.
-
If you believed in a "non-flat" propagation model then the effect of
trying to artificially "flatten" the coordinate system by
superimposing the forward and backward shifts together and then
rooting the result, to create an (anisotropic) Cartesian coordinate
system with a rather more polite set of axes, would be to reproduce
Einstein's special theory. Hiding the remaining "curvature" attributes
would then give you the Einstein clock-synch method, the SR
velocity-addition formula, and so on.

Pick whichever version you like best.

Once upon a time many objects have crashed into Mars. The pictures sent
back by the various orbiters show many many craters, which is usually the
result of an object hitting a planet.

No, you seem to misunderstand how these collisions work; many of these
collisions will have hit Mars at a velocity beyond its escape velocity.
They didn't "spiral in;" they just came along at several km/sec and
hit.

Also, although I haven't checked the literature (*) to see if it is the
case, an asteroid hitting at less than escape velocity might still create
circumstances under which a rock might reach escape velocity. There is
more than enough momentum _and_ energy in an impacting asteroid to put a
few measely rocks at escape velocity: the details of whether or not it
actually happens, I think, depend on the speed of sound in the various
projectiles (rocks and asteroids). AFAIK, though, most scenarios aren't
dependent on these mechanisms. There are lots of things that have hit
Mars (and Earth) at beyond escape velocity. There are even films of it.
(For instance, the Lost City meteorite).

I think the answer to both of your questions right there is _yes_.
BUT:

There were articles and papers in the open scientific literature
about how Mars rocks might wind up on Earth long before someone said
they might have life.
Frank's in the business, he can probably quote you chapter and verse.
So it's not like I'd be doing any public service besides saving someone

Science is not digital, but analog.  Some science is very good at 
describing the world and predicting its future state.  Other sciences
are not very good.  By most any measure the science of psychology 
when used to describe and predict the behavior of human beings is
not very good.  It is so bad that it fails my "good enough to 
pay attention to" test.  Psychology is now where astronomy was 
before the invention of the telescope.  You should take its descriptions
of human beings and their mental states with a chunck of salt.  You 
should take its predictions of human behavior with a crystal about 
ten times as large.
This is where _The Bell Curve_ fails.  It depends on psychology.
Let's take the intelligence test as an example.  Let's consider
human beings to be fractals (2 dimensional).  Now a psychologist
comes along and develops a test to classify all fractals.  Since
he has no idea what a human being (oops! I mean a fractal) is,
he develops an arbary test based on his little understanding.
He notes fractal outcomes in life and devises a test that 
allows a thumbnail prediction of those outcomes.  His test
produces a number which he calls fractal dimension.  Most 
human fractals have a dimension of about 100.  It is better
to have a higher fractal dimension than a lower one.  Higher
fractal dimension correlates well with success in life since
the test was developed based on outcomes.
What the psychologist has failed to do, however, is justify
the use of the phrase "fractal dimension".  So we find a
psychologist and ask him, "What is a fractal?"  He doesn't
know, but can give us a treatise on the subject.  We decide
after reading the treatise, that he really does not know 
what he is talking about.  We are then at a loss as to how
he could ever even hope to measure the dimension of a fractal.
Even if he came up with a test, we would be forced to ask
ourselves where the theory is that assures us that all
fractals have a dimension.  Even if this were true, we are
still left with the fact that highly different fractals
can have the same dimension and that we STILL don't know
what there is about a fractal that makes it succeed in
life.  We do have a correlation, however.
You can pay attention to this type of data if you want
to.  But I would rather let someone read the bumps on 
my head.

There is a theory that a planet existed between Mars and Jupiter. This
planet exploded and pieces of it went everywhere and the larger pieces
of it became asteroids and comets. Pieces of the exploded planet could
easily of fallen to Earth. It may be the Mars rocks are actually
pieces of an exploded planet. For more info on the exploded planet
theory see:

Unfortunately, you have said nothing in defense of Creation at all. 
Basically, to evolutionists, what you have stated is almost delusional,
as if you are stomping your feet on the ground in a tantrum and shouting
"There is a God .. there is there is I know it!"
As strongly as you feel, there is a better way to approach the subject.
You see .. to us, your religion is just one of the many religions that
have come about throughout the years.  To us, it is the same as ancient
Greek, or Egyptian mythology.  Your quoting biblical text is very
similar to quoting accounts of Homer's "The Odyssey".  
Let's talk on common ground so we can understand each other.

OK, let's assume the object that smashed into Mars was a comet, or
something similar.  The object will have had a high velocity of its
own before hitting Mars.  It didn't have to just fall onto the Martian
surface, it could have been travelling at a high rate of speed and
just run into Mars.  This type of object could easily have passed
nearby to Mars without spiralling into Mars' gravity field.
Also, the object will transfer a great deal of energy to Mars.  This
energy may not be able to free the entire object from Mars' gravity,
but it can transfer enough energy to a small Martian rock to allow the
rock to leave Mars' gravity.
I'm not sure how the scientists decide that a rock found on earth is
actually from Mars, perhaps someone familiar with this process can
provide more detail.

I'm really surprised at you people.  Where is your skepticism.  "...basic
(and proven) theories of evolution..."  My, My!  Your education is really

Subject: Re: Einstein's Thoughts 4
From: Jack Sarfatti
Date: Mon, 06 Jan 1997 19:56:36 -0800
Thus, Einstein attacks action-at-a-distance with: “If one accepts the
concepts of space (including geometry) and time without critical doubts,
then there exists no reason to object to the idea of action at a
distance, even though such a concept is unsuited to the ideas one forms
on the basis of the raw experience of of daily life.”
Einstein remarks that the requirement that “forces depend only on the
coordinates (and not, for example on their derivatives with respect to
time) ... is not very natural...” Phenomenological friction forces with
the irreversible arrow of time depend on the first time derivative. Also
look at the force of radiation reaction.
Einstein adds a second argument against the kind of intensity-dependent
form-independent classical action at a distance as it is found in
Newton’s law of gravitational force which practically speaking is very
useful and accurate for travel between the planets, for airplanes,
ships, boats, cars, machinery of all kinds etc.
“Within the framework of [Newton’s] theory alone it is entirely
arbitrary that the forces of gravitation (and electricity), which come
from one point, are governed by the potential function 1/r ... it has
long been known tht this function is the spherically symmetric solution
of the simplest (rotation-invariant) differential equation Laplacian of
the potential = 0; it would therefore not be far-fetched to regard this
as a clue that this function was to be considered as resulting from a
spatial law, an approach that would have eliminated the arbitrariness in
the force law. This is really the first insight that suggests a turning
away from the theory of action at a distance, a development that -
prepared by Faraday, Maxwell and Hertz-- really begins only later in
response to the external pressure of experimental data.”
Note here that there are three really different ideas of action at a
distance -- the classical version,  the quantum version, and the
post-quantum version. Einstein above, and also Wheeler and Feynman in
their classical delayed action at a distance both to the future and to
the past light cones, are talking about classical form-independent but
intensity-dependent classical action at a distance. In contrast, Bohm is
talking about quantum form-dependent but intensity-independent action at
a distance. Eberhard’s theorem asserts that conservation of quantum
probability current densities in configuration space precludes the use
of quantum action at a distance, nonlocal in ordinary 3D space and time
as a direct communication channel. In contrast, post-quantum action at a
distance informed by a direct back-action from the rocklike classical
beable to its attached thoughtlike quantum pilot-wave, violates
Eberhard’s theorem because the quantum currents are no longer conserved
in configuration space. That is, the quantum analog to the classical
Liouville theorem in classical statistical mechanics is violated.
Indeed, this post-quantum friction provides the arrow of time and is the
dynamo of creative thought driving the advance of civilization.

There certainly were, and nobody on earth has the tubes for them.  The 
tubes were probably as nifty as tubes ever got: they had extra 
acceleration electrodes and did indeed have a plate voltage of 13.8 volts 
or so.  Getting rid of that vibrator made everyone happy for a while.  
Now, of course, every auto stereo amplifier has a dc-dc converter.  
  The output used a big old germanium transistor that worked through an 
output transformer.  This was a pretty bulletproof arrangement.  The 
reason for the hybrid construction was, I think, that high-frequency 
transistors were difficult to manufacture for a while.  So they used 
tubes for the rf and if stages, and the big transistor to run the 
speaker.

hi all,
a few years ago i saw an amazing demo of "gyroscopic force".
this guy had a 30kg flywheel attached to an axle that he held
in two hands.  another bloke came in and spun the wheel up to
3000rpm with a modified electric drill.  the first bloke then
began to turn slowly on the spot and then dropped one hand from
the axle.  he then waved this 30kg weight in slow circles over 
his head using one hand and no effort at all...  while he kept
the thing moving it was effectively weightless (or that's what
he said anyway!!).
i still don't really get how this demo worked - was it for
real??  i have often wondered why it is not possible to put
a number of gyroscopes at the end of the spokes of a big wheel
and have it float off into the distance.  does anyone know 
what the problem is??

Good try. Next explain to us how your parents told you an ethical truth

Clearly the observation of our world rules out the existence of a being

1. All Powerful.
2. All Loving.
3. All Knowing.
Next you decide to solve the contradiction by removing attribute

So basically, in strawman form, what your unification theory says is:

     2. not all the stuff is the same
     3. the stuff does some things
I'm not terribly impressed by your summary.

does it just describe things in handwaving terms that can be

How does the study show that astrology has any answer? Should and did are

I wouldn't even say that much.  The data is a pretty honest data.  As 
for conclusions, yeah, one certainly cannot state that the data is 
sufficient to prove them.  To say that they were disproved or rejected 
(other than on non scientific grounds) though, is false.

Definitely.  Can hardly be avoided, given human nature.  That's why, 
when analyzing any work, there are two separate questions one should 
ask:
1)  Is the data itself collected and reported honestly (mind you, that 
even if it is, that still doesn't mean that it is meaningful).
2)  Does the data support the conclusions.
In the case of "The Bell Curve" I would say that the answer to (1) is 
yes.  As for (2) an honest answer is "not enough information for a 
reliable conclusion".  However, the thesis brought in the book cannot 
be dismissed as a posible hypothesis.
Any policy must be based on reality, not wishful

Doesn't matter.  What would cause it to bulge out more than usual if not

If the tube has a leak, the pressure would go up when you first squeeze it,
then go back down as the air escapes.
I can't think of a simple way the pressure would initially go down--seems 
the thing would have to be unstable to begin with.  LeChatelier's principle 
and all that.  You'd have to cheat somehow.  Like use a fast-acting sensor/

In the late 50's the Louisville, Ky. Board of Education instituted a few closed 
circuit TV classes, to try and place the best teachers in front of more 
students. My favorite Jr. High School science teacher was selected as one of the 
best. I was saddened to see how his best trait, interpersonal interaction with 
students, was stiffled by the remoteness imposed by the camera. It was difficult 
to feel the excitement he could infect a class with when he was in that little 
box. It was frustrating not to be able to raise my hand and ask him directly for 
a clarification..., to spark that ad lib interplay which always led to fresh 
modes of explanation, and made the student feel part of the learning process, 
not just a spectator. 
I do see a roll for TV education, but a mass voluntary audience is not likely to 
tune in to a classroom like show. Nova, Cosmos, Nature, and their like, do a 
good job of educating, but they hide the experience inside a sense of 
entertainment. The degree to which learning is achieved is not easily measured, 
so good teacher in a controled classroom environment, with high standards set, 
is the best proven way to increase student performance.
At least that's what I think,

Time is orthogonal to the three spatial coordinates.  This implies
time may vary without the any of the three spatial coordinates
changing. And vice versa.  This implies also that if we fail
to record the time of an event this information cannot
(in general) be derived from the spatial information of
the event under observation.  In order to distinctly specify
an event in this particular universe we require FOUR
orthogonal pieces of information.  One of them is the
time of the event.
Time is abstract in the sense that it is measured
somewhat differently to the other three spatial coordinates.
But the time coordinate is (is general) equally important as
the three spatial coordinates when making observations.
If time were not orthogonal (and independent of) the
three spatial coordinates then bus timetables would
only have departure and destination locations.
Adding the times of departure and arrival would be
pointless.

Again, what magnetic pulse? Do you understand enough about electricity and
magnetism to understand how a pulse like that might behave, where it might
come from, and how you might measure it? 
How do you know the whales don't just greet the sun or something? They

Okay, somebody tell me why this wouldn't work.  I want a better answer 
than "shut up", so I figured I'd come here.
I wanna know why you couldn't use some of the stuff hinted at by the EPR 
thought experiment to make an instantaneous communicator.  Here's how I
understand the EPR experiment:
	Take two particles that are linked (perhaps they were paired 
electrons in a single orbital.  Their spins are opposite).  Then 
separate them.  You'll have two electrons, each with a .5 probability of
+1/2 spin, and .5 P of -1/2.  Take them to opposite sides of the globe,
and measure one of them.  Say you find that it's +.  You've taken it
from .5 P to 1P.  You changed it.  That's okay, cuz you measured it.
However, you also know that the other electron (on the other side of 
the world, or heck, on another planet!) is -.  You've changed it from 
.5 to 1 without doing anything to it!
Okay, we'll pretend that I understood that experiment correctly.  Here's
where I get really crazy.  Isn't there some stuff that behaves 
differently depending on whether or not you've measured it?  Maybe an
electron with a .5 probability responds to a magnetic field differently
than one with 1P.  Something like that.  If _all_ of that's true (fat
chance), could you build some sort of device where you could take one
of a pair of linked particles and figure out whether the other one is
being measured?
Awfully far-fetched, I know.  But what do you expect, I'm just a kid.
If (I noticed I used that word an awful lot) you can measure whether 
your partner on the moon is measuring some property of a particle, then
you can repeat things like that to form binary communication.  1 when
the particle is being measured, 0 when it's not.
Okay, so just someone explain why that won't work.  Thank you.
Seeya :)

I think so :-)
Depends on your mileage of course.  Are you fluent in quantum field
theory ?   (not the pictures, but the calculations, how to treat the
divergencies - although I think that part actually gets easier in
string theory - how to tackle the apparent gauge dependencies ... )
I, for one, am not really.  I know the basics and can, with some difficulty,
follow certain calculations, but I'm far from being an expert on it, so
I don't even attempt at string theory.
Don't forget that there is usually a separation of 3-4 years of full-time
studying between the level of mathematical sophistication needed to understand
popular works and professional literature.
cheers,
Patrick.

Perhaps the n-adics the composite adics such as 6-adics , 10-adics,
14-adics ad infinitum are not the inside of a sphere. Perhaps they are
the outside of the sphere surface that is the 2-adics. Thereby, the
prime adic forms a Riemannian sphere surface and the associated
composite adics of that particular prime adic forms the outer regions
of that sphere surface caused by that prime-adic.
  Then, the Doubly Infinites of the 2-adics forms the disc or inside of
the 2-adic sphere. 
   The 2-adics forms a Riemannian sphere surface, the 2-adic composite
associated adics of 6-adics etc forms the outer regions of that 2-adic
surface and is still Riemannian geometry.
   The 2-adics Doubly Infinite where the leftward string is 2-adics
forms a disc inside the 2-adic Riemannian sphere and is Lobachevskian
geometry.

Molybdenum is an essential trace element in soils and in agricultural
fertilizers. Molybdenum atoms have been found to perform key functions
in enzymes (oxidases and reductases, with particular interest being
directed toward its role in nitrogenase, which is employed by bacteria
in legumes to convert inert nitrogen (N2) of the air into biologically
useful ammonia (NH3).
   Molybdenum is widely distributed in the Earth's crust at a
concentration of 1.5 parts per million by weight in the lithosphere and
about 10 parts per billion in the sea. 
   CHEMISTRY. Although Molybdenum is closer to chromium in atomic
weight and atomic number, its chemical behavior is usually very similar
to that of tungsten, which has nearly the same atomic radius. (This is
due to the so-called lanthanide contraction in which atomic radii
decrease...
   Molybdenum atoms contain six valence electrons ...  Molybdenum forms
a very large number of compounds with oxygen. Low-valent molybdenum
[for example, Mo(CO)6 and Mo2, Mo3, and Mo6 clusters] has a very rich
organometallic chemistry, including clusters that are being studied as
models for molybdenum metal surfaces that catalyze organic reactions
employed in industrial syntheses and oil refining.
   SUPERCONDUCTORS: Mo6S8 clusters.
... These materials, which form so-called Chevrel phases having
superconducting properties, ...
   ORGANOMETALLIC COMPOUNDS. Mo(CO)6 is a stable octahedral complex of
Mo(O). . . It is the starting material used in the production of a
large variety of organometallic molybdenum compounds containing single,
double and triple Mo-C bonds ... including mixed metal complexes.
   Molybdenum in low oxidation states forms very stable bonds with
p-acceptor ligands such as CO
   BIOLOGICAL SYSTEMS. The versatility of molybdenum in accommodating a
large variety of structures, oxidation states, and polynuclear
complexes makes it a prime candidate for the active site in enzymatic
processes involving molybdoproteins in enzymes and cofactors. During
the reduction of N2 to ammonia by nitrogen-fixing organisms, protons
are reduced to H2, and adenosinetriphosphate (ATP) is hydrolyzed to
adenosinediphosphate (ADP); N2 must bind to an active site and be a
receptor for the transfer of  both electrons and protons. Each of these
functions can be performed or facilitated by molybdenum atoms or ions
in other systems, making this element a prime target for research on
nitrogen fixation. A list of enzymes that contain molybdenum, their
properties, and functions is given in Table 2.
   Figure 4 shows the structure of the iron-molybdenum-sulfur cluster
found in a protein that serves as an Fe-Mo cofactor in several enzymes.
The role of molybdenum in nitrogenase has been of great interest.

The geometry of Molybdenum, and Lithium are such that bioworld room

 Conglomeration = set. Set of all prime-adics {2-adics, 3-adics, ....}
 Instead of conglomeration, I am going to define a branch of the
tangent function, taking a branch of the tangent function that curve is
the 2-adics, and the next branch will be the 3-adics, another the
5-adics and so on. All of the points of the 2-adic branch of the
tangent function will be 2-adic numbers.  But this is not the big deal
in this program. Now in this graph of the tangent function, each branch
is a function , but now consider all the points in that specific branch
itself, then all of those points do not make a function. Correspond all
of those points with the prime-associated-n-adic. Here are some prime
associated n adics for the 2-adics 6-adics, 10-adics, 14-adics etc.
   Why do this program? Answer is threefold. To connect adics with
geometry. And another reason is to find, or discover what the
composite-adics are. Third reason: in a way, algebraic structures
fields, rings, groups should be connected with simply a function and a
graph.
   The function, for example , one branch of the tangent function is a
algebraic Field.  What are the other parts of the graph (the points
underneath the tangent function as an algebraic structure. That is 2nd
dimensional but in third dimension (only existing true dimension) the
surface of a sphere would be the 2-adics and all of its composite
2-adic associates would form the inside of this 2-adic sphere surface.

OK, I just had to respond to this!   I am a film director.  I'm
constantly looking for stuff like this to throw into a film here and
there -- facts that are "blurred" by the  frequent need to present
events in a dramatic setting.
So.......what really does happen when that radio or hair drier falls
in?  The notes here clearly indicate that it won't cause death.  Will
it cause anything?  Tingling?  A hearty zap?  Nothing?  Would love to
know the answers to add this to my notes.
Now, (you know this was coming) to explain (not necessarily defend)
the incorrect portrayal of various "facts" in film and television.  As
directors, we're always looking for a path to an audience's emotional
core.  Unfortunately, the quickest way to those places is to rely on
the fears that were imposed on us as we were growing up.  These are
implanted in our brains as survival tools.  Whether the facts behind
the fear are valid or not, it's still a fear, which is an emotion,
which gets you right where I want you. 
 You may notice, however, that the weaker the basic story in a film,
the more it will rely on these "parlor tricks" to keep the majority of
the audience interested.  
So, what would really happen?

 One should be able to take a graph, a function and point to this graph
and point out various algebraic structures in the graph itself. Take
for example a  linear function. Then the line of that function
represents a Field. Then, some of the rest of the graph is a Ring,
another portion is a Group etc.
  What I am looking for is what is the most Complex and Complicated yet
meaningful Algebraic structure when I amass all of the prime-adics and
composite-adics together. Note the word meaningful. I suppose it is a
Geometry. That the highest algebraic structure is a geometry and we
have only three of those-- Riemannian, Lobachevskian, and Euclidean. A
Field, a Ring, a Group, etc all of these algebraic structures are parts
of a geometry.
   I need to know what is the highest meaningful algebraic geometry
when I pile all the adic forms together, both prime and composite
adics. I think the answer is that it forms a geometry.
   Now, let us look at Euclidean geometry since we know it well. Do the
points as Reals+i+j  do those points form a Field? Can some of them
form a Ring? Can some of them form a Group? But the highest algebraic
structure of Euclidean 3-space is Euclidean geometry itself.
