I want to know what is the theory that explains what causes atoms
to stick together in a solid. If the perimeter of an atom has a

at least, if the charge of the nucleus balances the charge of the
electrons).
Thanks!

Unfortunately, this is already wrong: the electrons are *not* "in
orbit around". Don't picture them as little marbles flying around the
nucleus like planets around the sun. A better picture (still not the
truth, only a visualization!) is that the electrons form "charge
clouds" around the nuclei.

It's much easier to first look at a simple molecule instead of going
to a solid at once. Let's look at the hydrogen molecule, H_2, i.e. a
molecule consisting of two protons and two electrons. Now picture the
"charge cloud" of the electrons to be concentrated between the two
protons (see e.g. fig. 6-2 at
<http://www.chemistry.mcmaster.ca/esam/Chapter_6/intro.html>)
Both protons are attracted to this charge cloud, but they also repel
each other. There is one distance between the protons where these two
forces exactly cancel out each other. Then you have the stable
configuration of the molecule.
Does this help?

See: http://www.google.com/search?q=atomic+structure+of+solids
I've heard of it being referred to as a cloud. But if an electron was
moving fast enough, and its distance to the nucleus wasn't constant
(I assume there is some degree of wobbling and ellipticality in the
orbit) then it would be like a cloud. I don't see what distinction is
being made when they describe it as a cloud.

I wouldn't call a motion which makes it from the outside look as if
there were a cloud an "orbit".
But it isn't this way. The electron doesn't move around and is at
this place at this time and at another place later.

Molecular orbital theory in isolated molecules, band theory in
solids. The overall free eenrgy of an atomic aggregate is a summation
of many factors. Any true minimum on the energy hypersurface will be
bound. Atoms are charge-neutral. Na2[Fe(CO)4] (Coleman's reagent)
sits in a bottle nice as you please. What holds together the
[Fe(CO)4](-2) ion? That is iron in a (2-) oxidation state. Rust is
iron(3+).
More to the point, if the conversion of a high energy state to a much
lower energy state requires surmounting a substantial energy barrier,
the high energy state persists. Mountain lakes don't suddenly
disappear into the ocean unless there ia a drainage path.
Tetra-tert-butyltetrahedrane is impossibly strained - way more than a
single bond strength - but there is no low energy path for it to
decompose along. If you kick it hard enough you get
tetra-tert-butylcylobutadiene, another formally non-existent molecule
- that in turn has nowhere to go except back to starting material.
Deforming the sterically crowded moelcules is very energetically
demanding. The jammed peripheral bulk rpevents stuff on the otuside
from getting in.
Worse still is triprismane, C6H6. It looks like it should be benzene
- that is at least 90 kcal/mole lower in energy. If you want
triprismane to crack you must add still another 33 kcal/mole! What
keeps the thing together? The only barrier to rearrangement is a
symmetry mismatch in the respective molecular orbitals, starting
material and product. It's held together by algebra.

Why not? If we could speed up time and watch the planets revolve
around the sun a ridiculous number of times per second, they would
form a cloudlike sphere around the sun. Are you saying that they
would no longer be in orbit around the sun?

So you're saying electrons are stationary? That makes no sense...
Matt Gregory
No, what people are saying is that the electron is not
a little planet.
And you are incorrect about the nature of planetary orbits,
which are pretty much confined to a plane. If you plotted
the position of the earth over a million orbits, you
wouldn't get a cloud which extended through the sun,
above and below the orbital plane, and out beyond the
orbits of the outer planets. At best, you'd see a very
small variation in radius.
But the electron cloud DOES extend beyond a plane,
through the nucleus, and out into space far beyond
the classical Bohr "radius".

The electron does not have a fixed, definite position.
An electron "orbit" is actually a probability distribution,
that distribution is stationary, and any attempt to
pin down an electron position might find it anywhere
in that cloud at any given time.
- Randy
I was thinking way more than a million, I was thinking
the number of orbits that you would get if the earth
moved close to light speed and the universe were shrunk
to the size of an atom. Even if it were confined to a
plane, the plane itself would be all over the place.
That doesn't really affect the point I was trying to
make though. An orbit is an orbit no matter how fast
it goes.

Ok, gotcha. I didn't realize they meant that the cloud
goes all the way to the nucleus.

All this says to me is that they can't determine the exact
path of the electron, or if they could it would be so complex
and yield so much data that they wouldn't be able to do
anything with it, so they resort to probabilities instead.
That still doesn't refute the idea that an electron is moving
around a nucleus in some fashion.

The cloud and its properties look like a bunch of scientific liges.
(Can ye prove me wrong?) The proton and electron are an
electromagnetic planetary sustem, and can't fully be compared to the
gravital sustem, duh. Both charges have classical motions. As for why
the electron doesn't radiate and spiral into the nucleus, as it's
accelerating around the proton, it's because the electron already has.
Note that the ground bound electron spends most of its time /in/ the
nucleus. The round orbitals stay put not because they are
nonclassically forbidden to leave, but because they /do/ radiate, and
the radiation emitted between the charges equals the radiation
absorbed. The extension of the round orbitals is caused by the
illuminating background bringing the electron out of its nuclear sleep,
and the fullness of the orbitals is caused by the background inducing
electromagnetic tidal and proxy forces (They miscall them
pseudoforces.) in the charge-neutral, geometrically-frustrated,
semidegenerate couples. (Everything's polarisable.) They may be
[mis]calling these radiative interactions "zero-point" instead, and
these fluctuations in the ground electron the "Lamb shift".
Bilge? Al? Greg? Sam? I wrote the above a third asleep. It should be
easy to prove me wrong? (Bilge never procured those experiments
showing the s orbital wasn't a time-averaged picture.)

As you can see in the above. What really surround the nucleus
are the electron waves. The electron as particle doesn't
have any continous path. Suppose the sun is the nucleus and
the earth the electron. What would happen is that the
earth would jump from one place to another in space without
a path... that is.. it could be teleporting. Imagine too that
the earth as electron will form a wavelength around the sun.
It is the wavelength that dictates the electron behavior and
its stability from the sun. Imagine the electron wave as 3D
around the nucleus or the earth wave as 3D around the sun.
This is what goes on in the atom. Do not use any classical
example of particle orbiting around a fixed position because
in the quantum world, this doesn't exist because wave and
particle exist at the same time.. or rather.. particles
don't truly exist. It is the field that convey the wave and
particle properties of matter. The field is no ordinary field
too.

The electron is the same as a galactic arm

It extends from center to edge and is

But isn't the 'illuminating background' basically the prevailing
temperature (blackbody radiation)? Isn't the range of the 'illuminating
background'
continuous? Wouldn't the resulting 'orbitals' be continuous
in radius or probable radius?

Wrong. The electron *does not have* an "exact path"! And it can be
*shown* *experimentally* that the *only* way to describe the
behaviour of elementary particles in a sensible way is probabilistically.
What you propose is something like a "hidden variables" theory. And
that has been ruled out experimentally. Read up on "Bell's inequality"
and Aspect's experiments.

No, I'm also not saying that electrons are stationary. Our macroscopic
concepts simply don't apply to them. They do not have a well-defined
position and well-defined velocity at any time. Very loosely speaking,
they are "everywhere at once" and have "ever velocity at once".

Y.Porat
-----------------
Porat. The electron is a point particle. I'll explain.
When you are playing arcade game and you hit the
racing car to the wall. It looks solid isn't it. Does
that mean there are particles in the wall inside the
video game? No. This is also what is reality. All are
fields and waves. The "particles" are just to create
solidity in our frame of reference. This is why the
electron as point particle can have intrinsic properties
such as charge, mass, spin, momentum, etc. They are
not being caused by the particle itself. It is the field
which caused them and the electron as particle is just
a vortex of the field. Do you understand?
For all intent and purposes, our reality is just some
kind of projection. The ancient said everything is maya
or illusions. So we are like inside the arcade game
where programming are inputted inside. Likewise, what
gives all the particles their identities are also programmed.
This is why the electron is a point particle. It's
properties are caused by the field. Just imagine the
quantum vacuum as some kind of screen just like tv screen
where things could be programmed to interact.
Is there a way to reprogram it? Yes. I am slowly grasping
the fact that qi is part of the programming aspect much
like electricity is need to run the program of the arcade
game. Our consciousness can make it interface to this world.
By controlling qi and depending on the level of control, one
can create and uncreate matter and the whole of spacetime.
This may be the explanation why some people can teleport
objects. I have met some who have witnessed materializations
of people. Using the concept of physics, you know how
hard it is to bypass the nuclear binding energies and
get over quarks confinement. So teleporations occurs by
the target reprogramming space/time and initiating
regional phase transitions without temperature modification
(courtesy of the qi field that can reprogram reality).
This is one way to explain the phenomena without breaking
any *normal* laws of physics. This also means that physics
is on the right path. At least scientists are honest. They
know reality are so weird and so they just focus on the
mathematics and just ignore the causal mechanisms with
the words "We don't know why. We can just describe it".
What I desribed here may be the causal mechanisms of
Quantum Mechanics and the rest of physics. What you cranks
are doing trying to model reality as some kind of bolts
and nuts may fail because reality could be just a
projection... which is one of the few possibilities to
explain the bewildering physics of qi.
In any event. Standard Model may be 99.999% true. They
are just projections of a program. What I'm suggesting
is that we can control the program itself given our
development in consciousness (which is a higher mode
of reality and accessible inbetween this SM world and
the higher world or reality).
Can you grasp what I'm saying.. hmm.. maybe one day
when you witness a person just appearing in front of
you as in teleporation. Then you will know by heart
that things are not what they seem. There are much
higher reality to things taught to you by physics.

If the universe only consisted of the sun and the earth and neither
of them ever changed at all, then it would be true that the earth
would orbit in a ring and it would never change. But that's not
how the universe is. There are countless other forces acting on
the earth besides its inertia.

First, inertia is not a force. Second, I really don't know what
collection of forces you imagine which could make the earth reach

Well if the electron absorbed more than it emitted, such as from a
nuclear decay, it would jump away and be free of the proton. If it
emitted more than it absorbed, such as from a nuclear inverse decay, it
would continue deeper toward and into the nucleus, eventually lodging
into a proton with the energetic help of an antineutrino to shield it
from further excitations. When the electron and proton spiral into the
same place in an ideal vacuum, which should also ideally take an
infinite while to radiate away because the moment never decays to
nothing, then any further power one plugs in for an arbitrary
transition is looped shut because the pair are in equilibrium. Outside
of vacuum, the pair assumes a new equilibrium based on the background
temperature, and will fluctuate around the new moment. I wish I could
find any pages along this line of thought, but there's only Larmor
power which doesn't say anything about the absorbance or efficiency of
radiation absorbed by the electron.

Each orbital is already roughly continuous, from the bound
proton-electron potential surface (not hupersurface) to the edge of
space. Nodes classically represent infinite energy surfaces, centred
on fulcra like libration points in orbit but repulsive. The electron
and its ghost twin with imaginary states trace out the wave shapes.
They react to continuum background radiation by extending the orbitals,
and to discrete key radiation by reshaping the orbitals. In an ideal
vacuum (a timeout void), I'd expect the electrons to be at the wave
maxima or potential minima of each orbital. All s orbitals touch down
and become a dot at the nucleus. All p orbitals align (get honed) and
fall linewise tunnelling through the s electrons until they cap the s
electrons in all axes. Most of the higher orbitals will do the same
but cap with greater freedom; their least-momentum suborbitals,
however, become rings and lines and fall that way. The greater orbital
angular momentum of the higher orbitals acts like a guroscope,
stablising the electron from tracing out round shapes. This is why the
higher their trend the thinner their wave bulbs or rings are; instead
of whirling around the nucleus like the s electrons, they bounce and
trend more like springs and planets. Because all atoms have extended
orbitals, the continuum radiation transmitted by the orbitals is
greatly and mostly in fase with that of the detectors, so they are not
found to participate in energetic transitions. The experiments and
theorems disproving hidden variables are invalidated by the fact that
the states of one observable particle are /nonassociative/ thanks to
its wave-mocking twin.

Which would make electron energy levels continuous and closely
related to temperature. Atomic spectra show that not to be

Energy levels /are/ continuous and correlated to temperature and
pressure; though these are already in fase with the detectors' so they
don't show up as sharp, principal, diffuse, fundamental, etc. lines.
As a proof of this, atoms in the solid state have finite compressive
moduli and continue to shrink without bound when cool, until they
become a bunch of neutrons which can also shrink without bound with
added pressure, and the same for quarks. Atoms also shrink when heated
or shot, making them harder to tunnel. These can only happen by
energetic quasiradiative transitions in every orbital.

Extrema of course are not continuous. Domains are. (The right term
would be continual, over continuous, because ultimately I claim
spacetime to be discrete Planckwise.)
