The Planck action constant is independent from any
weak or strong gravitation field. It therefore somehow mirrors the fundamental
difference of physical macro and micro world, (DeH).
(2) The conservation of energy
The conservation principles of energy, linear
momentum, angular momentum, and electric charge are amoung the most fundamental
principles of physics. … The notion „conservation“ as in „conservation of
energy“ is not the same as „invariant“. They are related, …, but they are not
synonymous. The momentum or energy of a system of particles may be conserved
but not necessarily invariant, (NeD) pp. 1, 4.A second fundamental
principle in physics is the least action principle; here physical action
requires a potential difference or a pressure. There is no action just due
to the presence of energy or a potential. (3) Invariant quantities
The invariant quantities in energy conservation laws
are governed by functionals. The simplest model of functionals is a constant.
In a Hilbert space framework such a functional is provided by its norm.
(4) The Noether theorem The probably most fundamental mathematical theorem in
physics is E. Noether‘s theorem. It effects a huge class of conservation laws
governing symmetries of space, time, and „internal“ variables. Noether’s
theorem relates conservation to invariance, and thus to symmetry. This theorem
provides the mathematical foundation of the whole quantum mechanics. However,
the conservation of electric charge emerges from a more abstract symmetry
called „gauge invariance“. (5) An indefinite metric in a Hilbert
space
An indefinite metric in a Hilbert space is one of the
unconventional features of Heisenberg's "Introduction to the Unified Field Theory of Elementary
Particles", (HeW). (6) Manifolds
The terminology of "multiple extended
quantities" was introduced by B. Riemann, synonymly to a
"continuous manifold". The history of manifolds is the attempt to
build a mathematical structure to model the whole (the continuum) and the
particular (the part) to put its combination into
relationship to describe motion, action etc. It is conceptually based on two
essential attributes: "continuity" and "multiple
extension". Based on the concept of a manifold developing a mathematical
framework which symbolically explores the "relationship between the
part and the whole" for the case of the continuum lead to the concepts of
of co-variant derivatives, affine connexion and Lie algebra.
(7) First appearance of manifolds in mathematical
physics
Of course there are several semantical links of the
manifold concept to physics, which could be pursued even in the 19th century.
Riemann had already started to discuss such links on at least two levels. The
final part and culmination of his Habilitations talk gave a sketch how in a
subtle interplay between mathematical arguments and the evaluation of
physical/empirical insights he proposed to come to a refined understanding of
physical space. The essential bridge was an improved understanding of the
microstructure of matter and its binding forces that should be, according to
Riemann, as directly translated into differential geometric structures on
manifolds as possible. But he also left the possibility open for further
consideration that perhaps some time even a discrete structure of matter has to
be taken into account, as it might very well be that the concepts of rigid body
and light ray lose their meaning in the small. Still, so Riemann argued by
reference to astronomical measurements, the acceptance of a Euclidean space
structure was well adapted to the physical knowledge of the time, (ScE6).
(8) Hermann Weyl’s „Purely Infinitesimal
Geometry“
"A general concept, the whole (here the continuum),
has to be presupposed in order to give meaning to an individual determination,
the particular, or the part (here the point). On the other hand, the
whole, the general concept (the continuum) is constituted in a process of
common generation by particulars (the parts).
This conceptual figure came close to those procedures that had been called
„impredicative“ by Russell and Poincaré and that had been blamed as being
responsible for contradictions of the type of Russell’s antinomy“, (ScE6).
(9) (Plemelj’s) double layer potential
J. Plemelj proposed an alternative definition of a
normal derivative, based on Stieltjes integral. It requires less
regularity assumptions than standard definition; the "achieved"
"regularity reduction"is in the same size as a
reduction from a C(1) to a C(0) regularity. Plemelj's concept is proposed
to be applied to ensure physical model requirements modeled by normal
derivatives within a distributional Hilbert space framework, (PlJ).
(10) The problem of an ill-posed problemNSE system
"In
the NSE with the unknowns velocity v(x,t) and the pressure p(x,t) fields the
field p(x,t) can be formally obtained - by operating with "div"
on both sides of the NSE - as a solution of a Neumann problem. From this it is
clear that to describe the values of the pressure at the bounding walls or at
the initial time independently of v, could incompatible with the NSE and,
therefore, could render the problem ill-posed", (GaG).
(11) Exterior space problems in physics
Exterior space problems in physics primarily revolve
around the limitations and inconsistencies between general relativity and
quantum mechanics, particularly when dealing with extreme conditions and the
nature of space-time itself. Key areas include the nature of dark
matter and dark energy, the unification of gravity with other forces, and
the behavior of space-time at the Big Bang and black holes. Additionally, the
concept of quantum gravity and the potential for emergent space-time
are active areas of research, Wikipedia
(12) The Neumann PDE system: an exterior space problem
"In the Navier-Stokes Equation (NSE) system
the field p(x,t) can be formally obtained - by operating with
"div" on both sides of the NSE equation - as the solution of an
exterior space Neumann problem. From this it is clear that to describe the
values of the pressure at the bounding walls or at the initial time
independently of v(x,t), could incompatible with the NSE system and, therefore,
could render the problem ill-posed", (GaG).
(13) The d’Alembert “paradox”
The d’Alembert “paradox” is about the failure of the
Euler equation as a model for fluid-solid interaction as in
incompressible fluids there are no frictional forces.
(14) Current matter and force particles of the universe
„All known particles in the universe can be divided into two groups:
particles of spin ½, which make up the matter in the universe, and particles of
spin 0, 1, and 2, which give rise to forces between matter particles. The
matter particles obey what is called Pauli’s exclusion principle“, (HaS1)
pp. 69/70.
„The neutron is observed to change spontaneously into a proton, an electron,
and a neutrino. This process is so rare that we can often ignore it. Neutron
decay takes on the average some thousand seconds for a free neutron, whereas
within a nucleus the characteristic time between nucleon-nucleon collisions is
only 10 exp(-21) second“, (BeH) p. 29.
„The word „neutrino“ has been used to represent any assumed product of decay
which has half-integer spin, no charge, and neglegible mass. Whether these
particles are all identical with neutrinos of beta-decay is so far
conjecture“, (BeH) p. 32.
„Charge neutrality is one of the fundamental property of plasma, the fourth
state of matter: it is about the shielding of the electric (Coulomb) potential
applied to the plasma. When a probe is inserted into a plasma and positive
(negative) potential is applied, the probe attracts (repulses) electrons and
the plasma tends to shield the electric disturbance“, (MiK).
The conceptual element in superconducting metal models is an electron-phonon
interaction governed by strongly electrostatic Coulomb repulsions accompanied
by an electron-phonon coupling parameter. The related Bardeen-Cooper-Schrieffer
(BCS) theory is governed by a Coulomb pseudopotential, (AnJ).
(15) Dirac‘s single atom-radiation system
Dirac’s single atom-radiation system deals with energy, which is the sum of
three terms: one representing the energy of the atom, a second representating
the electromagnetic energy of the radiation field, and a small term
representing the coupling energy of the atom and the radiation field“,
(FeE).
(16) Ether, perfect plasma and perfect electrodynamic fields
Einstein considered Maxwell’s equations in combination with the requirement
that light moves with a certain velocity as laws of physics.
Lorentz envisioned „various kinds of ether pressures, objects would be
squeezed and therefore shortened", (SuL) pp. 60-62.
Ehrenhaft interpreted his discovery called photophoresis, as „light induces
electric and magnetic charges (poles) upon the particles if they are
illuminated by concentrated light preponderantly shorter wave lengths“, (EhF)
p. 242.
The existence of quantum fluctuations dynamics in a „world“ without a time
arrow and without entropy has been verified by the Casimir and the Lamb shift
effects.
(17) SMEP and gauge invariance
In SMEP (Standard Model of Elementary Particles) symmetry plays a key role.
Conceptually, the SMEP starts with a set of fermions (e.g. the electron in
quantum electrodynamics). If a theory is invariant under transformations by a
symmetry group one obtains a conservation law and quantum numbers. Gauge
symmetries are local symmetries that act differently at each space-time point.
They automatically determine the interaction between particles by introducing
bosons that mediate the interaction. The U(1) symmetry, i.e. the complex unit
circle numbers, (where probability of the wave function is conserved) describes
the electromagnetic interaction with one boson (photon) and one quantum number
(charge Q). The group SU(2) of complex, unitary (2x2) matrices with determinant
1 describes the weak force interaction with 3 bosons W(+), W(-), Z, while the
group SU(3) of complex, unitary matrices describes the strong force
interaction with 8 gluon bosons. This means that each of the observed Nature
„force“ phenomena are related to a specific gauge group. The SMEP does not
provide any explanation where the related elementary „particles“ were built
during the inflation phase of the current big bang story and why their mass
have their specific values.
For gauge symmetries the fundamental equations are symmetric, but e.g., the
ground state wave function breaks the symmetry. When a gauge symmetry is broken
the gauge bosons are able to acquire an effective mass, even though gauge
symmetry does not allow a boson mass in the fundamental equations.
(18) The Higgs effect (or mechanism)
The Higgs effect (or mechanism) builds on an extended from global to local
U(1) transformations symmetry group of the underlying Lagrangian. It
explains the mass of the gauge W- and Z- (weak interaction) bosons of the weak
“nuclear-force”. The Higgs boson is supposed to be a heavy elementary particle
(with non-zero rest mass of about 125 GeV with spin 0). The Higgs field is
supposed to fill the whole universe interacting with each particle, which
“moves” through it by a kind of frictional resistance, i.e. which has kinetic
energy. Therefore, the Higgs effect requires a Higgs field with not vanishing
amplitudes in the ground state.
„The Higgs mechanism helps in two ways. First, gauge fields can acquire mass
by the symmetry breaking. Second, the undesirable Goldstone bosons (which arise
in the symmetry-breaking process) can be usually gauged away”, (BlD) 10.3.
This degeneracy of the physical vacuum (as a result of a “spontaneous”
breakdown of symmetry) permits … nonzero vacuum expectation values (or
“vacuons”), (HiP).
(19) The standard model is not the final theory
„Theoretical physicists are convinced that the standard model is not the
final theory. There are a number of phenomena which find no explanation in the
context of the standard model and must be added in an ad hoc manner. For
example, the Higgs mechanism, th mysterious field which gives mass to all other
particles, does not follow in any sense from the standard model. The apparent
asymmetry between matter and anti-matter is not explained by the standard
model. Neutrino masses do not naturally arise in the context of the standard
model. There is clearly physics, a deeper theory, beyond the standard model“,
(SaR) p. 82.
(20) The London dispersion forces
(Wikipedia): The term "van der Waals force" is used to describe any
dipole-dipole interactions in atom/molecules. Since hydrogen bonds involve
interactions between permanent dipoles, they can be considered as a type of van
der Waals force (and would fall under the category of Keesom interactions). The
strength of van der Waals forces varies, with dipole-dipole interactions
typically being stronger than covalent or ionic bonds. "London
dispersion forces" are a specific type of intermolecular force
present in nonpolar molecules. They are the weakest of all molecular forces.
Molecules like noble gases (e.g., He, Ar), diatomic molecules (e.g., H2), and
nonpolar organic molecules experience these forces.
(21) A sun basically consisting of liquid metallic hydrogen
A gaseous structure of the sun do not allow "white light" blackbody
rays passing from its interior through the observed surface of the sun to
Earth. At the same time there is no direct observation of the presence of
classical concepts pressure & density in the atmosphere of the sun,
which may explain a phase change from gaseous hydrogen to liquid metallic
hydrogen governed by London dispersion forces ((Una4) p. 73.
The fusion process from hydrogen to helium is the energy production process of
the sun. The hydrogen molecules shows only two electrons, however there is an
enormous bounding energy of the electron in a hydrogen molecule, (RoP), (UnA4)
p. 64.
There is no direct observations neither of the pressure nor of the density in
the entire atmosphere of the sun, (UnA4) p. 59.
Ironically, astronomers admit that liquid metallic hydrogen occurs in planets
like Jupiter or Saturn, (UnA4) p. 61, Wikipedia
The minimum volume of a substance on atomic level is determined by the nature
of the electrons not so much by the (far larger) nucleus. ... Metals appear
incompressible, but exposed to an exterior pressure they can reduce their
volume. ... According to de Broglie's wave length formula for a electron such a
volume reduction would lead to a reduction of the wave lengths of all electrons
(i.e. basically the inverse of the mechanical momentum of those electrons) in
the metal, (UnA4) pp. 63/66.
There is an interesting phenomenon when water is subjected to massive pressure:
water close by a nuclear explosion gets black and opaque, (UnA4) pp. 71/72.
(22) Oceans generating microwave background
"Though liquid water has a fleeting structure, it displays an
astonishingly stable network of hydrogen bonds. Thus, even as a liquid, water
possesses a local lattice with short range order. The presence of
hydroxyl and hydrogen bonds within water, indicate that it can simultaneously
maintain two separate energy systems. These can be viewed as two very different
temperatures. The analysis presented uses results from vibrational
spectroscopy, extracting the force constant for the hydrogen bonded dimer. By
idealizing this species as a simple diatomic structure, it is shown that
hydrogen bonds within water should be able to produce thermal spectra in the
far infrared and microwave regions of the electromagnetic spectrum. This simple
analysis reveals that the oceans have a physical mechanism at their disposal,
which is capable of generating the microwave background", (RoP2)
(23) The extraordinarily special Big Bang story
„In order to produce an universe resembling the one in which we live, the
Creator would have to aim for an absurdly tiny volume of the phase space of
possible universes – about 10exp(10)exp(123) – of the entire volume, for the
situation under consideration“, (PeR) p. 444.
„The chaotic inflation state of the early universe does not match to
the second law of thermodynamics as this law requires a permanent increase of
the entropy of the universe over time, while the cosmos started with an
incredible low probability, but also with an incredible high ordered state“,
(PeR1) pp. 122 ff.
„It (the expanding universe) starts with high-entropy singularity
which, it seems, could have been an initial state for our actual universe, and,
indeed, would be a far more probable initial state (i.e. of much larger
entropy) than the Big Bang that actually occurred. The black holes that congeal
together in the final stage of our envisaged collapse would, when time-reversed
to an expanding universe, provide us with the image of an initial singularity
consisting of multiply bifurcating white holes! A white hole is the time-reverse
of a black hole, and I have indicated the sort of situation that this provides
us with in Fig. 2,45. It is the total absence of such white-hole singularities
that singles out our Big Bang as being so extraordinarily special“, (PeR1)
p. 125.
„Particles illuminated by a beam of light or infrared radiation, having
sufficient flux density, can move in various directions. This phenomenon has
been mentioned by Thoré (1877), first described and later intensively studied
by Ehrenhaft (1918) and co-workers/students. Since light is the cause for
motion, the expression „photophoresis“ has become common. Preining (1966) gives
a concise description of the important factors influencing photophoretic
motion: „This motion can depend on the illumination, color, structure and
shape of the light beam, on pressure and composition of the gas, on the
particle’s size, shape and material, and on additional fields such as electric,
magnetic, and so on“, (HoH).
(25) Wavelets: a mathematical microscope
Wavelet analysis can be used as a mathematical
microscope, looking at the details that are added if one goes from a scale
"a" to a scale "a+da", where " da " is
infinitesimally small. The mathematical microscope wavelet tool 'unfolds' a
function over the one-dimensional space R into a function over the
two-dimensional half-plane of "positions" and "details".
This two-dimensional parameter space may also be called the position-scale
half-plane.
The wavelet theory is established in the Fourier
Hilbert space framework. In order to apply the Calderón inverse formula in
a Hilbert scale framework it requires the so-called admissibility
condition defining a wavelet. "A wavelet synthesis can be performed
locally as opposed to the Fourier transform which is inherently
nonlocal due to the space-filling nature of the trigonometric functions. ….The wavelet transform unfolds any signal (e.g. in time) or any field (e.g.,
in three-dimensional space) into both space (or time) and scale (or time
scale), and possible directions (for dimensions higher than one). … „Decomposing
a vector field into orthogonal wavelets, scale-dependent distributions can be
quantified at different length scales and in different directions and hence
longitudinal or transverse contributions can be determined. In the case of an
imposed magnetic field the constructions in the directions perpendicular or
parallel to it can be dinstinguished“, (FaM1). „In practice the Fourier
transform may be thought of as embedded into the wavelet transform, because it
is, to first approximation, possible to compute the Fourier spectrum of a
signal by summing its wavelet coefficients over all positions scale by scale. …
In practice the wavelet should also be well-localized in both physical and
Fourier spaces“, (FaM).
