(1) The
Two basic facts about physics: scale dependence & decoupling
Physics
is scale dependent. Physics at large scale (largely) decouples from the physics
at a smaller level. In classical mechanics we deal with three scales according
to its 3 basic measurements (distance D, time T, mass M). In non-relativistic
quantum theory (M can be expressed through T & D using the Planck constant)
and classical relativity (T can be expressed via D using the speed of light) we
have 2 scales. In relativistic quantum theory we only have 1 scale – the scale
of distance D (or equivalently – the (inverse) scale of momenta), (BrK14) p. 9.
(2) Renormalization
groups
The
behavior of a physical system depends on a scale (of energies, distances,
momenta, etc.) at which the behavior is studied. The change of a behavior when
the scale is changed, is described by the renormalization group equation. In
quantum field theory, the dependence of the behavior on the scale is often
expressed mathematically by the fact that in order to regularize (i.e. render
finite) Feynman diagram integrals one must introduce auxiliary scales, cutoffs,
etc. The effect of these choices on the physics is encoded into the
renormalization group equation. This equation then becomes an important tool
for the study of physical theories.
Very
generally speaking, the method of renormalization group is a method designed
how to describe how the dynamics of some system changes when we change the
scale (distance, energies) at which we probe it, (BrK14) p. 9.
(3) Temperature on microscopic and macroscopic
level
Temperature
on microscopic level is basically nothing else than the average kinetic energy
of a particle established by the law of nature m*v*v = 2*k*T, (UnA1) p. 181.
Temperature
on the macroscopic (gravitational potential) level is simply energy per mass,
i.e. the combination of Einstein’s
mass-energy conservation law (E=m*c*c) and the definition of temperature in the
form 1/T = (k/W) * (dW/dE).
(4) The Planck action constant
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), see also (RoP1).
(5) Only Stewart’s law of thermal emission, not Kirchhoff’s, is fully valid
Kirchhoff’s
law considers blackbody radiation to be a universal process, independent of the
nature and shape of the emitter. Nonetheless, Kirchhoff did require, at the
minimum, thermal equilibrium with an enclosure. … Blackbody radiation, as
experimentally produced in cavities and as discussed theoretically, has
remained dependent on thermal equilibrium with at least the smallest carbon particle.
… Planck’s treatment of Kirchhoff’s law is examined in detail and the shortcomings
of his derivation are outlined. It is shown once again, that universality does
not exist. Only Stewart’s law of thermal emission, not Kirchhoff’s, is fully
valid, (RoP3).
(6) 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. (7) 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.
(8) 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“.
(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, (BrK14) p. 30, (PlJ).
(10) Potentially incompatible (velocity) NSE- and (pressure) Neumann-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.
„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).
(15) Einstein, Lorentz, and Ehrenhaft and the phenomenon of light
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.
(16)
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). The
subject of an indefinite inner product space first appeared in a paper of Dirac
(DiP3) on quantum field theory. Soon afterwards, Pontrjagin (PoL) gave the
first mathematical treatment of an indefinite inner product space, (BoJ)
preface.
(17) The
Stern-Gerlach experiment
The Stern-Gerlach
experiment showed that there is a magnetic property of the observed “electron”,
which is not reflected by the “Schrödinger” energy term.
(18) The Dirac
equation
The conclusions
out of the Stern-Gerlach experiment lead to the theoretical concept of the
“hypothesis of an electron spin” accompanied by an additional assumed angular
momentum (energy) of an “electron”, resulting into Dirac’s model of a bounded
electron in a hydrogen atom. Later, the Dirac model turned out to be a
relativistic model of an “electron” in contrast to the non-relativistic
Schrödinger model.
(19) The
Lamb-shift phenomenon
The Lamb-shift
phenomenon falsified the Dirac model. It
is interpreted as a consequence of interaction between the electron and
fluctuations of a quantized radiation field. Assuming that the bounded electron has
two complementary kinetical energies, a
spin-orbit momentum and a spin-angular momentum, Sommerfeld derived an adapted
energy (approximation) formula to the Dirac energy, which mathemtically required
the introduction of the so-called “fine structure” constant, (MaW) S. 71 ff. The „Lamb shift“ phenomenon is interpreted as the radiation
correction term of this approximation, (BrK14) p. 13.
(20) The
Beta-decay process of a „neutron“
On
average the Beta-decay change process of a neutron into a proton, an electron,
and an antineutrino lasts 15 minutes; its root cause is unknown.
(21) Dissolution
decay of the sun‘s pentagonal surface structure
The
sun surface shows mainly a pentagonal structure. On average they dissolve after
15 minutes, (UnA4) S. 85.
(22) 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).
(23)
Dirac’s nucleon model
Dirac‘s
physical substance called „nucleon“ has two states, called „neutron“ and
„proton“. The „folding over/flipping“ between the „up“ and „down“ states is
called „weak (force) interaction“.
(24) Dirac’s
„Large Number Hypothesis“
Dirac’s
„Large Number Hypothesis“ links the size and mass of the universe with the
ratio of the two forces at work when a „proton“ and an „electron“ in a hydrogen
atom orbit one another, (UnA1) p. 152.
(25) The
spin(1/2) hypothesis and SU(2)
The
spin(1/2) hypothesis is a consequence of the Stern-Gerlach experiment
demonstrating that in quantum physics the spatial orientation of angular
momentum is quantized. The experimental observations of the spectra of atoms
and their decomposition into magnetic and electric fields showed a
decomposition of spectral lines or of electron beams into an even number of
components, while the angular momentum multiplets were only composed by an odd
number of multiplets with the numbers , (RoH) p. 217. The
spin of an elementary particle is its eigen-rotation with exactly two rotation
axes, one parallel and one anti-parallel axis to a magnetic field. This is the
2x2 complex number scheme SU(2), where every „normal“ rotation is contained
twice. Consequently, an electron has a charge only half of the Planck’s quantum
of action.
(26) The unit quaternions and SU(2)
The
unit quaternions are isometric to SU(2), (EbH).
(27) The quaternion rotation operator
The
quaternions provide an appropriate field to address the „translation-rotation“
(linear and angular rotation) „permutation“ requirement. The perhaps primary
application of quaternions is the quaternion rotation operator. This is a
special quaternion triple-product (unit quaternions and rotating imaginary
vector) competing with the conventional (Euler) matrix rotation operator.The quaternion otation operator can be interpreted as a frame or a point-set rotation, (KuJ). Its outstanding advantages compared
to the Euler geometry are
- the axes of rotation and angles
of rotation are independent from the underlying coordinate system and
directly readable - there is no need to to take care about the sequencing of the rotary axes.
(28) Determining nuclear spin
„Each nucleus has an intrinsic
angular momentum which interacts with angular momenta of electrons or other
nuclei. It is measured in units of the Planck constant and, according to
quantum mechanics, can take only integral or half-integral values. Three methods
of determining nuclear spin are: - Hyperfine
structure of spectra The
interaction of the magnetic moments of the electrons and the nucleus may
separate in energy the states of the atom corresponding to various relative
orientations of these two magnetic moments. … - Zeeman
spectra The
magnetic moment associated with nuclear spin can interact with an external
magnetic field. … - Band
spectra Intensity
variations of alternate lines in the band spectra of diatomic molecules with
identical nuclei yield nuclear spin. …“, (BeH) p. 19.
(29) Gauge invariance
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.
(30)
The Standard Model of Elementary Particles (SMEP)
The
Standard Model of Elementary Particles (SMEP) is about
three decoupled, not complete, but consistently
defined physical theories, (GlJ). The common denominator of those three
theories is the quantum mechanics, which is based
on an axiomatic structure in a Hilbert space framework, (NeJ). The SMEP is concerned with gauges theory and variational principles. The gauge invariance
is the main principle in current SMEP theory. Each of the three observed or
assumed „forces“, the weak & strong forces of particle interactions, and
the electromagnetic interactions are related to a specific gauge group. Conceptually,
the SMEP starts with a set of fermions, e.g. the electron in quantum
electrodynamics.
(31) Scattering processes
„Scattering processes are an important theoretical
tool to explore microscopic interaction effects. The interpretation of the
considered experiments resulted into the large number of propagated elementary
particles of the SMEP, because on the short range energy level there was the
need for two additional „strong and weak“ EP interaction interpretations. The
current supposition is that there are three related quantum field theories, the
QED, the QCD, and the QFD“, (WaA) p. 189.
(32) The three gauge groups U(1), SU(2), SU(3) of the SMEP
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. The charged particles W(+), W(-)
have resemblance to positrons and
electrons, and the neutral Z particle corresponds to the photon,
(UnA3) S. 191. It describes the
„how“ of the beta-decay process. This is the (about 15 minutes) decay of a
neutron into a proton, an electron, and an antineutrino. Unfortunately, this
(weak interaction process) theory does not say anything about the „why“
accompanied by related physical laws.
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.
(33) Gauge symmetry break down
For gauge invariances 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.
(34)
The principle of transfer causality in classical mechanics and SMEP
Classical mechanics
is concerned with kinematics and dynamics. Classical
kinematics deals with the different forms of the movement of bodies in a
space-time environment. Classical dynamics should explain the reasons
of the connection of those different form of movements. The common denominator
of all dynamical models in physics is the principle of transfer
causality, ("Prinzip der Übertragungs-Kausalität", or, Impetusprinzip, (WoM).
In
the SMEP "the principle of transfer causality" leads
to the invention of two types of quantum elements, the fermions and the
bosons. Correspondingly there are three decoupled electromagnetic, weak
and strong interaction models of the SMEP equipped with
related decoupled fermion and boson groups and accompanied
with related groups of arbitrary (free) parameters w/o any physical
meaning. In the GRT "the principle of transfer causality" is
addressed by the principle that "the boundary of the boundary of a
manifold is zero", ((CiI) p. 49.
(35)
Different numbers of scales in the classical-macro-micro
worlds
In
classical mechanics one deals with the three scales, „distance“, „time“, and
„mass“; in non-relativistic quantum theory and classical relativity one deals
with two scales, „distance“, and „time“; in relativistic quantum theory one
deals with only one scale, the „distance“, (DeP) p. 551.
(36) Scale dependent/decoupling physics
requiring renormalization groups
The
down (complexity) causality thinking results into a degrease of
the number of scales, while the number of «nature constants»
increases. The effect of the required auxiliary scales, cutoffs,
etc. on the physics is encoded into the renormalization group
equation. The "case" if there is no related (G-invariant)
renormalization realisation (example ground state energy) is called
"symmetry break down", (DeP1) p. 1119 ff.
(37)
A mathematical microscope being well-localized in physical spaces
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).
(38) The full group of Lorentz transformations
„The full group of Lorentz transformations is the group of transformations that leaves the Minkowski metric invariant. But in the space of all possible Lorentz transformations there is no continuous path that starts out at the Identity, and so are the pure Lorentz boosts, but one cannot reach Parity by pure boosts or pure rotations or combinations of the two. So the real Lorentz group splits up into at least two disconnected components: the Lorentz transformations that one can reach via continuous path from the Identity (the „restricted“ Lorentz transformations), and the Lorentz transformations that one can reach via continuous path from Parity. And there is another split, namely the split between the Lorentz transformations that include Time Reversal and the ones that do not. So the Lorentz group has at least disconnected components. In fact it has exactly four disconnected components. …. The classical real Klein Gordon field is a real scalar field whose field values are invariant under the restricted Lorentz transformations. The restricted Lorentz transformations are the ones that are continuously connected to the Identity. They include spatial rotations and Lorentz boosts. They include neither P nor T nor PT. The law of evolution on the Klein Gordon field, the Klein Gordon equation is invariant under the restricted Lorentz tranformations“, (CaC) p. 636.
(39) The three related sub-groups of the Lorentz group
There are three related sub-groups of the Lorentz group, (A) the orthochronous Lorentz group (containing „1“ and the space inversion); (B) the proper Lorentz group (containing the „1“ and the space-time inversion; it is associated to the group of complex matrices of determinant one, which is denoted by ), which is important in describing the tranformation properties of spinors), and (C) the orthochorous Lorentz group (containing the space inversion and the time inversion).
(40) The complex Lorentz group
The complex Lorentz group is associated with SU(2) x SU(2). It is the set of all pairs of 2x2-matrices of determinant one accompanied by a multiplication law. While two (real) Lorentz transformations need to be connected to one another by an appropriately defined continuous curve of Lorentz transformations (the Lie group concept), there are two pairs of components of the complex Lorentz group, which are both already connected by definition accompanied by a related multiplication law, (BrK0) p. 48.
(41) The PCT Theorem
The complex Lorentz
group SU(2) x SU(2) plays a key role in the proof of the PCT theorem,
where PCT stands for P = space inversion; T = time inversion; C = charge
conjugation, (StR). This theorem is one of the rarely physical theorem, which
is mathematically proven like the Noether theorem.
(42) The Coulomb problem and SU(2)xSU(2)
The complex Lorentz group SU(2) x SU(2) is the hidden symmetry group of the Coulomb problem, (RoH) p. 172.
(43) The Yang-Mills mass gap
The classical Yang-Mills theory is the generalization
of the Maxwell theory of electromagnetism where the chromo-electromagnetic
field itself carries charges. As a classical field theory it has solutions
which travel at the speed of light so that its quantum version should describe
massless particles (gluons). However, the postulated phenomenon of color confinement
permits only bound states of gluons, forming massive particles. This is the
mass gap.
(44) A mathematical curiousity in the
electroweak theory
„In the standard model the weak and the electromagnetic
interactions are unified in what is called electroweak theory, where there is a
special symmetry related to W(+), W(-), Z, and the photon, according to the
groups SU(2)xU(1) or, more correctly, U(2). The group might be expressed as
SU(2)/U(1)/Z(2), where the „Z(2)“ means „factor out by a Z(2) subgroup“. However, there is more than one
such subgroup, so this notation is „Z(2)“
not fully explicit. The notation „U(2)“ automatically picks out the correct
one. (I am grateful to Florence Tsou for this observation.) It seems that the
reason that the electroweak symmetry group is not conventionally referred to as
„U(2)“ is that this does not easily extend to the symmetry of the full standard
model, which also incorporates the strong symmetry group SU(2), the full group
being a version SU(3)xSU(2)xU(1)/Z(6)“, (PeR4) p. 641, 654.
(45) Quantum fluctuations, the Casimir and the Lamb shift phenomena
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. (46) The supergravity phase after "Big Bang"
According to the “Big-Bang
Theory” in the early universe pressures and temperature
prevented the permanent establishment of elementary particles. None of the
invented elementary particles of the SMEP were able to form stable objects
until the universe had cooled beyond the so-called „supergravity phase“. (47) SMEP and the inflation phase after "Big Bang"
The
SMEP does not
provide any explanation where the related elementary „particles“ were
built from during the inflation phase of the current big bang story and
why their mass
have their specific values.
(48) 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 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).
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. This means that the Higgs mechanism requires a Higgs field with not vanishing
amplitudes in the ground state. The mechanism is therefore incompatible with the SMEP.
(49) 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.
(50) The free electron (Fermi gas) model in solid state
physics
"According to the „free electron model“ the valence
electrons of the constituent atoms become conduction electrons and move about
freely through the colume of the metal. Even in metals for which the free
electron model works best, the charge distribution of the conduction electrons
reflects the strong electrostatic potential of the ion cores. The utility of
the free electron model is greatest for properties that depend essentially on
the kinetic properties of the conduction electrons. The free electron model of
metals gives good insight into the heat capacity, thermal conductivity, electrical
conductivity, magentic susceptibility", (KiC) p. 163.
(51) Free-electron
theory and an infinite resistance of insulators
„The success of
Bohr’s early and pioneering ideas on the atom was always a rather narrow one
and the same applies to Ptolemy’s epicycles. Our present vantage point gives an
accurate description of all phenomena which these more primitive theories can
describe. The same is not true any longer of the so-called free-electron
theory, which gives a marvelously accurate picture of many, if not most,
properties of metals, semiconductors, and insulators. In particular, it
explains the fact, never properly understood on the basis of the "real
theory," that insulators show a specific resistance to electricity which
may be 10exp(26) times greater than that of metals. In fact, there is no
experimental evidence to show that the resistance is not infinite under the
conditions under which the free-electron theory would lead us to expect an
infinite resistance. Nevertheless, we are convinced that the free-electron
theory is a crude approximation which should be replaced, in the description of
all phenomena concerning solids, by a more accurate picture. If viewed from our
real vantage point, the situation presented by the free-electron theory is
irritating but is not likely to forebode any inconsistencies which are
unsurmountable for us. The free-electron theory raises doubts as to how much we
should trust numerical agreement between theory and experiment as evidence for
the correctness of the theory. We are used to such doubts“, (WiE).
(52) The physics of superconducting state
„The electrical resistivity of many metals and alloys
drops suddenly to zero when the specimen is cooled to a sufficiently low
temperature, often a temperature in the liquid helium range“, (KiC) p. 259. … „The
Meissner effect shows that a bulk superconductor behaves as if the magnetic
field B inside the specimen vanishes“, (KiC) p. 262. … „The result B=0 cannot
be derived from the characterization of a superconductor as a medium of zero
resistivity“. However, from Ohm’s law one may concluded that „the flux through
the metal cannot change on cooling through the transition. The Meissner effect
suggests that perfect diamagnetism is an essential property of the
superconducting state“, (KiC) p. 263. … „An energy gap is a characteristic, but
not universal, feature of the superconductivity state. The gap is accounted for
by the Bardeen-Cooper-Schrieffer (BCS) theory of superconductivity. The energy
gap of superconductors is of entirely different origin and nature than the
energy gap of insulators. In an insulator the energy gap is caused by the
electron-lattice interaction. This interaction ties the electrons to the lattice.
In a superconductor the important interaction is the electron-electron
interaction which orders the electrons in k-space with respect to the
Fermi gas of electrons“, (KiC) p. 266. … „The basis of a quantum theory of
superonductivity was laid by the classic 1957 papers of Bardeen, Cooper, and
Schrieffer“, (KiC) p. 277. … „The flux quantum is called fluxoid or fluxon“,
(KIC) p. 281. … „There is no difference in the mechanism of superconductivity
in type I and type II superconductors. Both types have similar thermal
properties at the superconductor-normal transition in zero magnetic field. But
the Meissner effect is entirely different“, (Kic) p. 283.
(53) The BCS theory and Cooper pairs
„Ausganspunkt der von Bardeen, Cooper, and Schrieffer
gegebenen mikroskopischen Theorie ist das Vorhandensein von Cooper-Paaren.
Diese Quasiteilchen haben, ohne daß ein Suprastrom fließt, den
Schwerpunktimpuls Null bzw. bei Vorliegen eines Suprastromes den einheitlichen
Schwerpunktimpuls >0. Nach der Heisenbergschen Unschärferelation ist ihre
räumliche Lage im Supraleiter völlig unbestimmt oder anders ausgedrückt, ihre
Wellenfunktion ist über den gesamten Supraleiter ausgedehnt“, (WeC) S. 563.
(54) The London dispersion forces
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, Wikipedia.
(55)
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).
(56) Relativity theory & quantum theory describe
two different universes
„Obviously, the two theories, the relativity theory and the quantum theory,
describe two different universes. The doubters in this little fairy tale asked,
why there flowed out exactlty the right quantity of gas from the Ur-hole
ensuring that the sun can continue to burn evently. …There are computer
simulations of universes with different constants of Nature. …There is perhaps
a superordinated reason, which is not discovered yet. There are different
conceivable explanations to this point:
- pure conincidence
- a creator has built that universe
- superordinated laws establish the constants of Nature
- there are multiple universes.
The fourth option is a special case of the third one“, (GaG3) S. 107/108.
(57) The phenomenon of plasma matter
About
95% of the universe is about the phenomenon „vacuum“. The same proportion
applies to the emptyness between a proton and an electron. The remaining 5% of
universe’s vacuum consists roughly of 5% matter, of 25% sophisticated „dark
matter“, and of 70% sophisticated „dark energy“. Nearly all (about
99%) of the 5% matter in the universe is in "plasma state". A
presumed physical concept of „dark matter“ „explains“ the phenomenon of
the spiral shapes in the universe. A presumed physical concept of „dark energy“
explains the phenomenon of the cosmic microwave background.
(58) Microwave radiation pressure to plasma (ponderomotive
force)
Light
waves exert radiation pressure which is usually very weak and hard to detect. …
When high-powered microwaves or laser beams are used to heat or confine plasmas
the radiation pressure can reach several hundred thousand atmospheres! When
applied to plasma, this force is coupled to the particles in a somewhat subtle
way and is called the ponderomotive force. Many nonlinear phenomena have a
simple explanation in terms of the ponderomotive force, (BrK14) p. 19
(59) The Landau damping phenomenon
The Landau damping phenomenon is a
characteristic of collisionless plasma dynamics (i.e. there is no
mechanical particle interactions); it is governed by the Coulomb
potential.
(60) The Debye length
The Debye length is an important physical
parameter for the description of a plasma. It provides a measure of the
distance over which the influence of the electric field of an individual
charged particle (or of a surface at some nonzero potential) is felt by
the other charged particles inside the plasma. The charged particles
arrange themselves in such a way as to effectively shield any
electrostatic fields within a distance of the order of the Debye length.
… It is convenient to define a Debey sphere as a sphere inside the
plasma of radius equal to the Debye length, (BiJ) p. 8.
(61)
Two incompatible math. models of the Landau damping phenomenon
„There are actually two kinds of the plasma Landau damping phenomenon: linear Landau damping, and
nonlinear Landau damping. Both kinds are independent of dissipative collisional
mechanisms. If a particle is caught in the potential well of a wave, the
phenomenon is called „trapping“. Particles can indeed gain or lose energy in
trapping. However, trapping does not lie within the purview of the linear
theory. …. Trapping is not in the linear theory. When a wave grows to a larger
amplitude, collisonless damping with trapping occur. One then finds that the
wave does not decay monotonically; rather the amplitutes fluctuates during the
decay as the trapped particles bounce back and forth in the potential wells.
This is nonlinear Landau damping. .. Since the linear Landau damping is
derived from a linear theory, … the nonlinear Landau damping must arise from a
different physical effect. The question is: Can untrapped electrons moving
close to the phase velocity of the wave exchange energy with the wave?“,
(ChF) p. 248-249.
(62) 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).
“, (GaG3) S. 107/108.
(63) General relativity made up of fields on fields
"General
relativity is the discovery that spacetime and the gravitational field are the
same entity. What we call „spacetime“ is itself a physical object, in many
respects similar to the electromagnetic field. We can say that GR is the
discovery that there is no spacetime at all. What Newton called „space“, and
Minkowski called „spacetime“, is unmasked: it is nothing but a dynamic object –
the gravitational field – in a regime in which we neglect its dynamics. …., the
universe is not made up of fields on spacetime; it is made up of fields on
fields", (RoC).
(64) The
boundary of the boundary principle and geometrodynamics
Einstein's "general relativity" or "geometric theory of gravitation" or "geometrodynamics", has two central ideas:
(1)
Spacetime geometry "tells" mass-energy how to move; and (2)
mass-energy "tells" spacetime geometry how to curve. ad
(1): We have just seen that the way spacetime tells mass-energy how to move, is
automatically obtained from the Einstein field equations by using the identity
of Riemannian geometry, known as the Bianchi identity, which tells us that the
covariant divergence of the Einstein tensor is zero. In
other words, Einstein geometrodynamics has the important and beautiful property
that the equations of motion are a direct mathematical consequence of the
Bianchi identities. ad
(2): According to an idea of extreme simplicity of the laws at the foundations
of physics, what one of us has called „the principle of austerity“ or „law
without law at the basis of physics“, in geometrodynamics it is possible to
derive the dynamical equations for matter and fields from the extremely simple
but central identity of algebraic topology: the principle that the boundary of
the boundary of a manifold is zero“, (CiI) p. 49
(65) The prize for a physical “purely
geometrodynamics” interpretation
„The prize being paid for a physical “purely geometrodynamics”
interpretation is
1. giving up the fundamental principle of nature, the least
action principle
2. requiring so-called Einstein spaces
a. gravitation models without sources
b. not identical with SRT-Minkowski space equipped
with an indefinite
inner product,“ (TrH1).
(66) 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).
(67) 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.
(68)
The "Evolution Problem in General Relativity & physical "black holes"
The
mathematical framework of the General Relativity Theory (GRT) does not allow
the derivation of the laws of gravitational radiation as dynamic developments
of initial data sets, (ChD). The "Evolution Problem in General
Relativity", i.e., the full solution of the radiation problem in
vacuum for arbitrary asymptotically flat inital data sets, (KlS1), is
about a not well-posed, (LoA1), nonlinear hyperbolic partial differential
equation system on Riemann manifolds equipped with the Einstein metric accompanied by mathematical singularities and related physical
"black holes", (PeR) p. 444.
(69)
The Cosmological Microwave Background Radiation and Big Bang models
The
CMBR provides us with the most important evidence supporting the Big Bang
model. Big Bang models are on the basis of general relativity and follow from a
number of assumptions, (LaM) p. 7:
- homogeneity of space applies. Thus it is assumed that all points of space are
equivalent and the properties associated with each point are the same
- isotropy of space applies. This means that there is no privileged direction in
space
- the matter in the universe can be described very simple in terms of what is
called a perfect fluid. In this case its properties are completely given by its density and its pressure
- the laws of physics are the same everywhere.
(70)
Gödel’s new type of cosmological solutions of the gravity field equations
All
cosmological solutions with non-vanishing density of matter known at present
have the common property that, in a certain sense, they contain an „absolute“
time coordinate, owing to the fact that there exists a one-parametric system of
three-spaces everywhere orthogonal on the world lines of matter. It is easily
seen that the non-existence of such a system of three-spaces is equivalent with
a rotation of matter relatively to the compass of inertia. In this paper I am
proposing a solution (with a cosmological term
) which exhibits
such a rotation. This solution, or rather the four-dimensional space S which it
defines, has the further properties
1. S is homogeneous 2. …. so that any two world lines of matter are equidistant 3. S has rotational symmetry 4. … That is, a positive direction of time can consistently be introduced in the
whole solution 5. It is not possible to assign a time coordinate to each space-time point in such
a way that the coordinate always increases, if one moves in a positive
time-like direction; … 6. … it is theoretically possible in these worlds to travel into the past, or
otherwise influence the past 7. There exist no three-spaces which are everywhere space-like and intersect each
world line of matter in one point 8. … an absolute time does not exist, even if it is not required to agree in
direction with the times of all possible observers (where absolute means:
definable without reference to individual objects, such as e.g. a particular
galactic system).
Matter everywhere rotates relatively to
the compass of inertia with the angular velocity constant depending from the
mean density of matter and Newton’s gravitational constant, (BrK14) p. 35.

The most advanced mathematics of “galactic dynamics”
The
most advanced mathematics of “galactic dynamics” is about collisionsless
Boltzmann and Poisson equations accompanied by the probability of a given star
to be found in unit phase-space volume near the phase-space position , (BiJ) p. 555.
(72)
The "Unfinished Revolution" in physics
The
mathematical modelling framework of the GRT (manifolds and all that) is
incompatible to the mathematical framework of the SMEP. The scope of the "Unfinished
Revolution" in physics regarding the two discoveries, the relativity
and the quantum, is described by Smolin's "five unsolved problems
in the theoretical physics", (SmL1).
(73)
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.
(74) A Heuristic
Approach to General Relativity
The article "A Heuristic
Approach to General Relativity", (DeH), explains all known tests of
Einstein's general relativity theory with variable speed of light, (UnA1) p.
142.
(75) The Mach principle
"Einstein associated with
Mach’s name two specific problems.
The first may be called the absolute-space problem, but it could
equally well be called the problem of the distinguished frames of references. …
The second may by called the inertial-mass problem. This problem
was first mentioned explicitly by Einstein in 1912, when he asserted that Mach
had sought to explain the inertial mass of bodies through a kind of interaction
with all masses of the universe", (BaJ), (UnA1) p. 65.
(76) Mach‘s distribution of masses througthout the universe
"Mach
conjectured that distant celestial objects must also be responsible for masses
having gravitational properties. … according to Mach’s hypothesis the
acceleration of a falling apple would not only be determined by Newton’s
(supposedly) universal gravitational constant, but also by the distribution of
masses throughout the universe! … In contrast, for example, electrical
charges have nothing to do with inertia, while mass is „heavy“ and „inert“ at
the same time“, (UnA1) pp. 65/66.
(77) Einstein's lost key: a variable speed of light
"Nothing
forces us to assume that ... clocks have to be seen as running at the same
speed", (UnA1) p. 12. ... The formula for gravitational
potential he had developed in his variable speed of light article implied that
the graviational constant itself could be calculated from the mass distribution
of the universe", (UnA1) p. 15. ... Dicke later became famous
for his role in the discovery of the cosmic microwave background, and only bad
luck prevented him from winning the Nobel Prize. Dicke, who studied Ernst Mach,
saw the power of Einstein's formula - and improved it in one crucial respect" (UnA1) p. 16.
(78) Differentiable Riemann manifolds
The key ingredients of Einstein’s field equations are Riemann's
differentiable manifolds (whereby the differentiability condition is w/o any
physical meaning) in combination with the concept of affine connexion (enabled
by the differentiability condition) to build the metric g based (Riemann
manifold) metric space (M,g).
(79) Inflations and time bomb solutions of Einstein's field equations
Einstein’s field equations are hyperbolic and allow so called „time
bomb solutions“ which spreads along bi-characteristic or characteristic
hyper surfaces. Actual quantum theories are talking about „inflations“, which
blew up the germ of the universe in the very first state. The inflation field
due to these concepts are not smooth, but containing fluctuation quanta. The
action of those fluctuations create traces into a large area of space.
(80) Schrödinger’s
forgotten cosmological hypothesis „Schrödinger
suspected that all the potentials in the universe might just add up to the
square of the speed of light c, (UnA1) p. 120: „This remarkable relationship states
that the (negative) potential of all masses at the point of observation,
calculated with the gravitational constant valid at the observation point, must
be equal to half the square of the speed of light“. „Thus only a a vanishingly small
fraction of the inertial effect observed on Earth and in the solar system can
originate from their interaction with the masses of the Milky Way“. He
was the first to suspect the coincidence between the gravitational potential
constant divided by the square of the speed of light and the ratio between the
radius of the universe and the total mass of the universe“, (UnA1)
p. 118.
(81)
Dirac’s two „large number hypotheses“
"Dirac
had discovered the coincidence between the size of the proton and the size of
the universe. Dirac also noticed the approximately same ratio number (about
10exp(40) as the ratio between the electrical force and the gravitational force
between the proton and the electron in a hydrogen atom and the ratio of the visible
horizon of the universe and the radius of the proton, (UnA2) p. 73. This is what is called Dirac’s first „large
number hypothesis. Dirac's second „large number hypothesis“ is based on the coincidence of the ratio
between the square of the latter ratio (i.e., the ratio of visible horizon of
the universe and the radius of the proton) and the ratio of all masses in the
universe and the mass of the proton", (UnA1) p. 156, (UnA2) p. 82.
"Why
are coincidences such as Dirac’s considered exotic? Assuming that the number of
hydrogen atoms in the universe is proportional to the square of ist size indeed
appears grotesque: as if the amount of matter in the universe had to do with its surface, rather than with its volume", (UnA) p. 156.
