A Quantum Gate as a Physical Model of an Universal Arithmetical Algorithm without Church's Undecidability and Godel's Incompleteness
In this work we define an universal arithmetical algorithm, by means of the
standard quantum mechanical formalism, called universal qm-arithmetical
algorithm. By universal qm-arithmetical algorithm any decidable arithmetical
formula (operation) can be decided (realized, calculated. Arithmetic defined by
universal qm-arithmetical algorithm called qm-arithmetic one-to-one corresponds
to decidable part of the usual arithmetic. We prove that in the qm-arithmetic
the undecidable arithmetical formulas (operations) cannot exist (cannot be
consistently defined). Or, we prove that qm-arithmetic has no undecidable
parts. In this way we show that qm-arithmetic, that holds neither Church's
undecidability nor Godel's incompleteness, is decidable and complete. Finally,
we suggest that problems of the foundation of the arithmetic, can be solved by
qm-arithmetic.Comment: 13 pages, no figure
There is Neither Classical Bug with a Superluminal Shadow Nor Quantum Absolute Collapse Nor (Subquantum) Superluminal Hidden Variable
In this work we analyse critically Griffiths's example of the classical
superluminal motion of a bug shadow. Griffiths considers that this example is
conceptually very close to quantum nonlocality or superluminality,i.e. quantum
breaking of the famous Bell inequality. Or, generally, he suggests implicitly
an absolute asymmetric duality (subluminality vs. superluminality) principle in
any fundamental physical theory.It, he hopes, can be used for a natural
interpretation of the quantum mechanics too. But we explain that such
Griffiths's interpretation retires implicitly but significantly from usual,
Copenhagen interpretation of the standard quantum mechanical formalism. Within
Copenhagen interpretation basic complementarity principle represents, in fact,
a dynamical symmetry principle (including its spontaneous breaking, i.e.
effective hiding by measurement). Similarly, in other fundamental physical
theories instead of Griffiths's absolute asymmetric duality principle there is
a dynamical symmetry (including its spontaneous breaking, i.e. effective hiding
in some of these theories) principle. Finally, we show that Griffiths's example
of the bug shadow superluminal motion is definitely incorrect (it sharply
contradicts the remarkable Roemer's determination of the speed of light by
coming late of Jupiter's first moon shadow).Comment: 15 pages, no figure
Symmetry of the Simple Ecological Dynamical Equations
It is shown that all simple ecological, i.e. population dynamical equations
(unlimited exponential population growth (or decrease) dynamics, logistic or
Verhulst equation, usual and generalized Lotka-Volterra equations) hold a
symmetry, called symmetry. Namely, all simple ecological dynamical
equations are invariant (symmetric) in respect to successive application of the
time reversal transformation - , space coordinates reversal or parity
transformation - , and predator-prey reversal transformation - that
changes preys in the predators or pure (healthy) in the impure (fatal)
environment, and vice versa. It is deeply conceptually analogous to remarkable
symmetry of the fundamental physical dynamical equations. Further, it is
shown that by more accurate, "microscopic" analysis, given symmetry
becomes explicitly broken.Comment: 11 pages, no figure
Population Dynamics of Children and Adolescents without Problematic Behavior
In this work we suggest a simple mathematical model for the dynamics of the
population of children and adolescents without problematic behavior (criminal
activities etc.). This model represents a typical population growth equation
but with time dependent (linearly decreasing) population growth coefficient.
Given equation admits definition of the half-life time of the non-problematic
children behavior as well as a criterion for estimation of the social
regulation of the children behavior.Comment: two pages, no figure
A Simple Solution of the Lotka-Volterra Equations
In this work we consider a simple, approximate, tending toward exact,
solution of the system of two usual Lotka-Volterra differential equations.
Given solution is obtained by an iterative method. In any finite approximation
order of this solution, exponents of the corresponding Lotka-Volterra variables
have simple, time polynomial form. When approximation order tends to infinity
obtained approximate solution converges toward exact solution in some finite
time interval.Comment: 6 pages, no figure
From Quantum To Classical Dynamics: A Landau Continuous Phase Transition With Spontaneous Superposition Breaking
Developing an earlier proposal (Ne'eman, Damnjanovic, etc), we show herein
that there is a Landau continuous phase transition from the exact quantum
dynamics to the effectively classical one, occurring via spontaneous
superposition breaking (effective hiding), as a special case of the
corresponding general formalism (Bernstein). Critical values of the order
parameters for this transition are determined by Heisenberg's indeterminacy
relations, change continuously, and are in excellent agreement with the recent
and remarkable experiments with Bose condensation. It is also shown that such a
phase transition can sucessfully model self-collapse (self-decoherence), as an
effective classical phenomenon, on the measurement device. This then induces a
relative collapse (relative decoherence) as an effective quantum phenomenon on
the measured quantum object by measurement.
We demonstrate this (including the case of Bose-Einstein condensation) in the
well-known cases of the Stern-Gerlach spin measurement, Bell's inequality and
the recently discussed quantum superposition on a mirror a la Marshall et al.
These results provide for a proof that quantum mechanics, in distinction to all
absolute collapse and hidden-variable theories, is local and objective. There
now appear no insuperable obstacles to solving the open problems in quantum
theory of measurement and foundation of quantum mechanics, and strictly within
the standard quantum-mechanical formalism. Simply put, quantum mechanics is a
field theory over the Hilbert space, the classical mechanics characteristics of
which emerge through spontaneous superposition breaking.Comment: 32 page
The Simplest Determination of the Thermodynamical Characteristics of Schwarzschild, Kerr Andreissner-Nordstrom Black Hole
In this work, generalizing our previous results, we determine in an original
and the simplest way three most important thermodynamical characteristics
(Bekenstein-Hawking entropy, Bekenstein quantization of the entropy or (outer)
horizon surface area and Hawking temperature) of Schwarzschild, Kerr and
Reissner-Nordstrom black hole. We start physically by assumption that
circumference of black hole (outer) horizon holds the natural (integer) number
of corresponding reduced Compton's wave length and use mathematically only
simple algebraic equations. (It is conceptually similar to Bohr's quantization
postulate in Bohr's atomic model interpreted by de Broglie relation.)Comment: 5 pages, no figure
A "Quasi-Rapid" Extinction Population Dynamics and Mammoths Overkill
In this work we suggest and consider an original, simple mathematical model
of a "quasi-rapid" extinction population dynamics. It describes a decrease and
final extinction of the population of one prey species by a "quasi-rapid"
interaction with one predator species with increasing population. This
"quasi-rapid" interaction means ecologically that prey species behaves
practically quite passively (since there is no time for any reaction, i.e.
defense), like an appropriate environment, in respect to "quasi-rapid" activity
of the predator species that can have different "quasi-rapid" hunting
abilities. Mathematically, our model is based on a non-Lotka-Volterraian system
of two differential equations of the first order, first of which is linear
while second, depending of a parameter that characterizes hunting ability is
nonlinear. We compare suggested "quasi-rapid" extinction population dynamics
and the global model of the overkill of the prehistoric megafauna (mammoths).
We demonstrate that our "quasi-rapid" extinction population dynamics is able to
restitute successfully correlations between empirical (archeological) data and
overkill theory in North America as well as Australia. For this reason, we
conclude that global overkill theory, completely mathematically modelable by
"quasi-rapid" extinction population dynamics can consistently explain the
Pleistocene extinctions of the megafauna.Comment: 11 pages, no figure
