There has not been a scientific revolution for about 100 years. One
seems imminent, as QED has recently been violated at the Sigma-6
level. Kuhn, in 'The Structure of Scientific Revolutions', used
Wittgenstein's famous duck-rabbit optical illusion to demonstrate
how bias in interpretation causes scientists to see the same
information in radically different manners, which is likely to have
delayed the pending paradigm shift. Jean-Pierre Vigier, continually
labeled l'heretique de la physique and l'eternel resistant in
French media, remains a pillar of modern mathematical physics.
'Heretical' works of Vigier related to extended electromagnetic
theory incorporating photon mass and a longitudinal B(3) EM field,
gravity, quantum theory, large-scale additional dimensions, the
Dirac polarized vacuum and many more related issues are deemed by
his followers to be essential to the evolution of physics. The
phrase 'Lives On' was chosen in the title of this volume to claim
ignored portions of his work are relevant to implementing the
Paradigm Shift to an Einsteinian Unified Field Theory.
Specifically, chapters about the Dirac Hypertube, Tight-Bound
States and Spacetime programming provide required insights into
crossing the dimensional barrier and 'proving' parts of M-Theoretic
dimensionality. As happens periodically in the history of science,
we live in a climate where coloring outside-the-box can have severe
myopic consequences such as difficulties in passing PhD exams,
challenges in grant approval or problems in receiving tenure. Since
there is no conflict with Gauge Theory, once realized, many
chapters in this important volume will aid in facilitating progress
in physics beyond the Standard Model.
This book outlines the principles of thermoelectric generation and
refrigeration from the discovery of the Seebeck and Peltier effects
in the nineteenth century through the introduction of semiconductor
thermoelements in the mid-twentieth century to the more recent
development of nanostructured materials. It is shown that the
efficiency of a thermoelectric generator and the coefficient of
performance of a thermoelectric refrigerator can be related to a
quantity known as the figure of merit. The figure of merit depends
on the Seebeck coefficient and the ratio of the electrical to
thermal conductivity. It is shown that expressions for these
parameters can be derived from the band theory of solids. The
conditions for favourable electronic properties are discussed. The
methods for selecting materials with a low lattice thermal
conductivity are outlined and the ways in which the scattering of
phonons can be enhanced are described. The application of these
principles is demonstrated for specific materials including the
bismuth telluride alloys, bismuth antimony, alloys based on lead
telluride, silicon-germanium and materials described as
phonon-glass electron-crystals. It is shown that there can be
advantages in using the less familiar transverse thermoelectric
effects and the transverse thermomagnetic effects. Finally,
practical aspects of thermoelectric generation and refrigeration
are discussed. The book is aimed at readers who do not have a
specialised knowledge of solid state physics.

Spaces of homogeneous type were introduced as a generalization to
the Euclidean space and serve as a suffi cient setting in which one
can generalize the classical isotropic Harmonic analysis and
function space theory. This setting is sometimes too general, and
the theory is limited. Here, we present a set of fl exible
ellipsoid covers of n that replace the Euclidean balls and support
a generalization of the theory with fewer limitations.
This book uses a hands-on approach to nonlinear dynamics using
commonly available software, including the free dynamical systems
software Xppaut, Matlab (or its free cousin, Octave) and the Maple
symbolic algebra system. Detailed instructions for various common
procedures, including bifurcation analysis using the version of
AUTO embedded in Xppaut, are provided. This book also provides a
survey that can be taught in a single academic term covering a
greater variety of dynamical systems (discrete versus continuous
time, finite versus infinite-dimensional, dissipative versus
conservative) than is normally seen in introductory texts.
Numerical computation and linear stability analysis are used as
unifying themes throughout the book. Despite the emphasis on
computer calculations, theory is not neglected, and fundamental
concepts from the field of nonlinear dynamics such as solution maps
and invariant manifolds are presented.
Quantum mechanics is one of the most fascinating, and at the
same time most controversial, branches of contemporary science.
Disputes have accompanied this science since its birth and have not
ceased to this day.
"Uncommon Paths in Quantum Physics" allows the reader to
contemplate deeply some ideas and methods that are seldom met in
the contemporary literature. Instead of widespread recipes of
mathematical physics, based on the solutions of
integro-differential equations, the book follows logical and partly
intuitional derivations of non-commutative algebra. Readers can
directly penetrate the abstract world of quantum mechanics.
First book in the market that treats this newly developed area of
theoretical physics; the book will thus provide a fascinating
overview of the prospective applications of this area, strongly
founded on the theories and methods that it describes.Provides a
solid foundation for the application of quantum theory to current
physical problems arising in the interpretation of molecular
spectra and important effects in quantum field theory.New insight
into the physics of anharmonic vibrations, more feasible
calculations with improved precision.
This monograph contains papers that were delivered at the special
session on Geometric Potential Analysis, that was part of the
Mathematical Congress of the Americas 2021, virtually held in
Buenos Aires. The papers, that were contributed by renowned
specialists worldwide, cover important aspects of current research
in geometrical potential analysis and its applications to partial
differential equations and mathematical physics.
Asian studies and Physics is a unique blend rarely found in a
Western scientific classroom. The field of Asian studies is rapidly
growing and the traditional study of Asian philosophy, art,
language and literature is branching out into scientific realms. At
the same time, there is a growing need to educate our young people
in science technology and mathematics (STEM). Reaching non-science
majors with the basic principles of physics presents a particularly
unique challenge. The topics presented in this work are designed to
appeal to a wide range of students and present scientific
principles through the technology and inventions of ancient China.
We explore these ideas in their historical Chinese context and
through the lens of our current scientific understanding. Our
exploration of ancient Chinese science is not limited to just a
theoretical understanding of physical principles. One distinction
of this book is the strong "hands on" component. Detailed
laboratory experiments are included which enable students to
analyze ancient technology using modern laboratory techniques. Each
experiment introduces the historical context and provides
associated Chinese vocabulary. On the surface, these experiments
involve recreating a Chinese technology. On a deeper level, we find
connections to the scientific method and techniques of experimental
analysis. Thus, an activity such as making paper, turns into a
lesson on statistics and graphical analysis. Topics included in
this volume cover one dimensional motion, energy conservation,
rotational equilibrium and elasticity. We also explore the nature
of science and include an introduction to the Chinese language.
Laboratory experiments cover papermaking, constructing a weighing
balance and stress-strain analysis of silk.
Replication, the independent confirmation of experimental results
and conclusions, is regarded as the "gold standard" in science.
This book examines the question of successful or failed
replications and demonstrates that that question is not always easy
to answer. It presents clear examples of successful replications,
the discoveries of the Higgs boson and of gravity waves. Failed
replications include early experiments on the Fifth Force, a
proposed modification of Newton's Law of universal gravitation, and
the measurements of "G," the constant in that law. Other case
studies illustrate some of the difficulties and complexities in
deciding whether a replication is successful or failed. It also
discusses how that question has been answered. These studies
include the "discovery" of the pentaquark in the early 2000s and
the continuing search for neutrinoless double beta decay. It argues
that although successful replication is the goal of scientific
experimentation, it is not always easily achieved.
Hulchul: The Common Ingredient of MotionMotionMotionMotion and Time
Author, Sohan Jain, proposes the following in the book: Instants of
Motion, Instants of Time and Time Outage: Just as time has instants
of time, motion has instants of motion, too. Instants of time and
motion can be divided into three classes: pure instants of time,
pure instants of motion, and composite instants of time and motion.
The sequences of the three types of instants are interspersed into
a single sequence of their occurrences. A body does not experience
time during pure instants of motion, a phenomenon we will call time
outage -the cause of time dilation. Time outage is not continuous;
it is intermittent. Internal and external motion of a body and
their inheritance: Each body has, generally, two kinds of motions:
internal motion and external motion. A body goes, wherever its
outer bodies go. An inner body inherits external motion of its
outer bodies. An outer body inherits internal motion of its inner
bodies. Photons and light do not inherit motion; may be, this is
why their motions are independent of their sources. Prime ticks,
the building blocks of time and any motion: Motion of a common body
is not continuous; it is intermittent. Any kind of motion is
perceived to be made of discrete, indivisible tiny movements,
called prime ticks (p-ticks). P-ticks are to motion what elementary
particles are to matter or what photons are to light. There is time
only because there is motion. Prime ticks are events and imply
motion. Events have concurrency, which implies time. Total
concurrency hulchul, a universal constant: Concurrency events of
external and internal p-ticks of a body are precisely the instants
of motion and time. The sum of the two is called the total
concurrency hulchul (c-hulchul). Total c-hulchul is the same for
all bodies. The proposed theory possibly explains: Why a particle
accelerator works. Why atoms have compartmentalized internal
structure. Why lighter bodies, such as elementary particles and
photons, have wavy straight motion rather than straight motion. The
theory predicts: The sharing of an electron by two atoms is not
continuous; it alternates between the two atoms.
The third edition of the defining text for the graduate-level
course in Electricity and Magnetism has finally arrived! It has
been 37 years since the first edition and 24 since the second. The
new edition addresses the changes in emphasis and applications that
have occurred in the field, without any significant increase in
length.
