Galileo Unbound traces the journey that brought us from Galileo's
law of free fall to today's geneticists measuring evolutionary
drift, entangled quantum particles moving among many worlds, and
our lives as trajectories traversing a health space with thousands
of dimensions. Remarkably, common themes persist that predict the
evolution of species as readily as the orbits of planets or the
collapse of stars into black holes. This book tells the history of
spaces of expanding dimension and increasing abstraction and how
they continue today to give new insight into the physics of complex
systems. Galileo published the first modern law of motion, the Law
of Fall, that was ideal and simple, laying the foundation upon
which Newton built the first theory of dynamics. Early in the
twentieth century, geometry became the cause of motion rather than
the result when Einstein envisioned the fabric of space-time warped
by mass and energy, forcing light rays to bend past the Sun.
Possibly more radical was Feynman's dilemma of quantum particles
taking all paths at once - setting the stage for the modern fields
of quantum field theory and quantum computing. Yet as concepts of
motion have evolved, one thing has remained constant, the need to
track ever more complex changes and to capture their essence, to
find patterns in the chaos as we try to predict and control our
world.
This book is intended for anyone who is interested in a real
physical image and order of the physical world surrounding us.In
this book Einstein's destruction of physics is documented. The
physical reality of gravity, inertial forces, mass, time,
double-slit experiment is debunked. It shows that Quarks and Higgs
bosons do not exist and that all elementary particles, all rigid
matter and all force fields in the Universe are created from
compression of ether. It show that Einstein, after 1916 became a
more enthusiastic advocate of the proven existence of the ether
than supporters of the ether before 1905.The aim of this book is to
return physics from its way of metaphysics in the 20th century on
the way of the physical reality in the 21st century. This second
edition of this book was augmented by twenty pages compared to its
first edition. After this augmentation it appears that the
argumentation about the unacceptability of the ill-founded physical
theories of the 20th century represents a compact corpus.
Relativity has much to offer for a well-rounded education. Yet
books on relativity either assume a strong background in physics
and math, aimed at advanced physics students, or, alternatively,
offer a broad description with little intellectual challenge. This
book bridges the gap. It aims at readers with essentially no
physics or math background, who still find it rewarding to think
rigorously. The book takes a "thinking tools" approach, by first
making readers comfortable with a new thinking tool and then
applying it to learn more about how nature works. By the end of the
book, readers will have collected a versatile toolbox and will be
comfortable using the tools to think about and really understand
the intriguing phenomena they may have only heard about, including
the twin paradox, black holes, and time travel. End-of-chapter
exercises span a range of difficulty, allowing adventurous readers
to stretch their understanding further as desired. Students who
have studied, or are studying, relativity at a more mathematical
level will also find the book useful for a more conceptual
understanding.
Theoretical physics and foundations of physics have not made much
progress in the last few decades. Whether we are talking about
unifying general relativity and quantum field theory (quantum
gravity), explaining so-called dark energy and dark matter
(cosmology), or the interpretation and implications of quantum
mechanics and relativity, there is no consensus in sight. In
addition, both enterprises are deeply puzzled about various facets
of time including above all, time as experienced. The authors argue
that, across the board, this impasse is the result of the
"dynamical universe paradigm," the idea that reality is
fundamentally made up of physical entities that evolve in time from
some initial state according to dynamical laws. Thus, in the
dynamical universe, the initial conditions plus the dynamical laws
explain everything else going exclusively forward in time. In
cosmology, for example, the initial conditions reside in the Big
Bang and the dynamical law is supplied by general relativity.
Accordingly, the present state of the universe is explained
exclusively by its past. This book offers a completely new paradigm
(called Relational Blockworld), whereby the past, present and
future co-determine each other via "adynamical global constraints,"
such as the least action principle. Accordingly, the future is just
as important for explaining the present as is the past. Most of the
book is devoted to showing how Relational Blockworld resolves many
of the current conundrums of both theoretical physics and
foundations of physics, including the mystery of time as
experienced and how that experience relates to the block universe.
Canonical methods are a powerful mathematical tool within the field
of gravitational research, both theoretical and experimental, and
have contributed to a number of recent developments in physics.
Providing mathematical foundations as well as physical
applications, this is the first systematic explanation of canonical
methods in gravity. The book discusses the mathematical and
geometrical notions underlying canonical tools, highlighting their
applications in all aspects of gravitational research from advanced
mathematical foundations to modern applications in cosmology and
black hole physics. The main canonical formulations, including the
Arnowitt-Deser-Misner (ADM) formalism and Ashtekar variables, are
derived and discussed. Ideal for both graduate students and
researchers, this book provides a link between standard
introductions to general relativity and advanced expositions of
black hole physics, theoretical cosmology or quantum gravity.
