Two controversial authors debate the nature and methods of science,
its dogmas, and its future. Rupert Sheldrake argues that science
needs to free itself from materialist dogma while Michael Shermer
contends that science, properly conceived, is a materialistic
enterprise; for science to look beyond materialist explanations is
to betray science and engage in superstition. Issues discussed
include: materialism and its role in science, whether belief in God
is compatible with a scientific perspective, and parapsychology.
Michael Shermer is Editor-in-Chief of "Skeptic "magazine and the
author of numerous books including "Skeptic."Rupert Sheldrake is a
biologist and author of ten books including his most recent,
"Science Set Free," which challenges scientific dogma.
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.
On March 21, 2013, the European Space Agency released a map of the
afterglow of the Big Bang. Taking in 440 sextillion kilometres of
space and 13.8 billion years of time, it is physically impossible
to make a better map: we will never see the early universe in more
detail. On the one hand, such a view is the apotheosis of modern
cosmology, on the other, it threatens to undermine almost
everything we hold cosmologically sacrosanct. The map contains
anomalies that challenge our understanding of the universe. It will
force us to revisit what is known and what is unknown, to construct
a new model of our universe. This is the first book to address what
will be an epoch-defining scientific paradigm shift. Stuart Clark
will ask if Newton's famous laws of gravity need to be rewritten;
if dark matter and dark energy are just celestial phantoms? Can we
ever know what happened before the Big Bang? What's at the bottom
of a black hole? Are there universes beyond our own? Does time
exist? Are the once immutable laws of physics changing?
"Heart of Darkness" describes the incredible saga of humankind's
quest to unravel the deepest secrets of the universe. Over the past
thirty years, scientists have learned that two little-understood
components--dark matter and dark energy--comprise most of the known
cosmos, explain the growth of all cosmic structure, and hold the
key to the universe's fate. The story of how evidence for the
so-called "Lambda-Cold Dark Matter" model of cosmology has been
gathered by generations of scientists throughout the world is told
here by one of the pioneers of the field, Jeremiah Ostriker, and
his coauthor Simon Mitton.
From humankind's early attempts to comprehend Earth's place in
the solar system, to astronomers' exploration of the Milky Way
galaxy and the realm of the nebulae beyond, to the detection of the
primordial fluctuations of energy from which all subsequent
structure developed, this book explains the physics and the history
of how the current model of our universe arose and has passed every
test hurled at it by the skeptics. Throughout this rich story, an
essential theme is emphasized: how three aspects of rational
inquiry--the application of direct measurement and observation, the
introduction of mathematical modeling, and the requirement that
hypotheses should be testable and verifiable--guide scientific
progress and underpin our modern cosmological paradigm.
The story is far from complete, however, as scientists confront
the mysteries of the ultimate causes of cosmic structure formation
and the real nature and origin of dark matter and dark energy.
