An authoritative and comprehensive account of an important area
centred upon Great Driffield. Great Driffield, a thriving market
town serving an extensive agricultural hinterland, stands at the
junction of the Yorkshire Wolds and Holderness. The centre of an
important Anglo-Saxon manor, in royal hands in the early middle
ages, the main settlement was transformed from a large village into
a boom town following the opening of a canal in 1770 that linked it
to the expanding markets of Hull and the West Riding; its social,
religious and political lifeflourished in the Victorian period
particularly. This volume covers its history and that of its
adjoining rural townships of Little Driffield, Elmswell and
Kelleythorpe, from the Neolithic period to the beginning of the
twenty-first century; it provides the first detailed account of the
town's trades and industries, as well as exploring landownership,
local government, and social, religious and political life. The
editors are former staff of the University of Hull.

What would it mean to apply quantum theory, without restriction and
without involving any notion of measurement and state reduction, to
the whole universe? What would realism about the quantum state then
imply? This book brings together an illustrious team of
philosophers and physicists to debate these questions. The
contributors broadly agree on the need, or aspiration, for a
realist theory that unites micro- and macro-worlds. But they
disagree on what this implies. Some argue that if unitary quantum
evolution has unrestricted application, and if the quantum state is
taken to be something physically real, then this universe emerges
from the quantum state as one of countless others, constantly
branching in time, all of which are real. The result, they argue,
is many worlds quantum theory, also known as the Everett
interpretation of quantum mechanics. No other realist
interpretation of unitary quantum theory has ever been found.
Others argue in reply that this picture of many worlds is in no
sense inherent to quantum theory, or fails to make physical sense,
or is scientifically inadequate. The stuff of these worlds, what
they are made of, is never adequately explained, nor are the worlds
precisely defined; ordinary ideas about time and identity over time
are compromised; no satisfactory role or substitute for probability
can be found in many worlds theories; they can't explain
experimental data; anyway, there are attractive realist
alternatives to many worlds. Twenty original essays, accompanied by
commentaries and discussions, examine these claims and
counterclaims in depth. They consider questions of ontology - the
existence of worlds; probability - whether and how probability can
be related to the branching structure of the quantum state;
alternatives to many worlds - whether there are one-world realist
interpretations of quantum theory that leave quantum dynamics
unchanged; and open questions even given many worlds, including the
multiverse concept as it has arisen elsewhere in modern cosmology.
A comprehensive introduction lays out the main arguments of the
book, which provides a state-of-the-art guide to many worlds
quantum theory and its problems.
What does realism about the quantum state imply? What follows when
quantum theory is applied without restriction, if need be, to the
whole universe? These are the questions which an illustrious team
of philosophers and physicists debate in this volume. All the
contributors are agreed on realism, and on the need, or the
aspiration, for a theory that unites micro- and macroworlds, at
least in principle. But the further claim argued by some is that if
you allow the Schrodinger equation unrestricted application,
supposing the quantum state to be something physically real, then
this universe is one of countlessly many others, constantly
branching in time, all of which are real. The result is the many
worlds theory, also known as the Everett interpretation of quantum
mechanics.
The contrary claim sees this picture of many worlds as in no sense
inherent in quantum mechanics, even when the latter is allowed
unrestricted scope and even given that the quantum state itself is
something physically real. For this picture of branching worlds
fails to make physical sense, let alone common sense, even on its
own terms. The status of these worlds, what they are made of, is
never adequately explained. Ordinary ideas about time and identity
over time become hopelessly compromised. The concept of probability
itself is brought into question. This picture of many branching
worlds is inchoate, it is a vision, an error. There are realist
alternatives to many worlds, some even that preserve the
Schrodinger equation unchanged.
Twenty specially written essays, accompanied by commentaries and
discussions, examine these claims and counterclaims in depth. They
focus first on the question of ontology, the existence of worlds
(Part 1 and 2), second on the interpretation of probability (Parts
3 and 4), and third on alternatives or additions to many worlds
(Parts 5 and 6). The introduction offers a helpful guide to the
arguments for the Everett interpretation, particularly as they have
been formulated in the last two decades.
