The development of nuclear weapons during the Manhattan Project is one of the most significant scientific events of the twentieth century. This revised and updated 3rd edition explores the challenges that faced the scientists and engineers of the Manhattan Project. It gives a clear introduction to fission weapons at the level of an upper-year undergraduate physics student by examining the details of nuclear reactions, their energy release, analytic and numerical models of the fission process, how critical masses can be estimated, (...) how fissile materials are produced, and what factors complicate bomb design. An extensive list of references and a number of exercises for self-study are included. Links are given to several freely-available spreadsheets which users can use to run many of the calculations for themselves. (shrink)

The development of atomic bombs under the auspices of the U.S. Army's Manhattan Project during World War II is considered to be the outstanding news story of the twentieth century. In this book, a physicist and expert on the history of the Project presents a comprehensive overview of this momentous achievement. The first three chapters cover the history of nuclear physics from the discovery of radioactivity to the discovery of fission, and would be ideal for instructors of a sophomore-level "Modern (...) Physics" course. Student-level exercises at the ends of the chapters are accompanied by answers. Chapter 7 covers the physics of first-generation fission weapons at a similar level, again accompanied by exercises and answers. For the interested layman and for non-science students and instructors, the book includes extensive qualitative material on the history, organization, implementation, and results of the Manhattan Project and the Hiroshima and Nagasaki bombing missions. The reader also learns about the legacy of the Project as reflected in the current world stockpiles of nuclear weapons. This second edition contains important revisions and additions, including a new chapter on the German atomic bomb program and new sections on British and Canadian contributions to the Manhattan project and on feed materials. Several other sections have been expanded; reader feedback has been helpful in introducing minor corrections and improved explanations; and, last but not least, the second edition includes a detailed index.

The three cycles of cell division immediately following theformation of the cellular blastoderm during Drosophila embryogenesis display an invariant pattern(1,2). Bursts of transcription of a gene called string are required and sufficient to trigger mitosis at this time during development(3). The activator of mitosis encoded by the string gene is a positive regulator of cdc2 kinase and a Drosophila homologue of the Saccharomyces pombe cdc25 tyrosine phosphatase(4,5). Evidence presented in a recent paper(6) demonstrates that transcription of string, and hence the (...) timing and pattern of mitosis in the postblastoderm embryo, is under complex developmental control. Several lines of evidence support this interpretation, including the analysis of string transcription in pattern formation mutants, cell cycle arrest mutants, and the preliminary characterization of an extensive cis‐acting regulatory region.

Charles Demuth is widely recognized as one of the most significant American modernists. His precisionist cityscapes, exquisite flowers, and free-wheeling watercolors of vaudeville performers, homosexual bathhouses, and cabaret scenes hang in many of the country's most prestigious collections, including the Metropolitan Museum of Art, the Philadelphia Museum of Art, the Columbus Museum of Art, the Amon Carter Museum in Fort Worth, the Art Institute of Chicago, and in Demuth's Lancaster, Pennsylvania, family residence, now home of the Demuth Foundation. At a (...) time when many American artists remained tied to Europe, Demuth "Americanized" European modernism. This collection of 155 of his letters offers valuable views of the arts and letters colonies in Provincetown, New York, and Paris. Besides offering information on Demuth's own works, the letters also shed light on the output of his contemporaries, as well as references to their trips, liaisons, and idiosyncrasies. Demuth numbered among his correspondents some of the most famous artists and writers of his time, inluding Georgia O'Keeffe, Eugene O'Neill, John Reed, Gertrude Stein, Alfred Stieglitz, Carl Van Vechten, and William Carlos Williams. In his travels in the United States and abroad, he encountered many other talented contemporaries: Peggy Bacon, Muriel Draper, Marcel Duchamp, the Stettheimer sisters, artists and writers, patrons, and gallery owners. Whether he is offering to pick up a copy of Joyce'sUlyssesfor Eugene O'Neill or trying to convince Georgia O'Keeffe to decorate his music room, Demuth is always in the thick of art and literary life. Flamboyant in attire but descreet in his homosexuality, Demuth also reveals in his letters the life of a talented homosexual in the teens and twenties. With his best friends Robert Locher and Marsden Hartley, he circulated through the art colonies of Greenwich Village, Provincetown, and Paris, meeting everyone. The book also contains reprints of some short appraisals of Demuth and his work that were published during his lifetime, long out of print, including pieces by A. E. Gallatin, Angela E. Hagen, Marsden Hartley, Helen Henderson, Henry McBride, Carl Van Vechten, Rita Wells, and Willard Huntington Wright. Author note:Bruce Kellneris Emeritus Professor of English, Millersville University, and a member of the Demuth Foundation Board of Directors. He is the author or editor of 10 other books. (shrink)

Thomas Reed argues that the Christian, if apprised of Plantinga's central claims in Warranted Christian Belief, should be agnostic regarding Christianity's central tenets. Reed models his argument on Plantinga's own argument against naturalism, according to which naturalists have a built-in defeater for their epistemology. Reed bases his argument on the contention that if Christian theism cannot be shown or demonstrated, rational Christians should refrain from believing. Not only does Reed's contention not follow, but he confuses logically possible defeaters with actual (...) defeaters and ignores Plantinga's claims regarding the Aquinas/Calvin model and the proper basicality of belief in God.

"In the 25 essays that comprise this grimly fascinating volume, Reed shines a light into some very dark corners. From its opening tale of South African baboons with a taste for human babies to a thoroughly icky account of a middle-aged woman's seduction of young boys, these are literary snapshots of the world at its worst."--Amazon.com.

Since the introduction of mathematical population genetics, its machinery has shaped our fundamental understanding of natural selection. Selection is taken to occur when differential fitnesses produce differential rates of reproductive success, where fitnesses are understood as parameters in a population genetics model. To understand selection is to understand what these parameter values measure and how differences in them lead to frequency changes. I argue that this traditional view is mistaken. The descriptions of natural selection rendered by population genetics models are (...) in general neither predictive nor explanatory and introduce avoidable conceptual confusions. I conclude that a correct understanding of natural selection requires explicitly causal models of reproductive success. *Received May 2006; revised December 2006. †To contact the author, please write to: Department of Philosophy, Kansas State University, 201 Dickens Hall, Manhattan, KS 66506; e‐mail: [email protected] .

The most successful theory in all of science--and the basis of one third of our economy--says the strangest things about the world and about us. Can you believe that physical reality is created by our observation of it? Physicists were forced to this conclusion, the quantum enigma, by what they observed in their laboratories. Trying to understand the atom, physicists built quantum mechanics and found, to their embarrassment, that their theory intimately connects consciousness with the physical world. Quantum Enigma explores (...) what that implies and why some founders of the theory became the foremost objectors to it. Schrodinger showed that it "absurdly" allowed a cat to be in a "superposition" simultaneously dead and alive. Einstein derided the theory's "spooky interactions." With Bell's Theorem, we now know Schrodinger's superpositions and Einstein's spooky interactions indeed exist. Authors Bruce Rosenblum and Fred Kuttner explain all of this in non-technical terms with help from some fanciful stories and bits about the theory's developers. They present the quantum mystery honestly, with an emphasis on what is and what is not speculation. Physics' encounter with consciousness is its skeleton in the closet. Because the authors open the closet and examine the skeleton, theirs is a controversial book. Quantum Enigma's description of the experimental quantum facts, and the quantum theory explaining them, is undisputed. Interpreting what it all means, however, is controversial. Every interpretation of quantum physics encounters consciousness. Rosenblum and Kuttner therefore turn to exploring consciousness itself--and encounter quantum physics. Free will and anthropic principles become crucial issues, and the connection of consciousness with the cosmos suggested by some leading quantum cosmologists is mind-blowing. Readers are brought to a boundary where the particular expertise of physicists is no longer a sure guide. They will find, instead, the facts and hints provided by quantum mechanics and the ability to speculate for themselves. (shrink)

This collection brings together previously unpublished works by well-known philosophers on the philosophy of action, the metaphysics of causality, and the philosophy of psychology. Nine of the essays directly discuss Donald Davidson's work on these topics, while three others challenge a Davidsonian approach through discussion of independent but related issues. These essays are followed by replies from Davidson, including a previously unpublished essay, "Adverbs of Action.".

According to recent commentators like Paul Guyer, Kant agrees with Hume's Dialogues Concerning Natural Religion that physico-theology can never provide knowledge of God and that the concept of God, nevertheless, provides a useful heuristic principle for scientific enquiry. This paper argues that Kant, far from agreeing with Hume, criticizes Hume's Dialogues for failing to prove that physico-theology can never yield knowledge of God and that Kant correctly views Hume's Dialogues as a threat to, rather than an anticipation of, his own (...) view that the concept of God provides a useful heuristic principle for science. The paper concludes that Kant's critique of physico-theology reflects Kant's deep dissatisfaction with Hume's manner of argumentation and suggests that Kant's attempt to provide a more successful critique of physico-theology merits continued philosophical attention.

Prabhpal Singh has recently defended a relational account of the difference in moral status between fetuses and newborns as a way of explaining why abortion is permissible and infanticide is not. He claims that only a newborn can stand in a parent–child relation, not a fetus, and this relation has a moral dimension that bestows moral value. We challenge Singh’s reasoning, arguing that the case he presents is unconvincing. We suggest that the parent–child relation is better understood as an extension (...) of an existing relationship formed during the gestational period. The change in this relation at birth is not sufficient to justify the radical change in moral status required to rule out infanticide while accepting the permissibility of abortion. Given that the moral status of orphans is also problematic under Singh’s account, we conclude that Singh has not shown that a newborn has greater moral worth than a fetus. (shrink)

The second edition of The Great Psychotherapy Debate has been updated and revised to include a history of healing practices, medicine, and psychotherapy, an expanded theoretical presentation of the contextual model, an examination of therapist effects, and a thorough review of the research on common factors such as the alliance, expectations, and empathy.

In this paper I investigate Socrates as a friend in Plato's 'Phaedo'. I begin by setting out his friends' request for reassurance of how they will fare after Socrates dies. I argue that by structuring the discussion as he does, Socrates provides one final opportunity for his friends to prepare themselves for life without him, thus offering them the best kind of reassurance they could ask for.

Four of the commentaries criticised my claim that assisted suicide for the terminally ill is discriminatory. 1 They were united in this judgement roughly because they insisted that assisted suicide is in fact a benefit and not a harm. I concede that if it is a benefit, then there is no way in which the terminally ill can be disadvantaged by it and hence no way it can be an instance of discrimination. I pointed out in the article that this (...) issue is controversial and could not be settled in my article, nor can it be settled in this brief response. Assisted suicide harms the terminally ill in several ways. First, it harms the people who do not adopt it by forcing them to defend their continued existence. Second, it harms many of the people who adopt it in so far as they are deprived of a life... (shrink)

I argue that Plato distinguishes between personal immortality and immortality of the soul. I begin by criticizing the consensus view that Plato identifies the person and the soul. I then turn to the issue of immortality. By considering passages from 'Symposium' and 'Timaeus', I make the case that Plato thinks that while the soul is immortal by nature, if a person is going to be immortal, they must become so. Finally, I argue that Plato has a psychological continuity approach to (...) personal identity. Thus, for Plato, a person becomes immortal by avoiding reincarnation and securing for themselves psychological continuity forever. (shrink)

Don Marquis’ future-like-ours account argues that abortion is seriously immoral because itdeprives the embryo or fetus of a valuable future much like our own. Marquis was mindful ofcontraception being reductio ad absurdum of his reasoning, and argued that prior tofertilisation, there is not an identifiable subject of harm. Contra Marquis, Tomer Chaffercontends that the ovum is a plausible subject of harm, and therefore contraception deprives theovum of a future-like-ours. In response, I argue that being an identifiable subject of harm is (...) notsufficient for Marquis’ argument to succeed. In addition, we must also share our identity withan ovum. I show that on the account of personal identity utilised by Marquis’ defenders, weare not identical with an ovum. As a result, Chaffer’s reductio fails. (shrink)

The Great Psychotherapy Debate: Models, Methods, and Findings comprehensively reviews the research on psychotherapy to dispute the commonly held view that the benefits of psychotherapy are derived from the specific ingredients contained in a given treatment (medical model). The author reviews the literature related to the absolute efficacy of psychotherapy, the relative efficacy of various treatments, the specificity of ingredients contained in established therapies, effects due to common factors, such as the working alliance, adherence and allegiance to the therapeutic protocol, (...) and effects that are produced by different therapists. In each case, the evidence convincingly corroborates the contextual model and disconfirms the prevailing medical model. (shrink)

This volume frames the question of responsibility as a problem of agency in relation to the systems and structures of globalization. According to Ricoeur responsibility is a “shattered concept” when considered too narrowly as a problem of act, agency and individual freedom. To examine this Esther Reed develops a short genealogy of modern liberal and post-liberal concepts of responsibility in order to understand better the relationship dominant modern framings of the meanings of responsibility. Reed engages with writings by major modern (...) (Schleiermacher, Hegel, Marx, Weber) and post-liberal (Buber, Levinas, Derrida, Badiou, Butler, Young, Critchley) theorists to illustrate the shift from an ethnic responsibility built on notions of accountability and attributions to an ethic responsibility that starts variously from the 'other'. Reed sees Dietrich Bonhoeffer as the most promising partner of this theological dialogue, as his learning of responsibility from the risen Christ present now in the (global) church is a welcome provocation to new thinking about the meaning of responsibility learned from land, distant neighbour, (global) church and the bible. Bonhoeffer's reflections on the centre, boundaries and limits of responsibility remain helpful to Christian people struggling with an increasingly exhausted concept of accountability. (shrink)

This highly original history of ideas considers the impact of Hegel on French philosophy from the 1920s to the present. As Baugh's lucid narrative makes clear, Hegel's influence on French philosophy has been profound, and can be traced through all the major intellectual movements and thinkers in France throughout the 20th Century from Jean Wahl, Sartre, and Bataille to Foucault, Deleuze, and Derrida. Baugh focuses on Hegel's idea of the "unhappy consciousness," and provides a bold new account of Hegel's early (...) reception in French intellectual history. (shrink)

In this paper, we present a survey of the development of the technique of argument diagramming covering not only the fields in which it originated - informal logic, argumentation theory, evidence law and legal reasoning – but also more recent work in applying and developing it in computer science and artificial intelligence. Beginning with a simple example of an everyday argument, we present an analysis of it visualised as an argument diagram constructed using a software tool. In the context of (...) a brief history of the development of diagramming, it is then shown how argument diagrams have been used to analyze and work with argumentation in law, philosophy and artificial intelligence.

It is a truism that where one starts from and the direction one goes determines where one ends up. This is no less true in philosophy than elsewhere, and certainly no less true in matters dealing with the relationship between God’s foreknowledge and human free actions.

As the applied field of social work attempts to become more of a sciencebased profession, it is relying more on the findings from empirical research studies. Withinsocial work there is little discussion of the philosophy of science underlying conventional research inquiry. This paper introduces some major philosophical principles that undergird scientific investigations of the causes of societal and psychosocial problems and of the effectiveness of structured programs, policies and practices to ameliorate social ills. Among the principles introduced are the philosophical (...) concepts of determinism, empiricism, realism, operationalism, scientific materialism, parsimony, logic, and positivism. Together these philosophical assumptions provide a pragmatic framework to design and conduct scientific research of value to the social work profession and other fields. (shrink)

Ranging from Joseph Bellamy to Hilary Putnam, and from early New England Divinity Schools to contemporary university philosophy departments, historian Bruce Kuklick recounts the story of the growth of philosophical thinking in the United States. Readers will explore the thought of early American philosphers such as Jonathan Edwards and John Witherspoon and will see how the political ideas of Benjamin Franklin, Thomas Paine and Thomas Jefferson influenced philosophy in colonial America. Kuklick discusses The Transcendental Club (members Henry David Thoreau, (...) Ralph Waldo Emerson) and describes the rise of pragmatism centered on Metaphysical Club of Cambridge (and members William James, Oliver Wendell Holmes, and Charles Peirce). He examines the profound impact Darwinism had on American philosophy and looks at Idealists such as the Kantian Josiah Royce and the Hegelian John Dewey. The book shows how, in the twentieth century, the Nazi conquest of Europe unleashed a flood of European intellectuals onto these shores, including such major thinkers as Theodore Adorno, Erich Fromm, Rudolph Carnap, and Alfred Tarski. Finally, Kuklick examines the contributions of such contemporary philosophers as Sidney Hook and Willard Quine and such books as John Rawl's A Theory of Justice and Herbert Marcuse's One Dimensional Man. Kuklick pulls no punches in portraying the state of American philosophy today and its contested role in the intellectual life of the nation and the world. The range of philosophical thought in our nation's history has been great, from Edwards's Religious Affections to Kuhn's The Structure of Scientific Revolutions, and Bruce Kuklick has captured it all in a book that blends intricate details with sweeping vision.

People are unable to report how they decide whether to move backwards or forwards to catch a ball. When asked to imagine how their angle of elevation of gaze would change when they caught a ball, most people are unable to describe what happens although their interception strategy is based on controlling changes in this angle. Just after catching a ball, many people are unable to recognise a description of how their angle of gaze changed during the catch. Some people (...) confidently choose incorrect descriptions that would guarantee failure of interception demonstrating unconscious knowledge co-existing with systematically different conscious beliefs. Where simple solutions to important evolutionary problems exist, unconscious perception needs to be impervious to conscious beliefs. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Philosophy, Dissent, and Nonconformity, 1689–1920Bruce KuklickAlan P. F. Sell. Philosophy, Dissent, and Nonconformity, 1689–1920. Cambridge: James Clark & Co., 2004. Pp. 296. Cloth, £50.00This is a competent, clearly written, and authoritative exploration of its topic, in some respects a labor of love, for the author is both a pastor and a student of theology. Sell comprehensively examines the proliferation of dissenting academies and nonconformist colleges of England and (...) Wales, with some excursions into the Scottish scene, from the Toleration Act of 1689 through the early twentieth century. For the 230 years of this study, a great variety of schools, many of which had only a brief moment of existence, and most of which were barely funded, offered training for the ministers of over a dozen protestant denominations in Britain. Often one man provided instruction in subjects as diverse as mathematics, science, and literature—as well as religious fields.Sell does not focus on ministerial training or even theology, but the way in which the nonconforming religious élite expounded on and was taught philosophy. Thus, one sees how a diverse group that surely had sectarian needs in mind was also interested in grasping how thinkers outside its belief system approached basic problems of human existence. Over time Descartes and other continental rationalists, Locke and the Cambridge Platonists, Kant and Hegel, and the nineteenth-century British idealists were taught by the dissenting professoriate. In summarizing its interpretation, Sell presents a history of modern Anglo-European philosophy as it was refracted in the minds of (some) English-speaking Protestants. Their emphases are not unexpected: empiricism is somewhat devalued, and rationalistic and a priori modes of thinking perhaps inflated. The ethical implications of epistemology and metaphysics are most carefully explicated, and what is taken to be most strategic for [End Page 211] Reformed theology is underscored. Overall, if one is tempted to generalize (as Sell himself does not), the positions reached are credible and not out of line with the philosophical cutting edge of each era.For the most part the dissenters were not themselves creative philosophers of the first rank, but Sell rightly puts forward (206) a short list of thinkers at these schools who have genuine claims to merit, and my own very short list would include Richard Price, James Martineau, and Robert Mackintosh.The author uses diverse strategies to give readers a sense of the effort of these mostly forgotten men. To some extent the book is a biographical compendium, with brief sections on individual or paired thinkers. But Sell also offers coverage by denomination, and he adds a series of discussions by topics—on an assortment of recurring dilemmas in moral philosophy and on apologetics. A final and most useful feature of the book is a trio of indices, in addition to the very full notes and a complete bibliography, mainly of the writings of the many authors cited. Two of the indices are standard, but helpful, lists of persons and topics; the third one is a compendium of all the academies Sell treats, as well as their denominational affiliation, and the duration of their existences.Philosophy, Dissent, and Nonconformity has the defects of its virtues. It is encyclopedic in nature, available for reference but unlikely to be read as a synthetic book, except by devotees of a certain kind of historical philosophical theology. The author also presumes his readers are unlikely to tackle the volume unless they have a prior attraction. That is, the book is written without much contextual explication, and attention to the needs of the non-specialist certainly would have made the volume of wider interest. The work is still relatively brief, under 300 pages, and because of its character, I would have liked to have seen a series of maps that pinpointed the whereabouts of the dissenting schools, giving the reader a visual sense of when and where they arose and declined among particular denominations, and that informed us of what the relations were among the successive professors who defined the learning.Bruce KuklickUniversity of PennsylvaniaCopyright © 2005 Journal of the History of Philosophy, Inc....
