“In this article we sketch out the landscape for this Special Issue on anticipating and embedding the societal challenge of nanotechnologies. Tools that actors may choose to employ for these processes are articulated, and further explored through the introduction of the seven articles which comprise this Issue. Taken together, these articles create a cogent narrative on the societal challenges posed by nanotechnologies. They are drawn together by three distinct themes, each of which is briefly considered within this context of this (...) Introductory article”. (shrink)

G. G. Stokes and Lord Kelvin helped bring about conceptual and institutional changes that transformed the science of physics. Indeed, they and their Victorian colleagues constituted one of the most significant groups of scientists in the whole history of science. This collection of letters was first published in 1990, and provides, therefore, invaluable insight and information for a period of major historical importance. Stokes and Kelvin corresponded for over fifty years as professors in Cambridge and Glasgow, respectively, thus (...) amassing what is easily the largest extant correspondence between two Victorian physicists. The letters range widely over the people, ideas, and institutions of the age. They illuminate the histories of Cambridge and Glasgow Universities and the Royal Society of London, for example, as well as developments in electromagnetism, hydrodynamics, elasticity, optics, and X-rays. The editor's introduction describes the context of the pair's careers, while guiding the reader into their correspondence. (shrink)

This volume is about the many ways we perceive. Contributors explore the nature of the individual senses, how and what they tell us about the world, and how they interrelate. They consider how the senses extract perceptual content from receptoral information. They consider what kinds of objects we perceive and whether multiple senses ever perceive a single event. They consider how many senses we have, what makes one sense distinct from another, and whether and why distinguishing senses may be useful. (...) They consider the extent to which the senses act in concert, rather than as discrete modalities, and whether this influence is epistemically pernicious, neutral, or beneficial. They explore both the familiar five sense modalities and other candidate sense modalities, including a sense for flavour, inner senses (e.g., a sense for pain), and various senses that may result from using sensory substitution devices. Contributors often represent competing views, and the methods they deploy sometimes differ from one essay to the next—with some drawing upon the sciences and engineering and others relying upon conceptual analysis. All contributors agree, nonetheless, that traditional theorizing about the senses is hampered by a neglect of the senses other than vision, and by the misconception that vision is a passive receptacle for an image thrown by a lens. And many contributors believe that it is unduly restrictive to think of perception as a collation of contents provided by individual sense modalities; they think that to understand perception properly, we need to build into our accounts the idea that the senses work together. The ambition of the volume is to begin to develop better paradigms for understanding the senses, and thereby to move toward a better understanding of perception. (shrink)

Vision often dominates other perceptual modalities both at the level of experience and at the level of judgment. In the well-known McGurk effect, for example, one’s auditory experience is consistent with the visual stimuli but not the auditory stimuli, and naïve subjects’ judgments follow their experience. Structurally similar effects occur for other modalities (e.g. rubber hand illusions). Given the robustness of this visual dominance, one might not be surprised that visual imagery often dominates imagery in other modalities. One might be (...) surprised, however, that visual imagery often dominates perception in other modalities. This more controversial claim is motivated both by empirical data and by introspection. Some think of perception-perception visual dominance as epistemically good, holding that cases in which visual dominance misleads us (e.g. McGurk and rubber hand illusions) are cases in which the perceptual system resolves conflicts according to principles that are generally reliable. Here, we explore support for the more controversial claim that imagery-perception visual dominance is epistemically good. We suggest that, when the task is richly spatial, requiring for optimal performance the all-at-once identification of macro-spatial and allocentric properties (e.g. identifying the shape or location of a felt or heard object), the visual, whether perception or imagination, should dominate other modalities. Put another way, when identifying objects, one should go and look or, short of that, visually imagine candidate objects, and then follow the visual, even against conflicting perceptions from other modalities. For this broadly-typed category of of cognitive-perceptual task, vision does dominate and it should. (shrink)

Philosophers of mind and cognitive scientists have recently taken renewed interest in cognitive penetration, in particular, in the cognitive penetration of perceptual experience. The question is whether cognitive states like belief influence perceptual experience in some important way. Since the possible phenomenon is an empirical one, the strategy for analysis has, predictably, proceeded as follows: define the phenomenon and then, definition in hand, interpret various psychological data. However, different theorists offer different and apparently inconsistent definitions. And so in addition to (...) the usual problems (e.g., definitions being challenged by counterexample), an important result is that different theorists apply their definitions and accordingly get conflicting answers to the question “Is this a genuine case of cognitive penetration?”. This hurdle to philosophical and scientific progress can be remedied, I argue, by returning attention to the alleged consequences of the possible phenomenon. There are three: theory-ladenness of perception in contexts of scientific theory choice, a threat to the general epistemic role of perception, and implications for mental architecture. Any attempt to characterize or define, and then empirically test for, cognitive penetration should be constrained by these consequences. This is a method for interpreting and acquiring experimental data in a way that is agreeable to both sides of the cognitive penetration debate. Put crudely, the question shifts to “Is this a cognitive-perceptual relation that results in (or constitutes) one or more of the relevant consequences?” In answering this question, relative to various data, it may turn out that there is no single unified phenomenon of cognitive penetration. But this should be no matter, since it is the consequences that are of central importance to philosophers and scientists alike. (shrink)

This paper, using the author's decomposition method and recent generalizations, presents algorithms for an analytic solution of the stochastic Navier-Stokes system without linearization, perturbation, discretization, or restrictive assumptions on the nature of stochasticity. The pressure, forces, velocities, and initial/boundary conditions can be stochastic processes and are not limited to white noise. Solutions obtained are physically realistic because of the avoidance of assumptions made purely for mathematical tractability by usual methods. Certain extensions and further generalizations of the decomposition method have (...) provided the basis for the solution. (shrink)

It may seem odd to review a New York social club's yearbook, with its list of members’ addresses and series of committee reports. But such books sometimes contain material of more general interest. The latest one from the Century Association, for example, devotes 250 of its 685 pages to “Century Memorials”—that is, biographical sketches of recently deceased members, written by other members. Among the well-known figures taken up in these eighty-three sketches are the artists Richard Anuszkiewicz and Robert Motherwell; the (...) architects Henry N. Cobb and Charles A. Platt; the newspaper editors Harold Evans and Whitelaw Reid; the historians Henry F. Graff and William McFeely; the translator and literary scholar Donald Keene; the collector of literary and musical manuscripts Frederick Koch; the popular writer on Russian history Robert K. Massie; the clergyman James Parks Morton; the financier Felix G. Rohatyn; the lawyers Whitney North Seymour Jr. and Isaac N. Phelps Stokes; the literary editor Elisabeth Sifton; the university president Michael Sovern; the museum director Evan H. Turner; and the broadcast journalist Sander Vanocur. The sketches are generally well written and often richly evocative: the writers include Louis Begley, Kenneth T. Jackson, D. T. Max, and Honor Moore.The long shelf of Century volumes like this one clearly constitutes a valuable contribution to prosopographical literature. And the Century is not the only institution with such a tradition (other examples are the British Academy and the American Philosophical Society); but their publications are a frequently overlooked source, one not always available in research libraries. Unfortunately, it is also a source that seems to be diminishing: the American Antiquarian Society and the John Simon Guggenheim Memorial Foundation are examples of organizations, each with a history of providing biographical information, that are no longer doing so. Of course, the great previous runs of the former's Proceedings and the latter's Reports remain (one hopes) on the shelves for those who know to look for them. A step in the opposite direction has recently been taken by the Grolier Club, which has not had such a tradition (except for two biographical volumes in 1959 and 2000): its Gazette now includes a section of memorials in each issue. This is a welcome move, but one has to regret that so little scholarly use is made of this whole body of biographical detail and reminiscence. (shrink)

The concept of similar systems arose in physics, and appears to have originated with Newton in the seventeenth century. This chapter provides a critical history of the concept of physically similar systems, the twentieth century concept into which it developed. The concept was used in the nineteenth century in various fields of engineering, theoretical physics and theoretical and experimental hydrodynamics. In 1914, it was articulated in terms of ideas developed in the eighteenth century and used in nineteenth century mathematics and (...) mechanics: equations, functions and dimensional analysis. The terminology physically similar systems was proposed for this new characterization of similar systems by the physicist Edgar Buckingham. Related work by Vaschy, Bertrand, and Riabouchinsky had appeared by then. The concept is very powerful in studying physical phenomena both theoretically and experimentally. As it is not currently part of the core curricula of STEM disciplines or philosophy of science, it is not as well known as it ought to be. (shrink)

Im Zentrum des vorliegenden Sammelbandes steht die Frage nach dem Bösen in Religionen, die als monotheistisch verstanden werden oder für die zumindest die Herrschaft des Hauptgottes über alle anderen Götter und Mächte ein entscheidendes Anliegen ist. Der Schwerpunkt liegt auf dem sich formierenden Judentum und Christentum sowie dem Alten Testament. Besonderes Interesse gilt den Texten aus Qumran, und darüber hinaus erfolgt ein Blick auf mittelalterliche Heiligenlegenden. Die Beiträge des Bandes zeigen, dass es in den antiken jüdischen und christlichen Texte eine (...) große Vielfalt von Verkörperungen des Bösen gibt, sei es extern als Dämon oder Teufel, sei es intern als die menschliche Fähigkeit, Böses zu tun. Außerdem stellt sich heraus, dass in der jüdisch-christlichen Literatur Dualismus nicht grundsätzlich abgelehnt wird, aber nur Formen von Dualismus vorkommen, in denen das Böse Gott und dem Guten letztlich untergeordnet ist. Mit Beiträgen von: Jörn Bockmann, Miryam T. Brand, Jan Dochhorn, Matthew Goff, Erkki Koskenniemi, Michael Morris, Hector M. Patmore, Susanne Rudnig-Zelt, Markus Saur, Ryan E.

The phenomena, molecular path in a liquid or a gas, fluctuating price stoke, fission and fusion, quantum field theory, relativistic wave motion, etc., are modeled through the nonlinear time fractional clannish random Walker’s parabolic equation, nonlinear time fractional SharmaTassoOlver equation, and the nonlinear space-time fractional KleinGordon equation. The fractional derivative is described in the sense of conformable derivative. From there, the G ′ / G, 1 / G -expansion method is found to be ensuing, effective, and capable to provide functional (...) solutions to nonlinear models concerning physical and engineering problems. In this study, an extension of the G ′ / G, 1 / G -expansion method has been introduced. This enhancement establishes broad-ranging and adequate fresh solutions. In addition, some existing solutions attainable in the literature also confirm the validity of the suggested extension. We believe that the extension might be added to the literature as a reliable and efficient technique to examine a wide variety of nonlinear fractional systems with parameters including solitary and periodic wave solutions to nonlinear FDEs.

Expertise is a cognitive achievement that clearly involves experience and learning, and often requires explicit, time-consuming training specific to the relevant domain. It is also intuitive that this kind of achievement is, in a rich sense, genuinely perceptual. Many experts—be they radiologists, bird watchers, or fingerprint examiners—are better perceivers in the domain(s) of their expertise. The goal of this paper is to motivate three related claims, by substantial appeal to recent empirical research on perceptual expertise: Perceptual expertise is genuinely perceptual (...) and genuinely cognitive, and this phenomenon reveals how we can become epistemically better perceivers. These claims are defended against sceptical opponents that deny significant top-down or cognitive effects on perception, and opponents who maintain that any such effects on perception are epistemically pernicious.

Both common sense and dominant traditions in art criticism and philosophical aesthetics have it that aesthetic features or properties are perceived. However, there is a cast of reasons to be sceptical of the thesis. This paper defends the thesis—that aesthetic properties are sometimes represented in perceptual experience—against one of those sceptical opponents. That opponent maintains that perception represents only low-level properties, and since all theorists agree that aesthetic properties are not low-level properties, perception does not represent aesthetic properties. I offer (...) a novel argument—what I call the argument from seeing-as—against that sceptic which moves from consideration of ambiguous figures to consideration of visual art. It concludes that aesthetic properties are sometimes perceived and delivers a general lesson for philosophy of perception. Contrary to extant theories of rich perceptual content, aesthetic properties are far better candidates for high-level perceptual contents than standardly theorized rich contents like natural kinds.
