This paper focuses on the base of awareness as space and light.

The inaugural collection in an exciting new exchange between philosophers and geographers, this volume provides interdisciplinary approaches to the environment as space, place, and idea. Never before have philosophers and geographers approached each other's subjects in such a strong spirit of mutual understanding. The result is a concrete exploration of the human-nature relationship that embraces strong normative approaches to environmental problems.

MATTER AND LIGHT The New Physics By LOUIS DE BROGLIE. Originally published in 1937. TRANSLATORS NOTE: THE Author has in certain places modified the original French text for the English translation, for the sake of greater cohesion, and has also revised some passages, in order to bring them into accord with the results of later research. Occasional Translators Notes are shown in square brackets. The chapter on The Undulatory Aspects of the Electron has the special historical interest of having (...) been delivered as a Lecture on the occasion of the Authors receipt of the Nobel Award, while that on Wave Mechanics and its Interpretations was given as an Address at the Glasgow meeting of the British Association in 1928. I am indebted to Dr. J. E. Turner, of the University of Liver pool, for assistance with the translation and the proofs, and to Dr. C. Strachan, of the same University, I am indebted for valuable assistance in dealing with the equations and the more technical passages, as well as for reading the proofs. W. H. J. PREFACE: THE amiable insistence of my friend Andr George has induced me to collect in the present Volume a number of Studies on con temporary Physics written from both the general and the more metaphysical point of view. Each of these Studies forms an inde pendent whole, and can be read by itself. A slight degree of repeti tion which the reader is asked to overlook has been the inevi table result for on more than one occasion I have been compelled to duplicate a summary of the great fundamental stages of con temporary Physics, such as the classification of simple substances, the investigation of the photo-electric effect and the origin of the Theory of Light Quanta and of Wave Mechanics the subjects are somewhat technical, and I cannot well assume that they are common knowledge. But though the same subject is outlined in several of these Studies, I have tried to take up a different point of view in each, and have endeavoured to throw light on different aspects of the essential problems of Quantum Physics in order to facilitate a grasp of their importance. On comparing the different chapters the reader will observe that, while overlapping, they also complement one another and he will feel the fascination and greatness inherent in the vast structure of modern Physics. And while admiring the vast number and the extreme delicacy of experimental facts which laboratory physicists have succeeded in revealing, and the strange and brilliant concepts devised by theorists to explain them, he will appreciate to what a degree the methods and ideas of physicists have grown in subtlety during recent years, and how great has been the progress from the somewhat ingenuous Realism and the over-simplified Mechanics of earlier thinkers. The more deeply we descend into the minutest structures of Matter, the more clearly we see that the concepts evolved by the mind in the course of everyday experience especially those of Time and Space must fail us in an endeavour to describe the new worlds which we are entering. One feels tempted to say that the outlines of our concepts must undergo a progressive blurring, in order that they may retain some semblance of relevance to the realities of the subatomic scales. Time and Space, in other words, are too loose a dress for the elementary entities individuality becomes attenuated in the mysterious pro cesses of interaction, and even Determinism, the darling of an older generation of physicists, is forced to yield...

Kedrov has reminded us that the development of knowledge proceeds from appearance to essence. That was also true of the development of notions about space and time. Leibniz, for example, defined space as the order of things existing at the same time. However, that definition is rather superficial, and it is only the development of physics, specifically relativity theory, which made it possible to penetrate more deeply into the nature of space and time and to ascribe a (...) precise and mathematically expressible notion to the well-known judgment to the effect that space and time are forms of the existence of matter.

This book addresses the social, functional and symbolic dimensions of urban space in today’s world. The twelve essays range from a conceptual framing of the issues to case descriptions, rich with illustrations. Together they provide a thorough exploration of the nature and significance of social space and particular aspects of its distribution in today’s urban spaces and the various factors that are competing for it. -/- The book addresses a topic that is intrinsically interdisciplinary. Questions of space (...) are examined from a rich variety of perspectives from urban planning to political philosophy, shedding some light on this shadowy process. Some of the issues addressed include the dichotomies of public and private space, rights and duties regarding the use of space, and conflicts over its allocation. Well-reasoned and lively discussions are offered from the perspective of basic values and rights. The recognition of the specifics of (minority community) identity as an institutional policy is raised in opposition to “abstract distributive accounts of justice” – economic pressures by developers and would-be gentrifiers.

_Time, Space, and Phantasy_ examines the connections between time, space, phantasy and sexuality in clinical practice. It explores the subtleties of the encounter between patient and analyst, addressing how aspects of the patient’s unconscious past are actualised in the present, producing new meanings that can be re-translated to the past. Perelberg’s analysis of Freud’s Multi-dimensional model of temporality suggests that he always viewed the constitution of the individual as non-linear. In Freud’s formulations, the individual is decentred and ruled (...) by different temporalities, most of which escape their consciousness. Perelberg identifies the similarities between this and Einstein’s theory of relativity which states that rather than being absolute, time depends on the relative position and speed of the observing individual suggesting that rather than being a reality, time is an abstraction, connecting objects and events. Throughout this text, Perelberg draws together connections between time, mental space, and phantasy showing how time is constantly reshaped in the light of new events and experiences. This book will be of interest to psychoanalysts, psychotherapists, psychologists, and social workers. (shrink)

This article analyses the multimodal representations of public space in Chilean broadcast news reports on the figure of the hooded rioter and its alleged connections with the student movement. We seek to identify how space is constructed as a legitimation strategy in relation to the actors involved and the actions taking place across four different news broadcast pieces in the light of Multimodal Critical Discourse Analysis and Systemic Functional Linguistics. Results show that the multimodal representations of (...) class='Hi'>space are crucial to identify and functionalize hooded rioters as belonging to the student movement. Actions are dependent on the spaces in which actors operate, restricting the occupation of certain spaces to specific actors. Thus, transgressive protest actions are to be contained to educational spaces and represented as naturalized vandalism, ignoring the students’/demonstrators’ motivations to recuperate/vindicate the public space.

Among the dubious theses "proved" by the author of this classic example of pseudo-scientific literature are: relativistic physics is incorrect, the quantum theory is incorrect, "the success of quantum theory is purely mathematical," time, like space, has three dimensions, inductance and mass are equivalent, there is such a thing as absolute motion, and "All properties which are possessed by either space or time individually are.... properties of both space and time." What makes this book unusual is the (...) fact that the immense number of citations and footnotes refer to almost all of the important books and articles in the field of the philosophical foundations of physics. Larson therefore has accomplished one outstanding task: he has succeeded in immersing himself in some of the most philosophically and scientifically compelling literature of recent times and has emerged unscathed by a single intelligible idea.—H.

Philosophers and geographers have converged on the topic of public space, fascinated and in many ways alarmed by fundamental changes in the way post-industrial societies produce space for public use, and in the way citizens of these same societies perceive and constitute themselves as a public. This volume advances this inquiry, making extensive use of political and social theory, while drawing intimate connections between political principles, social processes, and the commonplaces of our everyday environments.

Although the name of Immanuel Kant has survived in the history of culture as the name of one of the greatest philosophers of modern times, Kant's role as a scientist is also very important. His work in the field of cosmology and physics is directly related to philosophy. Kant's development of the transcendental method was a direct result of thinking about the relationship between mathematics and experiment. Transcendentalism and Kant's theory of subjectivity continue the development of physics from Galileo to (...) Newton and Leibniz. This is especially true of his theory of space and time. All this should have turned transcendental aesthetics into a turning point in the development of mathematical natural science. However, in practice, the alienation of the natural sciences from philosophy has only intensified. An analysis of the scientific revolution at the beginning of the 20th century shows the enormous role of Kant's ideas in it in repulsing scientists from Kantianism. Weinert, a researcher of the relationship of 20th century physics to Kant's philosophy, shows that Einstein, being a Kantian as a philosopher, opposed Kantianism as a physicist. He enthusiastically accepted the Kantian idea of the autonomy of theoretical knowledge, but did not accept the concept a priori. An approach in which experience and theory do not precede each other, but are in constant interaction, is defined in the article as experimental transcendentalism. With the methodological difference between physics and philosophy, the concept of space and time in modern physics has a deep similarity with the transcendental doctrine. The definition of the qualitative structure of space (Analysis Situs), including the theoretical substantiation of its three dimensions, was the subject of reflections of scientists from Galileo, Leibniz and Kant to Einstein and Poincaré.

Taking as its point of departure the question of light vis-à-vis the question of being in Derrida's work, this article discusses Derrida's radical conceptions of khoral spatiality and alterity, by linking his first book on Edmund Husserl's “The Origin of Geometry” and his early critique of Emmanuel Levinas to his exploration of the ethico-political problematics, in part, again, via Levinas, in his latest works. The article also considers Derrida's reading of Kafka in “Before the Law,” decisive for his analysis (...) of the problematics in question and for our understanding of the relationships between “geometry and democracy.” These relationships, the article argues, are an essential concern of much of Derrida's work and of our culture, from the pre-Socratics on.

This paper revisits the life of Adolf Lindenbaum in light of new research findings, then looks at two areas among many—metric spaces, and decompositions of point sets—where his work has been underappreciated.

Kant claims that we cannot cognize the mutual interaction of substances without their being in space; he also claims that we cannot cognize a ‘spatial community’ among substances without their being in mutual interaction. I situate these theses in their historical context and consider Kant’s reasons for accepting them. I argue that they rest on commitments regarding the metaphysical grounding of, first, the possibility of mutual interaction among substances-as-appearances and, second, the actuality of specific distance-relations among such substances. By (...) illuminating these commitments, I shed light on Kant’s metaphysics of space and its relation to Newton and Leibniz’s views. (shrink)

A growing literature testifies to the persistence of place as an incorrigible aspect of human experience, identity, and morality. Place is a common ground for thought and action, a community of experienced particulars that avoids solipsism and universalism. It draws us into the philosophy of the ordinary, into familiarity as a form of knowledge, into the wisdom of proximity. Each of these essays offers a philosophy of place, and reminds us that such philosophies ultimately decide how we make, use, and (...) understand places, whether as accidents, instruments, or fields of care.

This collection focuses on the ontology of space and time. It is centred on the idea that the issues typically encountered in this area must be tackled from a multifarious perspective, paying attention to both a priori and a posteriori considerations. Several experts in this area contribute to this volume: G. Landini discusses how Russell’s conception of time features in his general philosophical perspective;D. Dieks proposes a middle course between substantivalist and relationist accounts of space-time;P. Graziani argues that (...) it is necessary to provide an account of the “synthetic procedures” implicit in the recourse to diagrams in Euclid’s Elements, while E. Mares comes to the conclusion that in Euclid’s Elements we should treat the parallel postulate as empirical and the postulate that space is continuous as a priori. M. Arsenijevi?/M. Adži? present an important formal result concerning two theories of the infinite two-dimensional continua, which sheds new light on the current dispute between gunkologists and pointilists; F. Orilia discusses two problems for presentism, one regarding the duration of the present and the other related to Zeno’s paradoxes. A. Iacona delves deep into logical matters by focusing on the so-called T×W modal frames in order to deal with the deteterminism-indeterminism controversy. D. Mancuso outlines a non-standard temporal model compatible with time travel, andV. Fano/G. Macchia discuss time travels in the light of an important foundational principle of modern cosmology, Weyl’s Principle. (shrink)

Art interprets the visible world, physics charts its unseen workings--making the two realms seem completely opposed. But in Art & Physics, Leonard Shlain tracks their breakthroughs side by side throughout history to reveal an astonishing correlation of visions. From teh classical Greek sculptors to Andy Warhol and Jasper Johns, and from Aristotle to Einstein, aritsts have foreshadowed the discoveries of scientists, such as when Money and Cezanne intuited the coming upheaval in physics that Einstein would initiate. In this lively and (...) colorful narrative, Leonard Shlain explores how artistic breakthroughs could have prefigured the visionary insights of physicists on so many occasions throughtout history. Provacative and original, Art & Physics is a seamless integration of the romance of art and the drama of science...and exhilarating history of ideas. (shrink)

We discuss the hints for the disappearance of continuum space and time at microscopic scale. These include arguments for a discrete nature of them or for a fundamental non-locality, in a quantum theory of gravity. We discuss how these ideas are realized in specific quantum gravity approaches. Turning then the problem around, we consider the emergence of continuum space and time from the collective behaviour of discrete, pre-geometric atoms of quantum space, and for understanding spacetime as a (...) kind of “condensate”, and we present the case for this emergence process being the result of a phase transition, dubbed “geometrogenesis”. We discuss some conceptual issues of this scenario and of the idea of emergent spacetime in general. As a concrete example, we outline the GFT framework for quantum gravity, and illustrate a tentative procedure for the emergence of spacetime in this framework. Last, we re-examine the conceptual issues raised by the emergent spacetime scenario in light of this concrete example. (shrink)

What can we say of space and time when we consider them as attributes of nature and as attributes of nature in the context of experience? The following is an examination of this question in the light of those portions of the writings of Locke and Kant which were concerned with it. Since men have no difficulty in speaking about and utilizing the familiar spatial and temporal relations of things, we begin with these and shall avoid definition and (...) debate except insofar as it is pertinent to the present inquiry. Nor shall we consider it necessary to examine space and time in any other context as, for example, that of modern physics. The familiar world is the necessary condition for the conception of any intellectual development of it, and to begin with the intellectual development is to render it unintelligible. This is evidenced in several ways. When we begin with physics and mathematics, we cannot account for the world within which we live and consequently end in scepticism about it, whereas this is not the case when we begin with the actual world itself. Furthermore, the manifestly perceptible is indispensible to scientific enquiry for we must employ instruments and objects directly accessible to experience. Without these there would be neither experiment, observation nor inference. Communication would be impossible without it as well as discussion about subject matters such as logic and esthetics. It is for these reasons, therefore, that we begin with the familiar spatial and temporal relations of things. (shrink)

The collection of papers that comprise this thesis explore three sets of questions important to environmental philosophy, broadly construed. All three topics are explored through the theoretical device of environmental pragmatism, the argument that philosophical disagreements on environmental questions can sometimes be set aside in order to achieve compatible strategies to work toward improving environmental conditions. As part of this strategy, pragmatists also call for the abandonment of the existing prejudices of environmental philosophy, in particular nonanthropocentrism and commitments to moral (...) monism. Part I of the thesis looks at two sets of debates in environmental philosophy: the social ecology-deep ecology divide in political ecology, and the debate between monists and pluralists in environmental ethics. Both debates are used as a vehicle to advance the pragmatist position, as well as demonstrate the connection between this thesis and other attempts to articulate a workable form of pluralism in environmental philosophy. Next, the first half of Part II uses the pragmatist premise to launch applied investigations of two environmental questions: the privatization of environmental regulations, and the political appropriation of restoration ecology. The second half of Part II explores questions concerning urban space and political identity, which come to the center of environmental philosophy following a pragmatist assault on its existing prejudices. Finally, Part III continues the themes of the last half of Part II to look at issues concerning technology and built space, topics which have traditionally been ignored by environmental philosophers. These final chapters present a set of issues concerning space and place which must be integral to an environmental philosophy which has been tempered by pragmatic concerns. (shrink)

This concise book introduces nonphysicists to the core philosophical issues surrounding the nature and structure of space and time, and is also an ideal resource for physicists interested in the conceptual foundations of space-time theory. Tim Maudlin's broad historical overview examines Aristotelian and Newtonian accounts of space and time, and traces how Galileo's conceptions of relativity and space-time led to Einstein's special and general theories of relativity. Maudlin explains special relativity using a geometrical approach, emphasizing intrinsic (...) space-time structure rather than coordinate systems or reference frames. He gives readers enough detail about special relativity to solve concrete physical problems while presenting general relativity in a more qualitative way, with an informative discussion of the geometrization of gravity, the bending of light, and black holes. Additional topics include the Twins Paradox, the physical aspects of the Lorentz-FitzGerald contraction, the constancy of the speed of light, time travel, the direction of time, and more.Introduces nonphysicists to the philosophical foundations of space-time theory Provides a broad historical overview, from Aristotle to Einstein Explains special relativity geometrically, emphasizing the intrinsic structure of space-time Covers the Twins Paradox, Galilean relativity, time travel, and more Requires only basic algebra and no formal knowledge of physics.

In this paper I consider the relationship between the spatial properties of visual perceptual experience and the sense-datum inference. I argue that the sense datum inference should be accepted if spatial properties are not merely intentionally present in such experiences. This result serves to underline the seriousness of the difficulties that are presented to direct realism by a particular class of illusory spatial experiences based on the geometry of visual perceptual experience. In light of these considerations I argue that (...) it is a constraint on direct realism that the underlying spatial character of visual perceptual experiences must be the same as that of the physical world.

Sounds are heard, sometimes even felt, but in most cases they remain unseen. This ephemeral and invisible nature of sound was already considered a problem when the science of acoustics took form in the seventeenth century. The fact that sound could not be seen was described as a significant hindrance to its understanding. But it was precisely during this time that a wide variety of sounds attracted broad scientific attention across Europe. Scholars, natural philosophers, and mathematicians investigated and experimented with (...) sound and musical instruments and developed theories of hearing. This article looks at the role of images, diagrams, and visualization techniques in late seventeenth-century acoustics, bringing together the history of sound and the history of scientific images. Focusing on water and light as the dominant analogies for sound, the article demonstrates that visualization was an important tool for thinking about sound and allowed for the circulation of theories and experiments. At the same time, the epistemic status of these images remained contested, as there was no single model that could explain the different ways sound behaves as it moves through space and that could be visualized.

This paper investigates a famous argument, first introduced by Richard Taylor, that attempts to establish a radical similarity in the concepts of space and time. The argument contends that the spatial and temporal aspects of material bodies are much more alike, or analogous, than has been hitherto acknowledged. As will be demonstrated, most of the previous investigations of Taylor and company have failed to pinpoint the weakest link in their complex of analogies. By concentrating on their most fundamental cases, (...) however, a substantial difference, or disanalogy, can be brought to light that undermines this purported equivalence of space and time.

Who can penetrate space or encounter the stream of time? Only those who are not fooled into believing that freedom from sensory conditions is attainable by moving beyond a space and a time considered real because of their measurability. The reality of time and space is immeasurable. It cannot be attained by overcoming the given forms of measurement, but rather by overcoming measurement itself. Before this can occur, we must know how and why measurement arises; we must (...) know what the spirit wants by containing within measurement the substance of its eternal telling of tales, whose truth alone justifies measurement--the transitory vision of what space and time are in their most subtle forms. This masterly book by Massimo Scaligero--author of The Light (La Luce): An Introduction to Creative Imagination--teaches us how to enter and recognize the spiritual reality behind and within what we objectify as space and time. Those who read The Secrets of Space and Time with meditative effort will be well rewarded with profound insights about the true nature of the world around us. The book is a translation from Italian of Segreti dello spazio e del tempo (Libreria Tilopa, Rome, 1963). (shrink)

An investigation of the views on space and time of the Russian polymath Pavel Florensky. After a brief account of his life, I study Florensky’s conception of time in The Meaning of Idealism, where he first confronts Einstein’s theory of special relativity, comparing it to Plato’s metaphor of the Cave and Goethe’s myth of the Mothers. Later, in his Analysis of spatiality and time, Florensky speaks of a person’s biography as a four-dimensional unity, in which the temporal coordinate is (...) examined in sections. In On the Imaginaries in Geometry, Florensky argues that the speed of light is not, as in Relativity, an absolute speed limit in the universe. When bodies approach and then surpass the speed of light, they are transformed into unextended, eternal Platonic forms. Beyond this point, time runs in reverse, effects precede their causes, and efficient causality is transformed into final or teleological causality, a concept on which Florensky elaborates in his Iconostasis. Florensky thus transformed the findings of Einsteinian relativity in order to make room for Plato’s intelligible Ideas, the Aristotelian distinction between a changing realm of earth and the immutable realm of the heavens, and the notion of teleology or final causation. His notion that man can approximate God’s vision of past, present and future all at once, as if from above, is reminiscent of Boethius’ ideas. (shrink)

This collection of original research explores ways that educators can create participatory spaces that foster civic engagement, critical thinking, and authentic literacy practices for adolescent youth in urban contexts. Casting youth as vital social actors, contributors shed light on the ways in which urban youth develop a clearer sense of agency within the structural forces of racial segregation and economic development that would otherwise marginalize and silence their voices and begin to see familiar spaces with reimagined possibilities for socially (...) just educational practices.

We consider a sequence of absolute-space kinematical theories which differ more or less from the special theory of relativity (STR) in the amount of clock retardation which they predict, but which agree with STR with respect to roundtrip light experiments, such as Michelson-Morley and Kennedy-Thorndike. This sequence of theories is imbedded in the synchrony-free formulation of STR developed by Winnie by modifying the equal passage time principle. The paper has bearing on the relationship between the slow clock transport (...) behavior of clocks and the one-way velocity of light. Experiments which claim to measure the latter are discussed.

The North American environmental movement has historically sought to redress the depletion and degradation of natural resources that has been the legacy of the industrial revolution. Predominant in this approach has been the preservation of wilderness, conservation of species biodiversity and the restoration of natural ecosystems. While the results of such activity have often been commendable, several scholars have pointed out that the environmental movement has inherited an unfortunate bias against urban environments, and consequently, a blind spot to ways in (...) which densely populated built spaces can serve to enhance rather than degrade efforts to achieve sustainability. After exploring this concern we argue that environmental architecture can serve as a counter-balance to this bias, focused, as it is, on the ways in which the construction and organisation of built spaces for humans can help or hinder the pursuit of environmental priorities. But if environmental architecture is to take this role then it must be understood in a broader context, one which does not exclude other moral, political and aesthetic values in the production of human environments. We will highlight several examples of how environmental architecture has combined success and failure at taking a broader view of environmental questions, with a specific focus on one green skyscraper that may be good for the natural environment but not necessarily for the human environment of the city.

In this essay, I explore a metaphor in geometry for the debate between the unity and the disunity of science, namely, the possibility of putting a global coordinate system (or a chart) on a manifold. I explain why the former is a good metaphor that shows what it means (and takes in principle) for science to be unified. I then go through some of the existing literature on the unity/disunity debate and show how the metaphor sheds light on some (...) of the views and arguments. (shrink)

There are many ways to describe cities. As a physical environment, more so than many other environments, they are at least an extension of our present intentions. But cities are not confined to the moment. Built spaces are also in conversation with the past and oriented toward the future as physical manifestations of our values and priorities. But even with all of the ways we have to describe cities we do not normally think of them as in any way akin (...) to the “natural” environment. City and country, nature and culture, are opposed. We move through cities differently, with a different set of values, whether articulated or not. Consider just one small example: Even the most jaded urban dweller may hesitate to sully the environment around him when he perceives it to be something other than a product of the human community. Though we have all seen trash in a national park, we suspect (or at least hope) that there is a kind of hesitancy that occurs with a person wondering what to do with her candy wrappers on a trail in Yosemite. On the other hand, a visitor to my home, Greenwich Village, will usually not think twice about tossing his cigarette butts on the ground as he walks toward his next destination. (shrink)

The longing for aerial flight has been one of mankind's most consuming preoccupations. A burning desire for lightness, verticality, and flight is opposed to the fatality of universal gravity. Jules Michelet, in his study of the subject, entitled L'Oiseau (The Bird), which he wrote toward the end of his life, deems this aspiration for upward motion to be characteristic of all nature. He writes: “It is the cry of all the earth, of the world and of all life… : ‘Wings! (...) We want wings, we want flight and movement.’” From ancient times, this basic element of physical experience has nourished human imagination and been a source of motivation for the pursuit of scientific knowledge. Mesopotamian civilization had its winged divinities and spirits; indeed the Western tradition of depicting winged persons has been linked to the influence of Mesopotamian art. As Jules Duhem has pointed out, four centuries before Jesus Christ, Aristotle himself was already exploring certain notions that have become part of the history of ideas of aeronautics and astronomy. Among these are the ideas of void, weight, the resistance of air, and the movement of birds and other flying creatures. Duhem has also demonstrated that Aristotle proposed an explanation, as imperfect as it was, for what causes projectiles to fall from the sky. Throughout the ages, humanity has continually expressed its desire to fly: “Man is proud of being free and of leaning on nothing,” Elias Canetti has written in regard to man's upright position. Striking examples of the impulse to fly are to be found not only in scientific discourse but in myths, literature, and works of art. (shrink)

AbstractThe sculptor Olafur Eliasson produces works together with his team that have two main goals: first, he intends to sensitize our daily perception of the world and our surroundings, and second, Eliasson’s works are not only works of art, but they also explore nature, the physical properties of light, of energy, of water, and other elements. With the famous project Little Suns, small plastic lamps with LED light bulbs and solar cells, he contributes to the amelioration of daily (...) life for those who do not have access to electricity even today. In other works he focuses on elementary phenomena such as the movement of elements in a vortex of water or air, on the properties of light, of mirrored light, or the fascinating world of kaleidoscopes. Some of these works are very popular and often include visitors such as the Weather Project in the Turbine Hall of the Tate Modern in London created in 2003. This work is said to have provoked spontaneous meetings, celebrations, and even episodes of civil protest. The work turned the museum into a kind of agora, the public square in Ancient Greek cities that was at the heart of daily life, of politics, of democratic practices. (shrink)

Science is critical and thrives on discourse. However, new challenges for science and academic freedom have arisen from an often-discussed cancel culture and an increasing demand for safe spaces, which are justified by their assumed protection against microaggressions. These phenomena can impede scientific progress and innovation by prohibiting certain thought processes and heterodox ideas that eventually result in new ideas, publications, statements, etc. In this paper, we use the approach of property rights ethics to shed light on these phenomena, (...) especially in academia. First, we argue that microaggressions must be generally tolerated according to property rights ethics as the starting point for discussion. Then, we analyze cancel culture and safe spaces in academia. To this end, we distinguish between two basic cases in the educational system. We show that cancel culture and safe spaces seem justifiable in a private education system but have no place in public, tax-funded universities from the perspective of property ethics. Our essay contributes, on the one hand, to the economic analysis of science and, on the other hand, to the ethical study of new phenomena in modern societies. (shrink)

Newton's Principia begins with eight formal definitions and a scholium, the so-called scholium on space and time. Despite a history of misinterpretation, scholars now largely agree that the purpose of the scholium is to establish and defend the de fi nitions of key concepts. There is no consensus, however, on how those definitions differ in kind from the Principia's formal definitions and why they are set-off in a scholium. The purpose of the present essay is to shed light (...) on the scholium by focusing on Newton's notion and use of de fi nition. The resulting view is developmental. I argue that when Newton first wrote the Principia, he viewed the scholium's definitions as items of “natural philosophy.” By the time of the third edition, however, he came to view their methodological status differently; he viewed them as belonging to the more qualified “manner of geometers.” I explicate the two methods of natural inquiry and draw out their implications for Newton's account of space.

A theoretical device, which incorporates the functions of clock, rod, nonrotating platform, and accelerometer, and whose operation depends on the properties of light rays and free particles, is defined. The device, which we call a metrosphere, is simple enough that it can be introduced at the starting point of relativity theory and versatile enough that it can serve as an aid in the development and conceptualization of the theory. Relative to an inertial frame, a moving metrosphere undergoes a Lorentz-Fitzgerald (...) contraction and the associated clock exhibits a Lorentz-Larmor rate retardation. From this fact and the assumption that there exists one inertial frame, it is possible to generate the kinematical results of special relativity. A metrosphere provides an observer with a local frame of reference, hence it is well adapted to the needs of general relativity, allows the equivalence principle to be introduced in a straightforward manner, and permits a smooth transition from special relativity to general relativity.

General Relativity’s Schwarzschild solution describes a spherically symmetric gravitational field as an utterly static thing. The Space Generation Model describes it as an absolutely moving thing. The light propagation time-delay experiment of Shapiro-Reasenberg [1] and the falling atomic clock experiment of Vessot-Levine [2] provide the ideal context for illustrating how, though the respective world views implied by these models are radically di fferent, they make nearly the same prediction for the results of these experiments.

This introduction to one of the liveliest and most popular fields in philosophy is written specifically for a beginning readership with no background in philosophy or science. Step-by-step analyses of the key arguments are provided and the philosophical heart of the issues is revealed without recourse to jargon, maths, or logical formulas. The book introduces Einstein's revolutionary ideas in a clear and simple way, along with the concepts and arguments of philosophers, both ancient and modern that have proved of lasting (...) value. Specifically, the theories of the ancient Greek philosophers, Zeno, Euclid and Parmenides are considered alongside the ideas of Newton, Leibniz and Kant as well as the giants of twentieth-century physics, Einstein and Lorentz. The problems at the heart of the philosophy of space and time, such as change, motion, infinity, shape, and inflation, are examined and the seismic impact made by relativity theory and quantum theory is assessed in the light of the latest research. The writing is lucid and entertaining, allowing a beginning readership to grasp some difficult concepts while offering the more experienced reader a succinct and illuminating presentation of the state of the debate. "Space, Time and Einstein" shows the reader the excitement of scientific discovery and the beauty of theory in the search for answers to these fundamental questions. (shrink)

An appropriate kind of curved Hilbert space is developed in such a manner that it admits operators of $\mathcal{C}$ - and $\mathfrak{D}$ -differentiation, which are the analogues of the familiar covariant and D-differentiation available in a manifold. These tools are then employed to shed light on the space-time structure of Quantum Mechanics, from the points of view of the Feynman ‘path integral’ and of canonical quantisation. (The latter contains, as a special case, quantisation in arbitrary curvilinear coordinates (...) when space is flat.) The influence of curvature is emphasised throughout, with an illustration provided by the Aharonov-Bohm effect. (shrink)

This study considers the contribution of Francesco Patrizi da Cherso to the development of the concepts of void space and an infinite universe. Patrizi plays a greater role in the development of these concepts than any other single figure in the sixteenth century, and yet his work has been almost totally overlooked. I have outlined his views on space in terms of two major aspects of his philosophical attitude: on the one hand, he was a devoted Platonist and (...) sought always to establish Platonism, albeit his own version of it, as the only currect philosophy; and on the other hand, he was more determinedly anti-Aristotelian than any other philosopher at that time. Patrizi's concept of space has its beginnings in Platonic notions, but is extended and refined in the light of a vigorous critique of Aristotle's position. Finally, I consider the influence of Patrizi's ideas in the seventeenth century, when various thinkers are seeking to overthrow the Aristotelian concept of place and the equivalence of dimensionality with corporeality. Pierre Gassendi , for example, needed a coherent concept of void space in which his atoms could move, while Henry More sought to demonstrate the reality of incorporeal entities by reference to an incorporeal space. Both men could find the arguments they needed in Patrizi's comprehensive treatment of the subject. (shrink)
