By focusing on the conceptual issues faced by nineteenth century physicists, this book clarifies the status of field theory, the ether, and thermodynamics in the work of the period. A remarkably synthetic account of a difficult and fragmentary period in scientific development.

This history of physics focuses on the question, "How do bodies act on one another across space?" The variety of answers illustrates the function of fundamental analogies or models in physics as well as the role of so-called unobservable entities. Forces and Fields presents an in-depth look at the science of ancient Greece, and it examines the influence of antique philosophy on seventeenth-century thought. Additional topics embrace many elements of modern physics--the empirical basis of quantum mechanics, wave-particle duality and the (...) uncertainty principle, and the action-at-a-distance theory of Wheeler and Feynman. 1961 ed.

The nature of life consists in a constructive becoming (see Analecta Husserliana vol. 70). Though caught up in its relatively stable, stationary intervals manifesting the steps of its accomplishments that our attention is fixed. In this selection of studies we proceed, in contrast, to envisage life in the Aristotelian perspective in which energia, forces, and dynamisms of life at work are at the fore. Startling questions emerge: `what distinction could be drawn between the prompting forces of life and its formation? (...) Or, is this distinction a result of our transcendental faculties?' The answers to these questions reveal themselves, as Tymieniecka proposes, at the phenomenologically ontopoietic level of life's origination where transcendentality surges. (shrink)

We address a long-standing debate over whether classical magnetic forces can do work, ultimately answering the question in the affirmative. In detail, we couple a classical particle with intrinsic spin and elementary dipole moments to the electromagnetic field, derive the appropriate generalization of the Lorentz force law, show that the particle's dipole moments must be collinear with its spin axis, and argue that the magnetic field does mechanical work on the particle's elementary magnetic dipole moment. As consistency checks, we (...) calculate the overall system's energy-momentum and angular momentum, and show that their local conservation equations lead to the same force law and therefore the same conclusions about magnetic forces and work. We also compute the system's Belinfante-Rosenfeld energy-momentum tensor. (shrink)

Systemic Constellation Work is a rapidly growing experiential healing process that is being embraced by a variety of helping professionals, both traditional and alternative, worldwide. This book explores the history, principles and methodology of this approach, and offers a detailed comparison with psychodrama - the original mind-body therapy - explaining how each method can enhance the other. Constellation work is based on the notion that people are connected by unseen energetic forces and suggests that the psychological, traumatic and survival experiences (...) of our ancestors are genetically passed forward to the next generation and may live within us. Using insightful case studies from a variety of client groups, this book shows how Systemic Constellation Work can expand the possibilities of psychodrama techniques, and can be successfully integrated with psychodramatic enactment, guided imagery, ritual, concretization and other methods of healing and personal growth. This book will be essential reading for students and practitioners of psychodrama and Constellation work, as well as counselors, mental health professionals, experiential therapists, creative and expressive arts therapists and alternative practitioners looking to widen their knowledge of mind-body therapies.

In lieu of an abstract, here is a brief excerpt of the content:Force and Translation; Or, The Polymorphous Body of LanguageElissa MarderOr un corps verbal ne se laisse pas traduire ou transporter dans une autre langue. Il est cela même que la traduction laisse tomber. Laisser tomber le corps, telle est même l’énergie essentielle de la traduction. Quand elle réinstitue un corps, elle est poésie.—Jacques Derrida, “Freud et la scène de l’écriture”The materiality of a word cannot be translated or (...) carried over into another language. Materiality is precisely that which translation relinquishes. To relinquish materiality: such is the driving force of translation. And when that materiality is reinstated, translation becomes poetry.—Jacques Derrida, “Freud and the Scene of Writing”Babel Revisited (The Mother Tongue and The Translation Machine)On January 20, 2012, Lawrence Summers, former president of Harvard and former Secretary of the U.S. Treasury, boldly announced a six-point vision for reforming the U.S. education system in a New York Times Education supplement editorial modestly entitled, “What you (Really) Need to Know.” For the [End Page 1] purposes of this discussion, I will limit myself here to a brief examination of what he says about the study of foreign languages and the merits of machine translation in the item listed as “number 5”:5. The world is much more open, and events abroad affect the lives of Americans more than ever before. This makes it essential that the educational experience breed cosmopolitanism—that students have international experiences, and classes in the social sciences draw on examples from around the world. It seems logical, too, that more in the way of language study be expected of students. I am not so sure.English’s emergence as the global language, along with the rapid progress in machine translation and the fragmentation of languages spoken around the world, make it less clear that the substantial investment necessary to speak a foreign tongue is universally worthwhile. While there is no gainsaying the insights that come from mastering a language, it will over time become less essential in doing business in Asia, treating patients in Africa or helping resolve conflicts in the Middle East.For those of us who still earn our living by teaching literary texts written in foreign languages in foreign language departments in the university, Summers’s breezy assessment that the university of the future need not (indeed ought not) include extensive foreign language study is, sadly, not exactly news. On the contrary, there is nothing particularly innovative or original about the position he advocates here: his vision of a future “global” American university—in which virtually all speculative activities are conducted solely in English—has already begun to be implemented in various colleges and universities around the world. If his remarks are nonetheless noteworthy, it is because of his apparent willingness—even eagerness—to defend a policy that university officials often officially still pretend to abhor. Indeed, Summers’s position goes far beyond the more familiar pragmatic voices that have concluded that the reduction of foreign language instruction is a necessary and unavoidable consequence of the unfortunate economic reality that the American university as we once knew it has become financially untenable and hence unable to accommodate areas of study that can be construed as nonessential. Instead, Summers goes a step farther: he actively advocates against investing precious university resources in foreign language study on ideological, political, quasi-philosophical, or dare I say it, perhaps even theological, grounds. By appealing to the value of what he calls here “cosmopolitanism,” he clearly implies that English’s status as “global language” discharges English speakers in the U.S. university system from any potential obligation to any other language on the globe. [End Page 2]According to Summers, English is optimally positioned to be a vehicle for genuine “cosmopolitanism” because, as a so-called “global language,” it constitutes a receptive, inclusive, and welcoming “common ground” for multicultural exchange that would be otherwise impossible given the sheer volume and overwhelming diversity of all the other languages in the world. In other words, in his opinion, recourse to English actually facilitates and enhances—rather than inhibits—genuine multicultural encounters as it offsets the potentially... (shrink)

This book presents a new approach to studying the syntax of human language, one which emphasizes how we think about time. Tilsen argues that many current theories are unsatisfactory because those theories conceptualize syntactic patterns with spatially arranged structures of objects. These object-structures are atemporal and do not lend well to reasoning about time. The book develops an alternative conceptual model in which oscillatory systems of various types interact with each other through coupling forces, and in which the relative energies (...) of those systems are organized in particular ways. Tilsen emphasizes that the two primary mechanisms of the approach - oscillators and energy levels - require alternative ways of thinking about time. Furthermore, his theory leads to a new way of thinking about grammaticality and the recursive nature of language. The theory is applied to a variety of syntactic phenomena: word order, phrase structure, morphosyntax, constituency, case systems, ellipsis, anaphora, and islands. The book also presents a general program for the study of language in which the construction of linguistic theories is itself an object of theoretical analysis. (shrink)

Einstein claimed that the fundamental dynamical insight of special relativity was the equivalence of mass and energy. I disagree. Not only are mass and energy not equivalent but talk of such equivalence obscures the real dynamical insight of special relativity, which concerns the nature of 4-forces and interactions more generally. In this paper I present and defend a new ontology of special relativistic particle dynamics that makes this insight perspicuous and I explain how alleged cases of mass–energy (...) conversion can be accommodated within that ontology.

This volume collects academic as well as artistic explorations highlighting historical and contemporary approaches to the energetic in its aesthetic and political potential. Energetic processes straddle dance, performance art, and installations. They transform the body, evoke specific states, and push towards intensities. In contemporary dance and performance art, energetic processes are no longer mere conditions of form but appear as distinct aesthetic interventions. The contributions in this volume submit these to thorough investigation, elucidating maneuvers of mobilization, activation, initiation, regulation, navigation, (...) and containment of forces as well as different potentials and associated with the energetic.

Instead of relying on the usual price elasticity technique, this book combines economic and engineering analysis to study economic growth and energy demands to the year 2000. It asserts that future energy demand will be determined by two basic factors--the gross national product and the efficiency with which energy is used to produce this output in the household, commercial, industrial, and transport sectors of the economy.Labor hours multiplied by a productivity factor results in the GNP. This study (...) predicts that, in the long run, productivity in the United States will recover most of the sharp losses registered in the past five years. The study points out the decelerating population growth, the higher number of women in the labor force, and new investments as having an influence on this situation.After projecting the size and composition of each of the four energy consuming sectors that account for the total GNP. Energy and Economic Growth estimates efficiency improvements for each. It shows, for example, that higher levels of thermal insulation will reduce sharply energy needs for household heating and cooling. Similarly, the study notes that improvements in energy consumption per dollar of output can be made for each of the energy intensive manufacturing industries, nothing that although the savings in energy are significant, none is a consequence of pushing improvements to known technological limits. Finally, the book establishes the price elasticities that are inherent in the calculated energy requirements and checks these against elasticity estimates made by other researchers. (shrink)

This book provides the reader with a detailed and captivating account of the story where, for the first time, physicists ventured into proposing a new force of nature beyond the four known ones - the electromagnetic, weak and strong forces, and gravitation - based entirely on the reanalysis of existing experimental data. Back in 1986, Ephraim Fischbach, Sam Aronson, Carrick Talmadge and their collaborators proposed a modification of Newton's Law of universal gravitation. Underlying this proposal were three tantalizing pieces (...) of evidence: 1) an energy dependence of the CP (particle-antiparticle and reflection symmetry) parameters, 2) differences between the measurements of G, the universal gravitational constant, in laboratories and in mineshafts, and 3) a reanalysis of the Eötvos experiment, which had previously been used to show that the gravitational mass of an object and its inertia mass were equal to approximately one part in a billion. The reanalysis revealed that, contrary to Galileo's position, the force of gravity was in fact very slightly different for different substances. The resulting Fifth Force hypothesis included this composition dependence and also added a small distance dependence to the inverse-square gravitational force. Over the next four years numerous experiments were performed to test the hypothesis. By 1990 there was overwhelming evidence that the Fifth Force, as initially proposed, did not exist. This book discusses how the Fifth Force hypothesis came to be proposed and how it went on to become a showcase of discovery, pursuit and justification in modern physics, prior to its demise. In this new and significantly expanded edition, the material from the first edition is complemented by two essays, one containing Fischbach's personal reminiscences of the proposal, and a second on the ongoing history and impact of the Fifth Force hypothesis from 1990 to the present. <.

Investigating the concepts and material realities of energy coursing through the arts: a foundational text. This book investigates energies—in the plural, the energies embedded and embodied in everything under the sun— as they are expressed in the arts. With contributions from scholars and critics from the visual arts, art history, anthropology, music, literature, and the history of science, it offers the first multidisciplinary investigation of the concepts and material realities of energy coursing through the arts. Just as Douglas (...) Kahn's earlier books helped introduce sound as a category for study in the arts, this new volume will be a foundational volume for future explorers in a largely uncharted domain. The modern concept of energy is only two hundred years old—an abstraction grounded in extraction—but this book takes a more expansive view. It opens with a clap: the sonic energies in a ceremony of the indigenous Goolarabooloo people of Australia. Other chapters explore the energies of photography; responses of artists in the early twentieth century—including Marcel Duchamp—to scientific discoveries in electricity and electromagnetism; the aestheticization of entropy in works by Hans Haacke and Robert Smithson; free-jazz musician Milford Graves's cross-cultural engagement with music, science, and spiritualism; energy field performance; and the self-generating energy of rumor and gossip as artwork. Contributors include such leading scholars as Linda Dalrymple Henderson, John Tresch, and Caroline A. Jones. Practicing artists and students of art history will find Energies in the Arts an essential work. Contributors Susan Ballard, Jennifer Biddle, Marcus Boon, Joan Brassil, Steven Connor, Milford Graves, Daniel Hackbarth, Linda Dalrymple Henderson, Caroline A.

Fire is a force that links everyday human activities to some of the most powerful energetic movements of the Earth. Drawing together the energy-centred social theory of Georges Bataille, the fire-centred environmental history of Stephen Pyne, and the work of a number of ‘pyrotechnology’ scholars, the paper proposes that the generalized study of combustion is a key to contextualizing human energetic practices within a broader ‘economy’ of terrestrial and cosmic energy flows. We examine the relatively recent turn (...) towards fossil-fuelled ‘internal combustion’ in the light of a much longer human history of ‘broadcast’ burning of vegetation and of artisanal pyrotechnologies – the use of heat to transform diverse materials. A combustion-centred analysis, it is argued, brings human collective life into closer contact with the geochemical and geologic conditions of earthly existence, while also pointing to the significance of explorative, experimental and even playful dispositions towards energy and matter.

According to the BSM- Supergravitation Unified Theory (BSM-SG), the energy is indispensable feature of matter, while the matter possesses hierarchical levels of organization from a simple to complex forms, with appearance of fields at some levels. Therefore, the energy also follows these levels. At the fundamental level, where the primary energy source exists, the matter is in its primordial form, where two super-dense fundamental particles (FP) exist in a classical pure empty space (not a physical vacuum). They (...) are associated with the Planck scale parameters of frequency and distance and interact by Supergravitational forces. These forces are inverse proportional to the cube of distance at pure empty space and they are based on frequency interactions. Since the two FPs have different intrinsic frequencies, the SG forces appear different for interactions between the like and unlike FPs and may change the sign. This primordial form of matter exists in the super-heavy black holes located in the center of each well formed galaxy. The next upper level of matter organization includes the underlying structure of the physical vacuum, called a Cosmic Lattice, and the structure of elementary particles. They have common substructure elements obtained by specific crystallization process preceding the formation of the observable galaxies. The Cosmic Lattice, forming a space known as a physical vacuum, is responsible for the existence and propagation of the physical fields: electrical, magnetic, Newtonian gravity and inertia. The energy of physical vacuum is in two forms: Static (enormous) and Dynamic (weak). The Static energy is directly related to the Newtonian mass by the Einstein equation E = mc^2 and it is a primary source of the nuclear energy. The Dynamic energy is responsible for the existence of the electric and magnetic fields, the constant speed of light and the quantum mechanical properties of the physical vacuum. The next upper energy level is the dynamical energy of excited atoms and molecules. At this level a hidden energy wells exit, such as the internal energy of the electron and the internal energy of atoms with more than one electron. The next upper energy level is at some organic molecules and particularly in the biomolecules that contain ring atomic structures. In such a structure, some quantum states are not emitted immediately, but rotating in the ring. While in organic molecules the energy stored in such a ring is released by a chemical process, in the long chain molecule of proteins in the living organism the stored energy can be released simultaneously by triggering. A huge number of atomic rings are contained in the DNA strands. The release of the energy stored in DNA, for example, is an avalanche process that causes an emission of entangled photons possessing a strong penetrating capability. A sequence of entangled photons emitted by DNA should carry the genetic information encoded by the cordons. This mechanism, predicted in BSM-SG theory, is very important for intercommunication between the cells of the living organism. The next upper level of energy organization may exist in the brain. The brain is an organ of a most abundant number of atomic rings, while its tissue environment might permit complex energy interactions. The human brain contains billions of atomic rings. The next hypothetical upper level of energy organization is an information field, physically existed outside, but connected with the living brain. It corresponds to a specific field known as aura, while the possibility of its existence is still not accepted by the main stream science. The problem is that this field could not be detected by the currently existing technical means used for EM communications. The BSM-SG predicts that this field might differ from the EM field we use for communication, but it is a subject of a further theoretical development that must be supported by experiments using specifically designed technical means. According to the BSM-SG theory, the energy conversion from the primary energy source to the complex levels of matter and field organization is a permanent syntropic process based on complex resonance interactions.

SummaryFaraday's concept of force is described by six assumptions. These specify a concept that is quite distinct from ‘mechanical’ conceptions of his contemporaries and interpreters. Analysis of the role of these assumptions clarifies Faraday's weighting of experimental evidence and shows how closely-linked Faraday's chemistry and physics were to his theology. It is argued that Faraday was unable to secularize his concept of force by breaking the ties between his physics and his theology of nature. Examination of his basic (...) assumptions also explains Faraday's failure to quantify his principle of conservation of force, his rejection of mechanical concepts of force and energy, and his early attempt to develop a wave-model for the conversion and transmission of electricity, magnetism, light and heat.

In order to assess the tenacity of psychoanalysts in continuing to use a concept of psychic energy, it is advisable to consider whether, as they sometimes claim, the concepts of energy, force, and work in psychoanalysis are akin to those in the natural sciences. Strong disanalogies suggest that the psychoanalytic concepts are quite different and used equivocally even within psychoanalysis. However, they may not be subject to the objections which certain critical psychoanalysts have raised.

Misconceptions about energy conservation abound due to the gap between physics and secondary school chemistry. This paper surveys this difference and its relevance to the 1690s–2010s Leibnizian argument that mind-body interaction is impossible due to conservation laws. Justifications for energy conservation are partly empirical, such as Joule’s paddle wheel experiment, and partly theoretical, such as Lagrange’s statement in 1811 that energy is conserved if the potential energy does not depend on time. In 1918 Noether generalized results (...) like Lagrange’s and proved a converse: symmetries imply conservation laws and vice versa. Conservation holds if and only if nature is uniform. The rise of field physics during the 1860s–1920s implied that energy is located in particular places and conservation is primordially local: energy cannot disappear in Cambridge and reappear in Lincoln instantaneously or later; neither can it simply disappear in Cambridge or simply appear in Lincoln. A global conservation law can be inferred in some circumstances. Einstein’s General Relativity, which stimulated Noether’s work, is another source of difficulty for conservation laws. As is too rarely realized, the theory admits conserved quantities due to symmetries of the Lagrangian, like other theories. Indeed General Relativity has more symmetries and hence more conserved energies. An argument akin to Leibniz’s finally gets some force. While the mathematics is too advanced for secondary school, the ideas that conservation is tied to uniformities of nature and that energy is in particular places, are accessible. Improved science teaching would serve the truth and enhance the social credibility of science. (shrink)

One of the major reasons underlying the widespread rejection of the theory that the mind is an immaterial substance distinct from the body, But which nevertheless acts on the body, Is that it is felt that such a theory commits one to denying the principle of the conservation of energy.

My thesis is that the usual replies are inadequate, But--Strong as this objection appears--Some important logical distinctions (...) have been overlooked and when these are taken into account its force vanishes.

As the last of the Jedi, Luke must now pass on what he has learned of the Force, presumably to restart the Jedi Order. In the imaginations of many, Luke simply must have continued his rise, becoming one of the most powerful living beings in the universe. Deleuze draws his notion of the forces of becoming partly from German philosopher Friedrich Nietzsche, who says that the world is “a monster of energy, without beginning, without end” that “only transforms (...) itself” as “a play of forces and waves of forces, a sea of forces flowing and rushing together, eternally changing, with an ebb and a flood of its forms.” Deleuze's interpretation is that all bodies, all physical things, are “nothing but forces” defined solely by their activities of affecting – and being affected by – other things with which they interact.

The aim of this paper is to familiarize the reader with the concept of psychological energy, and the role it plays in deepening our understanding of psychosocial adaptation to traumatic life events and, more pointedly, the onset of chronic illness and disability. In order to implement this aim, the following steps were undertaken: First, a brief historical review of the nature of energy, force and action, as traditionally conceived in the field of physics, is provided. Second, an (...) overview of PE is presented, with a shared emphasis on both its historical underpinnings and its present conceptualizations in the fields of social, health and rehabilitation psychology. Particular emphasis is placed upon applications of PE in the domains of adaptation to stress, trauma and CID onset. Third, reviewed are measuring instruments that have been traditionally applied to the assessment of the nature, content and magnitude of PE and its dynamics. Finally, new perspectives are offered on the dimensional structure, processes and dynamics, assumed to undergird PE, its underlying conceptual similarities to physical energy, and its potential and deeper link to the process of psychosocial adaptation in the aftermath of experiencing trauma and CID.

Science once had an unshakable faith in its ability to bring the forces of nature—even human nature—under control. In this wide-ranging book Anson Rabinbach examines how developments in physics, biology, medicine, psychology, politics, and art employed the metaphor of the working body as a human motor. From nineteenth-century theories of thermodynamics and political economy to the twentieth-century ideals of Taylorism and Fordism, Rabinbach demonstrates how the utopian obsession with energy and fatigue shaped social thought across the ideological spectrum.

Children’s exposure to the marketing of energy-dense nutrient-poor (EDNP) foods is a public health concern and marketing investment is known to be shifting to non-broadcast media, such as the Internet. This paper examines the perceptions of parents and children on ethical aspects of food marketing to which children are exposed. The research used qualitative methods with parent-child (aged between 8–13 years), from South Australia. Thirteen parent-child pairs participated in this research. Ethical concerns raised by parents and children included, the (...) marketing of EDNP foods, pester power and family conflict and the use of powerful techniques via the Internet. Their views on rights and responsibilities represented a complex mixture of idealistic and pragmatic positions. They appeared to be caught within the tensions of problematizing unhealthy food marketing to children, both as a social problem and as an individual problem. Their dilemmas are not dissimilar to the broader policy debate in Australia on the matter of food marketing to children. The stale-mate on statutory regulations to protect children from exposure to EDNP food marketing could be advanced by stronger use of ethical arguments to protect children from harmful exploitation and to protect parents from forces that undermine their authority.

The paper investigates the status of gravitational energy in Newtonian Gravity, developing upon recent work by Dewar and Weatherall. The latter suggest that gravitational energy is a gauge quantity. This is potentially misleading: its gauge status crucially depends on the spacetime setting one adopts. In line with Møller-Nielsen’s plea for a motivational approach to symmetries, we supplement Dewar and Weatherall’s work by discussing gravitational energy–stress in Newtonian spacetime, Galilean spacetime, Maxwell-Huygens spacetime, and Newton–Cartan Theory. Although we ultimately (...) concur with Dewar and Weatherall that the notion of gravitational energy is problematic in NCT, our analysis goes beyond their work. The absence of an explicit definition of gravitational energy–stress in NCT somewhat detracts from the force of Dewar and Weatherall’s argument. We fill this gap by examining the supposed gauge status of prima facie plausible candidates—NCT analogues of gravitational energy–stress pseudotensors, the Komar mass, and the Bel-Robinson tensor. Our paper further strengthens Dewar and Weatherall’s results. In addition, it sheds more light upon the subtle link between sufficiently rich inertial structure and the definability of gravitational energy in NG. (shrink)

In this paper I present a novel supertask in a Newtonian universe that destroys and creates infinite masses and energies, showing thereby that we can have infinite indeterminism. Previous supertasks have managed only to destroy or create finite masses and energies, thereby giving cases of only finite indeterminism. In the Nothing from Infinity paradox we will see an infinitude of finite masses and an infinitude of energy disappear entirely, and do so despite the conservation of energy in all (...) collisions. I then show how this leads to the Infinity from Nothing paradox, in which we have the spontaneous eruption of infinite mass and energy out of nothing. I conclude by showing how our supertask models at least something of an old conundrum, the question of what happens when the immovable object meets the irresistible force. (shrink)

Examining the process of action at a distance, we arrive at the following conclusions: (a) The virtual photons and mesons transmitting Coulomb and nuclear forces, respectively, do not arise from “temporary violations of energy conservation,” but, on the contrary, exactly embody the potential energy corresponding to the relevant forceF that they transmit on their collision with the charged particles or nucleons via the formula Δp=FΔt. (b) In the case of an attractive force, the energy of these (...) photons and mesons is negative. The way this comes about is made clear by a more detailed investigation of Feynman's notion of “traveling backward in time.” (c) The action corresponding to, e.g., a virtual photon's appearance is exactly one quantumh, which fact is responsible for the unobservability of such photons. Some consequences of the revised conception of potential energy for, e.g., the tunnel and the Bohm-Aharonov effect are mentioned. (shrink)

Throughout the history of mankind, energy security has been always seen as a means of protection from disruptions of essential energy systems. The idea of protection from disorders emerged from the process of securing political and military control over energy resources to set up policies and measures on managing risks that affect all elements of energy systems. The various systems placed in a place to achieve energy security are the driving force towards the (...) class='Hi'>energy innovations or emerging trends in the energy sector. Our paper discusses energy security status and innovations in the energy sector in European Union (EU). We analyze the recent up-to-date developments of the energy policy and exploitation of energy sources, as well as scrutinize the channels of energy streaming to the EU countries and the risks associated with this energy import. Moreover, we argue that the shift to the low-carbon production of energy and the massive deployment of renewable energy sources (RES) might become the key issue in ensuring the energy security and independency of the EU from its external energy supplies. Both RES, distributed energy resources (DER) and “green energy” that will be based on the energy efficiency and the shift to the alternative energy supply might change the energy security status quo for the EU.

Zeilinger's observation that phenomena of the Aharonov-Bohm type lead to non-dispersive, i.e., energy-independent, phase shifts in interferometers is generalized in a new proof which shows that the precise condition for nondispersivity is a force-free interaction. The converse theorem is disproved by a conceptual counter-example. Applications to several nondispersive interference phenomena are reviewed briefly. Those fall into two classes which are objectively distinct from each other in that in the first class phase shifts depend only on the topology of (...) the interfering beam paths, while in the second class force-free physical interactions take place at identifiable points along the path. Apparent disagreements in the literature about the topological nature of the phenomena in the second class stem from differing definitions. (shrink)
