  1. Beyond the orthodox QTAIM: motivations, current status, prospects and challenges. [REVIEW]Shant Shahbazian - 2012 - Foundations of Chemistry 15 (3):287-302.
    Recently, the author of this paper and his research team have extended the orthodox quantum theory of atoms in molecules (QTAIM) to a novel paradigm called the two-component QTAIM (TC-QTAIM). This extended framework enables one to incorporate nuclear dynamics into the AIM analysis as well as performing AIM analysis of the exotic species; positronic and muonic species are a few examples. In present paper, this framework has been reviewed, providing some computational examples with particular emphasis on origins and applications, in (...)

    Quasiclassical Born–Oppenheimer Approximations.Oleg Zaitsev, R. Narevich & R. E. Prange - 2001 - Foundations of Physics 31 (1):7-26.
    We discuss several problems in quasiclassical physics for which approximate solutions were recently obtained by a new method, and which can also be solved by novel versions of the Born–Oppenheimer approximation. These cases include the so-called bouncing ball modes, low angular momentum states in perturbed circular billiards, resonant states in perturbed rectangular billiards, and whispering gallery modes. Some rare, special eigenstates, concentrated close to the edge or along a diagonal of a nearly rectangular billiard are found. This kind of (...)

    Beyond the Born Rule in Quantum Gravity.Antony Valentini - 2022 - Foundations of Physics 53 (1):1-36.
    We have recently developed a new understanding of probability in quantum gravity. In this paper we provide an overview of this new approach and its implications. Adopting the de Broglie–Bohm pilot-wave formulation of quantum physics, we argue that there is no Born rule at the fundamental level of quantum gravity with a non-normalisable Wheeler–DeWitt wave functional \(\Psi\). Instead the universe is in a perpetual state of quantum nonequilibrium with a probability density \(P\ne \left| \Psi \right| ^{2}\). Dynamical relaxation to the (...)

    Born to Count.Jacob Beck & Sam Clarke - 2023 - Scientific American 328 (3):42-49.
    Imagine hosting a party. You arrange snacks, curate a playlist and place a variety of beers in the refrigerator. Your first guest shows up, adding a six-pack before taking one bottle for himself. You watch your next guest arrive and contribute a few more beers, minus one for herself. Ready for a drink, you open the fridge and are surprised to find only eight beers remaining. You haven't been consciously counting the beers, but you know there should be more, so (...)

    Ground State H-Atom in Born-Infeld Theory.S. Habib Mazharimousavi & M. Halilsoy - 2012 - Foundations of Physics 42 (4):524-530.
    Within the context of Born-Infeld (BI) nonlinear electrodynamics (NED) we revisit the non-relativistic, spinless H-atom. The pair potential computed from the Born-Infeld equations is approximated by the Morse type potential with remarkable fit over the critical region where the convergence of both the short and long distance expansions slows down dramatically. The Morse potential is employed to determine both the ground state energy of the electron and the BI parameter.

    Matters are not so clear on the physical side.Mario Castagnino - 2010 - Foundations of Chemistry 12 (2):159-166.
    According to ontological reductionism, molecular chemistry refers, at last, to the quantum ontology; therefore, the ontological commitments of chemistry turn out to be finally grounded on quantum mechanics. The main problem of this position is that nobody really knows what quantum ontology is. The purpose of this work is to argue that the confidence in the existence of the physical entities described by quantum mechanics does not take into account the interpretative problems of the theory: in the discussions about the (...)

    Kinematical and gravitational analysis of the rocket-borne clock experiment by Vessot and Levine using the revised Robertson's test theory of special relativity.José G. Vargas - 1986 - Foundations of Physics 16 (10):1003-1020.
    The kinematic aspects of the rocket-borne clock experiment by Vessot and Levine are analyzed with the revised Robertson's test theory of special relativity (Found. Phys. 14, 625 (1984)). Besides the expected time-dilation, it is found that the intermediate steps of this experiment yield in principle Michelson-Morley type information (a relation between longitudinal and transverse length contractions) in the third order of the velocities involved, but no relativity-of-simultaneity related effects.The flat space-time test theory induces a family of “spherically symmetric” line elements (...)

    Detection Model Based on Representation of Quantum Particles by Classical Random Fields: Born’s Rule and Beyond. [REVIEW]Andrei Khrennikov - 2009 - Foundations of Physics 39 (9):997-1022.
    Recently a new attempt to go beyond quantum mechanics (QM) was presented in the form of so called prequantum classical statistical field theory (PCSFT). Its main experimental prediction is violation of Born’s rule which provides only an approximative description of real probabilities. We expect that it will be possible to design numerous experiments demonstrating violation of Born’s rule. Moreover, recently the first experimental evidence of violation was found in the triple slit interference experiment, see Sinha, et al. (Foundations of Probability (...)

    The chemist’s concept of molecular structure.N. Sukumar - 2008 - Foundations of Chemistry 11 (1):7-20.
    The concept of molecular structure is fundamental to the practice and understanding of chemistry, but the meaning of this term has evolved and is still evolving. The Born–Oppenheimer separation of electronic and nuclear motions lies at the heart of most modern quantum chemical models of molecular structure. While this separation introduces a great computational and practical simplification, it is neither essential to the conceptual formulation of molecular structure nor universally valid. Going beyond the Born–Oppenheimer approximation introduces new paradigms, bringing (...)

    Mereology and quantum chemistry: the approximation of molecular orbital. [REVIEW]Jean-Pierre Llored - 2010 - Foundations of Chemistry 12 (3):203-221.
    Mulliken proposed an Aufbauprinzip for the molecules on the basis of molecular spectroscopy while establishing, point by point, his concept of molecular orbit. It is the concept of electronic state which becomes the lever for his attribution of electronic configurations to a molecule. In 1932, the concept of orbit was transmuted into that of the molecular orbital to integrate the probabilistic approach of Born and to achieve quantitative accuracy. On the basis of the quantum works of Hund, Wigner, Lennard-Jones and (...)

    In this article I examine several related views expressed by Robin Hendry concerning molecular structure, emergence and chemical bonding. There is a long-standing problem in the philosophy of chemistry arising from the fact that molecular structure cannot be strictly derived from quantum mechanics. Two or more compounds which share a molecular formula, but which differ with respect to their structures, have identical Hamiltonian operators within the quantum mechanical formalism. As a consequence, the properties of all such isomers yield precisely the (...)

    Do molecules have structure in isolation? How models can provide the answer.Vanessa Seifert - 2022 - In Olimpia Lombardi, Juan Camilo Martínez & Sebastian Fortin (eds.), Philosophical Perspectives on Quantum Chemistry. Springer Cham. pp. 125–143.
    I argue that molecules may not have structure in isolation. I support this by investigating how quantum models identify structure for isolated molecules. Specifically, I distinguish between two sets of models: those that identify structure in isolation and those that do not. The former identify structure because they presuppose structural information about the target system via the Born- Oppenheimer approximation. However, it is an idealisation to assume structure in isolation because there is no empirical evidence of this. In fact, (...)

    Sobre la ontología de la química cuántica.Juan Camilo Martínez González - 2019 - Tópicos: Revista de Filosofía 58:325-346.
    Quantum chemistry is the branch of chemistry whose primary focus is the application of quantum mechanics to chemical systems at the molecular level. Precisely due to its peculiar position between chemistry and physics, in the last times it has begun to engage the interest of the philosophers of chemistry. Nevertheless, in this philosophical field, quantum chemistry has been studied mainly from a historical viewpoint or from a perspective interested on methodological issues. By contrast, the question that will guide this article (...)

  17. No Time for Time from No-Time.Eugene Y. S. Chua & Craig Callender - 2021 - Philosophy of Science 88 (5):1172-1184.
    Programs in quantum gravity often claim that time emerges from fundamentally timeless physics. In the semiclassical time program time arises only after approximations are taken. Here we ask what justifies taking these approximations and show that time seems to sneak in when answering this question. This raises the worry that the approach is either unjustified or circular in deriving time from no–time.

    Hard lessons: learning from the Charlie Gard case.Dominic Wilkinson & Julian Savulescu - 2018 - Journal of Medical Ethics 44 (7):438-442.
    On 24 July 2017, the long-running, deeply tragic and emotionally fraught case of Charlie Gard reached its sad conclusion. Following further medical assessment of the infant, Charlie’s parents and doctors finally reached agreement that continuing medical treatment was not in Charlie’s best interests. Life support was subsequently withdrawn and Charlie died on 28 July 2017.Box 1 ### Case summary and timeline21–23 Charlie Gard was born at full term, apparently healthy, in August 2016.

    “It’s all about trust”: reflections of researchers on the complexity and controversy surrounding biobanking in South Africa.Keymanthri Moodley & Shenuka Singh - 2016 - BMC Medical Ethics 17 (1):57.
    Biobanks are precariously situated at the intersection of science, genetics, genomics, society, ethics, the law and politics. This multi-disciplinarity has given rise to a new discourse in health research involving diverse stakeholders. Each stakeholder is embedded in a unique context and articulates his/her biobanking activities differently. To researchers, biobanks carry enormous transformative potential in terms of advancing scientific discovery and knowledge. However, in the context of power asymmetries in Africa and a distrust in science born out of historical exploitation, researchers (...)

    Addressing or reinforcing injustice? Artificial amnion and placenta technology, loss-sensitive care and racial inequities in preterm birth.Sophie L. Schott, Faith Fletcher, Alice Story & April Adams - 2024 - Journal of Medical Ethics 50 (5):316-317.
    Preterm birth is defined as delivery occurring before 37 weeks gestation.1 Infants born prematurely have increased risks of morbidity and mortality throughout life, especially during the first year. These risks increase as the gestational age at birth decreases.2 Additionally, there are significant racial and ethnic differences in preterm birth rates. In 2022, the rate of preterm birth among non-Hispanic black women was approximately 50% higher than that observed in non-Hispanic white women.1 The outcomes for these infants are also disparate–preterm birth (...)

    On the Date of the Trial of Anaxagoras.A. E. Taylor - 1917 - Classical Quarterly 11 (02):81-.
    It is a point of some interest to the historian of the social and intellectual development of Athens to determine, if possible, the exact dates between which the philosopher Anaxagoras made that city his home. As everyone knows, the tradition of the third and later centuries was not uniform. The dates from which the Alexandrian chronologists had to arrive at their results may be conveniently summed up under three headings, date of Anaxagoras' arrival at Athens, date of his prosecution and (...)

    Medical assistance in dying was legalized in Canada in 2016. As of July 2017, approximately 2149 patients have accessed MAID. There remains no national-level data on the perspectives of future physicians about MAID or its changing legal status. We provide evidence from a national survey of Canadian medical students about their opinions, intentions, and concerns about MAID. From October 2016 to July 2017, we distributed an anonymous online survey to all students at 15 of Canada’s 17 medical schools. The survey (...)

    The beginning of the end for chimpanzee experiments?Andrew Knight - 2008 - Philosophy, Ethics, and Humanities in Medicine 3:16-.
    The advanced sensory, psychological and social abilities of chimpanzees confer upon them a profound ability to suffer when born into unnatural captive environments, or captured from the wild – as many older research chimpanzees once were – and when subsequently subjected to confinement, social disruption, and involuntary participation in potentially harmful biomedical research. Justifications for such research depend primarily on the important contributions advocates claim it has made toward medical advancements. However, a recent large-scale systematic review indicates that invasive chimpanzee (...)

    Generation Y’s Ethical Ideology and Its Potential Workplace Implications.Rebecca A. VanMeter, Douglas B. Grisaffe, Lawrence B. Chonko & James A. Roberts - 2013 - Journal of Business Ethics 117 (1):93-109.
    Generation Y is a cohort of the population larger than the baby boom generation. Consisting of approximately 80 million people born between 1981 and 2000, Generation Y is the most recent cohort to enter the workforce. Workplaces are being redefined and organizations are being pressed to adapt as this new wave of workers is infused into business environments.

    Pilot-Wave Quantum Theory with a Single Bohm’s Trajectory.Francesco Avanzini, Barbara Fresch & Giorgio J. Moro - 2016 - Foundations of Physics 46 (5):575-605.
    The representation of a quantum system as the spatial configuration of its constituents evolving in time as a trajectory under the action of the wave-function, is the main objective of the de Broglie–Bohm theory. However, its standard formulation is referred to the statistical ensemble of its possible trajectories. The statistical ensemble is introduced in order to establish the exact correspondence between the probability density on the spatial configurations and the quantum distribution, that is the squared modulus of the wave-function. In (...)

    A Locally Deterministic, Detector-Based Model of Quantum Measurement.Brian R. La Cour - 2014 - Foundations of Physics 44 (10):1059-1084.
    This paper describes a simple, causally deterministic model of quantum measurement based on an amplitude threshold detection scheme. Surprisingly, it is found to reproduce many phenomena normally thought to be uniquely quantum in nature. To model an \(N\) -dimensional pure state, the model uses \(N\) complex random variables given by a scaled version of the wave vector with additive complex noise. Measurements are defined by threshold crossings of the individual components, conditioned on single-component threshold crossings. The resulting detection probabilities match (...)

    Einsteinian gravity, of which Newtonian gravity is a part, is fraught with the problem of singularity that has been established as a theorem by Hawking and Penrose. The _hypothesis_ that founds the basis of both Einsteinian and Newtonian theories of gravity is that bodies with unequal magnitudes of masses fall with the same acceleration under the gravity of a source object. Since, the Einstein’s equations is one of the assumptions that underlies the proof of the singularity theorem, therefore, the above (...)

    The cognitive science of religion (CSR) was born from dissatisfaction with traditional interpretative accounts of religious symbolism and with the doctrine of the primacy of texts. The theories, methods, and findings of the cognitive sciences provide means for escaping the interpretative circling the former entails and for addressing the myriad nontextual religious phenomena for which the latter is ill‐suited. Whatever else each affirms, all of the pioneering theorists in CSR agree that religions involve cultural arrangements that engage ordinary cognitive systems, (...)

    Our animal condition and social construction.Jorge A. Colombo (ed.) - 2019 - New York, USA: NOVA Science Publisher.
    Which and how much of our current drives –individually and as a global community– are driven by ancestral, inherited traits or imprinted on our animal condition? An attempt to approximate this intriguing query is explored here. It pertains to our identity, social constructions, and our ecological interaction. The origin of our species has its roots in ancestral habits, behaviors and a survival drive, transformed from changing environmental conditions.

    Lebensunwertes Leben: Roots and Memory of Aktion T4.Erika Silvestri - 2019 - Conatus 4 (2):65.
    What the Nazis called Aktion T4 was a euthanasia program, officially started on August 18th, 1939. The registration operations for individuals with physical or mental handicaps were followed by forced sterilization and transfer to clinics organized to kill. In this article, I try to explain the mechanisms that allowed the memory of Aktion T4 to be preserved and passed from one generation to the next; memories of the “merciful death” of approximately 70,000 “lives unworthy of life,” that find themselves embedded (...)

    Television “news grazers”: Who they are and what they (don’t) know.Stephen Earl Bennett, Staci L. Rhine & Richard S. Flickinger - 2008 - Critical Review: A Journal of Politics and Society 20 (1-2):25-36.
    Between 1998 and 2006, a new style of television news consumption was born: “news grazing.” With remote control devices in hand, “grazers” flip through TV news channels in order to find interesting news stories. Approximately three‐fifths of the public graze, and this group tends to be younger than non‐grazers. Grazers are less likely than the rest of the public to follow “hard” news about politics and economics, and, not surprisingly, they are even less knowledgeable about public affairs than most people (...)

  43. Object-Oriented France: The Philosophy of Tristan Garcia.Graham Harman - 2012 - Continent 2 (1):6-21.
    continent. 2.1 (2012): 6–21. The French philosopher and novelist Tristan Garcia was born in Toulouse in 1981. This makes him rather young to have written such an imaginative work of systematic philosophy as Forme et objet , 1 the latest entry in the MétaphysiqueS series at Presses universitaires de France. But this reference to Garcia’s youthfulness is not a form of condescension: by publishing a complete system of philosophy in the grand style, he has already done what none of us (...)

    Fluctuations in the dynamics of single quantum systems.Anton Amann & Harald Atmanspacher - 1998 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 29 (2):151-182.
    The traditional formalism of quantum mechanics is mainly used to describe ensembles of identical systems (with a density-operator formalism) or single isolated systems, but is not capable of describing single open quantum objects with many degrees of freedom showing pure-state stochastic dynamical behaviour. In particular, stochastic 'line-migration' as in single-molecule spectroscopy of defect molecules in a molecular matrix is not adequately described. Starting with the Bohr scenario of stochastic quantum jumps (between strict energy eigenstates), we try to incorporate more general (...)

    Democratic Practice after the Revolution: The Case of Portugal and Beyond.Robert M. Fishman - 2011 - Politics and Society 39 (2):233-267.
    This article examines democratic practice after the revolution that brought an end to authoritarian dictatorship in Portugal in April 1974, taking the Portuguese case as an opportunity to theorize democratic practice and historical processes that shape its emergence. The argument stresses the distinctive features of democracy born in social revolution and the explanatory role of the partial inversion of social hierarchies and remaking of cultural repertoires in social revolutionary settings. The Portuguese case is compared to its larger neighbor, Spain, which (...)

    Realistic Experiments for Measuring the Wave Function of a Single Particle.S. Nussinov - 1998 - Foundations of Physics 28 (6):865-880.
    We suggest scattering experiments which implement the concept of “protective measurements” allowing the measurement of the complete wave function even when only one quantum system (rather than an ensemble) is available. Such scattering experiments require massive, slow, projectiles with kinetic energies lower than the first excitation of the system in question. The results of such experiments can have a (probabilistic) distribution (as is the case when the Born approximation for the scattering is valid) or be deterministic (in a semiclassical (...)

    AMA Issues Statement on Anencephalics as Living Organ Donors.B. R. - 1995 - Journal of Law, Medicine and Ethics 23 (3):296-297.
    On May 24, 1995, the American Medical Association Council on Ethical and Judicial Affairs issued a rather controversial opinion that it is ethically permissible to use anencephalic infants as living organ donors. Approximately 1,000 to 2,000 infants are born each year in the United States with anencephaly, a congenital birth defect whereby the infant has no forebrain and cerebrum. Without higher brain functions, the infants can never experience consciousness, thoughts, emotions, or pain. Fewer than half survive more than a day, (...)

    The Spartan Rhetra in Plutarch Lycurgus vi B. The Eynomla of Tyrtaios.H. T. Wade-Gery - 1944 - Classical Quarterly 38 (1-2):1-.
    Plutarch concludes his chapter on the Rhetra with six lines of Tyrtaios: φοβου κοςσαντες Πυθωνθεν οκαδ' νεικαν1 μαντεας τε θεο κα τελεντ' πεα ρχειν μν βουλῦς θεοτιμτους βασιλας οσι μλει Σπρτας μερεσσα πλις πρεσβτας τε γροντας, πειτα δ δημτας νδρας πθεαις τραις ντααπαμειβομνους. These lines are quoted to confirm Plutarch's statement, that the Kings who added the last clause to the Rhetra ‘persuaded the city [to accept this addition] on the grounds that it was part of the God's command'. On (...)
