    Sequential Time Theory: Metrological Completion of Relativity.Teruhito Kojima - manuscript
    Sequential Time Theory (STT) defines time as a metrological quantity realized by operational procedures (record, count, resolution), distinct from the coordinate time parameter in spacetime geometry. Starting from the primitive definition Δτ(n)=n k ΔQ_unit, STT internalizes time metrology (L2) and treats spacetime geometry (L1) as a representation of protocol constraints, rendering block-universe interpretations optional rather than required for physical derivations. Physics is reframed as STT-Core + Bridge axioms + Θ_sys, where Θ_sys is an explicit, auditable bundle of system-specific auxiliary (...)

    Metrological Theory of Time: Structural Uncalibratability between Irreversible Decay and Reversible Cycles.Masahiro Aimi - manuscript
    Time standards are not merely descriptions of nature; they are socio-technical infrastructures and protocols that enable measurement, synchronization, and institutional coordination. This paper reconceives “time” not as a universal dimension or physical entity, but as a metrological interface that operates only by coupling two heterogeneous kinds of physical processes. It distinguishes (a) irreversible thermodynamic processes (entropy increase, aging, deterioration, diffusion) and (b) dynamical processes that, under idealization, are reversible and periodic (rotation, oscillation), and analyzes the structural problem inherent in using (...)

  3. Beyond the metrological viewpoint.Jean Baccelli - 2020 - Studies in History and Philosophy of Science Part A 1 (C):56-61.
    The representational theory of measurement has long been the central paradigm in the philosophy of measurement. Such is not the case anymore, partly under the influence of the critique according to which RTM offers too poor descriptions of the measurement procedures actually followed in science. This can be called the metrological critique of RTM. I claim that the critique is partly irrelevant. This is because, in general, RTM is not in the business of describing measurement procedures, be it in idealized (...)

  4. Sequential Time Theory: A Metrological Reconstruction of Time and the Resolution of the Arrow of Time Paradox.Teruhito Kojima - manuscript
    This monograph presents Sequential Time Theory (STT), an operational reconstruction of physical time based on the counting of discrete, distinguishable events. The framework resolves classical paradoxes surrounding the arrow of time, relativistic time dilation, and quantum measurement by treating time as a constructed variable rather than an ontological dimension. STT argues that irreversibility arises logically from event accumulation, that relativistic effects reflect delays in event generation, and that quantum collapse represents the registration of discrete physical changes. The theory offers a (...)

    Sequential Time Theory: From Time Metrology to Higgs Mechanism - A Metrological Audit of the Standard Model.Teruhito Kojima - manuscript
    Sequential Time Theory (STT) provides a metrological foundation for physics, defining time through operational procedures rather than as a geometric coordinate. STT CR (Metrological Completion of Relativity) established a formal framework: Physics = (STT-Core -> Bridge -> L1) -> Θ_sys Physical Systems, where L1 is the formal language of dynamics, L2 (STT-Core) is the operational definition of time, and Θ_sys is the mapping rule to specific physical systems. This paper applies this framework to audit the Standard Model (Θ_SM), focusing on (...)

  6. Sequential Time Theory, Volume 2: Quantum Metrology and the Relativity of Observation Scale.Teruhito Kojima - manuscript
    This paper extends the temporal concept of Sequential Time Theory (STT) to the problem of metrology in the quantum domain. In STT, a time interval Δt is constructed by a counter n representing the number of realizations of a standard displacement ΔQ_unit, while time t serves as a coordinate label assigned to this sequence. STT explicitly posits that "time is a scaling of physical change" and that "time is constructed solely by clock phenomena subject to the same conditions within (...)

  7. Calibrating the theory of model mediated measurement: metrological extension, dimensional analysis, and high pressure physics.Mahmoud Jalloh - 2024 - European Journal for Philosophy of Science 14 (40):1-32.
    I argue that dimensional analysis provides an answer to a skeptical challenge to the theory of model mediated measurement. The problem arises when considering the task of calibrating a novel measurement procedure, with greater range, to the results of a prior measurement procedure. The skeptical worry is that the agreement of the novel and prior measurement procedures in their shared range may only be apparent due to the emergence of systematic error in the exclusive range of the novel measurement procedure. (...)

  8. (1 other version)Understanding Data Uncertainty.Alisa Bokulich & Wendy Parker - forthcoming - Studies in History and Philosophy of Science.
    Scientific data without uncertainty estimates are increasingly seen as incomplete. Recent discussions in the philosophy of data, however, have given little attention to the nature of uncertainty estimation. We begin to redress this gap by, first, discussing the concepts and practices of uncertainty estimation in metrology and showing how they can be adapted for scientific data more broadly; and second, advancing five philosophical theses about uncertainty estimates for data: they are substantive epistemic products; they are fallible; they can be (...)

  9. Calibration, Coherence, and Consilience in Radiometric Measures of Geologic Time.Alisa Bokulich - 2020 - Philosophy of Science 87 (3):425-456.
    In 2012, the Geological Time Scale, which sets the temporal framework for studying the timing and tempo of all major geological, biological, and climatic events in Earth’s history, had one-quarter of its boundaries moved in a widespread revision of radiometric dates. The philosophy of metrology helps us understand this episode, and it, in turn, elucidates the notions of calibration, coherence, and consilience. I argue that coherence testing is a distinct activity preceding calibration and consilience, and I highlight the value (...)

  10. Understanding scientific types: holotypes, stratotypes, and measurement prototypes.Alisa Bokulich - 2020 - Biology and Philosophy 35 (5):1-28.
    At the intersection of taxonomy and nomenclature lies the scientific practice of typification. This practice occurs in biology with the use of holotypes (type specimens), in geology with the use of stratotypes, and in metrology with the use of measurement prototypes. In this paper I develop the first general definition of a scientific type and outline a new philosophical theory of types inspired by Pierre Duhem. I use this general framework to resolve the necessity-contingency debate about type specimens in (...)

  11. Messung und Invarianz – ein Beitrag zum Metrologischen Strukturenrealismus.Alexander Ehmann - 2013 - Philosophia Naturalis 50 (2):215-251.
    [ENGLISH] The present article is a contribution to the development of metrological structural realism. This position of philosophy of science goes back to Matthias Neuber, who introduces it as a third variation of the main structural realisms: epistemic structural realism and ontic structural realism. Here, Neuber attempts to tackle the problems of OSR and ESR while preserving their respective strengths. Of central importance to his approach, are the concepts of invariance, structure and, especially, measurement. Starting from Eino Kaila’s „non-linguistic, realist (...)

  12. Playing Ozma Games with Kibble Balances: a new Defence of Absolutism about Mass.Julien Nicolas Tricard - forthcoming - British Journal for the Philosophy of Science.
    This paper engages with the metaphysical debate between Absolutism and Comparativism about mass, addressing the question of whether massive objects possess their masses intrinsically (as absolute magnitudes) or only relationally, through their mass relations to other objects. In the current debate, comparativists argue that the dimensional nature of mass renders absolute magnitudes undetectable and redundant, forcing absolutists to rely on arguments about the dynamic relevance of absolute masses in physical laws. I advance a novel defence of Absolutism by appealing to (...)

    In the last few decades the role played by models and modeling activities has become a central topic in the scientific enterprise. In particular, it has been highlighted both that the development of models constitutes a crucial step for understanding the world and that the developed models operate as mediators between theories and the world. Such perspective is exploited here to cope with the issue as to whether error-based and uncertainty-based modeling of measurement are incompatible, and thus alternative with one (...)

  14. Dimensional Analysis: Essays on the Metaphysics and Epistemology of Quantities.Mahmoud Jalloh - 2023 - Dissertation, University of Southern California
    This dissertation draws upon historical studies of scientific practice and contemporary issues in the metaphysics and epistemology of science to account for the nature of physical quantities. My dissertation applies this integrated HPS approach to dimensional analysis—a logic for quantitative physical equations which respects the distinct dimensions of quantities (e.g. mass, length, charge). Dimensional analysis and its historical development serve both as subjects of study and as a sources for solutions to contemporary problems. The dissertation consists primarily of three related (...)

  15. Prnicpia Physica: From Mass Factorization to Knot Light, We Are.Khaled Bouzaine - manuscript
    We present a scalar-tensor framework for gravitation derived from Anisotropic Weyl Symmetry (AWS), a local scaling invariance that distinguishes between temporal and spatial conformal weights. This symmetry imposes a structural factorization of the intrinsic mass parameter into two relational channels: an energy channel (mE ) governing quantum phases and time dilation, and an inertia channel (mI ) governing spatial propagation and kinetic response. We derive the Ward identity γI − γE = 4γS , demonstrating that this factorization is protected by (...)

  16. Can Measurement be Entirely Quantum?Lucy Mason - manuscript
    I will look at Bohr's contentious doctrine of classical concepts - the claim that measurement requires classical concepts to be understood - and argue that measurement theory supports a similar conclusion. I will argue that representing a property in terms of a metric scale, which marks a shift from the empirical process of measurement to the informational output, introduces the inherently classical assumption of definite states and precise values, thus fulfilling Bohr's doctrine. I examine how realism about metric scales implies (...)

  17. From the philosophy of measurement to the philosophy of classification: Generalizing the problem of coordination and historical coherentism.François Papale - 2024 - Studies in History and Philosophy of Science Part A 106 (C):1-11.
    The objective of this paper is twofold. First, I present a framework called historical coherentism (Chang, 2004; Tal, 2016; Van fraassen 2008) and argue that it is the best epistemological framework available to tackle the problem of coordination, an epistemic conundrum that arises with every attempt to provide empirical content to scientific theories, models or statements. Second, I argue that the problem of coordination, which has so far been theorized only in the context of measurement practices (Reichenbach, 1927; Chang, 2001; (...)

  19. La valeur de l'incertitude : l'évaluation de la précision des mesures physiques et les limites de la connaissance expérimentale.Fabien Grégis - 2016 - Dissertation, Université Sorbonne Paris Cité Université Paris.Diderot (Paris 7)
    Abstract : A measurement result is never absolutely accurate: it is affected by an unknown “measurement error” which characterizes the discrepancy between the obtained value and the “true value” of the quantity intended to be measured. As a consequence, to be acceptable a measurement result cannot take the form of a unique numerical value, but has to be accompanied by an indication of its “measurement uncertainty”, which enunciates a state of doubt. What, though, is the value of measurement uncertainty? What (...)

  20. After economics' "discovery" of homo socialis: Decolonial vigilance and interpretive collaboration.Carlos Palacios - 2024 - Global Perspectives 5 (1):1-20.
    Current intellectual calls for more socially minded governance often resort to the authority of the experimental and behavioral economists who have provided uncontroversial evidence for the generalized existence of a Homo socialis. For a qualitative social researcher, the narrative of a “discovery” makes little sense. This article provides a more meaningful account of the experimental rationale of prosocial preferences research, interrogating, from a “decolonial” theoretical perspective, the epistemic and normative implications of a method that persuasively claims to have challenged the (...)

    We reconstruct Kuhn’s philosophy of measurement and data paying special attention to what he calls the “fifth law of thermodynamics”. According to this "law," there will always be discrepancies between experimental results and scientists’ prior expectations. The history of experiments to determine the values of the fundamental constants offers a striking illustration of Kuhn’s fifth law of thermodynamics, with no experiment giving quite the expected result. We highlight the synergy between Kuhn’s view and the systematic project of iteratively determining the (...)

    At first sight, measurement might appear to be a natural candidate for a scientific practice that is value-free. This chapter reviews prominent arguments supporting the opposite view, i.e., that values play significant roles in measurement practices. Some of the arguments reviewed concern background assumptions underlying the pursuit of measurement and shaping its character. Other arguments focus on the various socially significant consequences of measurement practices (or aspects thereof), while still others focus on the content of the concepts being measured and (...)

  24. Maxwell, Peirce, and Planck: The Quest for Absolute Measurement and Absolute Reality.Mahmoud Jalloh - manuscript
    People are often interested in physics due to its purported objectivity. It aims to truly be a study of nature (φύσεις) in itself. On the other hand, physics is a human construct, a language we use to describe the world as we experience it. In our quest for absolute reality, then, it seems that we must rid our description of the world of all subjectivity. This lecture concerns part of a story of such an attempt: the quest for absolute measurement. (...)

  25. Structured Resonance Dynamics — Empirical Transition and Verification Protocols.Devin Bostick - manuscript
    This paper defines an empirical standard for testing the Structured Resonance Dynamics (SRD) corpus. Six gates map SRD invariants to measurable observables under deterministic replay with fixed-point Q32 numerics. Proof bundles (header.json, steps.jsonl, graph.json) are hashed (SHA256) and Ed25519-signed to ensure bit-identical reproduction. The protocol provides preregistration schemas, regression targets (R² ≥ 0.95), confidence-interval routines, and an explicit kill-switch table that suspends claims upon replicated failure. Gates cover drift-volume scaling, an E_eff-based floor postulate, chirality collapse, fine-structure stability, cosmological lensing parity, (...)

    Wepresent a geometric reformulation of Planck units and fundamental constants based on an integer-valued unit-number map θ and a small set of dimensionless gen erators. Physical quantities are represented by dimensionless geometric objects con structed from (π,Ω) and a dimensionless fine-structure parameter α, while local unit systems (e.g. SI) enter only through two dimensioned scalars (r,v) that translate the geometry into conventional units. The framework yields a unified table of con stants expressible in the form xθipyq with i = π2Ω15, (...)

    Research and engineering in the quantum domain involve long chains of activity involving theory development, hypothesis formation, experimentation, device prototyping, device testing, and many more. At each stage multiple paths become possible, and of the paths pursued, the majority will lead nowhere. Our quantum metascience approach provides a strategy which enables all stakeholders to gain an overview of those developments along these tracks, that are relevant to their specific concerns. It provides a controlled vocabulary, built out of terms that are (...)
