This paper examines the epistemological implications of a particular underdetermination problem from geophysics, with an emphasis on understanding how the scientists themselves tried to deal with the problem. The problem is from the highly influential work of the geophysicists Backus and Gilbert in the late 60’s, who were trying to determine the internal structure of the Earth using seismic waves. I find that actual underdetermination problems can be vastly complex, with different sources of underdetermination having different epistemological implications. A (...) better understanding of actual cases of underdetermination is needed before we can make epistemological conclusions based on underdetermination. (shrink)

ABSTRACT The contribution of amateur scientists to the International Geophysical Year (IGY) was substantial, especially in the arena of spotting artificial satellites. This article examines how Fred L. Whipple and his colleagues recruited satellite spotters for Moonwatch, a program for amateur scientists initiated by the Smithsonian Astrophysical Observatory (SAO) in 1956. At the same time, however, the administrators with responsibility for the IGY program closely monitored and managed—sometimes even contested—amateur participation. IGY programs like Moonwatch provided valuable scientific information and gave (...) amateurs opportunities to contribute actively to the research of professional scientists. Moonwatch, which operated until 1975, eventually became the public face of a vast satellite‐tracking network that expanded the SAO’s global reach and helped further Whipple’s professional goals. Understanding amateurs’ interactions with the professional science community enables us better to understand the IGY as a phenomenon that enlisted broad participation and transcended traditional boundaries between professional and amateur scientists.

Did industry and commerce affect the concepts, values and epistemic foundations of different sciences? If so, how and to what extent? This book suggests that the most significant influence of industry on science in the two case studies treated here had to do with the issue of realism. However, what led physicists and engineers to adopt realist attitudes? This book suggests that a new kind of realism --a realism of social and cultural origins- is the answer. The book has two (...) parts: while Part I focuses on the study of the ionosphere and how the British radio industry affected ionospheric physics, Part II focuses on the study of the Earth's crust and how the American oil industry affected crustal seismology.

What makes any investigative field a scientific discipline? This article argues that disciplines are ever-changing frameworks within which scientific activity is organised. Moreover, disciplinarity is not a yes or no proposition: scientific activities may achieve degrees of identity development. Degree of consensus is the key, and consensus on many questions (conceptual, methodological, institutional, and social) varies among sciences. Lastly, disciplinary development is non-teleological. Disciplines pass through no regular stages on their way from immature to mature status, designations articulated within the (...) rhetoric of discipline formation. Scientists assemble disciplines using many elements: phenomena, methods, instruments, theories, analytical techniques, and institutional tools such as journals, government bureaus, and university positions. Scientists created geophysics during the nineteenth and twentieth centuries through such a combination. Whether geophysics became a discipline depends on how discipline is defined. (shrink)

SummaryIn 1865, Spanish Jesuits founded the Manila Observatory, the earliest of the Far East centres devoted to typhoon and earthquake studies. Also on Philippine soil and under the direction of the Jesuits, in 1884 the Madrid government inaugurated the first Meteorological Service in the Spanish Kingdom, and most probably in the Far East. Nevertheless, these achievements not only went practically unnoticed in the historiography of science, but neither does the process of geophysical dissemination that unfolded fit in with the two (...) types of transmitter of knowledge identified by historians in the missionary diffusion of the exact sciences in colonial contexts. Rather than regarding science as merely a stimulus to their functionary and missionary tasks, Spanish Jesuits used their overseas posting to produce and publish original research –– a feature that would place them within the typology of the ‘seeker’ rather than the ‘functionary’ (in stark contrast to what the standard typology sustains). This paper also analyses examples of synergies between science, education and trade, which denotes, inter alia, the existence of a broad and solid educational structure in the Manila Mission that sustained the strength of research enterprise.

Whereas literature on satellites and outer space exploration has usually been dominated by vision, humankind’s initial encounter with the Earth’s first artificial satellite, Sputnik I, was overwhelmingly sonic. Tracking was originally enabled by the signal continuously transmitted by its radio beacon. Embedded in the International Geophysical Year (IGY) citizen science programs, radio amateurs played a crucial role in receiving the signal and assisting professional scientists in tracking the satellite in its initial phases. Their established existence as a distinctive worldwide community (...) of skilled operators and experimenters made hams special allies to IGY scientists and, in many respects, set them apart from other groups of amateur scientists. This essay focuses on radio amateurs’ practices and spaces of listening to Sputnik within the wider framework of the IGY. In transcending national and terrestrial boundaries, Sputnik’s signal shaped new spatialities at a variety of scales: from the macroscales of the globe and outer space to the intimate microscale of the domestic radio shack. Focusing on radio amateurs’ personal experiences and on the invisible agencies of Sputnik’s signal, the essay uses sound as a way into the sociocultural, political, and scientific importance of the IGY. More broadly, it contributes to a multisensory history (and geography) of science. (shrink)

The present authors have given a mathematical model of Mach's principle and of the Mach–Einstein doctrine about the complete induction of the inertial masses by the gravitation of the universe. The analytical formulation of the Mach–Einstein doctrine is based on Riemann's generalization of the Lagrangian analytical mechanics (with a generalization of the Galilean transformation) on Mach's definition of the inertial mass and on Einstein's principle of equivalence. All local and cosmological effects—which are postulated as consequences of Mach's principle by C. (...) Neumann, Mach, Friedländer and Einstein—result from the Riemannian dynamics with the Mach–Einstein doctrine. In celestial mechanics it follows, in addition, Einstein's formula for the perihelion motion. In cosmology, the Riemannian mechanics yields two models of an evolutionary universe with the expansion lows R ~ t or R ~ t2. In this paper, secular consequences of the Mach–Einstein doctrine are examined concerning palaeogeophysics and celestial mechanics. The research predicted secular decrease of the Earth's flattening and secular acceleration of the motion of the Moon and of the planets. The numerical values of this secular effect agree very well with the empirical facts. In all cases, the secular variation $\dot{\alpha}$ of the parameter α is the order of magnitude $\dot{\alpha}=-H_0 \alpha$ , where H0 is the instantaneous value of the Hubble constant: $H_0 =\left({\dot{R}/R} \right)_0 \approx \left( {0.5-1.0} \right) \times 10^{-10}a^{-1}$ . The relation of the secular consequences of the Mach–Einstein doctrine to those of Dirac's hypothesis on the expanding Earth, and to Darwin's theory of tidal friction are also discussed. (shrink)

Summary Analogue models are actual physical setups used to model something else. They are especially useful when what we wish to investigate is difficult to observe or experiment upon due to size or distance in space or time: for example, if the thing we wish to investigate is too large, too far away, takes place on a time scale that is too long, does not yet exist or has ceased to exist. The range and variety of analogue models is too (...) extensive to attempt a survey. In this article, I describe and discuss several different analogue model experiments, the results of those model experiments, and the basis for constructing them and interpreting their results. Examples of analogue models for surface waves in lakes, for earthquakes and volcanoes in geophysics, and for black holes in general relativity, are described, with a focus on examining the bases for claims that these analogues are appropriate analogues of what they are used to investigate. A table showing three different kinds of bases for reasoning using analogue models is provided. Finally, it is shown how the examples in this article counter three common misconceptions about the use of analogue models in physics. (shrink)

A third electrical geophysical prospection campaign conducted at Philippi in September 2001 added 9 ha to the area already covered. The interpretation of the results in the West part of the town shows that it was organised in three rows of insulae of the same module (ca. 27 x 83 m). The first row on the south side of the principal axis, which is the Via Egnatia, comprises several monumental groups, induding a large Early Christian basilica and a double stoa (...) along a small public square. The second and third rows are more difficult to interpret because of disturbances associated with the presence of a fortified Byzantine redoubt around the marsh Gate. A comparison of these geophysical data with the records of the French excavations, the epigraphic and photographie evidence and a topographical survey, has considerably clarified their interpretation.

If the Anthropocene represents a new epoch of thought, it also represents a new form of materiality and historicity for the human as strata and stratigrapher of the geologic record. This collision of human and inhuman histories in the strata is a new formation of subjectivity within a geologic horizon that redefines temporal, material, and spatial orders of the human. I argue that the Anthropocene contains within it a form of Anthropogenesis – a new origin story and ontics for man (...) – that radically rewrites material modes of differentiation and concepts of life, from predominantly biopolitical notions of life toward an understanding of life’s geophysical origination. Here, I use the term Anthropogenesis to suggest that two things explicitly happen in the nomination of the Anthropocene: 1) the production of a mythic Anthropos as geologic world-maker/destroyer of worlds, and 2) a material, evolutionary narrative that re-imagines human origins and endings within a geologic rather than an exclusively biological context. In contrast to the homogeneous geomorphizing of the Anthropocene, I suggest that socializing the strata needs a more nuanced notion of ‘geologic life’ that challenges the construction of the Anthropocene as an undifferentiated social stratification.

This book is inspired by a German theoretical physicist, Sabine Hossenfelder’s publication: “Lost in Mathematics”. Her book seems to question highly mathematical and a lot of abstraction in the development of physics and cosmology studies nowadays. There is clear tendency that in recent decades, the physics science has been predominated by such an advanced mathematics, which at times sounding more like acrobatics approach to a reality. Through books by senior mathematical-physicists like Unzicker and Peter Woit, we know that the answer (...) of TOE is not in superstring theories or other variations of such 26 dimensional bosonic string theory, of which none of those theories survived experimental test, but perhaps in low dimensional physics. As Alexander Unzicker suggests, perhaps it is more advisable to consider rotation in 3D space (known as SO3), or a kind of superfluid vortices version of gravitation theory. We can also reconsider proposition by the late Prof F. Winterberg (formerly professor at Univ. Nevada, Reno), that it is most likely that superfluid phonon roton theory in 3D can replace the entire superstring theories. While we don’t explore yet implications of his model to particle physics, we discuss here some published papers at several journals in the past few years. (shrink)

It is widely supposed that the scientists in any field use identical standards for evaluating theories. Without such unity of standards, consensus about scientific theories is supposedly unintelligible. However, the hypothesis of uniform standards can explain neither scientific disagreement nor scientific innovation. This paper seeks to show how the presumption of divergent standards (when linked to a hypothesis of dominance) can explain agreement, disagreement and innovation. By way of illustrating how a rational community with divergent standards can encourage innovation and (...) eventually reach consensus, recent developments in geophysics are discussed at some length.

"The book provides an excellent historical summary of the debates over continental drift theory in this century." —Contemporary Sociology "This is a useful discussion of the way that science works. The book will be of value to philosophers of science... " —Choice "... will find an important place in university and department libraries, and will interest afficionados of the factual and intellectual history of the earth sciences." —Terra Nova "... an excellent core analysis... " —The Times Higher Education Supplement "... (...) an ambitious and important contribution to the new sociology of science." —American Journal of Sociology "... Stewart's book is a noble effort, an interesting and readable discussion, and another higher notch on the scoreboard of critical scholarship that deserves wide examination and close attention." —Geophysics This fascinating book describes the rise and fall and rebirth of continental drift theory in this century. It uses the recent revolution in geoscientinsts' beliefs about the earth to examine questions such as, How does scientific knowledge develop and change? The book also explores how well different perspectives help us to understand revolutionary change in science. (shrink)

During the course of two campagns in May and November 2000, a large scale geophysical sur- vey combining resistivity and magnetometry studies was carried out over an area of about 5.5 hectares in the southwest corner of the urban area at Philippi. The results achieved the initial goal, which was to identify the limits of the block with the Bath House prior to a resumption of its excavation. They also extended our knowledge of the urban layout of the ancient town (...) and its double orientation and identified the existence and indeed the plans — if not always the fonctions — of several important monuments. Part of the results could be confirmed by observations of the remains visible on the surface, and in particular from a study of the aerial photographs. (shrink)

The proposal of the ‘Anthropocene’ as a new geological epoch where humans represent the dominant natural force has renewed artistic interest in the ‘geopoetic’, which is mobilized by cultural producers to incite changes in personal and collective participation in planetary life and politics. This article draws attention to prior engagements with the geophysical and the political: the work of Simone Weil and of the editors of the Martinican cultural journal Tropiques, Suzanne and Aimé Césaire. Synthesizing the political and scientific shifts (...) in human-world relationships of their time, both projects are set against oppressive or narcissistic materialisms and experiment with the image of the ‘cosmic’ to cultivate a preoccupation not with a tangible materialism but with an intangible one that emphasizes process and connectivity across wide spatial and temporal scales. The writers’ movement between poetics and politics will be used to enquire what kind of socio-political work a contemporary geopoetic could potentially do. (shrink)

Abstract…observations of skylfull pylotts is the onlye waye to bring it in rule; for it passeth the reach of naturall philosophy. – Michael Gabriel, 1576 (Collinson, 1867, p. 30)Abstract The tension between empirical data and formal theory pervades the entire history of geomagnetism, from the Middle Ages up to the present day. This paper explores its early-modern history (1500–1800), using a hybrid approach: it applies a methodological framework used in modern geophysics to interpret early-modern developments, exploring to what extent (...) formal conjectures shaped observation and vice versa. A range of pertinent case studies supports classification of this entire period as proto-scientific, characterised by the initial formation of theories being largely disconnected from observational constraints, and their subsequent evolution being advanced primarily by their empirical falsification, and not necessarily associated with the introduction of an alternative. The few exceptional instances of purely data-driven discovery were essentially due to an improved signal-to-noise ratio. (shrink)

The conventional view of vitamins reflects a diverse group of small molecules that facilitate critical aspects of metabolism and prevent potentially fatal deficiency syndromes. However, vitamins also contribute to the shaping and maintenance of the human phenome over lifecycle and evolutionary timescales, enabling a degree of phenotypic plasticity that operates to allow adaptive responses that are appropriate to key periods of sensitivity (i.e., epigenetic response during prenatal development within the lifecycle or as an evolved response to environmental challenge over a (...) great many lifecycles). Individually, vitamins are important, but their effect is often based on nutrient‐nutrient (vitamin‐vitamin), nutrient‐gene (vitamin‐gene), and gene‐gene interactions, and the environmental influence of shifting geophysical cycles, as well as evolving cultural practices. These ideas will be explored within what I refer to as the “adaptive vitome (vitomics)” paradigm. (shrink)

Future Earth is an evolving international research program and platform for engagement aiming to support transitions toward sustainability. This article discusses processes that led to Future Earth, highlighting its intellectual emergence. I describe how Future Earth has increased space for contributions from the social sciences and humanities despite powerful, long-standing preferences for bio-geophysical research in global environmental research communities. I argue that such preferences nevertheless are deeply embedded in scientific institutions that continue to shape environmental science agendas and, as such, (...) constitute a formidable obstacle that needs to be recognized and countered to bolster efforts at effective societal transformation in the face of sustainability challenges. The analysis draws on two decades of observant participation in environmental research communities in the United States, Europe, Brazil, and elsewhere, including participation in the visioning process that led to Future Earth.

Edited by Richard Grusin of the Center for 21st Century Studies, this is the first book to name and characterize—and therefore consolidate—a wide array of current critical, theoretical, and philosophical approaches to the humanities and social sciences under the concept of the nonhuman turn. Each of these approaches is engaged in decentering the human in favor of a concern for the nonhuman, understood by contributors in a variety of ways—in terms of animals, affectivity, bodies, materiality, technologies, and organic and geophysical (...) systems. The nonhuman turn in twenty-first-century studies can be traced to multiple intellectual and theoretical developments from the last decades of the twentieth century: actor-network theory, affect theory, animal studies, assemblage theory, cognitive sciences, new materialism, new media theory, speculative realism, and systems theory. Such varied analytical and theoretical formations obviously diverge and disagree in many of their assumptions, objects, and methodologies. However, they all take up aspects of the nonhuman as critical to the future of twenty-first-century studies in the arts, humanities, and social sciences. Unlike the posthuman turn, the nonhuman turn does not make a claim about teleology or progress in which we begin with the human and see a transformation from the human to the posthuman. Rather, the nonhuman turn insists (paraphrasing Bruno Latour) that “we have never been human,” that the human has always coevolved, coexisted, or collaborated with the nonhuman—and that the human is identified precisely by this indistinction from the nonhuman.

The rise of the idea of the Anthropocene is promoting multiple reflections on its meaning. As we consider entering this new geological epoch, we realize the pervasiveness of humankind’s deconstruction and reconstruction of the Earth, in both geophysical and discursive terms. As the body of the Earth is marked and reshaped, so is its idea. From a hostile territory to be subjugated and exploited through sovereign commands, the Earth is now reframed as a vulnerable domain in need of protection. The (...) mode of sovereignty, which has accompanied human and legal history and practice during modernity and its project of mastery, is no longer useful. Humanity’s control of the Earth is being reimagined and reconfigured along biopolitical coordinates of thought and action. Biopolitics shifts the focus of power, changes its modalities of interventions, and rearticulates its legitimacy on the idea of taking responsibility for the Earth, for nature. A biopolitical re-orientation of law captures the fundamental aim of caring for nature, of fostering its vital possibilities and of enhancing its productive potential. Yet, biopolitics engulfs nature in its entirety under its framework of control, where protection and subjugation, vulnerability and productivity, life and death are constantly entangled in a reciprocal and inevitable relation of indistinguishability. Sovereignty becomes thus a key modality of biopolitical intervention, when nature is recalcitrant, wild, spontaneous, unpredictable, violent, dangerous. Biopolitics, thus, remains caught in an undecidable dilemma, where in order to protect the Earth, it must subjugate it; to save it, it must condemn it. In this respect, biopolitics remains utterly modern, or as argued by Roberto Esposito, modernity has always been biopolitical, insofar as modernity has emerged as a framework for the protection of life against life’s own excesses. But how can we escape the biopolitical reframing and enframing of the Earth and its total subsumption under its matrix of control? How can we rethink the encounter between law and nature without remaining entangled in the aporetic dilemma of biopolitics? An aesthetics of wonder may offer a way. (shrink)
