The exploration of chemical periodicity over the past 250 years led to the development of the Periodic System of Elements and demonstrates the value of vague ideas that ignored early scientific anomalies and instead allowed for extended periods of normal science where new methodologies and concepts are developed. The basic chemical element provides this exploration with direction and explanation and has shown to be a central and historically adaptable concept for a theory of matter far from the reductionist frontier. This (...) is explored in the histories of Prout’s hypothesis, Döbereiner Triads, element inversions necessary when ordering chemical elements by atomic weights, and van den Broeck’s ad-hoc proposal to switch to nuclear charges instead. The development of more accurate methods to determine atomic weights, Rayleigh and Ramsey’s gas separation and analytical techniques, Moseley’s X-ray spectroscopy to identify chemical elements, and more recent accelerator-based cold fusion methods to create new elements at the end of the Periodic Table point to the importance of methodological development complementing conceptual advances. I propose to frame the crossover from physics to chemistry not as a loss of accuracy and precision but as an increased application of vague concepts such as similarity which permit classification. This approach provides epistemic flexibility to adapt to scientific anomalies and the continued growth of chemical compound space and rejects the Procrustean philosophy of reductionist physics. Furthermore, it establishes chemistry with its explanatory and operational autonomy epitomized by the periodic system of elements as a gateway to other experimental sciences. (shrink)

In explaining human actions, scholars and laypeople alike employ explanatory devices such as ‘motives’. This paper critically reevaluates the relationship between ‘professional’ and ‘lay’ invocations of motive, proposing a general reorientation of theory and research. This reorientation emphasizes the mundane ‘practical grammar’ of motives, and argues that motive deployment is inextricably tied to deviance, and therefore irremediably moral. It is argued, therefore, that motives should serve as a topic for scholarship, not a resourcefor scholarly use. Several landmark theories of motives, (...) deviance, and explanations are critically reviewed from the proposed vantage. Finally, a brief survey of similarly-minded work is offered, focussing on ethnomethodological arguments and findings, as illustrations of the heuristic power and promise of the outlined approach.

Dada continues to attract a small following among scholars, but has perhaps not yet been recognized as providing invaluable insight into the underlying functions and potentials of culture generally. This article explores the nature and theoretical import of Dada, and two radically different visions of culture as they might try to accommodate and explain Dada. Models of culture taken from Bourdieu and Nietzsche are brought to bear, first on Dada, and then on each other, with the aim of developing a (...) theoretically informed understanding of Dada, and also demonstrating the practical, political and philosophical difficulties involved in choosing between a conflict model of culture and an `existential' model. Ultimately, both models are found to be helpful but insufficient at providing an adequate account of Dada, and it is suggested that present models of cultural analysis can benefit by revisiting both Dada and Nietzsche, trying to incorporate their insights and critically evaluate their visions of culture.

Microscopy allows us to observe objects we cannot see with our eyes alone. With a light microscope, we can distinguish objects at the scale of the wavelengths of visible light just under a micrometer. Around 1870 Ernst Abbe, who laid the foundation of modern optics, suggested that the resolution of a microscope would improve by using some yet-unknown radiation with shorter wavelengths than visible light, that is, below 390 nanometers (1 nm = 10−9 m). Electrons can have wavelengths near 1 (...) picometer (1 pm = 10−12 m) and should therefore allow atoms to be distinguished since they are typically at least a few hundred pm apart. In this oversimplified view, further decreasing the wavelength of the radiation should allow us to increase the resolution of electron microscopy even more. However, this can only be done by increasing the energy of the radiation, which would ultimately destroy the samples. Other factors also affect the resolution of electron microscopes, among them non-ideal imaging properties of electromagnetic lenses, which result in false images. It took more than half a century to understand and control these aberrations and separate objects less than 1 Ångstrom (1 Å = 10−10 m) apart. (shrink)

Social theory remains puzzled by the relation between practices and structures, or the link between ‘micro’ and ‘macro’. Grand theorists including Giddens and Bourdieu have gained distinction for their writings on these questions, trying to marry insights and concerns of a ‘micro’ sociological nature with traditional ‘macro’ structural questions including inequality, power relations, and social reproduction. These theorists arguably fail, however, in their attempts to move social theory beyond traditional dualisms. Relevant but neglected contributions from ethnomethodology are introduced and compared (...) to the work of Giddens and Bourdieu in an attempt to identify and outline an approach to practices and structures that more reliably avoids problems of dualism and reification, and at the same time offers an understanding of structures and their relations to practices that can be much more closely grounded in empirical studies. Key Words: micro-macro link • reification • ethnomethodology • Pierre Bourdieu • Jeff Coulter. (shrink)

Le mouvement Occupons nous a démontré qu’il était fort côté tactique. Le moment est venu de prouver qu’il a aussi une stratégie.

The issue of whether formal reasoning or a computing-intensive approach is the most efficient manner to address scientific questions is the subject of some considerable debate and pertains not only to the nature of the phenomena and processes investigated by scientists, but also the nature of the equation and algorithm objects they use. Although algorithms and equations both rely on a common background of mathematical language and logic, they nevertheless possess some critical differences. They do not refer to the same (...) level of symbolization, as equations are based on integrated concepts in a denotational manner, while algorithms specifically break down a complex problem into more elementary operations, in an operational manner. They may therefore be considered as suited to the representation of different phenomena. Specifically, algorithms are by nature sufficient to represent weak emergent phenomena, but not strong emergent patterns, while equations can do both. Finally, the choice between equations and algorithms are by nature sufficient to represent weak emergent phenomena, but not strong emergent patterns, while equations behave conversely. We propose a simplified classification of scientific issues for which both equation- and/or algorithm-based approaches can be envisaged, and discuss their respective pros and cons. We further discuss the complementary and sometimes conflicting uses of equations and algorithms in a context of ecological theory of metapopulation dynamics. We finally propose both conceptual and practical guidelines for choosing between the alternative approaches. (shrink)

This paper examines Alfred Schutz’s insights on types and typification. Beginning with a brief overview of the history and meaning of typification in interpretive sociology, the paper further addresses both the ubiquity and the necessity of typification in social life and scientific method. Schutz’s contribution itself is lacking in empirical application and grounding, but examples are provided of ongoing empirical research which advances the understanding of types and typification. As is suggested by illustrations from scholarship in the social studies of (...) social science, studies of social identity associated with membership categorization analysis, and constructionist social problems theory, typification can be found to be central to social research whether it is taken up as a largely unacknowledged resource or whether it is addressed by different names. The overview and illustrations suggest the continuing, widespread, and indeed foundational relevance of Schutz’s insights into types and typification. (shrink)
