Bottoms up: The Standard Model Effective Field Theory from a model perspective.

Experiments in particle physics have hitherto failed to produce any significant evidence for the many explicit models of physics beyond the Standard Model (BSM) that had been proposed over the past decades. As a result, physicists have increasingly turned to model-independent strategies as tools in searching for a wide range of possible BSM effects. In this paper, we describe the Standard Model Effective Field Theory (SM-EFT) and analyse it in the context of the philosophical discussions about models, theories, and (bottom-up) effective field theories. We find that while the SM-EFT is a quantum field theory, assisting experimentalists in searching for deviations from the SM, in its general form it lacks some of the characteristic features of models. Those features only come into play if put in by hand or prompted by empirical evidence for deviations. Employing different philosophical approaches to models, we argue that the case study suggests not to take a view on models that is overly permissive because it blurs the lines between the different stages of the SM-EFT research strategies and glosses over particle physicists' motivations for undertaking this bottom-up approach in the first place. Looking at EFTs from the perspective of modelling does not require taking a stance on some specific brand of realism or taking sides in the debate between reduction and emergence into which EFTs have recently been embedded.

Hilbert's axiomatic method and Carnap's general axiomatics.

This paper compares the axiomatic method of David Hilbert and his school with Rudolf Carnap's general axiomatics that was developed in the late 1920s, and that influenced his understanding of logic of science throughout the 1930s, when his logical pluralism developed. The distinct perspectives become visible most clearly in how Richard Baldus, along the lines of Hilbert, and Carnap and Friedrich Bachmann analyzed the axiom system of Hilbert's Foundations of Geometry­the paradigmatic example for the axiomatization of science. Whereas Hilbert's axiomatic method started from a local analysis of individual axiom systems in which the foundations of mathematics as a whole entered only when establishing the system's consistency, Carnap and his Vienna Circle colleague Hans Hahn instead advocated a global analysis of axiom systems in general. A primary goal was to evade, or formalize ex post, mathematicians' 'material' talk about axiom systems for such talk was held to be error-prone and susceptible to metaphysics.

[An encyclopedia for the empire]. / Eine Enzyklopädie für das Kaiserreich.

In the preface to the universal encyclopedia Die Kultur der Gegenwart (The Culture of the Present), the editor-in-chief Paul Hinneberg places his project--not openly but nevertheless unequivocally--in the tradition of the French Encyclopédie that Diderot and d'Alembert had organized from 1751 until 1765. The attempt to accomplish anew such a large-scale project and, in this way, to win the German Empire the kind of intellectual leadership which the Encyclopédie, in historical retrospect, had achieved for the epoch of Enlightenment, required to convince the leading scholars, scientists, and technicians of the nation to participate in the endeavor and to assemble their contributions under a common systematic agenda through which this universal encyclopedia would distinguish itself from all dictionaries and disciplinary encyclopedias. While the Encyclopédie followed to a large extent an empiricist philosophy, Hinneberg trusted in the integrative function of the concept of culture and the ability of his contributors to elucidate the history of their respective disciplines and to connect them with neighboring fields of culture. The present contributions argues that although, from a philosophical point of view, the historicist tack taken by Hinneberg makes the concept of culture quite blurry, it nevertheless provides enough cohesive structure such that the work, even though unfinished as a consequence of war and inflation, represents a faithful picture of its epoch that Hinneberg understands as an epoch of transition.
