Shadows over Shulamith: Giordano Bruno's De umbris idearum and the Song of Songs

This article focuses on the use of one verse from the Biblical Songs of Songs in central passages of Giordano Bruno's first published book on the art of memory. De umbris idearum [On the Shadows of Ideas] not solely aims at improving mnemonic capacities, it also envisages the preconditions and limits of cognition in Bruno's new inifitist cosmology. Taking relevant scholarly literature on the topic as a point of departure, this contribution presents De umbris in the context of Bruno's philosophy in general; it focuses on Bruno's evocation of Origen's commentary on that passage in the Song of Songs. The article analyzes in detail the reasons for Bruno's subversion of the traditional exegetic tradition that was massively influenced by Origen's spiritualized reading of the Song of Songs. Bruno's misappropriation of the Origen's commentary turns out to be a mise en abyme, a mannerist strategy of representation. It not only reflects the very method that underlies Bruno's art of memory, but is also to be understood as a conscious subversion of exegetic traditions in general

Theory of interlayer exchange interactions in magnetic multilayers

This paper presents a review of the phenomenon of interlayer exchange coupling in magnetic multilayers. The emphasis is put on a pedagogical presentation of the mechanism of the phenomenon, which has been successfully explained in terms of a spin-dependent quantum confinement effect. The theoretical predictions are discussed in connection with corresponding experimental investigations.Comment: 18 pages, 4 PS figures, LaTeX with IOP package; v2: ref. added.

The Flemish movement and Flemish nationalism: instruments, historiography and debates

This article gives a concise overview of the historiography of the Flemish movement and the Belgian nationality conflict. It addresses the main working instruments and scientific infrastructure. Furthermore it provides an overview of the basic works and the most significant literature in English, French and German. It detects the theoretical frameworks and gives a brief overview of the smouldering historiographical debates: the social players of the Flemish movement in the 19th century; the impact of World War I on Flemish nation building; the Flemish movement during the interwar years and World War II; the ideological developments of the Flemish movement and the Belgian state reform after World War II

General method for prediction of thermal conductivity for well-characterized hydrocarbon mixtures and fuels up to extreme conditions using entropy scaling

A general and efficient technique is developed to predict the thermal conductivity of well-characterized hydrocarbon mixtures, rocket propellant (RP) fuels, and jet fuels up to high temperatures and high pressures (HTHP). The technique is based upon entropy scaling using the group contribution method coupled with the Perturbed-Chain Statistical Associating Fluid Theory (PC-SAFT) equation of state. The mixture number averaged molecular weight and hydrogen to carbon ratio are used to define a single pseudo-component to represent the compounds in a well-characterized hydrocarbon mixture or fuel. With these two input parameters, thermal conductivity predictions are less accurate when the mixture contains significant amounts of iso-alkanes, but the predictions improve when a single thermal conductivity data point at a reference condition is used to fit one model parameter. For eleven binary mixtures and three ternary mixtures at conditions from 288 to 360 K and up to 4,500 bar, thermal conductivities are predicted with mean absolute percent deviations (MAPDs) of 16.0 and 3.0% using the two-parameter and three-parameter models, respectively. Thermal conductivities are predicted for three RP fuels and three jet fuels at conditions from 293 to 598 K and up to 700 bar with MAPDs of 14.3 and 2.0% using the two-parameter and three-parameter models, respectively

Atomic secrets and governmental lies : nuclear science, politics and security in the Pontecorvo case

This paper focuses on the defection of nuclear physicist Bruno Pontecorvo from Britain to the USSR in 1950 in an attempt to understand how government and intelligence services assess threats deriving from the unwanted spread of secret scientific information. It questions whether contingent agendas play a role in these assessments, as new evidence suggests that this is exactly what happened in the Pontecorvo case. British diplomatic personnel involved in negotiations with their US counterparts considered playing down the case. Meanwhile, the press decided to play it up, claiming that Pontecorvo was an atom spy. Finally, the British secret services had evidence showing that this was a fabrication, but they did not disclose it. If all these manipulations served various purposes, then they certainly were not aimed at assessing if there was a threat and what this threat really was

Putting a Spin on Circulating Reference, or How to Rediscover the Scientific Subject

Bruno Latour claims to have shown that a Kantian model of knowledge, which he describes as seeking to unite a disembodied transcendental subject with an inaccessible thing-in-itself, is dramatically falsified by empirical studies of science in action. Instead, Latour puts central emphasis on scientific practice, and replaces this Kantian model with a model of “circulating reference.” Unfortunately, Latour's alternative schematic leaves out the scientific subject. I repair this oversight through a simple mechanical procedure. By putting a slight spin on Latour's diagrammatic representation of his theory, I discover a new space for a post-Kantian scientific subject, a subject brilliantly described by Ludwik Fleck. The neglected subjectivities and ceaseless practices of science are thus re-united

Stability of the Einstein-Lichnerowicz constraints system

We study the Einstein-Lichnerowicz constraints system, obtained through the conformal method when addressing the initial data problem for the Einstein equations in a scalar field theory. We prove that this system is stable with respect to the physics data when posed on the standard $3$-sphere.Comment: Minor changes, some typos fixed and references adde
