  1. The tool box of science: Tools for the building of models with a superconductivity example.Nancy Cartwright, Towfic Shomar & Mauricio Suárez - 1995 - Poznan Studies in the Philosophy of the Sciences and the Humanities 44:137-149.
    We call for a new philosophical conception of models in physics. Some standard conceptions take models to be useful approximations to theorems, that are the chief means to test theories. Hence the heuristics of model building is dictated by the requirements and practice of theory-testing. In this paper we argue that a theory-driven view of models can not account for common procedures used by scientists to model phenomena. We illustrate this thesis with a case study: the construction of one of (...)

  2. Phenomenologism vs fundamentalism: The case of superconductivity.Towfic Shomar - 2008 - CURRENT SCIENCE, 94 (10):1256-1264.
    This article argues that phenomenological treatment of physical problems is more powerful than fundamental treatment. Developments in the field of superconductivity present us with a clear example of such superiority. The BCS (Bardeen, Cooper and Schrieffer) was accepted as the fundamental theory of superconductivity for a long time. Nevertheless, Landau and Ginzburg phenomenological model has so far proven to be a more fruitful theoretical representation to understand and to predict the features of superconductivity and superconductive materials.

  3. Does the superfluid part of a supersolid, superfluid, or superconducting body have, of itself, “inertia?”.Gary Stephens - 2009 - Annales de la Fondation Louis de Broglie 34 (1):89-101.
    The contention discussed here, is that one might be able to get around the puzzle contained in the results of Kim and Chan:— That a quantity of inertial mass is effectively lost, (a so called non-classical-rotational inertia NCRI,) but that being a “supersolid” there is no path for the normal fraction to slip past the 1 – 2 % supersolid fraction, which (it is supposed) remains stationary within the annulus. As a solution we argue that the effective loss of inertial (...)

  4. What do we mean when using the acronym 'BCS'?Alexander Gabovich & Vladimir Kuznetsov - 2013 - European Journal of Physics 34 (2):371-382.
    The history and use of the acronym ‘BCS’ (named after Bardeen, Cooper and Schrieffer) in the science of superconductivity is traced and analysed. It is shown that a number of different theories are labelled ‘BCS’. The confusion in the application of the term ‘BCS’ is shown to be common because the term ‘theory’ itself is not precisely defined in physics. Recommendations are given to physics readers and students on how to distinguish between various theories referred to as ‘BCS’. Contributions (...)

  5. Entanglement of two Josephson junctions: Current Locking revisited.Gary Stephens - manuscript
    In this essay we take the view that too much reality has been afforded to the notion of ‘particles’ and to ‘flow of supercurrent,’ in the superconducting state. Instead we take the original point of view of Josephson that “ It is clear that intuition is of no great help in understanding the supercurrent as a flow of Cooper pairs “ which is more akin to, and in line with, a “telegraphing of amplitudes” approach. With this conception in mind, we (...)

  6. Mathematical Nature of Gravity, Which General Relativity Says is Space-Time : Topology Unites With the Matrix, E=mc2, Advanced Waves, Wick Rotation, Dark Matter & Higher Dimensions.Rodney Bartlett - manuscript
    General Relativity says gravity is a push caused by space-time's curvature. Combining General Relativity with E=mc2 results in distances being totally deleted from space-time/gravity by future technology, and in expansion or contraction of the universe as a whole being eliminated. The road to these conclusions has branches shining light on supersymmetry and superconductivity. This push of gravitational waves may be directed from intergalactic space towards galaxy centres, helping to hold galaxies together and also creating supermassive black holes. Together with (...)

  7. Ethics after the information revolution.Luciano Floridi - 2010 - In The Cambridge Handbook of Information and Computer Ethics. Cambridge University Press. pp. 3-19.
    This chapter discusses some conceptual undercurrents, which flow beneath the surface of the literature on information and computer ethics (ICE). It focuses on the potential impact of Information and Communication Technologies (ICTs) on our lives. Because of their 'data superconductivity', ICTs are well known for being among the most influential factors that affect the ontological friction in the infosphere. As a full expression of techne, the information society has already posed fundamental ethical problems, whose complexity and global dimensions are (...)

  8. A BRIEF OUTLINE OF THE POSSIBLE BASICS OF COSMOLOGY IN THE 22nd CENTURY, AND WHAT IT MEANS FOR RELIGION.Rodney Bartlett - manuscript
    This article’s conclusion is that the theories of Einstein are generally correct and will still be relevant in the next century (there will be modifications necessary for development of quantum gravity). Those Einsteinian theories are Special Relativity, General Relativity, and the title of a paper he published in 1919 which asked if gravitation plays a role in the composition of elementary particles of matter. This paper was the bridge between General Relativity and the Unified Field Theory he sought during the (...)
