  1. Losing Sight of the Forest for the Ψ: Beyond the Wavefunction Hegemony.Alisa Bokulich - 2019 - In Steven French & Juha Saatsi (eds.), Scientific Realism and the Quantum. Oxford University Press.
    Traditionally Ψ is used to stand in for both the mathematical wavefunction (the representation) and the quantum state (the thing in the world). This elision has been elevated to a metaphysical thesis by advocates of the view known as wavefunction realism. My aim in this paper is to challenge the hegemony of the wavefunction by calling attention to a little-known formulation of quantum theory that does not make use of the wavefunction in representing the quantum state. This approach, called Lagrangian (...)

  2. Physically Similar Systems: A History of the Concept.Susan G. Sterrett - 2017 - In Lorenzo Magnani & Tommaso Wayne Bertolotti (eds.), Springer Handbook of Model-Based Science. Dordrecht Heidelberg London New York: Springer. pp. 377-412.
    The concept of similar systems arose in physics, and appears to have originated with Newton in the seventeenth century. This chapter provides a critical history of the concept of physically similar systems, the twentieth century concept into which it developed. The concept was used in the nineteenth century in various fields of engineering, theoretical physics and theoretical and experimental hydrodynamics. In 1914, it was articulated in terms of ideas developed in the eighteenth century and used in nineteenth century mathematics (...)

  3. Maxwell, Helmholtz, and the Unreasonable Effectiveness of the Method of Physical Analogy.Alisa Bokulich - 2015 - Studies in History and Philosophy of Science Part A 50:28-37.
    The fact that the same equations or mathematical models reappear in the descriptions of what are otherwise disparate physical systems can be seen as yet another manifestation of Wigner's “unreasonable effectiveness of mathematics.” James Clerk Maxwell famously exploited such formal similarities in what he called the “method of physical analogy.” Both Maxwell and Hermann von Helmholtz appealed to the physical analogies between electromagnetism and hydrodynamics in their development of these theories. I argue that a closer historical examination of the (...)

  4. Maxwellian Scientific Revolution: Reconciliation of Research Programmes of Young-Fresnel,Ampere-Weber and Faraday.Rinat M. Nugayev (ed.) - 2013 - Kazan University Press.
    Maxwellian electrodynamics genesis is considered in the light of the author’s theory change model previously tried on the Copernican and the Einstein revolutions. It is shown that in the case considered a genuine new theory is constructed as a result of the old pre-maxwellian programmes reconciliation: the electrodynamics of Ampere-Weber, the wave theory of Fresnel and Young and Faraday’s programme. The “neutral language” constructed for the comparison of the consequences of the theories from these programmes consisted in the language of (...)

  5. About Appearance of the Irreversibility.Igor V. Lebed - 2014 - Open Journal of Fluid Dynamics 4 (3):298-320.
    The inevitability of arising in equations of kinetics and hydrodynamics irreversibility not contained in original equations of classic mechanics is substantiated. It is established that transfer of information about the direction of system evolution from initial conditions to resulting equations is the consequence of losing information about the position of an individual particle in space, which takes place at roughening description. It is shown that the roughening with respect to impact parameters of colliding particles is responsible for appearance of (...)
