Structural Realism, Metaphysical Unification, and the Ontology and Epistemology of Patterns

Ladyman and Ross's account of the metaphysical component of ontic structural realism was associated with a unificationist view of the connection between fundamental physics and special sciences. The aim of the present article is to assess the sense of unification that is at issue in Ladyman and Ross's definition of metaphysics. Given the ontic core of Ladyman and Ross's version of structural realism, it should be assumed that the unifying endeavour is worthwhile only if the connective links that underpin unification are metaphysically significant. Ladyman and Ross employed information-theoretic notions, e.g. projectibility', to account for the significance of real patterns, which underpin unification. I build upon McAllister's engagements with the same topic, to argue that these notions fail to accomplish this objective.


Material Processuality: Alternative Grounds for Design Research
Tönük Kruıthof, Damla (Informa UK Limited, 2020-01-01)
This article opens discussion on the positivist epistemology underlying the understandings of materials in design research that have been brought along as a result of theory and methods inherited from engineering and psychology. Examining the ambitions of work that seeks to operationalize knowledge created by these methods in the design process, we propose that attending to the processuality of material forms is a more adequate way for design research to capture the multiplicity of materials. We develop thi...
Syntactical Informational Structural Realism
Davoody Benı, Majıd (2018-12-01)
Luciano Floridi's informational structural realism (ISR) takes a constructionist attitude towards the problems of epistemology and metaphysics, but the question of the nature of the semantical component of his view remains vexing. In this paper, I propose to dispense with the semantical component of ISR completely. I outline a Syntactical version of ISR (SISR for short). The unified entropy-based framework of information has been adopted as the groundwork of SISR. To establish its realist component, SISR sh...
Causality in curved space
Aljasem Alashour, Bassem; Tekin, Bayram; Department of Physics (2018)
The notion of Causality is a key concept in formulating theories that describe real physical systems. So when a proposed model violates this concept this usually signals the existence of an error in the conceptual formulation or in the physical understanding of the results, which might indicate to us which models should we pursue, modify or drop all together. In this work the possibility of causality violations introduced by modifying Einstein gravity is studied using the idea of the time-delay introduced t...
Discrete symmetries in quantum theory
Taşdan, İsmail Ufuk; Pak, Namık Kemal; Department of Physics (2015)
In this thesis, one of the most central problems of modern physics, namely the discrete symmetries, is discussed from various perspectives ranging from classical mechanics to relativistic quantum theory. The discrete symmetries, namely charge conjugation (C), parity (P), time reversal (T), which are connected by the so-called CPT Theorem are studied in detail. The anti-particles with a view to matter-anti-matter symmetry is also addressed and the anti-unitarity nature of the time reversal, as well as the CP...
Dual metrics and nongeneric supersymmetries for a class of Siklos space-times
Baleanu, D; Baskal, S (2002-10-20)
The presence of Killing-Yano tensors implies the existence of nongeneric supercharges in spinning point particle theories on curved backgrounds. Dual metrics axe defined through their associated nondegenerate Killing tensors of valence two. Siklos space-times, which are the only nontrivial Einstein spares conformal to nonflat pp-waves are investigated with regard to the existence of their corresponding Killing and Killing-Yano, tensors. It is found that a class of Siklos space-times admit dual metrics and n...
