"A startling development in the last century has been the overflowing of theoretical and observational sciences into the fields of philosophy, particularly by quantum mechanics and cosmology. The present book is twice valuable on this fascinating subject in my opinion: on one hand for its clear and lucid exposition and application of Whitehead's ontology as a most attractive framework for this kind of query, and on the other hand, for its extension of the dialectics of ontology through an original use of advanced concepts from modern mathematics."ROLAND OMNÈS

"This is a unique book in its scope, approach and method. A novel physical and philosophical interpretation of sheaf theory sheds new light on the quantum measurement problem, entanglement, locality and truth. A new systematic and rigorous relational realistic paradigm for natural philosophy has emerged, rooted on the same principles with Abstract (Modern) Differential Geometry, that transmutes the above into a fully fledged dynamical theory."ANASTASIOS MALLIOS

“Recommended reading for graduate students and researchers/faculty. One of the driving contentions in modern physics has been the inability to reconcile the dominance of classical thought in the theory of relativity with the indeterminate nature of quantum mechanics. Some would argue that one such attempt at a compromise had arrived in the form of quantum field theories, with multiple ideas for resolving the asymmetrical features between relativity and ordinary quantum mechanics. Here, Epperson and Zafiris decide to return to ordinary quantum mechanics and propose sheaf theory, a theory that grew out of the abstract algebra of topology and set theory, as a solution to the stubborn paradoxes found in quantization attempts. They then compare the theory's interpretive value to the category scheme found in Whitehead's Process and Reality (1929). Epperson's earlier work, Quantum Mechanics and the Philosophy of Alfred North Whitehead (2004), is a good predecessor to the current book.” CHOICE

"[Foundations of Relational Realism] contributes to a body of literature which seeks to apply sheaf theory (and in many cases, topos theory in particular) to the discussion of quantum non-locality. Particularly noteworthy are the research programs initiated by Butterfield and Isham, Doering and Isham, and Landsman et al., respectively, which seek (modulo subtle differences) to develop a sheaf-theoretic account of quantum mechanics, as well as recent work by Abramsky et al. which brings various types of quantum nonlocality and contextuality under a sheaf-theoretic rubric (but without absorbing the entire structure of quantum mechanics)."
From the Inside Flap
Among the many exotic interpretations of quantum theory--those entailing 'multiverse' cosmologies, 'time reversal,' 'retro-causality,' physical superpositions of alternative actual system states--lies a single core principle: That quantum theory's most emblematic feature is its invalidation of classical logic--the very foundation of intuitive, critical reasoning--at the level of fundamental physics. As a result, quantum mechanics has become widely popularized, and in many cases, marketed, as mystifying and essentially incomprehensible to non-specialists.
Yet at the heart of this popularization lies a paradox: The rules of classical logic purportedly invalidated by quantum mechanics are, at the same time, necessarily presupposed by quantum mechanics; indeed, they are the very rules used to formalize quantum mechanics in the first place. In their groundbreaking new book, Michael Epperson and Elias Zafiris provide a powerful new solution to this paradox by upgrading quantum theory's presupposed set theoretic, metrical structure, grounded in object elements, to a more refined category theoretic, topological structure grounded in object relations. To this end, the book presents a novel, intuitive interpretation of quantum mechanics, based on a revised decoherent histories interpretation, structured within a category theoretic topological formalism.
