Contextuality and indistinguishability Vrije Universiteit Brussel
It is well known that in quantum mechanics we cannot always define consistently properties that are context independent. Many approaches exist to describe contextual properties, such as Contextuality by Default (CbD), sheaf theory, topos theory, and non-standard or signed probabilities. In this paper, we propose a treatment of contextual properties that is specific to quantum mechanics, as it relies on the relationship between contextuality ...
On the role of contextuality in the integration of worldviews Vrije Universiteit Brussel
While scientific knowledge has become more and more sophisticated and specialized, it has also become increasingly fragmented. To find new, innovative ideas and lines of research now requires an integrative approach to science. We argue for the view that important progress in this respect is possible if we adopt theoretical insights and mathematical techniques from the field of quantum physics, much like chaos and complexity science has been ...
Non-communicable disease risk associated with red and processed meat consumption-magnitude, certainty, and contextuality of risk? Ghent University Vrije Universiteit Brussel
Probing the Meaning of Quantum Mechanics: Information, Contextuality, Relationalism Vrije Universiteit Brussel
Unscrambling the Omelette of Quantum Contextuality (Part I): Preexistent Properties or Measurement Outcomes? Vrije Universiteit Brussel
In this paper we attempt to analyze the physical and philosophical meaning of quantum contextuality. We will argue that there exists a general confusion within the foundational literature arising from the improper “scrambling” of two different meanings of quantum contextuality. While the first one, introduced by Bohr, is related to an epistemic interpretation of contextuality which stresses the incompatibility (or complementarity) of measurement ...
The Logos Categorical Approach to Quantum Mechanics: I. Kochen-Specker Contextuality and Global Intensive Valuations Vrije Universiteit Brussel
In this paper we present a new categorical approach which attempts to provide an original understanding of QM. Our logos categorical approach attempts to consider the main features of the quantum formalism as the standpoint to develop a conceptual representation that explains what the theory is really talking about —rather than as problems that need to be bypassed in order to allow a restoration of a classical “common sense” understanding of ...
Foreword to Quantum Probability and Contextuality in Psychology and Economics Vrije Universiteit Brussel
Horizonal Extensions of Attention: A Phenomenological Study of the Contextuality and Habituality of Experience KU Leuven
Attention is a complex process that modulates perception in various ways.Phenomenological philosophy provides an array of concepts for describing the rich structures of attention, thereby avoiding reductions to singular aspects of an experiential spectrum. By suggesting various modes and levels of attentional experience, we intend to do some justice to its complexity, taking into account sub-personaland personal factors on the side of subjective ...
The problem of contextuality and the impossibility of experimental metaphysics thereof KU Leuven
Recently a new impulse has been given to the experimental investigation of contextuality. In this paper we show that for a widely used definition of contextuality there can be no decisive experiment on the existence of contextuality. To this end, we give a clear presentation of the hidden variable models due to Meyer, Kent and Clifton (MKC), which would supposedly nullify the Kochen-Specker Theorem. Although we disagree with this last statement, ...
