Law without law: from observer states to physics via algorithmic information theory [PDF]
Quantum, 2020 According to our current conception of physics, any valid physical theory is supposed to describe the objective evolution of a unique external world. However, this condition is challenged by quantum theory, which suggests that physical systems should not

If Physics Is an Information Science, What Is an Observer? [PDF]
Information, 2012 Interpretations of quantum theory have traditionally assumed a “Galilean” observer, a bare “point of view” implemented physically by a quantum system.

The gravitational path integral from an observer’s point of view [PDF]
Journal of High Energy PhysicsOne of the fundamental problems in quantum gravity is to describe the experience of a gravitating observer in generic spacetimes. In this paper, we develop a framework for describing non-perturbative physics relative to an observer using the ...

How Information Creates Its Observer: Emergence of the Information Observer with Regularities
Proceedings, 2022 Vladimir Lerner’s Information Macrodynamic (IMD) formalism is the first full application of John Archibald Wheeler’s “It from Bit” approach to physical Information processes.

Education Sciences, 2023 This study deals with the concept of the observer in science education, which is currently significantly diminished at school. In the first part, we review the theoretical perspective of the concept, regarding its historical role in physics knowledge ...

Observer effect modulates classification in a quantum epistemic framework [PDF]
Scientific ReportsThe observer effect in quantum physics states that observation inevitably influences the system being observed. This work introduces an epistemic framework that treats the observer as an integral part of sensory information processing within entangled ...

Observer study-based evaluation of a stochastic and physics-based method to generate oncological PET images [PDF]
Medical Imaging, 2021 Objective evaluation of new and improved methods for PET imaging requires access to images with ground truth, as can be obtained through simulation studies.

Covariant cosmography: the observer-dependence of the Hubble parameter [PDF]
Journal of Cosmology and Astroparticle Physics, 2023 The disagreement between low- and high-redshift measurements of the Hubble parameter is emerging as a serious challenge to the standard model of cosmology. We develop a covariant cosmographic analysis of the Hubble parameter in a general spacetime, which

The Measurement Problem Is a Feature, Not a Bug–Schematising the Observer and the Concept of an Open System on an Informational, or (Neo-)Bohrian, Approach [PDF]
Entropy, 2023 I flesh out the sense in which the informational approach to interpreting quantum mechanics, as defended by Pitowsky and Bub and lately by a number of other authors, is (neo-)Bohrian.

Distributed Anomaly Detection and Estimation over Sensor Networks: Observational-Equivalence and $Q$-Redundant Observer Design [PDF]
European Control Conference, 2022 In this paper, we study stateless and stateful physics-based anomaly detection scenarios via distributed estimation over sensor networks. In the stateful case, the detector keeps track of the sensor residuals (i.e., the difference of estimated and true ...
