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.

Observers, observations and referencing in physics theories
Journal of Physics: Conference Series, 2021 Abstract Is it possible to encompass the full extent of the universe within a theory based on a finite set of first principles and inference rules? The r^ole of observers and observations in physics theories is considered here in the light of G¨odel’s incompleteness theorem.

Disentangling Brillouin’s Negentropy Law of Information and Landauer’s Law on Data Erasure [PDF]
EntropyThe link between information and energy introduces the observer and their knowledge into the understanding of a fundamental quantity in physics. Two approaches compete to account for this link—Brillouin’s negentropy law of information and Landauer’s law ...

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.

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

Neural Network-Based Intuitive Physics for Non-Inertial Reference Frames
IEEE Access, 2021 Classical mechanics offers us reliable means to predict various physical quantities, but it is difficult to derive the precise dynamic equations underlying most phenomena and obtain physical quantities in real-world situations.

Mixing indistinguishable systems leads to a quantum Gibbs paradox
Nature Communications, 2021 The Gibbs paradox stems from the entropy change upon mixing two gases. Here, by considering bosonic and fermionic statistics, the authors show that an observer unable to distinguish the particles’ spins assigns a greater entropy increase to the mixing ...

Scale Factor Estimation for Quadrotor Monocular-Vision Positioning Algorithms
Sensors, 2022 Unmanned aerial vehicle (UAV) autonomous navigation requires access to translational and rotational positions and velocities. Since there is no single sensor to measure all UAV states, it is necessary to fuse information from multiple sensors. This paper
