Law without law: from observer states to physics via algorithmic information theory [PDF]

open access: yesQuantum, 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

Disentangling Brillouin’s Negentropy Law of Information and Landauer’s Law on Data Erasure [PDF]

open access: yesEntropy
The 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

open access: yesProceedings, 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.

Threat of arsenic contamination, salinity and water pollution in agricultural practices of Sundarban Delta, India, and mitigation strategies

open access: yesSN Applied Sciences, 2021
The paper through a critical appraisal of the agricultural practices in the Indian Sundarban deltaic region explores the tripartite problems of arsenic biomagnification, salinity of arable lands and ingress of agrochemical pollutants into the freshwater ...

Neural Network-Based Intuitive Physics for Non-Inertial Reference Frames

open access: yesIEEE 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

open access: yesNature 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

open access: yesSensors, 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

Sensitivity of the Action Observation Network to Physical and Observational Learning [PDF]

open access: yesCerebral Cortex, 2008
Human motor skills can be acquired by observation without the benefit of immediate physical practice. The current study tested if physical rehearsal and observational learning share common neural substrates within an action observation network (AON) including premotor and inferior parietal regions, that is, areas activated both for execution and ...

Dynamics and Control of a Magnetic Transducer Array Using Multi-Physics Models and Artificial Neural Networks

open access: yesSensors, 2021
A linear mechanical oscillator is non-linearly coupled with an electromagnet and its driving circuit through a magnetic field. The resulting non-linear dynamics are investigated using magnetic circuit approximations without major loss of accuracy and in ...

Information-Based Physics: An Observer-Centric Foundation [PDF]

open access: yes, 2013
It is generally believed that physical laws, reflecting an inherent order in the universe, are ordained by nature. However, in modern physics the observer plays a central role raising questions about how an observer-centric physics can result in laws ...
