To the Problem of Discontinuous Solutions in Applied Mathematics
Mathematics, 2023 This paper addresses discontinuities in the solutions of mathematical physics that describe actual processes and are not observed in experiments. The appearance of discontinuities is associated in this paper with the classical differential calculus based

Twilight for the energy conditions? [PDF]
, 2002 The tension, if not outright inconsistency, between quantum physics and general relativity is one of the great problems facing physics at the turn of the millennium.

Entropy Considerations in Stochastic Electrodynamics
PhysicsThe use of entropy concepts in the field of stochastic electrodynamics is briefly reviewed here. Entropy calculations that have been fully carried out to date are discussed in two main cases: first, where electric dipole oscillators interact with zero ...

Simple universal models capture all classical spin physics [PDF]
, 2016 Spin models are used in many studies of complex systems---be it condensed matter physics, neural networks, or economics---as they exhibit rich macroscopic behaviour despite their microscopic simplicity.

Thermodynamic Operations and Entropy Considerations for a Ring-of-Charge Oscillator System
EntropyA ring of classical charge with a charged point particle oscillating within is first analyzed. The charged particle interacts with classical electromagnetic thermal radiation, which causes the particle to fluctuate, while the ring of charge imparts a ...

REVISITING PHILOSOPHICAL FOUNDATIONS OFUNCERTAINTY IN CLASSICAL PHYSICS
Дискурс, 2019 The article addresses the problem of uncertainty in classical thermodynamics and mechanics. The relation of concepts of certainty and uncertainty is studied in detail, and they are considered opposites forming the basis of any system.

An Introduction to Noncommutative Physics
Physics, 2023 Noncommutativity in physics has a long history, tracing back to classical mechanics. In recent years, many new developments in theoretical physics, and in practical applications rely on different techniques of noncommutative algebras.

Splits in students’ beliefs about learning classical and quantum physics
International Journal of STEM Education, 2019 Background While there has been increasing recognition of the importance of attending to students’ views about what counts as knowing and learning a STEM field, surveys that measure these “epistemological” beliefs are often used in ways that implicitly ...

Quantum finite difference solvers for physics simulation
IET Quantum Communication, 2023 Physics systems are becoming increasingly complex and require more and more computing time. Quantum computing, which has shown its efficiency on some problems, such as the factorisation of a number with Shor's algorithm, may be the solution to reduce ...

Rethinking ‘Classical Physics’ [PDF]
, 2017 This article discusses the reasons for rethinking ‘classical physics’, building upon Richard Staley’s historical enquiry into the origins of the distinction between ‘classical’ and ‘modern physics’. In particular, it challenges Staley’s thesis that ‘classical’ and ‘modern physics’ were invented simultaneously by Max Planck at the Solvay conference in ...
