On the Complexity of Measurement in Classical Physics
2008If we measure the position of a point particle, then we will come about with an interval [an, bn] into which the point falls. We make use of a Gedankenexperiment to find better and better values of an and bn, by reducing their relative distance, in a succession of intervals [a1, b1] ⊃ [a2, b2] ⊃ ... ⊃ [an, bn]] that contain the point.We then use such a

Foundations of classical physics
2007We choose the classical canonical theory of Liouville because of the best match with the q-theory—a genuine statistical theory. Also this is why we devote the particular Sect. 2.4 to the measurement of the physical quantities.

Classical Physics Foundations for Quantum Physics
1997We employ classical principles to justify various quantum concepts. Among these are (1) the Planck formula for the energy of a photon, (2) the de Broglie relation, (3) the Schrodinger energy and momentum operators, (4) the position-momentum commutator relation and (5) the Schrodinger wave function.

Physical Aging of Classical Oscillators
Physical Review Letters, 2014Aging is a familiar phenomenon from glassy systems like spin glasses and materials with slow relaxation processes, breaking of time-translation invariance, and dynamical scaling. We study aging in active rotators and Kuramoto oscillators that are coupled with frustrated bonds.

On the Classical Transcendents of Mathematical Physics
American Journal of Mathematics, 1951(5) x" -q(x)y=0 of (2), cf. [5]. The purpose of this paper is an application of this result to the case of certain classical linear differential equations occurring in mathematical physics. For instance, there will be considered (? 1) the so-called toroidal functions which, in the main, are certain normalizations of the associated Legendre functions ...

Fast Algorithms for Classical Physics
Science, 1994Some of the recently developed fast summation methods that have arisen in scientific computing are described. These methods require an amount of work proportional to N or N log N to evaluate all pairwise interactions in an ensemble of N ...

Concepts of Time in Classical Physics
1997My aim in this review is to describe the three main concepts of time which have been, and still are used in physics, viz. the time concepts of Newtonian physics, of Einstein’s special theory of relativity, and of his general theory of spacetime and gravitation.

Integration of classical and quantum physics
Physical Review A, 1989The perennial aspect of the Newtonian foundation of mathematical physics is that the concept of motion,'' that is, kinematics,'' is to serve as the interface between mathematics and physics. Kinematics subdivides into the theory of orbital translation and that of undulation and spinning.

CLASSICAL AND NONCLASSICAL REPRESENTATIONS IN PHYSICS - PHYSICS-1
Cybernetics and Systems, 1990Dynamical representations used in physics are analyzed from a “second-order” viewpoint, as distinction systems constructed by an observer in interaction with an object. The creation, conservation, and destruction of distinctions can be understood on the basis of a distinction dynamics.
