The exact radiation-reaction equation for a classical charged particle
An unsolved problem of classical mechanics and classical electrodynamics is the search of the exact relativistic equations of motion for a classical charged point-particle subject to the force…

Dielectric Screening in a Spherical Cavity
In this work we examine the electrostatic screening potential due to a point charge located off-centre in a spherical dielectric cavity. This potential is expanded for the case in which the…

Electromagnetic energy-momentum equation without tensors: a geometric algebra approach
In this paper, we define energy-momentum density as a product of the complex vector electromagnetic field and its complex conjugate. We derive an equation for the spacetime derivative of the…

The Lorentz Force and the Radiation Pressure of Light
In order to make plausible the idea that light exerts a pressure on matter, some introductory physics texts consider the force exerted by an electromagnetic wave on an electron. The argument as…

Two Permanently Congruent Rods May Have Different Proper Lengths
We scrutinize congruence as one of the basic definitions of equality in geometry and pit it against physics of Special Relativity. We show that two non-rigid rods permanently kept congruent during…

Dynamical constants for electromagnetic fields with elliptic-cylindrical symmetry
Taking into account the characteristics of a free scalar field in elliptic coordinates, a new dynamical variable is found for the free electromagnetic field. The conservation law associated to this…

Observation of negative impulse velocity in free space
Since the 1983 definition of the speed of light in vacuum as a fundamental constant with the exact value of 299792458 m/s the question remains as to what apart from the wavefront travels at that…

On the validity of the LAD and LL classical radiation-reaction equations
The search of the correct equation of motion for a classical charged particle under the action of its electromagnetic (EM) self-field, the so-called radiation-reaction equation of motion,…

The Sivashinsky equation for corrugated flames in the large-wrinkle limit
Sivashinsky's (1977) nonlinear integro-differential equation for the shape of corrugated 1-dimensional flames is ultimately reducible to a 2N-body problem, involving the 2N complex poles of the…

Propagation of compressional elastic waves through a 1-D medium with contact nonlinearities
Propagation of monochromatic elastic waves across cracks is investigated in 1D, both theoretically and numerically. Cracks are modeled by nonlinear jump conditions. The mean dilatation of a single…

The Theory of Relativity - Galileo's Child
We determine the Lorentz transformations and the kinematic content and dynamical framework of special relativity as purely an extension of Galileo's thoughts. No reference to light is ever…

A two-fluid model for violent aerated flows
In the study of ocean wave impact on structures, one often uses Froude scaling since the dominant force is gravity. However the presence of trapped or entrained air in the water can significantly…

Prediction of residual stress due to early age behaviour of massive concrete structures: on site experiments and macroscopic modelling
Early age behaviour of concrete is based on complex multi-physical and multiscale phenomena. The predication of both cracking risk and residual stresses in hardened concrete structures is still a…

Hamiltonian Principle in Binary Mixtures of Euler Fluids with Applications to the Second Sound Phenomena
