Free Fall in Gravitational Theory
Wolfgang Engelhardt
Einstein's explanation of Mercury's perihelion motion has been verified by astronomical observations. His formula could also be obtained in Schwarzschild metric and was published a…
Einstein's Third Postulate
Wolfgang Engelhardt
Einstein's own demonstration of time dilation taken from his book with L. Infeld (1938) is analyzed. His ingenious circumnavigation of an apparent discrepancy between clock synchro…
Classical and Relativistic Derivation of the Sagnac Effect
Wolfgang Engelhardt
Both the classical and the relativistic composition law for velocities are applied to re-calculate the Sagnac Effect. The ensuing formulae for the fringe shift are found to differ…
On the Origin of the Lorentz Transformation
Wolfgang Engelhardt
The Lorentz Transformation, which is considered as constitutive for the Special Relativity Theory, was invented by Voigt in 1887, adopted by Lorentz in 1904, and baptized by Poinca…
On the Solvability of Maxwell's Equations
Wolfgang Engelhardt
Complementing a study which was published in this journal in 2005, we present explicit calculations of fields predicted by Maxwell's equations both in Lorenz and in Coulomb gauge.…
Potential Theory in Classical Electrodynamics
Wolfgang Engelhardt
In Maxwell's classical theory of electrodynamics the fields are frequently expressed by potentials in order to facilitate the solution of the first order system of equations. This…
