On non-monochromatic plane-wave solutions of Maxwell's equations
C. J. Papachristou
In electrodynamics courses and textbooks the properties of plane electromagnetic waves in both conducting and non-conducting media are typically studied from the point of view of t…
Revisiting the charging-capacitor problem
C. J. Papachristou
The charging capacitor is used as a standard paradigm for illustrating the concept of the Maxwell "displacement current". A certain aspect of the problem, however, is often overloo…
Does the electromotive force (always) represent work?
C. J. Papachristou, A. N. Magoulas
In the literature of Electromagnetism, the electromotive force of a "circuit" is often defined as work done on a unit charge during a complete tour of the latter around the circuit…
Foundations of Newtonian Dynamics: An Axiomatic Approach for the Thinking Student
C. J. Papachristou
Despite its apparent simplicity, Newtonian Mechanics contains conceptual subtleties that may cause some confusion to the deep-thinking student. These subtleties concern fundamental…
