The differential forms research group at BYU is investigating the use of the calculus of differential forms in teaching and research. Differential forms have been used to express Maxwell's laws since early in this century, but many of the advantages of forms as a tool for applied electromagnetics have only recently been discovered.
Explanation of principles and experiments, from How Stuff Works.
Describes Lorentz scalars, covariant and contravariant vectors and tensors, and how to use relativistic notation to describe charge conservation and the inhomogenous wave equation for potentials.
Explanation of how compasses work and how to make your own, from How Stuff Works.
Description of Van de Graaff generators and static electricity, from How Stuff Works.
A brief explanation from How Stuff Works.
Principles of operation of silicon photovoltaic cells.
Surface electromigration refers to the directed motion of atoms (adatoms) at solid surfaces, grain boundaries and interfaces which is caused by an electric current in the bulk of the material. It is considered a key factor determining the reliability of integrated circuits.
The true "left handed" material is described. In this medium, light waves are expected to exhibit a reverse Doppler effect.
