In this video segment adapted from ZOOM, cast members show you how to make your very own electroscope. You can use it to find out if an object is electrically charged. [4:17]

In this learning module, students will observe interactions between objects, including objects with electric charges to identify patterns in how things interact.

From the ESD Journal website. This page describes the industrial and medical risks associated with the buildup of static charge. The investigation of the electric potential created by such accumulated charges and the materials...

Learn about conductors and electric fields in static equilibrium.

A large complete authoritative biography of Coulomb. Five large pictures, over a dozen links to contemporaries, references, a poster, other mathematicians. A fine source.
