Chapter Four Overview – Electrical Capacitors & Other Tools

We relate to our own culture and time and the tools we possess for certain uses. It doesn’t occur to us that ancient objects could have been used in ways we can’t imagine, especially after thousands of years. Objects that Egyptologists have called “hand mirrors” fit the profile of modern electrical capacitors. They have round metal disks that are non-reflective with removable and interchangeable handles made of bone, wood, or ivory—all non-conductive materials. Because they seem to resemble hand mirrors they were identified as such. A modern version of the same tool, used to capture static electricity, can be purchased today.
