? Gold atoms seem to act like bits of paper when they are brought near
an electrostatically charged plastic rod. Maybe it's esoteric science?
The mystery is why "Eimac's Reid Brandon told QST's Technical Topics
Editor (Paul Pagel) that Eimac's Chief Specifications Engineer (W. Foote)
was not authorized to tell yours truly about the gold-sputtering
phenomenon?
