To explain the operation of this device Imust remind the reader that modern researchhas shown that the atoms of which materialsubstance are composed are themselves formedof still smaller atoms of electricity called elec-trons. An atom of matter is a very small 250,000,000 atoms of copper or gold wereput in a row, like marbles, touching eachother the row would only be an inch an electron is still smaller.
