Two Kinds of Electron?
Miller, Franklin, Jr.
Physics Teacher, v45 n4 p210-216 Apr 2007
In the 1930s physicists were confronted by two conflicting values for the charge of the electron as measured with great precision by two different methods. Could it be that there are two kinds of (negative) electrons, differing in charge by a fraction of a percent? The experiments were reconciled when a small systematic error in one of the experiments was identified and taken into account using elementary methods. This is physics at its best.
