Abstract
The crucial problem of physics was first formulated by Democritus in t he 5th century BC: to find the ''alphatauomualpha'' or smallest uncutt able bits of matter. That has not changed ever since. Among the curren t candidates are electron and positron, the least expensive of today's bona fide alphatuaomualpha. Experimental tests of their non-composite ness by precisely measuring the gyromagnetic ratios of the individual trapped particles are reviewed.
