Breaking Up The Indivisible To Observe The Implausible,particles With A Fractional Charge
arstechnica.com 4 weeks, 1 day agoIt was 1909 when Robert Millikan and Harvey Fletcher carried out their famous oil drop experiment in which they determined that the smallest unit of charge possible was 1.592x10 -19 Coulombs, a value we now refer to as e , the fundamental charge (the modern accepted value is 1.602176565(35)x10 -19 C). It is the magnitude of the negative charge carried by the electron, as well as the positive charge of a proton. It is also the smallest unit of charge that any stable, independent particle can possibly have,no
