Robert A. Millikan密立根
Robert A. Millikan (1868-1953) received the 1923 Nobel Prize for his work in determining the charge of the electron and for work confirming Einstein's photoelectric equation. In 1909 he performed the famous "Millikan oil drop experiment" in which was able to suspend tiny droplets of oil in an electric field and therefore measure their charge accurately. The charges were found to be multiples of a number he determined to be 1.64 x 10-19 Coulombs, a number which compares favorably with the currently accepted value of 1.602 x 10-19 C for the charge of an electron. 罗伯特·A·密立根（1868-1953）因确定电子电荷以及确认爱因斯坦光电方程的工作而获得1923年诺贝尔奖。1909年，他进行了著名的“密立根油滴实验”，在实验中他能够将微小的油滴悬浮在电场中，从而准确测量其电荷。测得的电荷值被发现是某个数的倍数，他确定该数为1.64×10⁻¹⁹库仑，这个数值与目前接受的电子电荷值1.602×10⁻¹⁹库仑相比相当。
