爱迪生是个大发明家,电灯,是他奉献给人类的伟大发明之一.有一次,他想要测定灯泡(还没有制成成品)的容积,把这个问题交给了数学系毕业的助手阿普顿去解决.阿普顿是普林斯顿大学数学系的毕业生.数学水平相当高.他拿着这个灯泡,打量了好半天,找来皮尺,上下左右量了尺寸,开始了紧张的工作.一个多小时过去了,爱迪生着急了,跑来问他算出的结果,汗流浃背的阿普顿慌 Edison, a big inventor and lamp, was one of the great inventions that he dedicated to mankind.Once he wanted to measure the volume of the bulb (which had not yet been finished), and gave it to the graduate Auburn Upton is a graduate of the Department of Mathematics at Princeton University, a very high level of mathematics, he took the light bulb, looked for a long time, to find a tape measure, up and down the amount of size, began a tense work. Hours passed and Edison was in a hurry, came and asked him to calculate the result, sweaty Upton panicked
