The following year, one of Edison's engineers discovered electrons, which eventually led to electronics, the branch of science dealing with electricity. This discovery was patented as the "Edison effect". Without electronics, we might not have radio, TV, computers, or space travel. The rest of Edison's life was spent making and improving inventions including the motion picture camera, the alkaline battery, the copy machine, and the microphone.
第二年，爱迪生手下的一名工程师发现了电子，最后导致电子学的产生。这个发现以“爱迪生效应”获得发明专利。假若没有电子学，我们可能就没有收音机、电视机、电脑，甚至太空旅行。在最后的岁月里，爱迪生继续创造并改进那些发明，其中包括电影摄像机、碱性电池、复印机，以及麦克风。
