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，愛(ài)迪生手下的一名工程師發(fā)現(xiàn)了電子，最后導(dǎo)致電子學(xué)的產(chǎn)生。這個(gè)發(fā)現(xiàn)以“愛(ài)迪生效應(yīng)”獲得發(fā)明專利。假若沒(méi)有電子學(xué)，我們可能就沒(méi)有收音機(jī)、電視機(jī)、電腦，甚至太空旅行。在最后的歲月里，愛(ài)迪生繼續(xù)創(chuàng)造并改進(jìn)那些發(fā)明，其中包括電影攝像機(jī)、堿性電池、復(fù)印機(jī)，以及麥克風(fēng)。
