75年前电视在旧金山郊外的一间实验室里诞生了。它的创造者是年仅21岁的美国男孩菲洛·法恩斯沃思。在20世纪的大部分时间里，他几乎被人们遗忘了———尽管他的发明塑造了20世纪，甚至从某种意义上成为这个世纪的特征。

One night, Philo read a magazine story about the idea of sending pictures and sound through the air. Anyone with a device that could receive this electronic information could watch the pictures. The magazine story said some of the world's best scientists were working on the idea. It said these scientists were using special machines to try to make a kind of device to send pictures. The story made Philo think. 14-year-old Philo decided these famous scientists were wrong. He decided that mechanical devices would never work. They could never be made to move fast enough to clearly capture and reproduce an electronic picture sent through the air. Philo decided that such a device would have to be electronic, not mechanical. Philo knew electrons could be made to move extremely fast. All he would have to do was find a way to make electrons do the work. Very quickly Philo had an idea for such a receiver. It would trap light in a container and send the light on a line of electrons. Philo called it "light in a bottle."
