OK. In the length of time it takes for the light to get from that bulb to the table, this machine processes two operations.

好，在灯光从灯泡到,桌子的这段时间内，电脑已经进行了两次运算了。

A gig is 10 to the 9, so it does two operations in the length of time it takes light to get from one foot off the table down to the table. That's amazing.

因此光行进一英尺的,时间内电脑可以,进行两次基本运算,这太神奇了。
