我脑海里浮现出了一个极秒的想法。
泰洛斯1号卫星在两极之间环绕地球运行，每30秒钟拍摄一张照片，如配图中的图像系列所示。
TIROS-1 orbited from pole to pole, snapping photos every 30 seconds, as illustrated in this series of images.
你拿出手机瞥了两秒，发现并没有谁有急事找你，你就轻松地将你的手机滑落回你的口袋或者钱包里(如果你是个超级极客，那也可能是个手机皮套)。
After a two-second peek, you knew that you were not in desperate demand, and you were free to slip your cell back into your pocket or purse (or cell phone holster, if you were a huge geek).
