And he that sat was to look upon like a jasper and a sardine stone: and there was a rainbow round about the throne, in sight like unto an emerald.

看那坐着的，好像碧玉和红宝石。又有虹围着宝座，好像绿宝石。

When you look into a mirror in the morning to comb your hair, when you see a rainbow after it rains, in medical devices that save lives, as you read this page, as you see, optics is at work.

当你在早晨面对一面镜子梳你的头发时，当你在雨后看到彩虹时，在那些挽救生命的医学设备里，当你读这篇文章时，如你所见，是光在工作。
