这就是光(在这个例子中是从左上部过来的)打到边缘上的地方。
This is where the light (which in this example we're going to have coming from the top left) hits the edge.
根据多普勒效应，光被离子反射后，靠近激光器的光的频率会高于远离激光器的光的频率，（日常生活中，救护车警报器的音调随着车的远近也变化，就是这个道理）这才有可能测量先前对离子施加的力的大小。
(An everyday example of this effect is the change of pitch of an ambulance siren as it approaches and recedes.) It was thus possible to measure the force applied to the ions.
人眼感受的光用流明时这个单位来衡量——燃烧一根蜡烛一个小时所产生的光的量就是一流明时。
The light perceived by the human eye is measured in units called lumen-hours. This is about the amount produced by burning a candle for an hour.
上帝像光一样，但他不是光本身。apophatic语言方式是陈述上帝不是什么，所以像“永恒”这样的词语意味着非时空的、无限的，或者没有限制的，在这个意义上“永恒”就是对我们时空观的否定。
The apophatic language states what God is not, so such terms as "eternal, " which means nontemporal, infinite, or without limitation, are in this sense negative.

你们都在倾泻光，也就是数据和信息，到这个星球上，随着你这么做，你为意识创造了新的通道来没有顾虑地探索。
You are all pulling light, which is data and information, onto the planet, and as you do this you create new pathways for consciousness to explore without even saving a word.
最后，就是“光”这个字了。
好了，现在看清楚了：在这个地球切面上，我们深入地心的这把光剑和赤道线的夹角就是我们的纬度啊！
Now it becomes clearer: on this plane, the angle between the light from the light saber and the Equator is our latitude!
一部似乎并不怎么样的作品居然被时间和空间首肯，这本身就是一个极有文化深度的悬念，光凭着这个悬念也值得去读一读。
A book seemingly not so good actually got approved by time and space, which is a concern of cultural depth itself and is worthy of reading in this particular regard.
