"The past is a foreign country; they do things differently there."
过去是一个异国他乡；他们在那里行事不同。
The universe would look to a two-dimensional creature who spend its life moving on the service of what turned out to be a globe， it could travel for millions of years and would always return to its starting point， it would never be conscious of what was above it or beneath it.
世界是一面镜子，反映出我们带给它的东西。
