我不知道我为什么爱你，但是我爱你。

The beauty of physics lies in its ability to reveal the underlying simplicity of the complex universe.

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.

我不是身体，我是思想。
