"Theologians talk about a prevenient grace that precedes grace itself and allows us to accept it. I think there must also be a prevenient courage that allows us to be brave - that is, to acknowledge that there is more beauty than our eyes can bear, that precious things have been put into our hands and to do nothing to honor them is to do great harm."

我认为最好的写作来自真实的地方，即使它是痛苦的。

相对论不仅仅是一种科学理论；它是一种哲学理论。

Every material has a memory, and every action leaves a trace.
