The beauty of physics lies not just in the answers it provides, but in the mysteries it reveals.
No arts; no letters; no society; and which is worst of all, continual fear, and danger of violent death; and the life of man, solitary, poor, nasty, brutish, and short.
死者离我们并不远。他们在我们的心中和思想中，最终，他们是我们所拥有的一切。
