Among thousands of people, you meet those you've met. Through thousands of years, across the boundless wilderness of time, you happen to meet them, neither earlier nor a bit too late. There is nothing to be said except to ask lightly, "Oh, you're here too?"
于千万人之中遇见你所遇见的人，于千万年之中，时间的无涯的荒野里，没有早一步，也没有晚一步，刚巧赶上了，那也没有别的话可说，惟有轻轻地问一声："噢，你也在这里吗？"
如果你掉进了黑暗里，你能做的，不过是静心等待，直到你的双眼适应黑暗。
科学是一个不断学习和适应的旅程。
勤俭了就有了约束，有约束了就会各种好事都做；奢侈就放肆，放肆则各种坏事都泛滥。
