The uncertainty principle is not a limitation of our measurement techniques, but a fundamental property of nature.
不确定性原理不是我们测量技术的限制，而是自然界的基本属性。
Your time is limited, so don’t waste it living someone else’s life.
I'm drawn to a lovely quote by St. Augustine in "The City of God," where he says, "It's a sin to judge any man by his post." In modern English that would mean it's a sinto come to any view of who you should talk to, dependent on their business card. It's not the post that should count. According to St. Augustine, only God can really put everybody in their place; he's going to do that on the Day of Judgment, with angels and trumpets, and the skies will open. Insane idea, if you're a secularist person, like me. But something very valuable in that idea, nevertheless.
Curiosity drives the mathematician forward, always seeking the next question to answer.
