宇宙是不对称的，我相信我们所知的生命是宇宙不对称的直接结果或其间接后果。

Stories you read when you're the right age never quite leave you. You may forget who wrote them or what the story was called. Sometimes you'll forget precisely what happened, but if a story touches you it will stay with you, haunting the places in your mind that you rarely ever visit.

"We always overestimate the change that will occur in the next two years and underestimate the change that will occur in the next ten. Don't let yourself be lulled into inaction."

The only fence against the world is a thorough knowledge of it.

The world is full of people who will tell you what you can't do. What you must do is find the ones who will tell you what you can.
