不要弄乱我的圆！（据传是罗马士兵入侵时，阿基米德临终前的话）
Happiness is not just the absence of sadness; it's the presence of meaning.
The unknown is not to be feared but to be explored.
The complexity of software is an essential property, not an accidental one.
The most formidable weapon against errors of every kind is reason.
The only thing that stands between a person and what they want in life is the will to try it and the faith to believe it’s possible.
