But who prays for Satan? Who, in eighteencenturies, has had the common humanity to pray for the one sinner that needed it most?(From Jane Lampton Clemens)
Life is an adventure, and every challenge is an opportunity to grow.
Theorems are eternal; their proofs are ephemeral.
永远不要停止学习——世界一直在变化。
科学不仅仅是事实的集合;它是一种思考方式。
What can be said at all can be said clearly; and whereof one cannot speak thereof one must be silent.
