These are the times that try men's souls.
这是考验人们灵魂的时刻。
Mental processes are biological tools for survival.
Model checking is a powerful tool for verifying the correctness of hardware and software systems.
一个人乘火箭飞向星空，而我只有这把破吉他。
人类的痛苦和快乐是相通的，无论我们来自哪里。
"To write is to walk on the edge of the unspeakable."
The world is full of stories, but the stories are all one.
