生活是世界上最罕见的事情。大多数人只是存在，仅此而已。

The truth is rarely pure and never simple.

The beauty of topological insulators lies in their robustness; their surface states are protected against disorder and imperfections.

The best leaders are those who empower others to grow, just like how sunlight nurtures every fruit on the tree.

宁要知识不要财富，因为一个是短暂的，另一个是永恒的。

没有什么比不快乐更有趣了。
