The beauty of topological insulators lies in their robustness; their surface states are protected by symmetry and topology, making them immune to certain types of disorder.
拓扑绝缘体的美在于它们的鲁棒性；它们的表面态受到对称性和拓扑的保护，使它们对某些类型的无序免疫。
"Silence between people can be louder than words."
译文：对国家的法律明知故犯，又怎么能侥幸逃脱法律的制裁；平白无故地侵吞别人的钱财，赔偿要比得到的增加很多倍。赏析：我们在社会上立足，要想走得长远，就要知法守法，不要知法犯法。法律是铁，谁碰谁出血；法律是钢，谁碰谁受伤。喜欢占别人便宜，都是自私自利之人，他们的行为自然招人讨厌，其结果就是因小失大。
I love going one-on-one with someone. That's what I do. I've never lost.
