考完纯数，老师放了个电影叫美丽心灵，不管是情节或是演员，都非常棒。


其中有一段对话——
Nash：   Alicia, does our relationship warrant long-term commitment?Cause I   need   some kind of proof, some kind of verifiable、empirical    data.
      Alicia： I'm sorry, just give me a moment... to redefine my girlish   notions of romance. A proof? Verifiable data. Um... okay. Well, how   big is the universe?
      Nash：   Infinite.
      Alicia： How do you know?
      Nash：   I know because all the data indicate it.
      Alicia： But it hasn't been proven yet?                               
      Nash：   No.
      Alicia： You haven't seen it. How do you know for sure?
      Nash：   I don't, I just believe it.
      Alicia： Mmm. It's the same with love, I guess. Now, the part that you don't know... is if   I want to marry you.
因为我们只是相信，只是相信。
