场景二:Penny谈前男友
-Penny: You want to know the most pathetic part?
Even though I hate his lying, cheating guts...I still love him. Is that crazy?
-Sheldon: Yes.
-Leonard: No, it's not crazy. It's uh... uh... it's a paradox. The paradoxes are part of nature. Think about light. If you look at Huygens, light is a wave, as confirmed by the double-slit experiment, but then along comes Albert Einstein and discovers that light behaves like particles, too.
在对话中,Penny提及前男友这种生物,泪水涟涟。Lenard用光的波粒二象性来安慰失恋的Penny。
(笔者碎碎念:在你伤心的时候,身边有个愿意听你倾诉,用科学理论安慰你的朋友,你就嫁了吧。)
