“They don't understand because they don't have a heart”
“I told you. You don't love someone because of their looks or their clothes or their car. You love them because they sing a song only your heart can understand.”
“You have to do stuff that average people don't understand because those are the only good things.”
“Good, because I don't understand anything at all.”
“I don't understand you. You don't understand me. What else do we have in common?”
“What I am going to tell you about is what we teach our physics students in the third or fourth year of graduate school... It is my task to convince you not to turn away because you don't understand it. You see my physics students don't understand it... That is because I don't understand it. Nobody does.”
