The Love Lottery (1954)
Rex Allerton: What do you do?
Jane Dubois: I am a mathematician.
Rex Allerton: Teehee, you're what?
Jane Dubois: I see what you mean. It's improbable, isn't it?
Rex Allerton: No, I'm sorry. No, I didn't mean to...
Jane Dubois: No, no. It's quite alright. Hardly anyone believes me at first but when I multiply a few 10 digit numbers and give them the cube root for a few more, they come around.
Rex Allerton: You do all that?
Jane Dubois: And more, Smithy, and more.
Rex Allerton: Look this may be my last night in Tremaggio. Will you have dinner with me?
Jane Dubois: Of course! I've been sitting in this wet suit waiting for you to speak up. Come around at 8:30. We'll do some compound fractions before dinner.
Jane Dubois: Little else remains to be told. While other little girls were rolling hoops or playing games with little boys, I was at home, contentedly finding the hypotenuse of this or that, letting x equal all sort of things. Before you could find the cube root of 9, I was a well-known genius.
