Technical terms?

[Stephen]

I just started listening to this after listening to it two years ago. At one point, the hyper-geeky physics nerd Andy is babbling about why Law can't possibly be interested in him. Oddly, he uses the phrase "one ten billionth of a meter". I'm no physics maven myself, but it struck me that the term for that is an ångström. It's a minor point, but if an author is going to use physics tutoring as a background, they should do a bit of familiarization first.
