That's usually not how it works though. You're more likely to be laughed out of the room for asking such a silly question, despite the fact the (presumably technical) interviewer could do no better without the teacher's copy in front of them.

An aside, but I think interviews like this should allow Internet connections. Give the candidate a minute to look something up and digest it in their own way. It should be obvious whether they'll get the concept or just recite the Wikipedia definition. Just as important is how they do their research, and how they draw connections between foreign and familiar concepts given a blueprint of the former.
