En una entrevista con Charles Weiner en 1973, Richard Feynman contó que -para él- el papel no es un registro de lo pensado, sino el trabajo de pensar en si mismo:
Weiner: (Referring to Feynman’s journals) And so this represents the record of the day-to-day work.
Feynman: I actually did the work on the paper.
Weiner: That s right. It wasn’t a record of what you had done but it is the work.
Feynman: It’s the doing it — it’s the scrap paper.
Weiner: Well, the work was done in your head but the record of it is still here.
Feynman: No, it’s not a record, not really, it’s working. You have to work on paper and this is the paper. OK?
