Sur le tableau : deux probl\u00e8mes. Il les recopie, persuad\u00e9 qu\u2019il s\u2019agit d\u2019un devoir. Il travaille, s\u2019acharne, et rend des solutions. Surprise : ces exercices n\u2019\u00e9taient pas un devoir\u2026 mais des probl\u00e8mes ouverts, pr\u00e9sent\u00e9s par le statisticien Jerzy Neyman.

Des sources solides reviennent pourtant au m\u00eame c\u0153ur du r\u00e9cit : un retard, une \u00e9tiquette trompeuse (\u201cdevoir\u201d), et deux probl\u00e8mes r\u00e9ellement non r\u00e9solus au moment o\u00f9 il les copie.
