This short video captures a memorable moment in a Stanford engineering lecture (ME 352B: Fundamentals of Heat Conduction) when the professor interrupts his introduction to burst into the famous "Largo al factotum" aria from Rossini's The Barber of Seville. The spontaneous operatic performance—complete with the repeated "Figaro" lyrics and Italian exclamations like "bravo bravissimo"—demonstrates how academic teaching can blend discipline with unexpected joy.
