He was also a socialist senator in the Belgian Parliament. Once, as he was at the airport waiting for his plane to the USSR, his students cheered him and chanted "Papy russe, Papy russe" (which sounds exactly like "papyrus" in French). He often signed his articles $\not \pi$, because in French "pas pi" (= "not pi") is homophonic to Papy. | |
