What's the lesson here? To remember your Taylor series? To never exaggerate your mathematical prowess to anti-communist vigilantes? That in Ukraine, even vigilantes know more math than I remember? Or that in Ukraine, even knowing math won't keep you out of a life of vigilantism?
During the Russian revolution, the mathematical physicist Igor Tamm was seized by anti-communist vigilantes at a village near Odessa where he had gone to barter for food. They suspected he was an anti-Ukranian communist agitator and dragged him off to their leader. Asked what he did for a living he said that he was a mathematician.
The sceptical gang-leader began to finger the bullets and grenades slung around his neck. "All right", he said, "calculate the error when the Taylor series approximation of a function is truncated after n terms. Do this and you will go free; fail and you will be shot". Tamm slowly calculated the answer in the dust with his quivering finger. When he had finished the bandit cast his eye over the answer and waved him on his way.
