Young André-Marie Ampère was there to witness the death of his father by guillotine, as the head fell from the body to which it belonged. Lifted from the basket, the father's eyes met his son's, sleepily, but blinking once or twice before awareness faded. Was he disgusted by this display? Was he moved by his father, the invisible ink between father and son, as well as mind and body, momentarily, still there? I think he was moved: Ampère showed that parallel wires attract, providing their currents matched. There is no place in the universe, as far as we know, that his math does not apply. It comforts me, so I parallel my spoon to the right of my knife, as is the rule, the knife facing toward the bowl.
