Without a line of software, how does a machine know the next step? →Follow a pulse of water in a coffee maker and five scoring pulses in a pinball machine. Valves, cams and magnetic latches each leave an observable moment when the next step becomes possible.Why does moving the measurement change the verdict on a machine? →Open a dishwasher after its first drain, then remove the bread from a toaster. Two small experiments expose where a measurement begins, where it ends and what the instrument actually senses.Who wins when the same voters are counted differently? →Start with one fictional voter’s second choice, then follow districts, seats and national totals. At each stage mark which information survives and which questions the result can still answer.
