How did Wheel and Cart lead to Information theory?

7 steps · 7 domains · 5,448 years

Wheel and Cart~3,500 BC · 3,500 BCA disc turning on an axle that converts dragging into rolling, cutting the effort of moving a heavy load overland many times over.

Lever, Pulley, Screw, Gear~6,000 BC (levers and ramps) · 6,000 BCThe simple machines — lever, ramp, pulley, screw, gear — that trade force for distance, letting ordinary human muscle move loads far beyond its natural limit.
tornou-a fabricável ↓
Printing Press1440 AD (movable type in Europe) · 1440 ADA screw press and reusable cast-metal letters that turned a book from a year of a scribe's labor into a day's work — and made ideas cheap.
tornou-a possível ↓
The Fabrica's power was its 200-plus precise woodcut plates, reproducible identically in every copy — impossible without the press.
Human anatomy1543 (De Fabrica) · 1543 ADThe map of the human body as it actually is — bones, muscles, vessels, and organs described from direct dissection rather than from ancient authority. Andreas Vesalius fixed it in print in 1543, correcting a thousand years of inherited error.

Writing~3,200 BC · 3,200 BCMarks that store speech and records outside a human head — memory that survives its owner and travels without a messenger.

A census is only as good as its records; statistics needs the counts to survive in durable, comparable form across years.
Census and statistics1662 (Graunt's Observations) · 1662 ADThe practice of counting a population and then reasoning from the numbers — inferring how many people there are, how long they live, and how disease moves, from records that were never collected to answer those questions.

Reasoning from a sample of recorded deaths to a claim about the whole living population is inference under uncertainty — the probabilistic step Graunt took informally, just as the formal theory was being born.
Probability1654 (Pascal–Fermat correspondence) · 1654 ADThe mathematics of chance: a way to put a number on how likely an uncertain event is, and to compute the fair value of a bet by weighing each possible outcome by its probability. Uncertainty, long thought the province of fate, becomes something you can calculate.
tornou-a pensável ↓
Information is measured by how much a message reduces uncertainty, and uncertainty is a probability calculation — Shannon's entropy.
Information theory1948 AD · 1948 ADA mathematics of information itself. Claude Shannon showed that any message can be measured in bits, that a communication channel corrupted by noise still has an exact maximum error-free rate — its capacity — and that with the right coding you can transmit right up to that limit with an arbitrarily small error rate.
