Sail und Analytische Maschine: was sie gemeinsam haben
- Schritt 1. Sail — ist Teil von — Sailing ship. Sails drive the ship.
- Schritt 2. Sailing ship — nutzt — Mercator projection. Navigating along straight rhumb lines.
- Schritt 3. Mercator projection — nutzt — Gutenberg printing press. Maps were printed in large numbers.
- Schritt 4. Gutenberg printing press — funktioniert wie — Jacquard loom. An analogy, not proven influence: both set type and a chain of punched cards are a replaceable pattern that a machine reproduces over and over.
- Schritt 5. Jacquard loom — inspirierte — Analytische Maschine. Babbage borrowed Jacquard’s punched cards directly for entering operations and data; Ada Lovelace compared the machine to the Jacquard loom.
