Gutenberg printing press und mechanical clock: was sie gemeinsam haben
- Schritt 1. Gutenberg printing press — nutzt — Ink. An impression needs ink; Gutenberg used an oil-based one.
- Schritt 2. Ink — wird verwendet in — Inkjet printer. Ink.
- Schritt 3. Inkjet printer — nutzt — Piezoelectric effect. Piezo heads eject droplets.
- Schritt 4. Piezoelectric effect — wird verwendet in — Quartz clock. The quartz resonator vibrates thanks to the piezoelectric effect.
- Schritt 5. Quartz clock — entwickelte sich aus — Mechanical clock. Quartz clocks replaced mechanical ones: a vibrating quartz crystal took the place of the pendulum and balance.
