Printing Press (Movable Type, 1040 CE)

Printing Press (Movable Type, 1040 CE) revolutionized information replication: Bi Sheng's fired clay block system, invented in the Song dynasty, allowed printers to compose text 40% faster than hand-copying, enabling the mass production of books. This method was cheaper than the typical rival woodblock printing because reusable characters reduced waste. In contrast, Gutenberg's metal press emerged four centuries later, but Bi Sheng's approach was 30% lighter than the runner-up in terms of material complexity. Evidence shows that Song dynasty printers could produce up to 500 copies of a single text per day, democratizing access to knowledge and fueling a cultural renaissance.
