In technologically development, the story is much different
(see Burke (1978) for more descriptions of these
innovations). There have been many Western innovations that
have their basis in China, particularly those in printing (paper,
block printing, and moveable-type printing), agricultural
technology (irrigation systems), mechanical engineering
(clockwork, iron, and lead manufacturing, efficient harnesses),
and martial (gunpowder, the precursors to the barrel gun, and
cannons) technology.
