No one talks about it? China inventing paper, printing and gunpowder is something every school child knows. I think I've heard about it about a million times. These facts are common knowledge; certainly paper and gunpowder.

Printing is an odd example; the reason Gutenberg was influential is not the reason most people think. He did not invent movable type. He invented systems for mass producing movable type, particularly technology for casting type blocks out of metal, instead of carving them out of wood. So yes, movable type was invented in China. But no, Gutenberg's contribution was not "stealing from the Chinese" (as has become popular to claim on the internet these days...) The root of this particular misconception is the general public's general ignorance of printing technology.
