Last year, the Colorado Department of Transportation counted 95,752 cars on I-25 at U.S. Highway 34 the day of the showdown, about 2,000 cars more than the week before, CDOT spokesman Jared Fiel said.
To make sure that they always had the upper hand, the Chinese invented many simple, yet effective tools of war. The Military inventions of ancient China were the kite, the wheelbarrow, naval mines, land mines, the flamethrower, the early form of mustard gas, the fire lance, paper armor, and the crossbow.
In 1267, a European writer made reference to gunpowder, and by 1280 the first recipes for the explosive mixture were published in the west. China's secret was out. Down through the centuries, Chinese inventions have had a profound effect on human culture. Items like paper, the magnetic compass, and silk have diffused around the world. None of those inventions, however, have had quite the impact that gunpowder has, for good and for bad.
