China's Scientific Revolution
Among the engineering accomplishments of early China were matches, dry docks, the double-action piston pump, cast iron, the iron plough, the horse collar, the multi-tube seed drill, the wheelbarrow, the suspension bridge, the parachute, natural gas as fuel, the raised-relief map, the propeller, the sluice gate, and the pound lock. The Tang Dynasty (618 - 906 AD) in particular was a time of great innovation.
In the 7th century, book-printing was developed in China, Korea and Japan, using delicate hand-carved wooden blocks to print individual pages. The 9th century Diamond Sutra is the earliest known printed document. Movable type was also used in China for a time, but was abandoned because of the number of characters needed; it would not be until Johannes Gutenberg that the technique was reinvented in a suitable environment.
In addition to gunpowder, the Chinese also developed improved delivery systems for the Byzantine weapon of Greek fire, Meng Huo You and Pen Huo Qi first used in China c. 900. Chinese illustrations were more realistic than in Byzantine manuscripts, and detailed accounts from 1044 recommending its use on city walls and ramparts show the brass container as fitted with a horizontal pump, and a nozzle of small diameter. The records of a battle on the Yangtze near Nanjing in 975 offer an insight into the dangers of the weapon, as a change of wind direction blew the fire back onto the Song forces.

Famous quotes containing the words china, scientific and/or revolution:
“Anyone who tries to keep track of what is happening in China is going to end up by wearing all the skin of his left ear from twirling around on it.”
—Robert Benchley (1889–1945)
“We have our little theory on all human and divine things. Poetry, the workings of genius itself, which, in all times, with one or another meaning, has been called Inspiration, and held to be mysterious and inscrutable, is no longer without its scientific exposition. The building of the lofty rhyme is like any other masonry or bricklaying: we have theories of its rise, height, decline and fall—which latter, it would seem, is now near, among all people.”
—Thomas Carlyle (1795–1881)
“History in the making is a very uncertain thing. It might be better to wait till the South American republic has got through with its twenty-fifth revolution before reading much about it. When it is over, some one whose business it is, will be sure to give you in a digested form all that it concerns you to know, and save you trouble, confusion, and time. If you will follow this plan, you will be surprised to find how new and fresh your interest in what you read will become.”
—Anna C. Brackett (1836–1911)
