You: Gunpowder came from where? Al Gebr means what?
My question to you: Are these statements of equal meaning?
1. We were the first ...
2. We were among the first ...
No. My intent was to counter the (to me)ever-growing presumption of a superiority in European culture.
5. Cast Iron: China, Forth Century BC. By having good refractory clays for the construction of blast furnace walls, and the discovery of how to reduce the temperature at which iron melts by using phosphorus, the Chinese were able cast iron into ornamental and functional shapes. Coal, used as a fuel, was placed around elongated crucibles containing iron ore. This expertise allowed the production of pots and pans with thin walls. With the development of annealing in the third century, ploughshares, longer swords, and even buildings were eventually made of iron. In the West, blast furnaces are known to have existed in Scandinavia by the late eighth century AD, but cast iron was not widely available in Europe before 1380. 6. The Helicopter Rotor and the Propeller: China, Forth Century AD. By fourth century AD a common toy in China was the helicopter top, called the 'bamboo dragonfly'. The top was an axis with a cord wound round it, and with blades sticking out from the axis and set at an angle. One pulled the cord, and the top went climbing in the air. Sir George Cayley, the father of modern aeronautics, studied the Chinese helicopter top in 1809. The helicopter top in China led to nothing but amusement and pleasure, but fourteen hundred years later it was to be one of the key elements in the birth of modern aeronautics in the West. 7. The Decimal System: China, Fourteenth Century BC. An example of how the Chinese used the decimal system may be seen in an inscription from the thirteenth century BC, in which '547 days' is written 'Five hundred plus four decades plus seven of days'. The Chinese wrote with characters instead of an alphabet. When writing with a Western alphabet of more than nine letters, there is a temptation to go on with words like eleven. With Chinese characters, ten is ten-blank and eleven is ten-one (zero was left as a blank space: 405 is 'four blank five'), This was much easier than inventing a new character for each number (imagine having to memorize an enormous number of characters just to read the date!). Having a decimal system from the beginning was a big advantage in making mathematical advances. The first evidence of decimals in Europe is in a Spanish manuscript of 976 AD. 8. The Seismograph: China, Second Century AD. China has always been plagued with earthquakes and the government wanted to know where the economy would be interrupted. A seismograph was developed by the brilliant scientist, mathematician, and inventor Chang Heng (whose works also show he envisaged the earth as a sphere with nine continents and introduced the crisscrossing grid of latitude and longitude). His invention was noted in court records of the later Han Dynasty in 132 AD (the fascinating description is too long to reproduce here. It can be found on pgs. 162-166 of Temple's book). Modern seismographs only began development in 1848. |
