technology The techniques of engineering and applied science for commercial and industrial purposes. Many fundamental technologies – the smelting and working of metals, spinning and weaving of textiles, and the firing of clay, for example – were empirically developed at the dawn of civilization, long before any concept of science existed. With the advent, in about 3000 BC, of the first major civilizations in Egypt and Mesopotamia, many new technologies were developed – irrigation systems, road networks and wheeled vehicles, a pictographic form of writing, and new building techniques. Other civilizations subsequently became important technological centres, notably those of Greece and Rome, the Arab empire of the 7th to 10th centuries, and the Mayan, Aztec, and Toltec civilizations of the American continent. In the mid-16th century the focus of technological change shifted to Europe, with the beginning of the Scientific Revolution.
