==== East Asia ====
==== Indian subcontinent ====
==== Islamic world ====
The Muslim caliphates united large areas that had previously traded little with one another, including the Middle East, North Africa, Central Asia, the Iberian Peninsula, and parts of the Indian subcontinent. The science and technology of earlier empires in the region, including the Mesopotamian, Egyptian, Persian, Hellenistic, and Roman empires, were inherited by the Muslim world, where Arabic replaced Syriac, Persian, and Greek as the region's lingua franca. Significant advances were made in the region during the Islamic Golden Age (8th–16th centuries). The Arab Agricultural Revolution occurred during this period. It was a transformation in agriculture from the 8th to the 13th century in the Islamic region of the Old World. The economy established by Arab and other Muslim traders across the Old World enabled the diffusion of many crops and farming techniques throughout the Islamic world, as well as the adaptation of crops and techniques from and to regions outside it. Advances were made in animal husbandry, irrigation, and farming, with the help of new technology such as the windmill. These changes made agriculture much more productive, supporting population growth, urbanisation, and greater social stratification. Muslim engineers in the Islamic world made extensive use of hydropower, as well as early uses of tidal power and wind power. fossil fuels such as petroleum, and large factory complexes (tiraz in Arabic). A variety of industrial mills were employed in the Islamic world, including fulling mills, gristmills, hullers, sawmills, ship mills, stamp mills, steel mills, and tide mills. By the 11th century, every province throughout the Islamic world had these industrial mills in operation. Muslim engineers also employed water turbines and gears in mills and water-raising machines, and pioneered the use of dams as a source of water power, used to provide additional power to watermills and water-raising machines. Many of these technologies were transferred to medieval Europe. Wind-powered machines used to grind grain and pump water, the windmill and wind pump, first appeared in what are now Iran, Afghanistan, and Pakistan by the 9th century. They were used to grind grains and draw up water, and used in the gristmilling and sugarcane industries. Sugar mills first appeared in the medieval Islamic world. They were first driven by watermills, and then windmills from the 9th and 10th centuries in what are today Afghanistan, Pakistan and Iran. Crops such as almonds and citrus fruit were brought to Europe through Al-Andalus, and sugar cultivation was gradually adopted across Europe. Arab merchants dominated trade in the Indian Ocean until the arrival of the Portuguese in the 16th century. The Muslim world adopted papermaking from China. The earliest paper mills appeared in Abbasid-era Baghdad during 794–795. The knowledge of gunpowder was also transmitted from China via predominantly Islamic countries, where formulas for pure potassium nitrate were developed. The spinning wheel was invented in the Islamic world by the early 11th century. It was later widely adopted in Europe, where it was adapted into the spinning jenny, a key device during the Industrial Revolution. The crankshaft was invented by Al-Jazari in 1206, and is central to modern machinery such as the steam engine, internal combustion engine and automatic controls. The camshaft was also first described by Al-Jazari in 1206. Early programmable machines were also invented in the Muslim world. The first music sequencer, a programmable musical instrument, was an automated flute player invented by the Banu Musa brothers and described in their Book of Ingenious Devices in the 9th century. In 1206, Al-Jazari invented programmable automata/robots. He described four automaton musicians, including two drummers operated by a programmable drum machine, each capable of playing different rhythms and drum patterns. The castle clock, a hydropowered mechanical astronomical clock invented by Al-Jazari, was an early programmable analog computer. In the Ottoman Empire, a practical impulse steam turbine was invented in 1551 by Taqi ad-Din Muhammad ibn Ma'ruf in Ottoman Egypt. He described a method for rotating a spit using a jet of steam acting on rotary vanes around the periphery of a wheel. Known as a steam jack, a similar device for rotating a spit was also later described by John Wilkins in 1648.
==== Medieval Europe ====
While medieval technology has long been depicted as a step backward in the evolution of Western technology, a generation of medievalists (such as the American historian of science Lynn White) stressed, from the 1940s onwards, the innovative character of many medieval techniques. Genuine medieval contributions include, for example, mechanical clocks, spectacles, and vertical windmills. Medieval ingenuity was also displayed in the invention of seemingly inconspicuous items such as the watermark and the functional button. In navigation, the foundation to the subsequent Age of Discovery was laid by the introduction of pintle-and-gudgeon rudders, lateen sails, the dry compass, the horseshoe, and the astrolabe. Significant advances were also made in military technology with the development of plate armour, steel crossbows and cannons. The Middle Ages are perhaps best known for their architectural heritage: While the invention of the rib vault and pointed arch gave rise to the high rising Gothic style, the ubiquitous medieval fortifications gave the era the almost proverbial title of the 'age of castles'. Papermaking, a 2nd-century Chinese technology, was carried to the Middle East when a group of Chinese papermakers was captured in the 8th century. Papermaking technology was spread to Europe by the Umayyad conquest of Hispania. A paper mill was established in Sicily in the 12th century. In Europe, the fiber to make pulp for making paper was obtained from linen and cotton rags. Lynn Townsend White Jr. credited the spinning wheel with increasing the supply of rags, which led to cheap paper, which was a factor in the development of printing.
