The, history of Science and Technology in the Indian subcontinent begins, with prehistoric human, activity, in the Indus Valley Civilisation. Two early states and empires. Following. Independence Science, and Technology in the republic of india has included, automobile, engineering, information, technology. Communications. As well as space polar and nuclear, sciences. Topic. Prehistory. By. 5,500. BCE, a number, of sites similar, to morgue are had appeared forming, the basis of later Chalcolithic, cultures the. Inhabitants, of these sites maintain, trading, relations, with Near East and Central Asia irrigation. Was developed, in the Indus Valley Civilisation. By around, 4500. BCE, the. Size and prosperity, of the Indus civilization. Grew as a result of this innovation which eventually led, to more planned settlements, making use of drainage, and sewerage. Sophisticated. Irrigation, and water storage systems, were developed by the Indus Valley Civilisation. Including, artificial reservoirs. At Gerner dated, to 3000, BCE, and an early canal irrigation system. From C. 2600. BCE, cotton. Was cultivated, in the region by the 5th 4th millennia, BCE. Sugarcane. Was originally, from tropical, South and Southeast, Asia different. Species likely originated. In different locations, with sbar berry originating. In India and s edule in s efficient, Arum coming from New Guinea the inhabitants, of the Indus Valley developed. A system of standardization, using, weights and measures evident, by the excavations. Made at the Indus Valley sites, this. Technical, standardization. Enabled, gauging devices, to be effectively, used in angular, measurement, and measurement, for construction. Calibration. Was also found in measuring, devices along, with multiple subdivisions. In case of some devices, one. Of the earliest known Docs has at Lothal, 2,400. BCE located. Away from the main current, to avoid deposition. Of silt, modern. Oceanographers. Have observed, that the Harappans must, have possessed knowledge relating, to tides in order to build such a dock on the ever-shifting course, of the sabra mattie as well as exemplary, hydrography. And maritime, engineering. Excavations. At Bala cot c2, 500, 1, 900, BCE, present-day. Pakistan have, yielded evidence, of an early furnace the. Furnace was, most likely used for the manufacturing. Of ceramic, objects. Ovens. Dating, back to the civilizations. Mature, phase see 2 500 1, 900. BCE, were, also excavated, at Bala khat. The calla baingan archaeological.
