This article is about the topic of technology in history. For the publication, see History of Technology (magazine). The history of technology is the history of the invention of tools and techniques for doing practical things. Its modern history is intimately related with the history of science, as the discovery of new background knowledge has enabled us to create new things, and conversely, many scientific endeavors have become possible through technologies which assist humans to travel to places we could not otherwise go, and probe the nature of the universe in more detail than our natural senses allow. Technological artifacts are products of an economy, a force for economic growth, and a large part of everyday life. Technological innovations affect, and are affected by, a society's cultural traditions. They also are a means to develop and project military power. Early technology
Stone Age During the Stone Age, all humans were hunter-gatherers, a lifestyle which involved limited use of tools and few if any permanent settlements. The first major technologies, then, were tied to survival, hunting, and food preparation in this environment. Fire, stone tools and weapons, and clothing were technological developments of major importance during this period. Stone Age cultures developed music, and engaged in organized warfare. A subset of Stone Age people developed ocean-worthy outrigger ship technology, leading to an eastward migration across the Malay archipelago, across the Indian ocean to Madagascar and also across the Pacific Ocean, which required knowledge of the ocean currents, weather patterns, sailing, celestial navigation, and star maps. The early Stone Age is described as Epipaleolithic or Mesolithic. The former is generally used to describe the early Stone Age in areas with limited glacial impact. The later Stone Age, during which the rudiments of agricultural technology were developed, is called the Neolithic period. Copper, Bronze, and Iron Age The Stone Age developed into the Bronze Age after the Neolithic Revolution. The Neolitic Revolution involved radical changes in agricultural technology which included development of agriculture, animal domestication, and the adoption of permanent settlements. These combined factors made possible the development of metal smelting, with copper and later bronze, being the metals of choice. This technological trend began in the Fertile Crescent, and spread outward over time. It should be noted that these developments were not, and still are not, universal. The Three-age system does not accurately describe the technology history of groups outside of Eurasia, and does not apply at all in the case of some populations, such as the Spinifex People, the Sentinelese, and various Amazonian tribes, which still make use of Stone Age technology, and have not developed agricultural or metallurgical technology. The Iron Age involved the adoption of iron forging technology. It generally replaced bronze, and allowed tools which were stronger and less costly to make. In many Eurasian cultures, the Iron Age was the last major step before the development of written language, though again this was not universally the case. Although paleolitic cultures left no written records, the shift from nomadic life to settlement and agriculture can be inferred from a range of archeological evidence. Such evidence includes ancient tools*, cave paintings, and other prehistoric art, such as the Venus of Willendorf. Human remains also provide direct evidence, both through the examination of bones, and the study of mummies. Though concrete evidence is limited, scientists and historians have been able to form significant inferences about the lifestyle and culture of various prehistoric peoples, and the role technology played in their lives. Ancient Egypt The Egyptians invented and used many simple machines, such as the ramp and the lever, to aid construction processes. Egyptian paper, made from papyrus, and pottery was mass produced and exported throughout the Mediterranean basin. The wheel, however, did not arrive until foreign invaders introduced the chariot. Tribal Europe By 1000 BC - 500 BC, the Germanic tribes had a bronze age civilization, while the Celts were in the iron age by the time of the Hallstatt culture. Their cultures collided with the military and agricultural practices of the Romans, leading the Europeans to appropriate both social and technological processes of the Romans. Ancient Greece The Greeks invented many technologies, and improved upon preexisting technologies, particularly during the Hellenistic period. Heron of Alexandria invented a basic steam engine and demonstrated knowledge of mechanic and pneumatic systems. Archimedes invented several machines. The Greeks were unique in pre-industrial times in their ability to combine scientific research with the development of new technologies. One example is the Archimedean screw; this technology was first conceptualized in mathematics, then built. Other technologies invented by Greek scientists include the ballistae, and primitive analog computers like the Antikythera mechanism and the piston pump.*. Greek architects were responsible for the first true domes, and were the first to explore the Golden ratio and its relationship with geometry and architecture. Ancient Rome
Ancient India The Indus Valley Civilization, situated in a resource-rich area, is notable for its early application of city planning and sanitation technologies. Cites in the Indus Valley offer some of the first examples of closed gutters, public baths, and communal graineries. The Takshashila University was an important seat of learning in the ancient world. It was the center of education for scholars from all over Asia. Many Greek, Persian and Chinese students studied here under great scholars including Kautilya, Panini, Jivaka, Vishnu Sharma. Ancient India was also at the forefront of seafaring technology - a panel found at Mohenjodaro, depicts a sailing craft. Ship construction is vividly described in the Yukti Kalpa Taru, an ancient Indian text on Ship-building. The Yukti Kalpa Taru, compiled by Bhoja Narapati is concerned with ship-building. (The Yukti Kalpa Taru had been translated and published by Prof. Aufrecht in his 'Catalogue of Sanskrit Manuscripts'). Indian construction and architecture, called 'Vaastu Shastra', suggests a thorough understanding or materials engineering, hydrology, and sanitation. Ancient Indian culture was also pioneering in its use of vegetable dyes, cultivating plants including indigo and cinnabar. Many of the dyes were used in art and sculpture. The use of perfumes demonstrates some knowledge of chemistry, particularly distillation and purification processes. Ancient China
Inca The engineering skills of the Inca were great, even by today's standards. An example is the use of pieces weighing in upwards of one ton in their stonework (e.g., Machu Picchu in Peru), placed together so that not even a blade can fit in-between the cracks. The villages used irrigation canals and drainage systems, making agriculture very efficient. While some claim that the Incas were the first inventors of hydroponics, their agricultural technology was still soil based, if advanced. This technology, including tiered farm plots, allowed significant yields from steeply sloped or otherwise unproductive land. Maya Though the Maya civilization had no metalurgy or wheel technology, they developed complex writing and astrological systems, and created sculptural works in stone and flint. Like the Inca, the Maya also had command of fairly advanced agricultural and construction technology. Muslims see www.muslimheritage.com (if some one has some meterial about islamic technology put it here) Europe The fall of the Roman Empire slowed innovation in some areas, and resulted in the total loss of technologies (such as the technology to make concrete) in others. By the fall of Rome, heavy chain armor was in general use by the armies of Rome as the lorica segmentata armor fell out of use, and for nearly a thousand years afterward, until it was substituted by plate armor. Medieval See main article: Medieval technology While it is generally thought that the Middle Ages were a step backwards in western technology, with Alchemy replacing true scientific practice, there were significant advances made in some areas during this time. Timekeeping which had been done by hand, by priests, and then for commerce, with watchmen to note time, as part of their duties, was advanced as the tabulation of the equinoxes became standardized, and the sandglass was replaced with the water clock, whcih became more accurate over time. For ships at sea, boys were used to turn the sandglasses, and to call the hours. The use of the pendulum, ratchet and gear allowed the towns of Europe to create mechanisms to display the time on their respective town clocks; by the time of the scientific revolution, the clocks became miniaturized enough for families to share a personal clock, or perhaps a pocket watch. At first, only kings could afford them. Age of Exploration The sailing ship (Nau or Carrack) enabled the Age of Exploration with the European colonization of the Americas, epitomized by Francis Bacon's New Atlantis. European powers rediscovered the idea of the Civil code, lost since the time of the Ancient Greeks. Industrial Revolution Main article: Industrial Revolution The British Industrial Revolution is characterised by developments in the areas of textile manufacturing, metallurgy and transport driven by the development of the steam engine. 19th century The 19th century saw major developments in transportation, construction, and communication technologies. The Steam Engine which had existed since the early 18th century, was practically applied to both steamboat and railway transportation. Telegraphy also developed into a practical technology in the 19th century. Other technologies were explored for the first time, including the Incandescent light bulb. The Portsmouth Block Mills was where manufacture of ships' pulley blocks by all-metal machines first took place and instigated the age of mass production. Machine tools used by engineers to manufacture other machines began in the first decade of the century, notably by Richard Roberts and Joseph Whitworth. Steamships were eventually completely iron-clad, and played a role in the opening of Japan and China to trade with the West. Mechanical computing was envisioned by Charles Babbage but did not come to fruition. The Second Industrial Revolution at the end of the 19th century saw rapid development of chemical, electrical, petroleum, and steel technologies connected with highly structured technology research. 20th century 20th Century technology has developed rapidly. At the outset of the 20th century, Radio, and Radar were key technologies. It is possible that electronic computing would have developed as rapidly without the wars of the twentieth century. Nuclear power, developed after the Manhattan project, is another important but controversial technology. Transport by rocketry: most work occurred in the U.S. (Goddard), Russia (Tsiolkovsky) and Germany (Oberth). Making use of computers and advanced research labs, modern scientists have Recombinant DNA. Measuring technological progress Many sociologists and anthropologists have created social theories dealing with social and cultural evolution. Some, like Lewis H. Morgan, Leslie White, and Gerhard Lenski, declare technological progress to be the primary factor driving the development of human civilisation. Morgan's concept of three major stages of social evoluton (savagery, barbarism, and civilization) can be divided by technological milestones, like fire, the bow, and pottery in the savage era, domestication of animals, agriculture, and metalworking in the barbarian era and the alphabet and writing in the civilisation era. Instead of specific inventions, White decided that the measure by which to judge the evolution of culture was energy. For White "the primary function of culture" is to "harness and control energy." White differentiates between five stages of human development: In the first, people use energy of their own muscles. In the second, they use energy of domesticated animals. In the third, they use the energy of plants (agricultural revolution). In the fourth, they learn to use the energy of natural resources: coal, oil, gas. In the fifth, they harness nuclear energy. White introduced a forumula P=E Lenski takes a more modern approach and focuses on information. The more information and knowledge (especially allowing the shaping of natural environment) a given society has, the more advanced it is. He identifies four stages of human development, based on advances in the history of communication. In the first stage, information is passed by genes. In the second, when humans gain sentience, they can learn and pass information through by experience. In the third, the humans start using signs and develop logic. In the fourth, they can create symbols, develop language and writing. Advancements in the technology of communication translates into advancements in the economic system and political system, distribution of goods, social inequality and other spheres of social life. He also differentiates societies based on their level of technology, communication and economy: 1) hunters and gatherers, 2) simple agricultural, 3) advanced agricultural, 4) industrial 5) special (like fishing societies). Finally, from the late 1970s sociologists and anthropologists like Alvin Toffler (author of Future Shock), Daniel Bell and John Naisbitt have approached the theories of post-industrial societies, arguing that the current era of industrial society is coming to an end, and services and information are becoming more important than industry and goods. Some of the more extreme visions of the post-industrial society, especially in fiction, are strikingly similar to the visions of near and post-Singularity societies.
