Productivity improving technologies Wikipedia. This article is about the important technologies that have historically increased productivity. Productivity in general is a ratio of output to input in the production of goods and services. Productivity is increased by lowering the amount of labor, capital, energy or materials that go into producing economic goods. Increases in productivity are largely responsible for the increase in per capita living standards. HistoryeditProductivity improving technologies date back to antiquity, with rather slow progress until the late Middle Ages. Important examples of early to European medieval technology include the water wheel, the horse collar, the spinning wheel, the three field system after 1.

All of these technologies had been in use in China, some for centuries, before being introduced to Europe. Technological progress was aided by literacy and the diffusion of knowledge that accelerated after the spinning wheel spread to Western Europe in the 1. The spinning wheel increased the supply of rags used for pulp in paper making, whose technology reached Sicily sometime in the 1.

Cheap paper was a factor in the development of the movable typeprinting press, which lead to a large increase in the number of books and titles published. Books on science and technology eventually began to appear, such as the mining technical manual De Re Metallica, which was the most important technology book of the 1. Francis Bacon 1. Bacon stated that the technologies that distinguished Europe of his day from the Middle Ages were paper and printing, gunpowder and the magnetic compass, known as the Four great inventions. The Four great inventions important to the development of Europe were of Chinese origin. Other Chinese inventions included the horse collar, cast iron, an improved plow and the seed drill. See also List of Chinese inventions. Mining and metal refining technologies played a key role in technological progress. Vtol X-Plane Program. Much of our understanding of fundamental chemistry evolved from ore smelting and refining, with De Re Metallica being the leading chemistry text for 1. Railroads evolved from mine carts and the first steam engines were designed specifically for pumping water from mines. The significance of the blast furnace goes far beyond its capacity for large scale production of cast iron. The blast furnace was the first example of continuous production and is a countercurrent exchange process, various types of which are also used today in chemical and petroleum refining. Hot blast, which recycled what would have otherwise been waste heat, was one of engineerings key technologies. It had the immediate effect of dramatically reducing the energy required to produce pig iron, but reuse of heat was eventually applied to a variety of industries, particularly steam boilers, chemicals, petroleum refining and pulp and paper. Before the 1. 7th century scientific knowledge tended to stay within the intellectual community, but by this time it became accessible to the public in what is called open science. Near the beginning of the Industrial Revolution came publication of the Encyclopdie, written by numerous contributors and edited by Denis Diderot and Jean le Rond dAlembert 1. It contained many articles on science and was the first general encyclopedia to provide in depth coverage on the mechanical arts, but is far more recognized for its presentation of thoughts of the Enlightenment. Economic historians generally agree that, with certain exceptions such as the steam engine, there is no strong linkage between the 1. Descartes, Newton, etc. Industrial Revolution. However, an important mechanism for the transfer of technical knowledge was scientific societies, such as The Royal Society of London for Improving Natural Knowledge, better known as the Royal Society, and the Acadmie des Sciences. There were also technical colleges, such as the cole Polytechnique. Scotland was the first place where science was taught in the 1. Introduction To Scientific Programming And Simulation Using R Solutions Manual' title='Introduction To Scientific Programming And Simulation Using R Solutions Manual' />Joseph Black discovered heat capacity and latent heat and where his friend James Watt used knowledge of heat to conceive the separate condenser as a means to improve the efficiency of the steam engine. Probably the first period in history in which economic progress was observable after one generation was during the British Agricultural Revolution in the 1. However, technological and economic progress did not proceed at a significant rate until the English Industrial Revolution in the late 1. High productivity growth began during the late 1. Second Industrial Revolution. Most major innovations of the Second Industrial Revolution were based on the modern scientific understanding of chemistry, electromagnetic theory and thermodynamics and other principles known to a new profession of engineering. Major sources of productivity growth in economic historyedit. Volga River. Pushing was done with poles and manual pulling using overhanging tree branches. Horses were also used. New forms of energy and powereditBefore the industrial revolution the only sources of power were water, wind and muscle. Most good water power sites those not requiring massive modern dams in Europe were developed during the medieval period. In the 1. 75. 0s John Smeaton, the father of civil engineering, significantly improved the efficiency of the water wheel by applying scientific principles, thereby adding badly needed power for the Industrial Revolution. However water wheels remained costly, relatively inefficient and not well suited to very large power dams. Benot Fourneyrons highly efficient turbine developed in the late 1. Fourneyron type turbines can operate at 9. Hydro power continued to be the leading source of industrial power in the United States until past the mid 1. UK decades earlier. In 1. 71. 1 a Newcomen steam engine was installed for pumping water from a mine, a job that typically was done by large teams of horses, of which some mines used as many as 5. Animals convert feed to work at an efficiency of about 5, but while this was much more than the less than 1 efficiency of the early Newcomen engine, in coal mines there was low quality coal with little market value available. Fossil fuel energy first exceeded all animal and water power in 1. The role energy and machines replacing physical work is discussed in Ayres Warr 2. While steamboats were used in some areas, as recently as the late 1. Century thousands of workers pulled barges. Until the late 1. Heavy loads like 3. A young drawer pulling a coal tub along a mine gallery. Minecarts were more common than the skid shown. Railroads descended from minecarts. In Britain laws passed in 1. Excavation was done with shovels until the late 1. It was reported that a laborer on the western division of the Erie Canal was expected to dig 5 cubic yards per day in 1. Todays large electric shovels have buckets that can hold 1. Dynamite, a safe to handle blend of nitroglycerin and diatomaceous earth was patented in 1. Alfred Nobel. Dynamite increased productivity of mining, tunneling, road building, construction and demolition and made projects such as the Panama Canal possible. Steam power was applied to threshing machines in the late 1. There were steam engines that moved around on wheels under their own power that were used for supplying temporary power to stationary farm equipment such as threshing machines.
