Technology is a term that involves the scientific and technical knowledge and the tools, processes and materials created and / or used from this knowledge. Depending on the context, technology can be: The tools and machines that help solve problems, techniques, knowledge, methods, materials, tools and processes used to solve problems or at least facilitate the solution of the same; A method or process and construction work (such as technology, manufacturing, technology, infrastructure or space technology); The application of resources for problem solving; The term technology can also be used to describe the level of scientific knowledge, mathematical and technical of a particular culture, in economy, technology is the current state of our knowledge of how to combine resources to produce desired (and our knowledge of what can be produced). The technology is, in general, the meeting between science and engineering. Being a term that includes the tools and processes from simple, such as a wooden spoon, and fermentation of the grape respectively, to the tools and processes more complex already created by human beings, such as the International Space Station and desalination of seawater respectively . Often, the technology conflicts with some natural concerns of our society, such as unemployment, pollution and many other issues ecological, sociological and philosophical. Technology and economy. There is a very tênue balance between the advantages and disadvantages that the advance of technology brings to society. The main advantage is reflected in industrial production: technology makes production faster and bigger and, thus, the end result is a product cheaper and with higher quality. The disadvantages that technology brings are so disturbing that almost outweigh the advantages, one is the pollution that, if not controlled in time, moves to a table irreversible. Another disadvantage is that the unemployment caused by the intensive use of machinery in industry, agriculture and trade. This type of unemployment, in which the work of man is replaced by the work of machines, called structural unemployment. One of the countries that suffer most with this problem is that Japan, one of the main reasons for the growth of the economy of this country has freado from the decade of 90 was, rightly, structural unemployment. Science and Technology Science and technology have always been very close to each other. Generally, the science is the study of nature strictly in accordance with the scientific method. The technology, in turn, is the application of such knowledge to achieve a practical result. As an example, the science could study the flow of electrons in an electric current. This knowledge has been and continues to be used for the manufacture of electronic products such as semiconductors, computers and other products of high technology.
This close relationship between science and technology contributes decisively to the increasing specialization of scientific branches. For example, the physics is divided in several other smaller branches as the acoustics and mechanics, and these branches in turn suffered successive divisions. The result is the appearance of very specific branches scientific and especially intended to improve the technology, according to this query can cite the aerodynamics, the geotecnia, hydrodynamics, petrologia and terramecânica. History The history of the technology of the technology is almost as old as the history of mankind, and that follows from when humans began using tools for hunting and protection. The history of technology has thus built a chronology of the use of natural resources because, to be created, all the tools needed, before anything, the use of a natural resource appropriate. The history of technology follows a progression from simple tools and sources of energy for simple and complex tools of the energy complex, as follows: Technologies oldest naturalresources converted into simple tools. The olderprocesses, such as rock art and scraping of stones, and the older tools such as stone Splintered grain and wheel are simple means for the conversion of raw materials and "raw" into useful products. The anthropologists found many homes and tools humanities made directly from natural resources. The discovery and subsequent use of fire was a key point in the technological evolution of the man, allowing a better use of foods and the use of natural resources which need the heat to be useful. The wood of firewood and coal are among the first materials used as fuel. The wood, clay and rock (such as limestone) were among the most advanced materials to be processed by the fire, to make weapons, ceramics, bricks and cement, among other materials. Improvements continued with the furnace, allowing the ability to melt and forge the metal (such as copper, 8000 BC.), And possibly the discovery of alloys such as bronze (4000 BC). The first uses the iron and steel dating from 1400 aCu
