Technology

Technology is the collection of techniques, skills, methods, and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge of techniques, processes, and the like, or it can be embedded in machines to allow for operation without detailed knowledge of their workings. Since ancient times humans relied on technology without such thing humanity won’t survive the harsh world that we are occupying. Technology came from the Greek word Techne "art, skill, cunning of hand". Technology is used since ancient time ages by ages so were going to name the important once.

First is the stone age. The first major technologies were tied to survival, hunting, and food preparation. Stone tools and weapons, fire, and clothing were technological developments of major importance during the stone age or Paleolithic. This technology help humans live and survive. Technology did end in the Paleolithic it continued to next age the bronze and copper age.

Second is the iron age. Iron age involved the adoption of iron smelting technology. It generally replaced bronze and made it possible to produce tools which were stronger, lighter and cheaper to make than bronze equivalents. 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. It was not possible to mass manufacture steel because high furnace temperatures were needed, but steel could be produced by forging bloomery iron to reduce the carbon content in a controllable way. Iron ores were much more widespread than either copper or tin. In Europe, large hill forts were built either as a refuge in time of war or sometimes as permanent settlements. In some cases, existing forts from the Bronze Age were expanded and enlarged. The pace of land clearance using the more effective iron axes increased, providing more farmland to support the growing population.

Third is the ancient age or technology. It was the growth of the ancient civilizations which produced the greatest advances in technology and engineering, advances which stimulated other societies to adopt new ways of living and how they governed their people. In this age the Egyptians, Indus valley civilization, Mesopotamians, Chinese, Greeks, Romans, Incaand Mayans contributed so much knowledge. The civilization on this ages contributed on mathematics, astronomy, medicine, agriculture, weaponry, philosophy, science and so much more. This contribution of theirs are still used even today example of this are the drainage system, gunpowder, compass, paper and so much more. With this age we are still dumb or perhaps ignorant without their contributions.

Last is medieval to modern. In this ages people focuses on science, weaponry, and economics. Innovations continued through the Middle Ages with innovations such as silk, the horse collar and horseshoes in the first few hundred years after the fall of the Roman Empire. Medieval technology saw the use of simple machines (such as the lever, the screw, and the pulley) being combined to form more complicated tools, such as the wheelbarrow, windmills and clocks. The Renaissance brought forth many of these innovations, including the printing press (which facilitated the greater communication of knowledge), and technology became increasingly associated with science, beginning a cycle of mutual advancement. The advancements in technology in this era allowed a steadier supply of food, followed by the wider availability of consumer goods. Starting in the United Kingdom in the 18th century, the Industrial Revolution was a period of great technological discovery, particularly in the areas of agriculture, manufacturing, mining, metallurgy, and transport, driven by the discovery of steam power. Technology took another step in a second industrial revolution with the harnessing of electricity to create such innovations as the electric motor, light bulb, and countless others. Scientific advancement and the discovery of new concepts later allowed for powered flight and advancements in medicine, chemistry, physics, and engineering. The rise in technology has led to skyscrapers and broad urban areas whose inhabitants rely on motors to transport them and their food supply. Communication was also greatly improved with the invention of the telegraph, telephone, radio and television. The late 19th and early 20th centuries saw a revolution in transportation with the invention of the airplane and automobile. The 20th century brought a host of innovations. In physics, the discovery of nuclear fission has led to both nuclear weapons and nuclear power. Computers were also invented and later miniaturized utilizing transistors and integrated circuits. Information technology subsequently led to the creation of the Internet, which ushered in the current Information Age. Humans have also been able to explore space with satellites (later used for telecommunication) and in manned missions going all the way to the moon. In medicine, this era brought innovations such as open-heart surgery and later stem cell therapy along with new medications and treatments. Complex manufacturing and construction techniques and organizations are needed to make and maintain these new technologies, and entire industries have arisen to support and develop succeeding generations of increasingly more complex tools. Modern technology increasingly relies on training and education – their designers, builders, maintainers, and users often require sophisticated general and specific training. Moreover, these technologies have become so complex that entire fields have been created to support them, including engineering, medicine, and computer science, and other fields have been made more complex, such as construction, transportation and architecture.
