Technology

Defenition 
Technology is the making, modification, usage, and knowledge of tools, machines, techniques, crafts, systems, and methods of organization, in order to solve a problem. The human species use of technology began with the conversion of natural resources into simple tools.

   




History:

Paleolithic

 It extends from the earliest known use of stone tools. During the Paleolithic, humans grouped together in small societies such as bands, and subsisted by gathering plants and fishing, hunting or scavenging wild animals. The Paleolithic is characterized by the use of knapped stone tools, although at the time humans also used woods and bone tools.

Stone tools

Stone tool-dependent societies and cultures still exist today, most stone tools are associated with prehistoric, particularly Stone-Age cultures that have become extinct.Stone has been used to make a wide variety of different tools throughout history, including arrow heads, spearpoints and querns. Stone tools may be made of either ground stone or chipped stone, and a person who creates tools out of the latter is known as a flintknapper.



Fire
The discovery and utilization of fire, a simple energy source with many profound uses, was a turning point in the technological evolution of humankind. Fire, fueled with wood and charcoalallowed early humans to cook their food to increase its digestibility, improving its nutrient value and broadening the number of foods that could be eaten.

Clothing and shelter

Dwellings became more sophisticated and more elaborate; as early as 380,000 BC, humans were constructing temporary wood huts.Clothing, adapted from the fur and hides of hunted animals, helped humanity expand into colder regions.

Medieval technology examples

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.The late 19th and early 20th centuries saw a revolution in transportation with the invention of the steam-powered ship, train, airplane, and automobile.









Renaissance Technology

 The era is marked by profound technical advancements such as the printing press, linear perspective in drawing, patent law, double shell domes and Bastion fortresses. Sketchbooks from artisans of the period (Taccola and Leonardo da Vinci for example) give a deep insight into the mechanical technology then known and applied.
