Technology is typically a consequence of science and engineering, although technology as a human activity precedes the two fields. For example, science might study the circulation of electrons in electrical conductors by utilizing already-existing tools and knowledge. This new-found knowledge might then be utilized by engineers to develop brand-new tools and makers such as semiconductors, computers, and other kinds of innovative technology.
The exact relations in between science and innovation, in specific, have been debated by researchers, historians, and policymakers in the late 20th century, in part due to the fact that the debate can inform the financing of fundamental and used science. In the immediate wake of The second world war, for instance, it was extensively thought about in the United States that technology was simply "applied science" and that to money basic science was to gain technological outcomes in due time.
This essential new understanding can be acquired just through fundamental scientific research." In the late-1960s, however, this view came under direct attack, leading towards initiatives to money science for specific tasks (initiatives resisted by the scientific community). The issue remains contentious, though the majority of analysts resist the model that technology is an outcome of scientific research study.
Early people progressed from a species of foraging hominids which were currently bipedal, with a brain mass around one third of modern people. Tool use stayed reasonably the same for most of early human history. Around 50,000 years earlier, making use of tools and complex set of behaviors emerged, believed by many archaeologists to be linked to the development of totally contemporary language.
The earliest stone tools were little bit more than a fractured rock, but around 75,000 years ago, pressure flaking supplied a method to make much finer work. The discovery and use of fire, an easy energy source with numerous profound usages, was a turning point in the technological advancement of humankind.
Fire, sustained with wood and charcoal, permitted early people to prepare their food to increase its digestibility, enhancing its nutrient worth and widening the variety of foods that could be consumed. Other technological advances made during the Paleolithic period were clothing and shelter; the adoption of both technologies can not be dated exactly, however they were an essential to mankind's development.
