Science, engineering, and innovation The difference in between science, engineering, and innovation is not constantly clear. Science is systematic understanding of the physical or material world acquired through observation and experimentation. Technologies are not generally solely products of science, because they have to satisfy requirements such as energy, usability, and security.

The advancement of innovation may draw upon lots of fields of understanding, including clinical, engineering, mathematical, linguistic, and historic knowledge, to attain some useful result. Technology is typically a repercussion of science and engineering, although technology as a human activity precedes the two fields. For instance, science might study the circulation of electrons in electrical conductors by utilizing already-existing tools and knowledge.

In this sense, scientists and engineers may both be considered technologists []; the three fields are frequently thought about as one for the purposes of research and reference. The specific relations in between science and technology, in particular, have been disputed by scientists, historians, and policymakers in the late 20th century, in part because the dispute can inform the financing of basic and applied science.

An articulation of this viewpoint might be discovered explicitly in Vannevar Bush's writing on postwar science policy, Science The Limitless Frontier: "New products, brand-new industries, and more jobs require constant additions to understanding of the laws of nature ... This essential brand-new knowledge can be obtained just through standard clinical research." In the late-1960s, however, this view came under direct attack, leading towards efforts to fund science for particular jobs (initiatives resisted by the scientific community).

History Paleolithic (2. 5 Ma 10 ka) The use of tools by early humans was partially a process of discovery and of advancement. Early humans developed from a types of foraging hominids which were already bipedal, with a brain mass roughly one third of modern-day humans. Tool usage remained reasonably the same for the majority of early human history.

Stone tools A campfire, often utilized to cook food Hominids began using primitive stone tools countless years back. The earliest stone tools were little more than a fractured rock, but roughly 75,000 years earlier, pressure flaking supplied a way to make much finer work. Fire The discovery and usage of fire, a basic energy source with many extensive usages, was a turning point in the technological evolution of mankind.
