In this sense, researchers and engineers may both be thought about technologists ; the 3 fields are typically considered as one for the functions of research and referral. The exact relations between science and technology, in specific, have actually been debated by researchers, historians, and policymakers in the late 20th century, in part because the argument can inform the funding of standard and applied science.
An expression of this approach could be found clearly in Vannevar Bush's writing on postwar science policy, Science The Limitless Frontier: "New items, brand-new markets, and more jobs need continuous additions to understanding of the laws of nature ... This vital new knowledge can be gotten only through basic scientific research." In the late-1960s, however, this view came under direct attack, leading towards efforts to money science for particular jobs (efforts withstood by the scientific neighborhood).
History Paleolithic (2. 5 Ma 10 ka) The use of tools by early humans was partially a process of discovery and of advancement. Early human beings developed from a types of foraging hominids which were already bipedal, with a brain mass approximately one third of modern-day human beings.

Stone tools A campfire, often utilized to prepare food Hominids started using primitive stone tools countless years back. The earliest stone tools were bit more than a fractured rock, however approximately 75,000 years back, pressure flaking supplied a way to make much finer work. Fire The discovery and usage of fire, a basic energy source with lots of profound usages, was a turning point in the technological development of humankind.
Fire, sustained with wood and charcoal, permitted early people to cook their food to increase its digestibility, improving its nutrient value and broadening the variety of foods that might be consumed. Clothes and shelter Other technological advances made during the Paleolithic age were clothes and shelter; the adoption of both technologies can not be dated exactly, but they were a crucial to humanity's development.
