In this sense, scientists and engineers might both be considered technologists ; the three fields are typically considered as one for the purposes of research study and referral. The specific relations between science and technology, in particular, have actually been discussed by scientists, historians, and policymakers in the late 20th century, in part because the dispute can inform the funding of standard and used science.
An articulation of this philosophy might be discovered explicitly in Vannevar Bush's treatise on postwar science policy, Science The Endless Frontier: "New products, brand-new markets, and more jobs need constant additions to understanding of the laws of nature ... This essential brand-new knowledge can be obtained only through fundamental clinical research study." In the late-1960s, nevertheless, this view came under direct attack, leading towards initiatives to money science for specific jobs (initiatives withstood by the clinical community).
History Paleolithic (2. 5 Ma 10 ka) Using tools by early humans was partly a process of discovery and of advancement. Early human beings evolved from a types of foraging hominids which were already bipedal, with a brain mass roughly one third of modern-day people. Tool use stayed fairly the same for most of early human history.

Stone tools A campfire, frequently used to prepare food Hominids began using primitive stone tools countless years back. The earliest stone tools were little more than a fractured rock, but approximately 75,000 years ago, pressure flaking provided a way to make much finer work. Fire The discovery and use of fire, a simple energy source with lots of extensive uses, was a turning point in the technological development of mankind.
Fire, sustained with wood and charcoal, enabled early humans to cook their food to increase its digestibility, improving its nutrient worth and widening the variety of foods that might be eaten. Clothing and shelter Other technological advances made throughout the Paleolithic age were clothing and shelter; the adoption of both technologies can not be dated exactly, however they were a key to humanity's progress.
