The concept of the "state of the art" originated at the beginning of the 20th century. [3] The earliest use of the term "state of the art" documented by the Oxford English Dictionary dates back to 1910, from an engineering manual by Henry Harrison Suplee (1856 – after 1943), an engineering graduate (University of Pennsylvania, 1876), titled The Gas Turbine: Progress in the Design and ...
The term bleeding edge has been used to refer to some new technologies, formed as an allusion to the similar terms "leading edge" and "cutting edge". It tends to imply even greater advancement, albeit at an increased risk because of the unreliability of the software or hardware . [ 43 ]
An edged weapon, [1] or bladed weapon, is a melee weapon with a cutting edge. [2] Bladed weapons include swords, daggers, knives, and bayonets. Edged weapons are used to cut, hack, or slash; some edged weapons (such as many kinds of swords) may also permit thrusting and stabbing.
short chisel with beveled sides and straight edge for creating joints. Carving chisels used for intricate designs and sculpting; cutting edges are many; such as gouge, skew, parting, straight, paring, and V-groove. Corner chisel resembles a punch and has an L-shaped cutting edge. Cleans out square holes, mortises and corners with 90 degree angles.
The opposite of high tech is low technology, referring to simple, often traditional or mechanical technology; for example, a slide rule is a low-tech calculating device. [4] [5] [6] When high tech becomes old, it becomes low tech, for example vacuum tube electronics. Further, high tech is related to the concept of mid-tech, that is a balance ...
Sharpening these implements can be expressed as the creation of two intersecting planes which produce an edge that is sharp enough to cut through the target material. For example, the blade of a steel knife is ground to a bevel so that the two sides of the blade meet. This edge is then refined by honing until the blade is capable of cutting.
List of emerging technologies – new fields of technology, typically on the cutting edge. Examples include genetics, robotics, and nanotechnology (GNR) Artificial intelligence – computer mental abilities, especially those that previously belonged only to humans, such as speech recognition, natural language generation, etc.
It is so called because the triangular cross section gives a flat back edge opposite the cutting edge. [2] Later examples often have a "false edge" on the back near the tip, which was in many cases sharpened to make an actual edge and facilitate thrusting attacks.
