The chain-linked model or Kline model of innovation was introduced by mechanical engineer Stephen J. Kline in 1985, [1] and further described by Kline and economist Nathan Rosenberg in 1986. [2] The chain-linked model is an attempt to describe complexities in the innovation process. The model is regarded as Kline's most significant contribution ...
The most notable example of Maya astronomical observatories is Caracol, in Chichén Itzá. In 1975, archaeoastronomers Anthony F. Aveni and Horst Hartung surveyed the site and suggested that ancient Maya astronomers used the structure to observe the planet Venus. The Maya, as well as other Mesoamerican culture groups, used Venus to set times ...
Pace of innovation is the speed at which technological innovation or advancement is occurring, with the most apparent instances being too slow or too rapid. Both these rates of innovation are extreme and therefore have effects on the people that get to use this technology.
Productivity-improving technologies date back to antiquity, with rather slow progress until the late Middle Ages. Important examples of early to medieval European technology include the water wheel, the horse collar, the spinning wheel, the three-field system (after 1500 the four-field system—see crop rotation) and the blast furnace.
Technological change (TC) or technological development is the overall process of invention, innovation and diffusion of technology or processes. [1] [2] In essence, technological change covers the invention of technologies (including processes) and their commercialization or release as open source via research and development (producing emerging technologies), the continual improvement of ...
Innovation is related to, but not the same as, invention: [4] innovation is more apt to involve the practical implementation of an invention (i.e. new / improved ability) to make a meaningful impact in a market or society, [5] and not all innovations require a new invention. [6] Technical innovation often manifests itself via the engineering ...
Wheel of Fortune‘s Teachers’ Week has turned into an unexpected English lesson. During the game show’s annual celebration of educators, several eagle-eyed viewers (as first noted by TV ...
After a recession at the end of the 1830s and a general slowdown in major inventions, the Second Industrial Revolution was a period of rapid innovation and industrialization that began in the 1860s or around 1870 and lasted until World War I. It included rapid development of chemical, electrical, petroleum, and steel technologies connected with ...
