Technology is the application of conceptual knowledge to achieve practical goals, especially in a reproducible way. [1] The word technology can also mean the products resulting from such efforts, [2] [3] including both tangible tools such as utensils or machines, and intangible ones such as software.
The term technology comes from the Greek word techne, meaning art and craft, and the word logos, meaning word and speech. It was first used to describe applied arts, but it is now used to describe advancements and changes that affect the environment around us. [1]
The new technology itself can interact with other technologies to form a new technology again. As the process of combining existing technologies is repeated again and again, the network of technologies grows. A described mechanism of technological change has been termed, “combinatorial evolution”. [2]
Discovery is the act of detecting something new, or something previously unrecognized as meaningful. In sciences and academic disciplines, discovery is the observation of new phenomena, new actions, or new events and involves providing new reasoning to explain the knowledge gathered through such observations, using knowledge previously acquired through abstract thought and from everyday ...
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 ...
1924: Edwin Hubble: the discovery that the Milky Way is just one of many galaxies; 1925: Erwin Schrödinger: Schrödinger equation (Quantum mechanics) 1925: Cecilia Payne-Gaposchkin: Discovery of the composition of the Sun and that hydrogen is the most abundant element in the Universe; 1927: Werner Heisenberg: Uncertainty principle (Quantum ...
These patterns can then be seen as a kind of summary of the input data, and may be used in further analysis or, for example, in machine learning and predictive analytics. For example, the data mining step might identify multiple groups in the data, which can then be used to obtain more accurate prediction results by a decision support system .
The importance of stone tools, circa 2.5 million years ago, is considered fundamental in the human development in the hunting hypothesis. [citation needed]Primatologist, Richard Wrangham, theorizes that the control of fire by early humans and the associated development of cooking was the spark that radically changed human evolution. [2]
