71Logovisual technology — The term logovisual technology was introduced c. 2000 (Blake, Varney 1999) as a generic description for methods that structure texts to aid thinking. It arose in relation to a particular history of research and development with applications in… …
72Rent's Rule — pertains to the organization of computing logic, specifically the relationship between the number of external signal connections to a logic block (i.e., the number of pins ) with the number of logic gates in the logic block, and has been applied… …
73Enumerative geometry — In mathematics, enumerative geometry is the branch of algebraic geometry concerned with counting numbers of solutions to geometric questions, mainly by means of intersection theory.HistoryThe problem of Apollonius is one of the earliest examples… …
74Geometric graph theory — In mathematics, a geometric graph is a graph in which the vertices or edges are associated with geometric objects or configurations. Geometric graph theory is a specialization of graph theory that studies geometric graphs. Notable geometric… …
75Optical lattice — Simulation of an optical lattice potential. An optical lattice is formed by the interference of counter propagating laser beams, creating a spatially periodic polarization pattern. The resulting periodic potential may trap neutral atoms via the… …
76Molecular model — A molecular model, in this article, is a physical model that represents molecules and their processes. The creation of mathematical models of molecular properties and behaviour is molecular modelling, and their graphical depiction is molecular… …
77William Bunge — William Wheeler Bunge Jr. (born 1928, La Crosse, Wisconsin) is the American geographer active mainly as a quantitative geographer and spatial theorist but considering himself also as a radical, humanist and marxist geographer. He is often… …
78Hammerhead ribozyme — Taxobox | color=white name = Hammerhead Ribozyme image caption = Stylized rendering of the full length hammerhead ribozyme RNA molecule species = Catalytic RNAHammerhead RNAs are small self cleaving RNAs that have a conserved motif found in… …
79Molecular graph — In chemical graph theory and in mathematical chemistry, a molecular graph or chemical graph is a representation of the structural formula of a chemical compound in terms of graph theory. A chemical graph is a labeled graph whose vertices… …
80Risley Park Lanx — The Risley Park Lanx is a large silver dish of Roman origins, first discovered in 1729 in Risley Park, Derbyshire. Subsequently lost, later it apparently reemerged in the 1990s, a supposed heirloom of the Greenhalgh family. Bought by private… …
