Regularization. v. t. e. In theoretical physics, the term renormalization group ( RG) refers to a formal apparatus that allows systematic investigation of the changes of a physical system as viewed at different scales. In particle physics, it reflects the changes in the underlying force laws (codified in a quantum field theory) as the energy ...
Firearms, weapons. Owner. Umarex. Röhm Gesellschaft, often referred to as RG, is a German brand of firearms and related shooting equipment. RG developed as a diversification of Röhm GmbH in the 1950s. After 1968, RG Industries was established as a US division in Miami and operated until 1986. In 2010, the RG brand was acquired by Umarex GmbH ...
Radius of gyration. Radius of gyration or gyradius of a body about the axis of rotation is defined as the radial distance to a point which would have a moment of inertia the same as the body's actual distribution of mass, if the total mass of the body were concentrated there. The dimension of Radius of Gyration is same as distance which is [L ...
5. Robert Gilmour LeTourneau (November 30, 1888 – June 1, 1969), born in Richford, Vermont, was a prolific inventor of earthmoving machinery, and founder of LeTourneau Technologies, Inc [1] and LeTourneau University. His factories supplied machinery which represented nearly 70 percent of the earthmoving equipment and engineering vehicles used ...
Game mechanics. In tabletop games and video games, game mechanics are the rules or ludemes that govern and guide the player's actions, as well as the game's response to them. A rule is an instruction on how to play, a ludeme is an element of play like the L-shaped move of the knight in chess. A game's mechanics thus effectively specify how the ...
George R. Irwin was born in El Paso, Texas. His family moved to Springfield, Illinois where he went to school. He attended Knox College in Galesburg, Illinois and earned an A.B. degree in English in 1930. After an additional year studying physics, he transferred to the University of Illinois at Urbana-Champaign where he studied from 1931 to 1935.
Mechanics (from Ancient Greek: μηχανική, mēkhanikḗ, lit. "of machines ") [1] [2] is the area of physics concerned with the relationships between force, matter, and motion among physical objects. [3] Forces applied to objects result in displacements, which are changes of an object's position relative to its environment.
Functional renormalization group. In theoretical physics, functional renormalization group ( FRG) is an implementation of the renormalization group (RG) concept which is used in quantum and statistical field theory, especially when dealing with strongly interacting systems. The method combines functional methods of quantum field theory with the ...
