Symbol Meaning SI unit of measure magnetic vector potential: tesla meter (T⋅m) : area: square meter (m 2) : amplitude: meter: atomic mass number: unitless acceleration: meter per second squared (m/s 2)
This is the definition declared in the modern International System of Units in 1960. [ 13 ] The definition of the joule as J = kg⋅m 2 ⋅s −2 has remained unchanged since 1946, but the joule as a derived unit has inherited changes in the definitions of the second (in 1960 and 1967), the metre (in 1983) and the kilogram ( in 2019 ).
In atomic physics, a term symbol is an abbreviated description of the total spin and orbital angular momentum quantum numbers of the electrons in a multi-electron atom.So while the word symbol suggests otherwise, it represents an actual value of a physical quantity.
Behavioral momentum is a theory in quantitative analysis of behavior and is a behavioral metaphor based on physical momentum.It describes the general relation between resistance to change (persistence of behavior) and the rate of reinforcement obtained in a given situation.
where A is an antisymmetric matrix, ψ is a collection of Grassmann variables, and the 1 / 2 is to prevent double-counting (since ψ i ψ j = −ψ j ψ i). In matrix notation, where ψ and η are Grassmann-valued row vectors, η and ψ are Grassmann-valued column vectors, and M is a real-valued matrix:
Mathematical psychology is an approach to psychological research that is based on mathematical modeling of perceptual, thought, cognitive and motor processes, and on the establishment of law-like rules that relate quantifiable stimulus characteristics with quantifiable behavior (in practice often constituted by task performance).
