    en.wikipedia.org/wiki/Joule

    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 ).

    en.wikipedia.org/wiki/Term_symbol

    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.

    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:
