Laws/physics/scalar quantities/scalar/temperature/Field: physical laws for scalar variables are often formulated as laws on a scalar T, that maps the quadruple of real numbers (space-time localization) to real numbers (e.g. temperature).
Function T: (scalar) then has the form T = y Â ° φ-1. several space points mapped to a point on the scale.
φ -1: inverse of the function: (archetype instead of image): because it is processed twice: the second time backwards).
φ (x): x coordinates of in space
φ -1 (x): images of the coordinates on the line R)._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number. The corresponding books are indicated on the right hand side. ((s)…): Comment by the sender of the contribution.
