In that way defined geometrical structure of spacetime is substantial, because it is invariant as a pseudo-Riemannian space with affine relationship all physical events are accidental and fully reducible to the manifestations of the substratum i.
The Euclidean space and Minkowski's space are the intermediate structures between fundamental mathematical structure complex space of spinors and physical spacetime.
Theories of spacetime in mathematical physics, while considering continua and metric manifolds, cannot explain the difference between time dimension and space dimensions, they are also unable to explain by means of geometry the unidirection of the passage of time, which can be comprehended only by means of thermodynamics.
Metricstructure includes metre, tempo, and all rhythmic aspects which produce temporal regularity or structure, against which the foreground details or durational patterns are projected (Wittlich 1975, chap.
The beat level is the metric level at which pulses are heard as the basic time unit of the piece.
A metric modulation is a modulation from one metric unit or metre to another.
