Cross product "matrix", then it can be generalized in an arbitrary number of dimensions. In mechanics, for example, the angular velocity can be interpreted either as a pseudovector formula_167 or as a anti-symmetric matrix or skew-symmetric tensor formula_168. In the latter case, the velocity law for a rigid body looks: where Ω is formally defined from the rotation matrix formula_170 associated to body's frame: formula_171 In three-dimensions holds: In quantum mechanics the angular momentum formula_173 is often represented as an anti-symmetric matrix or tensor. More precisely, it is the result of cross product involving position formula_174 and linear momentum formula_111: Since both
Canon of the Mass in all liturgical texts. Fortescue remarked that the medieval explanations are interesting as showing with what reverence people studied the text of the Canon and how, when every one had forgotten the original reasons for its forms, they still kept the conviction that the Mass is full of venerable mysteries and that all its clauses mean more than common expressions. He added that in this conviction the sometimes naive medieval interpreters were eminently right. Canon of the Mass Canon of the Mass (Latin: "Canon Missæ", "Canon Actionis") is the name given in the Roman Missal, from the first typical edition
