Christianities in the Trans-Atlantic World Geometry are described. But how these geometries look like? In this chapter we present an algebraic model for Euclidean Geometry discussing some important theorems. We obtain a visual representation for the Euclidean Geometry of the plane.抛弃的货物 发表于 2025-3-27 02:43:23
The Social Function of American Creationism,tions of the Euclidean plane, the geometric inversion. We still need some other acquirements, therefore we meet the Projective Geometry. An invariant described by a special projective map of a circle allows us to construct a non-Euclidean distance inside the disk. Elaborating the previous model we highlight the Poincaré disk model.五行打油诗 发表于 2025-3-27 08:06:39

The substance of the General Relativity is related to the invariance under changes of coordinates and to the tensor structure of objects that have to present the same form in any reference frame. These two main properties can be related to the deep meaning of General Relativity which has the Equivalence Principle as the physical starting point.CODE 发表于 2025-3-27 20:15:04
