Experimentally obtaining metrics in general relativity
A F F Teixeira
It seems to be not well known that the metrics of general relativity (GR) can be obtained without integrating Einstein equations. To that, we need only define a unit for GR-interva…
Taub, Rindler, and the static plate
A F F Teixeira
An infinite 3D plate of homogeneous incompressible fluid is considered, with finite thickness, together with a 2D infinite homogeneous mass in its centre. Einstein equations are ex…
Angula distanco en kaloto
A F F Teixeira
A cap in a 2-D sphere is considered, smaller than an hemisphere. Two points are randomly chosen in the cap. The probability density that the angular separation between the points h…
Separations inside a cube
A. F. F. Teixeira
Two points are randomly selected inside a three-dimensional euclidian cube. The value l of their separation lies somewhere between zero and the length of a diagonal of the cube. Th…
Distances in plane membranes
A. F. F. Teixeira
A flat membrane with given shape is displayed; two points in the membrane are randomly selected; the probability that the separation between the points have a specified value is so…
Cosmic crystallography: the hyperbolic isometries
A. F. F. Teixeira
All orientation preserving isometries of the hyperbolic three-space are studied, and the probability density of conjugate pair separations for each isometry is presented. The study…
