61Isometric projection — is a form of graphical projection more specifically, an axonometric projection. It is a method of visually representing three dimensional objects in two dimensions, in which the three coordinate axes appear equally foreshortened and the angles… …

65Frame fields in general relativity — In general relativity, a frame field (also called a tetrad or vierbein) is a set of four orthonormal vector fields, one timelike and three spacelike, defined on a Lorentzian manifold that is physically interpreted as a model of spacetime. The… …
66Gravitational lensing formalism — In general relativity, a point mass deflects a light ray with impact parameter b by an angle hat{alpha} = frac{4GM}{c^2b}. A naïve application of Newtonian gravity can yield exactly half this value, where the light ray is assumed as a massed… …

68Roman surface — The Roman surface (so called because Jakob Steiner was in Rome when he thought of it) is a self intersecting mapping of the real projective plane into three dimensional space, with an unusually high degree of symmetry. The mapping is not an… …
