2Null dust solution — In mathematical physics, a null dust solution (sometimes called a null fluid) is a Lorentzian manifold in which the Einstein tensor is null. Such a spacetime can be interpreted as an exact solution of Einstein s field equation, in which the only… …
3Null modem — A null modem adapter Null modem is a communication method to connect two DTEs (computer, terminal, printer etc.) directly using an RS 232 serial cable. The name stems from the historical use of the RS 232 cable to connect two teleprinter devices… …
4Null hypothesis — For the periodical, see Null Hypothesis: The Journal of Unlikely Science. The practice of science involves formulating and testing hypotheses, assertions that are capable of being proven false using a test of observed data. The null hypothesis… …
5Null corrector — Testing a spherical mirror using an interferometer. All surfaces in the tester are either flat or spherical, so the tester itself is fairly easy to fabricate and test. This setup can test a spherical mirror of any size since the wavefront is… …
6Electrovacuum solution — In general relativity, an electrovacuum solution (electrovacuum) is an exact solution of the Einstein field equation in which the only nongravitational mass energy present is the field energy of an electromagnetic field, which must satisfy the… …
7Michell solution — The Michell solution is a general solution to the elasticity equations in polar coordinates ( ). The solution is such that the stress components are in the form of a Fourier series in . Michell[1] showed that the general solution can be expressed …
8Monochromatic electromagnetic plane wave — In general relativity, the monochromatic electromagnetic plane wave spacetime is the analog of the monochromatic plane waves known from Maxwell s theory. The precise definition of the solution is a bit complicated, but very instructive. Any exact …
9Gödel metric — The Gödel metric is an exact solution of the Einstein field equations in which the stress energy tensor contains two terms, the first representing the matter density of a homogeneous distribution of swirling dust particles, and the second… …
10Kernel (matrix) — In linear algebra, the kernel or null space (also nullspace) of a matrix A is the set of all vectors x for which Ax = 0. The kernel of a matrix with n columns is a linear subspace of n dimensional Euclidean space.[1] The dimension… …
