geometry
That part of mathematics concerning itself with surfaces or more general spaces as well as objects defined on such spaces, such as points or lines as well as the objects constructable from points and lines, such as ...
geodetic precession
In classical mechanics, the rotation axis of a gyroscope on which no external forces are acting will remain constant - a useful property that has found applications in navigation. However, in the presence of spacetime curvature, this is no longer true - the ...
geodesic
A straightest-possible line in a surface or a more general space. In the plane, the geodesics are straight lines, on the surface of a sphere they are great ...
GEO600
British-German gravitational wave detector located in Ruthe (close to Hannover, Germany). GEO600 is an interferometric gravitational wave detector with an arm-length of 600 metres. GEO600 ...
general theory of relativity
Albert Einstein's theory of gravity; a generalization of his special theory of relativity. For information about the concepts and applications of this theory, we recommend the chapter general relativity of our introductory section Elementary Einstein. ...
gas
In a strict sense: A state of matter in which the atoms and/or molecules wildly careen and collide, without being bound to each other. This movement leads to an inner pressure, while the average kinetic energy of the moving particles is a measure for the ...
gamma rays
The most highly energetic variety of electromagnetic radiation , with over a quintillion oscillations per second, corresponding to wave-lengths of less than a hundredth billionth of a ...
