Molten rock in the earth's crust
Magma (from Greek u03BCu03ACu03B3u03BCu03B1, "thick unguent") is a mixture of molten or semi-molten rock, volatiles and solids that is found beneath the surface of the Earth, and is expected to exist on other terrestrial planets and some natural satellites. Besides molten rock, magma may also contain suspended crystals, dissolved gas and sometimes gas bubbles...
Magma is a computer algebra system designed to solve problems in algebra, number theory, geometry and combinatorics. It is named after the algebraic structure magma. It runs on Unix-like and Linux based operating systems, as well as Windows.
Magma is molten rock found under the Earth's surface.
In abstract algebra, a magma (or groupoid; not to be confused with groupoids in category theory) is a basic kind of algebraic structure. Specifically, a magma consists of a set, M, equipped with a single binary operation, M u00D7 M u2192 M. The binary operation must be closed by definition but no other properties are imposed.
