Moyal bracket. In physics, the Moyal bracket is the suitably normalized antisymmetrization of the phase-space star product. The Moyal Bracket was developed in about 1940 by JosÃ© Enrique Moyal, but Moyal only succeeded in publishing his work in 1949 after a lengthy dispute with Paul Dirac.
From Wikipedia, the free encyclopedia. For other uses, see Muscovite (disambiguation) . Muscovite (also known as common mica, isinglass, or potash mica) is a phyllosilicate mineral of aluminium and potassium with formula K Al 2 (Al Si 3 O 10)(F ,O H) 2, or (KF) 2 (Al2O3) 3 (SiO2) 6 (H2O).It has a highly perfect basal cleavage yielding remarkably thin laminae (laminÃ¦) sheets which are often highly. elasticuscovite has a Mohs hardness of 2â2.25 parallel to the [001] face, 4 perpendicular to the [001] and a specific gravity of 2.76â3. It can be colorless or tinted through grays, browns, greens, yellows, or (rarely) violet or red, and can be transparent or translucent.
