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.
Molality is the number of moles of solute per kilogram of solvent. It is abbreviated with the symbol m (lowercase), and is sometimes used as a unit of measurement, e.g. a 0.3 molal solution of HBr. In that example, there would be 0.3 moles of HBr for every kilogram of water (or whatever the solvent was).
