The reduced Planck constant is known by many other names: the rationalized Planck constant: 726 : 10 : - (or rationalized Planck's constant: 334 : ix : 112 ), the Dirac constant: 275 : 726 : xv (or Dirac's constant: 148 : 604 : 313 ), the Dirac : xviii (or Dirac's : 17 ), the Dirac : 187 (or Dirac's : 273 : 14 ), and h-bar.

La costante di Planck, indicata con , è una costante fisica fondamentale della meccanica quantistica, introdotta come la costante di proporzionalità fra l' energia e la frequenza di un fotone nei primi anni del novecento da Max Planck e Albert Einstein, rispettivamente nello studio della radiazione emessa da un corpo nero e dell' effetto fotoele...
Also, c is the speed of light, and ħ is the reduced Planck constant. These fundamental physical constants reflect special relativity and quantum mechanics, respectively. Dirac's purpose in casting this equation was to explain the behavior of the relativistically moving electron, and so to allow the atom to be treated in a manner ...
H-bar or h-bar can refer to: H with stroke, a Latin letter H with a doubled horizontal stroke ( Ħ ħ ) Voiceless pharyngeal fricative, represented in IPA by ħ . Reduced Planck constant, in which the above symbol represents as a mathematical symbol, ħ = h / (2 π) Antihydrogen, an antimatter element represented by the symbol. H.
is the Planck constant, and; is the speed of light in vacuum. The symbol means that the nucleus is assumed to be infinitely heavy, an improvement of the value can be made using the reduced mass of the atom: = +
where = is the reduced Planck constant. The quintessentially quantum mechanical uncertainty principle comes in many forms other than position–momentum. The energy–time relationship is widely used to relate quantum state lifetime to measured energy widths but its formal derivation is fraught with confusing issues about the nature ...
G, the gravitational constant, ħ, the reduced Planck constant, and; k B, the Boltzmann constant. Variants of the basic idea of Planck units exist, such as alternate choices of normalization that give other numeric values to one or more of the four constants above.
