  dcterms:description """
  The $\\textit{Reduced Planck Constant}$, or $\\textit{Dirac Constant}$, is used in applications where
   frequency is expressed in terms of radians per second ($\\textit{angular frequency}$) instead of cycles per second. 
  In such cases a factor of $\\pi$ is absorbed into the constant.
