- + Issue 935: (16) Annex D -Discipline and Constants file corrections:

[Jon Sanders, 1/22/2001]

  (16) Annex D -Discipline and Constants file corrections:
  
   In review of the disciplines.vams file, the following were observed for discussion and correction. Are these suppose to be
   based on SI? how do we deal with those without SI units?
    
  
  The units "coul" should be "C" for nature Charge. This is the standard SI symbol. Of course, that could confuse some folks with temperature would be "degC".
  
    
  
  The unit on Angle would be "rad" to be SI compliant. And "rad/s" for Angular_Velocity and "rad/s^2" for Angular_Acceleration. Each of these put an "s" at the end of rad.
  
    
  
  The physical constants should be listed with a reference. What is the source of these values? The 1998 NIST values differ from those given for physical constants:
  
    
     charge: 1.602176462e-19
     light: 2.99792458e-8
     boltzmann: 1.3806503e-23
     planck: 6.62606876e-34
     ...etc...
     Source:physics.nist.gov/cuu/Constants/index.html
    
  
  Both Boltzmann and Planck are misspelled in the constants file.
  
      
     Recommendation: Consider the above changes
