Re: Which program do you use the most Message #2 Posted by Ed Look on 30 Sept 2011, 3:36 p.m., in response to message #1 by David Persinger (US)
I do research in and teach chemistry and physics; I got tired of converting from eV to nm or Å, and so I just wrote a short routine to do this for me. Also, HP calculator constant libraries generally list R, the gas constant in the proper, SI term of joules; and since I often need the ancient, but still oft-used l-atm, there's a little program for that. And then, there's a suite of four that I use often for calculating average, median, mode, maximum, and minimum of a set of data. The mode program is, I guess in today's terminology, still under construction; maybe I'll try to fix it one of these nights now that baseball season is over (although it's been several baseball seasons now!)
Other ones:
one to calculate the Miller Indices (in the Museum program archives!) of planes in cubic crystals from their 2-theta reflections (not for me myself, but I use it generally to make sure students don't pull a fast one). This one took a while to complete (and cubic is EASY); I'm not sure I want to contemplate routines for less symmetric unit cells.
