In reply to Hoyt A. Stearns Jr.'s message of Fri, 20 Apr 2012 19:09:27 -0700: Hi, [snip] >Only three values are needed to perform all calculations: c, the Rydberg >frequency, and Avagadro's number.
Almost any three natural constants are enough to derive all the rest. This is well known in physics. However Avogadro's number is not a natural constant, because it's based upon our definition of the gram, which is arbitrary. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
