The setting on the Rigormeter (TM) determines the level of mathematical
rigor that will prevail in a math class on any given day. Guidelines
are roughly as follows:
0 = Unjustifed claims, proofs by assertion or intimidation.
2 = Reform calculus text.
5 = Typical junior or senior level math course.
10 = Real Analysis. Also includes Number Theory when taught by Rickert.
