ASTUTE READER NOTICES: CONVERSION OF RCF TO RPM IS UNCLEAR

Hi Dany Spencer Adams, I think there might be an error in the equation for converting RCF to rpm on page 140 of the second edition, hardcover. Should the equation be: rpm= (RCF / (r x 1.118 x 10^-6))^1/2 instead of 10^-5? because the radius is measured in mm? … E. D. Dear E. D. [...]

This blog, like the book Lab Math from which it springs (incompletely formed), will be about numbers. I will endeavor to:

1. showcase the basic and the practical, not the challenging or even the advanced;

2. provide straightforward guidance for the unenthusiastic ("just do it exactly this way");

3. provide refreshers for those needing refreshment (whether they know it or not.)
