Data Sheets are written by engineers for engineers.
I stated that above.
Well, today I glanced through one of my german books: "Applied Mathematics for Photographers and Photo Lab Technicians" 3.ed, 1971
On its densly printed 200 pages it covers stoichiometry and mixing equations, calculations based on the lens formula, calculation of wages, expenses and profits. But no word about logarithms...
The understanding of logarithms, among other things as indicated above, is a prerequisite of understanding data Sheets.
