I find great comfort in the logic of mathematics.
I have had to abandon the use of “math” recently after hearing people who know absolutely as little mathematics as humanly possible say, “Do the math,” when it’s simple arithmetic.
There is a branch of mathematics that abhorred in high school (and carried over into college). It is statistics. With only a slide rule and no calculator [I am 72 years old.], it was extremely tedious to calculate standard deviations from even a small data set.
Being assigned to my work’s corporate initiative to embrace Six Sigma company wide. I got another chance at statistics. This time with computer assistance. Standard deviations were nearly instantly calculated. I now strongly embrace statistics. It lacks the precision answers of the mathematics that I grew up loving, so I was a slow sale, but I finally got there.
Even in statistics there is “certainty” within the variation. With a good grounding in statistics you can take your body weight every day (best done same time of day every day, upon waking being best) and not be alarmed from day to day when variation of your weight appears. Don’t worry about the “noise”, look for the “signal.”
