| i wonder if interest in measuring error of previous calculations is what encouraged this direction of computational rigor respecting accuracy encourages a self awareness with an almost conscious stead ignorant error i am always intrigued when it is discussed how a calculation began and the error of the initial values the first known attempt at measuring the speed of light(o) had an ignorant error of ~26% the first known attempt at measuring the circumference of the earth(i) had an ignorant error of ~15% > our planet Earth.. the circumference ..

our conscious error is the size of a molecule, but what will our ignorant error be? how will its significance manifest?the ignorant error is a result of the tools of measure, in this case observable measurements and numerical approximation for those who calculated using pi equal to 22/7, for the circumference, their error would only be ~.04% of the 15 digit rounded value >>>2*(22/7)*(7926/2)>>> 2*(22/7)*(7926/2)
