comment Is a “shift in the meaning” of Accuracy and Precision occurring?
@DavidHammen ....................................................... It's true that the BIPM wanted "(a)" and "(b)", but the question is "Is shift in meaning really occurring in the physics/measurement community at large?" . Answer is No, shift in meaning is not really occuring in the "measurement community" at large, since "measurement community" means the whole world. (tiar)

@Self-MadeMan, I mean self-learning, not paid-learning.

@DavidHammen, That's ok, but your comment proves that my answer is correct. As I've mentioned, metrology (science of measurement) is not the only field doing measuring. Everyone is doing measurements and the concepts of systematic and random error do not only exist within metrology; they have been addressed in other fields as well.....................................

comment Is a superconductor really a super conductor?
@anna, I mean did we actually observed 0.0000000... up to like 200 decimal places? Because if we did, we can say it's practically zero. Or did we actually observed data for only ~10 decimal places?

comment Is a superconductor really a super conductor?
@anna, When you say "epsilon delta relationship", do you mean "yes, exactly 0.000000000 resistance is possible" or do you mean "no, we can never get exactly 0.000000000 resistance"?
