Did You Know?

Many of us often use precision and accuracy as synonyms, but not scientists and engineers. For them, accuracy describes a particular measurement—that is, how close it is to the truth. But precision describes a measurement system—that is, how good it is at giving the same result every time it measures the same thing. This may be why even nonscientists now often speak of "precision instruments" for measuring, "precision landings" made by airplanes, "precision drilling" for natural gas, and so on.
