Precision and Accuracy are important concepts in measurement science, and are key concepts in Applied Physics. They don not mean the same thing. A measurement is precise when the value is highly reproducible. An accurate measurement returns values that are close to the expected real value. Ideally one wants both qualities.
The drawing is a playful depiction of the concept, with circles of a variety of sizes and qualities arrayed near the center of the drawing (some accuracy, but low precision). These contrast with clusters of more similar and closely spaced circles located off-center (some precision, low accuracy). There are also a few that are precise enough to be concentric, and are accurate enough to be close to the center.
Aside from the cheeky depiction of the concept, the drawing expresses a feature of all of the pieces in my Idea Cycles series, the interplay of freehand drawing versus compass, ruler and template assisted figures. The manner in which these features...
