Physicists like numbers. We measure them, calculate them and use them to test experiment against theory.

Yet we also respect numbers. We appreciate their limitations and we take extreme care to educate students that numbers are open to misinterpretation. From the first years of university-level physics teaching we stress how measurements are affected by systematic and random errors and uncertainties, and we explain and distinguish the difference between accuracy (“truth”) and precision (“reproducibility”)…
