Suppose I am working on a problem and I wish to calculate the density of something. I measure the mass to be m = 24.5 grams and the volume is V = 10 cm 3. In this case the density would be: ALERT!

Measurement uncertainty, as described in ISO/IEC Guide 98, is a “parameter, associated with the result of a measurement, [which] characterizes the dispersion of values that could reasonably be ...

Students distinguish between accuracy and precision of measurements. Accuracy, Precision, and Significant Digits: Students distinguish between accuracy and precision of measurements and make ...

The rules of statistical physics address the uncertainty about the state of a system that arises when that system interacts with its environment. But they've long missed another kind. In a new paper, ...
