How do we ensure that the values we measure are accurate and precise?
Accuracy refers to how close a measurement is to the true value. Precision refers to how close repeated measurements are to each other. Both accuracy and precision are essential for reliable scientific research.
Imagine you’re weighing a bag of sugar on a kitchen scale. The scale might be accurate, meaning it shows the correct weight on average. But if it’s not precise, it might give you different readings every time you weigh the bag. This would make it difficult to determine the exact weight of the sugar.
The same principle applies to measuring constants. We need to be confident that our measurements are both accurate and precise. This means using reliable instruments, following standardized protocols, and minimizing sources of error.
For example, the speed of light is one of the most important constants in physics. It has been measured countless times with ever-increasing accuracy. But even the most precise measurements have some degree of uncertainty. This uncertainty is due to factors such as the limitations of our instruments and the unpredictable nature of the universe itself.
