What is the role of precision in physics and how does it impact the accuracy of experimental measurements?
Precision in physics refers to the level of detail and exactness in measurements. It is crucial in experimental measurements as it determines the consistency and reproducibility of results. A high level of precision ensures that measurements are reliable and can be compared accurately. However, precision alone does not guarantee accuracy. Accuracy, on the other hand, refers to how close a measurement is to the true value. Even with high precision, experimental measurements can still be inaccurate if there are systematic errors or biases present in the measurement process. Therefore, precision and accuracy are both important factors to consider in experimental physics to ensure the validity of results.

Did experimental physics or the theoretical physics come first?
Experimental physics. Only with experiments come a theory:)
What is limit of accuracy?
The limit of accuracy refers to the point at which increasing the precision or detail of a measurement or calculation no longer produces significantly more accurate results. This limit is determined by factors such as equipment capabilities, inherent uncertainties in measurements, and the laws of physics governing the system being studied. Exceeding this limit may result in diminishing returns or increased error.
