Amount of Information and Measurement Uncertainty

Aims: To acquaint specialists in the field of physics and technology, experimenters and theoreticians with the possibilities of using information theory to analyze the results of an experiment, without a statistical and subjective expert approach.

Place and Duration of Study: Mechanical & Refrigeration Consultation Expert, between December 2019 and February 2020.

Methodology: Using the information approach and calculating the amount of information contained in the model of measuring a physical constant, we formulate a quantitative indicator for analyzing the results of the experiment.

Results: The appropriateness of applying the described approach is checked when studying the database when measuring various physical constants. The approach is applicable to the analysis of results obtained both for a long and a short period of time.

Conclusion: The information-theoretical approach allows us to formulate a universal indicator of the threshold mismatch between the model and the phenomenon, applicable to all scientific and technical fields in which the International System of Units (SI) is used.
