### Summary

The subject follows the basic experience gained in the Introduction to laboratory exercises and extends them mainly in the theoretical field. Syllabus of the course: 1. Theory of Physical Measurement: Reproducibility of measurement results as the basis of the scientific method. Measurement as a benchmarking process. Measurement units - a system of SI units. Calibration and certification 2. Measurement uncertainty: Result of measurement, reality and measurement error. Uncertainty of measurement result. Statistical standard uncertainty (type A). Systematic standard uncertainty (type B). Combined standard uncertainty. Extended uncertainty increases the reliability of the measurement result. The Covarian Law and the Gauss Law to spread uncertainty in indirect measurement. Band of uncertainties of functional dependence. Rounding and numerical formulation of the measurement result. Gross error and reliability of measurement results. 3. Direct measurements of physical quantities: Measurement of length. Angle measurement. Volume measurement. Measuring time. Weight measurement. Temperature measurement. Pressure measurement. Electrical voltage measurement. 4. Experiment scheme: Experiment design. General formats of physical dependence graphs. Realization of the experiment. Recording of the results of the direct measurements - data table format. Evaluation and physical analysis of the experiment result. Publication of experiment results (sample laboratory protocol). Sample of the laboratory protocol.
