Avogadro Number, Boltzmann Constant, Planck Constant, Information Theory, Comparative and Relative Uncertainties
American Journal of Computational and Applied Mathematics 2018, 8(5): 93-102 DOI: 10.5923/j.ajcam.20180805.02 h, k, NA: Evaluating the Relative Uncertainty of Measurement Boris Menin Mechanical & Refrigeration Consultation Expert, Beer-Sheba, Israel Abstract For verification of the measurement accuracy of fundamental physical constants, the CODATA unique technique is used. This procedure is a complex process based on a careful discussion of the input data, and the justification and construction of tables of values sufficient for the direct use of the relative uncertainty are conducted using modern advanced statistical methods and powerful computers. However, at every stage of data processing, researchers must rely on common sense, that is, an expert conclusion. In this article, the author proposes a theoretical and informational grounded justification for calculating the relative uncertainty by using the comparative uncertainty. A detailed description of the data and the processing procedures do not require considerable time. Examples of measurements results of three fundamental constants are analysed, applying information-oriented approach. Comparison of the achieved relative and comparative uncertainties is introduced and discussed. Keywords Avogadro number, Boltzmann constant, Planck constant, Information theory, Comparative and relative uncertainties theories of physics can be proved by carefully studying the 1. Introduction numerical values of these constants, determined from different experiments in different fields of physics. It is expected that in 2018 that the International System of One needs to note the main feature of the CODATA Units (SI) will be redefined on the basis of certain values of technique in determining the relative uncertainty of one some fundamental constants [1].
