Bernulf Kanitscheider on Measurements - Dictionary of Arguments
I 220 Def Measure/Def Define/Kanitscheider: measuring is an empirical process supported by theories, while defining is a conceptual activity carried out within the framework of a theory. The meaning of a theoretical term can only be elucidated by semantic investigation. Measurement assigns numerical values to already metrized quantities with factual reference represented by a particular function. >Operationalism/Kanitscheider. I 229 Measurement/Kanitscheider: Problem: all astronomical distance determinations have always only certain range. So one must work with overlapping measuring chains. "Homogeneity extrapolation: e.g. period luminosity relation of Cepheids, diameter luminosity relation of H II regions and constancy of luminosity of Sc I galaxies. Bsp These models carry into the determination of H0 (age of the universe) a hypothetical element, which one can justify if not empirically, nevertheless rationally. Similarly: Ex Determination of today's acceleration parameter q0 (or brake parameter): is mostly tried to be determined from the dependence between the apparent brightness and the redshift of the galaxies. Problem: to find an object of known standard magnitude at a sufficient distance. Method: to pick the brightest galaxy in a known regular cluster of elliptical galaxies as a "standard candle". But again, the assumption is that the galaxies retain their luminosity over a long time._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
