The International System of Units—a case for reconsideration

The International System of Units (SI) follows a concept that goes back to Maxwell. At that time, a logic sound foundation of mathematics was not yet available. This has lead to concepts and terms that are contradictory and in conflict with today’s standard mathematical concepts. The inconsistencies that have evolved in metrology due to the lack of appropriate notions are pointed...

Integer numbers and their ratios are key concepts in describing the interactions of atoms and molecules

A general discussion of the redefinition of the mole, the SI unit for ‘amount of substance’, is now ongoing in ever broadening circles as part of a general overhaul of the Système International d’Unités, SI. Important for chemists are the unit mole (symbol mol) and the unit kilogram (symbol kg).For several thousands of years, ‘mass’ was the property enabling measurement of “how...

Fuzzy logic-based procedures for GMO analysis

Key to sound validation studies is the formalization and harmonization of procedures for design of experiment and interpretation of results. International guidelines (ISO 5725, ENGL) are available for the validation of GMO detection methods, and ad-hoc validation statistics (e.g. per cent bias, repeatability and reproducibility) are used for in-house and inter-laboratory testing...

An Editor shall not “censor” submitted papers

This issue of ACQUAL contains a paper which is certainly “unconventional”: it is critical about a ‘Convention’.Or, better, it is critical about the effects of a Convention.It critically examines the value of the ‘Convention du Mètre’ (the Intergovernmental Treaty on the Metre, 1875) with respect to chemical measurement.It was providing the occasion for the Editors to examine a...
