Primera álgebra de magnitudes

Book Description
E-mail: [email protected] Las ecuaciones de la Física no relacionan sin más números, vectores o tensores de índole matemática, sino cantidades diádicas formadas con esos componentes vinculados a unidades diversas que indican cantidades de magnitudes naturales. Entonces, ¿por qué se opera con los entes diádicos de la Física como si fuesen elementos matemáticos puros?, ¿no supone esta ficción una aberración que envilece todo el conocimiento científico? Algunos autores han advertido de esta laguna crítica, que oculta a la Física un pilar tan fundamental. Pueden citarse preeminentes físicos como Clerk Maxwell o Max Planck, entre otros clásicos. Todos manifestaron a su manera los escrúpulos suscitados por la tradicional e injustificada forma de operar con las magnitudes físicas y sus unidades. Aquí se descubre, describe y resuelve tan notable paradoja de «aritmetización» de la Física y se construye un álgebra rigurosa y coherente para las cantidades de magnitudes. La Primera álgebra de magnitudes resuelve la hipótesis falsa del Sistema Internacional de Unidades, consistente en suponer negligentemente que las magnitudes físicas presenten estructura multiplicativa de grupo abeliano. No puede ser así, como se demuestra en este trabajo. Finalmente, se pone de manifiesto el camino lógico e inapelable que conduce del álgebra de magnitudes a los espacios «dismétricos», que se estudian con mayor profundidad en el segundo volumen de esta obra. La «dismetría» es una nueva y poderosa herramienta para representar con precisión los fenómenos físicos de un universo variable. Esta nueva Física acoge multitud de innovaciones, que sin duda sabrán apreciar muchos investigadores emprendedores. The equations of Physics do not simply relate numbers, vectors or tensors of a mathematical nature, but rather dyadic quantities formed with these components linked to various units that indicate quantities of natural magnitudes. So, why do we operate with the dyadic entities of Physics as if they were pure mathematical elements? Doesn't this fiction suppose an aberration that debases all scientific knowledge? Some authors have warned of this critical gap, which hides such a fundamental pillar from Physics. Pre-eminent physicists such as Clerk Maxwell or Max Planck, among other classics, can be cited. All of them expressed in their own way the scruples aroused by the traditional and unjustified way of operating with physical quantities and their units. Here such a remarkable «arithmeticization» paradox of Physics is discovered, described and solved and a rigorous and coherent algebra is constructed for the quantities of magnitudes. The First Algebra of Magnitudes resolves the false hypothesis of the International System of Units, consisting of negligently assuming that physical magnitudes have a multiplicative abelian group structure. It cannot be like that, as demonstrated in this work. Finally, the logical and unappealable path that leads from the algebra of magnitudes to the «dysmetric» spaces is revealed, which are studied in greater depth in the second volume of this work. «Dysmetry» is a powerful new tool for accurately representing the physical phenomena of a variable universe. This new Physics welcomes a multitude of innovations, which will undoubtedly be appreciated by many enterprising researchers.
