How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Data: 16 decembrie 2021 Autor: Abel Cavași Despre nedeterminare Încă din gimnaziu elevii învață să evite fracțiile care au numitorul nul, deoarece un număr împărțit cu zero dă un rezultat neclar. Mai exact, știm că , 5 1 = 5 , 5 0,1 = 50 00, 5 0,01 = 5 , 5 0,001 = 5000 și așa mai departe. Altfel spus, cu cât îl împărțim pe 5 la un număr din ce în c...
If a moving planet has a trajectory whose curvature can be easily determined, then at rest the curvature can no longer be determined, being nonsense. Nature cannot accept the transition from a well-determined to an indeterminate curve. As this applies to any observer in the Universe, it means that the true velocities of bodies are, in fact, equal t...
About generalizing Einstein's principle of equivalence and the consequences of this generalization for the study of black holes.
Starting from the invaluable mathematical conclusion according to which the torsion of a straight line is undefined and knowing that the rectilinear motion implies moving on a straight line, we can conclude that a rectilinear motion results in an undefined torsion of line. Thus, the information about torsion is not preserved in physical interaction...
In this paper we generalize Frenet trihedron and we provide some other classes of trihedrons, called Frenet trihedrons of order n, n ≥ 1. Moreover we prove that those trihedrons can be defined recurrently and we emphasize their role in the study of the generalized helices of order n. As practical applications we present the influence of the recurre...
