This paper discusses some topics that stem from recent contributions made by the History, the Philosophy, and the Didactics of Science. We consider these topics relevant to the introduction of the Special Relativity Theory ...

We give two examples of algebraic sequences arising from modular forms which are good approximations for ζ(3) and the hybrid constant 8C+(π2/√2) where C=σ∞ 0 (-1)n/(2n+1)2 is Catalan's constant.

In this work, we design, implement and analyze a didactic sequence for the teaching of the basic topics of special relativity theory in high school. The sequence proposes a series of situations, specially designed to allow ...

We have divided this review into two major sections. In one, we have attempted to present an overview of our current understanding of prokaryotic insertion sequences (IS), their diversity in sequence, in organization and ...

El presente trabajo trata de dar un panorama general de los aspectos relevantes que tienen las MPyMES como impulsoras de la economía mexicana. Pero principalmente, expone los aspectos que debe considerar quien quiere ...

The number and diversity of known prokaryotic insertion sequences (IS) have increased enormously since their discovery in the late 1960s. At present the sequences of more than 4000 different IS have been deposited in the ...
