The attitudes and beliefs of teachers and future physics teachers about epistemological aspects of Physics play a very important role in teaching the discipline. In this paper, after describing some of the most important results reported in the literature, we present the main results of the implementation of the CLASS test on attitudes and beliefs to hundreds of student and physics teacher in Uruguay. The results corresponding to the teaching students are similar to those who choose careers with an emphasis on Physics and Mathematics and, in turn, are clearly below those presented by professors and researchers. We highlight then the need to make explicit the issues related to epistemological attitudes and beliefs in our classes.
Being aware of the motivation problems observed in many scientific oriented careers, we present two experiences to expose to college students to environments, methodologies and discovery techniques addressing contemporary problems. This experiences a
Here we show the preliminary results of a photometric study of low surface brightness objects with $mu_{g}~gtrsim~25$~mag/arcsec$^2$. These objects are present in several fields obtained with GEMINI-GMOS, in the central region of the Pegasus I group.
A modification to the gnomonic factor using the concept of triangle of Plato is presented. With the aid of the platonic gnomonic factor (fgp) as we called it, we find that the oracles mentioned by Herodotus in his History, Dodona in Greece and Ammon
We correct an error that occurs with certain frequency in popular literature of Special Relativity, namely that supposedly that mass of moving objects depends on the relative velocity of the object and the observer. In this pedagogical paper, we expl
Here we show the preliminary results of a study where there seems to be a bias effect in the size distributions of the detected low-surface brightness (LSB) galaxies in different environments. In this sense, more distant groups/clusters would lack sm
