Presentation Text in English (written by the author): Master in Teaching of Mathematics and Sciences - Area of concentration: Teaching of Physics - by the Pontifical Catholic University of Minas Gerais, 2016. He obtained the Licentiate degree in Physics by this same institution in 2011. Has experience as a teacher of High School physics. During his undergraduate degree, he has been a Scientific Initiation Fellow at the currently deactivated ' Technological Center Foundation ' (CETEC) - Opto-Electronic Materials Sector -, State of Minas Gerais, where he had introductory contacts with the Raman and infrared spectroscopy, with general spectroscopic techniques, etc., as well as software and modern equipment. This experience has been captivating because years later made me realize how important is the science that deals with the interaction between electromagnetic radiation with matter (experimentally, applied and theoretically). This science has its most fundamental description based on Quantum (and also Classical) Electrodynamics & Optics - the most scientifically proven theory(s), describing most of the known physical phenomena. In the past, he also acted reasonably, autonomously, as an amateur astronomer. He is keen on observations of the night sky, especially with binoculars. In his master's degree, he addressed a text written by Feynman whose theme is the natural connection between Classical Electromagnetism and Special Relativity (SR), that is, some introductory elements of Relativistic Electrodynamics. Feynman shows that the relativistic effects of Lorentz contraction and time dilation are naturally contained in the scope of Electromagnetic Theory, even if the velocity between inertial frames is very low. Thus, from the perspective of SR, electric and magnetic forces and fields become totally relative concepts; however, Maxwell's equations are preserved (no need for relativistic correction) in any of these frames. The invariance on the elementary charge and the Principle of charge conservation (in addition to the effects mentioned above), allow the scientist to conclude that Electromagnetism and SR are compatible! This is highlighted from a theoretical approach of the forces acting on a test charge (in different inertial frames) - which, for short time intervals, is in accordance with Einstein's postulates. More about this work, the workshop with university students, the material created with errata and proposed questions; the lesson emphasizing some SR prior knowledge (necessary to understand Feynman) and relevant notions contained in his text; the supplement produced (with answers to the suggested questions and considerations about important physical aspects related to the text); etc., can be found at
