1. Radiação térmica e a fórmula de Planck
In this paper, theoretical and experimental research on blackbody thermal radiation is discussed and historically ordered. The main thermal radiation equations following Planck’s revolutionary idea are obtained using the formalism of statistical mechanics. These equations, already well known, are deduced in a very detailed and didactic way in order to faci

3. INTRODUÇÃO ÀS REDES NEURAIS PARA REGRESSÕES NÃO-LINEARES: AJUSTE DE SUPERFÍCIES DE ENERGIA POTENCIAL
The present work demonstrates how neural networks are used to do non-linear regressions. The technique is presented in a simple and didactic manner and applied to fit potential energy surfaces for the FeC molecule and for the reaction H + H2. It shows how to do the fitting for single- and multi-variable system providing examples and code that can be easily e

8. A HISTÓRIA DA CIÊNCIA COMO “REMÉDIO” NO ENSINO DE QUÍMICA: EPISÓDIO - ESTUDO SOBRE A INVENÇÃO DA TEORIA ATÔMICO-MOLECULAR MODERNA
In recent years, much has been said about the approach of the history of science and science teaching. We know that this approach can be made using historical episodes in science classes. In this sense, this work aims to bring a historical episode to be worked on in general chemistry classes in high school, as well as in general chemistry classes 1 of univer
