Explorando história da ciência na Amazônia: o Museu Interativo da Física
(Universidade Federal do Pará, 2016-08) CALDAS, Jocasta; LIMA, Marcelo Costa de; CRISPINO, Luís Carlos Bassalo
In 2008, professors and students of the Physics Department of the Federal University of Pará realized a pioneering initiative for the dissemination of the History of Science in the Brazilian Amazonia. This initiative, named Physics Interactive Museum, started to act in partnership with the Amazonian community, its governmental organizations, other universities, state and municipal schools of the Pará State aiming to collaborate with the enhancement of the quality of science education in the region. We present the activities of the Physics Interactive Museum and the impact of its participation in the dissemination of History of Science in the Brazilian Amazonia.

Sobre a representação mecânica das forças elétrica, magnética e galvânica, de William Thomson: uma leitura comentada
(Universidade Federal do Pará, 2017-03) LIMA, Marcelo Costa de; COSTA, R. S.
We present and comment the homonimous article originally published by William Thomson, in 1847, in which the author explores the analogy between the estates of deformation in an elastic solid and the configurations of Faraday's lines of force. In this article Thomson has introduced for the first time the magnetic potential vector, associated in this context with rotational deformations in the solid. We present as well, the historical context in which Thomson's original paper has been conceived.
