Invented by the Scotsman James Watt in 1769, the steam engine revolutionized the world and introduced humans to the industrial age. The infographic of this powerful device was published in one of the sections Fique por dentro (Look inside), reserved for this kind of graphic material, of the Tempo de Ciências (Science Time) school manual for the 9th year of Editora do Brasil. The original image hardly underwent more modifications other than the inclusion of the text dedicated to the exercises for the student and the elimination of the drawing of the locomotive in the Aplicaçóes da época (Applications of the time) column.
