The literary form of the course goes beyond practitioners’ commonplace books, for it aims at teaching practical geometry on a solid Euclidean basis while claiming that the entire practical geometry consists of the brief and easy use of pantometers, that is, Coignet-type sectors. Actually, the course focuses on checking the solid geometric foundations of the scales graduation, which would justify the numerical consideration of continuous magnitudes as quantities –accepting a margin of error sensorially imperceptible and irrelevant for the purposes of application. info:eu-repo/grantAgreement/ES/MINECO-FEDER/HAR2015-70985-P info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 0.103 2022 History and Philosophy of Science 2022 Q4 History 2022 Q4 0.2 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 9999 998 Universidad de Zaragoza Dpto.
