Este artículo habla de la experiencia de Thomas Kuhn como físico: su educación en la disciplina, su servicio como experto durante la Segunda Guerra Mundial, y su investigación doctoral. Estudiamos un lapso de tiempo que va de 1940 a 1951. El objetivo en última instancia es ofrecer base empírica para valorar una afirmación como la de Mara Beller (1999), que dice que la descripción kuhniana de la ciencia normal está parcialmente basada en circunstancias y experiencias personales, no sólo en los datos históricos o en la evidencia disponible de la sociología de la ciencia. En este artículo se establece que dicha tesis es plausible.

ABSTRACT: Carajás Mineral Province, Amazon region, is the most important one in Brazil. Vale S.A. Company has the right to operate in the area of the N5E mine. The work is conducted on rock alteration products of low geomechanical quality related to sandstones, siltstones, and a lateritic cover. In order to monitor ground deformation, 33 TerraSAR-X images covering the period of March 2012-April 2013 were used in the investigation. An interferometric synthetic aperture radar (InSAR) approach based on permanent scatterer interferometry (PSI) using an interferometric point target analysis algorithm was applied. Results demonstrated that most of the area was considered stable during the time span of the image acquisition. However, persistent scatterers (PSs) with high deformation rates were mapped over a landfill probably related to settlements. To validate the PSI data, graphs were generated with the displaced information based on topographic measurements in the field. The graphs showed that the surface deformations during TSX-1 runway coverage are within the miner’s safety threshold and do not present a risk of major problems. The PSI data provided a synoptic and detailed view of the deformation process that affects the mining complex without the need of field campaign or instrumentation.
