ALVAREZ G., J. L.  e  POSADAS V., Y.. La obra de Galileo y la conformación del experimento en la física. Rev. mex. fis. [online]. 2003, vol.49, n.1, pp.62-74. ISSN 0035-001X.

It is very frequent to find comments and references to Galileo's work suggesting that he based his affirmations on a logic thought and not on observations. In this paper we present an analysis of some experiments that he realized and were unknown in the XVI and XVII centuries; in they we find a clear description of the methodology that Galileo follows in order to reach the results that he presents in his formal work, particularly in Discorsi. In contrast with the Aristotelian philosophy, in these manuscripts Galileo adopt a methodology with which he obtain great contributions for the modern conformation of the experimental method, founding so a methodology for the study of the movement. We use this analysis as an example of the difficulties that are present in the conformation of the modern experimentation and we point out the necessity to stress the importance of the scientific methodology in the teaching of physics.

Palavras-chave : Galilean manuscripts; conformation of the experiment; Galileo; Galilean epistemology.
