Galileo’s life and its guidelines
Introduction
It was the first astronomer who managed to see Saturn from Earth. Investigating, he discovered something that caught his attention. It was nothing other than Saturn’s rings. Although perhaps the fact as such is not a contribution to highlight, it is worth mentioning it. 5. The acceleration of bodies in free fall was the same regardless of weight.
Developing
The method had to meet 4 guidelines:
The observation: it becomes imperative to delimit the object of the investigation, it must be supported by observable data thoroughly, delimited and with reference to a problem to solve. Generally the problems that arise are explanatory theories where the data cannot be explained by the theory itself, but it can be through a change in the concept or an extension in the observations.
Preparation of an explanatory theory: in this step a new explanation is proposed, in the form of hypothesis or provisional, in the condition of experimental verification. Deduction of the hypothesis: also called as raised theory, the consequence of obtaining the truth is extracted, it is established that the consequences must be deductive of a mathematical type, since Galileo said that "nature is written in mathematical language".
Experiment or verification: The ideal conditions are established, measuring a minimum degree of uncertainty in the interference to measure the deduced consequences, and thus verify that the consequences are repeated in all cases. He provided a methodology that would be imitated for a long time, and whose essence captured in a famous metaphor: “Philosophy is written in that great book that we have open before the eyes, I mean, the universe, but it cannot be understood if beforeLearn to understand the language, to know the characters with which it is written. Is written in mathematical language ".
conclusion
He showed that the Aristotelian postulate was incorrect, since he claimed that the acceleration of the free fall of the bodies was proportional to their weight, when in reality he found that in vacuum all the bodies fall with equal speed. He occupied two spheres for experimentation, and made them slip down on smooth surfaces. 6. Galileo systematic method. Proposed a systematic method based on the experimental verification of the hypotheses and on the explanations of natural phenomena. The observation and demonstration were the two most important points, but also the character of evidence and documentation of the unit.
