Reproducibility

The reproducibility of an scientific experiment is one of the conditions which makes it possible to include the observations carried out during this experiment in the process of perpetual improvement of the scientific knowledge. This condition leaves the principle which one can draw from conclusions only of one event described well, which appeared several times, caused by different people. This condition makes it possible to be freed from random effects coming to distort the results as well as error of judgments or handling on behalf of the scientists.

The criterion of reproducibility is one of the conditions on which the philosopher Karl Popper distinguishes the scientific character from a study.

For all the applied sciences, the Probabilité S provide a mathematical model explaining the variability of the results.

Observations and reproducibility

A phenomenon is observed. It then is indexed and classified in a category of Observable.

The list can be long phenomena allegedly " observés" who did not reproduce: one speaks then about appearances . But the list of the phenomena observed and a reproducible way is infinitely longer and constitutes the base of sciences.

Science is interested especially in the phenomena which reproduce and the ideal is capacity at will to reproduce them. A phenomenon which one can reproduce at will becomes a reproducible phenomenon with the scientific direction.

Even if certain phenomena (e.g.: the solar activity) are not controllable thus nonreproducible, their follow-up makes it possible to draw some from the rules of evolution in time: the periodicity or an evolution in time is a reproducible phenomenon with the direction where one can envisage the evolution in time: it is foreseeable within the meaning of the temporal evolution.

All the men are mortals, I am a man, therefore I am mortal. The man is mortal and science, to date, did not observe any living being which is immortal. The rule observed is thus: any living being is mortal. the immortal one is field of not observed. However, it is not excluded that in the future an immortality exists, it to date is not observed.

Science functions while drawing from reproducible observations of the " lois" or " principes" who have as principal property of to be true as long as no observation proved the opposite.

The reverse does not have any direction: to state, starting from no observation, a rule and to pose it as law under the pretext which one can prove that it is false are not scientific discipline.
