The 550th anniversary of the birth of Nicolaus Copernicus LOCATION:Nicolaus Copernicus University in Toruń DESCRIPTION:Hypothesis in science. The 550th anniversary of the birth of Nicolaus Coper nicusIt is sometimes assumed that the heliocentric (Copernican) and geocent ric (Ptolemaic) systems were considered to be equally valid for a long peri od of time. On the contrary, there are descriptive, and (at least in part) predictive differences between the two models. These differences became eve n more substantial after the discovery of the telescope. The availability o f considerably more new observations and data forced astronomers to abandon the Ptolemaic system, which was no longer able to justify certain physical observations. Rather than the geocentric, it was the geo-heliocentric mode l (proposed by Tycho Brahe) which became the real antagonist to heliocentri sm, since the latter model was able to justify the motions of celestial obj ects based on observational evidence. However, for geometric description to also provide an explanation, astronomy needed to change its disciplinary g oals. This happened when Newton proposed universal gravitation as an explan ation for Kepler’s elliptical orbits. When Kepler’s description of these or bits was combined with Newton’s explanation, the geo-heliocentric model los t even more explanatory power, while the heliocentric model was reinforced. \nIf certain astronomical models and their equations can provide nothing mo re than an empirical description of the explanandum, then one may seek to p rovide the answer to the following question: could it be that in the geomet rically-based astronomical models mentioned above there is something that h elps us to distinguish merely descriptive from explanatory models? Since ma thematical dependencies of scientific theories do not necessarily specify t he causal dependencies that produce the explanandum, we probably do not kno w whether our hypotheses correctly describe the world. Thus, those hypothes es are nothing more than useful tools with which to organise observational data.

It is so metimes assumed that the heliocentric (Copernican) and geocentric (Ptolemai c) systems were considered to be equally valid for a long period of time. O n the contrary, there are descriptive, and (at least in part) predictive di fferences between the two models. These differences became even more substa ntial after the discovery of the telescope. The availability of considerabl y more new observations and data forced astronomers to abandon the Ptolemai c system, which was no longer able to justify certain physical observations . Rather than the geocentric, it was the geo-heliocentric model (proposed b y Tycho Brahe) which became the real antagonist to heliocentrism, since the latter model was able to justify the motions of celestial objects based on observational evidence. However, for geometric description to also provide an explanation, astronomy needed to change its disciplinary goals. This ha ppened when Newton proposed universal gravitation as an explanation for Kep ler’s elliptical orbits. When Kepler’s description of these orbits was comb ined with Newton’s explanation, the geo-heliocentric model lost even more e xplanatory power, while the heliocentric model was reinforced.
If cer tain astronomical models and their equations can provide nothing more than an empirical description of the explanandum, then one may see k to provide the answer to the following question: could it be that in the geometrically-based astronomical models mentioned above there is something that helps us to distinguish merely descriptive from explanatory models? Si nce mathematical dependencies of scientific theories do not necessarily spe cify the causal dependencies that produce the explanandum, we probably do not know whether our hypotheses correctly describe the world. Thus, those hypotheses are nothing more than useful tools with which to org anise observational data. However, just because a certain model or hypothes is is non-explanatory does not necessarily mean that it cannot play any des criptive or predictive role. What criteria do we have then to evaluate our scientific hypotheses, models or theories?
Our conference aims to add ress the role of hypothetical thinking in the formulation and development o f scientific theories and models.
