SUMMARY:International Conference: Hypothesis in science. 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. However, just because a certain model or hypothesis is non-explanator
y does not necessarily mean that it cannot play any descriptive or predicti
ve role. What criteria do we have then to evaluate our scientific hypothese
s, models or theories?\nOur conference aims to address the role of hypothet
ical thinking in the formulation and development of scientific theories and
models.\n \n

sp;anniversary of the birth of Nicolaus Copernicus
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.
