“Simulation” are key steps in the study of a System for providing the
framework to develop a comprehensive theory for interpretation and
prediction of observational data.
A “Model”, in the Mach
approach, is suggested by the existing experimental results and the
conditions imposed by general principles in order to justify
coherently the observational panorama; its validity is graded by the
capacity to suggest new experiments to validate or to contradict
hypotheses adopted by the “Theory” in an open path to progress in
knowledge and understanding.
represents a virtual experiment conceived to check the predictions
of the “Model” producing the expected results; its input is
determinant when injected back in the generator to modify the
primitive. This applies in general to the different fields of
Science (Astrophysics, Cosmology, Geology, Biology, Economy, …).
simulation are strictly interconnected and mutually supporting.
Simulations are developed on the basis of models and this interaction
generates a powerful critical analysis of the process of using simulated
experiments for theory validation. For example, it is possible the
assessment with a high level of confidence of a “Data analysis method”
by using data from a simulated experiment before applying it on the data
set from a real experiment; naturally, whatever the detail of the
simulation, the assessment will provide only necessary but not a priori
sufficient conditions on the validity of the method.
simulation by virtual experiments can approximate the real world as it
was not conceivable before; the rapid and innovating development of
available supports, like the advent of faster nano-technology for grid
and massive computing, open new perspectives for this field which
assumes more and more a distinctive individuality involving the effort
coordinated of statisticians, data analysts, and computer scientists.
The Workshop will address the basic approach to the word of simulation
and modelling in three major branches of Science: Astrophysics, Biology
and Climatology by reporting on the present status of art and adopted
lines of research. The analysis of the interrelation and the impact of
new technologies and innovative design on applied fields such as e.g.
Medicine, Pharmacology, Earth environment will represent the logical
fallout of the initiative. Today more than ever, it seems well-adequate
the phrase, cited by various authors, "A mind is like a parachute. It
doesn't work if it not open".
