SUMMARY:Philosophical Aspects of Simulations in Astrophysics and Cosmology

TZID:America/Los_Angeles
LOCATION:Social Science Tower \, Irvine\, United States
DESCRIPTION:<p>Simulations have played an essential role in the advancement of astrophysics and cosmology in recent decades\, and they will only grow more indispensable as astrophysicists pursue a deeper and more complex understanding of the highly nonlinear processes at the heart of galaxies\, clusters\, and the universe itself.&nbsp\; However\, these methods do not come without challenges and costs.&nbsp\; This workshop will bring together physicists and philosophers to explore the epistemological and methodological issues raised by simulations.&nbsp\; The first day will focus on code comparisons:&nbsp\; What lessons can we draw from comparisons between different simulation codes\, especially large-scale comparison projects such as AGORA and AQUILA?&nbsp\; What are the difficulties associated with comparing a diversity of complex simulations?&nbsp\; The second day will broadly focus on questions of model complexity: Given the limitations on our ability to test against complete analytic solutions\, how do the variety of tests and methods available work together to warrant confidence in complex simulations?&nbsp\; To what extent do the highly nonlinear interactions between model components raise worries about &ldquo\;kludges&rdquo\; or other difficulties in diagnosing the sources of inaccuracies in simulation?</p>
