SUMMARY:Maximum Entropy Reasoning: From Cosmological Likelihood Functions 
 to Quantum Field Theory - Steven Gratton (IoA)

DESCRIPTION:In this talk I review the maximum entropy principle and discus
 s its use in obtaining usable probability distributions for measurable qua
 ntities.  I argue that maximum entropy reasoning gives a Bayesian motivati
 on for certain "high-l" cosmological likelihood approximations\, useful fo
 r the analysis of large cosmic microwave background datasets such as that 
 expected from the Planck mission.  I then show how the principle provides 
 a means to systematically improve such approximations should the need aris
 e.  In light of the reasoning applied\, I end by discussing connections be
 tween maximum entropy reasoning and quantum field theory.\n
