Gentzen's Centenary: The Quest For Consistency

Throughout history there have been references and examples in literature, art and philosophy of an increased awareness of life while under the influence of extreme emotions - these have become known as Peak Experiences. Soon after Colin Wilson became aware of this phenomena in the 1960s he wondered about its history and how its power could be harnessed, thus began a 40 year investigation.

This work deals with the search for signatures of non-Gaussianities in the cosmic microwave background (CMB). Probing Gaussianity in the CMB addresses one of the key questions in modern cosmology because it allows us to discriminate between different models of inflation, and thus concerns a fundamental part of the standard cosmological model.
