Irrational Axions as a Solution of The Strong CP Problem in an Eternal Universe

We exhibit a novel solution of the strong CP problem, which does not involve any massless particles. The low energy effective Lagrangian of our model involves a discrete spacetime independent axion field which can be thought of as a parameter labeling a dense set of θ vacua. In the full theory this parameter is seen to be dynamical, and the model seeks the state of lowest energy, which has θeff...

An Irrational Construction of R from Z

This paper reports on a construction of the real numbers in the ProofPower implementation of the HOL logic. Since the original construction was implemented, some major improvements to the ideas have been discovered. The improvements involve some entertaining mathematics: it turns out that the Dedekind cuts provide many routes one can travel to get from the ring of integers, Z, to the field of r...

Irrational healers?

But there must be some further rules shaping the dynamics of prescribing than these heuristics, or alternately some of those listed must be capable of more than 1 application. Consider the dynamics of prescribing within the pediatric mental health field. Over the course of 25 years, the prescribing of stimulants to children has grown exponentially – primarily in North America. In this case, cli...

Irrational principals

Timothy Besley’s Principled Agents? carefully surveys the modern social science literature on political agency problems and tries to chart a sensible middle course between the naive assumption that politicians maximize the public welfare and the pessimism of Virginia-style public choice. However, the literature that Besley showcases is seriously flawed. By building on the empirically discredite...
