The calculation of the masses of the lightest nucleon resonances using lattice QCD is surveyed. Recent results for the mass of the first radial excitation of the nucleon, the Roper resonance, are reviewed and the interpretation in terms of models of hadronic resonances, such as the quark model and hadronic molecules, discussed. The talk concludes with an outline of prospects for future calculat...

Thomas Moffet (1553-1604) has been the subject of many studies. In particular, Virgil Heltzel and Hoyt Hudson, C E Raven, Hugh Trevor-Roper, Margaret Pelling, Charles Webster, Allen Debus, and Victor Houliston have contributed importantly to our understanding of the life, career, and works of one of England's earliest, and most significant, Paracelsians.' Through their work, we have come to kno...
