Restoring Parmenides' Poem: Essays toward a New Arrangement of the Fragments Based on a Reassessment of the Original Sources

The history of philosophy proper, claimed Hegel, began with the poem of the Presocratic Greek philosopher Parmenides. Today, that poem is extant only in fragmentary form, the various fragments surviving as quotations, translations, or paraphrases in the works of better-preserved authors of antiquity. These range from Plato, writing within a century after Parmenides' death, to the sixth-century C.E. commentator Simplicius of Cilicia, the latest figure known to have had access to the compete poem. Since the Renaissance, students of Parmenides have relied on collections of fragments compiled by classical scholars, and since the turn of the twentieth century, Hermann Diels' Die Fragmente der Vorsokratiker, through a number of editions, has remained the standard collection for Presocratic material generally and for the arrangement of Parmenides' fragments in particular. This dissertation is an extended critique of that arrangement. I argue that the reconstructions of Parmenides' poem in the last two centuries suffer from a number of mistakes. Those errors stem from a general failure to appreciate the peculiar literary character of his work as well as the mishandling, in particular instances, of the various sources that preserve what remains of his verse. By reconsidering a number of rarely questioned assumptions underlying the standard presentations and by revisiting the source material with greater care, a number of scholarly impasses that have beset the discussion of this difficult text are resolved, and the foundations for a more faithful and fuller reconstruction of Parmenides' work are established

Massive stars and their supernovae

Stars more massive than about 8-10 solar masses evolve differently from their lower-mass counterparts: nuclear energy liberation is possible at higher temperatures and densities, due to gravitational contraction caused by such high masses, until forming an iron core that ends this stellar evolution. The star collapses thereafter, as insufficient pressure support exists when energy release stops due to Fe/Ni possessing the highest nuclear binding per nucleon, and this implosion turns into either a supernova explosion or a compact black hole remnant object. Neutron stars are the likely compact-star remnants after supernova explosions for a certain stellar mass range. In this chapter, we discuss this late-phase evolution of massive stars and their core collapse, including the nuclear reactions and nucleosynthesis products. We also include in this discussion more exotic outcomes, such as magnetic jet supernovae, hypernovae, gamma-ray bursts and neutron star mergers. In all cases we emphasize the viewpoint with respect to the role of radioactivities
