Get PDFMachinic Ontology:Review: Mehdi Parsa, ‘Machinic Ontology’
Get PDFThe book Machinic Ontology draws parallels between books and brains and indeed models itself on a brain conceived of as a network of problems. A book is also regarded as a little machine, and in echoing Deleuze and Guattari in making this observation, Parsa’s objective in writing the book becomes apparent: it is a detailed evaluation of the becoming-concept of the machine-metaphor, one that applies a universal ‘machinism’ as a metaphysical foundation. This is a hugely important and timely undertaking, though not without various tensions, which will be examined in this review
A Square Kilometre Array Pulsar Census
Get PDFMost of the pulsar science case with the Square Kilometre Array (SKA) depends on long-term precision pulsar timing of a large number of pulsars, as well as astrometric measurements of these using very long baseline interferometry (VLBI). But before we can time them, or VLBI them, we must first find them. Here, we describe the considerations and strategies one needs to account for when planning an all-sky blind pulsar survey using the SKA. Based on our understanding of the pulsar population, the performance of the now-under-construction SKA elements, and practical constraints such as evading radio frequency interference, we project pulsar survey yields using two complementary methods for a number of illustrative survey designs, combining SKA1-Low and SKA1-Mid Bands 1 and 2 in a variety of ways. A composite survey using both Mid and Low is optimal, with Mid Band 2 focused in the plane. We find that, given its much higher effective area and survey speed, the best strategy is to use SKA1-Low to cover as much sky as possible, ideally also overlapping with the areas covered by Mid. In our most realistic scenario, we find that an all-sky blind survey with Phase 1 of the SKA with the AA* array assembly will detect slow pulsars and millisecond pulsars (MSPs) if SKA1-Mid covers the region within of the plane, while higher latitudes will be covered with SKA1-Low. The yield with AA4 is higher. One could increase these numbers by increasing the range covered by SKA1-Mid Bands 1 and 2, at the cost of a considerably longer survey. The pulsar census will enable us to set new constraints on the uncertain physical properties of the entire neutron star population. This will be crucial for addressing major SKA science questions including the dense-matter equation of state, strong-field gravity tests, and gravitational wave astronomy
