- W4283274281 abstract "This chapter presents a first case study: nuclear models around the 1930s–1950s. It introduces a number of scientific perspectives at play around 1900–1924 and shows how this plurality of intersecting perspectives made it possible to establish a modally robust phenomenon concerning the stability of some nuclides with special or ‘magic’ numbers, as they became known. The inference <italic>from data</italic> about abundances in meteorites, ores, rocks, silicate melts, and so forth, <italic>to the phenomenon</italic> of nuclear stability was <italic>perspectival</italic> in distinctive ways. It required a number of <italic>experimental, theoretical, and technological resources</italic> spread out across a number of scientific communities at the time. This plurality of scientific perspectives allowed <italic>reliable</italic> scientific knowledge claims about, for example, the percentages of particular elements in rocks, alloys in meteorites, and gases in the atmosphere. The <italic>methodological-epistemic principles</italic> that justified the reliability of the knowledge claims so advanced were themselves perspectival and ranged from principles of normative petrology to those of crystal structure, chemistry, and nuclear physics. The exploratory nature of the 1930s–1950s nuclear models is rooted in their historical evolution in response to new data (e.g. neutron-capture cross-sections, large quadrupole moments) becoming available and new phenomena (e.g. nuclear fission, nuclear prolate shape) being inferred from these data over time. The nuclear models enabled a variety of epistemic communities to make <italic>relevant and appropriate inferences</italic> to explore what is possible about the nucleus, its internal structure, isotopic stability, and so forth." @default.
