Dirac and the dispensability of mathematics

摘要: Abstract In this paper, I examine the role of delta function in Dirac's formulation quantum mechanics (QM), and discuss, more generally, mathematics theory construction. It has been argued that mathematical theories play an indispensable physics, particularly QM [Colyvan, M. (2001). The indispensability . Oxford University Press: Oxford]. As argue here, at least case function, Dirac was very clear about its dispensability first discuss significance work, explore strategy he devised to overcome use. then even if turned out be indispensable, wouldn’t justify commitment existence entities. fact, successful uses mathematics, such as discovery antimatter, there's no need believe corresponding An interesting picture application emerges from a careful examination work.
