• Abstract: Scientific realism is the philosophical stance that science tracks truth, in particular in its depiction of the world's ontology. Ontologically, this involves a commitment to the existence of entities posited by our best scientific theories; metaontologically, it includes the claim that the theoretical framework itself is true. In this article, we examine wave function realism as a case study within this broader methodological debate. Wave function realism holds that the wave function, as described by quantum mechanics, corresponds to a real physical entity. We focus on a recent formulation of this view that commits to the ontology of the wave function while deliberately avoiding the metaontological question of the framework's truth. Instead, the view is defended on pragmatic, non-truth-conductive grounds. This, we argue, raises tensions for the purported realism of wave function realism and its compatibility with scientific realism more broadly.

  We offer philosophical motivations for a method we call Virtual World Cognitive Science (VW CogSci) Researchers use virtual embodied agents that are embedded in virtual worlds to explore questions in the field of Cognitive Science. We focus on questions about mental and linguistic representation and the ways that such computational modeling can add rigor to philosophical thought experiments.

• Can we "effectivize'' spacetime? [6.793496936204057]
  According to textiteffective realism, scientific theories give us knowledge about the unobservable world, but not at the fundamental level. This view is justified by the well-received textiteffective-field-theory (EFT) approach to physics. I explain the motivations for the EFT approach and effective realism and their benefits.

• Whence deep realism for Everettian quantum mechanics? [0.0]
  Shallow' and deep' versions of scientific realism may be distinguished as follows: the shallow realist is satisfied with belief in the existence of the posits of our best scientific theories. By contrast, deep realists claim that realism can be legitimate only if such entities are described in metaphysical terms.

• Resource theory of imaginarity: Quantification and state conversion [48.7576911714538]
  Resource theory of imaginarity has been introduced, allowing for a systematic study of complex numbers in quantum mechanics and quantum information theory. We investigate imaginarity quantification, focusing on the geometric imaginarity and the robustness of imaginarity, and apply these tools to the state conversion problem in imaginarity theory. Our study reveals the significance of complex numbers in quantum physics, and proves that imaginarity is a resource in optical experiments.
