By contrast, deep realists claim that realism can be legitimate only if such entities are described in metaphysical terms.

• Abstract: `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. We argue that this methodological discussion can be fruitfully applied in Everettian quantum mechanics, specifically on the debate concerning the existence of worlds and the recent dispute between Everettian actualism and quantum modal realism. After presenting what is involved in such dispute, we point to a dilemma for realists: either we don't have the available metaphysical tools to answer the deep realist's demands, and realism is not justified in this case, or such demands of metaphysical dressing are not mandatory for scientific realism, and deep versions of realism are not really required.

  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.

  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.

  According to scientific realism, science gives us an approximately true description of what the world is like. We focus on the ontological and metaphysical aspects of this discussion.

• Undecidability and unpredictability: not limitations, but triumphs of science [0.0]
  It is a widespread belief that results like G"odel's incompleteness theorems represent fundamental limitations to humanity's strive for scientific knowledge. I argue that this view is wrong. It originates in a naive form of metaphysics that sees the physical and Platonic worlds as a collection of things with definite properties. I argue to replace this perspective by a worldview in which a structural notion of real patterns', not things' are regarded as fundamental.
