   Everett's relative-state construction in quantum theory has never been satisfactorily expressed in the Heisenberg picture. What one might have expected to be a straightforward process was impeded by conceptual and technical problems that we solve here. The result is a construction which, unlike Everett's one in the Schrödinger picture, makes manifest the locality of Everettian multiplicity, its inherently approximative nature and its origin in certain kinds of entanglement and locally inaccessible information. (By

   In the second horn, since the imposition of the causal framework makes no difference to the factual content of the sciences, it is revealed as an empty honorific. (2003: 3–4) For causal notions to play a legitimate role in physics, Norton claims they must do so as part of an acceptable “principle of causality” that provides a universal constraint on all physical theories. What form might such a principle take? The physicist Erwin Schrödinger proposed a causal principle that combines some of the options canvased by Norton—determinism, locality, and temporal asymmetry: the exact situation at any…

   [ 6 ] In Bell (1976) and (1990), Bell derives the factorizability condition from a condition he calls the Principle of Local Causality (see Norsen 2011 for discussion). In (1990) he begins his analysis with a rehearsal of the reason that relativity should be taken to prohibit superluminal causation. On the usual notion of causation, the cause-effect relation is taken to be temporally asymmetric, with causes temporally preceding their effects. In a relativistic spacetime, events at spacelike separation are taken to have no temporal order. Any system of coordinates will assign time coordinates t…

   Causal notions can, if at all, only be legitimately employed in contexts in which we can isolate a small set of factors of interest as those responsible for the occurrence of an event—the dominant cause or causes—by drawing a distinction between causes and background conditions. Yet such a distinction, it is argued, cannot be drawn in physics. Call this the dominant cause challenge. Causes necessitate their effects, but the fundamental laws of physics are non-deterministic. This is the determinism challenge. Causal relations are relations among spatio-temporally localized events, yet fundament…

   The word 'uncertainty', in the context of quantum mechanics, usually evokes an impression of an essential unknowability of what might actually be going on at the quantum level of activity, as is made explicit in Heisenberg's uncertainty principle, and in the fact that the theory normally provides only probabilities for the results of quantum measurement. These issues limit our ultimate understanding of the behaviour of things, if we take quantum mechanics to represent an absolute truth. But they do not cause us to put that very 'truth' into question. This article addresses the issue of quantum…

   Rather, in moving at time \(t\) it inconsistently occupies a small finite (Planck length) lozenge of space, which is made up of the positions it takes in the corresponding lozenge of time surrounding \(t\). This gives a natural intrinsic account of motionlessness at \(t\), namely that there is no contradiction in its position at \(t\). One can propose an account of velocity, as varying with the length of the lozenge or spread of position in the direction of motion. There are applications in Quantum Theory, too. The Heisenberg uncertainty of position may simply be the size of the spread or smea…

   In analogy to the case of the determinism challenge, one can resist the conclusion of the argument by denying premise 1 and maintain that causal constraints can play a legitimate and useful role in physical theorizing even if they are not part of a universal principle of causality. Thus, one could maintain that the relativistic constraint that influences do not propagate faster than the speed of light is a genuinely causal constraint, which functions as a desideratum on physical theories but does not lose its legitimacy and importance should it not be satisfied by all successful theories of ph…

   Lawrence et al. have presented an argument purporting to show that "relative facts do not exist" and, consequently, "Relational Quantum Mechanics is incompatible with quantum mechanics". The argument is based on a GHZ-like contradiction between constraints satisfied by measurement outcomes in an extended Wigner's friend scenario. Here we present a strengthened version of the argument, and show why, contrary to the claim by Lawrence et al., these arguments do not contradict the consistency of a theory of relative facts. Rather, considering this argument helps clarify how one should

   In addition, this set of conditions will not strictly imply that X and Y are probabilistically correlated. We will return to these issues in Section 7 . 3. Historical Background The Direction of Time (Reichenbach 1956) was unfinished at the time of Reichenbach’s death in 1953. The manuscript was edited by his wife Maria Reichenbach, and published posthumously in 1956. The book was concerned with temporally asymmetric phenomena—phenomena that we associate with the distinction between the past and the future. It included major sections on the role of time in classical physics, thermodynamics, st…
