THE WORLD ACCORDING TO QUANTUM MECHANICS

Apart from providing a lucid introduction to the mathematical formalism and conceptual foundations of quantum mechanics we explain why the laws of physics have the form that they do In addition we present a new and unique look at the quantum world steering clear of two common errors the error of the ψontologists who reify a calculational tool and the error of the antirealists for whom physical theories are simply devices for expressing regularities among observationsThe new edition of this acclaimed text adds around 200 pages on a variety of topics such as how the founders sought to make sense of quantum mechanics Kant39s theory of science QBism Everettian quantum mechanics de Broglie–Bohm theory environmental decoherence contextuality nonlocality and the paradox of subjectivity the curious fact that the world seems to exist twice once for us in our minds and once by itself independently of us
