Presenting a realistic interpretation of quantum mechanics and, in particular, a realistic view of quantum waves, this book defends, with one exception, Schrodinger's views on quantum mechanics. Johansson goes on to defend the view that the collapse of a wave function during a measurement is a real physical collapse of a wave and argues that the collapse is a consequence of quantisation of interaction. Lastly Johansson argues for a revised principle of individuation in the quantum domain and that this principle enables a sort of explanation of non-local phenomena.

'This is a fascinating book and I learnt a lot from reading it. Johansson introduces a new, highly interesting definition of realism and carries it through in a discussion of the major issues in the philosophy of quantum mechanics. In doing this he adds important new insights in the subject. I strongly recommend this book to all who are interested in the philosophy of physics.' Sven Ove Hansson, KTH (Royal University of Technology) Sweden 'Interpreting Quantum Mechanics argues for a revival of a revised version of SchrÃ¶dingerÂ´s assumption that the quantum physical reality ultimately consists of waves. It is, according to the author, an unfortunate combination of accidental historical circumstances and the mathematical difficulty of developing a wave-ontology consistent with quantisation that has hindered progress in this direction. The book convincingly argues that such an ontological program is possible and that it is the first step towards a realistic interpretation of QM. This modified version of SchrÃ¶dinger's approach capably handles well-known interpretational problems in QM, such as the Born rule, the wave-particle dualism, the measurement problem and non-locality. The presentation and discussion is carried out both on a technical and an intuitive level and is therefore accessible to philosophers without extensive background in physics, as well as physicists who do not have a philosophical background. A number of alternative contemporary ways to deal with the above four questions and the interpretation of the quantum formalism in general is also presented and evaluated in a competent and penetrating way.
