Nobody understands what consciousness is or how it works. Nobody understands quantum mechanics either. Could that be more than coincidence? The American physicist Richard Feynman said this about the notorious puzzles and paradoxes of quantum mechanics, the theory physicists use to describe the tiniest objects in the Universe. But he might as well have been talking about the equally knotty problem of consciousness.

The strange link between the human mind and quantum physics

Unlike classical mechanics, quantum mechanics assumes the famous Heisenberg uncertainty relations. One of these concerns time: the energy—time uncertainty relation. Unlike the canonical position—momentum uncertainty relation, the energy—time relation is not reflected in the operator formalism of quantum theory. This chapter sheds light on these questions and others, including the absorbing matter of whether quantum mechanics allows for the existence of ideal clocks.

The second section notes that quantum mechanics does not involve a special problem for time, and that there is no fundamental asymmetry between space and time in quantum mechanics over and above the asymmetry which already exists in classical physics. The third section studies time operators in detail. The fourth section discusses various uncertainty relations involving time. Keywords: time operators , classical mechanics , quantum mechanics , Heisenberg uncertainty relations , ideal clocks.

Jan Hilgevoord studied theoretical physics at the University of Amsterdam. From to he was Professor of Theoretical Physics in Amsterdam, and from until his retirement in Professor in the Philosophy of the Exact Sciences at the University of Utrecht.

He edited Physics and Our View of the World Cambridge University Press, and wrote many articles on the foundations of quantum mechanics. He has written four text books on quantum mechanics and quantum field theory Rinton Press, — , and published many articles on time, thought experiments and confirmation.

His recent interests centre on infinity in physics and the philosophy of probability. Access to the complete content on Oxford Handbooks Online requires a subscription or purchase.

Metaphysics in Contemporary Physics

Don't have an account? In this chapter it is argued that the decisive argument against the reducibility of causal relations comes from quantum physics. Nonetheless, it is argued that quantum entanglement by no means implies that we have to abandon an ontology of objects in favour of an ontology of structures. All extant proposals for a quantum ontology of matter in spacetime are committed to objects, whose dynamics are determined not by their local, intrinsic properties, but by an holistic property instantiated by all the objects together—a structure that takes all the objects in the universe as its relata. The view set out in this chapter combines ontic structural realism with an ontology of objects that can be conceived as substances.

The Reality of Relations

The study and interpretation of quantum phenomena have generated a lively debate not only among physicists but also among philosophers, from a multiplicity of perspectives. There seems to be broad agreement among physicists that the worldview depicted by quantum mechanics is radically different from the one of classical mechanics. These three essays are briefly introduced in what follows. But recently it has been acknowledged that we do not have to interpret quantum theories as theories of the wave function. Various proposals have been made, whereby, as in classical theories, the world is described by trajectories of microscopic stuff in space—time that compose macroscopic objects.

E-mail: maldonadocarlos unbosque. Probably the crux of quantum science is the relationship between consciousness and reality. The name for that relation is varied, and points out to a most fundamental problem, namely the possibility to overcome dualism.

This review, of the understanding of quantum mechanics, is broad in scope, and aims to reflect enough of the literature to be representative of the current state of the subject. To enhance clarity, the main findings are presented in the form of a coherent synthesis of the reviewed sources. The review highlights core characteristics of quantum mechanics. One is statistical balance in the collective response of an ensemble of identically prepared systems, to differing measurement types.

Esfeld, Michael Quantum entanglement and a metaphysics of relations. This paper argues for a metaphysics of relations based on a characterization of quantum entanglement in terms of non-separability, thereby regarding entanglement as a sort of holism. By contrast to a radical metaphysics of relations, the position set out in this paper recognizes things that stand in the relations, but claims that, as far as the relations are concerned, there is no need for these things to have qualitative intrinsic properties underlying the relations. This position thus opposes a metaphysics of individual things that are characterized by intrinsic properties.

We see one cat and then another cat.

 Какой у нас выбор? - спросила Сьюзан. Она хорошо понимала, что в отчаянной ситуации требуются отчаянные меры, в том числе и от АНБ. - Мы не можем его устранить, если ты это имела в виду.

Сьюзан ждала, вглядываясь во тьму и надеясь, что Стратмор если и пострадал, то не сильно. После паузы, показавшейся ей вечностью, она прошептала: - Коммандер. И в тот же миг осознала свою ошибку. Она ощутила запах Хейла, но повернулась слишком поздно. И тут же забилась, задыхаясь от удушья.

 Да, сэр. Уверен, что человеку вашего положения хорошо известно, что канадское правительство делает все для защиты соотечественников от неприятностей, которые случаются с ними в этих… э-э… скажем так, не самых передовых странах. Тонкие губы Клушара изогнулись в понимающей улыбке.

Он снова посмотрел на Джаббу и закрыл.  - Танкадо отдал кольцо с умыслом. Мне все равно, думал ли он, что тучный господин побежит к телефону-автомату и позвонит нам, или просто хотел избавиться от этого кольца. Я принял решение. Мы вводим эту цитату.

Это все, что я могу вам сказать. Я уполномочен заплатить вам за. На мгновение в комнате повисла тишина, затем Росио приоткрыла губы в хитрой улыбке. - Ну видите, все не так страшно, правда? - Она села в кресло и скрестила ноги.

Вроде бы на нижней ступеньке никого. Может, ему просто показалось. Какая разница, Стратмор никогда не решится выстрелить, пока он прикрыт Сьюзан. Но когда он начал подниматься на следующую ступеньку, не выпуская Сьюзан из рук, произошло нечто неожиданное.
