64. [quant-ph/9611048] The Quantum Theory Of Ur-Objects As A Theory Of Information Here the quantum theory of urobjects proposed by C. F. von Weizsaecker is reviewed, and the philosophical consequences of its interpretation as an information theory are demonstrated by means of some important concepts of physics such as time, space, entropy, energy, and matter, which in ur theory appear to be directly connected with information as ''the'' fundamental substance. http://arxiv.org/abs/quant-ph/9611048

Quantum Physics, abstract quant-ph/9611048 From: Holger Lyre [ view email ] Date: Tue, 26 Nov 1996 09:28:24 MST (11kb) The Quantum Theory of Ur-Objects as a Theory of Information Authors: Holger Lyre Comments: 11 pages Journal-ref: Int.J.Theor.Phys. 34 (1995) 1541 The quantum theory of ur-objects proposed by C. F. von Weizsaecker has to be interpreted as a quantum theory of information. Ur-objects, or urs, are thought to be the simplest objects in quantum theory. Thus an ur is represented by a two-dimensional Hilbert space with the universal symmetry group SU(2), and can only be characterized as ''one bit of potential information''. In this sense it is not a spatial but an ''information atom''. The physical structure of the ur theory is reviewed, and the philosophical consequences of its interpretation as an information theory are demonstrated by means of some important concepts of physics such as time, space, entropy, energy, and matter, which in ur theory appear to be directly connected with information as ''the'' fundamental substance. This hopefully will help to provide a new understanding of the concept of information.

quantum mechanics or quantum theory , branch of mathematical physics that deals with the emission and absorption of energy by matter and with the motion of material particles. Because it holds that energy and matter exist in tiny, discrete amounts, quantum mechanics is particularly applicable to elementary particles and the interactions between them. According to the older theories of classical physics, energy is treated solely as a continuous phenomenon (i.e., waves), and matter is assumed to occupy a very specific region of space and to move in a continuous manner. According to the quantum theory, energy is emitted and absorbed in a small packet, called a quantum (pl. quanta), which in some situations behaves as particles of matter do; particles exhibit certain wavelike properties when in motion and are no longer viewed as localized in a given region but as spread out to some degree. The quantum theory thus proposes a dual nature for both waves and particles, with one aspect predominating in some situations and the other predominating in other situations. Quantum mechanics is needed to explain many properties of matter, such as the temperature dependence of the specific heat of solids, as well as when very small quantities of matter or energy are involved, as in the interaction of elementary particles and fields, but the theory of

David Deutsch This interview appeared in Philosophy Now December 2000 David Deutsch Filiz Peach about his work and hopes. The Fabric of Reality The Fabric of Reality Professor Deutsch, could you please tell our readers why you became interested in quantum physics? I am interested in anything that is fundamental. Quantum physics and the General Theory of Relativity are the two most fundamental theories that physics has. They are the theories within which other theories are formulated; they provide the framework for all of physics. So how did you first become involved? So you now believe that quantum mechanics will provide a unifying theory of the universe? Quantum mechanics is very complex. And there are still unresolved areas. Do you think the mystery of it may be resolved, say, within 20 years or so? Or is that too optimistic? What scientists or philosophers have most influenced your own work? Let us deal with the philosophers first because that is a shorter list. I think it is principally Karl Popper, and to a lesser extent Jacob Bronowski (through The Ascent of Man) and William Godwin, who is a very underrated 18th century philosopher, with a broader, more integrated and more sophisticated perspective that, say, Locke or Hume. He is underrated because he made serious mistakes too. For instance, he completely misunderstood economics and that led him to advocate a sort of communistic lifestyle. Yet many of his political ideas are actually spot on, and very modern. In the context of the current interest in human consciousness how do you see the relationship between the material explanation of the human being and consciousness? How does consciousness fit into the quantum world?

th November, 1998 Does the 'many-worlds' interpretation of quantum mechanics imply immortality? James Higgo 18 Harcourt Terrace London SW10 9JR e-mail j@higgo.com Abstract The 'Many-Worlds' Interpretation of Quantum Physics The weirdness of quantum physics can be seen in the famous parallel-slit experiment. This shows that individual photons seem to split into two particles which can nevertheless interfere with each other as if they were waves. The 'Copenhagen Interpretation' of the phenomena and the equations which describe them, agreed at the 1927 Solvay conference, essentially says that the 'wave packet' somehow associated with a particle 'collapses' when it is observed - this necessitates a relationship between the observer's consciousness and the particle. The MWI, on the other hand, holds that the equations used to predict quantum mechanical events continue to hold after observation - it is just that all things happen simultaneously, but due to 'decoherence' we do not actually see, for example, a radioactive source both decay and not decay. For an explanation of how this implies parallel universes, see Vaidman (1996). There is one way of proving that the MWI is true and the Copenhagen and other interpretations are wrong. Unfortunately, the experimenter can only prove it to himself, and never persuade anyone else of its validity.

In a sense, the way the experiment is carried out now determines whether each photon -billions of years ago - acted like a particle, going one way or the other around the galaxy and ending up in one of the two detectors (a and b),or like a wave, going both ways around the galaxy and generating an interference pattern (c). In ancient Greece, Plato tried to think an talk his way to the truth in extended dialogues with his disciples.Today physicists such as Leonard Mandel of the University of Rochester operate in a somewhat different fashion.He and his students,who are more likely to wear t-shirts and laser proof goggles than robes and sandals,spend countless hours bent over a large metal table trying to align a laser with a complex network of mirrors,lenses, beam splitters and light detectors. Plato Yet the questions they address in their equipment-jammed laboratory are no less profound than those contemplated by Plato in his grassy glade.What are the limits of human knowledge? Is the physical world shaped in some sense by our perception of it? Is there an element of randomness in the universe,or are all events predetermined?

Abstract This paper is a response to some recent discussions of many-minds interpretations in the philosophical literature. After an introduction to the many-minds idea, the complexity of quantum states for macroscopic objects is stressed. Then it is proposed that a characterization of the physical structure of observers is a proper goal for physical theory. It is argued that an observer cannot be defined merely by the instantaneous structure of a brain, but that the history of the brain's functioning must also be taken into account. Next the nature of probability in many-minds interpretations is discussed and it is suggested that only discrete probability models are needed. The paper concludes with brief comments on issues of actuality and identity over time. Keywords: quantum theory, many minds, many worlds, Everett

The theory describes only the way systems affect each other in the course of physical interactions.

Abstract An investigation is made into how the foundations of statistical mechanics are affected once we treat classical mechanics as an approximation to quantum mechanics in certain domains rather than as a theory in its own right; this is necessary if we are to understand statistical-mechanical systems in our own world. Relevant structural and dynamical differences are identified between classical and quantum mechanics (partly through analysis of technical work on quantum chaos by other authors). These imply that quantum mechanics significantly affects a number of foundational questions, including the nature of statistical probability and the direction of time.

333. Wilhelm und Else Heraeus-Seminar New Frontiers in Quantum Theory and Measurement September 1 - September 5, 2004 Schloss Reisensburg, Germany HOME SCHEDULE DIRECTIONS Organizers This seminar is organized by the at the and the Wilhelm und Else Heraeus-Stiftung For further information, please contact our secretary Background The enormous success of experimental quantum optics has led to the realization of many popular “Gedanken-experiments” symbolizing the subtleties of the measurement process in quantum mechanics. Ion traps, cavity QED, matter-wave optics and non-linear optics are the foremost topics that have essentially contributed to this field. Atomic entanglement, non-classical states of the radiation field, engineering of decoherence, quantum teleportation and interference of large molecules represent excellent examples of quantum-optical effects that have already entered textbooks of quantum mechanics. At the same time, theoretical physics has provided a continuous stream of new tools and ideas such as quantum trajectories, einselection, control of decoherence and quantum thermodynamics that give a fresh impetus on current research. In this seminar leading experimentalists and theoreticians will present their work providing a broad variety of topics. Together with the inspiring atmosphere of “Schloss Reisensburg”, the talks will lead to stimulating discussions with a schedule that is designed to leave ample time for this purpose. All young scientists are encouraged to contribute their work in poster sessions and to actively participate in the “Wilhelm und Else Heraeus-Seminar”.

Quantum Theory timeline At the start of the twentieth century, scientists believed that they understood the most fundamental principles of nature. Atoms were solid building blocks of nature; people trusted Newtonian laws of motion; most of the problems of physics seemed to be solved. However, starting with Einstein's theory of relativity which replaced Newtonian mechanics, scientists gradually realized that their knowledge was far from complete. Of particular interest was the growing field of quantum mechanics, which completely altered the fundamental precepts of physics. Particles discovered 1898 - 1964: Max Planck suggests that radiation is quantized (it comes in discrete amounts.) Albert Einstein , one of the few scientists to take Planck's ideas seriously, proposes a quantum of light (the photon) which behaves like a particle. Einstein's other theories explained the equivalence of mass and energy, the particle-wave duality of photons, the equivalence principle, and special relativity. Hans Geiger and Ernest Marsden , under the supervision of Ernest Rutherford , scatter alpha particles off a gold foil and observe large angles of scattering, suggesting that atoms have a small, dense, positively charged nucleus.

Partington) (science, original, smirk) Philosophers have long wondered why socks have this habit of getting lost, and why humans always end up with large collections of unmatched odd socks. One school of thought says that socks are very antisocial creatures, and have a deep sense of rivalry. In particular, two socks of the same design have feelings of loathing towards each other and hence it is nearly impossible to pair them (e.g. a blue sock will usually be found nestling up to a black one, rather than its fellow blue sock). On the other hand, quantum theorists explain it all by a generalised exclusion principleit is impossible for two socks to be in the same eigen-state, and when it's in danger of happening, one of the socks has to vanish. Indeed the Uncertainty Principle also comes inthe only time you know where a sock is, is when you're wearing it, and hence unable to be sure exactly how fast it's moving. The moment you stop moving and look at your sock, it then starts falling to pieces, changing colour, or otherwise becoming indeterminate. Either way, socks may possess Colour and Strangeness, but they seem to lack Charm. Browse the Best of RHF: " Computer, Science and Math Jokes

80. General Term: Quantum Theory quantum theory. quantum theory grew out of a series of anomalies in the picture of matter and light offered by Newtonian physics http://www.meta-library.net/physgloss/qm-body.html

Quantum Theory Quantum theory grew out of a series of anomalies in the picture of matter and light offered by Newtonian physics - in particular associated with black-body radiation, the photo-electric effect , and the need to devise a model of the atom consistent with the newly discovered subatomic particles. Important principles of quantum theory include its statistical nature, and the uncertainty principle which sets a limit on our knowledge of physical systems. The implications of the theory for the nature of reality are much discussed (see Implications of the new physics). Most quantum theorists accept an intrinsic element of probability in fundamental physics, and also the need to see systems as wholes rather than merely dissecting them into their simplest components. Related Topics: Physics The empirical basis for quantum physics lies in such phenomena as blackbody radiation, the photoelectric effect, the specific heats of solids, the stability of the structure and the emission spectrum of atoms, all of which remained unexplainable in terms of classical physics. In 1901, Max Planck photons Einstein in 1905 explained the photoelectric effect as well as the specific heat two years later. In 1913
