    Extractions: by: Brian J. Reardon It has been argued that the act of doing laundry followed the discovery of clothing by only a few weeks. While this fact has been regarded to be fantastically trivial, one can not ignore the enigmas that the act of doing laundry has created. This is especially true in the age of high speed washers and dryers. In the early days, the disappearance of articles of clothing could simply be accounted for by saying that the sock was lost in the river. Unfortunately, such excuses can no longer be used today. The availability of high speed automated washers and dryers has provided a number of fundamental questions that can not be answered using the classical laundry theory (i.e.: the river washed the sock away). Such questions include: Where, exactly does lint come from and why does the quantity of lint change from load to load?

    Extractions: Quantum mechanics is the description of motion and interaction of particles at the small scales where the discrete nature of the physical world becomes important. Quantum mechanics represented a fundamental break with classical physics , in which energies and angular momenta were regarded as continuous quantities that could change by arbitrary amounts. The first break with classical physics was performed by Planck who, in order to explain the observed spectrum of a blackbody, was forced to postulate that the oscillators in a blackbody could attain only certain quantized energies. Niels Bohr had a large influence on the development of quantum mechanics through his so-called " Copenhagen Interpretation ," a philosophical construct which was formulated to provide a fundamental framework for understanding the implicit assumptions, limitations, and applicability of the theory of quantum mechanics. Einstein subsequently postulated that electromagnetic radiation could exist only in discrete units, called

    Extractions: 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. References and citations for this submission:

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

    Extractions: The Future of Physics? My name is Mendel Sachs. My subject is theoretical physics. I have recently become aware of this excellent means of communicating ideas to my fellow physicists. I would like to ask your indulgence in some of my thoughts about physics today. I have discovered during my professional career that in order to increase our comprehension of the material world, it is necessary to ask significant questions and then try to answer them, as completely and rigorously as possible no matter how hard this may seem to be at the outset. A "significant question" to me is one whose answer could possibly increase our understanding. Of course, there is no guarantee at the outset that the question would turn out to be significant in the final analysis. On the other hand, it is often clear when a question (that a great deal of attention may be given to) is not significant! Let me start out, then, with some questions that I believe are significant, and then try to answer them, in my view. 1) What do we presently believe are the most fundamental assertions of the laws of nature? My answer is: The bases of the quantum theory and the theory of relativity. I am not referring here to mathematical expressions of these theories; I refer to the basic concepts that underlie these expressions. If you do not agree with this answer, or those to the questions below, please respond with your own views.

    Extractions: Foundation of Quantum Theory The following well-known experiments serve as a motivation for studying quantum theory. The experimental results cannot be explained using ideas from classical physics. Blackbody Radiation Photoelectric Effect Compton Effect Blackbody Radiation: It is well-known that when a body is heated it emits electromagnetic radiation. For example, if a piece of iron is heated to a few hundred degrees, it gives off e.m. radiation which is predominantly in the infra-red region. When the temperature is raised to 1000C it will begin to glow with reddish color which means that the radiation emitted by it is in the visible red region having wavelengths shorter than in the previous case. If heated further it will become white-hot and the radiation emitted is shifted towards the still shorter wave-length blue color in the visible spectrum. Thus the nature of the radiation depends on the temperature of the emitter. A heated body not only emits radiation but it also absorbs a part of radiation falling on it. If a body absorbs all the radiant energy falling on it, then its absorptive power is unity. Such a body is called a black body An ideal blackbody is realized in practice by heating to any desired temperature a hollow enclosure (cavity) and with a very small orifice. The inner surface is coated with lamp-black. Thus radiation entering the cavity through the orifice is incident on its blackened inner surface and is partly absorbed and partly reflected. The reflected component is again incident at another point on the inner surface and gets partly absorbed and partly reflected. This process of absorption and reflection continues until the incident beam is totally absorbed by the body.

Quantum theory explains in principle how to calculate what will happen in any experiment involving physical or biological systems, and how to understand how our world works. The name “quantum theory” comes from the fact that the theory describes the matter and energy in the universe in terms of single indivisible units called quanta (singular quantum ). Quantum theory is different from classical physics. Classical physics is an approximation of the set of rules and equations in quantum theory. Classical physics accurately describes the behavior of matter and energy in the everyday universe. For example, classical physics explains the motion of a car accelerating or of a ball flying through the air. Quantum theory, on the other hand, can accurately describe the behavior of the universe on a much smaller scale, that of atoms and smaller particles. The rules of classical physics do not explain the behavior of matter and energy on this small scale. Quantum theory is more general than classical physics, and in principle, it could be used to predict the behavior of any physical, chemical, or biological system. However, explaining the behavior of the everyday world with quantum theory is too complicated to be practical.

    Extractions: 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

About 30% of the world's manufacturing economy is based on the principles of quantum mechanics, one of the most successful theories of physics ever devised and a triumph of human intellectual achievement? The theory says that particles can be in two places at the same time and that measurements we make in one place can have instantaneous effects in another place tens, thousands or even millions of kilometres away? These weird effects have been demonstrated in the laboratory and form the basis of leading-edge research on quantum cryptography, quantum computing, teleportation ("beam me up, Scotty") and time travel? The discoverers of quantum theory - including Albert Einstein and Niels Bohr - argued bitterly about the theory's implications for our understanding of physical reality? These profound questions have led some physicists to think that we live in one of a multitude of parallel universes, or that the mechanics of the physical world are intimately bound up with human consciousness, or quantum weirdness is evidence of divine intervention?

    Extractions: THEORIES WITH PROBLEMS by Keith Mayes Paperback now on sale The Big Bang, Quantum Mechanics, Relativity, Time, Light Speed, Gravity, Electromagnetism, all have their theories that attempt to explain why these things are the way they are. These theories form part of our understanding of the fundamental laws of the universe, but are of course unable to provide all the answers we seek. All theories have problems in that they cannot be proven to be absolutely correct, they do not necessarily accurately describe the way things really are. They are constructed as a working model that is a useful aid to our understanding, of observed phenomenon and as a method of predicting future outcomes. When a theory is found to be wrong, it is either discarded, or as is more generally the case, modified, until it again appears to match the observations. A theory, no matter how well it appears to accurately describe any phenomenon, is provisional, it can never be proven to be completly correct, but it may be proven wrong. It will therefore always be impossible to claim a final theoretical solution to anything. "As being is to becoming, so is truth to belief. If then, Socrates, amid the many opinions about the gods and the generation of the universe, we are not able to give notions which are altogether and in every respect exact and consistent with one another, do not be surprised. Enough if we deduce probabilities as likely as any others; for we must remember that I who am the speaker and you who are the judges are only mortal men". (Plato)

Berkeley, California 94720 Henry Stapp's web site. Responses to this paper. Abstract There are deep similarities between Whitehead's idea of the process by which nature unfolds and the ideas of quantum theory. Whitehead says that the world is made of 'actual occasions', each of which arises from potentialities created by prior actual occasions. These actual occasions are 'happenings' modeled on experiential events, each of which comes into being and then perishes, only to be replaced by a successor. It is these experience-like 'happenings' that are the basic realities of nature, according to Whitehead, not the persisting physical particles that Newtonian physics took be the basic entities. Similarly, Heisenberg says that what is really happening in a quantum process is the emergence of an 'actual' from potentialities created by prior actualities. In the orthodox Copenhagen interpretation of quantum theory the actual things to which the theory refer are increments in 'our knowledge'. These increments are experiential events. The particles of classical physics lose their fundamental status: they dissolve into diffuse clouds of possibilities. At each stage of the unfolding of nature the complete cloud of possibilities acts like the potentiality for the occurrence of a next increment in knowledge, whose occurrence can radically change the cloud of possibilities/potentialities for the still-later increments in knowledge.

"What does not satisfy me, from the standpoint of principle, is (quantum theory's) attitude toward that which appears to be the programmatic aim of all physics: the complete description of any (individual) real situation (as it supposedly exists irrespective of any act of observation or substantiation)"

    Extractions: Previous Next Table of Contents Paul Budnik paul@mtnmath.com Einstein did not believe that God plays dice and thought a more complete theory would predict the actual outcome of experiments. He argued that quantities that are conserved absolutely (such as momentum or energy) must correspond to some objective element of physical reality. Because QM does not model this he felt it must be incomplete. It is possible that events are the result of objective physical processes that we do not yet understand. These processes may determine the actual outcome of experiments and not just their probabilities. Certainly that is the natural assumption to make. Any one who does not understand QM and many who have only a superficial understanding naturally think that observations come about from some objective physical process even if they think we can only predict probabilities. There have been numerous attempts to develop such alternatives. These are often referred to as `hidden variables' theories. Bell proved that such theories cannot deal with quantum entanglement without introducing explicitly nonlocal mechanisms . Quantum entanglement refers to the way observations of two particles are correlated after the particles interact. It comes about because the conservation laws are exact but most observations are probabilistic. Nonlocal operations in hidden variables theories might not seem such a drawback since QM itself must use explicit nonlocal mechanism to deal with entanglement. However in QM the non-locality is in a wave function which most do not consider to be a physical entity. This makes the non-locality less offensive or at least easier to rationalize away.
