Measurement in Quantum Theory
First published Tue Oct 12, 1999; substantive revision Wed Aug 22, 2007 The dynamics and the postulate of collapse are flatly in contradiction with one another ... the postulate of collapse seems to be right about what happens when we make measurements, and the dynamics seems to be bizarrely wrong about what happens when we make measurements, and yet the dynamics seems to be right about what happens whenever we aren't making measurements. (Albert 1992, 79)
1. The Birth of the Measurement Problem
(P) If a quantity Q is measured in system S at time t then Q has a particular value in S at t Many of Bohr's colleagues, including his young protege Werner Heisenberg, misunderstood or rejected the relationalist metaphysics that underpinned Bohr's endorsement of (P). Instead, they favored the positivistic, anti-metaphysical approach expressed in Heisenberg's influential book, The Physical Principles of the Quantum Theory q for S at t unless Q is measured to have value q for S at t Heisenberg's approach, as presented in

What is quantum mechanics? " The quantum is the greatest mystery we've got. Never in my life was I more up a tree than today," John Wheeler. Quantum theory is bizarre. In order to try and understand it we need to forget everything we know about cause and effect, reality, certainty, and much else besides. This is a different world, it has its own rules, rules of probability that make no sense in our everyday world. Richard Feynman, the greatest physicist of his generation, said of quantum theory It is impossible, absolutely impossible to explain it in any classical way'. Quantum theory is much more than just bizarre, it is also without doubt the most amazing theory in existence. If after reading this section you are not totally amazed by it, then the fault will be mine, for I will have failed to reveal to you its deep underlying significance. This theory is not just about experiments and equations, it reveals something extraordinary about our very understanding of what constitutes reality. We will start with the famous double slit experiment as it demonstrates beautifully the central mystery of quantum theory. Quantum theory however, needs some introduction before we get too involved in the experiment.

It is hard to realise that the electron was only discovered a little over 100 years ago in 1897. That it was not expected is illustrated by a remark made by J J Thomson, the discoverer of the electron. He said I was told long afterwards by a distinguished physicist who had been present at my lecture that he thought I had been pulling their leg. The neutron was not discovered until 1932 so it is against this background that we trace the beginnings of quantum theory back to 1859. In 1859 Gustav Kirchhoff proved a theorem about blackbody radiation. A blackbody is an object that absorbs all the energy that falls upon it and, because it reflects no light, it would appear black to an observer. A blackbody is also a perfect emitter and Kirchhoff proved that the energy emitted E depends only on the temperature T and the frequency v of the emitted energy, i.e. E J T v He challenged physicists to find the function J In 1879 Josef Stefan proposed, on experimental grounds, that the total energy emitted by a hot body was proportional to the fourth power of the temperature. In the generality stated by

What is Quantum Physics?
Quantum physics is a branch of science that deals with discrete, indivisible units of energy called quanta as described by the Quantum Theory. There are five main ideas represented in Quantum Theory:
  • Energy is not continuous, but comes in small but discrete units.
  • The elementary particles behave both like particles and like waves.
  • The movement of these particles is inherently random.
  • It is physically impossible to know both the position and the momentum of a particle at the same time. The more precisely one is known, the less precise the measurement of the other is.
  • The atomic world is nothing like the world we live in. While at a glance this may seem like just another strange theory, it contains many clues as to the fundamental nature of the universe and is more important then even relativity in the grand scheme of things (if any one thing at that level could be said to be more important then anything else). Furthermore, it describes the nature of the universe as being much different then the world we see. As Niels Bohr said, "Anyone who is not shocked by quantum theory has not understood it."
    Particle/Wave Duality
    Particle/wave duality is perhaps the easiest way to get aquatinted with quantum theory because it shows, in a few simple experiments, how different the atomic world is from our world.

We have been told that experiments agree with all the predictions of quantum theory, including those that involve the impossible - the Bell test experiments , that are supposed to show totally incomprehensible effects of separated particles on each other. I have looked at the evidence. The "loopholes" that they know are present are large enough to allow for perfectly straightforward explanations, with no sign of "non-locality". I am led to suggest that perhaps there is other currently-accepted "evidence" for both quantum theory and Einstein's relativity theories that needs re-investigation. (There is! See

    Quantum Theory and Wave/Particle Duality
    A work in Progress; modified: 7-March-2001
    Many interpretations of quantum physics incorporate the idea that particles (or some property associated with particles) propagate as waves.
    The object of this article is to examine the core assumptions behind this wave/particle idea with a view to developing a different model that is consistent with relativity, observation and the mathematical formalism.

      Essentially, wave/particle duality employs the notion that an entity simultaneously possesses localized (particle) and distributed (wave) properties. The idea has been introduced into modern physics to account for observations in which particles of matter interact to produce effects that appear to be identical to the effects that occur when waves diffract and interfere. However, the concept of rests on an assumption. It is assumed that wave propagation mechanisms can provide the only possible explanation for scattering effects observed in experiments such as the Twin Slit experiment.

    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.

    79. Dr. Mendel Sachs
    On compatibility of the quantum theory and theory of general relativity - by Dr. Mendel Sachs.
    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.

Given by Professor Bethe at age 93, the lectures are presented here as QuickTime videos synchronized with slides of his talking points and archival material. Intended for an audience of Professor Bethe's neighbors at Kendal, the lectures hold appeal for experts and non-experts alike. The presentation makes use of limited mathematics while focusing on the personal and historical perspectives of one of the principal architects of quantum theory whose career in physics spans 75 years.
