62. THE COPENHAGEN INTERPRETATION OF QUANTUM MECHANICS The more classical view was his statistical interpretation of quantum mechanics. In this interpretation, a particle may possess a definite position and http://www.benbest.com/science/quantum.html

The Copenhagen Interpretation of Quantum Mechanics by Ben Best Near the end of the nineteenth century many physicists believed that physical theory had been virtually completely discovered. Lord Kelvin expressed this view, with the qualifier that "two small clouds" remained on the horizon: (1) the negative results of the Michaelson-Morley experiment and (2) the failure of the Rayleigh-Jeans law to predict the distribution of radiant energy in a black body. These "small clouds" were soon unleashing the thunderstorms of relativity and quantum theory. Thirty years later, however, some leading physicists were again attempting to declare the end of physical knowledge. This time, however, the claim was not so much that physics had the means of explaining all phenomena, but that physics had reached the limits of its capacity to explain. The search for causal laws was declared fruitless because of the claim that the threshold of acausal randomness had been discovered with the further implication that there is ultimately no objective reality. This is the philosophical essence of the Copenhagen Interpretation of quantum theory. And it is an interpretation which does not follow strictly from physics. The Copenhagen Interpretation was primarily the product of Neils Bohr and Werner Heisenberg, who were strongly supported by Max Born, Wolfgang Pauli and John von Neumann. Among those opposed to the Copenhagen Interpretation have been Albert Einstein, Erwin Schroedinger, Louis de Broglie, Max Planck, David Bohm, Alfred Landé, Karl Popper and Bertrand Russell. While those supporting the Copenhagen Interpretation constitute a "school" and an "orthodoxy", those opposed to it have widely divergent views. But the latter have been uniformly vilified as too simple-minded or too "old fashioned" to understand such "modern" ideas as acausality and positivism. Soviet physicists also opposed the Copenhagen Interpretation, but on the grounds that it is an "idealism", to be contrasted to a "dialectical materialist" view of reality.

Thall's History of Quantum Mechanics The development of quantum mechanics was perhaps the greatest intellectual achievement of the 20th century. While many individuals made contributions, twelve are highlighted in this abbreviated history. Sir William Hamilton (1805-1865) Hamiltonian Function Had Hamilton, often considered the "forgotten founder" of quantum mechanics, been around in the 1920's, he surely would have seen the connection between matrix mechanics and wave mechanics. The Hamiltonian function (1835) expresses rate of change in time for a set of moving particles. It specifies total energy particles. Hamiltonians are a method for finding the minimum value of a given equation and are used to calculate the path of least action such as orbits and trajectories. Hamilton's unification of dynamics and optics has had a lasting influence on mathematical physics, even though the full significance of his work was not fully appreciated until after the rise of quantum mechanics. David Hilbert (1862-1943) Hilbert Space David Hilbert was one of the outstanding mathematicians of the modern era. He proposed 21

65. A Brief History Of Quantum Mechanics Thus a full history of quantum mechanics would have to discuss Schrödinger s many mistresses, Ehrenfest s suicide, and Heisenberg s involvement with Nazism. http://www.oberlin.edu/physics/dstyer/StrangeQM/history.html

A Brief History of Quantum Mechanics Appendix A of The Strange World of Quantum Mechanics This World Wide Web page written by Dan Styer Oberlin College Physics Department http://www.oberlin.edu/physics/dstyer/StrangeQM/history.html; Up to now this book has focused on the behavior of nature. I could say more: more about measurement, more about the classical limit, more about different rules for assigning amplitudes, and so forth, but the main points have been made. So instead of talking more about nature I'm going to talk about people about how people discovered quantum mechanics. Warnings Because I find the sugar-sweet stories of the harmonious development of science to be so offensive, when I tell the story I emphasize the conflicts, the contingencies, and the unpredictablities. Hence the story I tell is no more accurate than the sweet talk, because I go too far in the opposite direction. Keep in mind, as you read the story that follows, that I suffer from this overreaction as well as all the other difficulties mentioned in this section. Status of physics: January 1900 In January 1900 the atomic hypothesis was widely but not universally accepted. Atoms were considered point particles, and it wasn't clear how atoms of different elements differed. The electron had just been discovered (1897) and it wasn't clear where (or even whether) electrons were located within atoms. One important outstanding problem concerned the colors emitted by atoms in a discharge tube (familiar today as the light from a fluorescent tube or from a neon sign). No one could understand why different gas atoms glowed in different colors. Another outstanding problem concerned the amount of heat required to change the temperature of a diatomic gas such as oxygen: the measured amounts were well below the value predicted by theory. Because quantum mechanics is important when applied to atomic phenomena, you might guess that investigations into questions like these would give rise to the discovery of quantum mechanics. Instead it came from a study of heat radiation.

How, then, to explain the Grand Canyon-sized gap between what users really want and what we so often produce as a direct result of our sincere listening? Maybe the physics is wrong... Light can behave as a wave, until you ask it to explain how it got from point A to point B, in which case it can behave as a particle. In other words, asking light to explain itself can change the very nature of how we perceive it. And this notion that sometimes observing an event changes the event" comes up in many areas of quantum physics.

69. Relativity/Quantum Mechanics Resolution of the Relativity/quantum mechanics Conflict . I hold that this is the exact source of the conflict between Relativity and quantum mechanics. http://home.jam.rr.com/dicksfiles/flaw/Fatalfla.htm

Resolution of the Relativity/Quantum Mechanics Conflict By Richard D. Stafford, Ph.D. "There is a deep seated fundamental conflict between Quantum theory and Einstein's theory of relativity. Subtle difficulties become insurmountable problems when gravity is added I believe there exists a fundamental error in the common perception of reality: I hold that this error is the basis of the conflict decried above. In a nutshell, the error concerns our confused concept of time. Every student has been told countless times that Newton’s error (which stood for almost 300 years) was that he assumed everyone’s clock could be set to read the same. In the same vein, I hold that Einstein’s error (an error which has plagued science for almost 100 years already) was that he assumed clocks measured time. It is my position that this perception so blocked his view (as even today it blocks the view of the whole scientific community) that he made a mistake in his fundamental view of the problem one would not expect of a high school science student much less a trained scientist. If you are going to take the position that to criticize Einstein or his work is beyond the right of a mere mortal, read no further as this message is not for you; however, if you have the mental capability to temporarily suspend judgment and are willing to look at a possible alternative, please read on. If you closely examine my arguments, you may be surprised by what you find. It is my claim that the most important problem in modern physics is a subtly confused concept of time. Please note that I am making no argument here against any of the experimental results which are used to defend Einstein; the argument is wholly with the interpretation of those results.

A Neighborhood of Infinity Tuesday, March 06, 2007 Monads, Vector Spaces and Quantum Mechanics pt. II Back from wordpress.com: I had originally intended to write some code to simulate quantum computers and implement some quantum algorithms. I'll probably eventually do that but today I just want to look at quantum mechanics in its own right as a kind of generalisation of probability. This is probably going to be the most incomprehensible post I've written in this blog. On the other hand, even though I eventually talk about the philosophy of quantum mechanics, there's some Haskell code to play with at every stage, and the codeives the same results as appear in physics papers, so maybe that will help give a handle on what I'm saying. First get some Haskell fluff out of the way: Now define certain types of vector spaces. The idea is the a W b a is a vector in a space whose basis elements are labelled by objects of type a and where the coefficients are of type p This is very similar to standard probability monads except that I've allowed the probabilities to be types other than Float . Now we need a couple of ways to operate on these vectors. mapW allows the application of a function transforming the probabilities...

Publications in Physics and Mathematics by Walter Pfeifer Order for free Reader's comments Table of Contents Description ... Contact Relativistic Quantum Mechanics, an Introduction 73 pages, 1 line figure, 2004 Relativistic quantum mechanics This book deals mainly with the Dirac equation, its properties, its applications and its limiting cases. A formalism for particles with arbitrary spin and remarks on other relativistic quantum mechanical equations are given. This publication is an introduction and is directed towards students of physics and interested physicists. The detailed developments and the numerous references to preceding places make it easier to follow. However, knowledge of the elements of quantum mechanics, relativistic mechanics and electrodynamics is a prerequisite. In order to relieve the reader, we don't deal with rotations of the coordinate system and not with Lorentz groups either. We have no renaming of matrices, no Feynman daggers, no Einstein convention of summation over repeated indices, no quantum field theory, no second quantisation and no natural units with h'=c=1. From the contents : The Lorentz transformation, quantum mechanical operators, the Dirac equation, probability density, nonrelativistic limits of the Dirac equation, anomalous magnetic moment, free particle, cyclotron motion, parity, total angular momentum, Dirac particle in a Coulomb field, massless particles, particles with arbitrary spin, charge conjugation, the Klein-Gordon equation. The complete list is available via the Table of contents link.

(issue of May 1935) Title and Authors 23 September 2005 What's Wrong with Quantum Mechanics? P. Ehrenfest, courtesy Quantum Opponents. In 1935 Albert Einstein and two colleagues published an attack on the new quantum mechanics, saying that it led to contradictions. Niels Bohr (left) defended the theory. In honor of the World Year of Physics , which commemorates Einstein's "miraculous year" in 1905, we're presenting papers from the Physical Review archive related to Einstein's accomplishments. Albert Einstein never really liked quantum mechanics. In 1935, he and two colleagues argued in the Physical Review that the theory was missing something essential. They described an imaginary experiment in which measurements of one particle revealed information about another particle without measuring the second one directly. They claimed that the possibility of such an experiment contradicted a basic tenet of standard quantum theory. Although the argument was essentially disproved later, it still leaves difficult questions unresolved, if largely ignored, by most working physicists. Before the 1920s, physicists took it for granted that physical objects possess definite properties that suitable observations can reveal. But according to quantum principles, a measurement of some propertya particle's momentum, saycan yield a range of possible results with varying probabilities.
