Oct 15, 2010 09:27 I was sitting in the other room working when I heard the netball on the television. Amy had flicked over during Project Runway (I love that show) and was suddenly enthralled by what may have been the most tense game we have ever watched. I kept typing with the TV audio enough to keep me hooked as did the Twitter updates streaming through that were mainly made up of swearing, groans and score updates. The swearing was mainly aimed at the referees who seemed to a vague understanding of how the rules went and were just kind of winging it. Thankfully their odd calls went in both directions and I thought the commentators did admirably to keep their own swearing in their heads. I was devastated.

Pich (Submitted on 8 Jun 1998) Abstract: These lectures provide an introduction to the basic ideas and methods of Effective Field Theory, and a description of a few interesting phenomenological applications in particle physics. The main conceptual foundations are discussed in sections 2 and 3, which cover the momentum expansion and the most important issues associated with the renormalization process. Section 4 presents an overview of Chiral Perturbation Theory, the low-energy realization of Quantum Chromodynamics in the light quark sector. The Chiral Perturbation Theory framework is applied to weak transitions in section 5, where the physics of non-leptonic kaon decays is analyzed. The so-called Heavy Quark Effective Theory is briefly discussed in section 6. The electroweak chiral Effective Field Theory is described in section 7, which contains a brief overview of the effective Lagrangian associated with the spontaneous electroweak symmetry breaking. Some summarizing comments are finally given in section 8. Comments: 106 pages, 20 figures. Lectures at the 1997 Les Houches Summer School "Probing the Standard Model of Particle Interactions"

Some physicists believe string theory may unify the forces of nature by Brian Greene The Elegant Universe homepage Note: For a definition of unfamiliar terms, see our glossary loop . Like an infinitely thin rubber band, each particle contains a vibrating, oscillating, dancing filament that physicists have named a string In the figure at right, we illustrate this essential idea of string theory by starting with an ordinary piece of matter, an apple, and repeatedly magnifying its structure to reveal its ingredients on ever smaller scales. String theory adds the new microscopic layer of a vibrating loop to the previously known progression from atoms through protons, neutrons, electrons, and quarks. Although it is by no means obvious, this simple replacement of point-particle material constituents with strings resolves the incompatibility between quantum mechanics and general relativity (which, as currently formulated, cannot both be right ). String theory thereby unravels the central Gordian knot of contemporary theoretical physics. This is a tremendous achievement, but it is only part of the reason string theory has generated such excitement.

The reviews on Amazon.com are also worth reading. Overview An Introduction to Quantum Field Theory is a textbook intended for the graduate course covering relativistic quantum mechanics, quantum electrodynamics, and Feynman diagrams. The authors make this subject accessible through carefully worked examples illustrating the technical aspects of the subject, and intuitive explanations of what is going on behind the mathematics. After presenting the basics of quantum electrodynamics, the authors discuss the theory of renormalization and its relation to statistical mechanics, and introduce the renormalization group. This discussion sets the stage for a treatment of non-Abelian gauge theories and their use in describing the fundamental interactions of elementary particles.

77. The Casimir Effect What is the Casimir Effect? From the Usenet FAQ. http://www.math.ucr.edu/home/baez/physics/Quantum/casimir.html

[Physics FAQ] Calculation by Don Koks, 2002 Original by Philip Gibbs, 1997 What is the Casimir Effect? The Casimir effect is a small attractive force that acts between two close parallel uncharged conducting plates. It is due to quantum vacuum fluctuations of the electromagnetic field. The effect was predicted by the Dutch physicist Hendrick Casimir in 1948. According to the quantum theory, the vacuum contains virtual particles which are in a continuous state of fluctuation (see physics FAQ article on virtual particles ). Casimir realised that between two plates, only those virtual photons whose wavelengths fit a whole number of times into the gap should be counted when calculating the vacuum energy. The energy density decreases as the plates are moved closer, which implies that there is a small force drawing them together. The attractive Casimir force between two plates of area A separated by a distance L can be calculated to be, where h is Planck's constant and c is the speed of light. The tiny force was measured in 1996 by Steven Lamoreaux. His results were in agreement with the theory to within the experimental uncertainty of 5%. Particles other than the photon also contribute a small effect but only the photon force is measurable. All bosons such as photons produce an attractive Casimir force while fermions make a repulsive contribution. If electromagnetism was supersymmetric there would be fermionic photinos whose contribution would exactly cancel that of the photons and there would be no Casimir effect. The fact that the Casimir effect exists shows that if supersymmetry exists in nature it must be a broken symmetry

Subscribe Give a Gift Archives Customer Service SEARCH Technology Space Human Origins Living World ... Telekinesis and Quantum Field Theory by Sean Parapsychological Association , it seems worth spelling out in detail the claim that parapsychological phenomena are inconsistent with the known laws of physics. The main point here is that, while there are certainly many things that modern science does not understand, there are also many things that it does understand, and those things simply do not allow for telekinesis, telepathy, etc. Which is not to say that we can prove science never proves anything The crucial concept here is that, in the modern framework of fundamental physics, not only do we know certain things, but we have a very precise understanding of the limits of our reliable knowledge Parameterized Post-Newtonian formalism . There is a denumerable set of ways in which the motion of test particles can deviate from Newtonian gravity (as well as from general relativity), and we can tell you what the limits are on each of them. At small distances, the inverse-square behavior of the gravitational force law can certainly break down; but we can tell you exactly the scale above which it will not break down dark matter is understandably not nearly as good.

Bookmark what is this? High Energy Physics - Phenomenology Title: Introduction to Gauge Theories Authors: C. Becchi (Submitted on 2 May 1997) Abstract: These lectures present an elementary introduction to quantum gauge fields. The first aim is to show how, in the tree approximation, gauge invariance follows from covariance and unitarity. This leads to the standard construction of the Lagrangian by means of covariant derivatives in a form that unifies the massive and the massless case. Having so identified the classical theory, the Faddeev-Popov quantization method is introduced and the BRS invariance of the resulting action is discussed.

Levin (Submitted on 31 Aug 1998) Abstract: This talk is an attempt to clarify for experimentalists what we (theorists) mean when we are saying "Pomeron". I hope, that in this talk they will find answers to such questions as what is Pomeron, what we have learned about Pomeron, both experimentally and theoretically, what is correct strategy to study Pomeron experimentally and etc. I also hope that this talk could be used as a guide in the zoo of Pomerons: "soft" Pomeron, "hard" Pomeron, the BFKL Pomeron, the Donnachie-Landshoff Pomeron and so on. The large number of different Pomerons just reflects our poor understanding of high energy asymptotics in out microscopic theory -QCD. The motto of my talk, which gives you my opinion on the subject in short is:``Pomeron is still unknown but needed for 25 year to describe experimental data".
