Book Description
This volume provides a useful introduction to the helicity method, summarizing over ten years of research on the subject. The book requires only some familiarity with Feynman diagrams and Dirac algebra, and many examples are included to clarify the textual material. The reader will find the extensive listing of helicity amplitudes and cross-sections for many of the most important QED and QCD processes at high energies, many not found in the literature previously, particularly useful.

Book Description
The mechanism accelerating Cosmic rays in the milky way galaxy and galaxy clusters is identified and described. The acceleration of Cosmic rays is a purely electrostatic process which operate up to the maximum energies of 1023 ev in galaxy clusters. Galactic Cosmic rays are accelerated in a pervasive electrostatic field active in the whole galaxy except in restricted regions shielded by Interstellar and stellar plasma as, for instance, the region occupied by the Solar system. It is proved that the Energy spectrum of the Cosmic radiation in the milky way galaxy, in the region where the Solar system resides, has a constant Spectral index comprised between 2.64-2.68 and the maximum energies of galactic protons are 3.0 × 1019 ev. The agreement of these results with the experimental data is discussed in detail and highlighted. The various physical processes that maintain the stability of the electrostatic structure in the milky way galaxy are the same that generate the galactic magnetic field. Accordingly, the intensity, orientation and direction of the galactic magnetic field are evaluated. The results of the calculation are compared with the observation data, optical and mostly radio astronomi data. The accord of the intensity, orientation and direction of the observed magnetic field with calculation is excellent.

Book Description
The main focus of this book is on experimental results from electron-positron and electron-proton colliders and related theoretical questions, particularly on hadron production at energies from 1 to 100 GeV and higher. The topics discussed include photo- and electroproduction of heavy flavours, the photon structure function, total cross section, jet production and resonance production. The future of the field is also discussed, notably experiments at linear photon-photon colliders.

Book Description
Lange has recently returned from a tour of duty with an oil exploration and pipeline company in the Near East. He had been incarcerated in an Arab jail for a number of months under almost inhumane conditions. Wrongly. While in the Arabian jail, to preserve his sanity, Lange had developed the ability to induce OOBE's. He didn't understand what was happening to him, he thought they were merely hallucinations. The setting is the Gulf Coast of Mississippi in the late 1980's when the U.S. oil giants had pulled out of the Arabian Gulf area. He was now back in the States looking for a job. Rhyme, a lovely young woman, is the ward and 'strong right arm' of George Westwood, an entrepreneur involved with the development of a fabulous new technology that turns out to be a system of communication with other time frames. Rhyme hires Lange and is attracted to him in spite of the differences in their ages. She is a student of the occult and lays the Tarot cards about Lange. They promise her 'Happiness and Joy'. Rhyme seduces Lange and decides he is her soul mate. She learns that Lange can achieve these conditions. They work on it together, very successfully. On their next attempt they visit an 'Orientation Platform' in the Astral World where they meet with Rhyme's grandmother, Cynthia, who, before her death, had been a major factor in Rhyme's early life. Rhyme's mother had died at childbirth. Lange moves in with Rhyme. There are a number of excursions into the Astral realms. On two they are given rides in a UFO. The first of these is an excursion into the adjoining territories of 'Athe'. On another occasion they take a friend along and they are given a tour of the two lover levels. The 'Orientation' is on the 'third level'. We have here a pretty good guide to achieving the same results (OOBE's) by your own efforts, if you care to try these tenets and the story does not deviate for their principles.

Book Description
"Speculation is rife that by 2012 the elusive Higgs boson will be found at the Large Hadron Collider. If found, the Higgs boson would help explain why everything has mass. But there's more at stake-what we're really testing is our capacity to make the universe reasonable. Our best understanding of physics is predicated on something known as quantum field theory. Unfortunately, in its raw form, it doesn't make sense-its outputs are physically impossible infinite percentages when they should be something simpler, like the number 1. The kind of physics that the Higgs boson represents seeks to "renormalize" field theory, forcing equations to provide answers that match what we see in the real world. The Infinity Puzzle is the story of a wild idea on the road to acceptance. Only Close can tell it"--

Book Description
This volume, marking the 20th Anniversary of the International School of Cosmic Ray Astrophysics, provides a wide-ranging overview of modern astrophysics — from the infra-red to X-rays and γ-rays, from neutrinos to galactic cosmic rays, and from shock wave acceleration to cosmology. The separate topics contain both background information and the newest results in the field, making the discussion suitable for the nonexpert and the expert alike. Featured are high energy neutrinos (including the new generation of experiments coming on line), new results from X-ray astronomy and from the infra-red, particle acceleration in astrophysical plasmas, new results on the composition of cosmic rays (spanning six decades in energy), and cosmology.
