Chemical Reactions Bonding Crystal Field Theory An ionic theory which is an offshoot of electrostatic theory. It ignores all covalent bonding effects. It was developed by Hans Bethe in 1929 by applying group theory and quantum mechanics to electrostatic theory. It was further developed by physicists during the 1930s and 1940s. It can be used to predict chemical properties, kinetic properties, reaction mechanisms, magnetic and spectral properties, and thermodynamic data. It cannot, however, be applied to sulfides, since sulfide forms mainly covalent bonds A splitting of energy levels ("crystal field splitting") occurs because the orientation of the d orbital wavefunctions will increase an electron's energy when the orbital is located in a region of high electron density, and lower it when the reverse is true. In crystals, the and orbitals split up as depicted below, depending on their cation's coordination. The total energy splitting is termed the crystal field stabilization energy. may be estimated from where r is the radius of the d orbital and R is the metal- ligand internuclear distance. A large crystal field splitting energy is provided by ligands with high negative charge and small radius, and by metal cations with a large oxidation number.

Answer: Albert Einstein coined the term "Unified Field Theory," which describes any attempt to unify the fundamental forces of physics between elementary particles into a single theoretical framework. Einstein spent the latter part of his life searching for such a unified field theory, but was unsuccessful. In the past, seemingly different interaction fields (or "forces," in less precise terms) have been unified together. James Clerk Maxwell successfully unified electricity and magnetism into electromagnetism in the 1800s. The field of quantum electrodynamics, in the 1940s, successfully translated Maxwell's electromagnetism into the terms and mathematics of quantum mechanics.

Corrections to the text may be found here Material Relating to Lectures Will Appear Here Some quotes from lecture 1 We shall be learning a little bit about how to compute Feynman amplitudes via computer programs. As you will soon recognize after calculating a few cross sections, it can be pretty tedious to carry out the trace calculations. In class, we will discuss one Mathematica based program called FeynCalc. You can find a PostScript version of the Users Guide for FeynCalc here. Sections 1 and 2, i.e., pages 1-20 should give you enough information to get started with diagrams that don't have loops.

Back to my home page Einstein's Unified Field Theory with Teleparallelism A translation by A. Unzicker and T. Case Einstein's later later publications have been translated to many languages, but not to English yet (Maybe because there are people who get paid for doing that work slowly). The following translation was performed by Alexander Unzicker and Timothy Case as a voluntary school project of the Pestalozzi-Gymnasium in 2005. Below you find the original and the translation of two reports 'Sitzungsberichte der Preussischen Akademie der Wissenschaften, Mathematisch-Naturwissenschaftliche Klasse', and the paper in 'Mathematische Annalen' that summarizes the content of the reports. We added one precursor report from 1925, which does not deal with teleparallelism explicitly. Since the torsion tensor appears already, this early work may be useful for the historically interested reader. The German original of three later reports are further added. The translated papers are published at the e-print server arxiv.org

50. Relativity And Quantum Theory The most successful numerical approach to quantum field theory begins with a The path integral appropriate for quantum field theory is similar to the http://phys.columbia.edu/~cqft/physics.htm

Combining Relativity and Quantum Theory Overview The two major physics discoveries of the first part of this century, quantum mechanics and Einstein's theory of special relativity present new challenges when treated together. The energy "uncertainty" introduced in quantum theory combines with the mass-energy equivalence of special relativity to allow the creation of particle/anti-particle pairs by quantum fluctuations when the theories are merged. As a result there is no self-consistent theory which generalizes the simple, one-particle Schrödinger equation into a relativistic quantum wave equation. The most successful approach to this problem, developed in the early 30's, begins not with a single relativistic particle, but with a relativistic classical field theory, such as Maxwell's theory of electromagnetism. This classical field theory is then "quantized" in the usual way and the resulting quantum field theory realizes a consistent combination of quantum mechanics and relativity. However, this theory is inherently a many-body theory with the quanta of the normal modes of the classical field having all the properties of physical particles. The resulting many-particle theory can be relatively easily handled if the particles are heavy on the energy scale of interest or if the underlying field theory is essentially linear. Such is the case for atomic physics where the electron-volt energy scale for atomic binding is about a million times smaller than the energy required to create an electron positron pair and where the Maxwell theory of the photon field is essentially linear.

Quantum Field Theory is the tool as well as the language that has been developed to describe the physics of problems in such apparently dissimilar fields. Physics 582 is the first half of a two-semester sequence of courses in Quantum Field Theory. The second half, Physics 583, will be taught in the Spring Semester, 2006. The aim of this sequence is to provide the basic tools of Field Theory to students (both theorists and experimentalists) with a wide range of interests in Physics. These ideas and tools will be used in subsequent and more specialized courses. As a prerequisite I will assume that the students have mastered the contents of the Physics 480/481 sequence on Quantum Mechanics (or equivalent).

These very charged subcurrents are the true sources of the unified field which are included in the right parts of the ML-equations. The reconstruction of both subcurrents as the sources of the unified field and their mathematical and physical properties leans, mainly, on the symmetries of the ML-equations.

59. Toward A Field Theory Of Journalism To search for a field theory of journalism is to search for a theory that explains the entire practice in all of its complexity. http://rhetorica.net/field_theory.htm

Toward a field theory of journalism By Andrew R. Cline, Ph.D. This text was originally published in a series of posts on the Rhetorica: Press-Politics Journal weblog. I have edited it for continuity in this format. To begin understanding the influence of journalism on culture I think it's important to consider the concept of noetic field. A noetic field (as defined by James A. Berlin in Writing Instruction in Nineteenth-Century American Colleges ) is a "closed system defining what can, and cannot, be known; the nature of the knower; the nature of the relationship between the knower, the known, and the audience; and the nature of language." Berlin concludes from this (and I agree) that rhetoric "is thus ultimately implicated in all a society attempts. It is at the center of a culture's activities." At any given time there is a dominant noetic field and, therefore, a dominant rhetoric. I notice that changes in the noetic field can be mapped to changes in writing/rhetoric instruction in American universities (I am not suggesting cause ). I also notice that changes in journalism map to these changes in writing instruction and the noetic field. For example, objectivity as a value in discourse arose in journalism and writing instruction during the same era.
