Maxwell's equations

Maxwell's equations
Quote So if Coulombs law works best for you, then use coulomb's law - there's no need to re-invent the wheel. As far as the original problem goes it is solved, but it uncovered great many things for me, so what is left now is curiosity because this solution implies Coulomb's and Biot-Savart law tell different and more complete story than Maxwell's equations and yet they are supposed to talk about the same E and B fields. There are two kinds of fields, "radial" like gravity and electric fields, and we have "rotational", like vortexes, whirlpools or magnetic fields. Uniform and constant "radial" field potentials have zero divergence and zero rotation (curl), it's a uniform magnitude distribution and inverse square law which defines topology and geometry of an electric field, not the other way around. This page here shows you how to get coulomb's law from maxwell's first equation: -- This page says: -"Gauss's law can be derived from Coulomb's law Merged post follows: Consecutive posts merged

I was born in the West Midlands in the early Seventies, and worked as an English Teacher for nearly ten years before going part time to study for an MA in Creative Writing at Manchester Metropolitan University. My short stories have been widely published both online and in print, appearing most recently in the pages of Carve, Paraxis, Structo, The Molotov Cocktail, and Fleeting. In January 2013 I received a Carve Esoteric Award for my short story ‘Storm in a Teacup’, while ‘Half-mown Lawn’ won the Yeovil Literary Prize for short fiction and is included in Salt Publishing’s The Best British Short Stories 2012. When not writing, I teach part time, lead writing workshops and take care of my three children.

QM Experiments for Undergraduates Textbook My book is titled Quantum Mechanics: Theory and Experiment, and is written for a junior/senior level quantum mechanics class. It is unique in that it describes not only quantum theory, but also presents laboratories that explore truly modern aspects of quantum mechanics. The book begins the presentation of quantum mechanics using photon polarization as a prototypical two-dimensional quantum system. The Second Law and Energy (second law event) 10/05/2007 1:00 PM Broad InstituteSteven Chu, Secretary of EnergyDescription: This Nobel Prize"winning scientist admits to staying up late the night before his talk to bone up on thermodynamics. He puts his research to good use, discussing the history and application of the laws of thermodynamics, which have served as "the scientific foundation of how we harness energy, and the basis of the industrial revolution, the wealth of nations." Taking Watt's 1765 steam engine, Stephen Chu illustrates basic principles of thermodynamics -- that energy is conserved, that you can do work from heat, especially when you maximize the difference in temperature in the system and minimize heat dissipation from friction. Chu offers another form of the laws: You can't win; you can't break even; and you can't leave the game. The game hasn't changed all that much in the past few centuries. Nations now burn coal for electricity, achieving around 40% thermal efficiency.

Charges and Fields - Electric Charges, Electric Field, Electric Potential Topics Electric Field Electrostatics Equipotential Electrostatic Potential Electric Charges Voltage Description Arrange positive and negative charges in space and view the resulting electric field and electrostatic potential. General relativity General relativity, or the general theory of relativity, is the geometric theory of gravitation published by Albert Einstein in 1916[1] and the current description of gravitation in modern physics. General relativity generalizes special relativity and Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time, or spacetime. In particular, the curvature of spacetime is directly related to the energy and momentum of whatever matter and radiation are present.

Naked Before God – Part 4 – Naked Prayer If meditation can be done in the nude I think we can assume we might as well stay and pray in the nude. The two differ in this: meditation is about listening to God; prayer is about communicating with God. One is about listening; the other is about talking. One other way I have heard it explained is that meditation and petition are the two sides of prayer.

Physics Flash Animations We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. Also included is the minimum version of the Flash player that is required; the player is available free from The categories are: Physics World reveals its top 10 breakthroughs for 2011 The two physics stories that dominated the news in 2011 were questions rather than solid scientific results, namely "Do neutrinos travel faster than light?" and "Has the Higgs boson been found?". However, there have also been some fantastic bona fide research discoveries over the last 12 months, which made it difficult to decide on the Physics World 2011 Breakthrough of the Year.

Nudity and the Roots of Compulsion I have to admit it, there is something that “pulls” at me when it comes to nudity. Yesterday’s post looked at how I entered into the world of naturism as a healing escape from a world that was closing in on me, pushing me into darkness, strangling the will to live at times. As I was reading last night before going to bed, I found these words. I knew immediately that these words would become part of today’s post. Problem of Reciprocity Back to main course page John D. Norton Department of History and Philosophy of Science University of Pittsburgh Gravitational lens A gravitational lens refers to a distribution of matter (such as a cluster of galaxies) between a distant source and an observer, that is capable of bending the light from the source, as it travels towards the observer. This effect is known as gravitational lensing and the amount of bending is one of the predictions of Albert Einstein's general theory of relativity.[1] (Classical physics also predicts bending of light, but only half that of general relativity's.[2]) Although Orest Chwolson (1924) or Frantisek Klin (1936) are sometimes credited as being the first ones to discuss the effect in print, the effect is more commonly associated with Einstein, who published a more famous article on the subject in 1936.
