Maxwell's equations: meaning, derivation and applicability - Classical Physics

Maxwell's equations: meaning, derivation and applicability - Classical Physics
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 Related:  physicsPhysics Course Materials

About | Dan Powell Hello! I’m Dan Powell, an award winning writer of short-fiction. 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. My debut collection of short fiction, Looking Out of Broken Windows, was shortlisted for the 2013 Scott Prize and will be published by Salt in March 2014.

10 Strange Things About The Universe Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ? One of the properties of a negative-energy vacuum is that light actually travels faster in it than it does in a normal vacuum, something that may one day allow people to travel faster than the speed of light in a kind of negative-energy vacuum bubble. One prediction of Einstein’s theory of general relativity is that when a large object moves, it drags the space-time around it, causing nearby objects to be pulled along as well. Relativity of Simultaneity Since this extra dimension is so small, only tiny objects, such as particles, can move along it. Antimatter Retrocausality

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. credit MIT World -- special events and lectures license MIT TechTV

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. Description Technology has advanced to the point where truly modern experiments which explore the fundamentals of quantum mechanics are accessible to undergraduates. Overview · Slides of a talk given at Amherst College in Oct. 2004. · Slides of a talk given at AAPT Meeting, July 2006. · Slides of a talk given at AAPT Meeting, July 2006. Experiments Proof of the Existence of Photons (the Grangier Experiment) This experiment duplicates the experiment of Grangier, Roger and Aspect [1], in which they demonstrate that if a single photon is incident on a beamsplitter, it can only be detected at one of the outputs (not both.)

San Diego Tantra Community Calendar (San Diego, CA Please join us for Movie Night and Potluck. Potluck 6 - 7 pm. Movie & discussion 7 - 9:30 pm. The idea is that each month we present a different sexy, thought provoking, inspiring movie or film. Our movie of the month will be "SEXUAL HEALING ~ The Tantra Way", followed by an open discussion. This film is only 1 hour long, so there will be plenty of time for discussion. I am NOT charging a set fee for this event. BTW... same old location... Charles Muir is a delightful and inspiring teacher and healer!!! Recently I went to one of Charles Muir's lecture and puja events, and I won this DVD in a drawing, so I think the Universe dropped it in my lap so that I could share it with all of you in this group. Synopsis: This educational, profound and often humorous DVD presents renowned Tantra Master, Charles Muir (along with a panel of other presenters) addressing over 100 of the world's leading Tantra educators and sexual healers.

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. The relation is specified by the Einstein field equations, a system of partial differential equations. Some predictions of general relativity differ significantly from those of classical physics, especially concerning the passage of time, the geometry of space, the motion of bodies in free fall, and the propagation of light. Einstein's theory has important astrophysical implications. History[edit] Albert Einstein developed the theories of special and general relativity.
