Ummmm Thanks for the reply tpape... I've been reading this post for the last few months, and I have no clue what this means. Do you know of any resources that could give me some background?

When Empathizing, one puts oneself in another's shoes (colloquially speaking). The magnitude of the wave function corresponding to identical particles is invariant under the exchange operator. This exchange interaction; one might say that identical particles are "empathizing" with one...

Is there any place to put up posts on neural networks? _____________________________________________________ Don't be fooled by the apparent humanity of this poster. He is really a computer pretending to be goat. A very smart goat...

1) The "plot" of a story... A series of events... Normally characterized by "intro", "buildup", "climax", and "conclusion", or whatever other arbitrary label one might fancy to attribute to a section of a piece of literatute... 2) Mathematically, the "plot" of a story is a series of points in...

Anyone out there ever see a theoretical derivation of the local density of states? If so, where?

So if in the reference frame of an object Newtons first law is reformulated as "An object not in motion does not start to spontaneously move" Q: Why should an object not in motion, not start to move? A: If the object did start to move, in which direction would it move?(<- this is a...

I got it backward. How do you the A field from a B field?

How do you get the B field from the magnetic potential? I tried converting the curl into matrix format, but the corresponding matrix can't be inverted.

"An object in motion stays in motion" in the reference frame of the moving object, this statement can be reformulated as "An object not in motion, stays in not motion" Aha! I realize the duck has been slaughtered, and while I'm against curelty to animals, it's really not that cruel to beat...

I always wondered what would happen in such a case. From a classical perspective, I would imagine that the intensity of the field would approach zero as t-> infinity. However, from a quantum perspective, a wave is made up of a finite number of photons; In such a case perhaps the photons...

L =1/2 I w^2 - mgy I is the moment of inertia and w is the angular frequency w =d(theta)/dt and y =r sin(theta) cos could be sin depending where you take your angle. and r is the distance from the fulcrum to the center of mass of the cone. This doesn't include spin motion, and assumes...

And nothing would sustain this Bfield, it would propagate away radially.

There doesn't need to be a current. Just use the wave equation and have this configuration be your initial condition. wave equation is Laplacian[H] - epsilon*mu*SecondDerivate w/ respect to time of H=0 I think the solution for the x component of H is given by Hx = A Sin[Dot[k,r]- wt]...

I was thinking that just like the Gauss's theorem (the surface integral version of the Div[E] = rho/ epsilon) picks out charges which are in effect mathematical singularities, so to the cauchy residue theorem picks out every 1/z of a function. Can this similarity be used to solve...
