In my world, EMF stands for, one of those “Electronic Mother Fuckers.” I know, foul language and all. I’ve used it. I am not ashamed. I am trying to get it out now, before the Pirate Twins begin to repeat any more colorful language. It just seems a term that should be used when one forgets the name of something. “Hey, Mary, can you grab that thing over there?” “Sure Pete, but what is it?” “You know, it’s one of them electronic mother fuckers.”

Now you can not only buy an EMF detector, but protect your pets from harmful EMFs as well (and, it appears, make them walk around and detect EMFs for you)…snicker, snicker, snort. I don’t think dogs appreciate this sort of treatment.
I am fully aware that I am lying to myself by saying that Wednesday nights are for ironing, and as I get bored just looking at the extra wrinkles I am adding to clothes, I need something to infiltrate my mind-space, and take over for a little while. Though I suppose it is partially true, it is really a coverup for my guilty indulgence of the stoopidity that is Ghost Hunters. I need to tell myself a lie to feel better about watching it. The whole truth, is plainly this: I love the feeling of intellectual superiority that it gives me, and I love figuring out the puzzle/illusion on my own. I relish their misuse/mangling of the English language. I cannot imagine a week without their faulty theories and inconsistent beliefs. I love to hear them describe air as a “black mass,” which apparently is the only definition of this term they have ever heard/used. It means something quite different to me…and it seems rather unusual, though air indeed has mass, to use the word to describe a shadow. Shadow mass…so what does a shadow weigh?

It is often assumed, when interpreting the discrete trajectory computed by a symplectic numerical integrator of Hamilton’s equations in Cartesian coordinates, that velocity is equal to the momentum divided by the physical mass. However, the “shadow Hamiltonian” which is almost exactly solved by the symplectic integrator will, in general, induce a nonlinear relationship between velocity and momentum. For the (symplectic) momentum- and midpoint-momentum-Verlet algorithms, the “shadow mass” that relates velocity and momentum is momentum independent only for a quadratic potential and, even in this case, differs from the physical mass. Thus, naively assuming the standard velocity-momentum relationship leads to inconsistencies and unnecessarily inaccurate estimates of velocity-dependent quantities. As examples, we calculate the shadow Hamiltonians for the momentum- and midpoint-momentum-Verlet solutions of the multidimensional harmonic oscillator, and show how their velocity-momentum relationships depend on the time step. Of practical importance is the conclusion that, to gain the full advantage of symplecticity, velocities derived from interpolated positions, rather than conventional velocity-Verlet velocities, should be used to compute physical properties.
I really need to find out more about Hamiltonians and Verlets (though I badly want the word to be “varlet”)! See, the physicists know what’s up. Frankly, I think I am stunned to find that a shadow indeed may have mass. Not sure just yet…need to ask the Ungulate.
Frankly, I like AnnaKate’s theory that the ghosts we see are really just people living in another dimension that happens to be just a couple of feet up and a couple of feet to the left of our own.
Hey! That’s an awesome name, actually…”Shadow Hamilton”… I now have a new character’s story to write…which I really don’t need right now. So, maybe some musically inclined physicist should form a band called, “Shadow Hamilton and the Verlets.”
Right, back to the scads of pieces I should be working on rather than writing my thought train out here… Can one train thought? I need a thought trainer. Or ADD medication.
Hoping everyone’s EMFs are running well this week,

Less commonly known as: Drosophilia melanogaster; More commonly known as: “fruit-flies,” and still more commonly known (in my home, anyway), as “Those red-eyed suck-bastards!” They have invaded, hitching a ride on a banana, and quickly expanding their universe to include the entire house. They make me seethe with anger and a will toward splattery vengeance for their rude and horrible intrusion!
