Field of a quadrupole



http://en.wikipedia.org/wiki/Quadrupole

All known magnetic sources give dipole fields. However, to make a magnetic quadrupole it is possible to place four identical bar magnets perpendicular to each other such that the north pole of one is next to the south of the other. Such a configuration cancels the dipole moment and gives a quadrupole moment, and its field will decrease at large distances faster than that of a dipole.
An example of a magnetic quadrupole, involving permanent magnets, is depicted on the right. Electromagnets of similar conceptual design (called quadrupole magnets) are commonly used to focus beams of charged particles in particle accelerators and beam transport lines, a method known as strong focusing. The quadrupole-dipole intersect can be found by multiplying the spin of the unpaired nucleon by its parent atom. There are four steel pole tips, two opposing magnetic north poles and two opposing magnetic south poles. The steel is magnetized by a large electric current that flows in the coils of tubing wrapped around the poles.

http://en.wikipedia.org/wiki/Dipolar_theism In process theology dipolar theism is the position that in order to conceive a perfect God, one must conceive It as embodying the "good" in sometimes-opposing characteristics, and therefore cannot be understood to embody only one set of characteristics.

In physics, there are several kinds of dipoles:
  • An electric dipole is a separation of positive and negative charges. The simplest example of this is a pair of electric charges of equal magnitude but opposite sign, separated by some (usually small) distance. A permanent electric dipole is called an electret.
  • A magnetic dipole is a closed circulation of electric current. A simple example of this is a single loop of wire with some constant current flowing through it.[1][2]
  • A flow dipole is a separation of a sink and a source. In a highly viscous medium, a two-beater kitchen mixer causes a dipole flow field.
  • An acoustic dipole is the oscillating version of it. A simple example is a dipole speaker.
  • Any scalar or other field may have a dipole moment.
Dipoles can be characterized by their dipole moment, a vector quantity. For the simple electric dipole given above, the electric dipole moment points from the negative charge towards the positive charge, and has a magnitude equal to the strength of each charge times the separation between the charges. (To be precise: for the definition of the dipole moment one should always consider the "dipole limit", where e.g. the distance of the generating charges should converge to 0, while simultaneously the charge strength should diverge to infinity in such a way that the product remains a positive constant.)
In addition to current loops, the electron, among other fundamental particles, has a magnetic dipole moment. This is because it generates a magnetic field that is identical to that generated by a very small current loop. However, to the best of our knowledge, the electron's magnetic moment is not due to a current loop, but is instead an intrinsic property of the electron. It is also possible that the electron has an electric dipole moment, although this has not yet been observed (see electron electric dipole moment for more information).
The only known mechanisms for the creation of magnetic dipoles are by current loops or quantum-mechanical spin since the existence of magnetic monopoles has never been experimentally demonstrated.
 With respect to molecules, there are three types of dipoles:
  • Permanent dipoles: These occur when two atoms in a molecule have substantially different electronegativity: One atom attracts electrons more than another, becoming more negative, while the other atom becomes more positive. See dipole-dipole attractions.
  • Instantaneous dipoles: These occur due to chance when electrons happen to be more concentrated in one place than another in a molecule, creating a temporary dipole. See instantaneous dipole.
  • Induced dipoles: These can occur when one molecule with a permanent dipole repels another molecule's electrons, "inducing" a dipole moment in that molecule. See induced-dipole attraction.

KALASH: (Express Tribune) “We are a very strange people and this is why you are here,” Engineer Khan told a small group of primarily Pakistani tourists and journalists at the Kalash Home Guest House, which he and his family operate in the village of Rumbur.
The Kalash, are indigenous people residing in the Chitral District of Khyber-Pakhtunkhwa province of Pakistan.

Neurons are only capable of communicating in one of two ways, either by firing or by not firing. This is very similar to the 1 (fire) and 0 (don't fire) familiar to binary code. Any time the brain sends information, a series of related neurons fire, while those unrelated do not. The central nervous system receives the commands and relays them to perform the appropriate function.
My view of the world around me is drastically varied based on my unique place in the universe in comparison to others. The experience of consciousness also changes based on the neurological network in an individual's brain. Since all of our brains are "wired" differently, our perception of the world around us is different.
External forces can play a huge part of what shapes our view of the world.
"Reality" is not a constant, as the processors of "reality" (our brains) vary according to circumstance.
At what point is this data being shredded and pieced together if there is nothing to be rearranged?
data is constantly being sent and received throughout the body, with some of this information not being processed as intended. Such a genetically programmed misinterpretation of data could be the source of all neurological disorders, as the "message" received will never be the "message" sent.

Have you ever wondered why there are two halves to the brain? Children with one malformed brain hemisphere, live a normal life when surgeons remove the defective half of the brain. Also, in cases of severe schizophrenia, the connection between the two hemispheres of the brain is severed and they are separated so that they don't "think together." This is a form of cure for schizophrenia.

Duke Mu of Chin said to Po Lo: "You are now advanced in years. Is there any member of your family whom I could employ to look for horses in your stead?" Po Lo replied: "A good horse can be picked out by its general build and appearance. But the superlative horse — one that raises no dust and leaves no tracks — is something evanescent and fleeting, elusive as thin air. The talents of my sons lie on a lower plane altogether; they can tell a good horse when they see one, but they cannot tell a superlative horse. I have a friend, however, one Chiu-fang Kao, a hawker of fuel and vegetables, who in things appertaining to horses is nowise my inferior. Pray see him." Duke Mu did so, and subsequently dispatched him on the quest for a steed. Three months later, he returned with the news that he had found one. "It is now in Shach'iu" he added. "What kind of a horse is it?" asked the Duke. "Oh, it is a dun-colored mare," was the reply. However, someone being sent to fetch it, the animal turned out to be a coal-black stallion! Much displeased, the Duke sent for Po Lo. "That friend of yours," he said, "whom I commissioned to look for a horse, has made a fine mess of it. Why, he cannot even distinguish a beast's color or sex! What on earth can he know about horses?" Po Lo heaved a sigh of satisfaction. "Has he really got as far as that?" he cried. "Ah, then he is worth ten thousand of me put together. There is no comparison between us. What Kao keeps in view is the spiritual mechanism. In making sure of the essential, he forgets the homely details; intent on the inward qualities, he loses sight of the external. He sees what he wants to see, and not what he does not want to see. He looks at the things he ought to look at, and neglects those that need not be looked at. So clever a judge of horses is Kao, that he has it in him to judge something better than horses." When the horse arrived, it turned out indeed to be a superlative animal.
I’ve reproduced the tale here not just because I invariably go out of my way to recommend a good prose pacifier to parents or older brothers of ten-month-old babies but for quite another reason. What directly follows is an account of a wedding day in 1942. It is, in my opinion, a self-contained account, with a beginning and an end, and a mortality, all its own. Yet, because I’m in possession of the fact, I feel I must mention that the bridegroom is now, in 1955, no longer living. He committed suicide in 1948, while he was on vacation in Florida with his wife . . . . Undoubtedly, though, what I’m really getting at is this: since the bridegroom’s retirement from the scene, I haven’t been able to think of anybody whom I’d care to send out to look for horses in his stead.”
