And where does it go after it leaves the toaster? Here is a simple experiment that will teach you an important electrical lesson: On a cool, dry day, scuff your feet along a carpet, then reach your hand into a friend's mouth and touch one of his dental fillings. Did you notice how your friend twitched violently and cried out in pain? This teaches us that electricity can be a very powerful force, but we must never use it to hurt others unless we need to learn an important electrical lesson. It also teaches us how an electrical circuit works. When you scuffed your feet, you picked up batches of "electrons," which are very small objects that carpet manufacturers weave into carpets so they will attract dirt. The electrons travel through your bloodstream and collect in your finger, where they form a spark that leaps to your friend's filling, then travels down to his feet and back into the carpet, thus completing the circuit. Amazing Electronic Fact: If you scuffed your feet long enough without touching anything, you would build up so many electrons that your finger would explode! But this is nothing to worry about unless you have carpeting. Although we modern persons tend to take our electric lights, radios, mixers, etc. for granted, hundreds of years ago people did not have any of these things, which is just as well because there was no place to plug them in. Then along came the first Electrical Pioneer, Benjamin Franklin, who flew a kite in a lightning storm and received a serious electrical shock. This proved that lightning was powered by the same force as carpets, but it also damaged Franklin's brain so severely that he started speaking only in incomprehensible maxims, such as "A penny saved is a penny earned." Eventually he had to be given a job running the post office. After Franklin came a herd of Electrical Pioneers whose names have become part of our electrical terminology: Myron Volt, Mary Louise Amp, James Watt, Bob Transformer, etc. These pioneers conducted many important electrical experiments -- Among them, Galvani discovered (this is the truth) that when he attached two different kinds of metal to the leg of a frog, an electrical curent developed and the frog's leg kicked, even though it was no longer attached to the frog, which was dead anyway. Galvani's discovery led to enormous advances in the field of amphibian medicine. Today, skilled veterinary surgeons can take a frog that has been seriously injured or killed, implant pieces of metal in its muscles, and watch it hop back into the pond just like a normal frog, except for the fact that it sinks like a stone. But the greatest Electrical Pioneer of them all was Thomas Edison, who was a brilliant inventor despite the fact that he had little formal education and lived in New Jersey. Edison's first major invention in 1877 was the phonograph, which could soon be found in thousands of American homes, where it basically sat until 1923, when the record was invented. But Edison's greatest achievement came in 1879 when he invented the electric company. Edison's design was a brilliant adaptation of the simple electrical circuit: The electric company sends electricity through a wire to a customer, then immediately gets the electricity back through another wire, then (this is the brilliant part) sends it right back to the customer again. This means that an electric company can sell the customer the same batch of electricity thousands of times a day & never get caught, since very few customers take the time to examine their electricity closely. In fact the last year any new electricity was generated in the United States was 1937; the electric companies have been merely re-selling it ever since, which is why they have so much free time to apply for rate increases. Today, thanks to men like Edison and Franklin, and frogs like Galvani's, we receive almost unlimited benefits from electricity. For example, in the past decade scientists developed the laser, an electronic appliance so powerful that it can vaporize a bulldozer 2,000 yards away, yet so precise that doctors can use it to perform delicate operations to the human eyeball, provided they remember to change the power setting from "Vaporize Bulldozer" to "Delicate." ------------------------------ Date: Wed, 12 Dec 84 10:40:02 pst From: Peter Karp Subject: Christmas tidings To: bourne@CMU-CS-A, ces@CMU-CS-J, cohn@SU-SCORE, dw70@CMU-CS-A, karp@SUMEX-AIM, shrager@CMU-CS-A, su-bboards@SU-AIMVAX ReSent-Date: Wed 12 Dec 84 18:31:06-PST ReSent-From: Judy Anderson ReSent-To: info-cobol%mit-ccc@MIT-MC.ARPA A VISIT FROM ST. NICHOLAS ------------------------- Twas the nocturnal segment of the diurnal period preceding the annual yuletide celebration, and throughout our place of residence, kinetic activity was not in evidence among the possessors of this potential, including that species of domestic rodent known as Mus musculus. Hosiery was meticulously suspended from the forward edge of the wood burning caloric apparatus, pursuant to our anticipatory pleasure regarding an imminent visitation from an eccentric philanthropist among whose folkloric appellations is the honorific title of St. Nicholas. The prepubescent siblings, comfortably ensconced in their respective accommodations of repose, were experiencing subconscious visual hallucinations of variegated fruit confections moving rhythmically through their cerebrums. My conjugal partner and I, attired in our nocturnal head coverings, were about to take slumbrous avantage of the hibernal darkness when upon the avenaceous exterior portion of the grounds there ascended such a cacaphony of dissonance that I felt compelled to arise with alacrity from my place of repose for the purpose of ascertaining the precise source thereof. Hastening to the casement, I forthwith opened the barriers sealing this fenestration, noting thereupon that the lunar brilliance without, reflected as it was on the surface of a recent crystalline precipitation, might be said to rival that of the solar meridian itself-- thus permitting my incredulous optical sensory organs to behold a miniature airborne runnered conveyance drawn by eight diminutive specimens of the genus Rangifer, piloted by a minuscule, aged chauffeur so ebullient and nimble that it became instantly apparent to me that he was indeed our anticipated caller. With his ungulate motive power travelling at what may possibly have been more vertiginous velocity than patriotic alar predators, he vociferated loudly, expelled breath musically through contracted labia, and addressed each of the octet by his or her respective cognomen - "Now Dasher, now Dancer..." et al. - guiding them to the uppermost exterior level of our abode, through which structure I could readily distinguish the concatenations of each of the 32 cloven pedal extremities. As I retracted by cranium from its erstwhile location, and was performing a 180-degree pivot, our distinguished visitant achieved - with utmost celerity and via a downward leap - entry by way of the smoke passage. He was clad entirely in animal pelts soiled by the ebon residue from oxidations of carboniferous fuels which had accumulated on the walls thereof. His resemblance to a street vendor I attributed largely to the plethora of assorted playthings which he bore dorsally in a commodious cloth receptacle. His orbs were scintillant with reflected luminosity, while his submaxillary dermal indentations gave every evidence of engaging amiability. The capillaries of his malar regions and nasal appurtenance were engorged with blood which suffused the subcutaneous layers, the former approximating the coloration of Albion's floral emblem, the latter that of the Prunus avium, or sweet cherry. His amusing sub- and supralabials resembled nothing so much as a common loop knot, and their ambient hirsute facial adornment appeared like small, tabular and columnar crystals of frozen water. Clenched firmly between his incisors was a smoking piece whose gray fumes, forming a tenuous ellipse about his occiput, were suggestive of a decorative seasonal circlet of holly. His visage was wider than it was high, and when he waxed audibly mirthful, his corpulent abdominal region undulated in the manner of impectinated fruit syrup in a hemispherical container. He was, in short, neither more nor less than an obese, jocund, multigenarian gnome, the optical perception of whom rendered me visibly frolicsome despite every effort to refrain from so being. By rapidly lowering and then elevating one eyelid and rotating his head slightly to one side, he indicted that trepidation on my part was groundless. Without utterance and with dispatch, he commenced filling the aforementioned appended hosiery with various of the aforementioned articles of merchandise extracted from his aforementioned previously dorsally transported cloth receptacle. Upon completion of this task, he executed an abrupt about-face, placed a single manual digit in lateral juxtaposition to his olfactory organ, inclined his cranium forward in a gesture of leave-taking, and forthwith effected his egress by renegotiating (in reverse) the smoke passage. He then propelled himself in a short vector onto his conveyance, directed a musical expulsion of air through his contracted oral sphincter to the antlered quadrupeds of burden, and proceeded to soar aloft in a movement hitherto observable chiefly among the seed-bearing portions of a common weed. But I overheard his parting exclamation, audible immediately prior to his vehiculation beyond the limits of visibility: "Ecstatic yuletide to the planetary constituency, and to that selfsame assemblage, my sincerest wishes for a salubriously beneficial and gratifyingly pleasurable period between sunset and dawn." -- From Eleonore Johnson at Teknowledge ------------------------------ Date: Thursday, 13 December 1984 11:41 mst From: Rishiyur S.
