Found on a PC at NASA: A VISIT FROM ST. NICHOLAS FOR READERS IN THEIR 23RD YEAR OF SCHOOLING '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 cerebra. My conjugal partner and I, attired in our nocturnal cranial coverings, were about to take slumbrous advantage of the hibernal darkness when upon the avenaceous exterior portion of the grounds there ascended such a cacophony 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 the fenestration, noting thereupon that the lunar brilliance without, reflected as it was on the surface of a recent crystalline aqueous precipitation, might be said to rival that of the solar meridian itself -- thus permitting my incredulous optical sensor to peruse a miniature airborne runnered conveyance drawn by an octet of diminutive specimens of the genus Rangifer, piloted by a miniscule, aged chauffeur so ebullient and nimble that it became instantly apparent to me that he was indeed our anticipated caller. With his undulate motive power traveling 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 my 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 the 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 molar regions and nasal aptenance 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 hirsuite facial adornment appeared like small, tabular and columnar crystals of frozen water. Clenched firmly between his incisors was a smokingpiece 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. Without utterance and with dispatch, he commenced filling the aforementioned hosiery with 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 affected 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 yuletides to the planetary constituence, and to that self-same assemblage my sincerest wishes for a salubriously beneficial and gratifyingly pleasurable period between sunset and dawn." IS THERE A SANTA CLAUS? As a result of an overwhelming lack of requests, and with research help from that renown scientific journal SPY magazine (January, 1990) - I am pleased to present the annual scientific inquiry into Santa Claus. 1) No known species of reindeer can fly. BUT there are 300,000 species of living organisms yet to be classified, and while most of these are insects and germs, this does not COMPLETELY rule out flying reindeer which only Santa has ever seen. 2) There are 2 billion children (persons under 18) in the world. BUT since Santa doesn't (appear) to handle the Muslim, Hindu, Jewish and Buddhist children, that reduces the workload to to 15% of the total - 378 million according to Population Reference Bureau. At an average (census) rate of 3.5 children per household, that's 91.8 million homes. One presumes there's at least one good child in each. 3) Santa has 31 hours of Christmas to work with, thanks to the different time zones and the rotation of the earth, assuming he travels east to west (which seemes logical). This works out to 822.6 visits per second. This is to say that for each Christian household with good children, Santa has 1/1000th of a second to park, hop out of the sleigh, jump down the chimney, fill the stockings, distribute the remaining presents under the tree, eat whatever snacks have been left, get back up the chimney, get back into the sleigh and move on to the next house. Assuming that each of these 91.8 million stops are evenly distributed around the earth (which, of course, we know to be false but for the purposes of our calculations we will accept), we are now talking about .78 miles per household, a total trip of 75-1/2 million miles, not counting stops to do what most of us must do at least once every 31 hours, plus feeding and etc. This means that Santa's sleigh is moving at 650 miles per second, 3,000 times the speed of sound. For purposes of comparison, the fastest man-> made vehicle on earth, theUlysses space probe, moves at a poky 27.4 miles per second - a conventional reindeer can run, tops, 15 miles per hour. 4) The payload on the sleigh adds another interesting element. Assuming that each child gets nothing more than a medium-sized lego set (2 pounds), the sleigh is carrying 321,300 tons, not counting Santa, who is invariably described as overweight. On land, conventional reindeer can pull no more than 300 pounds. Even granting that "flying reindeer" (see point #1) could pull TEN TIMES the normal anount, we cannot do the job with eight, or even nine. We need 214,200 reindeer. This increases the payload - not even counting the weight of the sleigh - to 353,430 tons. Again, for comparison - this is four times the weight of the Queen Elizabeth. 5) 353,000 tons travelling at 650 miles per second creates enourmous air resistance - this will heat the reindeer up in the same fashion as spacecrafts re-entering the earth's atmosphere. The lead pair of reindeer will absorb 14.3 QUINTILLION joules of energy. Per second. Each. In short, they will burst into flame almost instantaneously, exposing the reindeer behind them, and create deafening sonic booms in their wake. The entire reindeer team will be vaporized within 4.26 thousandths of a second. Santa, meanwhile, will be subjected to centrifugal forces 17,500.06 times greater than gravity. A 250-pound Santa (which seems ludicrously slim) would be pinned to the back of his sleigh by 4,315,015 pounds of force. In conclusion - If Santa ever DID deliver presents on Christmas Eve, he's dead now.
