SANTA CLAUS: An Engineer's Perspective


I. There are approximately two billion children (persons under 18) in the world. However, since Santa does not visit children of Muslim, Hindu, Jewish or Buddhist religions, this reduces the workload for Christmas night to 15% of the total, or 378 million (according to the Population Reference Bureau). At an average (census) rate of 3.5 children per house hold, that comes to 108 million homes, presuming that there is at least one good child in each.



II. Santa has about 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 seems logical). This works out to 967.7 visits per second. This is to say that for each Christian household with a good child, Santa has around 1/1000th of a second to park the sleigh, hop out, jump down the chimney, fill the stockings, distribute the remaining presents under the tree, eat whatever snacks have been left for him, get back up the chimney, jump into the sleigh and get on to the next house. Assuming that each of these 108 million stops is evenly distributed around the earth (which, of course, we know to be false, but will accept for the purposes of our calculations), we are now talking about 0.78 miles per household; a total trip of 75.5 million miles, not counting bathroom stops or breaks. This means 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, the Ulysses space probe, moves at a poky 27.4 miles per second, and a conventional reindeer can run (at best) 15 miles per hour.



III. The payload of the sleigh adds another interesting element. Assuming that each child gets nothing more than a medium sized Lego set (two pounds), the sleigh is carrying over 500 thousand tons, not counting Santa himself. On land, a conventional reindeer can pull no more than 300 pounds. Even granting that the "flying" reindeer could pull ten times the normal amount, the job can't be done with eight or even nine of them --- Santa would need 360,000 of them. This increases the payload, not counting the weight of the sleigh, another 54,000 tons, or roughly seven times the weight of the Queen Elizabeth (the ship, not the monarch).



IV. 600,000 tons traveling at 650 miles per second crates enormous air resistance --- this would heat up the reindeer in the same fashion as a spacecraft re-entering the earth's atmosphere. The lead pair of reindeer would absorb 14.3 quintillion joules of energy per second each. In short, they would burst into flames almost instantaneously, exposing the reindeer behind them and creating deafening sonic booms in their wake. The entire reindeer team would be vaporized within 4.26 thousandths of a second, or right about the time Santa reached the fifth house on his trip.



Not that it matters, however, since Santa, as a result of accelerating from a dead stop to 650 m.p.s. in .001 seconds, would be subjected to centrifugal forces of 17,500 g's. A 250 pound Santa (which seems ludicrously slim) would be pinned to the back of the sleigh by 4,315,015 pounds of force, instantly crushing his bones and organs and reducing him to a quivering blob of pink goo.



V. Therefore, if Santa did exist, he's dead now.

And your point is??? You're just jealous cuz a child does not have to know all the engineering and mathematical forumulas, and can just trust in his own vision of what Santa is, and how he gets around. Oh, by the way, was this any of the same engineering logic that said it was impossible to do a quarter mile in less than 5 seconds??? Next I suppose you will tell me that the Easter Bunny is a crock too !!!! Merry Christmas, all. Santa exists, engineers are make-beleive !!!!!!!!

Ho, ho, ho. I'm far from dead.............at least I think so!

Dead tired maybe, but not dead. Today me and the reindeer are kickin' back. It was quite a night!! Hope all you boys are happy with your gifts. You engineer types who subscribe to the above theory may want to plan ahead and get a coal fired furnace for next year though!

Oh, Mrs. Claus is about to get the ham and turkey out on the table, I better get goin'. If I don't get to it before the elves, there won't be enough left......................and after last night I'm REALLY hungry!!

Merry Christmas!!!!

Another great year, Santa. I still beleive in all sorts of miracles!!!

Hey santa, i got ripped! A slinky? Wheres my mondello intake? Comeon, I help people on the side of the road, clocked in voluntary community service, and fix relitives cars for free! A slinky? what did I do wrong?

Santa is a little busy right now...
