Question
Santa Claus: An Engineers 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 creates 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 accellerating 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.
Therefore, if Santa did exist, he's dead now.
Answer
oh, yeah. Engineers really ruin everything for kids
Answer
then... santa's... not.. real....?!?!??
LMFAO. it just ruined my dreams. i was really good this year!! ahaha but i like the scientific view of santa.
Answer
ilike this one too
god i loved those expression when the kids find out santa is fake after believing that he was real for years.
Answer
Ahahaha. I'm gonna be an engineer. x]
Answer
I remember reading this. I like the scientific view on Santa Claus. lol
Answer
LOL! XD nice explanation, I can't believe I read it all.
Answer
hahaha that is genius. engineering, here I come!
Answer
Haha... that should put the children's mind straight... the truth being revealed... a funny scientific view of Santa...
Answer
thanks for ruining my belief....I'm looking 4ward to Santa's presents
i've been good this year
Anyway, i must say it's a good joke
Wonder who has the exact figures
Answer
Wow, nice calculations XD!
Answer
engineers always ruin everything. (IMG:style_emoticons/default/tongue.gif)
but i like this scientific view. lol.
Answer
LOL wow. i saw in a movie when i was little where the santa stops time, turns into magic sprinkles and teleports into the house..
Answer
aha. i've heard this one from my physics teacher (IMG:style_emoticons/default/tongue.gif)
Answer
What? I can't believe santa's not real or he's dead....
I've been living a lie for 21 years!
Answer
that was kinda cool -- science kills so much things. i love it!
Answer
LOL, now the question is. would you rather believe that santa is real and dead or not real at all?
Answer
hahh that was cute. poor santa.
Answer
This is completely false because Santa uses magic.
Answer
puhaha i just noticed that i never knew santa until like the 2nd grade. lol so i knew he was fake. and i remember when the kids would lie that they saw santa.
