That is officially the least funny thing I have read on the internet.

The Klaus Barbie story is funnier.

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.

This is gayer than Marcus Bachmann listening to Nickleback.

Have a hunch that, given the attitude of Americans, Santa is in line to be shot down and face rendition.

Death_Poot: 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).

You forgot the time it takes him to boink the missus of the house underneath the christmas tree. Talk about wham-bam-thank-you-ma'am.

"Mr. Claus has flagrantly violated children's privacy, collecting their consumer preferences for toys and also tracking their behavior so as to judge and maintain a data base of naughtiness and niceness,"

Sorry douche, but Santa gets his data when children voluntarily send in their consumer preferences and the parent gives consent to observe the child's niceness to naughtiness ratio.

Don't Troll Me Bro!: Don't Troll Me Bro!: Death_Poot: 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.

Centrifugal forces are not real. Centripetal acceleration is caused by a normal force being applied to tangential motion. This causes the tangential velocity vector to change as a function of time. In most applications where people experience "centrifugal force" it is the result of a system where a normal force is applied such that you are in a constant state of acceleration towards a central point.

But other than that I enjoyed it. :)

Obligatory:

Death_Poot: 600,000 tons traveling at 650 miles per second creates enormous air resistance

Wouldn't that depend more on the profile than the mass? If we we were talking about a really dense BB vs a huge sack of feather, the air resistance wouldn't be anywhere near the same.
