The science of 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 15% of the total -- 378 million
according to the 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 seems 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 0.78 miles per household, a total trip of 75.5 million miles,
not counting stops to do what most of us must do at least once every 31
hours, plus feeding, 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, the Ulysses 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 that 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 amount, 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 traveling at 650 miles per second creates enormous 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.
Merry Christmas!
