  íme egy gyönyörû kis fizikai, matematikai számítás szegény Télapóról.
  szegénynek nem lehet könnyű dolga.

  Is there a Santa Claus ? Mathematical study provides NO.
  ----------------------------------------------------------------
  
  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.
  
  
  
  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.
  
  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 percent 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.
  
  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. It means 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 onto
  the next house. Assuming that each of these 91.8 million stops are evently
  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 do at least once every 31 hours, plus feeding,
  etc.
  
  This means that Santa's sleigh is moving at 650 miles per second, 3000
  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.
  
  The payload on the sleigh adds an other 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, a 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 - 353,430 tons. Again, for comparison -
  this is four times the weight of the H.M.S. Queen Elisabeth.
  
  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 athmosphere. 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 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 forces17, 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 Cristmas Eve, HE IS DEAD NOW...
