NEKAJ DEJSTEV O BOŽIČKU
1. Nobena znana pasma jelenov ne zna leteti
. Na srečo pa obstaja še vsaj 300 000 vrst organizmov, ki jih je treba še klasificirati in čeprav večina od njih odpade na insekte in mikrobe, možnost za leteče jelene še vedno obstaja.
2. Na svetu je kakšni 2 milijardi otrok (pod 18 let). Vendar, ker se Božiček (kot vsaj kaže) ne ukvarja z muslimani, hindujci, judi in budisti, se ta številka skrči na 15% osnove, torej na bednih 378 milijonov. Svetovno povprečje je 3,5 otroka na družino, teh pa je torej 91,8 milijonov. Predpostavljamo, da ima vsaka družina vsaj enega pridnega otroka.
3. Božiček ima 31 ur časa, da razdeli darila.
To pa zato, ker ima opravka z različnimi časovnimi conami in rotacijo Zemlje, če seveda obvlada logiko in potuje od vzhoda na zahod. Opraviti pa mora 822,6 obiskov na sekundo (ob prejšnji predpostavki o enem pridnem otroku na družino). Z drugimi besedami, na voljo ima 0,001 sekunde časa, da parkira sanke, skoči dol po dimniku, napolni štumfe, zmeče darila pod novoletno jelko, spravi vase kaj hrane, ki leži naokoli, spleza nazaj po dimniku, skoči na sani in se odpelje do naslednje hiše
. Če upamo, da je vseh 91,8 milijonov postankov enakomerno razporejenih po Zemlji (in zaradi lažjega računanja bomo to kar privzeli), potem je razdalja med dvema hišama 1,26 km, celotno potovanje pa je dolgo 121,5 milijonov km. In v to sploh ni vračunana pot in čas, ki gre za to, kar mora vsak človek storiti vsaj enkrat na 31 ur (tja kamor gre še Božiček peš ). Skratka, Božičkove sanke drvijo s 1050 km/s, 3600-krat hitreje od zvoka. Za primerjavo- najhitrejše vozilo, sonda Ulysses, se premakne samo za 40 km vsako sekundo. Vrhunsko trenirani jelen pa lahko teče največ 24 km/h, pa še to ne prav dolgo.
4. Teža sank je še ena zanimiva zadeva. Če vsak froc
dobi srednje veliko škatlo LEGO kock (0,9 kg), potem sanke tovorijo 340 200 ton, brez Božička, ki pa ga vsi brez izjeme opisujejo kot obilnega. Običajen jelen na tleh vleče največ 136 kg. Tudi če leteči jeleni vlečejo desetkrat več, jih potrebujemo več kot 7 ali 8. Namreč kar 250.100, kar pa poveča težo sank na 372 330 ton. Luksuzna čezoceanska ladja Queen Elizabeth tehta komaj četrtino tega.
5. 372 330 ton pri 1050 km/s ustvari opazen zračni upor. Jelenčki se segrejejo tako kot shuttle
, ki prihaja v atmosfero. Vodilni par jelenov tako absorbira 14,3 trilijonov (10 na 18) joulov. Na sekundo. Vsako. Skratka, zelo kmalu bosta oba jelenčka zagorela in izpostavila zračnemu uporu naslednji par, ki pri tem prebije zvočni zid. Celotna ekipa jelenov bo izparela v 0,00426 sekunde. Medtem bo Božiček izpostavljen centrifugalnemu pospešku, 17 500-krat večjemu od gravitacijskega. 110 kg težak Božiček (morda je shujšal) je tako prikovan na sani, kot da bi tehtal 1925 ton (dokler ne bo po 0,00426 sekunde prišel na vrsto za izparevanje). Če je torej Božiček kadarkoli razdeljeval darila, potem je zdaj mrtev. Vendar, vse do sedaj smo računali na to, da obstaja samo en Božiček. Izračunave mu dajejo boljše možnosti za preživetje, če upoštevamo, da jih je več . Namreč, 1000 Božičkov (1 kilobožiček) ali pa kar milijon Božičkov (1 megabožiček) bi s timskim delom naredilo vse obiske v istem času z manj napredno tehnologijo (in ob manj izparelih jelenih).
Kdo pa opravlja zračni nadzor za megabožička?
Milijon sani in 12 milijonov jelenov zavzame opazen kos neba. Če upoštevamo, da vsaka posadka ni višja od 1,5 m, potem megabožiček zaseda 1500 km vertikalnega zračnega prostora. Mimogrede, zračni koridorji za potniške linije morajo imeti vsaj 200 m medsebojne višinske razlike. Seveda pa kar pogosti pristanki niso všteti.Tudi zračni prostor v višini dimnikov mora biti zelo prometen, še zlasti, ker hiše težijo k temu, da so nagnetene blizu skupaj. Torej- čeprav se megabožiček izogne izparevanju jelenov, mora najbrž imeti velike izgube v zračnih trčenjih. Ampak jaz verjamem v njega/njih. zato pa V+S.

IN ENGLISH
Is there a Santa Claus? - a physicist view
Consider the following:
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 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 .78 miles per household, a total trip of 75-1/2 million miles, not counting stops to do what most of us must do at least once every 31 hours, plus feeding and 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 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, 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 spacecraft 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.> In conclusion - If Santa ever DID deliver presents on Christmas Eve, he's dead now. But i belive in him/them. So V+S

About the game:
USA as a world power? In E-Sim it is possible!
In E-Sim we have a huge, living world, which is a mirror copy of the Earth. Well, maybe not completely mirrored, because the balance of power in this virtual world looks a bit different than in real life. In E-Sim, USA does not have to be a world superpower, It can be efficiently managed as a much smaller country that has entrepreneurial citizens that support it's foundation. Everything depends on the players themselves and how they decide to shape the political map of the game.
Work for the good of your country and see it rise to an empire.
Activities in this game are divided into several modules. First is the economy as a citizen in a country of your choice you must work to earn money, which you will get to spend for example, on food or purchase of weapons which are critical for your progress as a fighter. You will work in either private companies which are owned by players or government companies which are owned by the state. After progressing in the game you will finally get the opportunity to set up your own business and hire other players. If it prospers, we can even change it into a joint-stock company and enter the stock market and get even more money in this way.
In E-Sim, international wars are nothing out of the ordinary.
Become an influential politician.
The second module is a politics. Just like in real life politics in E-Sim are an extremely powerful tool that can be used for your own purposes. From time to time there are elections in the game in which you will not only vote, but also have the ability to run for the head of the party you're in. You can also apply for congress, where once elected you will be given the right to vote on laws proposed by your fellow congress members or your president and propose laws yourself. Voting on laws is important for your country as it can shape the lives of those around you. You can also try to become the head of a given party, and even take part in presidential elections and decide on the shape of the foreign policy of a given state (for example, who to declare war on). Career in politics is obviously not easy and in order to succeed in it, you have to have a good plan and compete for the votes of voters.
You can go bankrupt or become a rich man while playing the stock market.
The international war.
The last and probably the most important module is military. In E-Sim, countries are constantly fighting each other for control over territories which in return grant them access to more valuable raw materials. For this purpose, they form alliances, they fight international wars, but they also have to deal with, for example, uprisings in conquered countries or civil wars, which may explode on their territory. You can also take part in these clashes, although you are also given the opportunity to lead a life as a pacifist who focuses on other activities in the game (for example, running a successful newspaper or selling products).
At the auction you can sell or buy your dream inventory.
E-Sim is a unique browser game. It's creators ensured realistic representation of the mechanisms present in the real world and gave all power to the players who shape the image of the virtual Earth according to their own. So come and join them and help your country achieve its full potential.
Invest, produce and sell - be an entrepreneur in E-Sim.
Take part in numerous events for the E-Sim community.
