santa claus north pole norad xmas physics stats update 2010

Here's the 2010 link to the Santa tracking system created by NORAD.

An ideal last minute gift this year is, of course, the rashbre novel -The Triangle.

But for those of you who are more interested in the technology of Santa, NORAD's FAQs provide the following:

Plenty of people have calculated Santa's speed to cover the world, famously Joel Potischman and Bruce Handy who did the physics of the speed and payload performance criteria for Santa's sleigh. Like most, I'm respectful of this but am also intrigued by some of the assumptions in the original calculation:

The most notable corrections to be applied are:

- Santa delivers no gifts to naughty children (not even coal)
- Naughty to nice ratio is 1:9
- As confirmed by NORAD, one Santa distributes all of the gifts.
- There is only one family per household.
- Santa bypasses non Santa belief system houses.
- Reindeer have recently eaten fresh magic acorns.

Calculation Assumptions:

- World population = 6 billion
- Children under 18 = 2 billion
- Global Santa based belief systems: 33%
- Max children requiring delivery therefore 667 million
- Children per household: 3.5 (may seem high?)
- Number of households requiring distribution 189 million
- Eastern orthodox using Jan 5 instead of Dec 25 = 16 Million
- Target Households = 173 million on Dec 25
- Target Households after naughty to nice = 156 million
- Estimated child bed time 21:00 (9pm) with 7 hours sleep.

(child sleep duration on Dec 24 may also require revision)

Gives circa 31 hours (24+7) for all deliveries
Time is 1860 mins or 111,600 seconds

Average number of homes to visit per second = circa 1400.
So average delivery per household is 715 microseconds, which is why Santa normally appears a bit blurry (I previously thought it was the sherry)

Land surface minus Antarctica is around 79 million square miles. Distribute destinations evenly = 0.7 miles between households creating a total distance of circa 110 million miles.

So 110 million miles in 31 hours = 3.6 million miles an hour or circa 1000 miles per second or Mach 4770 at a linear speed.

This explains Rudolph's red nose because of air resistance creating around 20 quintillion Joules of energy per second, which would convert a non reindeer nose to charcoal at such energy levels.

Luckily Santa has lots of special powers so these mere physics facts are no problem to such a superhero.

And ps. my list is in the chimney awaiting collection.

mince pies 2010 calorie counts

The pub on Wednesday already had "New Year 2011" streamers and those little poppers strewn around and I asked the barman whether he thought it was a little unusual.

"It is really," he replied, "..and the owners will change it two or three more times before the new year in any case."

This year we have Christmas merchandise jostling next to a surprisingly green-themed Halloween (what happened to orange?) and security cabinets full of explosives ready for November 5th. There's also a few hot crossed buns around so I guess anything goes.

I decided to test reactions by buying some mince pies (99p standard version) but no-one is at all phased and I've been reliably informed that another store is selling star shaped Christmas cakes as fast as they can stock them.

Instead, I'll be preoccupied with the individual payload of a single 'shop' mince pie.

My first selection are an already respectable 245 kcalories and as they are the ''basic edition" I'm sure there will be others with higher counts. A single pack of these would blow out almost a whole day's worth of recommended daily allowances, according to the packaging.

The quest continues. Tip-offs welcome.

xmas party games

Survivors of rashbre central's previous seasonal festivities will know that there's a certain point when the silly hats and party games make an appearance.

Not the Nintendo / X-Box360 / Playstation variety, but games involving old wrapping paper, sticky tape, fruit and the like. For the convenience of others, here's a few sure fire winners, which can be played at everything from amateur through to full Pro standard.

Required items: Wrapping paper, sticky tape, magazines, newspapers, highlighter pen, pins

1) Guess the name : Yes - simply providing the guests with paper hats or pin on labels which they can't see with the name of a sleb (celebrity) on it. They have to guess with the Yes/No answers. Classed as an icebreaker. Marilyn Monroe, George Bush, Frankenstein, Albert Einstein, Babe Ruth, Jason Bourne, 007, Mickey Mouse, Madonna, Britney Spears, Beyonce. You get the idea.
2) Dress the person : Kinetic Game, two teams: 2-5 minutes. Select someone to be dressed using either old wrapping paper or a couple of recent magazines or newspapers.
3) Kipper racing : multiple teams. needs a long clear indoor space. cut or tear a largish fish shape from a sheet of wrapping paper or anything similar to hand. Add detail such as a hole for the eye, maybe a dorsal fin. Lie them flat on the floor and give other team members further sheets of paper/magazines to use to create air currents to propel the fish from a start line to a distant improvised finishing line.
4) Tell a tale : Pre select some groups of 7 unusual words from a magazine or newspaper article. Hand them to each team and and ask each team member in turn to tell a story using the seven words. Other teams have to try to guess the words.
(Example words from random article today : luckier; heterosexual; chevrolet; banana; promoted; quitter; eggs. and from another page: emissions; cruise; leisurely; overcome; scoop; howling; endurance...you get the idea.)
5) Pass the orange : Why wait until after the dinner has finished to play this game? goes great with coffee.
6) Pictionary: drawing fast pictures based upon words. The boxed set is best for this one.
7) GrEEn GlaSS dOOr : The person in charge suggests playing this and that everyone else can try to be selected to go through the green glass door by suggesting appropriate pairs of things. Things that get in are a pOOl but no water; glaSS but no picture; MiRRor but no reflection (ie the first thing needs a double letter in it.. Play till last person gets it)
8) GGD variants : Play GGD (7) where instead of double letters, each sentence said by the next person has to start with a vowel "...and blah blah bla; ...or blah blah blah ...obviously" and another variant vowel/then consonant and another variant is start with next letter of alphabet.
9) Alphabet Game : Choose topic (Animals, Cars, Candy Bars, Popstars, Drinks). Start at A and round robin through to Z.
10) Stirring the Mush : Announce you are stirring the mush and (eg stand up, sit down, scratch your ear etc). Then start stirring the mush by any hand/body gesture you like. The invite someone to copy. the trick is thay have to do what you did BEFORE you started stirring the mush (eg scratch ear etc). Tell them whether they have passed or not then select next 'victim'. Repeat until all have worked it out.
11) Erect-a-pup : More newspaper for this two in -oner. Part one. Teams. who can make the longest tube in 2 minutes from rolled up paper? Sounds easy. Just watch what happens. Part Two. Now, in another three minutes make a model life sized puppy out of tubes of newspaper. Warning that some puppies will have 3, 5 legs at the end of this.

I think thats enough to get started. No animals harmed in the testing of these entertainments. You'll have to email me for the (ahem) rules of the frying pan and wooden spoon game...and don't forget charades!

santa sighting

My first 2008 Santa sighting today, outside rashbre central.

I'm guessing it was the naughty/nice reconnaissance run but it was hardly low profile - all the navigation lights were on.

I only managed to get one photo above because of the extreme speed.

I know its still early, but I suppose the countdown has begun and NORAD tracking is back online - more modestly, around our way there's a Christmas Fair on Friday.
