And all through the house, 2 creatures were stirring after the kids were in bed. I'll never learn, don't buy thing that need assembly in the cold, dark backyard!

Merry Christmas to all of my extended family tonight

....... It's not quite Christmas day here yet, but for those on the East coast, it's Christmas day. Merry Christmas to all and hope that Santa brings you all that you are hoping for.

The worst things to read or hear on Christmas Eve:

1) some assembly required

2) batteries not included

It's 2220 here in AZ. Merry Christmas to all....

Kids are asleep and presents are wrapped and under the tree. And it's not 2 am! (like last year...).

Cheers to all.

An Engineer's Christmas

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 (except maybe in Japan where he is known as 'Annual Gift Man') 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 household, that comes to 108 million homes, presuming there is at least one good child in each. Santa has about 31 hours of Christmas to work with, thanks to the different time zones and the rotation of the earth, assuming 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 1/1000 th of a second to park the sleigh, hop out, jump down the chimney, fill the stocking, 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 onto 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.

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 thousands tons, not counting Santa himself. On land, a conventional reindeer can pull no more than 300 pounds. Even granting that the "flying" reindeer can pull 10 times he 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). 600,000 tons travelling 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 accelerating from a dead stop to 650 m.p.s. in .001 seconds, would be subjected to acceleration forces of 17,000 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.
Merry Christmas! Dan

Is Christmas morning now. Kids are still asleep. It's nice having older kids. Their sleep becomes more precious than ripping into paper at an ungodly hour.
I did get to experience the fun of watching little one's eyes light up tho. Yesterday my office took christmas too a young girl that works for me. A single mom with three kids whose deadbeat father is nowhere to be seen. We got word that she didn't have a tree or presents for the kids. So, we shut down the office and took a tree and some toys to the kids.
I'm quite the grinch when it comes to christmas season, but seeing those kids enjoy those toys did kinda melt the heart.
I guess what I'm saying is let's remember those that aren't as blessed as we are.
Merry Christmas all.
