Santa, Skepticism, and the Holiday Season

Posted by mattusmaximus on December 19, 2015

A recent article posted by skeptical writer Greta Christina titled No, Virginia, There Is No Santa Claus over at Freethought Blogs caught my eye. In it, she makes a compelling argument for why it is that children should be skeptical of some adults’ attempts to hoodwink them…

… You should be extremely suspicious of anyone who tells you that you’re a bad person for not believing things you have no good reason to think are true. You should be extremely suspicious of anyone who tells you that, in order to experience love and generosity and devotion, you have to believe in Santa Claus, or any other mythical being there’s no good evidence for. You should be extremely suspicious of anyone who tells you that “childlike faith” — i.e., believing things you have no good reason to think are true — is somehow in the same category as poetry and romance. You should be extremely suspicious of anyone who tells you that the world would be dreary without Santa Claus: that without Santa Claus, the light of childhood would be extinguished, we would have no enjoyment except in sense and sight, and existence would be intolerable. That is one seriously messed-up idea.

Adults know that there is no Santa Claus. If they tell you otherwise, they are lying to you. That’s okay: some parents tell their children that Santa Claus is real as a sort of game, and there’s no evidence that this does any real harm. But if anyone keeps lying to you — about Santa Claus, or anything else — when you ask them a direct question and explicitly ask them to tell you the truth? That’s a problem. And if anyone tries to make you feel ashamed, or inferior, or like your life will be dreary and intolerable, simply because you don’t believe in this lie they’re telling you… you should be extremely suspicious. They are trying to manipulate you. It is not okay.

I agree wholeheartedly with Greta’s thoughts on this matter, and I recommend that you read her entire post on the topic. That said, I’d also like to take this opportunity to share (or re-share) some of my previous work on the entire matter of skepticism, education, Santa Claus, and the Holiday Season in general.

1. If Santa ever existed, he didn’t live for long

This is perhaps what I’m most famous (or infamous) for on this topic: I use physics to kill Santa Claus; to be more accurate, I use physics to kill the idea of Santa Claus (because it’s impossible to kill something that doesn’t exist in the first place). Originally, I made a post years ago outlining how, assuming the jolly old elf existed in the first place, Santa would be simultaneously fried to a crisp and squashed into jelly in his attempts to deliver presents on Christmas Eve.

Then, last year, I decided to up my game a bit. I got commissioned to write an article for a UK Education periodical on the topic, and I went so far as to perform the explicit calculations showing that not only would Santa have to absorb the equivalent  energy of 20 Tsar-Bomba nuclear weapons every second due to air drag, but he’d also experience roughly 192 million g’s worth of acceleration in the process – more than enough to make short work of him!

Now, I’d like to share with you the specific PowerPoint I use to annihilate the Santa Claus myth. Feel free to download and use it as you will :)

2. The Santa Myth isn’t all bad and can serve a skeptical purpose

I’ve argued before that I think the myth of Santa Claus can actually be a very useful tool to promote skepticism and critical thinking in young children. Please note that my argument here is not in any way, shape, or form in opposition to Greta Christina’s well reasoned post above; I simply think that it is good for children to work out for themselves that Santa isn’t real, and once they’ve done that they should give the stink-eye to anyone who tries to give them grief or make them feel bad for not believing in the fairy tale. Even better, once kids figure it out, they should go forth and argue with their peers about the existence of Santa; what could be better than skeptical children promoting critical thinking to other kids?

3. It isn’t all about Santa

While it is perhaps true that Santa Claus is the most popular aspect of the Holiday Season, it certainly isn’t the only myth of the Holiday Season. Once children become skeptical of the existence of Santa Claus, then why not encourage them to ask questions and become more critical of other aspects of the season? For example, they can take the following myths and misconceptions quiz on the issue, examining everything from the more pagan aspects of Christmas to blatant falsehoods regarding the Gospels in the Bible. After all, once one starts to question one myth, then why not another?…

The Physics of Santa 2.0

Posted by mattusmaximus on December 20, 2014

Years ago I posted here about how I kill Santa with science, and it goes without saying that doing so can get quite a reaction out of people. Some reactions have been negative, but a surprising number of people have contacted me actually thanking me for killing the Santa myth.  In fact, I was recently commissioned to write a formal article on killing Santa with science for TESConnect, an educational magazine and networking organization centered in the UK.  I am happy to share with you the full article in all of its colored glory, along with explicit physics calculations, below… Happy Holidays!🙂

Myths and Misconceptions About Christmas

Posted by mattusmaximus on December 15, 2012

Once again the season is upon us, when much of the world’s population celebrates Christmas and all the holiday trappings thereof.  I’ve made numerous posts on the subject before, including The Physics of Santa Claus, how the idea of Santa Claus can be used as a tool to teach critical thinking to kids (including a podcast interview I did on the subject), and the tongue-in-cheek celebration of Newtonmass 🙂

And, of course, along with all of that, there is not to be missed the chance to spread some skepticism and critical thinking regarding Christmas in general.  To help with that, my skeptical colleague Phil over at Skeptic Money has once again posted the Ultimate Christmas Quiz that you can use to test your (and that of your friends and family) knowledge of the holiday.  You might be surprised to learn about all of the myths and/or misconceptions which exist in popular culture about Christmas…

Ultimate Christmas Quiz

Bonus Question! (re-gifted from the Ultimate Easter Quiz)

13. Who wrote these gospels, anyway?

a. Matthew, Mark, Luke, John – I mean, come on, it says so right there.

b. Actually, none of the gospels even claim to be written by eyewitnesses -all were originally anonymous and written at least a generation later.

Merry Newtonmass!

Posted by mattusmaximus on December 23, 2011

It’s almost December 25th, and while some people are celebrating certain holidays (Dies Natalis Solis Invicti!), one thing I like to do is take a little time to recognize one of the greatest contributors to modern science: Sir Isaac Newton.  Newton was born on December 25th, 1642 (according to the old-style Julian calendar)…

I totally stole this image from Skeptico🙂

Isaac Newton was an English physicist and mathematician.  The son of a yeoman, he was raised by his grandmother.  He was educated at Cambridge University (1661-1665), where he discovered the work of Rene Descartes.  His experiments passing sunlight through a prism led to the discovery of the heterogeneous, corpuscular nature of white light and laid the foundation of physical optics.  He built the first reflecting telescope in 1668 and became a professor of mathematics at Cambridge in 1669.  He worked out the fundamentals of calculus, though his work went unpublished for more than 30 years.  His most famous publication, The Principia Mathematica (1687), describes his works on the laws of motion (now named for Newton), orbital dynamics, tidal theory, and the theory of universal gravitation, and is regarded as the seminal work of modern science.  He was elected president of the Royal Society of London in 1703 and became the first scientist ever to be knighted in 1705.  During his career he engaged in heated arguments with several of his colleagues, including Robert Hooke (with whom he argued over authorship of the inverse-square relation of gravity) and Gottfried Leibniz (over the authorship of calculus).

Of course, while Newton was certainly no saint (he had a reputation for being kind of a nasty guy, especially to his academic opponents, and he also dabbled in alchemy, Biblical numerology, divination, the occult and many other things we’d consider quite woo-ish today), we can see from his accomplishments listed above just why he is regarded as one of the greatest scientists of all time, and it is for those contributions to humanity that we remember him.

So this December 25th, take some time to raise a glass, and perhaps admire a falling apple, to toast Isaac Newton and his legacy.  Cheers!🙂

‘Tis the Season… For the Ultimate Christmas Quiz!

Posted by mattusmaximus on November 6, 2011

Well, the traditional Holiday season is upon us, which means that many Christian fundamentalist zealots will no doubt spend considerable time and energy annoying the rest of us with all manner of drivel regarding the “truth” of their beliefs.  But it has been my experience that many of these fundamentalists don’t actually understand their own religion…

For Example: The myth of the Nativity is a big one propagated by too many Christians who are horribly ignorant of the origins of their own religion.

So, in the spirit of addressing many of the misconceptions and false claims espoused by these fundamentalists concerning Christmas and Jesus Christ, I would like to share with you the Ulitmate Christmas Quiz (kudos to my skeptical colleague Phil @ Skeptic Money for passing this along)…

“How I Killed Santa”: The Physics of Santa Claus

Posted by mattusmaximus on December 18, 2009

I’m a bad, bad person.  No kidding, I’m bad – really, really bad.  I say this because in my physics classes today, I killed Santa Claus. Well, to be more accurate, what I did was use our knowledge of physics to kill the fantasy of Santa Claus (because it’s pretty damn hard to kill something that isn’t real).  And I have no guilt at all for doing this, because if 16-18 year old kids are still harboring some kind of actual belief in Santa, then they need a strong dose of reality laid on them!🙂

So how did I do it?  Just how did I kill the Santa fantasy?  Here’s how… I used a brief PowerPoint presentation to make the following argument:

  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, and assuming he travels east to west (which seems logical). This works out to 822.6 visits per second.
  4. This is to say that for each Christian household with good children, Santa has 1/1000th of a second to park, hop out of his 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.
  5. 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 purpose of our calculations we will accept), we are now talking about .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 and etc.
  6. 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.
  7. 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.
  8. On land, conventional reindeer can pull no more than 300 pounds. Even granting that “flying reindeer” (refer to point #1) could pull TEN TIMES the normal load, 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 Queen Elizabeth (the ship, not the woman).
  9. 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!
  10. In short, they will burst into flames almost instantaneously, exposing the reindeer behind them, and create a deafening sonic boom in their wake. The entire reindeer team will be vaporized within 4.26 thousandths of a second! Santa, meanwhile, will be subjected to forces 17,500 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!!!

Thus, in conclusion: If Santa ever DID deliver presents on Christmas Eve, HE’S DEAD NOW!!!
