The water turned to blood

One of the things that bugs me the most about attributing supernatural causes to natural events is that it is, fundamentally, a lazy stance.

Something odd happens, something for which there is no ready explanation.  It amazes me how quickly people jump to "it's a miracle of god" or "an angel did it" if it was good, and "it was Satan" or "a demon did it" if it was bad.  Conspiracy-based explanations are the same; how much simpler it is to say, "a secret evil government cadre is responsible" than it is to look carefully into the phenomenon and really find out what's going on.

I bring this up because of a pond in Wichita, Kansas, which just a couple of days ago turned blood-red.


The owner of the pond, Freddy Fernandez, is pretty sure there's a rational explanation, and when he posted the photos on Facebook, he was adamant that he didn't think it was anything but some peculiar but completely natural phenomenon.  "I just don't want people showing up, thinking this is some Biblical phenomenon or something like that," Fernandez said.

Well, a lot of people beg to differ.

Within hours the photos had been shared thousands of times, and the explanations -- if I can dignify them with that term -- began to fly.  Now, remember; none of these people had actually seen the pond personally, or done any tests of the water.  All they'd seen were a couple of photographs.  But still, here are a few of the thousands of suggestions Fernandez received:
  • The water was poisoned by the government as part of a FEMA-based plan to kill everyone in the Midwest.
  • The pond water was contaminated by chemicals rained out from "chemtrails."
  • The blood-red color is a new life form, a highly pathogenic bacteria that was seeded there by bioterrorists.
  • Because it's "water turned to blood," this is a sign of the ascendancy of the Evil One, and we should all be on the lookout for the Antichrist.
It was the last one that seemed to be the most popular.  Amongst the missives Fernandez received was one from a gentleman named Edward Cantu that read, "These things happen at the time of the End when Jesus Returns.  Prepare for the coming of the Lord Jesus by repenting of all sin and recieving [sic] Jesus as Lord and Savior.  Ask Him to fill you with His Holy Spirit. God Bless you."

Of course, the more likely explanation is that we're looking at some sort of algal bloom, similar to what happens during a marine "red tide."   But remember:  I haven't been there, either.  I also have run no tests, sampled no water.  The difference is that I used the words "more likely."  I don't know what the blood-red water is, and I'm perfectly content to wait until scientists run some tests (presuming any do) before I settle on an explanation I believe.

That's the thing about being a skeptic; you don't have to have answers immediately.  Or, perhaps, ever.  If there's something you can't explain, you say, "I can't explain that."  Then you look for a rational explanation, using the known facts, and whatever scientific techniques are at your disposal.  You don't immediately jump to saying "it must be the government" or "it must be chemtrails" or "it must be the Antichrist." 

It all reminds me of a former student who couldn't stand not understanding things, not even for a moment.  Her anxiety levels when confronted with having to suspend patiently a state of ignorance were off the charts.  (As you might imagine, science was problematic for her, as in learning science you so often have to keep slogging your way forward, hoping the water will clear eventually.)  One day, I was showing my class how to do a rather difficult numerical analysis technique, and I had a set of data we were going to be working with.  So I put the data on the board, and said, "Copy the data, and after everyone's done I'll tell you what to do next."

So my anxious student copies furiously, finishes first, and then starts to babble.  "What do we do now?  Do you want us to graph it?  Will we need a calculator?  Should I get out graph paper?  What do you want me to do with the numbers?"

And one of her classmates turned to her and said, "Kate, just let the damn data sit there and relax for a moment, okay?"

To which I say: amen.  Just let the damn pond be.  Someone in Wichita who has a background in experimental science will undoubtedly figure out what is going on, and then we'll have an answer.  Until then, it's perfectly okay for the skeptics to wait.  Settling on an answer, based on essentially no hard evidence, is the lazy way out.

Science vs. indoctrination

Indoctrinate (v.) -- to teach someone to accept fully the ideas, opinions, and beliefs of a particular group, in an uncritical fashion; to imbue with a usually partisan or sectarian opinion, point of view, or principle.

Objective (adj.) -- based on facts rather than on feelings or opinions.

There.  I thought I'd get a couple of definitions out of the way right at the outset.  It's not that I think my readers are in any particular need of refreshing their memories on the meanings; it's more that I want to be completely clear about how asinine Missouri State Representative Rick Brattin is being.

My reason for saying this is that, yet again, we are seeing an attack on the teaching of evolution in science classrooms, this time by a lawmaker who not only has no apparent understanding of science, but could use a refresher on how to use the Concise Oxford.  He has introduced a bill into the Missouri House of Representatives that would mandate that schools notify parents if evolution is being taught in biology classrooms -- and allow parents to take their children out of those classes while the topic is being covered, with no grade penalty or loss of credit.

"Our schools basically mandate that we teach one side," Brattin said, in an interview with Kansas City's KCTV News.  "It is an indoctrination because it is not an objective approach.  It’s an absolute infringement on people’s beliefs.  What’s being taught is just as much faith and, you know, just as much pulled out of the air as, say, any religion."

Okay, let me get this straight, Rep. Brattin.  We have, on the one hand, teachers using a curriculum that is based on the work of countless scientists, is supported by every scrap of hard evidence that there is, and has the support of damn near 100% of working biologists.  On the other hand, we have the creation myth of a bunch of illiterate Bronze-Age sheepherders, who also thought that bats were birds (Leviticus 11:19) and that god created day and night before he created the sun (Genesis 1:5-14), and teaches a worldview that is only still around because it's hammered into children's heads incessantly along with the message that questioning the logic of the whole thing is equivalent to listening to Satan.

And the biologists are the ones who are guilty of indoctrination, and of not being objective?


Predictably, scientists are outraged at Brattin's bill.  Glenn Branch, of the National Center for Science Education, said, "The bill would eviscerate the teaching of biology in Missouri.  Evolution inextricably pervades the biological sciences; it therefore pervades, or at any rate ought to pervade, biology education at the K–12 level.  There simply is no alternative to learning about it; there is no substitute activity."

No.  No, there isn't.  Evolution is the founding principle of biology, the idea by which (along with genetics) all of the rest of the science is understood.  Just as chemistry is not comprehensible without atomic theory, and physics is not comprehensible without the concept of forces and energy, biology becomes a meaningless jumble of vocabulary and terminology without the unifying model of evolution through natural selection.  Allowing students to "opt out" of learning about evolution is denying them the opportunity to find out how science actually works -- in essence, allowing them to remain ignorant.  That Brattin thinks the evolutionary model is "faith" and "pulled out of the air" shows that he has no real understanding of the science of biology.

Nor, apparently, does he have all that solid a grasp of the English language.  Religion relies on indoctrination, and a faith-based, subjective approach; science is the opposite.  Scientific principles stand or fall solely on the evidence supporting them.  Calling science indoctrination is as ridiculous as... as...

... as thinking that the sky was solid and made of glass (Job 37:18).

The music of the spheres

It probably sounds uncharitable of me, but I wish that all of the people who can't be bothered to exert the time and effort to learn a little bit of science would stop pretending that they know what they're talking about.

We saw it last week with Ken Ham, blathering on for two hours about "historical science" while Bill Nye stood there staring at him with a "what the fuck are you talking about, dude?" expression that has got to become the basis of a meme somehow.


Of course, it's not just the creationists who babble about scientific concepts like the Second Law of Thermodynamics as if they actually understood them.  The New Age types do the same thing, usually venturing off instead into such esoteric fields as quantum mechanics, evidently mistaking "I don't understand quantum physics" as being the same as "quantum physics means whatever I decide it means."

I ran into an especially good example of this a couple of days ago, over at the loony website Spirit Science and Metaphysics.  And one of their posts, "Here's Why You Should Convert Your Music to 432 Hz," should probably be up for some kind of woo-woo wingnut award.

If there is such a thing.  Which there should be.

In this article, we find out that we are jeopardizing our health, all because we've been tuning our musical instruments wrong:
Most music worldwide has been tuned to A=440 Hz since the International Standards Organization (ISO) promoted it in 1953. However, studies regarding the vibratory nature of the universe indicate that this pitch is disharmonious with the natural resonance of nature and may generate negative effects on human behaviour and consciousness. Certain theories even suggest that the nazi [sic] regime has been in favor of adopting this pitch as standard after conducting scientific researches to determine which range of frequencies best induce fear and aggression. Whether or not the conspiracy is factual, interesting studies and observations have pointed towards the benefits of tuning music to A=432 Hz instead.

432 Hz is said to be mathematically consistent with the patterns of the universe. Studies reveal that 432 hz tuning vibrates with the universe’s golden mean PHI and unifies the properties of light, time, space, matter, gravity and magnetism with biology, the DNA code and consciousness. When our atoms and DNA start to resonate in harmony with the spiraling pattern of nature, our sense of connection to nature is said to be magnified. The number 432 is also reflected in ratios of the Sun, Earth, and the moon as well as the precession of the equinoxes, the Great Pyramid of Egypt, Stonehenge, the Sri Yantra among many other sacred sites.
Count 'em up, folks.  We have:
  • vibrational frequency
  • resonance
  • Nazis
  • the "Golden Mean"
  • the pyramids
  • conspiracies
  • a "grand unified theory"
  • DNA
  • spirals
  • Stonehenge
  • some vague shit about astronomy
  • "sacred sites"
  • light, time, space, matter, gravity, and magnetism
That's it, folks.  I think we can pack it in; we have reached Bullshit Nirvana, here.

Oh, yeah, and it wouldn't be complete without a quote from Nikola Tesla:
“If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.” – Nikola Tesla
Presupposing, of course, that you have taken a physics course and understand what anything that Nikola Tesla said actually means.

We're then shown a bunch of photographs that are supposed to be relevant, including ones that look like this:

[image courtesy of the Wikimedia Commons]

These images are the patterns that emerge from standing waves in a metal plate (either free or forced vibrations); there's nothing mysterious about them.  (Although the theory behind the patterns is wildly complex.  I have a bachelor's degree in physics, and the math is way beyond anything I am capable of comprehending.)  Once you know what the images are, it's hardly a surprise that using a different frequency (432 Hertz rather than 440) will produce a different pattern.  But what they're telling us boils down to the 432 Hertz pattern somehow being "prettier..." which translates, apparently, to its having beneficial health effects.

Or something.  It's kind of hard to tell, frankly, what they do mean.  If you thought the preceding quoted paragraphs were bad, take a gander at this one:
All of the frequencies in the spectrum are related in octaves, from gamma rays to subharmonics. These colors and notes are also related to our Chakras and other important energy centers. If we are to understand that (…) Chakras are connected to the Seven Rays of the Solar Spectrum, then the notes and frequencies we use for the same should be the same. A432 Hz is the tuning of the Cosmic Keyboard or Cosmic Pitchfork, as opposed to the A440 Hz modern ‘standard.’ It places C# at 136.10 Hz ‘Om,’ which is the main note of the Sitar in classical Indian music and the pitch of the chants of the Tibetan monks, who tell us ‘It comes from nature.’
Oh.  The "Cosmic Pitchfork."  That makes total sense.  And I'm sure that the Tibetan monks are perfectly nice people, but the fact is, I wouldn't go to them for instruction on physics, any more than I'd go to Stephen Hawking to receive the teachings of the Buddha.  And talking about "octaves of gamma rays" makes about as much sense as talking about "photons of musical pitch."

But that doesn't matter.  You must immediately retune your guitar and fiddle and other musical instruments, because otherwise your pitch will clash with the Cosmic Keyboard.  And heaven knows we wouldn't want that to happen.

What bothers me about all of this is not that some woo-woo has a weird idea; having weird ideas is kind of the woo-woo raison d'ĂȘtre, after all.  What bothers me is that because the writer of this article is able to throw around some fancy-sounding scientific jargon, coupled with jargon from New Age metaphysics, there is this veneer of sensibility to it -- if you don't know a lot of science yourself, you might be fooled into thinking that what is on this webpage actually says something.  And a lot of people apparently have been fooled.  All you have to do is do a Google search for "432 Hertz tuning" and you will find, literally, hundreds of sites like this one that claim that if you don't retune your music, you are risking remaining unenlightened forever.

I have known more than one person who has regularly been suckered by this kind of stuff.  One of them, a long-ago acquaintance in Seattle who seemed to fall for every piece of freshly-minted New Age nonsense that came down the pike, would have panicked upon reading this, and not only would have immediately paid to have her piano retuned, but she would have done whatever she could to make sure that her CD player was outputting sounds tuned to a scale based on A = 432 Hertz, not the standard 440.  (And she would have attributed every joint pain, headache, and queasy stomach she'd had in the past three years to listening to music at the wrong pitch.)

So just to be clear; there is no health (or emotional, or spiritual) benefit from tuning to 432 Hertz.  It's even been the subject of an experiment, by Trevor Cox, professor of acoustical engineering at the University of Salford, a study that (surprise!) blew down the claim completely.  Put simply, this contention is 100% pure, grade-A, unadulterated pseudoscientific garbage.

And I think to round things out, I'm going to listen to one of my all-time favorite pieces of music -- Domenico Scarlatti's sparkling Sonata in D Major, K. 96, "La Chasse" -- as played by the brilliant Stephen Malinowski (and accompanied by a cool graphic of the musical score).



On a harpsichord tuned to A = 440 Hertz.  Take that, woo-woos.  And tell me if, after listening to this, you felt "aggressive and disharmonious."  Because if so, I think there's something more wrong with you than the way your music is tuned.

The legend of 50 Berkeley Square

Sometimes, with folk tales, you can pinpoint exactly when a legend entered the public awareness.  Someone writes and publishes a story in one of those "True Weird Tales" books or magazines; a report of a haunting makes the local news or newspaper; or, more recently, someone makes a claim in a blog, on Twitter, or on Facebook.

Such, for example, is the famous story of the tumbling coffins of Barbados, about which there seems to be zero hard documentary evidence -- but which first appeared (as a true tale) in James Alexander's Transatlantic Sketches, and which has been a standard in the ghost story repertoire ever since.  Likewise, the story of Lord Dufferin and the doomed elevator operator has a very certain provenance -- Lord Dufferin himself, who enjoyed nothing more than terrifying the absolute shit out of his house guests by telling the story over glasses of cognac late at night.

One of the scariest ghost stories, though, seems to have been built by accretion, and has no certain date of origin.  It's the tale of the "most haunted house in London" -- Number 50 Berkeley Square.

[image courtesy of photographer Sophie Ryder and the Wikimedia Commons]

The house itself is a four-story structure, built in the late 18th century, that looks innocent enough from the outside.  Until 1827 it was the home of British Prime Minister George Canning, which certainly gives it some historical gravitas right from the outset.  But gradually the ownership descended down the socioeconomic scale, and in the late 1800s it had fallen into disrepair.

At some point during that interval, it got the reputation for being haunted.  Apparently, it's the upper floor that is said to be the worst; some say it's occupied by the spirit of a young woman who committed suicide by throwing herself from one of the upper windows, others that it's haunted by the ghost of a young man whose family had locked him in the attic by himself, feeding him through a slot in the door until he went mad and finally died.  Whatever the truth of the non-paranormal aspects -- the suicide of the young woman, or the madness and death of the unfortunate young man -- it's clear that neighbors viewed the house askance during the last two decades of the 19th century.  And that's when the legends really took off.

The earliest definite account of haunting comes from George, Baron Lyttleton, who spent the night in the attic in 1872 after being dared to do so by a friend.  He saw (he said) an apparition, that appeared to him as a brown mist, and that terrified him -- he shot at it, to no apparent effect, and the next morning found the shotgun shell but no other trace of what he'd fired at.  Lyttleton himself committed suicide four years later by throwing himself down the stairs of his London home -- some say, because he never recovered from the fright he'd received that night.

In 1879, Mayfair ran a story about the place, recounting the then-deceased Baron Lyttleton's encounter, and also describing the experience of a maid who'd been sent up to the attic to clean it, and had gone mad.  She died shortly afterward in an asylum, prompting another skeptic, one Sir Robert Warboys -- a "notorious rake, libertine, and scoffer" -- to spend the night, saying that he could handle anything that cared to show up.  The owner of the house elected to stay downstairs, but they rigged up a bell so that Warboys could summon help if anything happened.  Around midnight, the owner was awakened by the bell ringing furiously, followed by the sound of a pistol shot.  According to one account:
The landlord raced upstairs and found Sir Robert sitting on the floor in the corner of the room with a smoking pistol in his hand. The young man had evidently died from traumatic shock, for his eyes were bulged, and his lips were curled from his clenched teeth. The landlord followed the line of sight from the dead man's terrible gaze and traced it to a single bullet hole in the opposite wall. He quickly deduced that Warboys had fired at the 'Thing', to no avail.
The house was (according to the legend) left unoccupied thereafter, because no one could be found who was willing to rent it.  This is why it was empty when two sailors on shore leave from Portsmouth Harbor, Edward Blunden and Robert Martin, decided to stay there one foggy night when they could find no rooms to rent.  They were awakened in the wee hours by a misty "something" which tried to strangle Martin -- beside himself with fright, he fled, thinking his buddy was right behind him.  He wasn't.  When he went back into the house the following morning, accompanied by police, he found the unfortunate Blunden -- with his neck broken.

What's interesting about all of this is that after the Mayfair story, the whole thing kind of died down.  It's still called "the most haunted house in London," and figures prominently on London ghost tours, but it was purchased in 1937 by Maggs Brothers Antiquarian Book Dealers, and has shown no sign since that time of any paranormal occurrences.  And it's been pointed out that the story The Haunted and the Haunters by Edward Bulwer-Lytton -- published in 1859, right around the time the rumors of the haunting started -- bears an uncanny resemblance to the tale of 50 Berkeley Square, especially the account of the unstable Baron Lyttleton.

In my opinion, the entire thing seems to be spun from whole cloth.  There's no evidence that any of the paranormal stuff ever happened.  In fact, "Sir Robert Warboys" doesn't seem to exist except in connection to the haunted attic; if there is a mention of him anywhere except in accounts of his death at the hands of the misty "Thing," I haven't been able to find it.  As far as "two sailors from Portsmouth," that has about as much factual accuracy as "I heard the story from my aunt who said her best friend in high school's mother's second cousin saw it with her very own eyes."  And Lyttleton, as I've said, doesn't seem like he was exactly the most mentally stable of individuals to start with.

But I have to admit, it's a hell of a scary tale.  Part of what makes it as terrifying as it is is the fact that you never see the phantom's face.  As Stephen King points out, in his outstanding analysis of horror fiction Danse Macabre, there are times when not seeing what's behind the door is way worse than opening the door and finding out what it actually is.  So even though I'm not buying that the place is haunted, it does make for a great story -- and 50 Berkeley Square will definitely be on my itinerary when I have an opportunity to visit London.

Weeping ghosts and hospital demons

It's a phenomenon we've seen here before; the tendency of people to wave photographs around, claiming that they are evidence of the paranormal despite the fact that the image quality is generally lousy (either from magnification and subsequent pixillation, or else from a photograph that wasn't very good to begin with).  Blurry photographs, of course, leave your mind open to interpreting what you're looking at, which is dangerous ground if you're trying to do so skeptically and fairly.  If you add to that a dash of pareidolia, a shot of wishful thinking, and a heaping handful of being told ahead of time what you're seeing, and you've got a nice recipe for proving the existence of ghosts, aliens, Bigfoot, and pretty much whatever else you want.

I ran into two really good examples of that a couple of days ago.  The first one was presented over at The Crypto Crew as being a ghost standing behind a grieving man in a cemetery:


What immediately struck me about this one is that if it hadn't been for the three red arrows, I would never have thought there was anything odd about this photograph in the first place.  Even with the arrows it took me a while to see the "ghost."

A second one has a decidedly darker implication.  I first saw it on Facebook, but have since run into it on Twitter and a couple of the dicier paranormal sites.  It purports to show a dying woman in a hospital bed -- and a demon standing over her, presumably ready to whisk her soul off to hell as soon as she crosses into the netherworld:


Well, even over at Unexplainable.net they're not buying this one, and heaven knows they've had some pretty sketchy stuff over there and haven't raised an eyebrow.  Here's how they parse the Demon Photograph:


What I find most interesting about this is how our brains force an interpretation -- once we've been told that there's a demon there, we see the demon even if (like me) you don't believe in demons in the first place.  Grainy data can be turned into anything -- even, apparently, by skeptics.

It also strikes me how you never get a clear photograph of any of this stuff.  In these days where the average cellphone shot has better resolution than a photograph taken with an expensive camera did twenty years ago, why hasn't anyone been able to take a photograph that shows any real detail?  (Of course, I have a favored answer to this, but it's not one that's popular amongst the woo-woos.)

So that's the latest from the Creepy Photograph Department.  Myself, I think the guys in Quality Assurance need to have a look over there, because things seem to be slipping a little.  Next thing you know, we'll be seeing the folks over at Phantoms & Monsters giving up on paranormal photographs, and at that point we'll really know we're headed to hell in a handbasket.

Just like the poor lady in the hospital bed.

Biblical corn

One of the things I find amusing about people who argue over the meaning of passages in the bible is that so few of them seem to recognize that they're working from a translation.

A few -- very few, in my experience -- people are true biblical scholars, and have worked with the Aramaic and Greek originals (and I use that word with some hesitation, as even those were copies of earlier documents, copied and perhaps translated themselves with uncertain accuracy).  Most everyone else acts as if their favorite English translation is the literal word of god, as if Jesus Christ himself spoke pure, unadulterated 'Murican.

It does give rise to some funny situations.  We have the argument over whether the forbidden fruit that Eve gave Adam was an apple, a fig, or a pomegranate.  We have the claim (Micah 5:2) that the Messiah would be descended from David, and both Matthew and Luke go to great lengths to show that Joseph was a descendant of David (although they disagree on his descent, so they can't both be right) -- and Jesus wasn't Joseph's son in any case.  We have one person who has argued that the creation story was translated wrong, and that god didn't create life, he "separated" humans from everything else, presumably by giving them souls.

We even have some folks who claim -- tongue-in-cheek, of course -- that the line from Leviticus 20 about "if a man lies with another man, they should both be stoned" as biblical support for gay marriage and marijuana legalization simultaneously.

All of which strikes me as funny, because no matter how you slice it, you're still arguing over the meaning of an uncertainly-translated text that has been recopied with uncertain precision an uncertain number of times, and reflects the beliefs of a bunch of Bronze Age sheepherders in any case.  Notwithstanding, you still have people arguing like hell that their translation is the correct, god-approved one, and all of the others are wrong.

And then you have this guy, who takes things a step further, declaring that the translation of one word is correct, and that means that... pretty much everything else we know about the history of the Middle East is wrong.

That word is "corn."

[image courtesy of the Wikimedia Commons]

The word occurs 102 times (in the King James Version, at least) -- mostly as a translation of the Semitic root dagan.  The problem, of course, is that corn is a Mesoamerican plant, and did not exist in the Middle East until it was brought over after the exploration of the New World.  It's very easily explained, though; not only did dagan mean "grain" (not, specifically, corn), the word "corn" itself just meant "grain" in early Modern English -- a usage that persists in the word "barleycorn."

But this guy doesn't think so.  He thinks that the use of the word "corn" means... corn.  As in the stuff you eat at picnics in the summer with lots of butter and salt, the stuff cornmeal and popcorn and corn starch and high-fructose corn syrup are made from.  And therefore, he thinks...

... that everything in the bible actually happened here in the Western Hemisphere.

I'm not making this up.  Here's a direct quote:
The difficult situation with CORN in the BIBLE is that most people, due to the brainwashing that has been handed down through generations, firmly believe that the Biblical events happened in the Middle East.  After much research I can PROVE that the Middle East has absolutely NOTHING to do with the history, geography, and genealogy of the Holy Scriptures.  Nothing!...  CORN is in the Bible because the PEOPLE, PLACES, and EVENTS of the Biblical narratives were in the AMERICAS!
The "true history" of the events of the bible, he says, have been "hidden for over 500 years."  He has proof, which he will tell us when his book is released, and it's gonna overturn everything you think you know about history.

Oh, yeah, and the Crusades happened over here, too.  Apparently the Crusaders didn't trek to Jerusalem, they were trying to retake Peoria or something.

'Murica!  Yeah!

I'm not making this up, and the guy who wrote it seems entirely serious.  But it does highlight what can happen when you decide that any human-created document is the infallible word of a deity, or even (as I've heard) that god guided the translators and copiers so that it still is inerrant even after the inevitable Game of Telephone that translating and copying usually entails.  Not many people go as far as the Corn Dude does -- but it does bring up the question of whether any translation of the bible is good enough that we should even entertain using it as a guide to behavior or (heaven forfend) science.

So that's our exercise in eye-rolling for today.  Me, I'm done with the topic, so I'm going to go get breakfast.

For some reason, I'm in the mood for cornbread.  Funny thing, that.

Shrouded in pseudoscience

I hate to break it to you, LiveScience, but in the interest of accuracy, it's probably time to take the word "Science" out of the name of your website.

What you're promoting isn't really science, any more than The History Channel has anything even remotely to do with history.  You're passing along to the public the idea that science is this mushy, hand-waving pursuit, where you can do an "experiment" to support an idea you'd already decided was true, generate essentially nothing in the way of data, and then claim that your results support whatever your original contention was.

I say this in light of a recent story called "Shroud of Turin: Could Ancient Earthquake Explain Face of Jesus?"  If the very title makes you suspicious, then good; you're starting out from the right vantage point.

Let's begin with the facts.  The Shroud of Turin is a piece of linen cloth that has been preserved for centuries as a holy relic -- supposedly the sheet that covered Jesus' body after the crucifixion.  It shows the image of a naked man, with wounds similar to those described in the bible.

[image courtesy of the Wikimedia Commons]

The problem is, the linen cloth was carbon-14 dated -- a step that the religious powers-that-be resisted for decades -- and it was conclusively shown to date to around 1350 C.E.  It is, put simply, a fake.  So you'd think that would be that.

As we've seen before, that is never that when religion enters the picture.

The article in LiveScience tells about a study headed by Alberto Carpinteri of the Politecnico di Torino, in Turin, Italy, which discovered that when you crush rocks using a mechanical press, it can cause a brief emission of neutrons.  From that single piece of information, he concludes the following:
  • Earthquakes can therefore be associated with neutron emissions.
  • The neutrons could interact with nitrogen atoms in the linen cloth (or in anything else, presumably), and mess up the carbon-14 dating protocol, causing it to give a wrong answer.
  • The neutrons could also have burned a pattern into the cloth as they passed through it.  Because the cloth was wrapped around a human body, it would have caused an image to appear on it, much like an x-ray.
  • The bible says that there was an earthquake around the time of Jesus' resurrection, and the "stone rolled back from the tomb."  [Matthew 28:1-2]
  • So: the Shroud of Turin is actually the burial cloth of Jesus.  Therefore god and the Catholic Church and all of the rest of it.  q.e.d.
Oh, come on, now.  This qualifies as science?  It's about as bad an example of assuming your conclusion as I've ever seen.  And if earthquakes interfered with carbon-14 and nitrogen-14 levels, then radiocarbon dating would never work, since earthquakes happen basically all the time, all over the Earth.  And yet carbon-14 dating has been shown to be extremely accurate, over and over again.

Funny thing, that.

So you have to wonder why Carpinteri et al. don't just say, "It was magic, and I believe it," and be done with it.  Why all of the scientific trappings?

Well, I know the answer, of course; people these days are getting a little iffy in the firmness of their religious convictions, and science is beginning to hold more sway over people's minds than religious authority does.  If you can convince folks that the science supports religion, you've pulled 'em right back in.

To LiveScience's credit, at least they took the time to talk to an actual scientist, geochemist Gordon Cook of the University of Glasgow.  Cook, unsurprisingly, was dubious.  "It would have to be a really local effect not to be measurable elsewhere," Cook said.  "People have been measuring materials of that age for decades now and nobody has ever encountered this."

However, even though they quoted Cook, the fact that LiveScience chose to publicize this non-science means that they're giving it unwarranted credence, and that's just irresponsible.  A "study" like this wouldn't make it through the first round of peer review.  Carpinteri and his team are relying on press statements -- and sites like LiveScience -- to publicize what is, at its heart, a religious statement of faith.

So the whole thing is a little frustrating.  It won't change anything, probably; the scientists will almost certainly just roll their eyes and go back to what they were doing, and the religious people who want to believe in the Shroud's relic status will continue to believe.

But I maintain: LiveScience, The History Channel, The Discovery Channel, and other popularizers of a pseudoscientific worldview are not doing science any favors by convincing the public that this sort of foolishness deserves to be considered seriously.  I'd almost rather that they stick to Bigfoot, UFOs, and pieces about how the Vikings were alien time-travelers.  At least that stuff is mildly entertaining.
