Cup of woo

I was just thinking yesterday that it'd been a long time since I'd seen a good example of the kind of loony New Age woo-woo I seemed to run into on a daily basis when I first started Skeptophilia twelve years ago.  "Maybe," I thought, "people have moved beyond all that nonsense into a more scientific, skeptical, rational way of looking at the world."

Ha ha ha.

By stating that aloud, I must have tapped into some kind of Quantum Vibration Frequency Resonance Field of Actualization, because while idly perusing TikTok not an hour later, I stumbled upon a post from a guy who is like what would happen if you gave Simon Pegg a hit of acid and then told him to do his best impression of Deepak Chopra.

His name is Matt Cooke, and he calls himself a "manifestation coach."  Lest you think I'm exaggerating in my description, here's a transcript of the post in question:

If you understand the power of the quantum field, you hold in your hands the secret of manifestation.  I'm going to simplify what the quantum field means, and how you can use it as a tool to manifest anything in your life.  So quite simply, you'll hear people say either the quantum field or the unified field.  What that basically is is an invisible field of energy carrying information and frequency that is invisible to our five senses but is all around us in space that we can't see.

People say that, do they?  Not scientists, presumably, just "people."  Do go on.

What people don't realize, though, is that we are also an extension of that field, because we're just energy.  The human body is just a dense form of energy moving at a very slow rate of vibration.  We in fact vibrate in and out of the quantum field eight times every second.

I've been in this business long enough that as soon as he said "eight times every second," I immediately knew where he'd gotten that number from, and it wasn't from a Quantum-Field-O-Meter, or anything.  He's almost certainly referring to a woo favorite, the Schumann resonances, which somehow got wrapped up in mystical goofiness despite the fact that it's actually a very real electromagnetic phenomenon.  It's a resonance between the Earth's surface and the conductive layer of the atmosphere (the ionosphere), which has resulted in a standing wave -- an electromagnetic field pulse that has a fundamental frequency of 7.83 Hertz (i.e. just shy of eight times per second).  It's been nicknamed "the Earth's heartbeat," which is an unfortunate choice of phrase (second only to physicist Leon Lederman's choice of "the God particle" as his nickname for the Higgs boson), because it encourages woo-ish types to see the Schumann resonances as being evidence of a global consciousness or whatnot, when in reality, as a phenomenon it's about as conscious as a pendulum swinging on a string.

But back to Cooke:

The way the field works is that it is outside of three-dimensional reality.  It's something called the fifth dimension.

Presumably not related to the people who sang "This is the Dawning of the Age of Aquarius," although you can see how one might be confused on this point.

The fifth dimension quite simply is beyond time.  Time is infinite.  Meaning that if time's infinite, there are endless infinite opportunities that exist right now.  So anything you desire is there electromagnetically.

Right!  Sure!  What?

This is why people never change.  This is why people continue to attract more of the same stuff into their lives.  How we think and how we feel is how attraction works.  A thought is an intention, a feeling is an emotion.  So if right now you are in lack and hating life, subconsciously you are creating those same thoughts and you're feeling the same way.  You're vibrating in and out eight times a second, the field doesn't respond to what you want, it responds to who you're being.  This is why you hear people say, if you want to manifest you need to become it right now.  If you are seeking something right now in your life, if you change how you think and how you feel, you will broadcast a new electromagnetic signature into the quantum field.  Right?  You'll be drawing back to you a new state of being.  Basically, you'll be reprogramming your vibration.  If you change your vibration, you change your personality, and it's your personality, who you are, that creates your outside world.  Your inside world creates your outside world, and that is how the quantum field works.

Allow me to direct your attention to the Wikipedia article on quantum field theory, wherein you will quickly find that this is not, in fact, how the quantum field works.

Look, it seems like this guy's heart is in the right place, and that he honestly wants to help people.  And I certainly like his take on how to make the world a better place more than I do the evangelical Christians' approach, which is to alternate between praising the God of Unconditional Love and smiting the absolute shit out of anyone who is not also an evangelical Christian. 

What bothers me about people like this is that they're trying to gain credence for their claims by adding a scientific, physics-based spin on them, and end up using technical terms in such a bizarre way that large numbers of people now have no idea whatsoever what those terms actually mean.  And I do mean large numbers; Matt Cooke has over 144,000 followers on TikTok.  And he, of course, is small potatoes compared to the champion purveyor of quantum woo, the aforementioned Deepak Chopra, who is so renowned that someone created a Random Deepak Chopra Quote Generator that produces pearls of arcane wisdom so similar to the real thing that I defy anyone to tell the difference.  (Here was mine for today: "Infinity differentiates into the expansion of brains through the activation of love.")

So, by all means, Mr. Cooke, keep trying to help people live their best lives.  But leave the quantum field to the quantum physicists.  It doesn't help your case, and to anyone who has ever taken a college physics course, it makes you sound like a snake oil salesman.  Thanks bunches.

Return to sender

Despite my daily perusal of the news and science sites for interesting topics, sometimes I miss stuff. It's inevitable, of course, but sometimes a story is so absolutely tailor-made for this blog that I can't believe that (1) I didn't see it, and (2) a reader didn't send me a link.

That was my reaction when I ran into, quite by accident, an article from Scientific American several years ago about a researcher in the Netherlands who did a psychological study of people who believe in reincarnation.  I've always found the whole reincarnation thing a bit mystifying, especially given that most of the people you talk to who claim past lives say they were Spartan warriors or Babylonian princesses when, just by the numbers, the vast majority of people should recall being Chinese peasants. Or, if you allow reincarnation from other life forms, being a bug.

But no.  "Boy, life sure was boring, when I was a bug" is something you rarely ever hear reincarnated people say.

Then, there are the people who -- like one person I know who I swear I'm not making up -- believe they are reincarnated from individuals who lived in places that don't, technically, exist.  This particular woman says in a past life she was a "gifted healer and wise woman from Atlantis."  She apparently remembers a lot of what she knew as an Atlantean person, which include pearls like "always strive to bring peace and love to those around you."

Which, honestly, I can't argue with, whether or not you're from Atlantis.

Apparently this study found that there are a great many other people who believe fervently that they were once someone else, somewhere else.  So Maarten Peters, a psychological researcher at Maastricht University in the Netherlands, decided to see if he could figure out what was going on.

He asked for people who believed they could recall past lives to volunteer, and an equal number of people who did not believe in reincarnation, and gave them a test called the false fame paradigm.  This test gives subjects a list of unfamiliar names to memorize, and then the next day those names are mixed in with new names and the names of famous people.  The question was: which of the names presented belong to famous people?

When he compared the results, an interesting pattern emerged.  The people who believed in reincarnation were, across the board, more likely to commit a source-monitoring error -- an error in judgment about the source of a memory.  They were far more likely than the control group to think that the unfamiliar names they had memorized the previous day belonged to famous people.  Evidently, they had a marked tendency to conflate their own (recent) memory of a name with (more distant) memories of hearing about celebrities in the news.

"Once familiarity of an event is achieved, this can relatively easily be converted into a belief that the event did take place," Peters said about his results.  "A next possible step is that individuals interpret their thoughts and fantasies about the fictitious event as real memories."

The implication is that the "memories" these people have about past lives are very likely to be an amalgam of memories of other things -- stories they've read, documentaries they've watched, perhaps even scenarios they'd created.  Whatever's going on, it's extremely unlikely that the memories these people claim to have come from a prior life.

Of course, there's a ton of anecdotal evidence for reincarnation, which in my mind doesn't carry a great deal of weight.  The whole thing has been the subject of more than one scholarly paper, including one in 2013 by David Cockburn, of St. David's University College (Wales), called "The Evidence for Reincarnation." In it, he cites claims like the following:

On March 15th, 1910, Alexandrina Samona, five-year-old daughter of Dr. and Mrs. Carmelo Samona, of Palermo, Sicily, died of meningitis to the great grief of her parents.  Within a year Mrs. Samona [gave] birth to twin girls.  One of these proved to bear an extraordinary physical resemblance to the first Alexandrina and was given the same name.  Alexandrina II resembled Alexandrina I not only in appearance but also in disposition and likes and dislikes.  Stevenson then lists a number of close physical similarities and of shared characteristic traits of behaviour.  For example: Both liked to put on adult stockings much too large for them and walk around the room in them.  Both enjoyed playfully altering people's names, such as changing Angelina into Angellanna or Angelona, or Caterina into Caterana.  Most striking of all, however, were the child's memory claims: 'When Alexandrina II was eight, her parents told her they planned to take her to visit Monreale and see the sights there.  At this Alexandrina II interjected: "But, Mother, I know Monreale, I have seen it already."  Mrs. Samona told the child she had never been to Monreale, but the child replied : "Oh, yes, I went there.  Do you not recollect that there was a great church with a very large statue of a man with his arms held open, on the roof?  And don't you remember that we went there with a lady who had horns and that we met some little red priests in the town?"  At this Mrs. Samona recollected that the last time she went to Monreale she had gone there with Alexandrina I some months before her death.  They had taken with them a lady friend who had come to Palermo for a medical consultation as she suffered from disfiguring excrescences on her forehead.  As they were going into the church, the Samonas' party had met a group of young Greek priests with blue robes decorated with red ornamentation.'

Even though Cockburn is willing to admit reincarnation as a possible explanation of such claims, he sounds a little dubious himself; toward the end of his paper, he writes, "[E]ven if we did think in terms of some underlying common element which explains the similarities between these individuals we would still need to show that the presence of the common element justifies the claim that we are dealing with a single person: to show, that is, what significance is to be attached to the presence of that element."  I would add that we also need to eliminate the possibility of outright lying on the part of the parents -- there has been more than one case where a parent has attempted to hoodwink the public with regards to some purportedly supernatural ability their child allegedly has.

So anyhow.  My sense is that the evidence for reincarnation is pretty slim, and that any claims of past lives are best explained by fallible memory, if not outright lying.  But I'm guessing no one will be surprised that I'm saying that.  In any case, I better wrap this up.  Lots to do today.  Considerably more, I would imagine, than I'd have to do if I was a bug, although that's pure speculation because I don't have much of a basis for comparison.

The gift of a voice

I can think of no more terrifying disorder than locked-in syndrome.

Locked-in syndrome, also called a pseudocoma or cerebromedullospinal disconnection, is a (fortunately) rare condition where the entire voluntary muscle system shuts down but leaves the cognitive facilities relatively intact.  The result: you can't move, speak, or respond, but your brain is otherwise functioning normally.

You are a prisoner inside your own useless body.

The most famous case of locked-in syndrome was French journalist Jean-Dominique Bauby, who suffered a massive stroke at age 43 and lost control of his entire muscular system except for partial control over his left eye.  This at least allowed him to eventually communicate to his doctors that he was still conscious, and -- astonishingly -- he used that tiny bit of voluntary muscular movement to direct a cursor on a computer screen and painstakingly, letter by letter, write a book about his experience.  It's called The Diving Bell and the Butterfly, and it is simultaneously devastating and uplifting -- a paean to the human spirit's ability to rise above a level of adversity that, thankfully, very few of us will ever face.

Thanks to an article last week in IEEE Spectrum, I just found out about a new prosthetic device that will give people who have lost their ability to communicate their voices back -- by converting their brain waves into words.

A team at the University of California - San Francisco has done (successful) clinical trials of a device that is implanted through a small port in the patient's skull, and is able to detect the neural signals the cerebellum and motor cortex send to the patient's larynx and mouth when they think about speaking.  From the encoded electric impulses representing the movements the person would have made, had they been able to speak, the prosthesis is able to produce whole sentences of text -- at eighteen words a minute.

Pretty impressive, especially considering that this was just proof-of-concept, so as the technology is refined, it'll only get better.  And considering that Bauby was communicating at two to three letters per minute, this is an incredible leap forward.

"We’re now pushing to expand to a broader vocabulary," said Edward Chang, who led the team that developed the prosthesis.  "To make that work, we need to continue to improve the current algorithms and interfaces, but I am confident those improvements will happen in the coming months and years.  Now that the proof of principle has been established, the goal is optimization.  We can focus on making our system faster, more accurate, and—most important— safer and more reliable.  Things should move quickly now."

They are also working toward developing a wireless version that would be able to pick up the relevant brain waves from outside, thus obviating the need to place a port in the patient's skull.  With further refinements, it might become possible to create a device that could be used on any individual who is unable to speak -- the present ones require a training period during which they learn the patient's specific neural firing patterns.  Once those are generalized, it might be possible to create a "universal translator," something Chang calls "plug-and-play."

Even what they have now is amazing, however.  Imagine regaining your voice after months or years of muteness.  I never fail to be astonished at the progress we're making in science; it seems like everywhere you turn, there are new discoveries, new inventions, new insights.

In a time when so much seems hopeless, it's wonderful that we have such stories to remind us that there are people who are working to ease the burdens of others -- and that, in the words of Max Ehrmann's beautiful poem "Desiderata," "With all its sham, drudgery, and broken dreams, it is still a beautiful world."

Tut tut

I ran into an interesting article in Science News yesterday about a new museum in Egypt that will feature the famous treasure trove of King Tutankhamun's tomb.  Tutankhamun was, as you undoubtedly know, the pharaoh of Egypt between about 1332 and 1323 B.C.E. before dying at the age of nineteen (probably of complications from malaria).  Because of his short reign and youth he's been nicknamed "the Boy King," and prior to his tomb's discovery in in 1922 held a relatively obscure spot in Egyptian history.  This may have been what saved his tomb nearly intact for archaeologists to find; no one knew it was there.

He was also eclipsed by his infamous father, the Pharaoh Akhenaten, the "heretic king" who attempted to replace the Egyptian pantheon of gods with a single monotheistic religion, the worship of the god Aten.  Trying to decree a change in people's religion went about as well as you'd expect, and after Akhenaten's death everyone went back to worshiping Ra and Horus and Thoth and Anubis and the rest of the gang, not to mention erasing every trace of Akhenaten they could find.

The whole thing, though, put me in mind of the famous "King Tut's Curse," which supposedly claimed the lives of a number of people who investigated the tomb and has since spawned countless movies and horror novels about evil befalling people who violate people's final resting places.

The story goes that shortly after Tut's tomb was opened, people associated with the expedition began to die.  The first was Lord Carnarvon, who had funded Carter's expedition, who cut himself badly while shaving and died shortly thereafter of sepsis from an infection.  While it's easy enough to explain a death from infection in Egypt prior to the advent of modern antibiotics, the deaths continued after the members of the expedition returned to London:

• Richard Bethell, Carter's personal secretary, was found smothered in a Mayfair club.
• Bethell's father, Lord Westbury, fell to his death from his seventh-floor flat -- where he had kept artifacts from the tomb his son had given him.
• Aubrey Herbert, half-brother of the first victim Lord Carnarvon, died in a London hospital "of mysterious symptoms."
• Ernest Wallis Budge, of the British Museum, was found dead in his home shortly after arranging for the first public show of King Tut's sarcophagus.

And so on.  All in all, twenty people associated with the expedition died within the first few years after returning to England.  (It must be said that Howard Carter, who led the expedition, lived for another sixteen years; and you'd think that if King Tut would have wanted to smite anyone, it would have been Carter.  And actually, a statistical study done of Egyptologists who had entered pharaohs' tombs found that their average age at death was no lower than that of the background population.)

Still, that leaves some decidedly odd deaths to explain.  And historian Mark Benyon thinks he's figured out how to explain them.

In his book London's Curse: Murder Black Magic, and Tutankhamun in the 1920s West End, Benyon lays the deaths of Carter's associates in London -- especially Bethell, Westbury, Herbert, and Budge, all of which were deaths by foul play -- at the feet of none other than Aleister Crowley.

Crowley, you may recall, was the subject of a seriocomic post here about a magical battle only a couple of months ago, so he's a bit of a frequent flyer here at Skeptophilia.  For those of you who missed that one, Crowley is the guy who proclaimed himself the "Wickedest Man on Earth," and was a sex-obsessed heroin addict who became notorious for founding a magical society called "Thelema."  Thelema's motto was "Do what thou wilt," which narrowly edged out Crowley's second favorite, which was "Fuck anything or anyone that will hold still long enough."  His rituals were notorious all over London for drunken debauchery, and few doubted then (and fewer doubt now) that there was any activity so depraved that Crowley wouldn't happily indulge in it.

Crowley ca. 1912 [Image is in the Public Domain]

One of Crowley's obsessions was Jack the Ripper.  He believed that the Ripper murders had been accomplished through occult means, and frequently was heard to speak of Jack the Ripper with reverence.  Benyon believes that when Crowley heard about Howard Carter's discoveries, he was outraged -- many of Thelema's rituals and beliefs were derived from Egyptian mythology -- and he came up with the idea of a series of copycat murders to get even with the men who had (in his mind) desecrated Tutankhamen's tomb.

It's an interesting hypothesis.  Surely all of the expedition members knew of Crowley; after all, almost everyone in London at the time did.  At least one (Budge) was an occultist who ran in the same circles as Crowley.  That Crowley was capable of such a thing is hardly to be questioned.  Whether Benyon has proved the case or not is debatable, but even at first glance it certainly makes better sense than the Pharaoh's Curse malarkey.  It's probably impossible at this point to prove if Benyon's claim is correct in all its details, rather like the dozens of explanations put forward to explain the Ripper murders themselves.  But this certainly makes me inclined to file the "Mummy's Curse" under "Another woo-woo claim plausibly explained by logic and rationality."

In any case, I'm glad to hear the archaeologists are still working on the discoveries from Tutankhamun's tomb, and not afraid that they themselves will be struck down by the ghost of the Boy King.  I'll take actual scientific research over loony superstition any day of the week.

Damage control

The human psyche is a fragile thing.

I was going to start that sentence with, "At the risk of being called a snowflake...", but then I decided I don't give a flying rat's ass if anyone does call me a snowflake.  Or "woke."  "Snowflake" has become some kind of jerk code for "someone who cares deeply how others feel," and "woke" for "awareness that others' experience and perceptions are as valid as my own, even if I don't share them," and on that basis I'm happy to accept the appellation of Woke Snowflake.

The fact is, all of us, even Un-Woke Non-Snowflakes, can be hurt.  It's all too easy.  Whether we react to that hurt by crying, retreating, laughing it off, or getting angry, the fact remains that none of us are impervious to what others say and think.  It's why dealing with bullying is so critical, and the correct response is not to tell the victim "toughen up, develop a thicker skin, grow some balls," or whatever, all things I was told repeatedly when I was a child.  Unsurprisingly, none of that sage advice had the slightest effect, other than letting the bullies know that no one was going to do a damn thing about it.  It's amazing the number of people who don't recognize this for what it is, which is a game of "blame the victim."

For what it's worth, the correct response is for someone with appropriate authority to tell the bully, "This stops, and it stops now.  I will be watching you."

It's why when I was asked a while back what were the three most important words you could say to someone other than "I love you," my response was, "You are safe."  I never felt safe when I was a kid.  And if you don't think that leaves a mark on someone that persists into adulthood, you are sadly mistaken.

It's why I was sickened by the revelation this week that British actor Kit Connor, best known for playing the character of Nick Nelson on the lovely coming-of-age series Heartstopper, was being harassed online by "fans" who accused him of "queerbaiting" -- pretending to be queer (or being cagey about it) in order to benefit from the cachet of being associated with the LGBTQ community without committing himself outright.  Connor ignored the accusations for a while, but they became so strident that he got onto Twitter on Halloween and posted:

The number of ways this is fucked up leaves me not knowing where to begin.  Apparently part of the firestorm started with photographs of him holding hands with actress Maia Reficco, which adds a whole nasty gloss of "bi people in straight-presenting relationships aren't actually queer" to a situation that is already ugly enough.  I find this infuriating (for obvious reasons); we bisexual people are under no obligation to meet some kind of queerness litmus test set by someone -- anyone -- else.

The deeper problem here, of course, is that nobody should ever push someone to come out before they're ready.  Ever.  This sort of thing happens all too often with actors and musicians, and not just about sexual orientation but about everything.  Fans become desperate to peer into their lives, as if somehow enjoying their skill, talent, and hard work when they perform justifies forgetting that they are real humans who need privacy and have the right to reveal about their personal lives exactly what, when, and how much they choose.  At the far end of this horrible scale is the phenomenon of paparazzi, parasites who are fed by fans' insatiable appetite for lurid details, accurate or not.

The worst part in this particular case is that the lion's share of the accusations of queerbaiting Connor faced came from people who are LGBTQ themselves.  People who should fucking well know better.  People who themselves have undoubtedly faced harassment and discrimination and unfair social pressures, and now have apparently forgotten all that and turned on someone whose only crimes were (1) playing a bisexual character in a television show, and (2) wanting to come out by his own choice and at his own time.

How dare you force someone into this situation.

I can only hope that Kit's trenchant "I think some of you missed the point of the show" drove the message home with these people.  I also hope that the harm done to Kit himself, and potentially to his relationships (whatever those are), doesn't leave a lasting mark.  To the fandom's credit, there was a huge groundswell of people supporting him unconditionally and decrying what had happened, and with luck, that did enough damage control to lessen the pain he endured.

So for heaven's sake, people, start thinking before you speak, and realize that words can do incalculable harm.  Keep in mind that humans are fragile creatures who deserve careful handling.  Always err on the side of compassion.

And if you can't do all that, then at least have the common decency to keep your damn mouth shut.

Exploding the birth-order myth

How often have you heard a friend mention an odd characteristic of a mutual acquaintance, and follow it up with a statement like, "Well, he's a middle child," leaving you both nodding knowingly as if that explained it?

Conscientious, strong-willed eldest children.  Lost, rebellious middles.  Immature, demanding youngests.  Then there's my situation -- the spoiled, tightly-wound only children, who were doted upon by their parents and had their every whim met immediately.

I know that wasn't really true in my case; far from being overprotected, my youth was more a case of free-range parenting of a child who was damn close to feral.  After school, and all summer long, my parents' style could be summed up as "Be back by dinner and try not to break any bones.  Either yours or anyone else's."  So I knew that at least from a sample size of one, there was something wrong with the birth-order-determines-personality model.

Even seeing other exceptions here and there never left me confident enough to contradict the prevailing wisdom.  After all, the plural of anecdote is not data.  But now a pair of studies has conclusively disproven the connection between birth order and... anything.

In the first, a trio of psychologists at the University of Leipzig analyzed personality assessments for a huge sample size (they had data for over 20,000 individuals), looking for how they scored on what are called the "Big Five" features of personality -- extraversion, emotional stability, agreeableness, conscientiousness, and imagination.  They found no correlation whatsoever between birth order and any of those. In their words:

[W]e consistently found no birth-order effects on extraversion, emotional stability, agreeableness, conscientiousness, or imagination.  On the basis of the high statistical power and the consistent results across samples and analytical designs, we must conclude that birth order does not have a lasting effect on broad personality traits outside of the intellectual domain.

A similar, but much larger study done at the University of Illinois -- this one of 377,000 high school students -- also found no correlation whatsoever:

We would have to say that, to the extent that these effect sizes are accurate estimates of the true effect, birth order does not seem to be an important consideration for understanding either the development of personality traits or the development of intelligence in the between-family context.  One needs only to look at the “confounds,” such as parental socio-economic status and gender, for factors that warrant much more attention given the magnitude of their effects relative to the effects of birth order.

So if there really is nothing to the birth-order effect, why is it such a persistent myth?  I think there are two things going on, here.  One is that during childhood, older children differ in maturity from their younger siblings because... well, they're older.  Of course a fifteen-year-old is going to be more conscientious and articulate than his seven-year-old brother.  There'd be something seriously wrong if he weren't.  So we tend to see any differences that exist between siblings and interpret them in light of the model we already had, thus reinforcing the model itself -- even if it's wrong.

Because that's the second problem -- our old arch-nemesis confirmation bias.  Once we think we know what's going on, our confidence in it becomes unshakable.  I have to wonder how many people are reading this post, and thinking, "Yes, but for my own kids, the birth-order effect works.  So I still believe it."  It's a natural enough human tendency.

On the other hand, I think you have to admit that your own personal family's characteristics really aren't going to call into question a scholarly analysis of 377,000 people.

So that's pretty much that.  No more blaming your appreciation of fart jokes on being an immature youngest child.  And my friends and family will have to cast around for a different explanation for why I'm as neurotic as I am.  There probably is an explanation, but my being an only child isn't it.

The dynamic Earth

The highlight of my trip to Iceland this past August was seeing the newly-erupting volcano of Fagradalsfjall, southwest of the capital city of Reykjavík.

Fagradalsfjall is Icelandic for "mountain of the beautiful valley."  I'm not sure I'd use the word "beautiful," which to me carries connotations of "benevolent."  When we were there, you could feel the eruption before you heard or saw it; the entire floor of the valley was vibrating, a subsonic rumble that I felt in my gut.  Then you hear the roar, a guttural, low-pitched thunderous booming.  Then you smell it -- the characteristic sulfurous, rotten-egg smell of an active volcano.  Then you crest the top of a low hill, and see it for the first time.

We were close enough that we could feel the warmth radiated from the lava.  Much closer, and the combination of the heat and the sulfur gases would have been overwhelming.  Orange-hot plumes of molten rock exploded out of the fissure and splattered onto the sides of the cinder cone, almost instantly turning to shattered, jagged chunks of black basalt as it cooled and hardened.

It was one of the most spectacular things I've ever witnessed.  In the presence of this kind of power, you truly feel tiny and very, very fragile. 

We were really extraordinarily lucky to see what we did; we were there on the 15th of August, and -- for reasons unknown -- the eruption abruptly ceased on the 21st.  Fagradalsfjall is still very much an active volcano, though.  Just last week it started up again, and this cycle looks like it may actually be even more dramatic.

What brings all this up is a paper last week in Nature about some research out of the University of California - Santa Barbara that analyzed the lava from Fagradalsfjall and found that it ran counter to the conventional model of how volcanoes erupt.  The previous understanding was that magma chambers fill gradually, and undergo mixing from convection and the physical shaking from earthquakes; then, when the eruption happens, the chamber drains.  This would result in a relatively uniform chemistry of the rock produced from the beginning of the eruption to the end.

That's not what geologists saw with Fagradalsfjall.

"This is what we see at Mount Kilauea, in Hawaii," said Matthew Jackson, who co-authored the study.  "You'll have eruptions that go on for years, and there will be minor changes over time.  But in Iceland, there was more than a factor of 1,000 higher rates of change for key chemical indicators.  In a month, the Fagradalsfjall eruption showed more compositional variability than the Kilauea eruptions showed in decades.  The total range of chemical compositions that were sampled at this eruption over the course of the first month span the entire range that has ever erupted in southwest Iceland in the last 10,000 years."

Why this happened is uncertain.  It could be that Fagradalsfjall is being fed by blobs of liquid magma rising from much deeper in the mantle, where the chemistry is different; those much hotter blobs then rose to the surface without a lot of mixing, resulting in a dramatic alteration of the rock being produced over the course of the eruption.  This adds a significant complication to interpreting records of past eruptions, not only in Iceland, but with other volcanoes.

"So when I go out to sample an old lava flow, or when I read or write papers in the future," Jackson said, "it'll always be on my mind: This might not be the complete story of the eruption."

It's fascinating that as far as science has come, we still have a lot to work out -- not only out in the far depths of space (as yesterday's post about MoND described) but right beneath our feet on our own home world.  As eminent astrophysicist Neil de Grasse Tyson put it, "You can’t be a scientist if you’re uncomfortable with ignorance, because scientists live at the boundary between what is known and unknown in the cosmos.  This is very different from the way journalists portray us.  So many articles begin, "Scientists now have to go back to the drawing board."  It’s as though we’re sitting in our offices, feet up on our desks—masters of the universe—and suddenly say, "Oops, somebody discovered something!"  No.  We’re always at the drawing board.  If you’re not at the drawing board, you’re not making discoveries."
