Apocalypse yesterday

I find it simultaneously amusing and terrifying how steeped in self-delusion some folks are.

Now, it's not that I think I'm always right, or free from biases.  Those of you who are regular readers of Skeptophilia will no doubt be aware of my opinion of the accuracy with which our brains function; I'm no more immune to getting things wrong than anyone is.  But still, one thing the scientific, rationalistic point of view does have is a clear protocol for figuring out when you are wrong.  At that point, you have no choice but to reconsider the theory in question.

But some people work the whole thing backwards.  It brings to mind the wonderful quote from Doctor Who in the episode "The Hand of Fear," in which the Fourth Doctor says, "The very powerful and the very stupid have one thing in common: they don't alter their views to fit the facts, they alter the facts to fit their views."

And at that point their altered facts, miraculously enough, always seem to support their model.  So without any apparent realization that they've just committed circular reasoning, they announce that their claim is vindicated.

Perhaps you remember the whole nonsense ten years ago about the Rapture, that came into the news largely because of the late Harold Camping, extremist religious wingnut extraordinaire.  Camping, you might recall, announced a date for the Rapture, and stated his case so vehemently that more than one of his followers sold all of their belongings and gave away the proceeds, or else used the money to purchase billboard space to warn the rest of us that the End Was Near.  The day before the Day, many of them bid tearful farewells to their loved ones, promising to say a good word in Jesus's ear on their behalf after all the dust settled.

Then, the next day, nothing happened.

So Camping revised his prediction to a new date, six months later.  This time he was right, he said, cross his heart and hope to vanish.  But once again, the faithful stayed put on Earth, and worse still, the Antichrist never showed.  So Camping closed up shop, and two years later, died of a stroke at the ripe old age of 92, disappointed to the last that he hadn't lived to see the Rivers Running Red With The Blood Of Unbelievers.  What fun that would have been!

You'd think that sort of failure record (100%) would be a little discouraging to the faithful, wouldn't you?  We keep having predictions of the End Times, and the world refuses to cooperate, and end already.  No Beasts appear, no Antichrist, no Seven Seals; everything just kind of keeps loping along as usual.  Eventually, you'd think people would say, "Hey, you know what?  Maybe we need to reconsider all of this apocalyptic stuff, because so far, it's running a zero batting average."

But no.  They'd never let a little thing like no results change their minds.  And now we have a guy who takes the alter-the-facts approach and pushes it to its ultimate endpoint: he says that the Rapture did too happen, and if you didn't notice, it was your own damn fault.

I'm not making this up.  According to the website Now the End Begins, the holy actually did get Raptured.  Millions are missing, the site says:
Well, we told you it was coming.  Perhaps you were a casual reader of this site, but never got really involved, "too many religious nuts" you said.  Maybe you had a family member who would plead with you night after night to "get right" with Jesus before His return.  "Nah, never happen", you said, "people been saying that for ever. Nonsense!".  But, it wasn't nonsense, was it?  Turns out the religious nuts were right after all.  The Rapture of the Church actually happened.  Now we are gone, and you remain.  Left behind.  I can only imagine the shock - terror - panic - and questions that must be running through your head right now.  My heart breaks for you, and that's why I made this page, to get you through what the Bible calls the time of Jacob's Trouble, the Great Tribulation, and it's moments away from starting.  Are YOU ready?
I... what?

What do you mean "we are gone?"  If you're gone, who is writing for and maintaining the site?  Are you suggesting that Heaven has WiFi and a fast internet connection?  Is the server hosted by the Lord of Hosts?  What do you do if Christ wants to use the Holy Computer while you're updating the website?  Do you tell him, "I'm sorry, Jesus, but you'll have to surf the web another time?"

But my main objection is, if all of those people really had disappeared, don't you think someone would have noticed by now?  Sure, the website tells us.  We all did notice.  And apparently, we're all pretty puzzled about it:
And that's exactly what just happened, and where we have now gone.  Oh, knowing the media as I do, I am sure that there are many attempts to explain it - UFO's, alien abductions, a harmonic convergence, a government program, FEMA camps, cosmic shift, worm holes, and the list goes on and on.  But none of those explainations [sic] really satisfy you, do they?  I mean, it's hundreds upon hundreds of millions of people, right?  Could any one government, no matter how corrupt, really process that many people in the "blink of an eye".  No, they could not.  You know better than that.
I do?  I mean, yes, of course I do.  I'd never fall for the media telling me that hundreds of millions of people were sucked into a wormhole!  That'd just be silly!  I'll believe instead that hundreds of millions of people vanished, and no one has mentioned it in the media at all!

Because, of course, the teensy little problem with all of this is that everyone seems to kind of... still be here.  While I understand that given the circles I travel in, it's understandable that none of my immediate friends and family were Bodily Assumed Into Heaven, you'd think that at least one or two casual acquaintances would be amongst the hundreds of millions who were holy enough to be Raptured.  Strange to say, I haven't noticed anyone in my community vanishing lately.  I really don't think that I'd have missed something like that.  There are even a few I can think of that I'd be happy enough to wave goodbye to, as they floated off into the sky, but no such luck.

The rest of the site consists of suggestions about what to do now that we've been Left Behind (number one piece of advice: don't accept the Mark of the Beast).  But all of that really pales by comparison to the opening bits, wherein they tell us that the Rapture happened while we were otherwise occupied, and we Ungodly Types have yet to notice.

I've said before about the extremely religious that they'll never let a little thing like facts stand in the way of their beliefs, but this may be the best example yet.  The whole thing reminded me of the words of George Aiken, Republican senator from Vermont, who said, when it became obvious that the United States was losing the Vietnam War, "The best policy is to declare victory and leave."  Or in this case, don't let the fact that the Rapture didn't happen interfere with your conviction that the Rapture has actually happened.

Bringing to mind a final quote, this one from George Orwell's 1984: "The Party told you to reject the evidence of your own eyes and ears.  It was their final, most essential command."

Me, I'm just going to do what the world does, namely, keep moseying along and not worry about it.  Even if the UltraChristian crowd is right, I'm pretty certain to be Left Behind anyhow, a possibility that doesn't scare me much.  I've read the Book of Revelation more than once, and I have to point out that whatever else you can say about it, the apocalypse sounds interesting.  There's the Scarlet Whore of Babylon and the Beast with Seven Heads and the Star Wormwood and the Four Apocalyptic Horsepersons and various other special offers from the God of Love and Mercy, any one of which would certainly alleviate the boredom around here.  So if the Rapture really has already happened, let's get this apocalyptic ball rolling, okay, people?  The End Times are a-wastin'.

One of the most devastating psychological diagnoses is schizophrenia.  United by the common characteristic of "loss of touch with reality," this phrase belies how horrible the various kinds of schizophrenia are, both for the sufferers and their families.  Immersed in a pseudo-reality where the voices, hallucinations, and perceptions created by their minds seem as vivid as the actual reality around them, schizophrenics live in a terrifying world where they literally can't tell their own imaginings from what they're really seeing and hearing.

The origins of schizophrenia are still poorly understood, and largely because of a lack of knowledge of its causes, treatment and prognosis are iffy at best.  But much of what we know about this horrible disorder comes from families where it seems to be common -- where, apparently, there is a genetic predisposition for the psychosis that is schizophrenia's most frightening characteristic.

One of the first studies of this kind was of the Galvin family of Colorado, who had ten children born between 1945 and 1965 of whom six eventually were diagnosed as schizophrenic.  This tragic situation is the subject of the riveting book Hidden Valley Road: Inside the Mind of an American Family, by Robert Kolker.  Kolker looks at the study done by the National Institute of Health of the Galvin family, which provided the first insight into the genetic basis of schizophrenia, but along the way gives us a touching and compassionate view of a family devastated by this mysterious disease.  It's brilliant reading, and leaves you with a greater understanding of the impact of psychiatric illness -- and hope for a future where this diagnosis has better options for treatment.

My little... Satan

About a year ago, I got into a fairly surreal conversation with a friend of mine over the phenomenon of "Bronies."

A "Brony," for those of you unfamiliar with the term, is an adult, usually male, fan of the television show My Little Pony: Friendship is Magic.  At first my friend didn't believe that there was such a thing, and she accused me of trying to convince her of something ridiculous so that I would have ammunition for teasing her later when she found out that it wasn't true.

This forced me to dig up an article in Wired from all the way back in 2011 that proved to her that, unlikely as it may seem, the Brony phenomenon is real.

The Bronies are pretty serious about their obsession, too.  They have conventions, and dress up as characters like Fluttershy and Twilight Sparkle and Rainbow Dash, complete with wigs and costumes that are colors not found in nature.

They collect action figures.  They have online discussion groups wherein they discuss the events in recent episodes with the same gravitas you would expect if the scripts had been penned by Shakespeare, or at the very least, George R. R. Martin.  They make fan art (as of the writing of the Wired article, the site DeviantArt had over 90,000 pieces of My Little Pony-inspired art; heaven alone knows how many there are now).  They went so apeshit when My Little Pony: Friendship is Magic ended its run in 2019 that EntertainmentOne and Boulder Media teamed up with Paramount Pictures to produce a full-length movie called, I kid you not, My Little Pony: A New Generation, which is scheduled to be released this September.

There is also a subgroup which apparently like to dress up as My Little Ponies and then have sex with each other.  Which I guess is harmless enough if everyone involved is a consenting adult, but open-minded as I am, I really didn't want to investigate further.

Being an author, my internet search history is already fucked up enough as it is.

Anyhow, after discussing the whole phenomenon with my friend, I got to thinking about it, and I decided that I had to see if I could figure out why this show had gained so much popularity amongst adults.  And fortunately, the article linked above has a short clip from one of the shows.  "Who knows?" I thought.  "I'm an open-minded guy, and confident in my own masculinity.  Maybe I'll be charmed.  Maybe I'll understand how some dude could get taken in by the innocent delight of entering a pastel-colored world where stories always end well."

So I watched the clip.  And "delight" is not what I experienced.  All I can say is, the voices of the My Little Pony characters reach a level of Annoying Whine previously achieved only by the actors who voiced the little dinosaurs in The Land Before Time.  After watching ten seconds of the clip, I wanted to remove my ears, with a cheese grater if need be.  I not only cannot understand how anyone could become a Brony, I felt like I needed to chug a six-pack of Bud Light after watching the clip just to restore order to the universe.

But all of this is backstory.  Because just yesterday I found out, through a different YouTube clip that you all must watch, that there is a reason that otherwise normal guys become Bronies.  And after watching the clip, I realized what a narrow escape I had.

Because My Little Pony is rife with symbolism of Satan and the Illuminati.

From Princess Celestia, who watches the world with the Eye of Horus and is actually a pagan sun goddess; to Applejack, whose apple symbol represents the Apple of the Tree of the Knowledge of Good and Evil; to Twilight Sparkle's six-pointed star.  All symbols of evil magic and the occult.

And don't even get me started about "Pinkie Pie."

All through the video, which is eight minutes long, there is eerie, atmospheric music playing, sort of like the soundtrack to The Exorcist only less cheerful.  I watched the whole thing through twice, because it's just that wonderful.  There are all sorts of references to the Masons and the Satanists and the Illuminati and the Pagans.  An especially great part is where the subtitles tell us that there are six Pony characters, and each one has her own "magic element" and her own color, and 6+6+6 = 666.

I always thought that 6+6+6 = 18.  Maybe it's special Illuminati math or something.

Be that as it may, I guess that this explains the whole "Brony" phenomenon.  Adult guys are getting sucked in by the evil magic of My Little Pony, and through the wicked influence of characters like "Rainbow Dash" they are being induced to dedicate their lives to worshiping Satan.

So it's a truly awesome video, and very educational, although I would caution you against drinking anything while watching it unless you really want to buy a new computer monitor.

Anyway, there you have it.  Why guys become Bronies.  Me, I'm still not likely to watch, even now that I know that the show has a darker side.  Those voices are just beyond anything I could tolerate.  Not that this will convince my friend, who still thinks I'm covering up a secret obsession, to the point that she got me a "Pinkie Pie" mug for my last birthday.

But it could be worse.  She could have gotten me a plush toy with a voice box.  And then I might have made a deal with Satan just to get even with her.

The catastrophe clock

The human brain is a pattern-seeking machine.

We are evolved to look for correlations, probably because those correlations can be awfully useful.  Our habit of noticing patterns and cycles allowed the ancient Egyptians to figure out the timing of the Nile floods, essential for agriculture in a place that was (and is) a desert.  The people of east Africa did the same sort of thing with the monsoons.  In cool climates, knowing when the growing season was likely to start and end was absolutely critical.

The problem is, this same pattern-seeking feature can trick us into seeing illusory patterns in what are, in essence, random data.  Astrology relies on this sort of thing; a particularly common example recently is the freakout people have when Mercury goes into retrograde (an apparent backward motion of Mercury as seen from Earth because of their relative motion; obviously, Mercury doesn't actually start moving backwards).  Supposedly the whole world goes haywire when Mercury starts its retrograde motion, but believing this requires ignoring the fact that (1) Mercury goes into retrograde three or four times a year, for three or four weeks at a stretch, and (2) the world is kind of haywire all the time.  There's no reason to believe that humanity is any loonier during Mercury retrograde than it is at any other time of the year.

Sometimes those illusory patterns can be oddly convincing.  I remember when I was a kid that much was made of the strange coincidence that since William Henry Harrison was elected President of the United States in 1840, every presidential winner in a "zero year" has died in office: Harrison (1840), Lincoln (1860), Garfield (1880), McKinley (1900), Harding (1920), and Kennedy (1960).  Then Reagan (1980) and G. W. Bush (2000) stubbornly refused to die, forcing True Believers to come up with some kind of nonsense about how it was a 120-year curse and expired after JFK's assassination, or something.  Mostly, though, they just retreated in disarray, because it was a peculiar coincidence, not an actual meaningful pattern.

Fortunately, scientists have statistical methods for determining when you're looking at an actual pattern (i.e., whatever is happening occurs with a true cyclicity) and when you're just seeing random fluctuations or scatter in the data.  This can sometimes uncover odd patterns that are clearly real, but result from some as-yet unknown cause -- such as the natural disaster "heartbeat" that was the subject of a paper in Geoscience Frontiers last week.

Geologists Michael Rampino and Yuhong Zhu (of New York University) and Ken Caldeira (of the Carnegie Institution for Science) analyzed the timing of various major geologic events over the past 260 million years -- continental flood basalt eruptions, changes in the direction of plate movement, oceanic anoxia, major glaciations and changes in sea level, and mid-plate volcanism, as well as events like mass extinctions.  And they found that there was a statistically significant cyclicity to those events -- they tend to cluster every 27.5 million years, and have done so for hundreds of millions of years.

But detecting a pattern is not the same as determining what's behind it.  There is no known geological or astronomical event that occurs on a 27.5 million year cycle that might be the underlying cause of the periodic nature of catastrophes.  The authors throw out a few suggestions -- that it could be due to the motion of the Solar System relative to the rest of the Milky Way (oscillating above and below the plane of the galaxy, perhaps?), a thus-far unknown phenomenon originating in the motion of magma in the Earth's mantle, or the gravitational disturbance of the Oort Cloud by a massive, extremely distant planet orbiting the Sun.  (This latter idea has been around for a while; my college astronomy professor, Daniel Whitmire, was one of the first to treat it seriously, and he and his colleague John Matese wrote one of the first scholarly papers about the "Planet X" hypothesis.  But don't even start with me about Nibiru and the Annunaki, because I don't want to hear it.)

The upshot of it is we don't know.  But if you were worried, we're only about 7.5 million years past the last peak, so we have another twenty million or so years to go before the next one.  As optimistic as I am about my longevity, I seriously doubt I'll be around to see it.  The catastrophe clock has a lot of ticks left until the alarm goes off.

Which is a good thing.  As interesting as they are, flood basalt eruptions and oceanic anoxia and the rest are not events that would be fun to witness first-hand.

Why do we have emotions?

It's a tougher question than it appears at first.  Emotions like joy and camaraderie can certainly act to strengthen social bonds; fear can warn us away from dangerous situations.  But how often do they get in the way?  The gray emotional vacuum of depression, the overwhelming distress of anxiety and panic disorder, and the unreasoning terror of phobias can be debilitating enough to prevent anything like normal day-to-day functioning.

In Projections: A Story of Human Emotions by Stanford University professor of bioengineering and psychiatry Karl Deisseroth, we take a look at case studies of emotions gone awry -- in Deisseroth's words, "using the broken to illuminate the unbroken."  His deeply empathetic and utterly fascinating account takes the reader through what can go wrong in our emotional systems, and the most recent, cutting-edge research in how the neurological underpinnings of our brains create our emotional world.

It is brilliant reading for anyone wanting to know more about where our feelings come from, and who seek to follow the ancient Greek maxim of γνῶθι σεαυτόν -- "know thyself."

Hand-in-glove

One of the more fascinating bits of biochemistry is the odd "handedness" (technically called chirality) that a lot of biological molecules have.  Chiral molecules come in a left-handed (sinistral) and a right-handed (dextral) form that are made of exactly the same parts but put together in such a way that they're mirror-images of each other, just like a left-handed and right-handed glove.

Where it gets really interesting is that although the left-handed and right-handed forms of biologically active molecules have nearly identical properties, they aren't equivalent in function.  Nearly all naturally-occurring sugars are right-handed; amino acids, on the other hand, are all left-handed.  No one knows why this is, but having evolved with this kind of specificity has the result that if you were fed a mirror-image diet -- left-handed glucose, for example, and proteins made of right-handed amino acids -- you wouldn't be able to tell anything apart by its smell or taste, but you would proceed to starve to death because your cells would not be able to metabolize molecules with the wrong chirality.

Chirality in amino acids [Image is in the Public Domain courtesy of NASA]

Molecular chirality was used to brilliant effect by the wonderful murder mystery author Dorothy Sayers in her novel The Documents in the Case.  In the story, a man dies after eating a serving of mushrooms he'd picked.  His friends and family are stunned; he'd been a wild mushroom enthusiast for decades, and the fatal mistake he apparently made -- including a deadly ivory funnel mushroom (Clitocybe dealbata) in with a pan full of other edible kinds -- was something he never would have done.

The toxic substance in ivory funnels, the alkaloid muscarine, is -- like many organic compounds -- chiral.  Naturally-occurring muscarine is all left-handed.  However, when it's synthesized in the lab, you end up with a mixture of right- and left-handed molecules, in about equal numbers.  So when the contention is made that the victim hadn't mistakenly included a poisonous mushroom in with the edible ones, but had been deliberately poisoned by someone who'd added the chemical to his food, the investigators realize this is the key to solving the riddle of the man's death.

Chiral molecules have another odd property; if you shine a beam of polarized light through a crystal, right-handed ones rotate the polarization angle of the beam clockwise, and left-handed ones counterclockwise.  So when an extract from the victim's digestive tract is analyzed, and a polarized light beam shined through it splits in two -- part of the beam rotated clockwise, the other part counterclockwise -- there's no doubt he was poisoned by synthetic muscarine, not by mistakenly eating a poisonous mushroom.

Turns out there may be a way to use this hand-in-glove property of biological molecules not to solve a murder, but to detect life on other planets.  As with Dorothy Sayers's synthetic muscarine, organic compounds not produced by a living thing would almost certainly be a mixture of the two chiralities, right- and left-handed.  Because organisms here on Earth are all so incredibly specific about which chirality they need (or create), it's a fair guess that living things on other worlds would have the same choosiness.  And now a technique has been developed to detect molecular chirality in the light reflected from a forest from two kilometers away, by a spectropolarimeter on a helicopter flying at seventy kilometers per hour.

It only took seconds for the detector to tell the difference between light reflected from a living thing and light reflected from something inanimate, like a rock face or an asphalt road.  Now that we're becoming increasingly good at seeing the faint light reflected from the surface of exoplanets, looking for rotation of the polarization angle of that light might be a quick way to see if there's anything alive down there.

"The next step we hope to take is to perform similar detections from the International Space Station (ISS), looking down at the Earth," said astrophysicist Brice-Olivier Demory of the University of Bern and MERMOZ (Monitoring planEtary suRfaces with Modern pOlarimetric characteriZation).  "That will allow us to assess the detectability of planetary-scale biosignatures.  This step will be decisive to enable the search for life in and beyond our Solar System using polarization."

Which is really cool, although as an aside someone needs to explain to whoever is in charge of MERMOZ how acronyms work.

In any case, the whole idea is brilliant, and the possibility that we could detect living organisms on a distant planet just by analyzing the reflected light polarization is mind-boggling.  It's long been the stumbling block in the search for extraterrestrial life; if a planet hosts life, but the living things there are pre-technological, how would we know they're there?  After all, as little as two centuries ago, intelligent aliens would have detected no radio signals coming from Earth, and (of course) we wouldn't have had the capability of detecting any they sent us.

But now, maybe we can tell if there's something alive out there without it having to communicate with us directly.  Like Dorothy Sayers's intrepid detectives, all we have to do is see if the light twists in only one direction, and it might well be case closed.

The moral of the story

I was asked an interesting question yesterday, that I thought would make a great topic for this week's Fiction Friday: does a good story always have a moral?

My contention is even stories that are purely for entertainment still often do have morals.  Consider Dave Barry's novel Big Trouble, a lunatic romp in south Florida that for me would be in the running for the funniest novel ever written.  Without stretching credulity too much, you could claim that Big Trouble has the theme "love, loyalty, and kindness are always worth it."  Certainly the humor is more the point, but the end of the story (no spoilers) is so damn sweet that the first time I read it, it made me choke up a little.

Another favorite genre, murder mysteries, could usually be summed up as "murdering people is bad." 

But that's not what most people mean by "a moral to the story."  Generally, a story with a moral is one where the moral is the main point -- not something circumstantial to the setting or plot. 

The moral is the reason the story was written.

I'm a little ambivalent about overt morals in stories.  I've seen it done exceptionally well; Thornton Wilder's amazing The Bridge of San Luis Rey is explicitly about a man trying to find out if things happen for a reason, or if the universe is simply chaotic.  His conclusion -- that either there is no reason, or else the mind of God is so subtle that we could never parse the reason -- is absolutely devastating in the context of the story.  The impact on me when I first read it, as an eleventh grader in a Modern American Literature class in high school, turned my whole worldview upside down.  In a lot of ways, that one novel was the first step in shaping the approach to life I now have, forty-odd years later.

If I can be excused for detouring into my favorite television show, Doctor Who, you can find there a number of examples of episodes where the moral gave the story incredible impact.  A couple that come to mind immediately are "Midnight," which looked at the ugly side of tribalism and the human need to team up against a perceived common enemy, and "Silence in the Library," with a subtext of the terrible necessity of self-sacrifice.

But if you want examples of bad moralistic stories, you don't have to look any further.  In the most recent incarnation of the Doctor, the episode "Orphan 55" pissed off just about everyone -- not only because of the rather silly cast of characters, but because at the end the Doctor delivers a monologue that amounts to, "Now, children, let me tell you how all this bad stuff happened because humans are idiots and didn't address climate change."


So what's the difference?

In my mind, it all has to do with subtlety -- and respect for the reader's (or watcher's) intelligence.  A well-done moral-based story has a deep complexity; it tells the story and then leaves us to see what the lesson was.  Haruki Murakami's brilliant and heartbreaking novel Colorless Tsukuru Tazaki is about what happens when people are in a lose-lose situation -- and that sometimes a terrible decision is still preferable when the other option is even worse.  But Murakami never comes out and says that explicitly.  He lets his characters tell their tales, and trusts that we'll figure it out.

Bad moral fiction -- often characterized as "preachy" -- doesn't give the reader credit for having the intelligence to get what's going on without being walloped over the head repeatedly by it.  One that immediately comes to mind is Ayn Rand's The Fountainhead, which is so explicitly about Big Government Is Bad and Individualism Is Good and Smart Creative People Need To Fight The Man that she might as well have written just that and saved herself a hundred thousand words.

I think what happens is that we authors have an idea what our stories mean, and we want to make sure the readers "get it."  The problem is, every reader is going to bring something different to the reading of a story, so what they "get" will differ from person to person.  If that weren't the case, why would there be any difference in our individual preferences?  But authors need to trust that our message (whatever it is) is clear enough to shine through without our needing to preach a sermon in a fictional setting.  Stories like "Orphan 55" don't work because they insult the watcher's intelligence.  "You're probably too dumb to figure out what we're getting at, here," they seem to say.  "So let me hold up a great big sign in front of your face to make sure you see it."

A lot of my own work has an underlying theme that I'm exploring using the characters and the plot, but I hope I don't fall into the trap of preachiness.  Two of my most explicitly moralistic tales, the short stories "Last Bus Stop" and "Loose Ends" (both available in my collection Sights, Signs, and Shadows), are about the fragility of life and how we should look after each other because we never know how long we have -- but I think in both cases the moral comes out of the characters' interactions organically, not because I jumped up and down and screamed it at you.

But it can be a fine line, sometimes.  Like I said, we all have different attitudes and backgrounds, so our relationship to the stories we read is bound to differ.  There are undoubtedly people who loved "Orphan 55" and The Fountainhead, so remember that all this is just my own opinion.  

And maybe that's the overarching moral of this whole topic; that everyone is going to take away something different.  After all, if everyone hated explicitly moralistic stories, the Hallmark Channel would be out of business by next week.

Megarhino

Yesterday, we dealt with how freaking huge the universe is.  Today, we're going to look at something that, on its own scale, is also freaking huge.  

Paleontologists working at a site in the Linxia Basin, in Gansu Province in northwestern China, found a skull and spine of what appears to be the largest land mammal that ever walked the Earth.  Called Paraceratherium, this thing was distantly related to modern rhinos, something that is apparent from the artist's reconstructions of what it may have looked like, except for being (1) hornless and (2) absolutely enormous, even by rhinocerosian standards.

Paraceratherium stood five meters tall at the shoulder.  That means if you took a typical twelve-foot extension ladder and propped it against one (Caution!  Do Not Try This At Home!), climbed to the top and reached as high as you could, you'd maybe be able to pat it on the back.  Its head was about seven meters off the ground, and it was on the order of eight meters long from nose to butt.

It's estimated to have weighed 24 tons, which for reference, is about as much as six full-grown African elephants.

I don't know about you, but to me that is staggering.  Think of how much energy that thing used just to walk.  Think of the booming sounds it made when it set its feet down.  Think of how loud the vocalizations of that thing could have been.

Also, think about the piles of dung it must have left around.  "It's your turn to pooper-scoop the Paraceratherium" must have been a devastating thing to hear, back then.

Fortunately, there were no humans around to worry about such matters.  Paraceratherium lived during the Oligocene Epoch (between 34 and 25 million years ago), a time when a lot of groups of mammals got really large -- no one knows why, although there does seem to be a tendency for selection toward large body size when the climate is clement and there's plenty of food.  Also, this was the peak of recovery from the devastating Paleocene-Eocene Thermal Maximum, a climatic spike that had occurred about twenty million years earlier and which coincided with worldwide oceanic anoxia and widespread extinctions, so there was very high biodiversity, and probably equally high competition between species in similar niches.

In any case, that's the current holder of the "Largest Land Mammal Ever" award.  Given how stupendous they must have looked, it's sad they became extinct, although maybe it's just as well.  Imagine what it'd be like with these behemoths stomping around.  We have enough problems keeping deer out of our vegetable garden, I don't even want to think about how we'd keep out a Paraceratherium looking for a quick snack.

The cosmic whirligig

It seems like whenever I look at the realm of the very large or the very small, I quickly get overwhelmed by scale.

I remember, for example, when a teacher in high school was trying to impress upon us kids how small atoms were, and asked us the following question: if you counted up the number of atoms in a typical raindrop, then someone gave you that many grains of sand, how much sand would you have?

A bucket?  A swimming pool full?  A whole beach full?  All of those, it would seem, constitute a crapload of sand grains.  Surely there can't be more atoms in a raindrop than there are sand grains on a typical beach.

But there are.  By several orders of magnitude.  Her answer was that you'd have enough sand to fill a trench a meter deep and a kilometer across, stretching from New York to San Francisco.  (I've never checked her math, but from other similar analogies, it seems pretty spot-on.)

The same happens when I'm considering things that are very large; as much as I've studied astronomy, I never fail to be blown away simply by how enormous the universe is.  In fact, this is why the topic comes up -- a paper in Nature Astronomy last week by astrophysicists Peng Wang and Noam Liebeskind (of the University of Potsdam), Elmo Tempel (of the University of Tartu, Estonia), Xi Kang (of Zhejiang University, and Quan Guo (of Shanghai Astronomical Observatory) has demonstrated that there are filaments spanning entire galactic superclusters, and possibly longer than that.

[Image licensed under the Creative Commons The cosmic web, CC BY-SA 4.0]

The presence of these filaments, which seem to be composed largely of dark matter, comes from their effects on the galaxies they pass near.  As if they were the axle of an enormous whirligig, the filaments cause the galaxies to circle around them, drawn in by the gravitational pull.  The existence of the filaments was demonstrated by the fact that the galaxies on one side exhibit a lower than expected red shift and the ones on the other side a higher than expected red shift, meaning one side is moving away from us and the other side toward us -- just as you'd expect if the galaxies were circling some invisible center of gravity.

As with any groundbreaking discovery, it's opened up as many questions as it's answered.  "It's a major finding,” said study co-author Noam Libeskind, in an interview with Vice.  "It's a pretty big deal that we've discovered angular momentum, or vorticity, on such a huge scale.  I think it will help people understand cosmic flows and how galaxies are moving throughout the cosmic web and through the universe... [and] to understand the important scales for galaxy formation and ultimately, why everything in the universe is spinning and how spin is generated.  That is a really, really hard question to solve.  It's an unsolved question in cosmology."

That was my first reaction; what on earth (or off it, in this case) could generate that kind of angular momentum?  Think of the mass of a typical galaxy, and imaging that you tie that amount of mass at the end of a long rope and try to swing it in circles.

That's the quantity of energy we're talking about, here.  Multiplied by the number of galaxies in the universe.

But the upshot is that the universe on the largest scales seems to have an intrinsic spin, and no one knows why.  All I know is that it makes me feel very, very small.

Of course, I'm way larger than the atoms in a raindrop.  So there's that.  Now that my mind is sufficiently blown, I think I need to go huddle under my blanket for a while, because the universe is sometimes a really overwhelming place to live.

Through a glass, darkly

I was chatting with my younger son a couple of days ago.  He's a professional scientific glassblower, so anything having to do with the properties, chemistry, or uses of glass is going to interest him automatically.  And this was how he ran into the name of Walter John Kilner.

My son asked me if I'd ever heard of him, which I hadn't, and he suggested I look into him as a possible topic for Skeptophilia.  What I found out was pretty interesting -- straddling that gap between "fascinating" and "crazy."

Kilner, who lived from 1847 to 1920, studied medicine, physics, and engineering at Cambridge University, eventually earning a master's degree as well as a doctorate in medicine.  He had a private medical practice as well as being a "medical electrician" -- then a brand-new field -- at St. Thomas Hospital in London.

So the man was certainly not lacking in brains.  But he veered off into an area that is fringe-y at best, and to this day we don't know if what he was seeing was real.

The basic idea is familiar to us today as the "aura," but what most people mean by that -- some sort of spiritual halo around humans (and supposedly, all living things) that conveniently can't be measured by any known technique -- is several shades more woo-woo than what Kilner meant.  He seems to have latched onto the idea of there being a kind of electromagnetic radiation given off by the human body that was outside the range of human vision, and which could potentially be used as a diagnostic tool if a device was developed that allowed us to see it.

In fact, there is invisible radiation coming from our bodies; it's infrared light, which is light that has a longer wavelength than red light.  (Nota bene: it took me some pondering to get past the misunderstanding that infrared and thermal radiation aren't the same thing.  Thermal radiation can be in any region of the spectrum -- think of the red light given off by a hot stove burner.  The wavelength of thermal radiation is dependent upon the temperature of the source.  Infrared, which can be emitted thermally, is defined by having wavelengths longer than that of visible light, regardless of how it's generated.)

More germane to Kilner and his goggles, although the human eye can't detect it, mosquitoes' eyes can (one of the ways they find us in the dark), and it can be sensed by the "loreal pits" of pit vipers that they use for finding prey at night, not to mention the infrared goggles used by the military, which convert long-wavelength infrared light to shorter wavelengths that we can see.  

So there was at least some scientific basis for what he proposed, and remember that this would have been in the late nineteenth century, when the properties of electromagnetic radiation were still largely mysterious.  What Kilner proposed was that since light is altered when it passes through filters of any kind, there might be a filter that could take the electromagnetic radiation from the aura and convert it to visible light.

His approach was to take thin layers of alcohol-soluble dyes, most derived from coal tar, sandwiched between two sheets of clear glass.  He claimed he found one that worked -- a blue dye he called dicyanin -- but according to Kilner, it was difficult to produce, so he started fishing around for a substitute.

Along the way, he convinced a lot of people that his dicyanin filter allowed him to see the human aura, and generated a huge amount of enthusiasm.  People suggested other blue dyes -- cobalt-based ones, and other coal tar derivatives like pinacyanol -- but the results he obtained were equivocal at best.  Nobody was able to produce dicyanin again, or even figure out what its chemical composition was, which certainly made any skeptics raise an eyebrow.  But to the end of his life, Kilner swore that his dicyanin filter allowed him to see clearly an aura around his volunteers' naked bodies, despite an analysis by the British Medical Journal stating bluntly, "Dr. Kilner has failed to convince us that his 'aura' is more real than Macbeth's visionary dagger."

So what, if anything, did Kilner see?  The easiest answer is: we don't know.

The whole thing reminds me of Kirlian photography -- those familiar (and striking) photographs that result from placing a photographic plate on top of a high voltage source, then adding a flat object of some kind.  This produces a coronal discharge, a purely physical effect caused by the voltage creating temporary ionization of the air molecules.  Pretty much anything works; I've seen Kirlian photographs of coins.  But this doesn't stop the woo-woos from claiming that Kirlian photographs are capturing the aura, and giving it all sorts of spiritual and/or esoteric overtones.

In the case of Kilner, though, the effect was never successfully replicated.  This hasn't stopped people from making "Kilner goggles" that you can still buy online, if you've got no better use for your money.  But as far as Kilner himself, he seems to have been entirely sincere -- i.e., not a charlatan or outright liar.  He pretty clearly believed he'd seen something that deserved an explanation.  Whether it was some kind of optical effect produced by his mysterious dicyanin, or a faint blur in the image that he then gave more significance than it deserved, we honestly don't know.  (This is reminiscent of the "canals of Mars," first described by astronomer Giovanni Schiaparelli, which were clearly an artifact of poor telescope quality -- when the optical equipment improved, the Martian canals mysteriously vanished, never to be seen again.)

Another possibility, though, was brought up by my wife; a lot of the dyes and solvents that Kilner used are neurotoxic.  It could be that what he was seeing was a visual disturbance caused by inhaling the fumes from nasty compounds like polycyclic aromatic hydrocarbons, common in the coal tar he was using to prepare his dyes.

The interesting thing is that Kilner completely dismissed the esoteric spin that auras were given during the last decade of his life, primarily by the Theosophists and Spiritualists who were skyrocketing in membership during the first decades of the twentieth century.  Kilner remained to the end a staunch believer in the scientific method, and that anything he'd seen had a purely physical origin that was explainable in terms of the properties of light and electromagnetism.

It's an interesting case.  The fact that in the hundred years since he died, no one's ever been able to replicate his findings, strongly supports the fact that he was simply wrong -- he'd seen something, but it had nothing to do with anything that could be called an aura.  Even so, he's an interesting example of someone who was clearly trying to do things the right way, but his own determination to prove his conjecture blinded him to the obvious conclusion.

Further stressing the truth of Leonardo da Vinci's statement that "We must doubt the certainty of everything that passes through our senses."

A moment of Judeo-Christian silence

Let me start out with a reality check: despite what the Religious Right and the pseudo-pundits on Fox News want you to believe, there is no law against students praying in public school.  Nor is it against the rules for any student in any public school in the United States to have, or read, a Bible.  Nor to cite it (or Jesus) as an influence in their lives in personal essays.  No school has stopped students from reciting the Pledge of Allegiance because it contains the words "under God."  Bible study and Christian fellowship groups are allowed to hold meetings on school property as long as attendance is completely voluntary.

Anyone who claims otherwise is wrong at best, and flat-out lying through their teeth at worst.

What is not legal is mandating prayer in school, or using Christian membership or affirmation as a qualification for... well, anything.  Schools cannot legally force students to follow the precepts of any religion.  The upshot is that public schools are simply not the venue for generating religious adherence, or (for that matter) preventing it.  It is no more teachers' place to alter their students' religious views in either direction than it is for churches to teach their congregations algebra.

As a personal case in point:

  • I responded to questions about my own religious beliefs with "that isn't relevant to the discussion" -- even while we were studying fraught topics like evolution.
  • I had a Bible on the bookshelf in my classroom.  I was given it by a student many years ago, and saw no reason it shouldn't be there.
  • I saw students praying before exams and saying grace before lunch, and no one ever stopped them or had any problem with it.

As a brief aside, there is an explicit conflict in the "under God" part of the Pledge, in my opinion, because if it's recited by students -- which it still is, in public schools across the country -- it pressures non-religious students to affirm something they don't believe it (i.e., to lie).  I find that people who argue against taking out the words "under God" (which, by the bye, were not original to the Pledge but were added in the 1950s) often can't come up with a cogent reason why the words should be recited in a public school where (1) attendance is compulsory, and (2) there are students (and adults) of all different gradations of belief and disbelief.

But of course, that "live and let live" (or, as my mom used to put it, "your rights end where my nose begins") attitude isn't enough for the sanctimonious spokespeople of the Religious Right, who will stop at nothing to inject religion back into public schools.  And not just any religion, of course:


If there was any doubt about this, it should be put to rest by what happened in Florida (of course it was in Florida) last week.  A new law was signed by Governor Ron DeSantis that will mandate a sixty-second "moment of silence" that must be observed in all public schools.  The proponents gave some lip service to a broad-minded sentiment behind this -- that students need to have time to engage in meditative self-reflection -- but the real reason was given away by the bill's sponsor, Representative Randy Fine, who tweeted triumphantly, "Just joined Governor DeSantis to sign my fourth bill of the 2021 Legislative Session, allowing prayer back into schools via a moment of silence for all our schoolchildren.  I won't stop fighting against woke radicals who which [sic] to drive out Judeo-Christian values from every aspect of our lives!"

You'd think that anyone with any sense would recognize that saying this explicitly is just asking for the filing of lawsuits to invalidate the new legislation, but DeSantis, who certainly wouldn't be in contention for the "smartest governor in the United States" award, not only didn't contradict Fine but immediately agreed.  "The idea that you can push God out of every institution and be successful," DeSantis said, "I'm sorry, our Founding Fathers did not believe that."

"Students are free to believe what they want" isn't enough for these people; Fine and DeSantis make it clear that the "moment of silence" bill is just a foot in the door for reinserting prayer -- Christian prayer, of course -- back into public school classrooms.  And call me a "woke radical" if you like, but no compulsory prayer of any kind belongs in publicly funded institutions.

And for fuck's sake, it's not like public school teachers have time to do some kind of subversive anti-religious indoctrination.  I was a teacher for 32 years, and never once did I say, "Okay, kids, we've got an extra twenty minutes today, I will now teach you how to blaspheme!"  I had enough on my hands trying to get high schoolers to understand the Krebs Cycle and Mendel's Laws and the reactions of photosynthesis, I definitely didn't have the space in the curriculum to devote to undermining students' dearly-held religious beliefs.

Nor, might I add, did I have the desire to.  I may be a staunch atheist myself, but I am firmly of the opinion that everyone arrives at their understanding of how the universe works in their own time and fashion, and while I may disagree with someone's worldview, it's not my place to criticize it -- or honestly, even to make a judgment about it at all.

Unless that worldview involves compelling others to alter their own beliefs and actions.  It's all very well to say, "I do this because it's required by my religion;" when you start saying "you have to do this because it's required by my religion," you're going to have a fight on your hands.

Under the ancient skies

I find it fascinating how long humans have been curious about the nature of the universe.  Our drive to understand the world and its workings certainly goes back a very long way.  Some of it can be explained purely pragmatically -- a commonly-cited example is the development of accurate sidereal calendars by the ancient Egyptians to get the timing right for the annual Nile floods, critical not only from a safety standpoint but because figuring out a way to manage all that water was essential for agriculture in what was then a rapidly-growing population.  But it goes far beyond that.  It seems like as far back as we have any kind of records at all, we've wanted to know what makes the cosmos tick.

A particularly fascinating example of this came my way via my friend, the brilliant writer Gil Miller, who seems to have an uncanny knack for finding stuff that (1) I will find really interesting, and (2) I haven't heard about before.  Yesterday he sent me a link from the site New Scientist about an archaeological find in Turkey that -- if the researchers' conclusions are borne out, will provide another example of how early we developed our compulsion to understand what was going on up there in the night skies.

The site is called Yazılıkaya, and it was built by the Hittites 3,200 years ago near their capital city of Ḫattuša.  (The nearest modern town is Boğazkale, in central Turkey.)  It has hundreds of images carved into the rock surfaces, and according to this new study, they represent not only solar, lunar, and sidereal calendars, they are a representation of their concept of the structure of the universe.

The shrine at Yazılıkaya

The current study was the product of a tremendous amount of work.  "There are many connotations with the names of the deities and the arrangements and groups, and so in retrospect it’s pretty easy to figure it out," said Eberhard Zangger, one of the researchers who investigated the site.  "But we worked on it for seven years...  [The Hittites] had a certain image of how creation happened.  They imagined that the world began in chaos, which became organized into three levels: the underworld, and then the earth on which we walk, and then the sky.  The second aspect of Hittite cosmology was a recurrent renewal of life – for instance, day following night, the dark moon turning into a full moon and winter becoming summer.  The calendar-like carvings reflect this cyclical view of nature."

Of course, back then, there was no particularly accurate way to measure stellar and planetary positions, and anything like a telescope was still two millennia in the future.  But even so, they did pretty damn well with what they had access to, especially given how long ago this was.  The Hittites controlled most of what is now modern Turkey from 1,700 to 1,100 B.C.E., at which point attacks from the Phrygians and Assyrians pretty much smashed the power structure and subsumed the culture.

From our modern knowledge of cosmology, the Big Bang and stellar evolution and astrophysics, their conclusions seem pretty rudimentary.  They, like most of the contemporaneous societies, put the whole thing in the hands of gods and sub-gods and so on, giving the whole thing a religious rather than scientific veneer.  "Obviously that makes sense, because that’s exactly what religion does," said archaeologist Efrosyni Boutsikas, of the University of Kent, who was not involved in the current research.  "It addresses universal concerns and the place of the people in the world."  She added that she's not 100% sold on the conclusions of Zangger and his colleagues, but that the site and others near it are deserving of further study.

I'm certainly not qualified to judge the quality of the research nor the legitimacy of the team's conclusions, but I am fascinated with how long we've been trying to figure out how everything works.  As Boutsikas said, religion is a common first-order approximation, and although in many cases it became solidified into a compulsory belief system that then became a hindrance to scientific advancement, it does represent our drive to reach beyond our day-to-day concerns and glimpse the mechanisms controlling not only the movements of things here on Earth, but of those unreachably distant points of light we see gliding through the night skies.  Awe-inspiring, isn't it, to think that our ancestors 3,200 years ago were looking at those ancient skies, and trying to make sense of it all -- just as we're still doing today.

**********************************

In 1924, a young man named Werner Heisenberg spent some time on a treeless island in the North Sea called Helgoland, getting away from distractions so he could try to put together recently-collected (and bizarre) data from the realm of the very small in a way that made sense.

What he came up with overturned just about everything we thought we understood about how the universe works.

Prior to Heisenberg, and his colleagues Erwin Schrödinger and Niels Bohr, most people saw subatomic phenomena as being scaled-down versions of familiar objects; the nucleus like a little hard lump, electrons like planets orbiting the Sun, light like waves in a pond.  Heisenberg found that the reality is far stranger and less intuitive than anyone dreamed, so much so that even Einstein called their theories "spooky action at a distance."  But quantum theory has become one of the most intensively tested models science has ever developed, and thus far it has passed every rigorous experiment with flying colors, providing verifiable measurements to a seemingly arbitrary level of precision.

As bizarre as its conclusions seem, the picture of the submicroscopic world the quantum theory gives us appears to be completely accurate.

In Helgoland: Making Sense of the Quantum Revolution, brilliant physicist and writer Carlo Rovelli describes how these discoveries were made -- and in his usual lucid and articulate style, gives us a view of some of the most groundbreaking discoveries ever made.  If you're curious about quantum physics but a little put off by the complexity, check out Rovelli's book, which sketches out for the layperson the weird and counterintuitive framework that Heisenberg and others discovered.  It's delightfully mind-blowing.

Finding the "cauld grue"

I had a recommendation from a reader to devote one day a week to my other passion besides science and critical thinking -- fiction.  I thought it was an interesting idea, so we'll give a try to Fiction Fridays.  I'm planning some book reviews, excerpts, essays, and so on -- let me know if you like it!

***********************************

Most of my books are about the supernatural, and some of them are intended to be downright terrifying.  Along the way I've been influenced by many superlative writers of scary fiction, so I thought I'd start Fiction Friday with a few recommendations for some of my favorite Tales of the Supernatural.  I'll be curious to see what my readers think -- and to hear what your favorites are.  Always looking for new stories to read...

I have fairly definite opinions about reading material (okay, to be truthful, I have fairly definite opinions about most things, as long-time readers of Skeptophilia know all too well).   To me, a good horror story is one that is evocative, in which there is a subtle touch – the imagination, I find, is far more powerful than the written word in creating frightening imagery.  As Stephen King pointed out in his wonderful analysis of horror fiction Danse Macabre, it's often as scary to leave the door closed and let the readers spend the rest of their lives speculating about what was behind it than it is to actually open the door and reveal the monster (and take the chance they'll say, "Is that all it was?").

This is why gruesome stories really don't do much for me.  A story about a murderer with a chainsaw might disgust me, it might incite me to check to see if my doors are securely locked, but it doesn't give me that thrill of fear up the backbone that is what I'm looking for in a good spooky story, what the Scots call "the cauld grue."  Sheer human perversity doesn't fill the bill; there has to be some sort of supernatural element, to me, for a story to really cross the line into the terrifying.  Reading about homicidal maniacs simply is neither very appealing nor very scary (however scary actually meeting one would be).

All this is rather funny, because I don't actually believe in the supernatural, and I obviously do believe in the existence of homicidal maniacs.  The fact that something that doesn't exist can scare me far worse than something dangerous that does exist is probably just evidence that I'm not as highly evolved in the logic department as I often claim to be.

In any case, if you're curious, here are my top ten choices for the scariest stories of all time.  Let's hear what you think -- if you agree, disagree, or if you were prompted to find and read any of these.  Could make for an interesting discussion!

These are in no particular order, and there are no spoilers -- just a brief idea of what the plot is.

"What Was It?" by FitzJames O'Brien.  A house is haunted by a real, corporeal creature that also happens to be invisible.  And insane.

"The Dunwich Horror" by H. P. Lovecraft.  This is one of the most eerily atmospheric stories I've ever read, about an old man obsessed with recovering ancient lost magical lore, who should have left well enough alone.  Set in the wooded hills of northern Massachusetts, it is serious nightmare fuel, and one of Lovecraft's best.

"The Mirror" by Haruki Murakami, from his collection Blind Willow, Sleeping Woman.  If I had to vote for the single best-crafted short story I've ever read, this would be a strong contender.   A group of friends gets together for an evening of drinking and chatting, and someone notices that the host's apartment has no mirrors, and asks why.  Reluctantly, he explains.  You'll see why he was reluctant...

The Shining by Stephen King.  Combines haunting with the familiar horror fiction trope of "we're all stuck here and can't get away," in absolutely masterful fashion.  Skip the movie and read the book.  You'll never look at a bathtub, or an old-fashioned elevator, or a long hotel hallway the same way again.

"Oh, Whistle and I'll Come To You, My Lad" by M. R. James.  A regrettably little-known story which is one of the flat-out scariest things I've ever read.  A British tourist finds an antique whistle half-buried in the sand on the beach, and blows it.  He shouldn't have.

"The Monkey's Paw" by W. W. Jacobs.  Embodies the old saying "Be careful what you wish for, you may get it," and is the classic example of -- literally, in this case -- not opening the door.

"Afterward" by Edith Wharton.  If this story doesn't scare the absolute shit out of you, you're made of stone.  A story about... a retroactive haunting?

"The Lottery" by Shirley Jackson.  Not a supernatural thriller, as per my original description (so sue me).  But still a classic of horror fiction.

"August Heat" by William Fryer Harvey.  What if you happened upon a stranger, a maker of marble monuments, and he was making a headstone -- with your name, and today's date, on it?

"Ligeia" by Edgar Allan Poe.  One of the earliest stories of possession.

So, those are my top ten.  Agree?  Disagree?  Any additional that you would recommend?  What stories have chilled your blood, that would be appropriate to sit in front of the fire with, late at night, when no one is awake in the house but you?

In 1924, a young man named Werner Heisenberg spent some time on a treeless island in the North Sea called Helgoland, getting away from distractions so he could try to put together recently-collected (and bizarre) data from the realm of the very small in a way that made sense.

What he came up with overturned just about everything we thought we understood about how the universe works.

Prior to Heisenberg, and his colleagues Erwin Schrödinger and Niels Bohr, most people saw subatomic phenomena as being scaled-down versions of familiar objects; the nucleus like a little hard lump, electrons like planets orbiting the Sun, light like waves in a pond.  Heisenberg found that the reality is far stranger and less intuitive than anyone dreamed, so much so that even Einstein called their theories "spooky action at a distance."  But quantum theory has become one of the most intensively tested models science has ever developed, and thus far it has passed every rigorous experiment with flying colors, providing verifiable measurements to a seemingly arbitrary level of precision.

As bizarre as its conclusions seem, the picture of the submicroscopic world the quantum theory gives us appears to be completely accurate.

In Helgoland: Making Sense of the Quantum Revolution, brilliant physicist and writer Carlo Rovelli describes how these discoveries were made -- and in his usual lucid and articulate style, gives us a view of some of the most groundbreaking discoveries ever made.  If you're curious about quantum physics but a little put off by the complexity, check out Rovelli's book, which sketches out for the layperson the weird and counterintuitive framework that Heisenberg and others discovered.  It's delightfully mind-blowing.
