But how? Part 10: Uncertainty

Walkabout podcast – But how? Part 10

It’s admittedly been a while since the last ‘But how?‘ post, and the reason is, I’ve been having trouble finding further topics that fit the goal (which is demonstrating how a secular worldview answers more than what religion is often claimed to do.) So there’s a modicum of irony in this one, in that the question I’m tackling is about unanswered questions. Since I can’t think of a way to phrase this in the form of a question that covers all the bases (no Jeopardy! champion here,) let’s just jump into the topic of uncertainty.

I want to get the fatuous example out of the way first, because it disturbs me how often I hear it and I’d rather deal with ideas that demonstrate the possession of brain cells. There really is an argument that “science” changes all the time, but scripture is perpetual and unchanging, and this is made as if it’s a point in scripture’s favor. Now, seriously, who gives a rat’s ass about something unchanging if it’s perpetually wrong? We all know people like that, and they’re assholes – I personally would far rather hang with someone who can learn. Hidden within this is a subtler, but much more important fact: science is a process, not a religion unto itself, and a process intended to be utilized by us imperfect humans. Its ability to find and accept corrections is most of what makes it so useful. There is an interesting avenue of psychological research into why someone would possibly place more value on permanence than accuracy, but that’s for someone else to pursue.

One of the primary assets of religion, according to the manufacturer, is how it provides answers. Faced with the uncertainty of life’s purpose, or the path one should be taking, or how to get children to eat their vegetables, religion is invariably brought up. That religion itself may actually be a manifestation of the desire for answers is something examined in part four. What can be found most often though, if one examines these religious answers, isn’t practical solutions or explanations, but emotional supplication – assurances that we’re special, or that life really is fair, or that misfortune has a useful purpose. Such answers have a modicum of value it would seem, especially if the alleviation of superficial anxiety is all that was needed.

Science and naturalism and secularism, in contrast, present poor substitutions for emotional surety. There appears to be no purpose to life, and no assurance that it’s fair. Humans aren’t special, at least in the way we’ve been told, and evolved from filthy brutish beasts, except that we don’t even have a distinct line to follow and more bits keep getting added or changed. Morality is not a set of rules (especially ones that place us firmly on the preferred side) but an amorphous concept influenced by culture and debate. And death really is the end, without appeal – in whatever sense of the word you prefer.

Actually, that last one is just the opposite, an example of distinct surety negating any idea of judgment or consequence, isn’t it? And this highlights the same thing mentioned earlier: answers that are only acceptable if they’re what we want to hear. Science and naturalism and secularism have very distinct answers to all of these, and many more things besides; some of the questions are only present because of gross misunderstanding or rigid perspective (often created by religious teachings, imagine that,) while some of the uncertainties are selected and highlighted precisely because they strengthen the religious worldview. As an example of the latter, we can see that “missing links” and unclear lineages in the human evolutionary tree are seized upon repeatedly, while ignoring the millions of data bits that demonstrate the presence of evolution in the first place, not to mention the gross mismatch between the fossil record we can find everywhere and the superficial creation stories from scripture. We do not need to have a complete human lineage to infer that there is one, any more that we need to have seen someone break the window to determine what happened. If we find broken glass inside the house, and look around and indeed find the suspected baseball, this supports the theory of how it occurred – and this is exactly what we continually find with the theory of evolution.

There may be no overriding purpose to life, but this does not mean individuals cannot possess their own – the freedom to do so, in fact, is preferred much more than predestination, and even what ‘free will’ was invented to allow. Morality isn’t about rules to be dictated, but a goal to be pursued, and requires knowing what the goal is (choosing benefit over detriment to the greatest degree, in case I actually have to inform anyone) – coupled with realizing when actions are motivated by other emotions; psychology and evolution have helped us to understand what factors impinge on this and why. And there really isn’t any reason to differentiate us from “beasts,” nor a reason to be worried about this; humans are actually much more self-destructive than nearly all other species anyway, so there’s no high horse to sneer down from.

All of these highlight a particular idea: that uncertainty is a human trait, prompting us to search for answers – but some answers are explanatory and fit together in the big tapestry of naturalistic physics, while others are just intended to make us feel better. Which means some people are driven solely by their self-indulgence, while others seeks answers because they answer the question.

We can see this in sharp relief when we examine the religious answers with the same eye as the scientific ones. Despite a few thousand years of any (unchanging, mind you) religion, we still seem to have people seeking answers. The purpose of life is different for anyone you ask, often hiding behind the skirts of “something bigger than we can fathom” – so the answer actually is, “We don’t know”? Yeah, fabulous. Even religious moral guidance doesn’t present any end goals or decent structure, but lists of proscribed actions often overlaid with stroking the ego of a perfect being (producing a peculiar definition of “perfect” in the process.) Most of the scriptural accounts portray incredibly ludicrous events and motivations, intertwined with myriad ways of justifying the bigotry and classism that we actually want morality to get us away from. Even Sophisticated Theologians™ cannot agree on what ‘The Fall’ or ‘The Resurrection’ actually accomplished, and chapters within scripture routinely contradict themselves, or portray wildly variable goals and personalities for any god. It’s frankly astounding how anyone can derive something approaching answers from this, and it becomes far worse when we capriciously consider all religions and try to objectively decide on which is most accurate.

This rarely happens, of course, because the ‘certainty’ of religion is mostly repetition, and placing a ridiculous positive value on faith, defined as certainty without evidence. The structure of too many religions is to reinforce a mode of thinking, avoiding independent thought, actively discouraging the unwanted penetrating questions, and demonizing (a ha ha) any opposition. There have been numerous psychological studies over how people tend to follow the crowd and reflect what popular opinion is, rather than trust their own judgment, and naturally this is exploited as well – does anyone believe there’s really a point to weekly religious meetings over a finite (and unchanging, let’s not forget that) set of scripture?

All of that comprises the top reason given among those who have abandoned religion: it didn’t make sense, didn’t try, and alienated (sometimes quite vociferously) anyone who desired real answers. Religion does not alleviate uncertainty at all, it just attempts to obscure it and assert circumstances that don’t connect with anything that we can rely on, while explaining nothing. It’s one thing to find a new question underneath any particular answer; this is, indeed, why science goes on. It’s yet another to receive a statement that doesn’t actually answer any question and yet raises more of its own, where the requests for clarification are met with vague appeals or outright hostility, making uncertainty seem shameful and the quest for knowledge to be wrong. If you ever wanted to know what brainwashing looks like, just pay attention to the religious response to any scientific finding that proves scripture inaccurate. In fact, the stunning amount of censorship from religious folk demonstrates very forcefully that religion is not about seeking or providing answers.

It’s abundantly obvious that we are a species prone to uncertainty – and this is no bad thing, because it motivates us to try and eradicate it, producing curiosity and interest and the drive to learn more about our world. Science embraces this, encouraging investigation and promoting methods that reduce uncertainty as much as possible, at the same time presenting the collective efforts of millions to anyone who really wants to know more. But we don’t even need to go that far, as we address our own uncertainties by finding out what’s wrong with the car, going to the doctor, rooting through a box of old items, or simply reading to the end of a murder mystery. Religion, on the other hand, presents responses which explain little and lead nowhere, not even giving a likely indication of what we can expect. Its certainty doesn’t come from clarification or prediction, only from assertion and repetition, often in the face of contrary evidence – this attempts to change the definition of “certainty” to something like “blind acceptance.” For many, that’s just not enough – they don’t want to have faith, they want to have confidence. And we can thank this lack of blind acceptance for the vast majority of advancements we’ve made as a species.

Sleep tight

If you’re arachnophobic, this post isn’t for you, unless you’re determined to get over it or just realize that it’s only pics on your monitor. I’ve done my part in warning you and am now absolved of all legal liability and suchlike.

A few weeks back while hunting bugs at night for The Girlfriend’s Younger Sprog (long story,) I caught a flash of reflected light from the headlamp, in a weed thicket. I shifted back and forth, unable to make out the source (which I was sure was a spider,) and surmised that the culprit was likely hiding behind some dead leaves – until I realized the culprit was the dead leaves, or what I’d taken for such anyway. Coaxing her out was a little tricky, but she was remarkably patient for all the shots I took.
Honkin1
This is a variety of fishing spider, genus Dolomedes, which remains unidentified because several species have very subtle differentiations that I did not capture in images. And yes, that’s an egg sac she’s clutching possessively. The various wolf spiders keep theirs attached to their spinnerets and are able to hold them off the ground if necessary that way, but the fishing spiders (from my experience) seem to also hold the sacs with their chelicerae – I’m pretty sure it’s also affixed to her abdomen, tucked down in an atypical angle. She hadn’t appeared to be going anywhere when I found her, and even my messing about didn’t produce more than some shy edging away, not so much that I wasn’t able to go in ridiculously close.
Honkin2
Fishing spiders, or at least some of the species, are not always found near water sources, and a few of my encounters have been quite far from them. Sometimes, they find whatever’s handy. My model here stayed put while I went inside to collect my calipers for some blog data, allowing me to give a better idea of scale:
Honkin3
That’s a leg spread of 8cm (3+ inches,) which is large enough to give me the heebie-jeebies to some extent – even knowing her fangs were full of future fry, when she started up the branch towards my hand I was unable to let her complete that journey. Some day, some day. But as a concession, I went with another image to show scale:
Honkin4
[As I was previewing the post so far, a teeny spider about the size of this >. strolled down the monitor, just for a giggle.]

Yes, I go all Nature Boy barefoot in the summer, partially in self-defense – shoes make my feet ridiculously hot, and even in winter I’m often in ventilated sneakers. It does lead to the occasional issue, as I’ll relate a little later on, but the spider was unconcerned – no sense of smell, I believe.

Tonight as I type this, I had been outside checking on conditions for the Perseids shower (which are rotten – too much cloud cover,) and spotted a familiar blue-green light from the grass. This time around it was a much smaller wolf spider, leg spread maybe 2cm, but she was ferrying her young around on her back, as they are wont to do. I’ve been wanting to try an experiment but haven’t found a suitable subject until now, so I went in and fetched the ringflash for that direct lighting effect, and did indeed get what I was after:
Reflections
The raindrops aren’t helping the issue any – it would have been more obvious without them – but those blue points are reflections from the eyes of the young (and one big one from the momma.) There aren’t many, because the spiderlings keep their heads inwards for protection, and of course the angle has to be right. The next goal is to separate one or two from the mother and photograph them independently, nice and close.

To offset things a tad, I’ll close with a few much cuter images, for most people anyway. The previous night, I found a variety of sphinx moth hanging out in the rosemary, and tried the ringflash with that too, with excellent results:
Sphinx2
At some point, I may be back to explain this red-eye effect, common to many species of moth, but for now just know that it’s much more brilliant than seen here, reflecting brightly even from a few meters away.

The same storm that I chased in this post may have grounded this next moth, an Antheraea polyphemus, since I found it sitting on the ground the next day.
BigMoth1
Those spots on the wings really are transparent, to what end I cannot say – perhaps it is the Lepidoptera equivalent of lingerie (yes, this is a female, as indicated by the antennae – the male’s are much more feathery.) This is one of the species of moth – the pale green luna is another – that have no mouthparts in the winged adult phase, since they do not feed as adults. This stage is devoted to procreation only, and lasts but a few days.

I had no problem letting this species crawl across my hand, which just goes to show that you can’t judge on appearances – the spider likely would have done absolutely nothing, but this dainty lady defecated on my fingers. And people think insects can’t communicate…

Huff & Puff (BIAB)

BIAB is short for, “Because it’s a blog” – it means this post isn’t thematic or relevant or anything, I just felt like it.

Just A Band is a band (surprise!) from Kenya, and I can’t tell you much more than that, so I recommend you flex your intertapestry muscles if you want to know more about them. Their own description, from that link (which you should definitely check out, if only for the bio) reads,

A Kenyan somewhat-experimental, DIY, geeky boy band who are taking it one day at a time.

I suspect this means it’s not typical Kenyan music, if there can even be said to be such a thing – what would typical American music be? I’m scared to hear anyone’s opinion on that, to be honest…

The video I’ve chosen here, for the song “Huff & Puff” from the album 82, wasn’t the first I came across, but I’m saving that one for another post because it has a little trivia attached. This one, however, has its own mix of delightful visuals, R&B, Hip Hop, and Techno, and since I’m not a huge music buff (meaning I’ve never bothered to learn all the different categories or genres that some people concern themselves with) there may be other things in there as well, or I may be entirely mistaken. Perhaps it’s Neo-Classical Funk Disco. I find it quite catchy, and if you don’t, well, there’s no help for you.

The sneaky bit is that they freely mix languages within the lyrics, mid-sentence even, with enough English that you think you can follow along and then switching to Swahili (or something) to make you believe you’re not listening closely enough. I’m also pretty sure the first half of the video was done in one shot.

You can find the lyrics here if you want to follow along. And no, that’s not Will Smith, but it could be…

Oh, the humanities!

Jerry Coyne and crew have been having a grand old time tearing this debate apart (1st post, 2nd post), but there’s just something I wanted to add. And I can’t really call it a debate, I just haven’t found a better word: it’s basically a few philosophers championing the humanities by tilting at the windmill they call “scientism,” and Steven Pinker crassly injecting some intelligence into the affair. The most striking thing to occur to me is that, if those who have spent their lives studying the humanities are stupid enough to pass judgment on something they can’t understand even superficially, perhaps it really is time to do away with the humanities…

“Scientism” is a curious term, obviously used as a curse most often, but even at the best of times it’s defined without much understanding. Essentially it’s the ideology that everything can be understood through empirical means, gaining knowledge by analyzing data and “reducing” it all down to the physical laws. It really doesn’t take much to see why this might actually be a good idea, for two very solid reasons: the first, that we are physical beings who interact and perceive our entire existence through physical senses; and the second, that all too often when we’ve relied on the spiritual, philosophical, intuitive, emotional, or even logical conclusions produced solely within our own heads, we’ve been fantastically wrong – and these errors have most often been demonstrated by empirical means. In other words, while abstract thought might be a great way to start the investigations into our world, it needs to be backed up with something solid to prove it, because it’s not dependable enough to provide accuracy on its own.

What’s funny about this is how few people actually speak in favor of scientism, or even consider it a valid concept. Science isn’t ruled by any ideology and often proceeds without any at all, most often just driven by curiosity and the (oh so heinous) idea that starting from solid data is a good move. It would appear, however, that a few humanities professors find this to be in extreme bad taste, decrying the intrusion of science into their fields and the ultimate destruction of art, music, literature, philosophy, and degrees that many graduates regret having wasted their time on when they see how rarely the job market has a place for them. According to these professors, scientism is poised to destroy the magic, the mystery, the awe, and the passion that makes the humanities what they are. Even worse (and this really is an argument still put forth, hard as it may be to believe,) we have science to blame for all the ills of the world today.

This isn’t the best argument to put in front of a guy who’s published a book explaining how our social standards are higher, and strife and violence lower, than at any previous point in our history. But even without that, it’s a stupid argument. Understanding why we get any particular feelings from art or literature doesn’t make them go away – and if it does, one must ask just what exactly was so magical about them in the first place. The fear of the humanities professors is exactly the same as that of the theologians: that their realm can be dismissed by science pulling aside the curtain of self deception. The magic, awe, and passion are all emotional reactions. There’s nothing wrong with that, but if they vanish when examined critically, one must wonder what their purpose or value might be.

One must also wonder what can be found when the selectivity is taken away – when one compares the passion of the Mozart enthusiast against the passion of the religious martyr, the transports of the Joyce scholar against the righteousness of the rebel mercenary. These are also emotions, producing more noticeable behavior than the art enthusiast, just not as socially acceptable; considering only the good side is biased, and in fact not worthy of a college professor in any way. Moreover, this ties in surprisingly well with the idiotic argument of how science is responsible for the ills of the world, since even a child can see that it isn’t technology, but how someone is motivated to use it – this is exactly what those in the humanities should be studying and informing us about, rather than avoiding the subject and attempting instead to find a scapegoat by creating a new epithet. The bare fact that there is a significant cultural emphasis on the “bad things that science has done” is direct evidence that those in the humanities are not only failing to make useful contributions, they’re complicit in actively skewing our views of the world. If you question that as a broad assumption, tell me: who else is going to come up with an argument of that nature?

It wasn’t really my intention to demonstrate how feeble the humanities are, but there comes yet another aspect that isn’t helping any. While it’s certainly fine to receive a strong emotional response to a piece of music, there remains no small number of people who then ask, “why?” The curiosity, the passion to find out just what is behind such reactions are also emotions – moreover, ones we can thank for the millions of advances that comprise the collective noun of science in the first place. Science, despite the portrayals of these outspoken philosophers, isn’t emotionless at all, and no one who has ever spent any time in the company of scientists could rationally make that argument – it’s rather pathetic that anyone with even a brief education could think that scientists somehow depart from all the qualities that every other human has. Yet it is also emotions that can lead us astray, clouding our judgment with ego or making us believe in things without evidence – and this is exactly what the scientific method was adopted to combat. It’s ground floor, first-day-of-class knowledge, yet somehow those who have never grasped this feel obligated to render their ruling upon it, as if they have something to contribute.

Pinker missed an opportunity to wield a little Richard Feynman or Carl Sagan, trashing the argument that science takes away the passion and making those that promote it look remarkably ignorant. He also missed a very basic lesson: science is simply a methodical process of learning, not a religion; it does not impose rules on its disciples. The only rules found therein are the rules of the universe, discovered where they lie. Even worse, and this argument is heard constantly, there isn’t any place where science “doesn’t belong” – if we’re curious about something and want to use the best method to understand it that we’ve ever stumbled across in human history, then why would we not use science? In what manner is there some dividing line, some rule, that makes science off limits, and who’s responsible for creating it? If you mutter, “The people who have something to lose,” then I’m in agreement with you.

Those who have put too much faith in philosophy wield the term “reductionism” as another curse, implying that science/scientism works to reduce everything to simplistic ideas (which Pinker does touch on.) However, if such things really can be explained in terms of the molecular or atomic level – if our minds, for instance, can be found to work solely by exchange of chemical energy – then this is not reduction at all, but discovery, and fascinating in and of itself. That is, unless you possess some view that the mind is magic (dualistic/transcendental/immortal/whatever) in some way, in which case you might be disappointed and more than a little frustrated. Such a reaction isn’t either scientific or rational, though, it’s emotional, and not in a good way – petulant, juvenile, self-absorbed, pick any three. The biggest point in all of this, however, is that science only deals with what is, and if we can sense it, there’s no reason why it cannot be quantified for science. If it cannot be quantified, what the hell are we sensing? Wouldn’t the humanities actually be interested in this? You’d think so, if you accepted the goals as stated.

With funding for the humanities getting slashed in many universities, it’s easy to speculate that those who specialize in it are worried about its future – perhaps this is the motivation behind such infantile accusations, perhaps not. But even so, attempting to defend the humanities by denigrating the empirical fields that are producing results every day is a tactic we should only be seeing from reality TV, not from any reputable professor. There are two kinds of competition: improving oneself to be better than others, and tearing down others so one looks better in comparison. If those in the humanities are finding themselves in trouble, maybe they can consider the first option and step up their game. Judging from these ridiculous arguments, there’s plenty of room to grow.

It’s a jungle out there

AmbushProfile
A few days back, I began finding a solitary jagged ambush bug nymph (genus Phymata) on the dog fennel plants. I was pleased, because there’s something about these little predators that’s appealing, and not just to me; The Girlfriend likes them too, solely based on their appearance. I don’t find many of them – my last round of decent photos came two years ago – and a very large adult that I spotted this spring vanished before I could get the lens on it. This one was brilliant white, surprisingly, since they usually rely on camouflage and its chosen eyrie was nothing but rich green threadlike leaves. I’ve had no trouble finding it just about every time I look because of this, despite the fact that it’s less than 5mm in body length.

Earlier this afternoon, I noticed that my friend was sporting some new colors. I’d been pretty certain that there was yellow visible a few days ago, but now a lovely teal hue was also developing on the legs and forebody – still not very effective camouflage, arguably even worse, but rather fetching anyway, so that’s all right.

Chambush
The lack of obscuring color or shape seems not to be hindering it much, however, as I returned later in the evening and found it in possession of a sharpshooter, probably a Graphocephala versuta.

PaleAmbush1
Last year the dog fennel plants had hosted both aphids and lady beetles in vast quantities, but this year the leafhoppers have taken their place (vagaries of season and reproduction I guess,) so the ambush bug has no shortage of available food. And since it hadn’t moved at all from where I’d seen it hours before, it wasn’t like there was a lot of energy expended in obtaining this meal; the sharpshooter had likely just blundered into the Ambush Zone [dramatic music.] Maybe one day I’ll get comfortable and stake out the area to see if I can at least watch a capture, if not get a sequence of images – and I say that knowing that a) I’m liable to need a lot more patience than I actually possess, since I doubt this happens more than once, twice a day, and b) dog fennel plants are not known for their stability, these being three meters tall and waving in the slightest of breezes, which naturally makes macro photography fall somewhere between “demanding” and “fuck this I’m going to become an air traffic controller.” If I were making more money from it I’d probably be a lot more inclined to put in the effort – so if you’d like to see it, get in touch and we’ll talk.

PaleAmbush2
One might be inclined to think that, given the predatory nature and purposeful forelegs, ambush bugs and praying mantids are closely related, but this isn’t the case – they’re actually pretty distant as far as arthropods go, in completely different orders, akin to the difference between humans (order Primates) and otters (order Carnivora,) further separated than humans and lemurs (also Primates.) Ambush bugs are Hemipterans, or ‘True Bugs,’ which means largely that they have sucking mouthparts, and like assassin bugs they drain their prey through their own personal straw, while the mantids crassly and messily dismember their meals like barbarians – but at least they don’t litter the ground with the empties like the Hemipterans. Here’s a nearly full-resolution crop of the same image above, for a better look at the forelegs and proboscis. The black line enhancing the serrations is interesting, but from other images I can say it’s misleading, since these are not sawblades slicing their prey, but merely teeth to maintain a good grip – the contact surface on the distal segment, the one closest to us, is broad like pliers.

AmbushDetail
AmbushScale3I close with a scale shot, more or less since I didn’t want to disturb my model – I just grabbed some identical fennel leaves nearby, which is a lot more illustrative than providing the body dimensions. Hopefully you get the idea that it’s easy to blow past one of these unless you’re paying close attention, and of course it’s significantly harder when the camouflage has kicked in. Arthropod photography often requires close examination of likely habitats, but the nice bit is, almost anything is a likely habitat for something, and you can pursue a wide variety of subjects in your own yard. Just be aware that neighbors walking their dog past at night might find the camera strobe going off to be curious, if not outright startling ;-).

Recognizing pseudoscience

One would think that recognizing pseudoscience is an easy thing, almost intuitive – and, to be honest, it is, provided the right measuring stick is used. But there’s simple, and then there’s simple, you know?

First off, we can get some other bits out of the way first. There’s no reason to get all pedantic over a firm definition of pseudoscience, but can we count such things as false advertising claims? Evidence consisting of folklore and anecdotes? The ‘sole positive’ effect (“I’ve had experience with that once before”)? Sure, if you want, but these seem more to fall under the big umbrella of critical thinking than really anything to do with science – you can apply these to buying a car or choosing a restaurant.

The simplest way is with knowing (as too few people do) that science strives to rule out the false positive, to determine that some effect is not caused by something else entirely. Much more than the positive results, the elimination of alternatives is what gives science its strength – think of it as an Olympics of knowledge, with no Silver or Bronze. Though the new discovery gets the attention, it isn’t even considered a new discovery until it has surmounted the competition and the alternatives – something that popular media perpetually, and inexcusably, misunderstands. In fact, this produces a handy little guideline on its own: whenever any researcher holds a press conference rather than having their paper published in peer-review journals, it’s safe to completely ignore their announcements. Dodging the review process is only useful for those who know their ideas won’t survive it.

There’s another guide as well. Science operates within the tent of established knowledge – physical laws, known properties, demonstrable reactions. This isn’t to say in the least that new properties cannot be discovered, but if they are claimed to contradict something that researchers the world over have been using successfully for decades, it’s fairly obvious that the evidence for such a new property has to be documented and overwhelming – and explain why we have the decades of results that we do. Pseudoscience, on the other hand, often relies on circumventing known properties, proposing new theories with astounding ramifications, while demonstrating no real support for such conclusions – usually, this remains to be found, once everyone can “get past the dogma of accepted science.” Aside from the obvious logic failure with proposing whole new physics sans evidence, this treats science as if it’s a rulebook rather than a process, a mistake made repeatedly – it’s easy to find those who somehow think physical laws and properties are like social laws, based on the pronouncements of authority figures, rather than physical traits that exist in the universe. There is no penalty for breaking the law of gravity, since no one will ever do it.

[Yes, I feel completely confident in making that statement; no one will stop gravity from working, and it’s not going anywhere. The best we might accomplish is to counteract its effect in limited ways, but as a property that holds galaxies together and bends light, we’re not going to find a little switch for it someplace.]

That phrase above about the “dogma” of science (which is able to be found far too often) is evidence of another, more subtle indication of pseudoscience: the emotional appeal. Any time that you hear attempts to manipulate emotions, to disparage accepted knowledge, to defend personal experience, or to compare past mistakes, feel free to save your time and move onward. But if you’re really into being objective, challenge the emotional appeals for what they are and redirect the attention back to solid evidence. Have there been mistakes within science before? Yes, of course – discovered by science itself, as I’m fond of pointing out, and not by psychics or garage inventors or shamans. There have been mistakes in the world of pseudoscience, too, but never self-corrected, imagine that (and I’ll leave calculating the percentages of each as a comparative exercise.) Does someone swear by their experience? Bully for them – humans are fallible, which is blindingly obvious while simultaneously forgotten constantly, and are also stubborn, fatuous, biased, and emotional. Heard a stupid political argument lately? Good – it’s the exact same people assuring you that copper bracelets cure arthritis. Our scientific method exists, in part, because of exactly these traits.

Selectivity is another clue. If you’ve found someone who uses quantum mechanics to explain their pet theory while claiming that science refuses to recognize this effect, you’ve got a winner (or loser, to be more accurate.) When you’re listening to someone warning of the harmful effects of gluten or high-fructose corn syrup, challenge them to tell you how they obtained these indisputable results that nevertheless are being suppressed. Pseudoscience has its poster children, and they are the lone heroes crusading from grass-roots organizations that, somehow, never have any research labs at their disposal. The very same scientists that supposedly provided their rock-solid evidence are the same ones under gag orders from big corporations, or dancing to the tune of the totalitarian government. Have fun with such people, and inform them that if conditions truly were as they say, they would never know what was actually harmful to them. Meanwhile, hidden within all of that is a peculiar concept, of people who place value on science and want to use its dependability and reputation, while ignoring its findings to create their own favorite conclusions. This is a favorite tactic of creationists, who pick and choose the bits they like and openly dismiss the rest, as if results are subject to personal vote.

But even all of this is needless fooling around, because there’s one simple facet that science utilizes constantly, and pseudoscience perpetually avoids. When any potential effect is suggested – for instance, vaccines causing autism – science collects data first to produce a starting point, something dependable, and necessary for any research. Pseudoscience never confirms its data, instead relying on anecdote and suppositions about how prevalent such a thing might be, and even why the real data cannot be produced. Pseudoscience adores excuses, from aliens having stealth technology (explaining why the visual sighting provoked no radar evidence) to negative energy counteracting the telekinetic powers (which makes skepticism far stronger than any psychic – bow before me, you little shits.) Pseudoscience will never, ever deal with the obvious consequences of its theories, like autism rates that should be lower in countries without vaccination programs, or cancer rates that should have surged commensurate with cell phone usage. And contra-evidence is always dismissed, often in the most convoluted ways.

If you’re seeing a pattern of confirmation bias from all this, you’re right – pseudoscience is emotionally based, providing something that the proponent wants to believe, and requires very subjective rules to maintain. Thus, the issue isn’t with knowing how to spot pseudoscience as such, it’s with wanting to spot pseudoscience (or the desperate attempts not to.) While many people feel that operating on the best information and making well-informed decisions is a pretty useful approach (you will excuse the wry understatement,) there are too many others who place personal affirmation and indulgence well above objectivity, finding elaborate ways to rationalize their choices in the face of weak evidence and flawed theories. It’s almost astounding when one thinks about it, because there’s little if any benefit from following pseudoscience, save for petty emotional supplication (that often has to be maintained against any and all critical examination, much less denigration from others,) while the hazards of following pseudoscience extend from loss of significant amounts of money to extensive health issues affecting entire populations. Despite the protests invariably heard whenever pseudoscience is challenged, it is not a “personal choice” in any way – not if you’ve just heard about it. Whole industries devoted to reiki and aromatherapy do not exist to provide a choice, but to influence as many people as will blindingly accept it, using bastardized “research” and misleading or outright false claims to promote some appearance of legitimacy – we can thank exactly such efforts for the rallying cry of “science doesn’t know everything,” (which, by some gross misunderstanding of how logic works, is supposed to provide support for whatever claim someone happens to like in its place.)

It might be easier to ignore such things, thinking that people are going to believe whatever they like and there’s not much we can do to prevent it. But does this make us any different, or are we also rationalizing our choices to avoid confrontation? While it may seem that addressing pseudoscience is just a clash of personalities unless we pursue a greater audience, the effect of such beliefs is pernicious and far-reaching – does it sound better to weather a bit of confrontation to save even one child from dying of a treatable medical condition because their parents bought the bullshit? Worrying about our own convenience and comfort seems petty then, and it is – we tend to think in immediate terms and not the long run. But just sowing a seed of doubt is a start, and even one voice in opposition is far better than the implied consent of silence.

Frustrations, part 12

NotEvenThunderAs several separate thunderstorm cells moved through tonight, I was watching the inordinate amount of electrical activity lighting up the sky like a disco strobe, and figured I should be doing something about it. I haven’t pursued much lightning photography in my current location because it’s remarkably difficult to find a good setting. This area of central NC is loaded with trees, and electrical storms tend to stay close to the horizon, so wide open spaces are much better, preferably with some kind of foreground interest (lakes, lone trees, abandoned houses, mad scientist’s lairs.) Even though I’ve actively scouted for such things, I haven’t found many.

This time around I elected to use a road, and drove out to a nearby connecting spur with a train bridge. Enough traffic to get some vehicle lights, but not too much to crowd up in long exposures while waiting for a decent bolt. The flaw in this plan was not facing quite the right way, and getting only residual light without visible discharges. I wasn’t ready to give up yet, so I packed up and tried to find a place that would let me see more of the cells. It took a bit of driving, but I located an open field facing the right way and bordered by a wandering treeline

Now, a few words about lightning photography. Like meteor showers, what is almost guaranteed to happen is that you will see a brilliant display, either just outside of the camera’s field of view, or while you are looking through the view finder framing the image right before actually tripping the shutter. This did of course happen tonight as I realized there was more activity off to the right and re-aimed the camera, seeing but not capturing a lovely strike right in a gap in the treeline.

Something that can be nice to capture is the shape and texture of the clouds lit up by lightning, especially from within, but this is actually a different exposure than for lightning itself. In this case, I was working with mostly hidden discharges, so getting anything at all in an image required f5.6 at ISO 200, and exposures longer than 30 seconds with lots of visible activity therein. This is a little tricky; with the right light, you get lovely cloud detail, but this often takes multiple flashes to achieve, and if the front or cell is moving fast but there’s too much time between discharges, you overlap faint cloud exposures when the clouds have moved, producing more of a hazy effect than getting detail. I usually advise no more than three bright flashes before you close the shutter and take another photo.

Then there’s the more immediate problem of getting a brilliant bolt in the frame, exactly as desired, when the exposure is set for clouds:

Blinded
If you look close just to the right of the white area, you can barely see the branches off of the main bolt, which is hidden within that glare. But don’t the clouds look nice?

This happened three times, partially because I don’t trust the LCD to tell me what I captured and ignored the washout, thinking it would resolve better on a proper monitor. In my defense, I was working with distant, dim bolts, hidden flashes, and the occasional piercing strike like this one that was bright enough to make me blink and left an after-image on my retina. And yes, I did change settings to try and capture such bright blasts, which is when they stopped coming and all of those subsequent exposures have virtually nothing in them at all. This is storm-chasing; you can’t make it work for you, you can only try to plan and hope luck favors you.

And sometimes, it does.

WorthTheTrip
I’m especially pleased with the glow from the cloud right at the top of the bolt – never captured that before. Now all I have to do is get activity like this tied in to a nice foreground, especially one I can get to quickly when I see the right conditions rolling in.

All the answers

So, let’s look at this in detail. We all know jesus could walk on water, but could he sleep on water? Could he even swim? If he dove off the dock, would he break his neck?

Maybe the effect was limited to his feet, in which case he’d have to be careful of his balance. Could he walk on rough water? Would he orient to the surface, pivoting around on the crest of an incoming wave? Stand upside down inside one of those monster curlers off Tahiti? If the bit he was standing on broke off, would he fly off with it? How small could the body of water be and support him? Could he walk on foam or mist? Would he be trapped by fog?

Again, if he dove off the dock, would he be brought up short as soon as his feet hit the surface, dislocating his ankles?

Perhaps it was conscious, and could be turned off at will. Could he then sink in slowly and halt halfway? Bob up and down? Could he climb out, like walking up stairs? Or maybe it was simply an on/off thing, and if he switched off he’d simply drop in like anyone else. Would switching it back on after that do anything? If he went very deep, then switched on, how fast would he surface? Would we see a breaching jesus explode out of the water? What if he screwed up the balance thing and came hurtling out feet first with a lot of water up his nose? Could water go up his nose? Did he have to make a conscious effort to drink a glass of water? Maybe that’s why he could turn water into wine.

I lie awake at night thinking about these things.

From the diaphragm

DinnerDate
Down at the park the other day, chasing whatever I happened to come across, I did a few casual photos of unknown insect larvae, roughly 15mm in length, doing their best at denuding a small tree. Upon returning and unloading the memory card, I realized I’d caught some details I never expected to see, and certainly didn’t realize at the time, or I would’ve gotten a lot more images (and used a lens that provided for even closer work.)

Arthropods don’t breathe like we do, through a nose or mouth. They’re a little more direct, actually, and incidentally stand no chance of choking on their food. Along the sides of their bodies are small holes, called spiracles, which feed directly into tracheae that branch off and feed the tissues directly, or very close to it. These openings are subtle and hard to spot on most species, but if you see a line of spots or bumps periodically situated along the side of the body, you may be seeing them. In this particular case, however, I caught what was going on beneath the skin:

DeepBreathing
This is an almost full-resolution crop of the image at top, and the white lines branching all over are not markings, but internal anatomy. Those are the tracheae, and the brown spots at the intersections are the spiracles. This was, alas, the best image I got. While I returned to the park and collected a few specimens after seeing this pic, I did not immediately set up my studio, and by the time I did the effect wasn’t half as visible. I speculated that I was able to photograph this initially because the larvae were stuffing themselves blind on the leaves at the time, while a friend suspected this may have been immediately after molting and thus their exoskeletons were still transitioning. I also returned a few days later, ready to do more location shooting to see if that made a difference, but they were nowhere to be seen by that time. I haven’t been able to positively identify these yet, but my best guess is that they’re a member of the Argidae (sawfly) family.

Finds like this make you pay more attention to other images as well, so I noticed an odd spiracle pattern (I think) in another image while sorting my stock, taken without flash on a day with light overcast so I was shooting with the aperture wide open.

LastMinuteAddition
The green band, which assists in the camouflage of this larva very well, gives every appearance of having been jammed in among the line of spiracles, displacing them. Normally such cloaking patterns are just that, superficial coloration that reflects nothing anatomical, but here it almost seems to imply something deeper going on – though the spots near the borders may just be coloration. This one is identified, the larva of a unicorn caterpillar moth (Schizura unicornis,) and the peculiar spiracles are perhaps the only reason I might not toss this image, since it could be far better.

NorthSideWhile I was poking around the park trying unsuccessfully to locate the translucent caterpillars, I still took the opportunity to gather other images as well. We return now to days from the dim recesses of time, insofar as the blog is concerned anyway, and a post regarding the charmingly-named spiny oak-slug moth (Euclea delphinii.) I remarked then that my example images, working very well as camouflage, nevertheless reflected much less flamboyant coloration than most other pics I’d come across while trying to identify it. I haven’t spotted any other examples of this species (though admittedly may have passed quite a few of them without noticing.) Until now.

ColorfulOakSlug
As almost always, such bright colors aren’t an indication that it was intended for kids, but instead to make it memorable to potential predators, because it has a defensive response, in this case stinging (though I do not have firsthand experience of this – I can learn as well as any insectivorous bird.) This example was a little larger than the licheny one above, and it started me wondering if the bright coloration developed only after the larvae has found enough of whatever food source provides their defensive toxin. While trying to find if my speculation had any merit, I discovered that, since that previous post, there is now some hesitation among entomologists in naming a distinct species, since the adult Euclea delphinii is almost identical to the adult Euclea nanina, and the larvae are presumed to be as similar. I could have collected the specimen, raised it through pupation to adult, and made myself famous as the guy who resolved that burning question. As always, these turning points in my life are recognized only after they’ve passed…

And yes, that white spot that you see isn’t part of the larva, but something else – egg or parasitic mite, perhaps. This was another thing I missed until unloading the images. I should probably just bag everything I see anymore.

It’s… literature

Walkabout podcast – It’s… literature

By the time I finish this post, the article making the rounds may have already died its internet death, in which case I’m either resurrecting it or in denial (I’ll let you judge.) I’m referring to 20 Books You Pretend to Have Read, a post over at Book Riot regarding well-known works of literature that, apparently, carry more cachet than allure. The title says it all; for whatever reason, people are worried that others will think less of them for not having read some book or other. The comments, both there and in other places where the idea has been repeated, often consist of bragging about actually reading most of the list, interspersed with claims of failure to slog through some of the titles. It’s a reflection of our culture’s peculiar views on literature.

I’ll put this right up front: I’m not going to go into how many I’ve read, except to say that it isn’t many, and I couldn’t give the slightest damn what anyone else has. Read whatever you want, and do so for whatever reasons you want – but my suggestion is, do it because you want to, not because you feel obligated by someone’s impression of how important it should be.

Writing is just another art form, which means that certain styles will appeal to certain people, but not everybody. No one should have any reason to be self-conscious about their personal taste, and it bears no reflection on their intelligence or social graces. Somehow, though, we’ve developed the idea that certain books represent an ideal of some kind, the right way to write. This is especially amusing in regards to anything in English, which is such a bastard polyglot that guidelines for spelling and pronunciation are violated almost as often as they are followed, and the few truly original words are often frowned upon by those with more pomposity than sense. English classes, at least in the US but I suspect in Great Britain as well, have been the slowest in abandoning a ridiculous structure wherein there is a supposed authority to be followed – occasionally fostered by the arbitrary pronouncements of self-professed experts. We’ve been bombarded with platitudes over Shakespeare and Hemingway, Bronte and Fitzgerald and Tolstoy, to the point where we believe that if we don’t like these authors there’s something wrong with us – we’re uneducated Philistines or lacking in good taste or some such rot like that. We get the impression that we should at least appreciate such works, if not strive to emulate them as much as possible.

What utter pungent horseshit! Appreciation is an emotion, not a skill. While it is possible to provide insight into how some writer approached their ideas, and thus generate an interest in their style, attempting to coach someone into the ‘proper’ emotional reaction to anything is not going to end well – indeed, there is no shortage of resentment from being “made to read that shit in high school,” which is almost guaranteed to produce exactly the opposite of an appreciation of books.

One can argue that the goal of English Lit classes is only to introduce students to authors with an accomplished sense of style, but the bare facts don’t support this very well. Not only is it the same handful of authors every time, all of them from more than five decades ago, the attitudes plainly displayed by so many literati (and even the existence of that word) illustrate the stunning classism of the field – and a great example of the ‘art snob’ effect. By speaking of their appreciation of the classics, they pronounce their superior intellect and taste to the world at large, the judgment accelerating down the slope of their noses to reach the filthy masses so far below. Even the lengthy and especially turgid tomes bespeak the fortitude of these conquerors, as if traipsing through dismal swamps of prose is commendable rather than indicative of someone who has remarkably warped views of reading. If it’s a chore to get through, perhaps you should be in search of an author that actually holds your attention? Maybe, you know, that could be considered a mark of a good writer, even if “good” is strictly a personal judgment?

There are many cultures that resist change (says the guy sitting in North Carolina,) but none so adamant about it than the subculture of literature. While language is ever-changing, and with it the writing styles and usages of current authors, English classes perpetually harp on the ‘proper’ approaches, as if there was some authority to be found, and dare to grade students on how well they follow structures that will never again see use outside of the classroom – even if the student becomes a successful writer. I will readily admit, there is a lot to be said for making sentences flow smoothly and being able to communicate to the reader without confusion – communication is, after all, what language is for. Which is why weighing it down with rigid structure and byzantine rules is exactly what no one should engage in. Historical usages are fine, for anyone who has an interest in them, but people also used to shit in pots and dump them in the streets; we changed for good reasons, and clinging desperately to past practices from some vague sense of propriety is both pointless and counterproductive.

It used to be that reading was the mark of an educated person, still expressed in the phrase, “well-read.” This was before there was any other source of information dispersal, save for the lecturer or storyteller who was challenged to travel and experience as much as books could communicate. But this is a time long past, as old as many of those ‘classics’ of literature, and we have numerous sources of information available to us now. Reading can no longer be claimed to be the sole path to greater wisdom and thus a prerequisite for knowledge – admittedly, it still rates quite highly, but it’s quite possible to eschew reading altogether and yet produce a significant increase in understanding (it is as I type this that I realize I have to produce this one as a podcast.) And it must be noted that reading was always also a source of entertainment, of provoking the imagination and carrying us away. This particular aspect has long been known as the prime motivator in instilling language skills and writing ability; enthusiastic immersion in books solely for entertainment value still breeds the style and flow found therein, more than any lecture or required reading can do. The emotional involvement in the story attaches to the structure as well – which is again why required reading of ponderous works is precisely the wrong approach.

Being concerned over what anyone else thinks of our reading matter is exactly the same as dressing in the latest fashions: placing insecurity higher than sense, comfort, and entertainment. Read, instead, because it’s fun, or enlightening, or escapism. Drop the story that cannot hold your attention – such things deserve to be ignored. And never hesitate to treat the literature snob with pity, because they fail to grasp what reading can really do for us.

The title of this post comes from Mr. Pinsky in Throw Momma From The Train, but you certainly recognized it and didn’t need me to belabor the reference. And you undoubtedly caught the book on the coffee table at the end.
