The stochasticity of quantum interactions and the names of days of the week

It’s Wednesday today.  That’s a weird way to spell a day, and a weird way to spell a version of the name of the god Wotan or Odin, after whom the day is named (unless I am quite, quite mistaken).

Our days are peculiarly and seemingly haphazardly named here in the English-speaking West.  We’re not the only ones with inconsistent weekday names, but ours are certainly a strange hodgepodge.  Sunday and Monday are relatively straightforward:  they’re named for the sun and the moon.  Then, weirdly, we suddenly switch to Norse (!) mythology and name the next four days after four of the old Scandinavian deities.  Then, abruptly, we switch to a Roman god, Saturn, for Saturday.

This “names of the days of the week” thing was clearly not planned out.  It just sort of happened.  But that’s the way so many things occur in the real world—indeed, perhaps everything just sort of happens, and at multiple levels—not randomly but nevertheless stochastically and in a way that is functionally unpredictable, at least in its details.

The various quantum fields just sort of interact in ways that, at their lowest stable energy levels, give us quarks and gluons and electrons and photons and W and Z bosons and various neutrinos and a nonzero Higgs field that interacts with some (but not all) of the other fields.  The quarks and gluons just happen to form up stably into protons (and some neutrons, but neutrons are only stable within an atomic nucleus—they decay with a half-life of about ten minutes when existing freely).  And the protons happen to interact, via the electromagnetic field, with the electron field, and they stably pair up, and neutrons come into play “afterwards”, stabilizing larger atomic nuclei (though that’s not all they do).

Then, on large scales, the graviton field (if there indeed is such a thing, which is suspected but not certain) interacts with all the other fields, and where the density of stuff is slightly higher it pulls that stuff in towards itself, and where it is less, that rarefied stuff gets thinned out further as its components are pulled by neighboring stronger areas of gravity.

This process undergoes positive feedback—as stuff gets denser, its gravity gets more prominent, and that in turn tends to make the stuff get denser still.  And if there is any net angular momentum to larger collections of the stuff—and there almost always is some net angular momentum, since there’s only one way to have zero angular momentum, and there is a functionally limitless number of ways for it to be nonzero*—the stuff starts to rotate around a net common axis.

And then, of course, we get galaxies, and in those galaxies, we get stars, in which the interactions of the various quantum fields and gravity lead the protons and neutrons to get together into bigger clumps, some of which are quite stable (and the ones that aren’t stable simply don’t endure but transform into other states until they find ones that are stable).

Then stars run out of fuel, and the various field interactions and gravity produce various kinds of spectacular deaths, most of which involve scattering at least some heavier elements** out into the reaches of the galaxies.  Then we get next generations of stars, which (by the way) clump and develop angular momentum in a smaller but similar way to the galaxies.  And now, with heavier elements, we get planets, some of which are largely solid.

I think you know the broad strokes of the rest of the story.  If not, let me know.

Of course, this is a very general sketch of how stuff just came together to form the universe in which we exist, and there’s no indication that that is anything more than just small things—or esoteric things, really, such as quantum fields and their local perturbations—interacting with each other and making patterns on larger scales, much as water molecules can clump into fantastic patterns in the frost on windows or in snowflakes when they get cool enough.  Simple (well, relatively simple) rules at small scales can come together to produce surprising things at larger scales when they all interact at secondary, tertiary, quaternary and higher levels.

If you want to see how remarkable that tendency can be even in two dimensions, find a website that lets you play “John Conway’s Game of Life” and see how stable and active and interactive shapes can arise from even truly simple rules.

What was my point?  Sorry, I got distracted there for a minute.  Oh, right, I just meant to say that the things that happen and that all seem very real and important and even inevitable and fundamental are largely the products of stochastic processes interacting in ways that ultimately are far from being representable by any kind of linear equation.

It’s entirely possible and plausible that, if the rules of the quantum fields—or the specific types of quantum fields*** involved—were different, and thus interacted with each other differently, they might still accumulate into structures and functions on higher levels, and though they might produce a universe that would be all but incomprehensible to us, and in which we could not survive for an instant, they might nevertheless form structures and processes that could become what would have to be called “alive” and even “aware” and “intelligent”.

But in how many such universes would there be creatures that name the days of whatever passes for their weeks after various astronomical bodies (or whatever they have that is comparable) and random mythological figures from different places and times?

I leave it to the reader to speculate.

*There’s only so fast anything can be spinning, since no part of the spinning thing can exceed the speed of light.  Even black holes have a maximum angular velocity.  Nevertheless, both the angular velocity and the net axis of rotation can be more or less continuously variable.  If we can apply the real numbers—which ironically may not be possible in the real world—there is an uncountably infinite number of possible ways for angular momentum to be nonzero.  That makes zero really unlikely and unstable.

**Astronomers call any element but Hydrogen and Helium a “metal”, which is a very loose use of the term if you ask me.  I think many astronomers would agree, and sometimes I think I detect more than a tiny amount of embarrassment when they tell people that astronomical definition.

***Or the configurations of strings and branes if superstring/M theory turns out to be correct.

Thoughts on real versus virtual keyboards, books, and quantum teleportation

It’s Friday, and I’m writing this post on my mini laptop computer, because although yesterday I forgot it and had to use the smartphone, it was really quite nice the other day to be able to type for real and not tap around on some simulated keyboard with no aesthetic appeal, on which one cannot feel the keys responding to one’s touch (and which gives this one arthritic pain in the base of his thumbs).

I remember when the notion of such a virtual keyboard first appeared to me—this was in Star Trek: The Next Generation.  I thought the idea seemed terribly unsatisfactory despite being very clever.  I mean, I recognized the efficiency of it, but when the characters would read books and such things on their little portable “tablets”, it seemed almost heartbreaking.

Obviously, in a star ship in deep space, they’re not going to have room for a vast physical library such as the virtual one they clearly have in the ship’s computer.  It’s much like the fact that I have many more books in my Kindle library than I have in my physical living space (though I used to have way more physical books than I have current Kindle books).  But something is lost a bit, nevertheless, at least for me, with such virtual collections.

Actually, it just occurred to me:  in Star Trek, they use replicators to make their food and so on, applying the transporter technology to reproduce scanned items that include food.  Why could they not use that to replicate books as needed, then scan them away when they were done?

Of course, the quantum mechanics of potential real world transporter-type technology is such that you couldn’t mass produce anything from “scanning” any one particular item; as part of the required entanglement process for quantum teleportation, one destroys the quantum states of the particles in the original item (or person, if it’s a person, so Dr. McCoy was right to be leery of the transporter).

Also, the entangled particles used to reconstruct the item by creating a new set of particles in identical quantum states to the original, could not be kept in their transitional states indefinitely; such states are not inherently stable.  Even if they could be maintained thanks to advanced technology, once they were used to recreate the original item or person, those entangled particles would also have their own quantum states irreparably altered, and could not be used to make another copy.

You can never make more than one copy of a thing sent by quantum teleportation, The Enemy Within notwithstanding*.

Still, maybe the people in TNG could “scan” a bunch of real books, as if about to transport them using the ship’s transporters, and just…save them for later.  You couldn’t make multiple copies, again because the originals would not still exist after being scanned—as I noted before, such scanning destroys the initial quantum states of all the constituents of the scanned item (or person).  But they could just be singly stored in the “buffer”, saving the quantum state of the entangled particles used to apply quantum teleportation.

But wait, I hear you say, storing all those books “in transition” would entail a tremendous amount of stored quantum information that would need to be maintained in its entangled state indefinitely, at presumably great cost in data and energy.  Not only that, one would have to have the equivalent of the mass of those items in the ship at all times, no matter** what.

You are very clever, and you are, of course, correct; it wouldn’t be efficient in any sense, and would add to the power requirements of the ship.  Also, in any serious disruption of the ship’s stability and power—such as happens in nearly every episode, so more than twenty times a year on average—much of that quantum information would probably be lost.

Maybe it really doesn’t make practical sense to try to do such a thing.  After all, I’m the person who has bemoaned the incredible data wastage necessary to store audio, let alone video, files rather than the much more efficient written word.  And I have not changed my mind on that set of subjects.  I could record a video, or even an audio, of me reading the words of this blog post, and it would have a file size in the hundreds of K at least; for a video, it would probably be many megabytes in size.

Meanwhile, my average blog posts, as stored in Word, are 16 to 20 K in size.  It’s quite a difference.  Even just using the RAM of this small computer (4 gigabytes) I could load up as many as a quarter of a million blog posts (assuming nothing else were in the random-access memory, which in not the way things work).  That’s about 250 million words.  Even I am unlikely to write that much during my lifetime.

More importantly, with the written word no one has to look at my ugly mug (though I will admit that my voice is absolutely lovely, so it might be worth hearing any audio file I produce…Ha-ha, just kidding).

Anyway, as I noted, it’s Friday, and I’m almost certain we’re not working tomorrow—I’m inclined to say that, even if the office is open, I’m not working tomorrow, but I tend not to follow through on such ultimata, because I’m a pushover—so there won’t be another post until Monday, at the earliest (barring, as always, the unforeseen).

I hope you all have a good weekend, but at least I know, as I pointed out yesterday, that you will have the best weekend you possibly can, since whatever happens becomes inevitable as soon as it happens, and it may have always been so (if quantum superdeterminism is correct).  Of course, that means you will also have the worst weekend possible.  But for most weekends, that’s a comfort.  For most such weekends, you could honestly say, “Well, if that was the worst weekend I could possibly have had, it’s not so bad.”

Usually, you could honestly say and feel that.  And it’s very likely that this weekend will be one such usual weekend.

Have a good one.

*In any case, that episode is really more of a fable than anything truly science fiction.  It assumes a bizarre kind of dualism between body and mind and a further, cleanly divisible dualism even in the mind itself, which in the episode is split into discrete but very broad personality aspects that can be separated out into different bodies.  It’s an interesting exploration of the tension between aspects of a person’s character, and engages speculation about whether a dark/violent side is a necessary aspect for a good leader.

Therefore the Moon, the governess of blogs, pale in her anger washes all the air

Hello and good morning.  It’s Thursday, the first of May*, the beginning of yet another stupid month.  They just keep coming, on and on and on, so irritatingly relentless that I find myself wishing for the elimination of the Moon and the destabilization of the Earth’s rotation and orbit just to break the tedium.

I know that would inconvenience a great many other people, though, so I’m not going to try to make it happen.  To be fair, it would be much “easier” to alter the Earth’s rotation than to shift the Moon.  A decent-sized asteroid collision at the right angle could alter both the rate of Earth’s rotation and its angle to the ecliptic.

Of course, such an impact would have devastating consequences for almost everything and everyone on the planet’s surface.  So that’s a win-win scenario!

I’m kidding.  But I often fantasize about wiping out all life as we know it, because none of it is truly benign and it’s all futile and will always be marked broadly by fear and pain and other suffering, because all those things are evolutionarily vital (in the literal sense).  I shouldn’t choose that for other people, though, so I probably would never do such a thing even if I could.

Thinking back to earlier, though, I’ve been pondering the question of just how one would move the Moon in its orbit, and I thought about the reflectors up there in the old Apollo landing sites, still used (last I checked, anyway) to measure the distance to the moon with great precision.

There have long been discussions about how to alter the course of an asteroid that looked to be prone to intercept the Earth.  One way might be to vaporize a portion of the asteroid, causing its “outgassing” to act almost as a rocket propellant, and by Newton’s third law (or, equally valid, by the law of conservation of momentum) the asteroid would shift its trajectory in the direction away from the artificial outgassing.

Well, what if one were to train powerful lasers at one site on the surface of the Moon**?   The fact that the moon is tidally locked with Earth means it’s constantly showing the same face to us, so one could keep focusing on the same portion of the surface.  One could study the albedo and absorption characteristics of the surface of the Moon to try to pick the best wavelength for causing “outgassing” of that surface, and that outgassing would propel the moon away.

It would be a slow process, since the Moon is big, and shifting its orbit significantly would require the delivery of quite a bit of energy, but that’s okay.  One could set up a single laser (or pair of them on opposite sides of the Earth, or more if one desired faster effects) perhaps solar powered and using ordinary telescope-style tracking equipment and software, to train the lasers always on the same point on the surface of the moon.

Gradually, the Moon would shift away from Earth (you’d need to keep adjusting your aim a bit), more quickly than it currently is, and eventually:  lunar liberation!

Of course, even given the abysmal state of science on Earth (and particularly in the US right now), people would eventually notice the Moon moving, and they might even notice the “outgassing”.  But a lot could be done before then.

If one wanted to have a much quicker effect, or rather, a more instantaneous effect, one could develop a large depot of antimatter, which we know how to make in particle accelerators.  Storing antimatter is challenging, of course; it must be kept within electromagnetic fields in high vacuum, since it will annihilate if it encounters its matter counterpart.

Still, with enough time and patience and care (and money), one could gradually accumulate a large stockpile of antiprotons and positrons, perhaps stored adjacent to each other so their mutual electrical attraction makes containment slightly easier.  Then, when one had gathered enough, one could launch it toward the moon in a fairly standard rocket‒it wouldn’t need to be manned, and it certainly wouldn’t need to return to Earth.

Release your tons (I would guess) of antimatter onto the surface of the Moon, perhaps at the center of “mass” of its face that points toward Earth, and watch the fireworks!  There would be complete annihilation of matter-antimatter in a release of energy far more extreme than any mere nuclear weapons could produce.  Heck, if you wanted to bypass the whole Moon process, you could just accumulate your antimatter here on Earth over time, maybe near some damage-multiplier like the ice caps or near a super volcano or something, and release the containment when you’re ready.

In a typical nuclear explosion, less than one percent of the mass involved in the reaction is “converted to energy”***.  In an anti-matter reaction, ALL of it would be converted.  Imagine releasing hundreds of times more energy per kilogram than the most powerful nuclear weapons.

Of course, antimatter is absurdly expensive to make, but economies of scale might help that.  It’s not as though one would be expecting a profit‒unless one went the Bond villain route and used one’s anti-matter bomb to hold the Earth for ransom, which is a thought.

That’s enough of that madness for now.

Speaking of madness, today begins “Mental Health Awareness Month”.  I would say that I’m already aware of mental health in a general sense, I just don’t have much personal familiarity with it.  Mental illness, mental dysfunction, mental dysregulation, these are things with which I am more personally acquainted.  I’m only too aware of them.  Physical health falls into a similar position.

All right, well, before I discuss more ideas about how to alter or eliminate all life as we know it‒I’ve many such ideas, I’m afraid‒I should draw to a close for the day.  In case you can’t tell, I’m not right in the head, am I?  So this is a sort of appropriate month for me, especially coming as it does right after Autism Awareness Month.  Batman only knows what will happen next.

*Also known as May Day.  I wonder how that came to be used as a distress call, as in, “Mayday, mayday, we are going down!”

**Alternatively, one could, in principle, use a very large array of adjustable mirrors on Earth, and they could be shifted to reflect sunlight and focus the reflections on one spot on the moon, but to get a strong effect would require a worldwide collaboration or at least acceptance of these mirrors.  It’s hard to see that happening.

***I used “scare” quotes because technically it’s all energy to begin with, it’s just changing form.

I’m sorry, I don’t have the energy for a Shakespeare based title

Hello and good morning.  It’s Thursday, and though I don’t particularly feel like it, I’m writing a blog post because it’s Thursday.  This doesn’t necessarily mean I’m going to write one tomorrow or Saturday (assuming we* are open, which we probably will be, since it’s rare to be closed two weekends in a row).  As far as I know, I will not.

I don’t really have any energy or impetus to write much.  I’m trying.  I’ve been rereading my fiction to try to stimulate myself, but so far it’s obviously not doing the trick.  I reread first The Chasm and the Collision, then Son of Man, then The Vagabond, and just yesterday finished rereading Mark Red.  I’ve also reread a few of my short stories.  But, though I’ve enjoyed rereading my stuff as far as it goes, it’s not really doing anything as far as catalyzing any desire to write, whether fiction or nonfiction.

I think things would be much more positive if I were able to get a good sleep (at least one night) and especially if I weren’t in daily, increasing pain.  I’d be tempted even to try ketamine if I thought it would really help, though there are some cautionary examples in the mainstream media that would give me pause.  Heck, I’d practically be willing to try full-on PCP if I had good reason to think it would provide lasting relief without causing worse problems.

Of course, there’s the rub.  All of these things that can provide even temporary, real relief have a range of side-effects that would make my situation even worse than it is.  Yes, I freely admit that my life could get worse.  It’s almost always true that things could be worse than they actually are.  But that doesn’t mean they’re good.

I’m just so weary, so tired of every day being dominated by both physical and psychological pain.

Actually, I feel that the last adjective there should be “psychical” not “psychological”, since the latter term refers to the study of the psyche, and I don’t have pain or suffering that involves the study of my psyche, just pain in my psyche itself.  Still, the common usage, for what it’s worth, seems to lean toward “psychological”.  Then again, current common parlance refers to psychological problems as “mental health”, as in “Are you suffering from mental health?” which makes little sense.

I wish I could wrap myself in some kind of life-support cocoon and undergo some form of metamorphosis, like Adam Warlock in the comic books.  Hell, just being able to sleep for a while seems like it’s a ridiculous, superstitiously foolish notion, on a par with the expectations of the Heaven’s Gate cultists, who thought a space ship was coming to gather their souls (and was supposedly hiding in, I think, the tail of the Hale-Bopp comet).

I want to rest.  I want to stop being in constant pain.  It’s been going on for more than twenty years, and it’s tainted every aspect my existence.  It has contributed to everything from the breakup of my marriage, to my arrest and incarceration, and to my inability to sustain or create any kind of close relationship of any kind.

The people “closest” to me are hundreds to thousands of miles away, and I have no doubt that if they were physically closer, a kind of Uncertainty Principle-like process would occur, such as what makes the momentum/energy of, say, an electron greater and greater the more tightly you try to pin it down, until more and more of its wave function leaks out and the probability of it being elsewhere‒even on the other side of the universe, so to speak‒dominates over any local presence.

I’m probably not explaining that very well, I’m sorry.  But I don’t even have any will to watch science videos or to read science books or what have you, let alone to go into any rigorous discussions thereof.  I’m just making the point that I’m much better for other people from a distance than from up close, with the function approaching a singularity (of negative infinity) as the distance from me shrinks toward zero, rather like some logarithmic function.  This graph (of log base 2) demonstrates why, from a certain distance, it can start even to be pleasant to interact with me, though with diminishing returns…but woe betide anyone who drops below one unit of distance.

Okay, that’s enough for today.  It’s probably much more than enough.  I’m sorry to be so tedious; believe me, no one gets more tired of me than I do of myself.  At least all of you can just go read something else by someone else, or do something else entirely.  Not I.  I am stuck with being and enduring the miserable git that I am every waking moment.  And waking moments make up far too great a proportion of the times of my life.

Have a good day, if you can.

TT…FN, I guess.

*By we, I mean the office at which I work.  While I have no problem joining with you, my readers, into a collective, first person plural pronoun, I simply have no idea what y’all’s work schedules are.

But darkness and the gloomy blog of death environ you…

Hello and good morning.

If you’re a regular reader, you know what day it must be if I’m using that opening phrase.  It’s Thursday, the third one in December of 2024 AD (or CE if you prefer).  There’s only one more week until Boxing Day, so keep your training up!

You should probably take a rest on the day before Boxing Day‒“Boxing Eve”, if you will, though there are other names for the day, I’m led to understand.  In many places, people take Boxing Eve off from work, so it might be a good time to kick back and relax your body, to let it recover from your training.  Get a decent meal with plenty of protein, but abstain from alcoholic beverages* entirely.  And keep the refined carbs to a minimum.

Also, of course, you should not listen to songs like Baker Street, or Careless Whisper, or Turn the Page.  While it’s slightly controversial, many experts agree that one should avoid sax before a fight.  You might even want to avoid Feels So Good, by Chuck Mangione, for though he plays the flugelhorn, not the saxophone, the sound is similar, and science is not entirely certain which aspect of the sax’s sound interferes with boxing ability.

It may simply be that it leaves a person too relaxed and at ease to be at their fiercest.  So, perhaps one should just avoid soothing music altogether, and stick with environments that keep one hostile and alert.  Remember what Palatine said about anger:  “It gives you focus…makes you stronger.”

Fortunately, many people find the traditional Boxing Eve celebrations with family quite stressful and irritating.  You gotta hold on to that fury.

All right, enough of that silliness.

Next week is also the beginning of Hanukkah, the first night of which begins on Boxing Eve (also known as “Christmas”, which is a curious amalgam of Saturnalia and the Nordic Yule grafted onto the celebration of the birth of the founder of an obscure Jewish sect).  None of this stuff is really of any consequence to me, though; I’m not celebrating anything.  What cause would I have to celebrate, and with whom would I do so?  Nothing and no one.

I’m frankly discouraged that it looks like I’m going to be around to see a new year.  Of course, every day is, in principle, the beginning of a new year, just as every second begins a new hour, and every day is the last day of your life so far, for whatever that’s worth.  I wouldn’t think it would be worth very much, but who knows?  Worth is a very subjective thing.  It can be intersubjective, but unless you’re talking about things like food, water, air, and shelter, most values are related to the valuer and the culture such a valuer shares with other valuers.

Stepping farther back, even the seemingly inherent value in things like food, water, air, and shelter is predicated entirely on the needs of living creatures‒subjects, if you will.  Life itself is an entirely subjective value, at least in that sense.

Please note that I’m not saying that reality is subjective!  One’s personal experience of reality is, to some degree, subjective, but reality itself is what it is, not what individual persons believe it to be…unless those persons happen to believe it to be as it is, whether through luck or discerning thought and perception.

Anyway, this is all pointless.  I tend to try to cloak my inner darkness in humor and whimsy for other people’s sake.  This might fool you into thinking you’re seeing someone who’s not really unwell, not really so down, not really doing all that badly.  Similarly, an active accretion disk might make you think a particular astronomical object is inherently bright, staggeringly so even.  But that radiance is merely the conflagration of all the matter spinning and colliding and accelerating and trying to squeeze into limited, rotating spacetime before passing the event horizon.

With the exception of Hawking radiation‒which is smaller and fainter the larger the black hole‒the event horizon is a surface of absolute darkness, at least from the outside.

You might ask why there could not be something even darker than a lack of light, perhaps some form of antilight.  But, no.  Photons are bosons, and bosons are, in a sense, their own antiparticles, so the opposite of light is just light.  Under normal circumstances, bosons don’t self-annihilate, though they can destructively interfere, in a fairly straightforward, wave dynamics kind of way.

This blog post, and the blog itself, is in a sense my accretion disk.  It may be hot and sometimes bright, in an ordinary incandescent way, but so many things burn and flare, hot and bright and fierce and beautiful, even as they fall to ashes, never then to shine again, reduced to a state of maximum local entropy.

And, at the heart of the black hole‒at least in GR, avoiding quantum mechanical concerns**‒lies the singularity.  It’s appropriate.  The center is a singular entity‒like a singular person‒which does not entail anything but an end to time itself, the complete obliteration of anything and everything and everyone that it encounters.

No wonder people stay away from such individuals.

*In some cultures, people tend to drink alcoholic beverages on Boxing Eve.

**Which you can’t really do, to be honest; see my point about reality not being subjective.

There’s the respect that makes calamity of so long blogs

Hello and good morning.  It’s Thursday, and so it’s time for another weekly blog post.  Last Thursday I was out sick, so I only posted a very brief, almost telegraphic announcement of the fact that I wasn’t going to write a “true” post that day, and I said that I might write a true post on Friday if I was feeling better.  Of course, I was not feeling better by Friday, so there was no such post.

I’ve nearly recovered from my acute illness—probably some respiratory virus, but nothing too terribly severe—and now I am more or less back on my normal schedule.

Speaking of being “back”, though, my back has been acting up severely this week, and in an atypical fashion.  I’m not sure what triggered it.  Possibly it’s just due to being sick, with the coughing and the lying around more than usual and so on.  Possibly it’s something else.  Anyway, I’ve had to go to a combination of near-overdoses on my various OTC pain medications, and that’s not wonderful.  It got so severe yesterday that I was actually saying out loud that, if it didn’t improve, I was going to have to find some relatively high parking garage nearby and jump off it.  I was not exaggerating, as I think was obvious to those around me.

It’s easy enough to wonder why I don’t do that anyway, given that there is very little in my life that’s positive, and what positivity exists is episodic, and it can’t make up for the constant negatives of pain and illness and sleeplessness and depression and so on.  The closest I come to any comradely activity is streaming YouTube videos of people reacting to songs or movies that I like.  It’s almost, but not quite, exactly unlike watching a movie with a friend who has never seen it before.

Speaking of paraphrasing or otherwise referring to The Hitchhiker’s Guide to the Galaxy, I’m most of the way through the first run of editing Extra Body.  There’s a long way to go, since I usually do as many as seven such iterations before considering my editing done.  I figure by that time I’ll usually have lost any proprietary affection for a story and it will begin to bore me, so it’ll be easier to cut out extraneous material.

That’s the principle, at least.  I don’t know how well it’s worked hitherto; I’m too deep inside the process to trust my evaluation.  I did at least transcribe the material I had written so far, in passing, on HELIOS, so that if/when I’m ready, I’ll be able to pick up writing that by hand in its first draft.

Extra Body is my first non-horror story in a while (unless you count the beginning I made on writing The Dark Fairy and the Desperado, which is certainly not horror, but is also certainly nowhere near done, if it ever will be).  It’s hard for me to tell if it’s a good choice to have reverted to a sort of lighthearted science fiction story set in the modern world, but at least I was able to squeeze the first draft out.

Of course, I’m paring down the word count as I go.  As I’m sure is obvious to all of you, I get rather wordy when I write, especially when I’m using the computer keyboard, since I type quickly and usually can do so more readily even than I can speak out loud.

I’ve been reading some more books about quantum field theory (and related subjects) lately.  It’s still very intro level stuff, of course, but either because recurrent exposure to increasingly technical material is gradually sinking into my head, or because I’m just getting a tiny bit “smarter” overall over time, I’m actually finding some of it more familiar and understandable than before.

I must say that I was a little bit proud of myself not too long ago when I was thinking about how complex numbers are represented using a two-dimensional plane, with internally consistent mathematics and whatnot, and I wondered if one could have three-part complex numbers.  I soon realized that only even-numbered ones would work, and then I learned that these were indeed a thing (i.e., quaternions) and that indeed only even-numbered versions of such things can work.  Of course, it’s very difficult to visualize something that has four dimensions, so you just have to do the math, and I haven’t started to work on or learn that seriously, but I played with some “higher order” complex-number multiplications a few times, which was how I saw that only even-numbered ones, with separate “imaginary” roots would work.

On a vaguely related note:  I was listening to Sean Carroll’s podcast yesterday evening.  He was speaking to Doris Tsao, a neuroscientist who specializes in facial recognition and processing centers of the brain, and she mentioned that the attributes of a face can be thought of as many-dimensional, in the sense that there are numerous “variables” that can be represented about any given face, and that they effectively comprise a higher-dimensional space.

Then she turned the matter around and noted that there are apparently those who consider using such things as faces as ways of intuiting mathematical or related systems with higher dimensions, thus representing them in ways that the human mind is capable of visualizing.  I though that was a fascinating notion*.

It reminds me little bit of the concept of the “memory palace”, a mnemonic/rhetorical tool that originated in ancient Greece (so I understand) in which one associates the aspects of, say, a speech one is going to give with imagined artifacts or decorations in some imagined hall or room, so that the aspects of that speech can more readily be remembered and brought to mind when needed.

There are several fictional characters, most notably Hannibal Lecter and the BBC’s Sherlock, who use rather exaggerated versions of these memory palaces.  The one described in Hannibal is more coherent than the one in Sherlock, but they both take great liberties with how the concept was originally used.  Nevertheless, for the longest time, thanks to the amusing tableau** Thomas Harris described for how Hannibal Lecter had “stored” Clarice Starling’s (fictional) home address, I could readily reconstruct her address at will.  I think I may still be able to do it.  It should be something like “#33 Tindall Ave, Arlington, Virginia, 22308”.  If anyone wants to check my recollection, that would be welcome.  I’m not certain I got it right.

I’ve usually found such mnemonics more trouble than they’re worth.  It’s easier for me to connect concepts in the real world, building mental models of the way things work rather than trying to memorize.  This means I probably don’t learn as quickly as some do, but I learn deeply when I do, and it’s easier to connect one model to another and to spot analogies and similarities and possible connections between systems that might at first seem unrelated.  That was quite useful in medical practice, as I’m sure you can imagine.

Oh, I almost forgot:  Welcome to the first day of August in 2024!

That’s all I have to say about that.

Apparently the summer Olympics are currently taking place, but I’ve been unable to muster any interest in them, though I used to love them, and I find that the manufactured controversies about some apparent misconstrual of the opening ceremony or some such (and the juvenile ripostes by political antagonists of the original misconstruers responding to the supposed offense) all serves simply to reinforce my feeling that not just the human race, but indeed all life of any kind, is a bad idea.  Thank goodness for the apparent inescapability of the second law of thermodynamics.

Anyway, I feel I’ve been meandering about here, randomly bouncing from topic to topic, without any consistency or coherency, so I’ll bring this to a close soon.  I fear that this once-weekly blog posting suffers from the fact that there are topics I probably would have brought up as solitary daily blog posts when I was doing them, but that I now want to try to squeeze in here.

I just can’t write (or edit) new fiction and write daily blog posts too, not while I’m forced to keep my day job.  If anyone out there wants to pay for my living expenses and support me so I can both write new fiction and write daily blog posts while still studying physics and programming and the like in the meantime, please, let yourself be known!  I’d be pleased to hear from you.

Otherwise, I’m pretty sure none of this is going to last very much longer.  My pain and dysthymia and alienation and insomnia are increasingly unpleasant, and there are fewer and fewer things in my life that compensate.

Here’s to Macbeth’s proverbial last syllable of recorded time.  L’mavet!***

*It does come up against difficulties when considering the notion of orthogonal axes of vector spaces being able to be rotated into one-another.  It’s hard to see how one could intuitively consider rotating the variables of, say, eye size and cheek color into one another, or what an inner (or “dot”) product or cross product of two such variables could mean…though with the latter, it makes the use of the “right hand rule” an amusing invocation of a slap in the face…or at least poking someone’s cheek.

Here’s to the father I tried to be

To death, L’mavet.

L’mavet, L’mavet, to death.

Death has a way of releasing us

Luring and teasing us

Drink L’mavet, to deeeeeaaaath…”

That’s as far as I got, but I did only work on it for about five minutes, so, it’s not too bad.

If idle blog will once be necessary, I’ll not sleep neither. This mortal house I’ll ruin…

Good-o and hell morning.

It’s Thursday, so I’m writing my formerly standard (and potentially newly standard) weekly blog post today.  Huzzah.  Admittedly, I last wrote a blog post on Monday, so there have only been two blank days since I posted, but it still feels odd.  My daily blog posts are almost never worth reading, anyway, though, so it’s not a huge loss.

It was slightly nice to let myself not feel pressured to write a “report” on my progress these last few days.  I also didn’t push myself to write more than one page a day.  Historically, that has often nevertheless led to me writing quite a bit more per day, but not this time.  Over the last two days, I’ve written a total of 1,361 words on Extra Body, bringing it to its current total of 57,886 words (88 pages).  I just haven’t had much energy for writing, or for anything at all.  That’s even relative to my usual level of energy.

I say that, but I have been trying to study some mathematics and physics.  I’ve been doing the Brilliant course on intro to linear algebra, which is quite interesting, and should help prepare me for more in-depth work in quantum mechanics/quantum field theory and (most important to me) General Relativity.  I need to review and improve my calculus as well.  I also got the e-book (PDF) of Advanced Theoretical Physics by the guy who runs the Science Asylum YouTube channel.  He does a really good job explaining things on his channel‒including things I already understand well, so I know he’s rigorous and thorough.

I’ve also been reading Leonard Susskind’s Theoretical Minimum book on Special Relativity, with plans to move toward the subsequent one on General Relativity (and to circle back to the one on quantum mechanics).  And, of course, I’ve also been reading Sean Carroll’s two Biggest Ideas in the Universe books.  Basically, I want to ground myself in the concepts and renew and improve my mathematics skills before I get into real study of GR, using Sean Carroll’s textbook (I already own it and Gravitation) and possibly some other recommended texts, and also some university level quantum mechanics and quantum field theory.

One reason for this is:  I’ve long wondered just what would happen if one were to accelerate a space ship to close enough to the speed of light that its relativistic length contraction and relativistic mass put it below its Schwarzschild radius (at least relative to outside observers), which should mean it should become a black hole.  But of course, it’s not a simple spherical mass, so the solutions for the equations might be much more complicated and lead to unexpected outcomes as in the Kerr solution for spinning black holes.  This is the most realistic black hole model, since basically all black holes spin, and often do so quite energetically.  Conservation of angular momentum applies to collapsed stars just as it does when a spinning skater spins faster as the skater’s arms are pulled in.

I have a secret fantasy that a spaceship situation such as I described above might allow a ship to turn itself into a wormhole instantaneously if everything is done right, and achieve something that is effectively faster-than-light travel.  But even if that’s not workable, I’d like to know what would happen in such a situation.  I know this is not idle thinking, because there was real curiosity whether, if there really were curled up dimensions that are large enough, particles at the LHC might achieve relativistic mass enough to become tiny black holes*.

This is far from the only question I would like to understand better about GR.  I want to understand, deeply, the mathematics that makes a cosmological constant produce “repulsive gravity” and thus expanding spacetime.  I’m actually starting to get a little inkling of how that works, but only an inkling**.  I need more.

I would like to understand everything, of course, everything that there is to know…but only through the dint of my own work.  I would never want just to be given knowledge.  How lame and boring that would be!

I also have been able to (re)read some fiction amidst all this‒The Belgariad, by David Eddings.  I picked up near the end of Queen of Sorcery and am now in the first half of Enchanter’s Endgame.  It’s nice to be able to read at least these fiction books that I haven’t read in a while 

Basically, I’m frantically grasping at straws‒panicking in my weird, quietish way‒trying to find something, some reason, to keep me going.  I fear it’s not working, though.  The downward pull is too strong; I’m orbiting in the inner accretion disk of my personal black hole, and unless I can be pulled out by someone or something‒for I cannot do it on my own‒I will soon enter the “plunging region” where orbit is no longer possible, and nothing remains but to cross the horizon.  Every single day I yearn for everything to be over.

It doesn’t help that my sleep has been rotten, even by my own standards.  And my chronic pain always interferes with everything.  And my tinnitus is just galling, keening away like a permanent near-the-ear mosquito, but higher in pitch, especially now that I have a bit in my left ear as well as the major tinnitus in my right ear.  It makes the various other noises of the world feel all the more chaotic.  And I’m very much alone in my head, and in my life.  I feel like the only member of my species, like that last passenger pigeon that lived, companionless, in the Cincinnati Zoo for a few years before dying.

Meanwhile, the weather down here in south Florida is thoroughly sloppy, with rain and flooding and everything that goes with them‒such as the Internet being out where I live‒leading to my long commute being more unpleasant than usual.  At least it’s cooler, though (in temperature, not in fashionableness).  There were a few times during the night last night in which, when I started awake‒as I do several times most nights‒I realized that the air conditioner wasn’t even running!  That’s rare in June in this part of the world.

Oh, and I mentioned Substack a few days ago.  Well, it turns out that, technically, I already have a Substack account, since I follow a few other writers and thinkers thereon.  So I guess, if I so chose, I could write stuff there and set it up with a paywall.  Of course, actually, I could do that here on WordPress already, I think, and loyalty would suggest that it would be the better choice.  Of course, I could set up a Patreon account and link it to my work here and to my YouTube channel and so on.

All these thoughts are pipe dreams, though.  I don’t honestly expect any of them to come to fruition‒they’ll just drop to the ground like most of the fifty-six trillion mangos in south Florida, merely to rot there and attract fruit flies.

We’ll see, I guess.

Meanwhile, I’m scheduled to work this weekend, so I’ll have two more days of fiction writing this week and three next week before my next scheduled blog post.  It’ll be almost the equinox next Thursday, and of course, this coming Sunday will be Father’s Day.  I wish that were a holiday I could enjoy; being a father is the most important and greatest thing I have ever done.  But that all went bitterly off-kilter, and I crashed and burned, and right now I’m just surviving in the wasteland near the wreckage, fantasizing about a rescue or an escape, but knowing more and more every day that such a thing is vanishingly unlikely.

Anyway, enough.  This is getting too long.  I hope you all have a good week and a good weekend.  If you’re a father, I hope you have a great day Sunday, and for those of you who have fathers who are still around and who deserve it, I hope you get in touch with them at least and make sure they know that they matter to you.  Men are expected to be stoic about love and other feelings…but men also die by suicide in about three or four times as great numbers as women.  Correlation does not necessarily imply causation, but it sure doesn’t rule it out, either.

*This was never a worry, just to be clear, even if it had happened.  A tiny black hole that size would decay almost instantly via Hawking radiation.  But that would (or should) produce an essentially random shower of particles, not the usual decay products of the original particle.  Alas, no such events (or event horizons) occurred, so if there are curled up extra dimensions, the LHC didn’t get energetic enough to probe them.

**That sounds like the word for a baby pen, doesn’t it?

There’s a divinity that shapes our blogs, rough-hew them how we will

Hello and good morning.  It’s Thursday, and as I promised‒or threatened, depending on your point of view‒here I am, writing my weekly blog post as before, back when I was regularly writing and publishing my fiction.

I’m not sure what topic(s) I should cover here, today.  I rarely seem able to plan these posts in advance, and when I do plan them, I don’t think they often come out very well.  That’s from my point of view, of course; maybe other people have found my planned posts excellent and wish I would write them more often, but if so, they haven’t given any clear feedback.  So, I don’t really know what will happen from now until the end of this blog post.

Of course, if the universe is deterministic, then whether I or anyone else knows it or not, what I will write is already a certain thing, as is the fact that I don’t know it‒indeed one could legitimately claim that it “already” exists in a sense, particularly if one is invoking the picture of Special and General Relativity and the “block” spacetime concept.

However, the Copenhagen interpretation (if that’s the correct term) of quantum mechanics states that wave-function collapse is truly “random”, and so the future is not determined, at least at the smallest level.  But if the wave function truly collapses, then that would be the only fundamentally irreversible temporal process known in physics so far, and that seems suspicious to me.

I’ve been reading the original EPR paper and thinking about this subject at least a little bit lately.

Of course, in a way, the Everettian “many worlds” interpretation of quantum mechanics would say that the future really is determined, but that at every instance of decoherence, the wavefunction becomes subdivided into waves that no longer interact with each other directly.  People interpret this as if new universes were coming into existence each time, and that’s a decent way to conceptualize it, but to me it seems misleading.

To my mind, it’s just waves that are traveling along in “parallel” and not influencing each other.  But that’s not really any different from the sounds of two separate conversations happening in a crowded room‒maybe one involves a group of people discussing a recent sporting event and another gaggle is talking about some new show on Netflix.  Maybe the conversations are even in different languages.  The sound waves propagate from each conversation independently, and though there may be places where troughs and crests pass and add or subtract for an instant, locally, they are very much different processes.  But there is no mystical invocation of “new universes” such as what troubles some people about Everettian quantum mechanics because of a misunderstanding of Occam’s Razor.  There are just separate, “parallel” things happening within the same overall universe.

That’s not a perfect analogy, of course.  The “waves” of the quantum mechanics are more complex* than sound waves, and are more fundamental, and once they decohere, it seems they are far less likely to interact with their other “branches” than are even sound waves of parallel conversations in different languages.  But even those are more separable than we think.

We have an exquisitely evolved capacity to parse the information out of human conversation, decoding the waves without thought, and so we don’t think very often about how astonishing that process is.  If aliens who communicated only by light flashes were trying to interpret such a set of conversations, they would have a daunting task, indeed.

Just think about how hard it has been even to decode the communications of dolphins and whales‒highly intelligent and social creatures that clearly communicate with each other.  And these are our fellow mammals from the same planet, who also use sound for communication!  We vastly underestimate the complexity of what we’re doing when we understand conversation and other noises, because our auditory processing systems do it without our conscious intervention, and they have been honed over hundreds of millions of years by the brutal and pitiless sieve** of natural selection.

Likewise, we thoroughly underestimate the complexity involved in catching a pop-up fly ball, or a thrown football, or the process of walking, or of throwing a ball, or of finding a specific item on a cluttered desk.  It shouldn’t surprise us that even if the future “division” of the universal wave function seems random, it can be utterly deterministic, and in that sense each branch “already” exists.  But each “branch” that no longer interacts with others after an instance of decoherence will “feel” to given humans*** as if it were the one and only “universe” and that all others have collapsed out of existence somehow, when they’re really just there but not interacting anymore with the person in question.

Maybe I’m wrong, of course.  I mean, I’ve been right before, but not often enough to make it my default presumption.

Anyway, there you have it, the stuff about which I was “destined” to write, though I had no specific plans.  That’s fair enough.  “Life is what happens while you’re making other plans,” as the saying goes.

Speaking of plans, though, I plan to write tomorrow and Saturday**** on my fiction (probably just on Extra Body).  I may take my laptop with me to do it; the experiment with my smartphone seems to be working okay (see my reports from Monday, Tuesday, and Wednesday), but it doesn’t feel quite as “natural” to me, still.  Who knows, though?

Only Laplace’s Demon® (Quantum Version™) knows.  But of course, that entity would feel, if anything, less “free” than those of us who know not yet what is to be and know not fully what has been.  For an entity that can see every detail of the past and the future laid out deterministically and in full detail is utterly incapable of taking any action on such knowledge‒for its own actions are as determined as all others, and it “knows” this.  Indeed, it cannot but know it.

Ignorance is not bliss, but it does at least give you room to improve, and that can be ego syntonic.

Have a good week, if such is your destiny.

*Ha ha, that’s a little physics joke there, when you think of how quantum wave functions involve complex numbers.

**Mixed metaphor alert!  How would a sieve hone anything?  Oh, well, I’m not going to change it; it works too well to communicate my meaning.

***And the very process of “feeling like something” is extraordinarily complex, and we only really understand the bare rudiments of how this happens.  This relative ignorance engenders the propagation of nonsensical, conceptually vacuous ideas like panpsychism and the like, and the pseudo-mystery of the “hard problem” of consciousness.  Well, it is a hard problem in a sense, but not the way philosophers of consciousness seem to express it, as far as I can see.

****I think I will be working Saturday, but I’m not certain, because of the highly atypical thing that happened last Saturday, with the office being closed.  This coming Saturday will be my son’s 24th birthday, and I will now literally have missed half of his life more or less completely.  That’s his preference, not mine, though it started as a consequence of my own misadventures‒our personal wavefunction decoherence if you will.  Still, when enough people repeatedly decide they don’t really like having you around or interacting with you too much, you have to think there must be some powerful causes for the consistency, especially when you don’t even really want to be around yourself.  So, I am profoundly sad about the state of things, and I miss my children terribly, but I have to conclude provisionally that they’re making a reasonable decision.  At least I “talk” to my daughter from time to time, and that’s not a small consolation.

“What hears with their ear? The abyss between the stars.”

It’s Friday, and presumably I’m not working tomorrow.  I don’t think I will work even if it turns out I am working, if you take my meaning.  I’m too tired.  My coworker was out sick yesterday, and so were some other people.  Unfortunately, I’m not sick, apart from the chronic, sick-in-the-head sort of sickness with which you all are no doubt familiar.

I’m writing this on my phone, though I brought my laptop computer with me yesterday.  I had thought to whip out a draft of a blog post on it then write a page of Extra Body before editing the blog post, but now I’m having to wait so long for an Uber that I decided just to take one into the office, anyway.

I hate how Uber always tries to get you to do the “share a ride” thing.  I wish they would stop suggesting it to me, or that there was some setting in the app that would let me tell them never to offer me a shared ride.  In the unlikely event that I want to share a ride, I’ll select that option from the start.  Stop “nudging” me.  It’s unpleasant enough for me to have to deal with the fact of the driver; I don’t want to share the back seat with some other stranger.

Actually, if I’m going to “share a ride” I’ll just take the flipping bus and pay pennies on the dollar, as the saying goes.  I really should just do that, anyway.  Uber and Lyft are bad habits, and not cheap ones.  In fact, I ought just to be walking to and from the train in the mornings, since riding the bike makes my back and hips absolutely scream with pain afterwards (which is very disheartening).

I took half a Benadryl again to try to help me sleep last night.  I don’t think it actually helped me rest, but I do feel groggy and incoherent this morning, so it’s had some effect, subjectively speaking.  I don’t know if you readers can tell, though.  It may well be that, from your point of view, I’m always more or less equally incoherent.

I feel that I’m becoming more and more decoherent with every day.  I wonder if my wave function is collapsing.  Can the Born Rule be applied to a human…or to whatever I am, for that matter?

I’m being silly, I know.

In a sense I suppose the Born Rule could apply to an individual if that individual makes a decision based on a quantum measurement.  There is, apparently, an app that allows you to do just that; it’s connected to a beam splitter in some lab somewhere, through which one photon at a time is being sent, and it tells you which direction a given photon ends up being measured.  Thus, you can make a truly random decision if you so desire‒as far as physics can currently tell, a fundamentally random decision.

A coin flip or a die roll is not fundamentally random, though for practical purposes it may as well be.  We don’t have access to enough information to predict a given outcome on a fair coin or die, but in principle it is possible.  Whereas with a photon going through a beam splitter, we have a completely, in-principle, unpredictable process.  The Nobel Prize was recently awarded to Aspect et al for their experiments that tested and confirmed the Bell inequalities, thus disproving anything but the most esoteric forms of “hidden variables” descriptions of quantum mechanics.

Sorry.  That was one of my weird tangents.  I’m a bit too mentally fatigued to restrain myself very well.

This sort of thing happens in real life, too.  Yesterday, I was talking about something to do with some song that came on the playlist to my boss, and I went off on some esoteric tangents about music and stuff, and I could finally just see his eyes start glazing over, so I pulled up short.  Then I caught myself looking up to see if I could find someone else in the office with whom to share some of my trivia and my thoughts about songs and various other things.

I caught myself in time, though, and retreated to my desk.  Then someone asked to change the music playlist to some pathetic new artist and related crap that wasn’t nearly as interesting.  I briefly put in my earphones and listened to some of the Feynman lectures on physics to block out the noise.  That didn’t work for long, though, because I kept having to do office stuff that required interaction with living humans.  And then, of course, I had to work through lunch, because three people got sales all at once, just as lunch arrived.

I hate my life.  I really do.  It’s not just work that I hate‒at least that involves some purpose, however unfulfilling.  I also hate my time “off”, my lack of friends, my apparent inability to be a friend, and my inability to be able to fucking sleep, along with many other things.

I’m so tired of it all.  I’m tired of writing this blog, but I feel stressed at the prospect of not writing it.  I don’t get tired of writing fiction so much as feel it’s an exercise in futility, and so I generally don’t get started anymore.

Then again, everything in the universe, ever, is just an exercise in futility.  As Charles Halloway said*, “Where do you come from?  The dust.  Where do you go to?  The grave.”  The same could be said of every planet and star and cluster and galaxy and every bit of the observable universe and everything else that may be beyond it‒metaphorically speaking, anyway.  Dust is something within the universe, as are graves, so it seems unlikely that the universe could come from dust.  But I think you get my point.

It’s that there is no point.

There may be no firm fundament but is there a fun firmament?

It’s Tuesday morning, now, and I’m writing this on my laptop computer, mainly to spare my thumbs, but also because I just prefer real typing to the constrictive and error-ridden twiddling of virtual buttons on a very small phone screen.

Speaking of the day, if the Beatles song Lady Madonna is correct, then it’s still Tuesday afternoon, and has been at least since last Tuesday, since “Tuesday afternoon is never-ending”.  Of course, if Tuesday afternoon really is never-ending, then it has been Tuesday afternoon ever since the first Tuesday afternoon.  From a certain point of view, this is trivially the case.  After all, every moment after 12pm on the first Tuesday that ever happened could be considered Tuesday afternoon—or, at least, they could be considered “after Tuesday noon” if you will.

Enough of that particular nonsense.  I only wrote that because there’s nothing sensible about which to write that comes to my mind.  But, of course, in a larger sense, there is nothing “sensible” at all.

There are things that can be sensed, obviously.  I can see, hear, and touch this computer, for instance.  If I wanted, I could probably smell it, though I think its odor is likely quite subdued.  But I mean “sensible” in the more colloquial, bastardized, mutated sense—as in the word “sense” just there—which has to do with something being logical, reasonable, rational, coherent, that sort of thing.  Indeed, it has to do with things having meaning.

Deep down, though, from the telos point of view, there is no true, inherent meaning to much of anything, as far as anyone can see.  Certainly there’s no meaning that anyone has ever demonstrated or asserted convincingly that I have encountered at any point in my life.

Of course, people have beliefs and they have convictions, and humans assign meanings to various things.  All the words I have used in writing this post so far, and all the words I will use henceforth, have “meanings”, but those are invented meanings.  There is nothing in the collection of letters—nor indeed in the shapes of the letters themselves, nor the way we put them down on paper or a screen—that means anything intrinsically.  They were all invented, like justice and morality and the whole lot of such things.

That something is invented doesn’t mean it isn’t real, of course.  Cars are an invention, and only a fool (in the modern world) would deny that cars are real.  But they are not inherent to the universe; they are not in any sense fundamental.

In a related sense, even DNA and the protein structures for which it codes are very much not fundamental; they are quasi-arbitrary.  Of course, one cannot make DNA or RNA or proteins out of substrates for which the chemistry simply will not hold together.  But the genetic code—the set of three-nucleotide-long “letters”, the codons, in the genetic code that each associate with a given amino acid (or a stop signal, or similar) as they are transcribed into proteins—is arbitrary.  There’s nothing inherent in any set of three nucleotides that makes it associate with some particular amino acid.

This sort of thing took me quite a long time to realize as I was growing up and trying to understand biology and chemistry and such.  What, for instance, was the chemical reaction with, say, adrenaline that made things in the body speed up and go into “fight or flight” mode, as it were?  How was it that aspirin chemically interacted with bodies and nervous systems to blunt pain?  How many possible chemical reactions were there, really?  It was mind-boggling that there could be so many reactions, and that they could all produce such disparate effects on various creatures.

When finally I was shown the real nature of such things, it was definitely a scales-dropping-from-eyes moment.  There is nothing inherent in the chemistry of DNA, or of drugs or hormones, that produces their effects.  There is no inherent “soporific” quality to an anesthetic.  You could give a dose of Versed  that would kill a human to some alien with a different biology, and at most its effects would be those of a contaminant.

It’s all just a kind of language—indeed, it’s almost a kind of computer language, and hormones are just messengers*, which are more or less arbitrary, like the ASCII code for representing characters within computer systems.  Likewise, there’s nothing in the word “cat” that has direct connection with the animal to which it refers.  It’s just keyed to that creature in our minds, arbitrarily, as is demonstrated by the fact that, for instance, in Japan the term is “neko” (or, well, it sounds like that—the actual written term is ねこ or 猫).

Of course, there are things in the universe that, as far as we can tell, are fundamental, such as quantum fields and gravity and spacetime itself.  But even these may yet peel away and be revealed to be arbitrary or semi-arbitrary forms of some other, deeper, underlying unity, as is postulated in string theory, for instance.

The specific forms of the fundamental particles and forces in our universe may—if string theory and eternal inflationary cosmology for instance are correct—be just one possible version of a potential 10500 or more** possible sets of particles and forces determined by the particular Calabi-Yau “shape” and configuration of the curled up extra dimensions of space that string theory hypothesizes.  So, the very fundamental forces of nature, or at least the “constants” thereof, may be arbitrary—historical accidents, as much as are the forms and specifics of the life that currently exists on Earth.

And what’s to say that strings and branes and Calabi-Yau manifolds are fundamental, either?  Perhaps reality has no fundament whatsoever.  Perhaps it is a bottomless pit of meaninglessness, in which only truly fundamental mathematics are consistent throughout…if even they are.

I’m not likely to arrive at a conclusion regarding these matters in a blog post written off-the-cuff in the morning while commuting to the office.  But I guess it all supports a would-be Stoic philosophical ideal, which urges us to let go of things that are outside our control and instead try to focus on those things over which we have some power:  our thoughts and our actions.

Of course, even these are, at some deeper level, not truly or at least not fully ours to control—we cannot affect the past that led to our present state, after all, and the future is born of that present which is born of that past over which we have no control.  But, for practical purposes, the levers that we use to control ourselves are the only levers we have to use.

We might as well keep a grip on them as well as we can, and not worry too much about things that are not in our current reach.  Though we can try to stretch out and limber up, maybe practice some mental yoga, to try to extend that reach over time, I suppose.  But that’s a subject for some other blog post, I guess; this one has already gone on long enough.

*For the most part.  Things like cholesterol and fatty acids and sugars—and certainly water and oxygen—and other fundamental building blocks do have inherent chemical properties that make them useful for the purposes to which bodies put them.  Then again, words can have tendencies that make them more useful for some things than others, too.  “No” and “yes” are short and clear and clearly different sounds, for instance; it makes sense that such words evolved to be such important, fundamentally dichotomous signals.

**That means 10 x 10 x 10 x 10… until you’ve done that multiplication 500 times.  You may know that a “googol” is a mere 10100, and that in itself is already roughly 20 orders of magnitude (100,000,000,000,000,000,000 times!) larger than the number of protons and neutrons estimated to exist in the visible universe.  So 10500 is a number far vaster than could ever be written out within the confines of the universe that we can ever see.  There’s not enough space, let alone enough matter, with which to write it.  It’s a googol times a googol times a googol times a googol times a googol!
