Now let it work. Mischief, thou art afoot. Take thou what blog thou wilt.

Hello and good morning.

It’s Thursday, and I walked to the train station this morning, but I did not walk back to the house from the train station last night.  It had just gotten so late, and I was tired, and I wanted to get back to the house early enough that I could relax and at least try to get to bed at a reasonable hour, even if I never do sleep through the night.  But I committed to walking this morning, and I fulfilled that commitment.  Bully for me!

I must be getting in better shape, or maybe I just left earlier or summat, because even though I stopped to get a beverage* and tried to take my time after that, I still arrived in time to catch the train that leaves twenty minutes earlier than the one I usually get when I walk.

My feet and knees and ankles are doing tolerably well, so the shoes I did choose seem unlikely to lose when it comes to my long-distance walking.  I also find‒curiously enough‒that wearing spandex knee braces helps keep my ankles, especially my right ankle, from acting up.  It seems that something in the way I move (ha ha) when my knee stability is not optimal is adding torsional, irregular forces to my right ankle and Achilles tendon.

It’s often quite surprising just how non-straightforward the source of damage or pain is in the body compared to where one feels the discomfort.  Spandex helps with some of this because it adds one’s sense of surface touch to one’s ongoing awareness of the position of one’s joints from within**.  The sense of surface touch is much more precise than many of our other senses, which makes sense***, since it has much more of a role to play in guiding our targeted moment to moment actions regarding injury, obstacles, insects that might bite, and so on.  It may also be that spandex helps decrease excess fluid accumulation in a joint by providing counter-pressure in a fairly uniform way, and this can certainly be expected to improve a joint’s stability.

I’m sure that’s all quite boring.  Apologies.  I don’t mean to be tedious; it’s just a talent I have.

Switching topics:  I like listening to good podcasts (or audiobooks) while I walk, and this morning I listened to the AMA (ask me anything) podcast for the month on Sean Carroll’s Mindscape.  Well…I listened to part of it.  His AMAs are usually three or four hours long, because he tries to get through as many questions as he can, and he tries to answer them as carefully as he can.  It makes for some very interesting listening, because he is a theoretical physicist who also works in philosophy.  Formerly at CalTech, he is now at Johns Hopkins and also works with the Santa Fe Institute and is just in general broadly interested and interesting and quite thoughtful.

I still like Sam Harris’s podcast (and his guests) a little bit better, but that’s not particularly important.  I like them both, and I learn a lot from them and their interlocutors.  I have noted that I like long podcasts but prefer short videos, which is interesting and seems on its face odd to me.  Perhaps it’s simply that one can listen to a podcast while doing any of a number of other things, but not so with videos.

Anyway, it’s nice to be able to hear about and potentially learn about interesting things while walking.  It’s also occasionally fun, in a rather silly way, when someone asks a reasonably complicated question to which I know the answer and then to hear Sean Carroll say the same thing I would have said (this is far from common, but it does happen).  Of course, people rarely ask him questions about medicine or biology, because he is not a specialist in those areas.  If they did, I would probably usually be able to give better answers than he, but that would hardly be particularly impressive.

It’s also hardly important.  I’d rather be listening to someone talking about things I know less about than they, because that’s how one learns.  I sometimes try to do brief “podcasts” or “audio blogs” of my own, but I don’t get the impression anyone ever really listens to any of them.  I don’t know.  Maybe they do.

Oh, I wanted to address the very nice comment left by a reader yesterday, in which‒among other things‒he said that he liked the idea of the manga that I had mentioned.  I just want to make clear, although HELIOS started out as a comic book idea, and then became a manga idea later (at around the same time I thought of mangas for Mark Red and for The Dark Fairy and the Desperado) I don’t see myself ever actually doing a manga now.

I think that the work involved in making a manga‒from the initial script to the storyboarding to the penciling to the inking to the screen tone‒would all be just too much and it would be difficult to work into my schedule.  Perhaps if someone were paying me to do it full time, I might try.  But I don’t think that’s very likely.

I really only have the notion of perhaps writing a “light novel” of HELIOS, rather akin to the light novels that are popular in Japan which are often turned into manga and or anime.  Mark Red and DFandD and HELIOS are probably stories that lend themselves more to manga/anime style settings, but I am much more of a prose fiction writer, even though I do draw sometimes.

Anyway, I think that’s probably enough for today.  I intend to keep doing my walking and hopefully that’ll help me be healthier overall.  I’m also trying very hard to completely eliminate sugar and most starches or refined carbohydrates from my diet; that certainly helps me feel physically better.  We’ll see how everything goes.

Maybe, if I do well and my mood starts to improve consistently, I will start to write fiction again, on HELIOS or on DFandD or on Outlaws Mind or on Changeling in a Shadow World or even on Neko/Neneko****.  Who knows?

I hope you have a good day.

*The water fountains at the Hollywood Tri-Rail station have been “temporarily out of service” for, I don’t know, it must be most of a year.  I would very much like to be able to get a drink of water when I get to the station after walking 5 miles, but I think the people who run the place are happy to try to coerce people into buying something from the ridiculously overpriced vending machines at the station.  I would not seriously consider doing that unless my life depended on it, and I might not do it then.  I’d even rather pay twice as much somewhere else than buy something to drink at the station when they have water fountains but just haven’t fixed them.

**This is called proprioception, as most of you probably know.  It’s not a very precise or reliable sense, being quite coarse grained, and it also seems to deteriorate with age and with damage to joints.

***Sorry, that wasn’t meant to be any form of pun, but it is the best way I can find to put it right now, so I won’t change it.

****The story of a cat (named Neko, the Japanese word for cat) who is devoted to her human, a lonely but upbeat and gainfully employed young man (who is fond of anime and manga and light novels, among other things).  When the man buys an odd, exotic fish, the cat intends to eat it, being a bit jealous and also just having the instinctive desire to do so.  But then, the fish reveals to the cat that it is magical (evidenced well by the fact that it can talk and that the cat can understand it), and if the cat spares its life, it will grant her a wish.  She agrees, and chooses to be able to become a human woman (at will) to be a potential companion for her human.  Surprised when she first encounters him, he asks her name, and she stammers, Ne…Neko.  He takes this as her having the Japanese name Neneko, and she accepts that.  Thus, the title.

Apologies for a blogless Monday

I was out sick with some form of enteropathy* yesterday, so I didn’t write a blog post.  I frankly haven’t done much of anything that’s in any way productive since Friday, and I’m not sure I did anything productive then.  I hope no one was too bereft by not being able to read my writing for three days (ha ha).

I’m now sitting at the train station, waiting for the train to the office (well, it doesn’t actually go to the office, but I think you know what I mean), not looking forward to the fact that I’ll have to do extra catch-up work from both Saturday and yesterday.  I really don’t want to have to deal with any of it or with anything at all.

I don’t know why I keep doing anything whatsoever.  I can speculate on certain causes, of course‒habit, the evolved drive simply to continue to survive, a dislike for causing inconvenience to other people, all that sort of thing.  Also, I guess there is the idiotic hope that maybe, just maybe, I will find some answers, some meaning, or some solutions to at least some of my problems.

Honestly, when I get sick like over Sunday through yesterday, I get the wild hope that maybe I’ll need to be hospitalized, and while in the hospital, I’ll be able to get some help for my psychological issues as well as my physical ones.  It’s stupid, I know.  I need to stop hoping for anything.  Hope is a waste of my time.

Ironically, it’s hope that keeps me writing about the fact that I’m having problems going on, problems dealing with my issues and my loneliness and my depression and insomnia and pain and all that crap.  I hope that somehow, by talking about it, I’ll either arrive at some insight or ideas or some semblance of understanding that might lead to some modicum of peace.  Or I hope that someone out there in the WordPress world‒perhaps it should be called the WorldPress‒will have some new ideas or insights or some help to offer.  Or maybe some old friend of mine will read what I write and will reach out and offer a hand or something.  I don’t know what they could do, or what I could do.  But anyway, it is hope that keeps me writing, I guess.

But it’s getting old.  I’m getting tired of it.

When I don’t just dwell on morosity (I don’t know if that’s a proper word), I write about weird shit, like I did on Friday.  I could write about current events, I suppose, but most of those are discouraging and boring.  It’s basically about as fun as writing about the interactions of a very large colony of baboons from the baboons’ points of view.  Baboons don’t want to admit to themselves that most of their choices and motivations are almost entirely simple primate dominance, mating, and social jockeying behaviors.

Humans really are just baboons with delusions of grandeur, some of which are excusable, many (perhaps most) of which are not.  They’re weirdly built and strange to look at, with very rare exceptions.  They think their culture and society and civilization were made somehow, deliberately‒by them it sometimes seems they imagine, though that cannot be possible‒when really, it all just sort of happened and continues just to happen, like any weather phenomenon or termite mound.  This is nothing of which to be ashamed‒it’s the nature of everything as far as I can see‒I just find the hubris disgusting and inexcusable.

Even nature itself seems just weird and rather twisted and horrifying when I look at it these days.  Maybe part of it is that I’m down here in Florida, but when you look closely at the very ad hoc, cobbled together, misery-laden natural world, in which even green plants compete ruthlessly against each other, while insects gnaw the tree trunks, and birds eat the insects and cats eat the birds (when they can) and meanwhile ten thousand other such painful and fear-ridden interactions are taking place in every acre, at all levels, from viruses to bacteria, to yeast, to protozoa, to slime molds and lichen and moss and mold and mushrooms up to grasses and bushes and trees and worms and snails and arthropods and fish and amphibians and reptiles and birds and mammals…everything ultimately just churning away at low entropy energy and converting it into high entropy energy…well, it all seems horrifying and discouraging and very, very dark.

Everything in the world seems alien to me…which I guess must mean that I am alien, since everything else is just there, doing what it does, being what it is, and I’m the one that finds it all daunting and repulsive.

I often bring up the concept of Sisyphus, and it now occurs to me that, maybe, Sisyphus is gradually wearing away the mountain on which he rolls his ever-falling boulder, slowly grinding it down until, finally, it’s level, and the boulder will no longer roll but will stay where Sisyphus puts it, and that will be the state of the universe at very high entropy (I want to say at maximum entropy, but I don’t think there is a maximum overall entropy**).

Of course “maximal” entropy is a state that can go on for a very long time.  It’s like the fable (as told by the 12th Doctor) in which the Emperor asks a shepherd boy to tell him the meaning of eternity.  The shepherd boy says there is somewhere a mountain of pure diamond.  It takes an hour to climb and an hour to go around.  Once every hundred years, a tiny bird comes along and sharpens its beak on the diamond mountain.  And when, after so many repetitions of that once-a-century sharpening happens that the diamond mountain is finally worn down to nothing…then the first second of eternity will have passed.

Even once the “heat death” of the universe comes to pass‒assuming that is what will come to pass‒and all is a haze of elementary particles, barely above absolute zero in an endlessly expanding but empty spacetime, which will come potentially after more than 10 to the 100th power years, that will only be an infinitesimal instant at the uttermost beginning of the eternity of nothingness.

In that quantum vacuum, even a direction of time will have less meaning than would any possible sense of up, down, left, right, forward, and backward in the heart of one of the intergalactic supervoids, in which not even a single distant star or galaxy could be seen with anything but the strongest telescope on long exposure.  To the human eye, in a supervoid, all would be blackness and emptiness in all directions, and in the heat death, that would apply to time as well.  With no change, the past and the future are indistinguishable.

Yet, eventually, new universes, or Boltzmann brains, or other esoterica might yet come to be.  Eternity is a long time.  Or maybe they will be found to have been in what seems to be the future but which is, eventually, the past of some universe with an opposite-pointing “arrow of time”.

Anyway, my point is, the universe is weird and harsh and the hubris of self-important creatures would be laughable if it were not so nauseating.

I don’t think I can do all this much longer.  My stop is coming up soon.  Have a good day.

*You can look it up.

**There is a maximum amount of entropy that can be fit into any given region of spacetime, and that is the Bekenstein-Hawking entropy of the area of an event horizon of a black hole that would enclose that region, expressed in square Planck lengths.  Actually, if memory serves, it’s the logarithm of that surface area (probably the natural logarithm).  If you tried to “add more entropy” to such a region, the black hole would grow, and the horizon would just get larger…you wouldn’t get more entropy “within” the given region.

If I have veil’d my blog, I turn the trouble of my countenance merely upon myself

Hello.  Good morning.

I really wished that this would be the Thursday blog post that I would title with the unaltered Shakespeare quote, “The rest is silence”, which is Prince Hamlet’s last line before he dies.  Then maybe I would share a brief clip from the video for the Radiohead song No Surprises, the part where Thom Yorke sings, “I’ll take a quiet life, a handshake of carbon monoxide, and no alarms and no surprises.  No alarms and no surprises.  No alarms and no surprises.  Silent.  Silent.”

Unfortunately, this will probably not be my final fit nor my final bellyache.  I certainly still feel compelled to write this today.  I woke up quite early, as usual, and lay in my room just staring about, wondering if there was any excuse I could give for not going to the office, and whether staying at the house would be in any way better than just going in.  Neither seemed to be the case.  So, finally, I got up, showered, and decided to take an Uber to the train very early.  In fact, I arrived just as the first train of the day was pulling into the station, though I made no attempt to catch that one, since it was functionally impossible.

And now, here I am, sitting and sweating and writing.

A weird thing did happen as I was getting ready to go this morning.  I put in my earphones and pulled up YouTube Music and chose my playlist “Favorite Songs”, with YouTube doing its little self-promotion about some new, unrequested service it now provides or something, in which I had no interest.  Anyway, I tapped the “shuffle playlist” option, and the song/video that came up first was my own song, Schrodinger’s Head.  But the song that began playing was none other than the aforementioned No Surprises.  It continued to play, overtop of my own song’s logo and screen, even when I backed up to the beginning of the song.  It didn’t correct itself until I’d skipped to the next song and then came back, at which point it was my own song that started playing.

That’s a strange glitch.  Does it mean that the program loads “video” and “sound”, at least in YouTube Music, as two separate processes?  I usually just go for the song rather than the video option (when that’s available), but I have always guessed that doing so simply involved the suppression of the video portion of the file in some sense.  But I’ve not ever seen a mixed song and video from different sources.

Not that I’m bothered.  It’s far from insulting if a Radiohead song presents as if it were my own.  Well, it might be insulting to Radiohead, but not to me.

Anyway, I didn’t actually listen to either song at the time.  I realized that what I really wanted was actual silence, and just leaving the earphones in but not playing anything is the closest I can come to that.  Of course, tinnitus means I haven’t experienced full silence for about 15 years, at least not in my right ear, but I can try to come as close as possible.

My pain wasn’t as bad yesterday during the day as it had been on the previous two days, and that’s definitely a good thing, though now it’s acting up more severely again.  That’s not really anything new.

As I stood outside waiting for the Uber, the air was as usual in the morning lately:  stagnant and still in addition to being hot and humid.  But far up and away to the east and south were high clouds, and there was rather frequent lightning to be seen, then and when I was riding to the train.

We used to call that “heat lightning” and I think people imagined it was something different than usual lightning, but my current understanding is that it is the same electrostatic phenomenon, merely much higher in the air (where I suspect the resistivity is lower, though I may be wrong about that…in any case, there would be more cosmic ray bombardment to seed ionization paths for lightning to follow).

Of course, one never hears thunder from heat lightning.  Maybe that’s because it’s so high and far that the sound is thin even to begin with, since sound travels more slowly and less effectively through less dense media.  And then, of course, as it hits the lower atmosphere, trying to enter a denser medium (with faster propagation speeds) it might be unable to penetrate.  Indeed, there might* be a phenomenon analogous to total internal reflection, the process that, among other things, allows fiber optic cables to work with essentially no signal loss.

When light is traveling through a dense medium, like glass or diamond, in which it moves much more slowly relative to its speed through air or vacuum, and it comes to an interface where it would pass out into a much less dense medium‒where it would travel much more quickly‒if it strikes at too shallow an angle, it will not exit its current medium at all, but will instead fully reflect, effectively without any loss.

My first thought was that it was the opposite situation for sound traveling from high, thin air to lower, much denser air.  But then it occurred to me that it’s not the density of the medium that directly causes total internal reflection, or any refraction, really.  It’s the differential speed of propagation that causes refraction and total internal reflection**.  And sound travels more quickly through a denser medium, not less quickly, whereas light does the opposite.  So, comparatively slow sound in thinner, upper air, coming to denser, lower air, might reflect if it arrives at a shallow enough angle.

It’s somewhat like being below the surface of a pool.  We know that sound travels much better and farther in water than air, but if your head is underwater, you may not be able at all to hear people talking who are standing near the pool, and you might not even be able to hear loud ambient music (unless a subwoofer is in contact with the ground/floor and thence to the pool).

I think I’m more or less on track with this as at least part of the explanation for the fact that one never hears the thunder that accompanies very, very high lightning.  Of course, some of it could simply be ordinary attenuation, since the intensity of sound falls off as the square of the distance (as with light, also…this is one of those physical facts of reality that is directly caused by the geometry of three-dimensional space, nothing more esoteric and nothing less profound).  But that doesn’t seem to me to be an adequate explanation for why one never hears the sound of “heat lightning”.

Well, that’s enough ado about nothing for today.  It’s more than I expected or wanted to write.  I mostly just wanted to write some form of goodbye.  But the horrible, terrible, inexorable pressure of habit and routine in someone with a particular type of nervous system can be nearly as potent and irresistible as the laws of reflection and refraction and geometry.  I can only seem to escape such habits when I am forced by external circumstances to do so, but then new habits and routines‒compulsions, really‒take the place of the old ones.  I try to procure useful habits when I can, but one cannot entirely pick and choose such things.

I fear my only escape will happen when I actually die.  Of course, if time and space are fixed and super-deterministic, then even that might not actually be an escape.  As far as my experience goes, it might just lead to me starting over at the beginning, like a video being played on a loop.

Nietzsche actually used that notion (obviously not based in Einsteinian concepts, but it doesn’t have to be) as the basis for a thought-provoking question:  if you knew for certain that, once you die, you would then live your life over and over again exactly as it happened this time around, how would you change your current and future behavior?  Is your life now one that would horrify you to repeat infinitely, or would it be okay?

Inquiring minds want to know, I guess.  Or maybe not.

no surprise

*This is just me speculating in real time.  If anyone knows the correct answer, please let me know.

**Thus the frequent demonstrative analogy used to teach about refraction:  a row of soldiers marching side by side coming at an angle to a place where they leave hard, firm ground and enter deep mud, which will tend to change the angle of their movement.  Alternately, one often encounters the story of a lifeguard running across the beach to save someone drowning, needing to judge the best place to enter the ocean to minimize the overall time taken to reach the swimmer.  Too much time in the water slows the lifeguard too much, too much time on land makes the path longer, and thus also slows the lifeguard.  The lifeguard’s path of least time turns out to be exactly analogous to what light does when refracting through differing media.  A brilliant, “for-the-layperson” account of the quantum mechanics behind this is given in Feynman’s QED: The Strange Theory of Light and Matter.

This post was written on Sunday night. That may be the most interesting thing about it.

I’m starting this blog post on Sunday evening, which is obviously not when I usually write my blog posts.  I’m writing it on my phone, because I didn’t bring the mini laptop with me when I left work early on Thursday, and though I could use my full-size laptop, I have no desire to bring it along with me tomorrow.  I tentatively plan to walk to the train in the morning.  I’ve given up on the boots; I think they do exacerbate my back pain.  It’s very sad, because I like them, but there’s not much that can be done about that.

I still have a bit of a low-grade fever this evening, but that’s okay.  I’m not particularly interested in trying to protect my health.  I’ve been here in my room‒with some outings to the store of course‒since Thursday evening.  I’m not very good company, not even for myself, I’m afraid.

It’s rather amusing; I have recently gotten suggestions for videos on YouTube about dealing with trauma from being in relationships with someone with Narcissistic Personality Disorder, and probably also because I liked a video by a self proclaimed NPD person who did a good video about the Doctor, especially the 12th Doctor, as an example of someone with autistic characteristics.

Anyway, I don’t think I’ve been in any relationships with anyone with NPD,  and I certainly don’t have anything akin to NPD myself.  Quite the contrary.  When I was younger, I used to sort of pretend to be an egotist and to have a huge self-image and I (jokingly) pretended to think I was great and wonderful.  I’m pretty sure no one who knew me really took me seriously.  I’ve certainly never acted like a real narcissist or psychopath or anything, but there have been times when I envied them their self-love.  I’ve even tried‒especially when I was in prison‒to do auto-suggestion with a mantra saying, “I love my life and I love myself.”

After a while, though, I couldn’t even think the words in my head, not while trying to mean them, not while trying to believe them.  It feels like telling a foul and terrible lie.  I am often amused by people and literature and the like that speak of the (supposedly) ubiquitous sin of self-love.

I don’t think I have ever loved myself, not in my entire life.  Not in my oldest memories do I have any sense of feeling that I liked or loved myself.  It almost feels like a category error.  I never thought of myself as the kind of entity or being or concept such as that to which love might pertain.  I don’t think of myself as some identity, really.  Who am I?  I’m just the specific being that is asking that question, that’s all, whatever that is.

I’m a weird, complex four-dimensional braid in spacetime, comprised of the swirling patterns of all the particles that come together and form this long time-space tornado, bits coming into it and going out of it, everywhere, all the time, the pattern changing as one moves from past toward future, but only gradually.  And the overall pattern is continuous, and presumably will last for a bit longer before it can no longer be self-sustaining, and then it will fray and scatter and dissolve, the former bits going to be temporary parts of various other spacetime braids.

L’dor v’dor.  Amayn.

I certainly feel continuous with the kid crying in bed with his leg aches when he was little, and who always kind of was watching everything from outside.  Don’t get me wrong, I’ve had a good upbringing and a loving family.  I had good friends in school, and we did fun and interesting things together.  And I loved learning things, and I still do love that.  But I’ve always been weird, I know that.

I’ve felt…well, I wouldn’t say I felt different because it wasn’t really about any comparison.  Again, it feels almost like a category error.  I recently coined a term unsane as a contrast to the term “insane”, to mean something, someone, to whom the very concept of sanity doesn’t really apply.  I’ve often sort of thrown that (in my head) as an epithet at the deeds and behaviors of so many people and things around out there in the world.  But maybe it really applies to me.

I feel like maybe I’ve always been at right angles to every dimension of all the people around me.  But I don’t think I’ve ever loved myself, not even for a moment, though there are plenty of other people and things I love.

I think the person I’m most like, in raw aspects, is my Dad.  I had the advantage of being the youngest of three children, and so had support and people I could watch to see how things were done (and sometimes to see what not to do, what sorts of things didn’t tend to work).  My Dad was the eldest child in his family, so I guess he had to pick up a lot of things on his own.  But to his credit (and to hers) my Mom was with my Dad from when they were married until the day he died.

But he was often the one who in many ways made sense to me, even when I was really mad at him.  He was the only one who ever wanted to spend as much time at an exhibit in a museum or a zoo as I do.  Everyone else always moves along way too fast.  But somehow it’s not as much fun to see such things alone.  

I don’t know that for certain, actually.  I don’t think I’ve ever tried to go to a museum or library by myself.  The closest I’ve come is going to a bookstore by myself, and even that is just blah.  When I’m by myself, I have no will to get out and do much of anything at all.  I don’t do things for myself.  I have no desire to do things for myself.  I wish I didn’t have to obey the urge to eat or drink or breathe for myself.  It’s all quite boring.  I don’t even like to look at myself in the mirror*.

I don’t know why I’m writing this.  It’s just what this entity does at this point in spacetime, because of the various internal and external interactions among the various forces and “particles” in this particular spacetime weather pattern.  Why does that eddy in that river swirl about in that particular way at that point in a stream?  Because of physics.  There’s nothing deeper as far as I know.

That doesn’t mean I think it’s simple.  It’s ridiculously complex.  No system‒as I think I’ve said before‒can ever be complex enough to understand itself completely, for that would require an infinite expansion of complexity.

Anyway, this is already long enough for a full blog post.  If this is not the last paragraph**, it will mean that I’ve added something tomorrow morning.  I don’t know whether that will happen, but if you’re reading this, you will know the answer, but it’s further down the braid than where I am now.  I’m planning to walk to the train in the morning.  If I get hit by a car (or a bus or a truck, I’m not picky), or if I have a heart attack or a stroke, or if I’m sicker than I feel and collapse because of it‒none of which would break my heart, except perhaps literally‒I’m unlikely to add to it.  Maybe I’ll put this up on WordPress and set it to auto-post in the morning.  That way it will go up whether I’m alive or dead or something in between, and some mystery will remain.  I guess you all will see.

[Addendum:  I made it to the train station, and I did walk.  Better luck next time.]

*Though, curiously, I find listening to my own songs and covers relaxing.  Damned if I know why.

Universal heat death will be cold, but today it’s too hot and yet too air conditioned, and life hurts

     I don’t quite clearly remember all that I wrote in my blog post yesterday, and even the memory of the process of writing it has that slightly hazy feel of delirium, though I don’t think it literally applies.  Today I have to go to the office, because it is payroll day, and I’m already way behind on what I need to get done for that.  But I am still in a great deal of pain, even for me.

     I do remember deciding to indent my paragraphs by five spaces, as a kind of homage to the days of writing fiction‒though I used tab keys for that then, because I was using MS Word, not a smartphone.  I’m still indenting for this post.

     I’m getting on a very early train today so that I can get into the office in time to get some catch-up work done, and at a slow pace, because I still am in enough pain that my usual concentration is markedly diminished.  I don’t feel quite as delirious as I did yesterday‒I seem to have had some form of GI bug that made things worse‒but I’m far from my peak powers.  I still feel rather ill.  But I cannot simply take much time off.

     It’s oppressively hot and humid out.  Just standing still and waiting for the train caused me to be covered with sweat.  And then, getting on the train, I find the car is over-air conditioned, so it feels, at least for a moment, uncomfortably cool.  This is an interesting paradox of our climate control of our little, self-contained worlds: we control transient environments perhaps too much, and can never fully acclimate to the overarching external circumstances.  Admittedly, the weather being so hot and humid is quite uncomfortable, so I have a preference for some degree of climate control.  But it becomes a minor shock to the system when one leaves one environment for another.

     And, of course, the second law of thermodynamics (and the first) demands that the only way we can get it cooler inside is by putting more waste heat, and at higher entropy, into the outside world than we remove from the interior of, for instance, a train car.  No matter how efficient the system may be (and I doubt that it’s all that efficient) it cannot, in principle, be perfectly so.  This has been known for more than a century and a half.  Even the biological machinery that maintains a mammalian body within a narrow range of temperature, which is more efficient than any equivalent product of technology, still produces tremendous waste heat in highly disordered form, converting low-entropy energy into high entropy heat that cannot readily be used, eventually radiating into the surrounding cosmos, where it spreads out more with the expansion of spacetime, as all things head toward a predicted final fate of maximal entropy.

     Of course, on a universal scale, that process is going to take a very long time, so long that a human lifespan might as well be one of the fabled “virtual particles” of quantum field theory, popping into and out of existence before the universe can notice them‒though they can have effects.  I’ve written about this stuff before, I know, and won’t go into it again.  I’m sure if you searched either on this blog or on Iterations of Zero, you could find posts that discuss such things.

     As for me, I feel that my little, virtual existence is rapidly approaching its end.  Every day is painful, and that pain is not productive or useful; it certainly does not seem to make me stronger.  And, of course, I don’t really do anything for fun, I don’t do anything useful, I don’t make any arguable contribution that I can see.  I don’t think I’m even so much as a part of the quantum foam that has effects that can be felt in the reaction rates of elementary particles.  I’m just a virtual photon in intergalactic space.

     Though, I guess, I’ve had some effects already, since I have saved some lives and eased some suffering, and I’ve written several books and short stories, and most importantly, I have two wonderful children.  But my effects on them‒and certainly the impact of my fiction, and any past effects of my medical work‒are no longer happening. I hear from my daughter, but I have nothing of use to offer her, and I almost never hear from my son.

     I’m not doing much that has even a local, transient use anymore.  I certainly don’t think I’m having or sharing any insights or ideas that could honestly be useful to any of my readers.  And I no longer seem capable of making friends, nor of connecting with my prior friends, nor anything else along such lines.

     So, when I vanish back into the vacuum state of whatever quantum field I represent, there will be no real loss to anyone in the universe.  It would be nice to have family and friends around as one gets sicker and wastes away, but I don’t think I’ve earned any such thing.

     It is whatever it is, I guess.  I’m very tired, anyway.  And so much of what I am is pain, nowadays, without any counter-balancing joy.  At least I have done those bits of good in the past, for whatever they are worth.

     Anyway, I’m getting close to my stop.  I’m still a bit queasy, I’m sorry to say.  Or, well, I’m sorry to be able to say it truthfully.  It’s the fact, not the sharing of it, that troubles me.

     I hope you all have a good day, though.  Try not to air condition things too much‒it only serves to make the universe that much hotter that much sooner.  Ironically, so does heating things, by the way.

     Take care of yourselves and each other.  Spend time with your friends and families.  Be beneficent or at least neutral as much as you can.  And don’t worry too much.  In ten to the hundredth years, no one will remember all this, even in principle.

“People have this power–the numbers don’t decide”

It’s Saturday again, as I warned everyone would happen if we didn’t do something to stop it.  Unfortunately, no one appears to have listened, so, well…here we are again.

Of course, as I also warned you all, I am working today, and so, here I am writing another blog post, just like all the others.

Except it’s not quite exactly the same as all the others.  And, given the 1000 or so words per blog post, and the number of possible words there are available, even avoiding random jumbles of characters, the number of possible blog posts that I could write is probably far greater than the number of potential days I have left in any plausible human lifetime…or any plausible universal lifetime short of infinity, probably.

Let’s do some quick and dirty math.

I’m going to estimate very roughly, because I only have vague (but educated) intuitions, but let’s assume I start any given blog post with a choice from a list of maybe twenty words.  That seems like a decent ballpark figure.  After that, there are only a limited number of potential next words that would make any sense and that I might be inclined to use.  I’m going to cull that down to 10 options per each next word, and I’m going to ignore individual word probabilities and predominances relative to other words.  I’m also going to ignore the fact that I often write more than 1000 words per post.  We’re just being quick and dirty here.

So, with 20 first words, then ten to choose from for each next word, if we assumed more or less random sorting among those, we’d have a potential number of blog posts of roughly 20 x 10 to the 999th power, or 2 x 101000 possible blog posts.  That’s a staggering number of possible posts, each just a thousand words long.

How staggering is it?  Well, the famous number “googol”, is 10100 (ten to the hundredth power, or 10 times 10 times 10…repeated a hundred times).  It can be written as a 1 followed by 100 zeroes.  That number itself is roughly 10 to the 19th times as large as the number of baryons in the entire visible universe.  In other words, that’s ten billion billion times as many.  That’s more than a billion times the number of people alive on Earth now times the number of baryons in the universe.

But that’s just a googol.  A googol is so small compared to 2 x 101000 that if you subtracted a googol from 2 x 101000 the change would be so unnoticeably small that to notice it, one would require a precision far beyond the most precise measurement humans have ever made.  We’re talking about one part in about 10 to the 900th power.  That’s rounding off!

The best we’ve done as far as comparing experiment and theory goes is the magnetic moment of an electron‒or maybe it’s the fine structure constant, I’ll have to check on that (no, it’s the electron one).  That has been measured to agree with theory out to about the 12th decimal place, if I remember correctly.  As Feynman has said, that’s like measuring the distance between NYC and LA to the precision of the width of a human hair (which is far more precise than would in any case be useful or even applicable for such a distance measurement).

Anyway, the point I’m making is that the number of possible blog posts that can be a thousand words long with a few‒admittedly somewhat overgenerous‒constraints is staggering.  If I could write a blog post every Planck time for the rest of the life of the sun* I wouldn’t even make a dent, not a noticeable scratch or scuff in that number.  And you can’t really do more than one quantum event in any given Planck time, if I understand correctly, anyway.

So, I’m not going to run out of possible blog posts any time soon.  Even though I’ve probably overestimated the number of words I’m likely to use following any given previous word‒and I haven’t weighted the odds as would some GPT-like language model that creates text without thinking, based on huge numbers of things other people have written‒it’s still such a huge number that it’s too large really even to contemplate seriously.

And yet, time after weary time, I write blog posts about very similar things, such as my pain and my depression and the fact that I could really use some help from someone.  It’s very boring, I guess.  I apologize.  If you’re looking to diverge very much, I guess my blog might not be the ideal place for you.  But, of course, the huge majority of all possible blogs that would fit my above-listed criteria would be gibberish**, so we don’t want to get too caught up in those numbers.

It’s a bit like thinking about the human genome.  There are, I think, on the order of a billion base pairs in the human genome, and each “slot” has 4 potential nucleotide “letters” (adenine, guanine, cytosine, and thymine) so the number of possible genomes is about 4 to the billionth power, or 2 to the 2 billionth power…and every 210 is roughly 103 (210 being 1024),and 21000 is about 10300 so 2 to the billionth is about…1027,000,000, if my calculations are correct.  I’m not sure they are, but you get the idea.  It’s a big f*cking number!

Most of these orders of base pairs would not designate a human, nor even anything that could live at all.  So let’s whittle things down in truly draconian fashion and say only 10 to the 90th are potentially viable***.  That’s still far more potential humans than the number of baryons in the visible universe.

I think you can see that we’re never actually going to instantiate that number of humans, since each human is made of a substantial number of baryons…it’s something like 1027, but that’s just a ballpark figure****.  So, unless we find a way to generate a lot of new baryons, and fit them into the visible universe without causing the whole thing to collapse upon itself due to gravitational effects, the whole of actual humanity will always be a sea of unimaginably untapped potential.

I think we all kind of knew that, anyway, didn’t we?

Likewise, the number of actual blog posts I‒or anyone else‒will ever write before the heat death of the universe (assuming that’s the way things end) is embarrassingly negligible.  But we work with what we have.

And speaking of that, I guess I’d better mentally prepare myself for work, since I am already on the train.  I hope you all have a good weekend.  Whatever you do, it will probably be more interesting than anything I’m going to do.  Believe it or not, I find some consolation in that fact.

*It’s about 1060 Planck times:  1043 Planck times per second times 60 seconds per minute times 60 minutes per hour times 24 hours per day times 365.25 days per year times about 5 billion years.

**I mean even more so than my actual blog posts are.

***Don’t make the mistake of thinking that’s a reduction by 26,999,910/27,000,000. It’s way more of a reduction than that.  Don’t be fooled by the comparatively small numbers in exponents.  We’re taking a number that was 27 million digits long and making it only ninety digits long.  If you subtracted the second number from the first, it would be such a small change you’d have to look out well past the 26 millionth digit even to see a difference.

****Again, don’t be confused by the relative closeness of the exponents and worry that we’ll run out of baryons soon.  10 to the 27th is vanishingly small compared to 10 to the 81st.  In fact, curiously, 1027 x 1027 x 1027 = 1081.  Every single gram of hydrogen contains 6 x 1022 atoms, and obviously the number of grams of hydrogen in the universe is waaaaaaaaaaaaaay bigger than that!

Nor can I fortune to brief minutes tell, blogging to each his thunder, rain and wind

Hello and good morning.

I decided yesterday afternoon that I would try to write something a bit different for today’s post, rather than just another litany of my depression and despair, since I’m sure any dedicated readers are probably getting almost as tired of reading them as I am of experiencing them.  I cannot directly alter the fact that I experience them—if I could, I would—but I don’t have to make it an uninterrupted trail of goo for you all to slog through on a daily basis.

I came up with two, more or less unrelated, ideas, but I’m only going to focus on the first, which is nearer and dearer to my heart and mind, in any case.  It’s also been something I’ve thought about on and off for some time.  I do wonder what pertinent quote from Shakespeare I’ll find to alter to make the title, but of course, you who are reading will already know the answer.

Don’t spoil it for me, okay?  I want to be surprised.

Anyway, the idea I wanted to bounce around today has to do with the question of the discontinuity of reality at a mathematical level.

I’m sure many of you are aware that, from the perspective of quantum mechanics, there is no sensible differentiation in, for instance, location at any scale smaller than the Planck length, which is about 1.6 x 10-35 meters, or in time below the Planck time, which is roughly 10-43 seconds.

There are various reasons for this, and I won’t try to get into them, but this is generally agreed upon by all the scientists who work in the field.  It’s part of why there is an upper limit to the number of possible quantum states within any given region of spacetime, defined, thanks to Bekenstein and Hawking, as the surface area of an event horizon surrounding that region as measured in units of square Planck length.

Thus, based on the best current understanding of the micro-world, the universe is not so much pixelated as blurry at the smallest scales.  Admittedly, these are very small scales—far smaller than we can probe currently, so we may, in principle, be wrong about some of it, and quantum gravity might change our understanding, but there are strong reasons for this assessment.

Now, mathematics—thanks to work threshed out by Newton and Leibniz, building on ground first broken (though no one quite realized it at the time) by Archimedes about two millennia earlier*—can deal with things that are truly continuously divisible.

Those of you who took high school level calculus (or higher) probably recall that a derivative involves finding the instantaneous slope, or rate of change, of a curve describing some function, such as the instantaneous acceleration being the rate of change of the “speed”.  The idea of it had to do with taking the slope of a line connecting any two nearby points on the curve and bringing them closer and closer together, taking the limit as that distance goes toward zero.

Analogously, integrating a function involves finding the area under a curve, and is in a way the opposite of a derivative.  This involves splitting the area under the curve into rectangles of fixed width at any given point along the curve (the height defined by the value of the curve at that point) and adding them together, then taking the width between the points to be smaller and smaller, until one approaches the limit of an infinite sum of “infinitesimally” narrow rectangles.

These processes are tremendously useful, and can describe the orbits of astronomical objects and the trajectories of ballistic materials, just to take two simple examples.  They are good for describing the universe in many ways, and they often produce useful and accurate answers and predictions to the best of anyone’s ability to measure.

But that raises my question.  Do we currently have the capacity to tell the difference between processes in the universe—say, for instance, acceleration due to gravity—being truly continuous or them being in a sense discontinuous?

We know that the Real Numbers are uncountably infinite, as a matter of pure mathematics.  Between any two nonidentical real numbers, however arbitrarily close together, exists an uncountably infinite number of more real numbers, as large—so to speak—as the number of real numbers themselves, a Russian doll in which every new doll revealed by opening the previous one has just as many dolls inside it as there were inside the original Russian doll…but even more unlimited than that.

This is, however, not necessarily relevant to reality**.  Just to demonstrate that fact:  we can calculate Pi (π), the ratio of the circumference of a circle to its diameter, to any number of decimal points we might choose, but it will never come to an end—it’s an infinite, non-repeating decimal number, one of the “transcendental” numbers.  Pi has been calculated to 62.8 trillion digits (as of 2021) but that’s not a number we could ever measure as the ratio of the circumference of any actual circle to its diameter.

I’ve read (from a reliable source) that only 39 digits of Pi are necessary to calculate the circumference of the visible universe*** to the fineness of a single hydrogen atom.  Now, a hydrogen atom is about 1033 Planck lengths across, according to a quick search, so that means, in principle, we’d only need Pi to 72 digits or so to calculate the diameter of the universe to the nearest Planck length.  That’s a fairly large number of digits, but it’s smaller than the order of magnitude of, for instance, the estimated number of baryons in the visible universe, and is smaller than the entropy “contained” in even a solar mass black hole****, unless I’m seriously misremembering.

So, finally, my question is, how well have mathematicians ascertained that aspects of reality can in truth be described by equations that are actually continuously variable, or whether we could ever tell the difference?

A computer, for instance, could simulate some model of a continuously varying system to a high degree of precision by taking each current state and then applying an approximation of the applicable equations to the next state, iterating each step in sequence, as if recapitulating the steps that led to the limit defining the derivative or the integral of a function.  This would be considered an approximation of the true function, of course, but one could, in principle, get arbitrarily close to the true function by taking one’s intervals to be arbitrarily small—solving, for instance, or at least simulating, the three (or more) body gravitational problem, by calculating, at each instant, the net effect of each object on all the others, calculating the acceleration, applying it, moving each thing a tiny step, then recalculating.

But what if it’s not the step-wise approach that’s the approximation?  What if the continuously differentiable functions we use to describe things like gravity and electromagnetism and the various quantum mechanical matters are the approximations?  What if reality is more Δx/Δt than dx/dt?

Obviously this is a simple enough concept to come up with, and I’m far from the first one to think of it.

My more immediate question is, has anyone demonstrated mathematically just how fine our measurements would have to be to tell whether, for instance, the orbit of a planet around a star follow a truly continuously differentiable path, or if it is just a step-wise, iterated process?  If one were able, for instance, to simulate the orbit of a planet, say, by iterating an approximation each Planck time, and reconfiguring the system at each step to the nearest Planck length, how long, in principle, would it take to be able to tell the difference between that simulation and a truly continuously differentiable motion?  Could there, given the constraints upon the nature of reality applied by our best understanding of quantum mechanics and the like, ever be any measurable difference?

I don’t know if this has been addressed by mathematicians.  It may not have any practical implications, since we’re a long way from being able to measure reality precisely enough—or so I suspect—to tell that difference.  But I wonder if it’s been worked out just how finely we would need to be able to measure to tell if reality is truly continuously differentiable.

If anyone reading is a mathematician familiar enough with this sort of question to give me an answer, I would love to hear it.  Or if you know a mathematician with appropriate expertise, or a physicist of similar expertise, I would dearly like to know if anyone has done any explorations from the mathematical (not simply the practical) point of view regarding this.

That’s it, that’s my subject for the day.  I feel that I’ve been very ham handed and brutally quick in the way I’ve gotten into the subject, and for that, I apologize.  I only have the time to write this between my shower and when I leave to go to the train station, so it’s a bit quick and dirty, as they say.

Obviously, I don’t have time or space today to address my other, unrelated question, which is about whether the legality and ubiquity of large-jackpot lotteries of various kinds has changed the general psychology of, for instance, the American people in a way that has decreased “average” ambition and work ethic, providing “bread and circuses” to the masses in a way that has at least contributed to the greater economic disparity between socio-economic levels in the nation (and the world) and the gradual dissolution of the middle class?

I wouldn’t dream of thinking it the only or even the dispositive factor, but I wonder if it might have contributed.

Maybe I’ll write about that tomorrow.  Weirdly enough, we may have a harder time coming up with definitive answers for that question than the one I tried to discuss today.  Mathematics and physics are easy, in a sense.  Biology, psychology, sociology, economics…these things are truly hard to model and describe in useful, predictive ways, because the systems are so complex, with so many variables, both dependent and independent.  Even weather, the quintessentially chaotic system, may be more tractable.

I hope this has been more interesting than my usual reflections and projections of gloom.  I also hope you all have a very good day, and maybe that you think a bit about what I’ve written.

*What a Mary-Sue that guy was!  I mean, forget the whole acrimonious debate on priority between Newton and Leibniz regarding calculus, these guys were about two thousand years behind the Eureka Man!

**Though it could be, even if distance and time and not limitlessly divisible.  For instance, if the Everettian “Many Worlds” description of quantum mechanics is correct, the overall “space” of “universes” created at points of decoherence/branching could be infinitely and continuously divisible, making it a no-brainer as to how many potentially different worlds there might be in that space—not “real” space, but the orthogonal space that contains all the branches of the many worlds.  However, that might not be infinitely divisible, either.

***That’s everything that can, even in principle, be seen given the finite time light has had to reach us since the Big Bang.

****The Entropy is about 1077, but Entropy is proportional to the natural log (basically, taking a log is the opposite of raising something to a power) of the number of possible microstates in a system, so that number of states is e to the 1077 power, or e multiplied by itself 100000000000000000000000000000000000000000000000000000000000000000000000000000 times.

It’s the end of the week as I know it, and I feel…

It’s Friday.  This week, that means that I have the next two days off work.  I wish I had something fun to do tomorrow or Sunday, but really, my only goal is getting my laundry done on Sunday morning and trying to get a little bit of extra sleep if I can.

I don’t have any friends with whom to do anything fun, and I don’t want to try to achieve anything interesting or useful with anyone.  And if someone were to surprise me with anything other than, for instance, a trip to some kind of inpatient psychiatric facility (pre-paid), I would not be terribly happy about it, though I guess if it were someone I haven’t seen in a long time I might be happy, depending on who the person is.  But that’s not going to happen, anyway.  Actually, neither of those things is going to happen.  As far as I can see, I’m just going to continue as before.

I guess it’s somewhat noteworthy that this is the last day of June in 2023.  Tomorrow begins a new month, the month of Julius Caesar, huzzah (If June had 31 days, then July would begin on Sunday, and we would have a Friday the 13th in July, but alas, this is not to be).  Rent and power and water and other bills are all coming due.  I don’t really care about all that.  It’s not like I have anything else to do with my money, other than get new Kindle books or what have you.

Even that’s getting harder as time passes.  There just aren’t really any new books in which I’m interested.  I still can’t seem to read any new fiction—or old fiction for that matter, not even my old favorites.  There are no shows I want to watch, and no shows that I really want to rewatch, and very few movies.

I suppose I wouldn’t mind seeing The Guardians of the Galaxy 3, but I don’t want to tempt myself with movie theater popcorn and whatnot.  Going to the movies and not getting popcorn and maybe Goobers and such would just feel terribly sad, quite apart from going alone.  Anyway, I’m trying to avoid such foods.  They tend to make my overall energy and health feel worse, and that’s not something I need, obviously.

I rather wish I had been familiar with Uber and Lyft on that first weekend, when I was considering going to the theater to see GotG, and before I had made my current dietary changes.  At that time, I meant to ride my bike there.  However, I had increasing trouble with my back when using my bike, and then the front tire went flat and everything, and now it’s just sitting there upside down under the overhang, a little way outside my door.  It was yet another waste of money and time and effort.  And it’s too far to walk to any theater to see the movie without arriving sweaty and gross—and, again, right now I’m avoiding movie theater type foods.

I was thinking of walking to the train this morning, but I’m really not up to it.  I’m getting a better handle on shoes for walking—or, technically, boots in this case—at least, and I now have three pairs of identical black lightweight hiking boots, which are good for the ankle support and for the general feeling of having my feet in armor.

But walking is a bit unpleasant just because it’s so very hot and humid right now in south Florida.  This probably comes as no surprise to anyone out there.

I regret coming to Florida, to be honest, though I think the state is quite beautiful, physically, in a great many ways.  I like all the plants and the reptiles and birds and amphibians, and even some of the arthropods (I like spiders, and dragonflies are also very nifty).  But most of the worst things that have happened in my entire life have happened since I’ve come here.

Not to say that there aren’t compensations, of course.  My daughter was born in Florida, and I wouldn’t change her existence or nature for anything.  But it would have been nice, once she was born, to have gone back north.  Imagine if my kids had been able to be in White Plains (where I lived before moving to Florida) and so had been able to go to one of the best public school systems around.

Actually, they’ve both done quite well with respect to their education, as they desire it, and maybe the added pressure of being in a more competitive system would have been unpleasant.  I don’t know.

Anyway, the past is done, so it’s pointless to dwell on changes to it.  And I cannot change the present, obviously, since it’s actually already happened/happening in each given moment.  And the best anyone can do is try to steer toward preferred futures, but it may be, as a matter of physical law, that the future is set and inevitable and/or partially random and unpredictable.

As far as the experience of limited minds and beings such as we are, though, the future feels like something over which we have at least some degree of control, or at least through which we have some ability to steer.  It’s limited steering, of course.  It’s not as if we were in a car and driving; it’s not even as though we’re in a sailboat with a rudder.  It’s more as if we’re surfing, and if we do it as skillfully as we can, we might be able to surf in the direction we more or less would prefer to go.

Me, I think those reefs up ahead look inviting.  There are lots of sharks in the surrounding waters, too.  It would at least be a bit exciting, though perhaps painful and frightening at the time, to go there.  Then again, there’s also that whirlpool over yonder; that might be interesting, too, and probably a bit quicker.

I’m not much of a surfer, however, even metaphorically (non-metaphorically, I’m not a surfer at all).  I don’t think I’m surfing on the chaos of reality anymore, anyway, and I don’t think I have been for a long time.  I think I’m just treading water.  And it’s not as though I can just build myself a surf board, or a raft, or a boat or a ship, or anything else, out of the water in which I’m floundering.  And there are no vessels on the (admittedly quite limited*) horizon (though I do keep trying to send up flares).  So, I’m kind of just stuck here, treading away, until I finally tire out and go under.  I don’t know what else to do, but I’m already terribly fatigued.  I guess it’s “good” that the ocean water is salty**, or else it would be harder work to stay afloat.  Or maybe it would be better if it weren’t, so I could tire out more quickly and just have everything done.

Anyway, that’s enough of all that.  I’m sorry, it’s not an interesting blog post.  I think I’ll head out now.  Maybe I’ll get an Uber or Lyft to the train station.  I feel too lazy even for the bus.  We’ll see.

Have a good weekend, please, if you’re able.  If you’re with friends and family, for goodness sake, don’t take them for granted.  Not that you probably do.  Anyway, thanks for reading.

*I say this because, if one were treading water, one’s head would only be a foot or so above sea level, and so the horizon is very short, being a function of the height above the surface and the radius of the Earth.  Thus, as your height above the surface goes to infinity, your horizon asymptotically approaches half of the planet, though of course you would be having trouble with the limits of angular resolution and the amount of light dropping off as the distance squared and so on.  If the Earth were flat—which it is not—the horizon, even from a foot above the ocean, would be indefinitely large, limited only by structures that got in the way, and any haziness that attenuates light.  If the Earth were flat, then from the top of Mount Everest, with a good enough telescope, you could see everywhere on the planet.  You can’t, of course.  The world is round.  This has been understood for thousands of years, contrary to popular conceptions about the ignorance of people in the past.  Eratosthenes knew it 2200 years ago, and even used clever geometry to measure the Earth’s circumference, to within a few percent of the modern best measurement.

**Oh, by the way, did you see the recent reports about the shifting of Earth’s axis (a very small one, but real and measurable) that’s been caused by redistribution both from melting of glaciers and from the extensive pumping of ground water and the redistribution of that and the glacier water into the ocean?  It’s interesting that I was just talking about the changing angular momentum of the Earth by such things shortly before that report came out.  It makes me feel almost clever, though I did have a bit of a self-deprecating (though far from unhappy) head-slap moment when they mentioned the changes due to depletion and redistribution of ground water.  That had not occurred to me.  It’s always nice to have new facts and notions pointed out that make such sense.

“And everything under the sun is in tune, but…”

It’s Wednesday, June 21, 2023 (AD or CE, as you prefer), and I’m writing this on my laptop, but it’s not on my lap.  It’s resting on my desktop at the office, because I stayed here overnight last night.  I had a bad day—personally, not professionally—at the office, yesterday.  I felt just rotten, partly due to how poor a sleep I had, even for me, the night before.

I considered leaving early, but we were rather busy, and I didn’t feel I could justify cutting out on everyone.  Also, I had the nagging concern that, if I left early, I might never come back, because I really felt at my wits end, and though I had no specific plan in mind, I thought I might take some kind of drastic action to make it impossible for me ever to do anything again.  I just wanted to go to sleep and to sleep and to sleep and perhaps never to wake up.

Anyway, it really started to thunderstorm rather badly near the end of the work day, so I decided I would just stay at the office.  I’ve had a hard time getting up to my usual status on the payroll this week so far, and it has to be finished by today, so eliminating the commute time will better allow me to finish that.

But everything is getting too onerous for me.  I’m so tired, and I have no internal drive or purpose of significance, just habit and stubbornness, which can’t really ever make up for the real thing in the long run.  I don’t know what I’m going to do.  I need help, but I doubt I’ll get any, and I don’t think I’m capable of seeking it.

I can’t make myself believe that I deserve or am worthy of any help.

Speaking of long runs (I was, you can go back and check) today is the Solstice—the summer one in the northern hemisphere, and the winter one in the southern hemisphere.  Thus, it is the “longest” or the “shortest” day of the year, depending on one’s location.  I use scare quotes because it’s not the actual length of the day that varies on this date, or from day to day in any kind of steady way, but the duration of daylight, the time in which the sun is overhead, or at least visible in the sky (barring clouds).

But, of course, the length of a day really does change a bit from time to time, though not in anything like as regular, nor as dramatic, a fashion as daylight does regarding solstices and equinoxes and all that.  The earth is a rotating mass, and is subject to the laws of angular momentum.  Thus, when enough mass changes position on the surface of the planet, it can have an effect on the overall rate of rotation of the planet.

The stereotypical “demonstration” of this process is a skater spinning on the ice, who speeds up when bringing his or her arms close to the body and slows down when extending them.  This is because, crudely, the angular momentum is mvr, the mass times the “tangential” velocity (of the mass), i.e. the speed at which it goes around the center of rotation, times the distance from the center of rotation.  Thus, since angular momentum is conserved, if the radius shortens, the velocity around the center of rotation increases proportionately, and vice versa.

The instantiation of this is somewhat complex, as is usually the case, but this really is the gist of it.  The conservation of angular momentum is related to the rotational symmetry of the universe, as per Noether’s Theorem—i.e., the laws of physics aren’t dependent upon which direction you happen to be facing.  This is similar to how conservation of linear momentum is related to symmetry of translation—i.e., the laws of physics don’t depend upon where you happen to be along any linear direction.  And conservation of energy (locally) has to do with the symmetry of time.  This last one can be tricky when taking the universe as a whole, because conservation of energy doesn’t necessarily apply to the whole cosmos, nor is time fully symmetrical on the largest of scales, or so it seems, but locally it is true.

Physicists, please correct me if I made any gross errors there.

Anyway, back to the rotation of the Earth and the length of days.  Movement of significant amounts of mass on the surface of the planet (or within the planet) can change the rate of rotation of the planet.  I’m led to understand by the program QI* that a massive hydroelectric project in China cause the “elevation” of a large enough mass of water to slow the rotation of the Earth by a measurable—if inconsequential and utterly unnoticeable—amount.

I sometimes wonder if the periodic gathering of millions of people near the mouth of the Ganges has any potentially measurable effect on the momentary rate of the Earth’s rotation.  I’m not aware of anyone having made such a measurement.  Even if it’s true that it changes the rotation rate, it may be too small to detect.

I also wonder whether, as glaciers on mountains and across Greenland and similar melt, with the water thus previously elevated seeking a level closer to the center of the Earth, the planet’s rotation might well speed up.  I wouldn’t expect glacier melt in Antarctica to speed up the rotation in quite the same way, because those glaciers are all far closer to the axis of rotation in the first place, and so might have limited effect in shortening the “lever arm” of rotation.  Indeed, if they raise sea levels significantly enough, I could imagine the “center of mass” of the Earth’s rotation moving slightly outward, especially as the seas bulge more at the equator, thus slowing the motion of the planet down.

The odds of this perfectly balancing seem small, but I imagine it would require very complex calculations and—more importantly—quite fine measurement to ascertain the net balance.  And, of course, the balance is likely to shift over time.

In comparison, it’s relatively** easy to calculate the balance between special and general relativity required to keep GPS satellites in synchrony with the ground.  In this case, the speed of the motion of the GPS satellites slows down their local passage of time relative to the surface of the Earth, by a calculable and quite constant amount, but their greater distance from the center of the “gravity well” makes their time go faster relative to the surface of the Earth, again in a quite calculable and rather constant rate.

It’s the latter effect that predominates, and this is routinely accounted for in the GPS process.  If it were not, GPS would have huge and increasing errors as the timing in the satellites and of ground-based clocks diverged steadily, and the errors would very rapidly become far too great to be useful.  So, your use of smartphones to find where you are and how to get where you’re going depend on both of Einstein’s theories of relativity.

I guess you all already knew all that.  Sorry to be boring.

Anyway, that’s my bit*** of trivia for the day.  It will probably be the most interesting thing to happen to me in this particular Earthy rotation, but I hope all of you are having more interesting days than I am.  I’m just very tired, and discouraged, and worn out…and it’s only a little after five in the morning.

I’ve been in pain for twenty years, and I haven’t seen my kids (in person) nor interacted with my son at all (barring one email) in over ten years, and my last remembered restful night’s sleep happened in the mid-1990s.

If I could just find way to get restful nights’ sleeps, that would be a start.  Everything else would be easier, or so I suspect, if I could find a way to make that happen.  Then again, perhaps it wouldn’t help, and I would simply be faced with the tragic irony of having that wish come true only to find that it didn’t make the other things better, and might even make them worse.

Never underestimate the potential for things to get worse.  Reality has no bottom.

There’s that symmetry of translation that implies, by Noether’s Theorem, that momentum will be conserved.  Which brings me full circle, thus recapitulating the conservation of momentum/symmetry of rotation.  It’s neat, isn’t it?  Time, however, is a trickier bit of possible symmetry, as Pink Floyd recognized only too well.  But at least after Time has passed, when on The Dark Side of the Moon, one can look forward to the beauty of The Great Gig in the Sky.

If you haven’t listened to that album in a while, why not listen to it today?  Or if you’ve never listened to it, treat yourself.  It’s well worth it.  What the hell, it’s the longest day (or night) of the year.  Indulge yourself.  And if the cloudbursts thunder in your ear—you shout and no one seems to hear—and if the band you’re in starts playing different tunes, I’ll see you on the dark side of the moon.

Blog Post for June 20, 2023 (AD) – Tuesday

It’s Tuesday morning, and I’m beginning this post at the train station rather than on the train, because this time I timed things so that I arrived a few minutes after the 6:10 train passed.  That way, I didn’t feel the urge to chase after it, like what I described the other day.

This was somewhat deliberate, but it also had a lot to do with just how tired I already am.  I don’t talk about my insomnia all that often, probably for the same reason most of you don’t talk about breathing very often.  It’s just always there.  But last night was worse than many; starting at a bit before two, I “woke up” every five to ten minutes, looking up at the clock, as if I were worried that I might have overslept.  I don’t know what I’m worried about in such situations, honestly‒it’s not as though there would be any objective, dire consequences if I were late.  But, of course, the real problem is that I would be distressed and upset if I were to miss my schedule.  And because of that, I can’t seem to sleep.

So, this morning, I already feel fatigued and mentally worn down, and the day is just getting started.  Of course, yesterday by noon or so I was already mentally crashing at the office, and that was Monday after a full, two-day weekend!  The crash was acutely due to my usual frustration with the nominal rules of the way we do things in the office being ignored when convenient in the short term, but it’s really all a cumulative and complex process.  By the end of each day I’m worn down more than I was at the beginning, and by the next morning I haven’t really gotten quite back up to the level I was at the start of the previous day, perhaps partly due to my insomnia.

It’s not a precise, smooth curve, of course; there are day to day fluctuations, and even I am not always in my worst state of mind.  But overall, the trend is downward, and I think it’s fair to say that I am now palpably lower than I have been in a very long time, if not ever.

It’s a good thing that I can at least talk to my sister on the phone for an hour or so once a week.  But I’m so annoyingly stressed by social interactions that, even with my sister‒whom I’ve literally known all my life, and with whom I get along as well as pretty much anyone‒I have to schedule and plan the phone conversations ahead of time, and generally on weekend days when I’ve at least had a mental break.

It’s ridiculous and pathetic, I know.  I can’t give it any kind of noble or even sympathetic spin.  I’m disgusted by myself…but then, that’s my general attitude toward myself, anyway.  Not to say that there’s nothing about myself that I like, of course.  I like that I’m very curious, and that I can understand science and math and all that stuff rather well, and that I have a good memory, and that I can learn things well and more easily than many other people seem to be able to do.

Even when very depressed and moriphilious* I’ll find myself inescapably driven toward ordering‒or at least to consider ordering‒some book or audio book, perhaps by someone I’ve heard speaking on a science and/or philosophy podcast, or similar.  Also, as I think I mentioned yesterday that I was considering, I did order the hardcover copy of Quantum Field Theory as Simply as Possible.  I almost ordered the author’s textbook (especially when I saw that, among many other places, Cornell uses it), but I decided I would start with the bird’s eye view before going deeper, partly because I’m not sure I have the mathematics expertise really to grasp the deeper stuff in a strict fashion.

I may.  I’m pretty good at stuff like that, and I can build on my prior understanding with more ease than some can, because I don’t tend to learn things by rote.  I learn by a sort of model-building in my head, which means it can take me longer to prepare for a test, for instance, but once I understand something, I don’t tend to lose that understanding very quickly, and can apply it elsewhere and merge it with other matters.  So, if I can get the concepts of some physical theory, and the concepts of the pertinent mathematics, then the nitty-gritty, nuts and bolts of it is much easier then to master.  That’s nice.  I do like that about myself.

But I don’t really have anyone around with whom to talk about the things in which I’m interested at any very deep level.  And it’s hard to contemplate even seeking out such people.  I would be stressed out worrying that dealing with other, new, and potentially frustrating people would be too much effort, but also‒perhaps more so‒that I myself am an irritating person, and I can’t quite bring myself readily to inflict myself on other people.

Also, I would probably have to go through some online community‒perhaps some form of “discord” or whatever that app/system is, or some Facebook or Twitter group or some** such.  I’ve never been interested in trying to get into Reddit communities, and most of the other social media meetup type things are anathema to me.  I don’t even like gaming with strangers online.

Early on, back in the day, I got on a Yahoo! based depression support chat group, but mostly I just lurked, though I did make a very good online friend in one, who (among other things) introduced me to both Sailor Moon and Radiohead, so that was a tremendously lucky and great meeting.  I cannot thank that person enough, and we are still in occasional contact to this day.

But even things like that Yahoo! group have changed and no longer appeal to me.  And I have changed since then, too, of course.  I’ve been to prison, for one thing.  That’ll change you a bit.  Probably even a cushy minimum security Federal Prison changes people, and FSP West is most assuredly not such a place.

Anyway, enough nonsense for today.  Tomorrow is the Summer/Winter Solstice, for what it’s worth, so I’ll probably mention it then, unless I’m lucky enough to have something happen that makes me unable to write my blog post or anything else.  Or unless someone swoops in and rescues me from the verge of the event horizon.

That’s not gonna happen, is it?

Oh, well.  Have a good day.
