“Sleep”, writing, and studying physics–report for June 5, 2024 AD/CE

Well, I got almost 4 hours of uninterrupted sleep last night, plus 20 minutes or so of on and off dozing.  While that sucks big-time, it’s better than it’s been lately.  At least I’m not seeing bugs on the walls out the corners of my eyes right now–though I still keep briefly thinking there’s a cat waiting by any door that I open, until I look down and see that there isn’t.

What can you do?  Not much right now, it seems.

Anyway, I produced a decent amount of work this morning.  I wrote 1,373 “block” words and 1,388 “net” words, with a difference then of just barely over 1% no matter which number you take as your denominator.  The total word count of this would-be short story is now 54,327 words, and it is 83 pages long in the format I described yesterday (I think).  It’s definitely more of a novella.

I’ve been doing a bit of reading these last few days, skipping between Sean Carroll’s two Biggest Ideas in the Universe books and the first volume of Feynman’s lectures and Jordan Ellenberg’s Shape*.  As you know, I’ve been trying to teach myself more of the physics on which I missed out by switching majors after my heart surgery, especially General Relativity and Quantum Mechanics/Quantum Field Theory.  Sean Carroll’s** “Biggest Ideas” books are focused on explaining those things for interested laypersons without avoiding the mathematics, but not practicing teaching/practicing how to do the math, so it’s a good beginning.  Of course, in a perfect world, I intend to beyond the overviews and actually to get comfortable with using the mathematics, particularly because I want to understand the cosmological constant at the level of the mathematics of General Relativity, because that’s the only part that I don’t quite get intuitively.  But really, I want to understand and be able to use all of it, and to be able to read all the papers on arXiv and understand them at the level of a professional, like I can with medrXiv and bioRxiv.

I doubt that I will live that long.  But, in the meantime, at least I’m learning new things.

Tomorrow is Thursday, so of course, I will be doing my more standard Thursday blog.  It’s silly to call it a “weekly” blog, since I’ve been writing these reports almost every day; once I’ve started a habit it’s hard for me to deviate from it.  But I don’t plan to write any fiction tomorrow, but instead will just focus on the blog post.  I’ll see you then (so to speak).

*I’ve not yet encountered a better teacher of mathematics than Professor Ellenberg.  He captures and conveys the fun and beauty of math as well as anyone I’ve encountered and better than the vast majority.  He narrates his own audio book versions, too.  If you want to review general mathematical ideas and then general geometric ideas (and their surprising applications) in an accessible and enjoyable way, you could not do much better than reading (and/or listening to) his books.

**Professor Carroll is another great teacher, though he deals with slightly more high-falutin’ stuff than Professor Ellenberg in his books, so the subject matter can be denser.

My thoughts are minutes; and with sighs they blog their watches on unto mine eyes

Hello and good morning.

It’s Thursday again—indeed, it is the last Thursday in May of 2024, common era, and this day will never come again.  That is, it will not come again unless time turns out to be cyclical, in which case, I guess this day will come again over and over, an infinite number of times, though it would never feel that way from inside.

Certainly, in at least some sense, this day is permanent.  For instance, this is so if, based on Special and General Relativity, one can consider the universe to be a “block universe”, i.e., one in which each event and moment or whatever you want to call it in all of space and time is simply what it is and is “always” there, like a cosmic Blu-ray® that plays itself.  Except it doesn’t play itself.  Again, it simply is, and the sense of time passing is simply something experienced by tiny beings that comprise little four-dimensional braids of energy because of the way they are put together or rather the way they exist in local spacetime.

I’ve written about this before, considering the question, if we (and everything else) are permanent and unchanging local patterns in spacetime from the beginnings of our lives to the ends, might it be that, when we die, from an experiential point of view, we merely start over at the beginning, with everything in our lives happening over and over.  Or perhaps it’s more accurate to think that, in such a case, there is still a “me” that is living yesterday, experiencing it, and the day before and the year before and the decade before, and so on, in a possibly infinite continuum of moments.

If that were to be the case, then the best general advice would probably be to try to make your life such that, if you are going to live it over and over again for eternity, that will not be the equivalent to being condemned to Hell.  I think Nietzsche talked about something like this, but I may be misremembering.

Of course, each time one lives one’s life again is restarted from a local blank slate.  It’s not as though you would ever have any memory of having gone through all this before, any more than a character in a movie learns from the fact that you’ve played the movie before and behaves differently next time.  Anakin Skywalker will never avoid becoming Darth Vader, no matter how much we see that he suffered horribly and did horrific things that he regretted, all while failing to achieve what he had meant to achieve by going to the dark side in the first place.

So, however you were going to live your life is how you were going to live your life—from the outside perspective—and you should just try to do the best you can in any case, because…well, why would you do anything else?

Of course, whatever you end up doing is literally doing the best you can, since you cannot change what you do once it’s done.  See above regarding the permanence of time and so on.  Even if quantum mechanics in some way derails the “simple” spacetime block notion*, that doesn’t make the past any more amenable to adjustment.

Whatever the nature of reality ultimately is, it is, and we are not going to change that.  We can learn more and more about it and use that knowledge to our benefit, but we cannot ever escape whatever the meta-level rules of reality are, any more than a pawn can make any legal move that allows it then to change the rules of the game of chess.

Anyway, that was all good fun and we all had a jolly good laugh, but I feel that perhaps I’ve trodden such areas too often, and I’m probably boring my readers.  Apologies.

Junes is coming in two days, and it’s a relatively eventful month.  A close family member of mine has an important birthday; the Solstice will be here (Summer in the north, Winter in the south); and of course, Father’s Day comes in June.  That’s a bitter holiday for me, unfortunately, but there’s nothing I can do to change that preexisting fact; again, see above.

As for other things, well, I think I got a slightly better sleep last night than I’ve been getting lately.  I still began waking up at about 1:30 in the morning, but I was able to go back to sleep again until a little after 2 and then about 2:30 or so, and 3, and then started just giving up and fully waking up at about 3:20.  Even so, at least I was able to get to sleep somewhat earlier than I usually do, and that’s saying a lot.  It may be quite tragic that three and a half hours of uninterrupted sleep feels so much better than usual, but it does.

It’s not simply happening randomly, just to be clear.  I am making interventions and trials and seeing what helps and what doesn’t.  I’m not going to get into them for the moment, lest I cloud my own mind with the discussion.  But it’s not just that, hey, wow, I’m sleeping slightly better these last two nights, gosh I wish I knew why.  It’s the product of my always ongoing attempts to improve things when I can.

I’ve also been reading a bit for that past few days on and off—mainly Sean Carroll’s new book—but, while this is a good thing, it’s not an unadulterated good.  I won’t get into the reasons for that caveat, and in any case, from my perspective, it’s overall a positive.

Tomorrow I’ll go back to writing my one page (or possibly more) on Extra Body, and I will give a brief report on that (probably), though my brief reports are somewhat prone to digression into not-so-brief discussions of tangentially related subjects.  I am also going to be working Saturday, barring any changes, so I’ll probably rinse and repeat then.

In the meantime, I hope you all have a great rest of the week as May draws to an end and June arrives.

*It need not do so.  The spacetime block might merely be more complex than our first, naïve notion of it, and actually be a spacetime block made of the universal wavefunction, with “branches” at every quantum decoherence and a level of splitting that may be as fine as the divisions of the real numbers, uncountably infinite.  Taken as a whole, though, these could all still be fixed and “permanent”; there would just be more of a fractal sort of character to it at the level of quantum interactions and the like.

Numbers of words and words of thoughts and thoughts of consciousnesses

Since I came up with the idea and mentioned it in my blog on Saturday, I could not fail to put the idea into practice of keeping count of both the number of words in the new “block” of fiction writing I did today and to keep track of the change in the total word count, to compare them.  This was especially true since, on rereading what I had written on Saturday, I realized that I had started a conversation between two characters rather abruptly, and so I added in a more natural beginning to that interaction while I was editing.

This didn’t have as big an impact as it might have, since I also pruned things slightly while rereading.  In any case, I kept track of the net total word change and the word count in the new block of writing, and those numbers are:  1,228 words in the new block written today, but a net increase in word count of 1,264.

I don’t know how representative this is of the typical disparity, but it’s less than a 3% difference whether you use the larger or the smaller number as your denominator, so it’s not huge.  Still, I’ll probably keep this up, at least for a while.

After I had finished writing and gotten up to get ready to get off the train, I had a weird train (ha ha) of thought that led from me thinking about the fact that one can no longer readily stream series A through I of the British show QI in the US, to how I had needed to order the DVDs for those seasons through Amazon UK, which I did quite some time ago.  This led me to think about the shipping process, and how seamless and rapid it had been–it was not as fast as ordering something that’s sourced locally, but nevertheless it was impressively rapid.

And I thought of the various people involved, and how not one of them had been aware of the whole process from beginning to end, and indeed, possibly not one of them had thought about what was being sent and to where.  Each part of the process was more or less automated, or at least occurred “locally”, in a phase-space sense*.  And yet, the whole has become a process that takes place with remarkable efficiency, despite no member of the chain of the process really knowing too much beyond their own part of the job.

And I thought, the whole economy is like this, locally, nationally, and globally.  Indeed, all of civilization is like this; everyone simply acts in response to local forces and events and incentives and disincentives, and the process turns into a self-sustained, much larger entity that has not been created by anyone, and is certainly not run by anyone (any more than a bee hive or an ant hill is “run” by the queen insect).  Nor should it be, since no human mind is capable even of grasping very precisely and in detail anything beyond a tiny part of the thing itself–this is probably part of why “planned economies” always fail, and until there is a super-intelligent AI (and perhaps even then) they always will.  It’s like trying to put one single nerve cell in charge of the entire human brain and body.  It simply doesn’t have the capacity to do such a thing.  When one nerve cell’s activity spreads with relatively little impediment through the brain, you get what we call a seizure.

Anyway, all that led me to thinking about whether it would ever be possible for a civilization, in the aggregate, to become truly sentient and self-aware.  I don’t mean that the members are self-aware; obviously they are already (at least some of them, and to varying degrees).  I mean, could the civilization as a whole develop self-awareness, develop what the philosophers of mind call “qualia“.

Our civilization is probably far too small to instantiate such a thing, currently.  There are after all “only” about 8 billion humans on Earth, compared to, for instance, the roughly hundred billion neurons in each individual human brain (mileage may vary) and tens of trillions of cells in an entire human body.  But perhaps, someday, if a civilization becomes large enough and remains interconnected enough, the lights may come on, so to speak–actually it would probably be a gradual process, rather like those European, “energy-saving” lights; it’s unlikely to be an instantaneous change.  But it could, in principle, happen.

Of course, those who espouse the so-called Hard Problem of Consciousness™, might say that it could never happen, that qualia, that true consciousness requires some other ingredient or process.  I’ve never encountered an argument from any of them that impresses me, though.  Even Roger Penrose’s ideas about quantum mechanical processes being necessary for human consciousness–in denial of the Church-Turing Thesis and related ideas of universal computation–seems to me to be pure motivated reasoning, albeit by one of the great minds of the modern world, so it’s still worth exploring his ideas.  Even when he’s wrong, Penrose’s thought is more fruitful than that of the vast majority of people when they right, yours truly included.

I’ve arrived at no conclusions, of course.  It was just an interesting mental diversion that I thought I would share with you readers, since I have no one else with whom to share such things.  If any of you have any thoughts or ideas about them, please feel free to leave a comment below, here on my blog proper, not on other social media–I would prefer a forum in which other people who read comments on my blog could comment, too, and that’s not likely to happen on Facebook or on “the site formerly known as Twitter”.

Okay, that’s it for today.  I’m not going to edit this much before posting, so apologies if there is any persistently awkward wording or if there are any unnoticed typos.  Have a good “Not Memorial Day” day**.

*Of course, everything in the universe behaves locally–even quantum entanglement is “local” in a very specific sense.  Even gravity is local–the local gravitational “field” responds to the state of the nearby gravitational field, not literally to distant objects, which is part of why gravity can “escape” from black holes.  The larger-scale laws of nature emerge “spontaneously” from all these tiny, local interactions, or so it seems based on the best information I have.

**I mistakenly thought today was going to be Memorial Day because people at work kept talking as if it were.  However, that holiday is next Monday.  Sorry if I confused anyone, and thank you to my cousin for pointing it out to me.

The great blog itself, yea, all which it inherit, shall dissolve

Hello and good morning.  It’s Thursday, and even though I’ve been writing blog posts nearly all this week so far—since I haven’t been writing fiction—this is now my more “traditional” blog post for the week.

I apologize for not writing fiction yesterday and the day before.  I’ve been feeling terrible and horrible and no good and very bad and all that other stuff.  My coworker is still out, though he’ll probably be back sometime today, or possibly tomorrow at the latest, and anyway, that’s not the main problem.  The main problem is that I have been just terribly tense and anxious and have had terrible nights’ sleep even for me, despite trying to sedate myself and optimize my bedtime habits and so on.

Last night I got almost six hours of sleep, which for me is quite good, though it doesn’t feel close to enough.  It would be one thing if I slept six hours and awoke feeling refreshed and healthy; then I would know that I had gotten enough sleep, that six hours was just how much sleep my body needed.

Alas, things are not that simple.  My body’s optimal sleep time is probably pretty typical at around eight hours, but that particular “pressure” in the system is countered by whatever the various sources are of tension and stress and pain and depression.  When the sleep need gets too strong, it overpowers those other vectors, but as soon as it dips below some threshold, those other vectors dominate enough to push me into unpleasant wakefulness again.

I can literally remember the last time I got a good night’s sleep; I’ve probably mentioned it here, before.  I don’t know the specific date, but it was in the mid-1990s*.  (I’m being completely serious about this—as serious as a bloodcurdling scream for help.)

Last night, I walked about three-fifths of the way back from the train station in the evening—about three miles.  It was quite warm out, certainly in the high 80s, so I think I sweated a lot.  At least that meant I didn’t need to wake up to use the bathroom!  Also, I was physically fatigued enough to rest, and I’d been careful to try to balance my walking so that my left knee wasn’t acting up, which seems to have worked reasonably well for the time being.

I know that’s all very boring.  I just don’t have anyone else to whom to talk about these things, so I share them with all of you.  Aren’t you lucky?  I guess you can always just skim over the boring stuff.  I’m not sure how it is that we can tell what’s going to be boring before we literally read it, but people do seem able to do that, and it works.  I’ve done it myself.

I apologize for not writing any fiction since Monday morning.  I don’t know if any of you were angry at me for that, but I feel that I owe an apology.  I guess I really owe an apology for being a big annoyance and a downer, but I don’t know what to do to change those things.

I don’t want to be a blind optimist, of course.  I want to understand the world as clearly as I can, as objectively as I can, and as deeply and broadly as I can.  Maybe there’s no way to do that without being tense and depressive.  The universe is, after all, vast beyond intuitive understanding, and the realms at which fundamental physics applies are tiny and intricate, also beyond ready intuitive understanding, and time is old in the past and so much longer in the future than a person with a finite lifespan can truly take on board.

But I don’t think that must be despair-inducing.  I’m much more stressed out by how little humans seem even to contemplate how small they are, both individually and collectively, than I am by my own smallness.  As I learn more about how the world really works at deep levels, I don’t feel frightened or overwhelmed by it, like some Lovecraft protagonist who goes mad when confronted with the Great Old Ones or whatever.  I feel that I have grown larger—not literally, of course, but the phase space in which my mind exists takes more and more of reality into itself, and it’s really quite cool, if that’s the right word.

I think at least one thing that makes me feel despair is that so few other people seem even to want to understand the greater universe in any depth or breadth.  They would much rather imagine that the universe is very small and brief, as long as they are somewhere near the center of it.

But of course, to paraphrase Gandalf, they can shut themselves into their tiny little world, but they cannot shut the universe out.  And this in turn invokes not merely the old saw that nature, to be commanded, must be obeyed (for indeed, one cannot do anything but obey nature).  But I would say, far more strongly, that nature, to be survived—even to have a chance of being survived—must be understood as well as possible.

If you don’t know the rules of chess, you’re unlikely to be able to win a game.  Likewise with any other game, including even simple video games.  But those games have rules that humans invented.  The rules of nature have to be probed and unlocked and discovered, and they are much more fine-grained and large and complex than any human-made game could be.  They must be so, for the entire human world is but a tiny little part of that game, one of the innumerable things it allows to come into being.

Oh, well.  What are you going to do?

I guess you’re going to write a blog about it, and in the meantime, try to learn as much about the world as you can, because it is interesting at many levels.  And, of course, you can write a bit of fiction, to which I’ll try to return tomorrow morning.

In the meantime, I hope the vast majority of you are getting better rest than I have been getting.  I hope you have a very good day.  And I hope you have friends and family with whom to spend your finite and precious time.

*I remember waking up feeling absolutely refreshed, and though I was too young to think about feeling “ten years younger”, I did feel more alive than I had in some time, almost as if I’d gotten superpowers**.  I’ve known people who seem almost addicted to sleep, and if that’s how they tend to feel when they’ve slept, I can hardly blame them.

**Speaking of which, I have a stupid, joke superhero idea that I’ve been too embarrassed to share with anyone in person (I’m sure you’ll understand why):  “Bitten by a radioactive wildebeest, Anthony Edward Lopez finds himself with slightly-greater-than-human powers of strength and speed.  Deciding to use his new powers to fight crime, he becomes:  Gnu-man.”

Brief Tuesday Report (4-30-2024)

I didn’t go quite as wild with writing today as I did yesterday, but I still did write another 1,550 words.  My “short story” is already almost 30,000 words long, which is roughly as many words as are in Of Mice and Men, so I guess it counts as a novella.  A lot of my “short stories” turn out that way.  I’m not even sure how long Outlaw’s Mind is, so far, and that was intended to be a short story*.

Of course, as I said, I mean to pare it down quite a bit, but there’s only so much I’ll be able to do, and the story isn’t finished yet.

I also played guitar and sang a little bit.  I don’t know how well my playing is going–my thumbs are still painful.  But my voice is getting into better shape, at least, I can tell that much.  It’s not really worth anything to anyone but me, but it’s still a positive, I guess.

I’ve also recently started taking the Calculus course on Brilliant, since I recently decided to download the app to my phone as something to do in spare time.  I don’t necessarily think it’s a good way for me to study physics, but it’s a good way to review, and then maybe to learn, some mathematics.  It’s good to start with the basics, which I’ve already long since studied, because it feels quite easy, and that’s a nice way to build up.  I mean to work on the linear algebra stuff and further materials, because I’ll need that if I want to really understand General Relativity, so I can truly get why uniform energy in spacetime leads to repulsive gravity.  All the rest of it makes intuitive sense to me, but I need to wrap my head around that clearly and precisely, or I won’t be satisfied.

Anyway, that’s it for today.  I hope you have a good one.

*Chortles of derision are understandable.

And simple truth miscall’d simplicity, And captive blog attending captain ill

Hello and good morning.  It’s Thursday again, and so it’s time for a more fully fledged blog post for the week, in the manner in which I used to write them when I was writing fiction the rest of the week (and playing some guitar in the time between writing and starting work most days).

I’ve been rather sick almost every day since last week’s post, except for Friday.  I don’t think it’s a virus of any kind, though that may be incorrect.  It’s mainly upper GI, and it’s taken a lot of the wind out of my sails.

I haven’t played guitar at all since last Friday.  I’ve also only written new fiction on a few of the days—Friday, Monday, and Wednesday, I think—since the last major post.  Still, on the days I wrote, I got a surprisingly good amount of work done, I guess.  It seems as though Extra Body is taking longer than it really ought to take, but once it’s done, I’m going to try to pare it down more than I have previous works, since my stuff tends to grow so rapidly.

I’ve been trying to get into doing more studying and “stuff” to correct the fact that I didn’t realize my plans to go into Physics when I started university.  I had good reasons for this non-realization, of course, the main one being the temporary cognitive impairment brought about by heart-lung bypass when I had open heart surgery when I was eighteen.

I’m pretty sure I’ve written about that before, but I didn’t know about it then, and I didn’t learn about it until I did the review paper I wrote for my fourth-year research project in medical school.  I just felt discouraged and stupid, though I consoled myself by studying some truly wonderful works of literature as an English major, including once taking two Shakespeare courses at the same time.  That was great!

It’s always nice to learn about things, all other things being equal.  I don’t think there are pieces of true information about the world that it is better not to know.  Our response to learning some intimidating truth about the greater cosmos may not be good, but the fault then lies not with the stars but with ourselves.  If you truly can’t handle the truth, then the problem is with you, not with the truth.

Of course, knowing what is true is generally not simple, except about simple things, and often not even about those.  This is the heart of epistemology, the philosophical branch that deals with how we know what we know when we know it, so to speak.  The subject may seem dry at times, especially when it gets weighed down by jargon that serves mainly just to keep lay people from chiming in on things—at least as far as I can see—but it is important and interesting at its root.

Not but what there can’t be good reasons for creating and using specific and precise and unique terms, such as to make sure that one knows exactly what is meant and doesn’t fall into the trap of linguistic fuzziness which often leads to misunderstanding and miscommunication.  That’s part of the reason most serious Physics involves mathematical formalism; one wants to deal with things precisely and algorithmically in ways that one can make testable and rigorous predictions.

Physicists will sometimes say that they can’t really convey some aspect of physics using ordinary language, that you have to use the math(s), but that can’t be true in any simplistic sense, or no one would ever be able to learn it in the first place.  Even the mathematics has to be taught via language, after all.  It’s just more cumbersome to try to work through the plain—or not so plain—language to get the precise and accurate concepts across.

And, of course, sometimes the person tasked with presenting an idea to someone else doesn’t really understand it in a way that would allow them to convey it in ordinary language.  This is not necessarily an insult to that person.  Richard Feynman apparently used to hold the opinion that if you truly understand some subject in Physics, you should be able to produce a freshman-level lecture about it that doesn’t require prior knowledge, but he admitted freely when he couldn’t do so, and was known to say that this indicated that we—or at least he—just didn’t understand the subject well enough yet.

I don’t know how I got to this point in this blog post, or indeed what point I’m trying to make, if there is any point to anything at all (I suppose a lot of that would depend on one’s point of view).  I think I got into it by saying that I was trying to catch up on Physics, so I can deal with it at a full level, because there are things I want to understand and be able to contemplate rigorously.

I particularly want to try to get all the way into General Relativity (also Quantum Field Theory), and the mathematics of that is stuff that I never learned specifically, and it is intricate—matrices and tensors and non-Euclidean geometry and similar stuff.  It’s all tremendously interesting, of course, but it requires effort, which requires time and energy.

And once other people have come into the office and the “music” has started, it’s very hard for me to maintain the required focus and the energy even in my down time, though I have many textbooks and pre-textbook level works available right there at my desk.  I’ve started, and I’m making progress, but it is very slow because of the drains on my energy and attention.

If anyone out there wants to sponsor my search for knowledge, so I wouldn’t have to do anything but study and write, I’d welcome the patronage.

But I’m not good at self-promotion, nor at asking for help in any serious way.  I tend to take the general attitude that I deserve neither health nor comfort in life, and I certainly don’t expect any of it.  I’m not my own biggest fan, probably not by a long shot.  In fact, it’s probably accurate to say that I am my own greatest enemy.

Unfortunately, I’m probably the only person who could reliably thwart me.  I’m sure I’m not unique in this.  Probably very few people have literal enemies out there in the world, but plenty of people—maybe nearly everyone—has an enemy or enemies within.  This is one of the things that happens to beings without one single, solitary terminal goal or drive or utility function, but rather with numerous ones, the strengths of which vary with time and with internal and external events.

I’ve said before that I see the motivations and drives of the mind as a vector sum in very much higher-dimensional phase space, but with input vectors that vary in response to outcomes of the immediately preceding sum perhaps even more than they do with inputs from the environment.  I don’t think there will ever be a strong way fully to describe the system algorithmically, though perhaps it may be modeled adequately and even reproduced.  This is the nature of “Elessar’s First Conjecture”:  No mind can ever be complex enough to understand itself fully and in detail*.

A combination of minds may understand it though—conceivably.  Biologists have mapped the entire nervous system of C elegans, a worm with a precisely defined nervous system with an exact number of neurons, and of course, progress is constantly being made on more advanced things.  But even individual neurons are not perfectly understood, even in worms, and the interactions between those nerves and the other cells of the body is a complex Rube Goldberg machine thrown together from pieces that were just laying around in the shed.

Complexity theory is still a very young science.

And the public at large spends its energy doing things like making and then countering “deep fakes” and arguing partisan politics with all the fervor that no doubt the ancient Egyptians and Greeks and Romans and the ancient Chinese and Japanese and Celts and Huns and Iroquois and Inca and Aztecs and Mayans and everyone else in ancient, vanished, or changed, civilizations did.  They all surely imagined that their daily politics were supremely important, that the world, the very universe, pivoted on the specifics of their little, petty disagreements and plans and paranoias**.

And so often so many of them, especially the young “revolutionaries”, whose frontal lobes were far from fully developed, were willing to spill the blood of others (and were occasionally even willing to sacrifice themselves) in pursuit of their utopian*** imaginings.  This is true from the French Revolution to the Bolsheviks to the Maoists and the Killing Fields, and before them all the way back to the Puritans of Salem, and the Inquisition, and the Athenians who executed Socrates, and the killers of Pythagoras****, and the millions of perpetrators of no-longer-known atrocities in no-longer-known cultures and civilizations.

And then, of course, we have the current gaggle of fashionably ideological, privileged youth, who decry the very things that brought them all that they take for granted, and who will follow in the blood-soaked footsteps of those I mentioned above—l’dor v’dor, ad suf kul hadoroth, a-mayn.

In the meantime, I’ll try to keep writing my stories, and try to keep learning things, and if I’m able to develop an adequate (by my standards) understanding of General Relativity and Quantum Field Theory, it’s just remotely possible that I might even make legitimate contributions to the field(s).  But more likely I’ll self-destruct, literally, well before any of that happens.

I’ve probably gone on too long already, as has this blog post.  I thank you for your patience with my meanderings.  Please try to have a good day, and I hope those of you who celebrate it are having a good Passover.

*This implies that Laplace’s Demon could not be within the universe about which it knows the position and momentum of every particle and the strength of every force.  It needs to be instantiated elsewhere.

**Should that be “paranoiae”?  It feels like that ought to be the formal way of putting it, but Word thinks it’s misspelled.

***Not to be confused with “eutopian”.  Utopia means “no place”, whereas Eutopia would mean “good place” or “pleasant place” or “well place”.

****He was caught despite a head start, so I’ve heard, because he refused to cross a bean field, believing that beans were evil.  He was a weird guy.  It’s apparently from his followers that the term “irrational”—which originally just meant a number that cannot be expressed as the ratio of two whole numbers—developed its connotation as “crazy” or “insane”.  They didn’t like the fact that irrational numbers even existed.  Too bad for them; there are vastly more irrational numbers than rational ones…an uncountable infinity versus a “countable” infinity.  It’s not even close.

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.

Would YOU eat Zel’dovich pancakes for breakfast?

It’s Tuesday, and I’m writing another blog post rather than throwing some kind of curve ball and doing my fiction writing today, since I wrote a blog post yesterday, when I had scheduled myself to write some fiction.  I don’t know if that counts as a double curve ball or as a capitulation to a simple, over-the-plate, none-too-fast soft pitch.  It’s probably the latter, but I suppose there is no absolute right answer, and the judgment would depend upon one’s point of view.

I’ve realized that, contrary to what I wrote yesterday‒to what I honestly thought was the case‒I did not bring my small laptop computer with me when I left the office on Thursday.  I had unplugged it with the intention to pack it, but then I had left without it.  I can’t recall ever having done that before.  It goes to show just how crappy I felt on Thursday, I guess.

I really want to keep writing fiction.  It would be a shame to take this new story that I’ve well begun, with over 10,000 words written so far, and let it just fall by the wayside.  Then again, I’ve left The Dark Fairy and the Desperado hanging, and more egregiously, I’ve left Outlaw’s Mind hanging, so it’s not as though there is no precedent.  And, of course, in the past I’ve left stories incomplete many, many times.  But it seems particularly sad, now that I’ve published 5 novels and 2 collections of “short” stories, to fall back into that pattern.

But I need to find a way to be able to work fiction writing into my daily routines without messing up habits that have become somewhat compulsory for me.  I’ve tried to find ways to block out the noise in the office, so far without much success.  Yesterday I bought a rather inexpensive pair of noise-canceling headphones.  They didn’t do that good a job at the noise canceling; they reduced it a bit, but it was still there, though if I put in earplugs as well and then also played a YouTube video about field theories and similar stuff, if helped, but that is certainly not a combination of measures I could take while trying to write fiction.

I’m of two minds (at least) about the headphones.  I’m glad I didn’t spend very much on them, since they don’t turn out to be as effective as my more old-fashioned, gun-range and airport style ear defenders (when combined with ear plugs).  They can also play music or the sound from videos, but I didn’t get them for that.  I already have things that can do that.  But I wonder if more expensive ones would do any better.

It’s a shame that no high-powered movie executive has read any of my books or stories and approached me to option them for movies or shows or anything, but it’s obviously not surprising.  I’m terrible at self-promotion, more by temperament than merely due to lack of skill.  This blog is my closest approach to self-promotion, and I spend most of my time here spewing my random and often depressed and depressing thoughts in some wishful, pseudo-Freudian free association kind of exercise.

Of course, it’s about as useful to me as Freudian psychoanalysis* ever has been clinically demonstrated to be for anyone, which is to say, very little, if at all.  Nevertheless‒and also like psychoanalysis for many of its patients‒it has been habit forming, and I feel awkward and disjointed without it.

Also, as I noted yesterday, it’s the only means by which I keep contact with anyone other than my sister in the world outside of the office.  I’ve really become a shell of my former self, and the fact that there is physically more of me now than there has ever been before only makes that more biting, the irony enhancing the contrast with the past, when I used to relieve suffering and save lives and be beneficial to the world.

Ah, well.  From a cosmic perspective, all such benefits will probably be transitory, or effectively be nonexistent.

Which reminds me:  yesterday I was looking at the abstracts of some recent papers on “quantum cosmology” uploaded onto arXiv, the preprint server.  Obviously, most of these subjects were well beyond my expertise truly to be able to follow, but I get the concepts involved in most of them.  Also, exposure to the mathematical formalism when I don’t know how to manipulate it often makes it easier to understand later, as there is familiarity and applicability that helps add to the more complete picture I gradually build in my mind about such things.

This has happened to me more than once in the past.  I don’t learn by rote, I learn by building mental models and maps and structures that link areas of knowledge and understanding together.  So, I don’t learn quickly, but I learn deeply and durably.  I think this is a much better way to go.

Anyway, that’s tangential.  What was amusing is, I read about a paper involving some deSitter** models of inflation in a universe which (if I recall the abstract correctly) was matter-dominated in early moments and so had no uniform pressure (unlike radiation-dominated situations, which, if I’m remembering correctly, is pressure intensive and homogeneous, and is how our early universe probably was).  In such models, if I understood the point correctly, you could find more noteworthy inhomogeneities than seen in radiation-dominated phases, which makes sense, since the radiation pressure works against gravitational collapse.

So, the model discussed would be unlike our universe, in which the CMB demonstrates extreme homogeneity, down to a few parts in a hundred thousand, even from one edge of the cosmic horizon to the opposite edge, encompassing regions that could never possibly have been in any form of direct causal contact at least since the hypothetical time of inflation.  The light from each side has only just now reached us, and so is only halfway across to the other side, and may well never reach it if the universe expands quickly enough.  Yet the temperatures are the same to a few parts in a hundred thousand, which is probably more than can be said about the room you’re sitting in now.

One type of this theoretical homogeneity in the model in the abstract had apparently been previously described as a “Zel’dovich pancake”.  This is apparently nothing new (first described in the 1970s), but is a really amusing way to think of a cosmic structure, and I kind of want to look into it and see what it describes, to see if I can understand, at least superficially, the math behind it.

Wow, that was a whole ‘nother tangent of much greater departure than before.  I think I’ll call that good for now for this day’s blog.  I’m kind of all over the place, and if I’m not too careful, I might undergo decoherence and split into multiple versions of myself.  That seems all too possible, since I’ve never been naturally inclined to very impressive coherence in the first place.

I will probably be writing here tomorrow.

*Not to be confused with the more general term “psychotherapy”, which can be useful depending on the type of therapy and the person receiving it.  CBT is one of the most effective of these; it didn’t work all that well for me, but I’m annoying and perverse, so that’s no surprise.

**DeSitter spacetimes are just spacetimes with positive cosmological constants‒like our universe, with its apparent “dark energy”‒which will tend to drive accelerating expansion.  The whole “holographic universe” concept was motivated, or perhaps inspired, partly by the Bekenstein-Hawking recognition that the maximal entropy of any region of spacetime is defined by the surface area of an event horizon the size of that region.  Any greater entropy in the region would add to the mass of the black hole associated with that horizon, and so would make the horizon larger; thus that is the maximal entropy for that initial region.  QED (Quod erat demonstrandum, not quantum electrodynamics) if you will.  The holographic principle regarding a universe has only ever been worked out for anti-deSitter spaces, with negative cosmological constants, which we know is not the case for the universe in which we live because…well, because we’re alive, and those spacetimes tend to collapse rapidly.

Surprise! It’s a Monday morning blog post

It’s Monday, March 25th‒only 9 more shopping months remain until Christmas‒and I’m writing a blog post today (on my smartphone) instead of working on my short story, even though I brought my laptop with me when I last left the office.  I left (slightly) early on Thursday, and did not go in on Friday, because I was feeling quite ill.  I don’t know exactly what the nature of the illness was/is, but it was probably a respiratory virus.  I’m mostly over it now.

I’m still at the house while beginning this, because I’m waiting for Uber/Lyft rates to come down to reasonable levels before I accept one.  It should not cost all that much to get a ride less than 5 miles away, especially when I tip generously*.  I also have a bus pass available, which is quite a bit cheaper, but that would take quite a bit longer, whether I use it to get to the train or all the way to the office.  So, I’m not going to do that today, probably, but I may do so in the near future (Also, there are no bathrooms on the buses, but there are ones on the trains; this, for me, can be a serious concern).

I decided to write a post today mainly because I feel that I’m releasing most of my connection, such as it is, to the larger world by writing fewer posts.  Certainly, my readership has declined by a significant percent per post already.  Of course, I doubt that more than a handful of people would notice that I was gone even if I stopped completely.  I don’t know if I’ll keep this up or not, but I don’t think I can keep going back and forth.  I have to have some kind of mental momentum/inertia** to keep doing one thing; bouncing from one to another doesn’t seem to work well for me.

Obviously I would like to keep writing my stories, but if I go back to that 4 to 5 days (or more) per week, I would lose practically all sense of connection with the outside world other than weekly calls with my sister.  I like those weekly calls, of course, but at least when I write my blog posts, I know that a dozen or two people are, in principle, aware of my existence, and at least some of them actually read my stuff.

I guess that’s the sort of immediate feedback with activation of dopaminergic centers of the brain (the nucleus accumbens and related structures) upon which social media and similar situations depend, and of which they take advantage.  But it is (almost) all that I have, really, so that’s that.  It’s not as though I have any friends.

My sister lives in the path of the upcoming solar eclipse (which doesn’t narrow her location down by much, so I don’t think I’m being indiscreet for saying so), and she invited me to come visit to see it.  I really was going to try; I renewed my state ID to make travel easier, and I looked into bus and train and airfare, and they all seemed not too unreasonably expensive (unless you want a private compartment on a train, which would be cool, but would be ridiculously costly).  Unfortunately, I don’t think I can do it.  The prospect of traveling in cramped quarters for even the length of a plane ride seems just too unpleasant to tolerate.

I’m sorry about it; it would be great to see my sister and neat to experience a solar eclipse.  But the neatness thereof would not outweigh the prospect of the trip.  It’s pretty pathetic, I know, but then I don’t think I’ve ever specifically claimed that I was not pathetic.  My frequent readers will probably agree that I have been wise not to so claim.

I’m not sure what to do about this writing situation.  I sometimes consider just writing my fiction and maybe trying to do voice recordings a little later in the day, then editing and posting those as YouTube videos and embedding those as posts here.  I had reasonably good positive feedback when I did that before, but I don’t know how long it would last.  Also, I don’t know if I would lose people who prefer to read rather than to listen to a “video”, what I call an audio blog.

It’s probably all pointless, anyway.  I don’t think many people will probably ever read my work, fiction or nonfiction, or listen to my talk or my songs.  Likewise, though I have technically done a small part to add to the scientific knowledge of humanity, specifically relating to gliotoxin***, I’m not likely ever to make any contributions to quantum field theory or particle physics or cosmology, because while I think I am capable of contributing to them, there’s too much catch-up necessary, and I am limited more in energy even than in time‒there’s too much to which I have to adapt myself from day to day, and that burns my willpower up like nobody’s business.

It’s not as though I can just stop working.  At the beginning of a week, I can find the energy to start reading texts and other things relating to the pertinent fields (not just quantum ones, ha ha), but by the end of any given Monday, I am already so mentally drained that, come Tuesday, I don’t usually crack a single text.

I am, regrettably, not independently wealthy, so I can’t just go off and study.  I am also not mentally suited to seeking out and applying to graduate programs in appropriate fields, nor would I know quite where to begin.  I’m also pretty old to start such a thing, though I consider that less of a concern.  Mainly it’s just an “executive function” issue, as they say.  Also, I don’t think I could in good conscience accept loans or grant money for education.  I don’t think I’m a good risk; I’m too likely to kill myself sometime before finishing any academic program.

It’s not impossible for an autodidact to achieve at least some things‒after all, everyone is really self-taught, since it’s not as though anyone can do the learning for someone else.  They can only point the way; everyone has to walk the path individually.

I’m very tired, though.  If I could sleep decently, it would be easier, I think, but maybe I’m wrong.  Like the fella once said, it would be a real kick in the head for me to develop good sleep and find that I didn’t feel any better, would it not?

It’s a test I’m unlikely to encounter.

Well, that’s enough for today.  I expect I’ll write another post tomorrow.  Have a good day.

*Of course, like restaurant owners in America, Uber et al rely on tips to make up a good portion of their drivers’ pay; that way they can keep a bigger chunk of the fees for themselves and pay less out of their own pockets.  I would say they should in good conscience do otherwise, but they’re in something like a Nash equilibrium (as are all the various American restaurateurs) in that if they change their practices, they will be outcompeted by others who do not, and no one will be helped overall.  It’s one of those situations in which true collective action or legislation would be required to correct the inadequacy.

**Remember, inertia doesn’t just refer to an object’s tendency to remain at rest, but also to its tendency to continue moving in a straight line (or at least along a geodesic) at a constant velocity.

***Don’t bother looking into it.  It’s esoteric and not terribly interesting for those not working in mycology.

“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.
