Most people are dead, and it will probably always be that way

I sometimes think about historically based films in which tragedies happen and deaths occur.  I know they’re highly fictionalized, but think of Braveheart and of Gladiator* and movies of that sort, where the loss of loved ones makes viewers sad but drives the protagonist to “great” deeds that change the course of local history‒or, well, that make the course of local history.  After all, one only knows history after it happens, and once it’s happened, one cannot change it.  One can be mistaken about it, one can misrecord it, one can lie about it, but one cannot actually change it.

Even if it were possible to time travel, going into the past to alter something, it wouldn’t change the history from which you came‒as even the Marvel movies have pointed out, you’d just have created a new future, a new history, local to you.  It wouldn’t change your previous one‒that would be paradoxical.

Yes, Back to the Future is bullshit.  This really shouldn’t surprise you.  It’s still a fun movie.

Anyway, that’s beside the point I planned to make.  I think of tragic deaths in historical dramas that we see and about which we feel heartbroken, or even about real historical horrors‒human made, like the vast slaughters of Genghis Khan’s hordes or natural, like earthquakes and volcanoes and tsunamis and the like‒and about all the deaths involved, and sometimes I think:  “They would all be dead now, anyway, no matter what.”

Not one single person who was born before 1900 is alive today, as far as I know.  If there is one, that human is an all-time record holder in longevity, and is unlikely to live much longer.  And I would probably bet my own life** on there being no one alive who was born before 1850.  Indeed, the majority of humans who have ever lived are dead.  It’s not as big a majority as it might be, given how long humanity has existed, but that’s only because of recent exponential population growth.

In principle, of course, with a fast enough exponential population growth, it would be possible for the majority of humans to be presently alive, even with current lifespans.  But that’s not sustainable in the real universe.  For it to be sustainable in the long run, eventually humans would have to expand their empire over matter and space at faster than the speed of light, and reach far beyond the cosmic horizon, which is impossible in principle, as far as we know.

I say “eventually”, but don’t let that mislead you.  It would happen with surprising speed.  There’s a well known fact that, given a typical doubling/generation time of about 20 minutes, and assuming enough resources, a single bacterium could multiply to a volume greater than that of the visible universe within a month.  I’ll try to check my math on that when I get to sit down with a pen and paper***, but whether the specific time of a month is not quite right, it’s in the right ballpark.

This is the sort of doubling that is thought to have happened‒at an even faster rate, of course‒during the “inflationary” stage of the universe, if inflation happened.  Of course, in a sense, if “dark energy” is really the cosmological constant, then we are still undergoing inflation even now, just with a slower doubling time.  That doesn’t help is with our exponentially growing human population, though; spacetime itself can expand at, functionally, faster than the speed of light****, but nothing travels through spacetime faster than light.

Anyway, we’re already slowing down our population growth rate, which is good, since Malthusian growth tends to be unpleasant for almost everyone.  Therefore, as time goes by, the fraction of all humans who are dead will probably more and more overtake the fraction who are living.  And all early deaths are, in hindsight, not too terribly early.

This is one reason I get slightly irritated by people who talk of “saving lives” or characterizing a person’s death, per se, as a tragedy.  If every death is a tragedy, then the anti-natalists are right, and each new life should be avoided.  But, of course, it’s not that death in and of itself is a tragedy‒or if it is, it’s an inevitable one that’s going to happen to us all, sooner rather than later.  Even a being that lived for thousands or billions or googols or googolplexes of years would come no closer to living eternally than does a mayfly.  This is a mathematical fact.

It’s suffering that is the tragedy, not death.  Death can be a decent shorthand, in certain circumstances, because‒as Carl Sagan pointed out‒if one is dead, there is very little one can do to be happy.  Then again, if one is dead, there is also very little that can happen to make one disappointed or sad or in pain or afraid.  And since these things are more common and sustainable, or at least more reliable, than joy is, life itself, as a shorthand, is at least as good an indicator of suffering as death is of loss of possible joy.

It’s possible, I think, to live without joy‒meaning that it can happen, not that it’s a state one can or should seek.  But I don’t know that it’s possible for any true living things, or at least any living things with any equivalent of a nervous system, to exist without suffering.

So, perhaps Dumbledore’s post-mortem***** admonition to Harry Potter could be truncated to “Do not pity the dead, Harry.  Pity the living.”  Full stop.

*Which should have been the title of the sequel to Jaws.

**That’s maybe not as impressive as it might seem, since much of the time I hate my life and myself.  But it’s the only life I have with which to bet.

***With a typical length of 1 micrometer (10-6 meters) and a doubling time of approximately 20 minutes (leading to 72 doublings a day), after only one day, a colony of bacteria would be roughly 4700 cubic meters in size, a cube more than 16 meters (just over 50 feet) on a side.  After 2 days, its volume would be about 2 x 1026 cubic meters, or a cube 280,000 kilometers long on a side.  That’s nearly the distance from the Earth to the Moon.  After the 2160 doublings involved in a month of doubling, that would yield a volume of 2 x 10632 cubic meters, or with a side length of about 5 x 10210 meters.  A light year is 10 trillion kilometers, or 10 quadrillion meters, which is “only” 1015 meters.  So that’s a cube with a side length of 5 x 10195 light years‒waaaaaay more than a googol light-years.  Indeed, if you subtracted a googol from that number, it would not change it to any degree measurable by any means known to humans (5 x 10195 minus 1 x 10100 is still, basically, 5 x 10195).  The visible universe is only about 92 billion light-years across, yielding a sphere with a volume of “only” 4 x 1080 cubic meters.  It’s not even close to the order of magnitude of a volume of 2 x 10632 cubic meters!  My estimate was far short of the mark.  But that only strengthens my point, doesn’t it?

****It doesn’t actually do so locally‒I suspect that is also impossible, since it would defy the speed of local causality.  It’s only the summation of all the local doublings spread across the entirety of space that can make distant points separate at faster than the speed of light.  Then again, can “traditional” inflation cause any kind of local superluminal expansion?  I don’t think so.  Could two points in space a Planck length apart separate at a local speed that exceeds c even during inflation?  I doubt it, though I’m not absolutely sure.  Of course, if space is mathematically continuous, then there are no two closest possible points, anyway.  Between any two points on the real number line, there exists an uncountable infinity of other points, no matter how arbitrarily close you make them.

*****Of course, if one can deliver admonitions, one is not really dead in any useful or meaningful sense.  But it’s fiction, and it’s magic within fiction, so leeway can be given.  We have no evidence nor have I encountered any even borderline convincing arguments for any “life after death” in the real world, unless you count things like multiverses or Poincaré recurrences or the like, and I don’t, since they really entail other versions of a person, not a continuity of personhood.

Monday’s blogger at least still likes to learn

Hurray, hurray.  It’s Monday.

It’s probably hard to tell from the printed words, there, but I was being sardonic with that opening pseudo-exclamation.  I’m not excited that it’s Monday and the beginning of a new work week.  Then again, I’m not excited by much of anything.  Staying at the house doesn’t seem likely to be exciting, either.  There’s not much I can think of doing or any place I can think of going that seems exciting.  Nearly all the things in the world are on some spectrum from boring to stressful.

I don’t recommend this as a way of being, not even to myself.  I’m trying to find ways around it, or rather, to counteract it, but all my previous attempts have not succeeded in any durable fashion, as should probably be obvious.  Various medications, various therapies, lifestyle changes, exercise‒none of it has worked.  Some time ago, I had some hopes that trying marijuana that a former friend had would at least help my pain, if not my depression, but it did neither after two tries, and when I tried too much when I was in particularly bad pain, it made me quite sick to my stomach.  I was throwing up for a few hours (not continuously, of course, but it was still pretty bad).

It’s ironic that THC is used to treat nausea in many cases.  Evidently, my nervous system is too atypical for such things.

I recently happened upon some videos about psilocybin, specifically that there’s a study beginning on using it to try to treat some of the negative symptoms of autism spectrum disorder.  I know it has been used to treat recalcitrant depression and related disorders, including depression in people facing terminal cancer.  Psychedelics have always sounded intriguing, and people make much of them, but I think, given my experiences with other meds, I would be very frightened to try any of them.  My mind is not my friend, and I worry that I would be particularly prone to a “bad trip”, and there’s no way to abort such a thing once it has started; one just has to go through it to the other end.

Speaking of being anxious and frightened of things that many people find beneficial, I had meant to retry riding my new bike yesterday, and perhaps to ride it to the train and then into the office today, but I find myself subtly terrified to do so.  The beginning of last week was just so exceptionally painful and horrible that I am frightened of reinitiating it.  I wish I could know that it’s something that would resolve after a time, but it seemed to worsen over the course of the three or four days I was riding, until by last Monday I was bed-ridden, and I was even grumpier and more cheerless than usual on Tuesday, if you can imagine such a thing.

I think I’ll have to forgo it.  My boss really liked the bike, and offered to buy it from me if I can’t use it, but then I need to get it up to the office, which would mean riding it.  I don’t see myself carrying it.

My train is coming in five minutes.  I’ll pause and then return to this once I get on the train.

***

Okay, I’m on the train now.  What was I talking about?  Oh, yeah, the bike.  I guess I could have it shipped up to the office.  I think Uber even provides services like that, or I could try to see if there’s a way to set up an Uber in a vehicle that can carry the bike.  It’s a thought.  I don’t see my boss making a trip all the way down to my place to pick it up.

I guess I should stick to walking, even though it’s slower.  At least I can listen to audiobooks and podcasts and such while walking.  Nothing beats The Fellowship of the Ring as walking accompaniment, since it’s all about a journey on foot.  Even walking has its troubles, of course‒I have spandex braces on my left knee and right ankle to address the little bit of walking I did yesterday, and the right side of my back is in moderate spasm.  But that sort of stuff is par for the course.  If/as I lose weight, some of that will decrease, and some of it may even disappear.

Life is annoying on so many levels.  But at least there are lots of videos on things like hyperbolic geometry and computers and tensors and matrices and Einstein’s field equations and things like that.  It’s often the case that if I find several different people explaining the same thing I end up with a much deeper understanding.  Each teacher or author or whatever approaches things in a slightly different way, with different emphasis.  When one sees a subject from multiple angles, one tends to get a more complete and thorough understanding of it.  In this, I guess it’s analogous to binocular vision, which gives us depth perception.

I really want to read Zee’s book on quantum field theory, but although these new glasses are better for such smallish print, I think maybe I should have gone even higher on the strength.  Maybe I’ll go to the drugstore over lunch and pick up a stronger pair.  It would get me a bit more exercise, at least.

Please don’t emulate or internalize my negative outlook on things; I have no desire to see a world where more people are depressed.  Do try to keep learning.  Try to build as accurate a map of the world‒in all senses‒as you can.  Be ruthless with yourself in that process.  Your biases will try to trick you, and they will never stop trying, so you need to apply active countermeasures against them.  It’s a pain, but it’s important (and often satisfying and even thrilling) to work toward as accurate a map as you can get, not one that shows a world the way you would like it to be or you believe it to be.  A poor map will be less likely to get you anywhere you might want to go.

Learning about science, troubles with reading and socialization, and (not) writing fiction

It’s Saturday morning, and boy was yesterday’s audio blog a little weird.  I think it’s not so much that I said anything particularly weird—certainly not for me—but rather the odd meanderings thing took, from musing on the fact that I’ve been losing any joy of any kind in my life, becoming more and more bored or even irritated by more and more things that used to be interesting, on to the various declining cinematic universes and finally to thoughts about General Relativity.

At least that latter part encouraged me to read some material and watch some relatively hard-core YouTube videos about General Relativity and its mathematics.  By “hard-core”, I don’t mean there was any graphic sex involved.  First of all, I don’t think they allow stuff like that on YouTube, but even more to the point, I don’t see how one could work such a thing into an educational video about matrices and tensors and stuff like that.  I mean “hard-core” as in being more in-depth than just a general information, analogy kind of educational presentation, and especially that it talked about the mathematics underlying the science.

Not that I’m against the more general stuff.  I certainly began all of my interest in science with general knowledge/information.  When I was a kid, growing up (which is what kids do if things go well), I had a whole bookshelf I called my “science shelf” full of various kid-level books about everything from biology to paleontology (there were lots of dinosaur books—my first career ambition was to be a paleontologist) to “how things work” kinds of books and so on.

I didn’t really start to have as much physics and astronomy related material until after Cosmos came out.  That show was the reason our family got our first color TV.  I also asked for (and received) a hardcover copy of the book for my 10th or 11th birthday (it came out in 1980, I think, so it should have been 10th), and I was very pleased.  That book and show really triggered my love of space-oriented and physics-oriented science, including—of course—cosmology.

I chose my undergraduate college precisely because it was where Carl Sagan was a professor, though I never did meet him.  I would have thought it presumptuous and appalling to try to seek him out and bother him with gestures of my admiration and thanks.  I tend to feel that way about inflicting myself upon anybody—friend, foe, or stranger.  I just feel that I don’t have any right to intrude upon anyone else’s life or time, and also that I frankly don’t know what to say if I do meet them.

It’s a bit sad, though.  By most accounts, Professor Sagan tended to be quite pleasant and positive toward people who liked his work, and he considered himself—according to him—first and foremost a teacher.  He certainly taught me a great deal.  Though his books are now somewhat out of date, they are mostly still great repositories of fact and interest, and they remain overflowing founts of wonder.  I feel confident in recommending them to anyone, most prominently Cosmos, Pale Blue Dot, and especially The Demon-Haunted World.

Of course, I’ve read a lot of his intellectual descendants since then, and his cousins as well in other fields (Stephen Jay Gould’s and Richard Dawkins’s books and collections about biology are wonderful, too, for instance).  One thing I like about listening to podcasts that focus on ideas is that the guests are often people who have recently (or not-so-recently) written books, and if the subject is interesting I can read their books to get more deeply into their work.  I first encountered David Deutsch and Max Tegmark (and many others) on Sam Harris’s podcast, for instance.

And, of course, I have also read books by Brian Greene and Sean Carroll (and others) about physics in general.  It was to The Big Picture that I turned yesterday after my audio blog, in addition to the aforementioned video, to review some of the mathematical basics of General Relativity.  From there, maybe I’ll go on to the YouTube videos of Leonard Susskind’s* real graduate level lectures at Stanford, and to reading Sean Carroll’s textbook.  I’d also like to read through Zee’s Quantum Field Theory, As Simply As Possible, which I’ve mentioned before (with the thought of going on to his textbook if I can).

I have Zee’s layperson-oriented book in hardcover, but the print is small, and it’s difficult to read.  Still, I took delivery yesterday of a new set of reading glasses that are slightly stronger than the ones I was using, so I hope they’ll make it easier.  I’d really prefer to learn by reading than even by watching videos.

Of course, all this is probably just “pie in the sky” thinking.  My biggest difficulty is just summoning the will, the energy, to do these things.  It’s similar to the trouble I have with writing fiction.  I have quite a few story ideas I could write, but I have no drive, no desire to do the writing.  There’s no percentage in it, so to speak.  It’s not as though I have any fans out there telling me how much they like my books and want more.  I mean, my sister has read them all, and she liked at least most of them, and says she really liked The Chasm and the Collision.  That’s very nice, and I do appreciate it.  Apparently, though, it’s not the required stimulus for me to want to write more fiction.

Perhaps nothing would be.  Perhaps I’m just deteriorating too much, or have deteriorated too much.

Or perhaps it’s that I feel that a truly tiny minority even of people who engage with fiction do so in written form nowadays.  There’s too much competing immediate gratification out there, and primates—probably almost all life forms—are prone to fall for immediate gratification, and to someone else doing the imaginative work for them.

I fear that much of the general population has allowed their personal imaginations to atrophy, much as physical health atrophies when someone goes everywhere by car.  People even play Dungeons & Dragons online now, apparently.  That seems weird to me.  I don’t think I could really stand to play role playing games with strangers.  Playing them with my friends, as I did back in junior high and high school, for countless hours, was greatly enjoyable, and I think it did exercise and improve my imagination and my story-telling and story-creating “muscles”.

Oh, well.  I don’t have anyone with whom to do any of that stuff now, and I can’t even really imagine trying to find new people with whom to do it—see my above discussion about inflicting myself on people for part of the reason, but that’s not the only one.  I also don’t want to invest the considerable necessary stress and effort and anxiety into trying to find friends with whom I actually share interests—if such people even exist—and then have it all go sour or just go away as nearly every other relationship of any kind that I’ve ever had has done.  The juice, however delicious, is not worth that old vice-grip-on-the-testicles (and on all the joints and tips of one’s fingers) level squeeze.  The juice doesn’t last, anyway.

I’m on the train now, and I’m not exactly producing anything edifying, am I?  I’ll bring this week’s writing to an end, but I hope I’ll have the will to keep studying, at least.  And, of course, I hope most fervently and sincerely that all of you have a very good weekend.

*I also have his series The Theoretical Minimum in kindle and/or paperback and/or hardback form; his most recent one was about GR.  But I’ve had trouble reading physical books of any kind (let alone the Suss kind…ha ha) lately; I’m hoping my new reading glasses will help that.

Audio blog for Friday on anhedonia, fatigue, declining entertainment franchises and Newtonian and Einsteinian physics

This is an oddly meandering audio blog that I made this morning, having little desire to write much, and it goes from my troubles with depression and lessening interest in any former source of joy to the fact that even Star Wars and Marvel franchises are going downhill (with speculation about the causes) on to physics–first Newtonian then Special and General Relativity, and ponderings about the nature of near-light-speed travel and its potential effects when a spaceship passes the Schwarzschild radius in the direction of its motion (and even a tiny dabble into cosmic strings, which are not to be mistaken for the “superstrings” of string theory/M theory).  I find no firm conclusions, but maybe it’s mildly interesting somewhere.  It’s longer than I expected it to be, but hopefully not too long.

Don’t be afraid of “scare quotes”; they are–as am I–here to “help”

It’s Friday at last, the last day of a work week that has lasted at least 12 days already (subjectively speaking).  I am not working tomorrow, so there will be no blog post made again until Monday, barring‒as must always be the case‒the unforeseen.

I will try to remember to send myself the audio files for my last two audio blogs‒or perhaps it was three‒to turn into “videos” over the weekend.  I haven’t downloaded clipchamp or whatever it is to my home computer, but it should be no more difficult to do there than it was at work.  Of course, I may not do that, so don’t make any plans that depend upon my doing it‒goodness knows what such plans might be.

I’m not sure if anyone really likes those “video” versions of my audio blogs or is just as happy with the plain audio.  I’ve noted before that storage on YouTube is functionally limitless (as opposed to WordPress) but if I’m loading them here first, anyway, that’s a moot point at best.

You may have noticed that I tend to put quotation marks around the word “video” when I refer to the above, because though technically they are indeed video files, the visual portion is just a static image.  I’m a big fan of so-called scare quotes.  I think we should use them far more often than we do.  People often arrogate terms to themselves, or use epithets against others, as a means of manipulation, as if invoking some sequence of letters or sounds causes a thing actually to be the case, and I think it’s important to point out when one is unconvinced that the term is being used properly or accurately.

Perhaps the most prominent and pointed such ill-use might be regarding “progressives” and “conservatives”.  Both groups inherited the terms from people who came before, and who perhaps more accurately embodied the general meanings of the words, but they are now simply camouflage uniforms, at least in many cases.  You can call yourself a “freedom fighter” if you want, but using that term doesn’t mean you’re not a terrorist or that you’re actually interested in any legitimate form of freedom.

Of course, real conservatives and progressives being at hostile odds with one another doesn’t make much sense if one is considering the usual meanings of the terms rather than claiming them as team names in some tribal contest of primate dominance.  It makes sense to conserve those things in a society that are effective, that have been tested by time and found to be useful, but it’s just as reasonable that everyone should want to make actual progress whenever possible, to improve life and prosperity for everyone as much as is feasible.

The real, useful discussion would be about which things are working well and should be conserved, and which things require improvement and how to go about it.  There will be substantial disagreement on such questions, of course, and part of the discussion must always be how to decide what best to keep as it is and what is the most fruitful area in which to improve things

People of good will‒who do not think in terms of “us” versus “them” but in terms of usefulness and effectiveness and trying to get the best outcome for as big an “us” as possible‒can work in ways that will be beneficial by whatever measures one might want to use, keeping in mind always that all conclusions are in principle provisional and all processes and people are fallible, but that all problems are in principal soluble.

I’m not sure humans are clever enough primates to achieve such matters for long.  They seem to devolve so readily into conflicting tribes.  I guess this makes sense given the ancestral environment, with groups of only on the order of perhaps about 150 people living together.  But there’s no good excuse for not recognizing that tribal modes cannot function ideally in a setting in which 8 billion people are interacting in a massive and incredibly productive and complex economy and polity.  At higher levels of complexity, newer “rules” are going to tend to be required.

Humans aren’t necessarily all that good at adjusting to such things, though.  I often think that it will require a new and ongoing external threat, such as a supervillain or an alien invasion, to bring humanity together in total.  I’ve often been tempted to volunteer myself for the position, since humanity really can be contemptible and infuriating to me.

It’s not that humans are worse than the other life forms on Earth; I don’t think they are.  Life in general is frequently vicious and cruel and wretched, with all living things riding the knife edge of death and extinction much, perhaps most, of the time.  Nature’s equilibria are not achieved by some beautiful, fairy tale cooperation and self-restraint between forest creatures or what have you.  Equilibria are maintained by disease and death, by starvation and predation.  Agent Smith was just wrong, dead wrong, in his assessment of life’s tendency to form such natural equilibria.  He was too generous in his assessment of non-human forms of life.

Humans, however, are more competent than other animals.  They are also the only ones even capable of seriously planning ahead to strike a flexible and ever-changing balance between conservatism and progress.  It’s that they so often fail even to try to rise above their lizard-monkey minds that is so infuriating, and they themselves are among the worst of their victims.

Sometimes I think just wiping them all out would be a kindness‒not to the rest of the living world, which is certainly no more admirable or worthy of kindness than humans, but to humans themselves.  After all, if a function in time is always negative, then integrating the area “under” the curve will always yield a negative, and a permanent regression to zero would be a gain.  Maybe the universe, or at least the Earth, would be kinder in aggregate if it were sterile.

It’s food for thought, at least, and it is tempting.  What do you all think?  I’m not asking what you feel.  I hate feelings*.  But when you are as close to dispassionate and disinterested as you can make yourself, what do you think?  Does the human race (and by reflection, life itself) require an enemy to bring out its best?  If so, does it not then “deserve” that enemy?  And if it cannot defeat that enemy, does it not “deserve” to be destroyed?

I suspect that might be the case.

*Ha ha, that’s a little joke.

Thoughts on confident statements about scientific fallibility

This is some audio I recorded this morning trying to follow up on the subject I brought up near the end of my last “audio blog”.  It relates to overconfidence about scientific pronouncements and so on both by the experts and by those who think they know the “real” motivations of the experts, particularly relating to the issues in the pandemic and so on.  It was triggered by a snippet of a conversation between Bill Maher and Seth MacFarlane, but I’m not sure where to find the original snippet.

As you will note, I did NOT make it shorter than my last audio.

[There is an interruption in the middle–presaged and followed by three chirps–in which I say what I had meant to say upon bringing up a particular subject, but then distracted myself completely by discussing some excellent YouTube channels about science and math.]

Here are some links to the YouTube channels I mentioned (along with one or two I did not) and which distracted me.  I heartily endorse them:

PBS Spacetime

PBS Eons

PBS Infinite Series

Mad morning musings and “The End of All That Is”

It’s Wednesday morning again, and here I am, reverting to habit, writing a blog post (this time on my smartphone) because I frankly can’t seem to think of anything better to do with my time.

Well…I could sleep.  That would be a better use of my time.  Except I can’t sleep.  Even on weekends, the only way I get myself to sleep through the night is to take two Benadryl™ before I lie down.  But that’s not really effective, restorative sleep, and though I stay in “bed” later, I can tell the next day that I’m not really rested.  Or maybe that’s just residual effects of the antihistamine, I don’t know.

The best thing about when I was taking Paxil for my depression‒which didn’t work overall, and gave me bad side-effects‒was that it made me not just able to go to sleep at night, but to actually feel good going to bed and going to sleep, to enjoy the process.  I had never experienced that before, nor have I since.  But, as I said, there were other side-effects that made it quite bad.

Also, it made me gain weight, which would be particularly bad now, because I’m already heavier than I’ve ever been.  That’s what can happen when one’s only reliable pleasure comes from eating, and when one also eats as a sort of “stimming” and soothing thing to try to ease a constant sense of anhedonia and stress and dysphoria.  And it’s not as though I could simply “embrace” my body size, because it comes with worsening pain and other unpleasant consequences.

Unfortunately, I don’t get immediate worsening of pain when I eat.  It’s delayed.  If it were immediate, I would probably develop a habitual avoidance, and that would be great.  I try to remind myself, when my ankles and knees and back and hips are hurting a lot, that this is caused, at least partly, by eating too much, but that auto-suggestion doesn’t seem quite to work.

I’m pretty sure that I would eat less if I slept better.  Chronic sleep loss tends to affect one’s regulatory and stress hormones, and can stimulate appetite (especially for carbohydrates) in many people.  I appear to be one of these people.

I wonder if I could figure out a way to cause myself pain while eating‒maybe I could put a clothespin on the end of my pinky when I eat, every time I eat.  I don’t know if you all remember, but having a clothespin clamped on your fingernail hurts quite a lot, and hurts even more (albeit briefly) when you take it off and circulation returns*.

If I could arrange something like that to happen whenever I eat, that would be useful.  I did have a TENS unit that never helped my chronic pain, but some of its higher settings could be quite uncomfortable.  I suppose it might be useful to train myself, though it would require setting it up and activating it every time I ate.  Also, I’m almost sure that I threw it away in frustration because it didn’t work.

It would be really useful if I could somehow trigger nausea any time I ate, as in the style of aversion training seen in A Clockwork Orange.  I suppose I could try to force myself to eat eggplant with every meal…but no, I don’t think I could.  It’s very hard to force oneself to eat things that make one feel sick.  That’s the whole point of this line of thought.  I guess I could look for some syrup of ipecac.  I’ve never used that, but I think they used to use it to make people throw up if they’d eaten something poisonous or the like.  It might be worth a try.  I think I’ll send myself a reminder to look it up on Amazon.

The train just arrived.  I must say, Tri-Rail seems to have deteriorated slightly since changing their schedules, but maybe they’re just in the middle of making adjustments.  I try to give other people and organizations the benefit of the doubt when I can.  The Principle of Charity is one that I think would be very useful for society as a whole, or at least for humans:  the idea of trying to see what people say and do from the best possible light you can, instead of reflexively assuming the worst, of getting judgmental and self-righteous and assuming anything you find even slightly uncomfortable is a personal attack on you, precisely because you feel uncomfortable.

If I took that attitude, I could definitely see myself trying to destroy the world or even the universe, because a lot of reality bothers me a lot of the time.  Fortunately, I know that my feelings are my problem and my responsibility, not anyone else’s.

Not that I don’t fantasize about global and even universal destruction when I’m feeling particularly pan-antipathic.  I imagine working to perfect technology to adjust the course of asteroids.  I could even sneakily get government funding to do so, but then I could actually use the technology to steer near-Earth objects toward the Earth rather than away from it.  Some good asteroid hits might be extinction-level events, and a comet impact (of sufficient size) could wipe out nearly all life on Earth.

I say “nearly” because some microbes are remarkably resilient.

Of course, if one could study the possibility of vacuum decay‒causing, for instance, the cosmological constant or the Higgs Field to quantum tunnel to a lower energy level‒that would produce a wavefront process that would obliterate all forms of matter, a wavefront that would expand at the speed of light and wipe out everything.

Well…it wouldn’t literally wipe out everything, actually.  First off, it would leave behind whatever cosmos is entailed in the new Higgs (or other field) set-point.  And, of course, beyond our cosmic horizon, there are bits of reality that are moving away from us‒carried by the expansion of spacetime itself‒at faster than the speed of light.  So the vacuum decay wave would never reach them.  But it would obliterate everything in the observable universe, and that might be heartwarming enough.

Vacuum decay, though, may not even be a physical possibility‒it’s not a consensus prediction, though there are reasons to think it might be possible‒according to the best models we have of cosmic history, the Higgs field did settle out in a non-zero state after the electroweak era, and if inflationary cosmology is correct, then the “inflaton” field similarly decayed.

Still, we also have no idea how (or if) such a decay could be triggered.  There is no apparent risk of initiating it through highly energetic physics, because there are constant, extremely high energy processes happening in the cosmos, and everything we can see is all still there, as are we.

Oh, and contrary to the X-Men comics’ Phoenix/Dark Phoenix saga, unfortunately, a “neutron galaxy” would not be “The End of All That Is”.  If such a “neutron galaxy” were to “appear” in the middle of the Milky Way, that would be bad for us, though its effects would take a while, since even gravity doesn’t travel faster than the speed of light.  But effectively, a “neutron” galaxy would be no more cosmically devastating than a supermassive black hole with the mass of a hundred billion suns or so.  That’s a big black hole, bigger than any we’ve seen (and probably too big to be expected to exist at the current age of the cosmos), and as with any black hole, if you get too close it can be bad news**, but from a distance its effects would be no more harmful than an ordinary galaxy of equivalent mass.

Oh, well, I’ll have to keep brainstorming ways to destroy the world or humanity at least.  Maybe biology is the way to go‒it might be possible to genetically engineer something like the Blob or the Chicken Heart that Ate the World.  Or one could deliberately make an AI that has the terminal goal to turn everything into paperclips, not by accident but on purpose.  That would be humorously ironic.  Or one could just make an AI nanobot, Von Neumann probe-style thing that literally had the sole programming to replicate itself as much and as fast as possible, using every available resource.

I’ve written before about how such a thing could even instantiate a new kind of galaxy-level natural selection.

I wonder what would happen if I tried to crowd-source a project to end all life in the universe, maybe with a “GoFundMe” page…

Anyway, my station is coming up, so I’ll draw my insane musings to a close for now.  I don’t know if I’ll write anything tomorrow.

*Don’t worry, this was not something anyone else ever did to me.  This was something with which I experimented on myself, because while it was painful, it was quite fascinating that the pain got worse when I first took the clothespin off.

**Although, with one that big, you could probably traverse the event horizon without tidal forces killing you‒at least not just yet‒by spaghettification, so it might at least allow for some interesting final experiences.

And the mazèd blog, by their increase, now knows not which is which.

Hello and good morning.

I’m writing today’s blog post on my smartphone, because I walked to the train this morning.  That’s not quite the non sequitur it might seem to be.  Given the new train schedule, I arrived here only a few minutes before the 6:20 train is due to arrive, whereas on the old schedule, I would have just missed the 6:10 and sat down to wait for the 6:30.  Of course, I could simply let the 6:20 pass and wait for the 6:50 and pull out my laptop to write my post while I wait.  Perhaps, in the future, I will do that.  Today, though, I don’t want to push back my departure any further.

I’m now on (actually, in) the train, and I was surprised to find my preferred, relatively isolated seat on the older style car free.  Combined with the feeling of achievement from already having walked about five miles today, that’s pretty nice.

Today is the Winter Solstice, at least for those of us in the northern hemisphere, meaning it’s the day of longest night, if you will.  Going forward, now, the nights will become shorter, though the change will be hard to notice at first, since, near their maxima and minima, the derivative of sine and cosine curves (well, any smooth curve, really) is around zero, meaning the rate of change of the function is very small.  For one brief instant‒one infinitesimal moment of time‒during this 24-hour period, that rate of change will be exactly zero.

But, of course, the rate of change itself is constantly changing.  This isn’t true of all functions, obviously.  The rate of change in a linear function is a constant, and the rate of change of a constant is zero.  That’s why it’s called a “constant”.  And the rate of change of zero is still zero, no matter how many times you would like to take that derivative.

Sine waves, however, are cyclical, and their derivatives are also cyclical.  The derivative (i.e., the rate of change) of a sine is a cosine…and the derivative of a cosine is a sine (inverted, I think, if memory serves, but that changes nothing fundamental).  So, even the derivatives of such cyclical functions are eternally cyclical.  There’s something very pleasing about that, at least to me.

Oh, by the way, it is the Summer Solstice today for those who live in the southern hemisphere.  This has been a smaller number of people than live in the northern hemisphere for as long as human civilization has existed, I think, largely because there simply is more land in the northern hemisphere.  Nevertheless, there are now many millions of people south of the equator, and so there are oodles of those for whom Christmas and New Year’s are summer holidays.

Summer ought to be slightly warmer for those in the southern hemisphere than for those in the north, since technically the Earth is at its closest approach to the sun in January.  However, the Earth’s orbit is very nearly circular, so the difference between aphelion and perihelion is tiny, fortunately for us.  Also, there is much less land in the south, and land heats up much more rapidly and noticeably than water, so that may completely swamp the effects of slightly different nearness to the sun.  I’m not sure.  If anyone out there has that information, please let me know.

It’s a bit interesting to think of those people who have grown up in the southern hemisphere, seeing all the movies and shows (and before that, books and legends) that associate snow and cold and the like with Christmas time and New Year’s.  Of course, the reasons would not be a mystery, but it still might feel peculiar, just as it might feel rather alien for a northerner to hear of someone going to the beach to celebrate Christmas.

Instead of building a snowman, maybe such people might build a sandman.  Actually, given the old horror short story about the Sandman‒not to be mistaken for Neil Gaiman’s admittedly also quite dark creation‒it might not be great to make a sandman as part of a joyous celebration.

Although, being rather dark myself, I consider the notion somewhat amusing.  Maybe there could be a kids’ story called Gritty the Sandman, instead of Frosty the Snowman (Anakin Skywalker would hate that).  But Gritty would be much harder to destroy than Frosty.  It takes serious heat to cause sand to melt, and even then it just becomes glass.  Imagine that:  they try to kill Gritty with heat and fire, and he just turns into a misshapen blob of living glass, with razor sharp shards for fingers‒more deadly even than he was before!

Wait, that was supposed to be a kids’ story, wasn’t it?  Sorry, I got distracted.  Still it would be fun to hear a song with the lyric, “There must have been some madness in that old silk hat they found.  For when they placed it on his head, he began to…”

…who knows what?

Anyway, I’ve reached the office now.  My pedometer seems to have accidentally reset while I was on the train, as it’s only showing one mile of walking, which is the distance between the station and the office.  That’s a bit frustrating, but I know that the distance to the station from the house is almost exactly five miles, so I’ve walked six miles so far, and I’ve now reset the little bastard, so we’ll see what I’ll do for the rest of the day.  Maybe I’ll have the gumption to walk back to the house from the train in the evening.  I feel okay now, from my walk, but I don’t want to overdo things and set myself back.

I’ll sign off for the moment.  Have a lovely solstice if you can, be it your summer or your winter.  But if you’re in the south, and you make a sandman, try not to bring it to life.  Quite apart from it having the nefarious power to put you to sleep at will, remember that sand is basically just ground glass, and that can have dreadful effects on bare skin or on your mucus membranes.  And you certainly don’t want it in your eyes!

I think I’m imagining a new kind of horror story here, albeit a spoofy more than spooky one.  We’ll see what comes of it.

It’s all a matter of degrees

It’s Tuesday morning, and I’m waiting for the second train of the day, the one I caught yesterday.  I slept a bit better last night than Sunday night.  That’s not saying much, but beggars can’t be choosers, as the saying goes.  It still feels a bit better, at least.  You know you’re in some weirdness when four or five hours of heavily broken-up sleep feels fairly restful, and you don’t even really consider bothering to go and catch the 4:20 train.

It’s relatively cool here in south Florida, by which I mean the current temperature is 57 degrees* according to my weather app.  This is, rather amusingly, lower than the app’s statement of what the low temperature overnight is supposed to have been.  Anyone paying attention might be excused for feeling that the app, in contradicting itself so flagrantly, should not be considered reliable.

Of course, it’s obvious that the app, or service, or whatever it is, simply doesn’t bother to update its “printed” overnight low prediction just for local minutiae.  It’s not meant to be too precise, and in any case, local temperatures can vary quite a bit.  The predicted low was 60, so it’s only off by 3 degrees.

Those who have not been thoroughly enough educated might think this is a five percent error—small, but not negligible.  That is not correct.  Both Fahrenheit and Centigrade are relative temperature scales, based around the freezing and boiling points of water, which is a useful, but provincial, set of benchmarks.

No, to get the correct error estimate we must work with the absolute temperature scale, or Kelvin, which begins at “absolute zero” the coldest “possible” temperature and goes up to whatever the maximum possible temperature is**.  So, the error in absolute degrees (which are the same size as degrees in Centigrade, by convention) would be 3 degrees times 5/9, or 15/9 degrees Kelvin.

Now, to get the predicted temperature in Kelvin, we first convert to Centigrade—by taking (60-32) x 5/9, or (28 x 5)/9, or 140/9, or about 15 and a half—then add 273 (which is what zero degrees Centigrade is in Kelvin, ignoring the digits after the decimal point).  So, the predicted temperature, in Kelvin, was about 288 degrees.  15/9 is one and two thirds degrees, so 1.67 degrees (taking 3 significant figures).  As a percentage of 288, that’s pretty tiny.

Here, I’m going to go to the calculator program on my laptop, and it gives me…roughly 0.58%.  That’s just over half a percent error.  Not too bad, when you think about it.  How often are your own estimates that accurate?  If you could pick stocks that well, you could rapidly become a billionaire, I would think.

Here’s a funny little aside:  the southbound train just pulled in across the tracks, and I’ve apparently used the Wi-Fi on that specific train before, because my laptop just prompted me to sign in.  The train is pulling away now, and it’s too late, but it must have a pretty good Wi-Fi signal.

Okay, on to other matters, none of which seem nearly as interesting to me.

I think I’m going to try to use the same person who helped my coworker (the one who had a stroke) get new health insurance at what appears to have been a very good rate to sign up for some for me.  I don’t even want to try to use Medicaid or Obamacare if I can help it.

I don’t trust the human government, anymore—as Radiohead sang, “they don’t…they don’t work for us”.  It’s not that I think the government overall is malicious or evil or whatnot.  It’s just that everyone in it is very small and parochial, working for their own local self-interest under local pressures and incentives.  It’s astonishing that they ever accomplish anything useful at all.

Ants and bees (and termites) do a much more impressive job when they build their hills and hives and mounds, but then again, they are individually less self-serving in many ways.  That’s not to their particular credit—it’s the just way nature has shaped them for their lifestyle and reproductive strategies—but it’s true, nevertheless.

Human governments, meanwhile, are made up of individually motivated creatures whose reproductive processes (and thus their drives and fears) are not much different from any other mammals’, but who try to work in ultrasocial settings as if they were some close relatives of Hymenoptera.  It’s a testament to the incredible power of language (particularly written language) that they accomplish anything at all.

When it has dealt with me specifically, “the” government has done far more harm than good, and most unjustly***.  The less I have to do with any level of their power—I will not grant them the word “authority”—the more comfortable I will feel.  I have a learned aversion and probably some form of complex trauma associated with such things.

I don’t see any reason to overcome that aversion, because I don’t see how it would make my life any better.  It certainly would not make local or state or national governments any less likely to grind me—or anyone else who isn’t massively wealthy and unscrupulous, which probably includes you—into bone meal.

With that, I’ll start to wrap things up for today.  It’s the fifth day of Hanukkah, so enjoy it.  Also, there are only a lucky 13 days left until the annual celebration of Newton’s birthday (they also celebrate some other guy’s birth on that day as well, and though he seems to have been a good sort of guy overall, he really wasn’t born on anything like December 25th).

Christmas was, of course, grafted on to a pre-existing solstice festival, and why not?  Heck, Newton’s birthday was only on December 25th according to the Julian calendar, so it’s at least a week or two out from the Gregorian “date of his birth”.  I could figure out the correct Gregorian date, but I can’t be arsed.  It’s a question with no gravity, no momentum, not even any real significant potential energy.  One might say it is of infinitesimal importance.

Have a nice day.

*Fahrenheit, of course.  If it were 57 degrees Centigrade, global warming would indeed have taken an abrupt turn for the very much worse, and we would all be in the express lane to extinction, unless it were a very transient phenomenon.  And, of course, if it were 57 degrees Kelvin, we would all already be frozen to death quite nicely, since even the nitrogen in the atmosphere freezes below 63 Kelvin, and oxygen is a liquid below 90 K (both of these numbers are at “normal” pressures, which would not prevail in these circumstances).  I don’t know quite what it would mean to be at a 57 degree angle outside—would that simply mean that everything in the universe had been rotated by slightly less than a sixth of a full circle?  Given the rotational symmetry of the laws of physics, from which comes the conservation of angular momentum, I don’t think anyone would even notice.  And, of course, the Earth rotates locally 360 degrees a day, by definition.

**If memory serves, it’s called the Planck temperature.  Anyway, this would be the temperature at which each local point in spacetime would be so hot that the local energy would make a black hole, and in any case, the usual laws of physics would break down.  However, of course, if that energy is uniformly spread out, as presumably it would have been in the very early universe, any local spacetime curvature might be entirely effaced, so there would be no such black holes, as all the universe would be full of such energy.  I think inflationary cosmology would imply that there never really was an era of such intense local energy, unless that would be the “inflaton field” itself, but I may be misremembering this.  Anyway, that’s getting well into speculative physics.

***I am, of course, inescapably biased in this assessment, and I honestly could in principle be convinced by argument and evidence that I am wrong.  Nevertheless, I don’t think I’m incorrect in considering that statement to be accurate and true, with a fairly high credence—certainly well into the mid to high 90 percent range.  In other words, if I considered about a hundred assessments in which I was comparably confident as I am to this one, I would expect to be wrong about only a handful of them.

Weird pegs hammered into “normal” holes and spiders living in beehives

It’s Saturday morning, and I’m sitting at the train station very early—quite a bit too early for the first train—because I was awake anyway, and there was no point in waiting around at the house.  The train station (like the office) in many ways feels more hospitable than the house does.  That’s not saying much, but there it is.

There seem not to have been very many people reading my blog these last few days.  Evidently, when I’m not focused on my mental illness—and it is mental illness, it is not mental health—people don’t seem very interested.  Or maybe there’s a change to the WordPress Reader algorithm so that people don’t see my blog pop up.  I know something has changed, because I can no longer directly comment (or see the comments of others) on my favorite website through WordPress Reader.  That may be because the person who runs that website finds me annoying.  It’s easy enough for me to imagine that other people find me annoying.  I find myself annoying, so it’s not exactly a new notion.  Still, it’s very disheartening to be ostracized, deliberately or accidentally, from my usual interaction at that blog.

I don’t have much heart from the start.

I was approached—figuratively speaking—by someone yesterday morning asking me to please get health insurance, and making suggestions about how to do so affordably.  I listened, because of who it was and, even more importantly, because of on whose behalf they were probably partly speaking (though I am convinced of the caller’s true personal good intentions as well).  I agreed, fine, I’ll get health insurance of some kind.

It’s not the money, mainly, that’s been in the way of me getting insurance.  It’s my self-loathing that mainly gets in the way.  Why would I want to maintain my health and try to live longer or healthier?  What is the point of such an endeavor?  I’m personally extremely unhappy, and in pain, and sleepless, and alone, for one thing (I guess that’s more than one thing, but you probably know what I mean).

At this stage I’m just a net drain on the world, anyway.  Surely, the whole planet would probably cheer up slightly—but noticeably—if I were gone, like a pond that’s been muddied by heavy rainfall finally clearing after the silt settles out.  Most people wouldn’t know why the world felt a little more positive, a little more hopeful, a little more pleasant, but it would still be the case.

Anyway, I said I would do it, so I will, unless something kills me first.

I was in a weirdly upbeat mood part of yesterday morning before that event, although my blog post was rather angry.  To give you an idea of how weirdly upbeat I was, I had finished writing the draft of my post and was getting ready to lie down on the floor of the office (I do this a few times a day to help my back) and I set my computer to install updates in the meantime.  And as I saw the computer message that informed me that it was “updating”, I thought, “‘Updating’…that needs to be the title of a rom-com.”

Immediately, I thought up and quickly wrote out the plot synopsis for the romantic comedy in question and emailed it via my smartphone to myself.  Later, I told my boss about it, conveying the basic story line, and he said—with some enthusiasm—that it was quite good and he thought people would really like that story, and would read such a book.

I had thought of it more as a screenplay sort of thing, to be honest.  I considered getting on Skillshare or something similar and doing a quick course on screenwriting, to write it up.

Of course, I’m not in such a good mood as yesterday morning—it went away by early afternoon, when I suddenly felt a burst of severe tension, as if someone had injected me with epinephrine while I wasn’t looking.  It’s not a good feeling, but I have it a lot of the time.  Anyway, I’ve pretty rapidly and persistently gone downhill since then.

So, I guess I’ll sign up for some form of health insurance.  I have some degree of inherent resistance to the idea, of course, a big one being just my honest difficulty dealing with bureaucratic matters, with paperwork and personal records and trying to fit my weird and distorted metaphorical pegs into the square and round holes laid out—quite unthinkingly—by the world.

That latter comment about things being laid out unthinkingly is important.  No one should imagine that the world as it is was ever truly planned or designed by anyone, whether out of beneficence or malice or otherwise.  Individual people and so forth have had plans and goals and ideas, but no one is big enough actually to design a society or a government or an economy or whatever.  It all just falls together, like salt crystallizing out of a strong saline solution, or rock candy forming on a string in a cooling bath of saturated sugar water.

There are tendencies to form certain kinds of patterns, of course, because of the nature of the constituents and their interactions, but if one were to arrange ten million such rock candy baths, no two of the products would be the same.

Rock candy is simple, of course, and its point and purpose are simple.  So, it doesn’t really matter what specific shapes might be formed when making it.  Societies and civilizations, on the other hand, can take all manner of forms, and these can be truly better or worse by any criteria one might choose to use to measure them.  But they are not inherently real, they are not inherently good, they are not inherently stable or ethical or fair or just, and maybe they never will be.

Justice (however one may want to define the term) does not happen on its own.  Even if one tries to achieve it, one must constantly reevaluate, reassess, tweak, and adjust how one approaches it, because it is not a simple problem, and each local solution will engender new problems.  Problems are solvable, of course, but that doesn’t guarantee that they will be solved.  Wanting to solve them is not enough, and even trying to solve them is not enough.

To achieve justice, or at least to optimize it, for even a group of a hundred people would probably be computationally impossible even using a physically maximal computer.  Even assuming one had a fully agreed-upon definition of the term, the adjustments needed to get everyone in the best possible place seem fit make the traveling salesman problem trivial by comparison.

As for achieving optimal justice for 8 billion people, well…that’s not even a pipe dream.  It’s not even laughable.  At best it could only really be achieved at individual levels or perhaps in small groups, but then again, there’s not even an agreed-upon definition of the term.  This is one of the reasons to be suspicious of people who claim to have all the answers or a “real solution” or whatever, especially if you think they are sincere.

True believers are dangerous, far more dangerous than psychopaths or the mentally ill, and they have done vastly more harm throughout history than all the most self-centered of sociopathic villains could ever do, even if given absolute power (or so I predict).  This is at least partly because anyone who thinks they absolutely have the answers for civilization or even a society is simply wrong.  They always have been, they always will be.  Finite entities cannot even fully understand themselves, let alone ultimate, complex aspects of the world around them, so they can never be mathematically certain that they have the final word on any question.  It is always necessary, in principle, to be open to criticism and testing, to updating beliefs, even if one is very close to being sure.

Anyway, I have trouble dealing with bureaucracies and forms and paperwork and everything.  It feels utterly unnatural and uncomfortable.  It always has, but when I was younger and had people in my life, I was more able to put in the effort.  But it’s always felt unnatural to me, and deeply so.

It’s a bit like a spider trying to become a member of a beehive—seeking nectar and pollen and tending larvae and warding off invaders to the hive and all.  Some of the spider’s attributes may be useful—silk and venom and potent things—but a spider does not live on honey and pollen, and it will not thrive in a hive (if it even stays alive).  A spider is an alien in a hive; it can no more live like a bee than it can grow wheat and thresh it and grind it and then bake and live on bread.  However long it lives, it will simply be suffering.

That’s how I feel about a lot of this shit.  But I’ll do it.  Maybe I’ll even try to write that rom-com.  I can write pretty easily.  Of course, knowing me, the rom-com would probably devolve into a horror story, but maybe that would be good in a way.  After all, I’ve had romance of one kind or another in all my horror stories, and there’s usually at least a little bit of joking.  Sauce for the romantic comedy goose…

At bottom, though, I really don’t want to be healthy and alive.  I mean, it’d be nice not to feel physically miserable as long as I am alive, but that desire is preprogrammed into the organism, and I cannot rewrite that programming.  I can, however, shut it down, or let it come to a shutdown on its own, since I cannot update it, despite the title of my potential romantic comedy.  Life is shit—and if you’re a cockroach, shit is life, but that doesn’t mean you can make high art with it.

Anyway, here comes my train.  Have a nice weekend.
