I’m not yet back to doing Shakespearean blog post titles

Hello and good morning.

It’s Thursday, and so this is the second day of my planned new habit of writing posts on Tuesdays and Thursdays and every other Saturday.  I don’t know how that pattern might affect my readership.  Maybe it will lead to fewer people reading my stuff because it will be coming out less often.  Maybe it will lead to an increase in readership because it will be a comparatively scarce resource, and that fact will both make people want to see it when it’s available and will make it less of a burden for people to commit to following it.  Possibly, it will have no appreciable affect whatsoever, and any changes that happen will be related to other variables entirely.

It seems most likely that it will be some messy combination of those three broad categories.

I did some writing on Extra Body yesterday, which was the plan, even though I had slept very poorly and had to catch up on some things at work, for which I hadn’t been able to summon the energy on Tuesday.  After my relatively upbeat morning post on Tuesday, I’m afraid my energy and my mood really crashed, and it’s very unclear to me why it happened, other than the rather broad and general global tendency on my part that makes me prone to such things.

While that is indeed a good description of aspects of my nature, it isn’t a very satisfying explanation for why things happen in specific ways on specific days, and it doesn’t allow me to make any choices about what actions to take based upon it.  As Eliezer Yudkowsky might put it, it doesn’t let me squeeze the future into any particular path, so it’s not useful.

Anyway, it was a very rough day, and several times just sitting in the office, I grappled with the urge to start crying, and several times I thought‒out loud in my head, as it were‒the words, “Somebody, please, help me.”  Of course, no one could hear my thoughts, so no one did offer any help.  It was a general, global request, or plea, anyway, not one specific to that day or time.

Getting back to writing fiction, though:  I wrote well over 1500 words, which was a little over two pages in the format I have now on Word, which I think is perhaps different than it used to be.  I don’t recall 750 words per page being usual, but maybe it was.

I had forgotten, I must admit, how much more relaxed it can be to write one’s pages for the day and not be expected to publish them that same day, in contrast to what I do when writing this blog.  I simply wrote a couple of pages of the story, and I could have written more, and then I was done with that writing for the day.  Sure, I’ll need to come back to it and edit it later‒I’ll do that a lot.  But on any given day, the process has a sense of relatively pain-free closure.

I even puttered around on the guitar for a few minutes after that, as a sort of nostalgic indulgence.  I used to do that most every day after I finished my three to four pages of draft writing.

With the blog, writing and then editing and then posting and sharing and all takes up much more time, and it seems to be more enervating.  No offense intended.  Maybe it’s a bit like drawing a daily comic strip, but drawing and releasing it on the day, every day.  That could be done, in the modern world, but I don’t think many comic strip creators would like it, and I think it would probably burn them out before long.

Still, at least people seem to read my blog.  If we compiled every individual instance of a single person reading any one of my fiction works‒meaning if someone has read three of my works, that counts as 3 instances‒you might have fewer instances than the number of people who at least look at my blog on any given day.  Certainly the number of people who have bought my books isn’t even within an order of magnitude of the people who subscribe to my blog.

Either way, I guess it doesn’t make much difference in the long run.  All these moments (and words) will be lost in time like tears in the rain, as Roy Baty said.

I did walk to the train this morning, though I did not do so yesterday, fearing the time loss it would entail.  That lack of exercise didn’t help or hinder my mood as far as I can tell, but it was probably good for my recovery, because today was easier.  I mean to keep doing this, as I’ve said, and eventually to add the walk back to the house as well.  It’s good for my health, it makes me “stronger”, and it gives me time to listen to educational podcasts and audible books on science and related topics.  I may even‒since there is no Audible version available‒read aloud and record Quantum Field Theory, As Simply As Possible for myself so that I can listen to it later.  Just the reading will likely get the concepts into my head well, and then relistening will cement them.

If that works, I may do it with other deep books that don’t have Audible versions.  I remember there used to be a service called “recording for the blind”, for which I briefly volunteered as a proof-listener, that provided audio textbooks for those who cannot see, and for which there are no braille versions (surely the supermajority of textbooks).

Anyway, that’s enough for now.  I have things I want to do, and I have an appointment this morning for an irritating, bureaucratic process that I have to do, or at least that will make certain other things simpler.  Just the prospect of it fills me with paranoia and stress.  I hope you have a good day.  And, since I am working this weekend, I expect to write a post on Saturday.

One of a new pair o’ digms

Hello again.  This is hopefully going to be the first event in a new pattern of behavior in which I write blog posts on Tuesdays and Thursdays and every other Saturday and write fiction on Mondays, Wednesdays, and Fridays.  The future is always in motion, of course, at least from our “worm’s eye view” of the universe without any access to enough information (let alone computing power) to make us anything like Laplace’s Demon, so things may not turn out according to plan‒but it is the plan.

I used the MS Word app on my phone to take a look at Outlaw’s Mind yesterday, just to see whether it looked like I might want to work on it again sometime.  I think it might benefit from eliminating the opening portion, which has an adult Timothy Outlaw approaching what will be (according to the original story idea) the climax of his tale.

I wrote this based on a story idea that I had written down in my “Story Ideas” file (appropriately enough), and the rest of the tale took off from there.  But I think‒perhaps‒that it has changed into a slightly different story than the opening idea, and I think it might be better if I just throw that little concept away and focus instead on the account of Timothy’s difficulties with rage and his exploration of his mind and its nature and the real or imagined horrific forces that plague him.  For one thing, this story connects with ideas that involve the larger Omniverse of my stories, including everything from The Chasm and the Collision and my potential story Changeling in a Shadow World, all the way back to my first completed (and now lost) book, Ends of the Maelstrom.

I like the process and concept of joining disparate fictional universes together, as in Stephen King’s whole Dark Tower concept, to say nothing of the (earlier) multiversal connections in comic books and graphic novels such as, for instance, Marvel/DC crossovers, and even, on a less “meta” scale, the merger of Asimov’s Foundation novels with his robot and empire novels and so on.  I’ve certainly done this on smaller scales myself already; careful and committed readers of my stories (if such people exist other than I) will know that the world of Unanimity is the same as the world of Hole for a Heart.

I guess that’s all still up in the air in many senses.  Extra Body, the story I’m ostensibly working on “now”, has some references‒highly speculative ones‒to a particular world of light-hearted, classic sci-fi.  It will be a rather nerdy sort of speculative connection, but I have no trouble with that.  I am certainly a nerd.

In other news, I did indeed walk to the train station again this morning, and I feel reasonably well, physically.  Yesterday I walked a total of about seven or eight miles, roughly, and I feel fairly okay.  I considered walking back to the house from the train in the evening, but my boss‒quite correctly, I think‒warned me against overdoing it.  This is quite sensible.  I think for most of this week I will stick with just the morning walk, but then next week I intend to add the return journey and eventually work my way along from there.

As for sleep:  well, I didn’t seem to get any worse a night’s sleep than usual, though it wasn’t particularly better.  I still started waking up very early, but knowing that I was going to be walking allowed me at least to put a decent spin on that fact, since I could just tell myself that, if I was unable to go back to sleep, I would just get up sooner and start walking sooner.  I did finally leave about five minutes earlier than yesterday, and I took a slightly different route, just to keep things fresh.

Yesterday while walking I listened to the audiobook of The Biggest Ideas in the Universe, volume 1, whereas today I listened to some of Sean Carroll’s latest AMA podcast.  I highly recommend this; it’s both enjoyable and educational.  In the book, yesterday, I had to rewind and relisten to portions a number of times when I realized I had zoned out on some things he said (or wrote).  That’s fine.  It helps me learn better.

I wish there were an audio version of Quantum Field Theory, as Simply as Possible, and some others.  I suppose I could offer to do the audio myself, and by doing it, would learn the subject better.  It’s something to consider.

We’ll see.  I’m going to call this to a halt for the moment because my train stop is approaching and‒funnily‒I’m dozing off while writing.  That doesn’t happen very often, but maybe I’m getting into a relaxed state because of the exercise.  Either way, I don’t want to miss my stop, so this’ll be it for today.  Talk to you Thursday.

Whither one goes affects whether the effects of the weather are noteworthy

It’s a bit chilly this morning, at least for south Florida.  As I looked at the weather app when I was getting up, it reported that the temperature near me was about 51 degrees Fahrenheit.  We can take 32 away from that then multiply by 5/9‒so that’s 19 x 5, which is 95, divided by 9‒which gives just over 10 degrees Centigrade (or Celsius, depending upon whom one asks).

I guess that’s pretty cool, though certainly there are many places north of here where people would welcome it as a relatively balmy day for this time of year.  Alternatively, in parts of the southern hemisphere, where it is summer, it would seem aberrantly cold, even more noteworthy than it is in my neck of the subtropical woods.  Going farther afield, on Mars it would be truly a record-setting heat wave, whereas on Venus, such a temperature would be impossibly, unfathomably cold.

The surface temperature of Venus is, if memory serves, around 900º Fahrenheit, or nearly 500º Centigrade, or nearly 800 Kelvin (I am rounding the Kelvin “273” addition to Centigrade because I only have one significant figure in my recalled estimate of Venus’s average temperature in Fahrenheit, and adding other specific digits would be misleading and unjustified).

It’s interesting that Venus, the planet named for the goddess of sexual and romantic love, is the most hellish planet in the solar system.  It’s hot enough at the surface to melt lead.  The atmospheric pressure is 90 times that of Earth and largely consists of carbon dioxide.  The cloud cover is constant and it rains sulfuric acid.

Perhaps Venus, the morning “star” (and the evening “star” too, depending on which side of the sun it’s currently on from Earth’s point of view) is more appropriately given one of its other names, which is:  Lucifer, the light-bearer, herald of the dawn, who in later mythology was associated with the Devil (at least before his fall).

Of course, it’s hard to reconcile Lucifer’s supposed fall with the fact that the planet is still conspicuously up there in the sky.  And I do mean “conspicuously”.  Apart from the sun and the moon, Venus is easily the brightest thing in the night sky.  Sometimes one can still see it even as the sun is beginning to rise; the cloud cover of Venus makes it highly reflective of visible light.

Anyway, I find it sardonically and cynically amusing that the goddess of love is associated with a nightmarish hellscape, but I have a personal history that makes me look askance at romance.  I am, in other words, biased.

Venus is a good object lesson in the potent effects of carbon dioxide’s tendency to allow visible but not infrared light to pass easily through it, and so to create a “greenhouse effect” even in the modest concentration it achieves on Earth.

The physics of this is well understood, relating largely to the resonant frequency of the bonds in the molecule as well as its size and shape.  Smaller, tighter molecules like molecular nitrogen and molecular oxygen, the two gasses that make up the vast majority of Earth’s atmosphere, don’t interact much with infrared light, and are more prone to scatter shorter, bluer wavelengths of visible light‒this is a rough explanation of why the sky is blue (and why the sunrise and sunset are much redder, as that sunlight is going through more of the atmosphere due to the angle at which we see the sun at those times of day, and the blue is partly scattered out of it, leaving relatively more redder light behind).

Anyway, the broad physics of the greenhouse effect is almost elementary, and has been understood for a long time.  The specifics of what precisely will happen in any given set of circumstances can be tricky to tease out, given the complexity of reality‒you might say that Venus is in the details‒but the specifics are often less important than the broad strokes.

After all, when a giant asteroid is heading toward the Earth, it isn’t that reassuring to know that only, say, 75% of species will be driven extinct by its impact, and that life will survive and eventually once again thrive.  How much would someone have to pay you for you to be willing to accept a 75% chance that just you will die, let alone everyone like you on the planet?

There might well be a big enough sum for you to be willing to risk your own life, especially if you got to enjoy the money for a while before the dice were thrown, or to leave it to your heirs.  But for your whole species?  Is there a reward big enough to be able to take that chance?  Let’s assume you’re not a raging misanthrope/panantipath like I am for the sake of this question, since depending on my mood, I’d be inclined to negotiate for a higher chance of extinction.

Also, of course, by pretty much every possible form of ethics you might follow, you don’t have the right to roll the dice on all the members of your own species.   You don’t have any right to roll the dice on the members of your own family, unless they unilaterally and spontaneously and freely grant you that right.

Sorry, I don’t know why I’m writing about these topics today.  They are just what spewed out of me, like vomit from the proverbial drunkard or pus from a squeezed abscess.  I wish I could write something more interesting, or write something that helped my mood some.  Writing fiction did at least help fight my depression, but it’s hard when almost no one reads my stuff.

Maybe I should take to writing at least a page of fiction a day by hand, on the notebook paper and clipboard I have at the office, during downtime, instead of watching videos.  Yesterday I mainly watched ones about spontaneous symmetry breaking and the electro-weak era and the Higgs mechanism.  To be fair to me, it’s very interesting stuff, and it actually would have some relevance to my potential comic book turned manga turned science fiction story, HELIOS.

Of course, that’s named for another mythological figure, one that’s even hotter than Venus.  But I don’t know if I can write it.  Motivation is difficult.  Still, as Stephen King reputedly once told Neil Gaiman, if you write just one page a day, by the end of a year you’ll have a decent-sized novel*.

Once I get writing, I have a hard time stopping at only one page.  If you’re a regular reader of my blog, you’ll probably know this implicitly‒my general target for post length is about 800 words, but I almost never am able to keep it that short.

I guess we’ll see what happens.  And, of course, I’ll keep you all…posted.

*He has also noted that, for him‒as I have often found it to be for me‒writing fiction is the best form of therapy.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Once again, no semi-Shakespearean title this week

Hello and good morning.

I have no idea about what to write today.  Yesterday’s rather long post took off from an initial notion that’s been with me for a long time*, with some tangents in between and so on.  The footnote about the doubling of bacteria took a bit of extra effort once I got to the office‒not much, though, since I was able quickly to look up** the size of a typical bacterium on Google, and the calculations were just “plug and chug”.

Thankfully, I already knew the dimensions of the other bits of trivia, like the size of the visible universe in light-years and the length of a light-year, though on my first round of calculations I got something very off with the volume of the visible universe.  I think I must’ve squared rather than cubed at some point, because it was much too small, and when I did my editing, I thought “that can’t be right”, and I redid the figuring.  Then, because of the mistake, I checked that result against Google/Wikipedia, and my correction was, at least, correct.

There, that’s a little discussion on “how the sausage gets made” so to speak.

That’s a curious expression, don’t you think?  Apparently, people prefer not to see how actual sausages get made.  I’m not quite sure why that’s the case, though.  Are people under some delusion that sausages are not made from various and sundry animal parts, at least some of which would not look as pretty as a nice steak if you served them “as they were” on a plate in a restaurant?

Sausages are meat.  They are parts of dead animals, ground up and stuffed together into some form of outer “skin”.  When done right, they are delicious.  This is because humans are opportunistic omnivores with a strong penchant for carnivory, and meat is a concentrated source of nutrients, the sort our ancestors‒the ones that survived to pass on their genes, anyway‒liked to eat because it was very beneficial.

That was a weird digression.  I’ll just say that, if you eat meat‒as I do‒and you are afraid to see how sausages are made, I don’t understand how you think.  I’m not suggesting that you ought to make your own sausages; division of labor is a terrifically useful thing, and makes all of civilization more efficient and indeed possible.  But to be in denial about sausages is a bit like being in denial about landfills and sewers, both of which are real and, for now at least, necessary.

I don’t know why I’m going on about this.  No one but my own brain raised the subject.  For all I know, every one of my readers has seen sausage being made (and seen waste treatment facilities and landfills) and has been perfectly fine and sensible about it.  Or, perhaps, they’re all vegans***.  Or perhaps they’re a mixture.

More likely, most of my readers are indeed opportunistic omnivores.  That seems a very sensible way for an animal to be.  I’ve read or heard of science fiction authors (and possibly even scientists) who speculate that most intelligent life forms would be omnivores.  There’s certainly some potential logic and reason there, but I suspect that mostly it’s projection and bias.  Certainly it is big speculation.

There are very good reasons to suspect that most if not all life will be largely carbon-based, due to carbon’s uniquely profligate chemistry and its near-ubiquity in the universe; those are matters of largely unambiguous physics and chemistry.  But as for the rest, our speculations are largely unguided and thus unconstrained, and we should be careful about even preliminary thoughts, let alone conclusions.

Of course, science fiction writers are free to speculate and invent.  That’s the job.  And within their created universes, they are the Gods.  But it’s important to know the difference between fiction and reality.  Reality is a much harsher taskmaster than fiction, and in reality, the wages of “sin” really are often death.

I think my own wages of that type are long overdue, to be honest.  I keep putting in claims, but HR and Payroll are, apparently, very inefficient.

.

Okay, sorry about the little pause, there; maybe you didn’t notice it, since it happened in a different time plane than the one in which you are reading, but it was there, don’t doubt that.  My train seems to be running late, but there has been no announcement about it, and it doesn’t even show up on the Tri-Rail tracker site, though the subsequent two trains do, and are listed as “on time”.  Why should they not be on time?  They’re due a half an hour and an hour from now, respectively.

.

There was another pause, there, just now, as I thought I saw the first glimmer of the headlights of “my” train, but alas, it was not so.  I don’t know what I’m going to do if it’s much later.  Trains get more crowded when they’re late and I hate that.  Maybe I’ll just get an Uber.  Maybe I should just go back to the house.  Possibly I should just lie on the tracks “in protest”.  After all, if the trains are going to be late and/or canceled anyway, I might as well give them a strong reason.

***

I have left the train station and am now en route to the office in an Uber.  The train showed no signs of arriving, and there was neither an announcement overhead nor any info online.  The Tri-Rail system used to be much better run.  It seems to be going to the dogs, lately.

Anyway, that’s enough for today.  To paraphrase Adele, I wish nothing but the best for you all.

*Another, unrelated one is, how did Princess Leia know to call Han Solo “Flyboy” when she said “Into the garbage chute, Flyboy!” in the original Star Wars movie?  She had not been told he was a pilot.  Was this an early hint of her natural ability with the Force?  Or was it, rather, just George Lucas accidentally giving her a line based on a fact he knew, but that her character would not?

**Google Docs tried to prompt me to split the infinitive and write “to quickly look up” rather than “quickly to look up”, which is what I wrote.  I hate such anti-grammatical suggestion-making!

***It might interest you to know, in loose relation to the present topic, that members of the dominant intelligent species in the star system Vega are obligate carnivores.  So, ironically, real Vegans only eat meat****.

****Of course, that’s all just a bit of sci-fi that I composed.  But wouldn’t it be hilarious if it were so?  I remember the first time I ever saw or heard someone use the term “vegan”.  It was in Bloom County, said by Steve Dallas, after he got his brain flipped by aliens, making his personality the opposite of what it previously had been.  I was already astronomically literate enough to know about Vega, and I wondered what the hell the character (and other, real people) meant when he/they wrote that they were “vegans”.  At first, I thought it might have something to do with astrology; the people involved seemed to fit that mold a lot of the time.

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.

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.

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

Be Smart

Numberphile

Sixty Symbols

Deep Sky Videos

Periodic Videos

My gruntlement is low today

It’s Tuesday morning.  I wasn’t actually planning to write anything when I got up today, but then I remembered that, more or less on a whim, I had brought my little laptop computer with me, so I figured I might as well write something.

For one thing, I’ll embed the “video” of my last audio blog—the one about Morgoth and whatnot—below, so if anyone prefers to do their listening via YouTube, they can do so.  Evidently, the Google podcast app is going to be phased out, and one is going to have to listen to podcasts via YouTube Music at some point in the future (or use some other service/app).  That’s a bit frustrating, because there’s at least one podcast that I get via subscription that one cannot get in its entirety on YouTube, but can get through the app.  I guess they’ll figure out a way to deliver that, but it’s irritating to have to change my settings once again.

I guess it shouldn’t matter.  I should just cancel all my subscriptions and services and platforms and even cable and internet.  They’re not really doing me any good, and they cost money, and honestly, I really would expect not to be alive starting sometime soon.  I’ve been expecting that for a long time, now, though, and I haven’t really been able to work up the gumption to bring it about.

I have at least been creeping my way in that direction.  I have flammable liquids for potential immolation—useful for other, more traditional things as well, of course.  I have scalpels and utility knives, useful for cutting various things, including oneself, but of course, they’re also generally useful for many things.  And recently I bought a nice length of rope—too long, really—and learned how to tie a hangman’s knot.  That last bit is rather surprisingly easy, and it’s a pleasant and useful knot, it turns out, especially to someone who used to be in the Boy Scouts a lifetime ago.  Ironically, it has many similarities to an informal necktie knot.

But, I’m still alive for the moment, though I’m very uncomfortable and unhappy in general, and I still haven’t gotten health insurance.  I get a near-panic feeling when I even think seriously about getting insurance.  I’m not entirely sure why that is.

Yesterday morning I felt really horrible, and I think it’s because I was trying to reintroduce some things I like into my diet to see if I can tolerate them.  I guess I can’t, at least not in the state I’m in (Florida).  It seems I can’t even enjoy the things I like to eat, but then again, I can’t expect nature to be there for my convenience.

I could try to work against nature’s convenience, in return, I guess.  At the very least, I could do my best to add to global warming and disrupt the biosphere and cause toxins and pollutants to accumulate, as a silly sort of revenge.  It might be fun.

I did feel less bad as the afternoon wore on and I avoided any indulgences, to the point where, near the end of the day, in idle moments, I got out Spacetime and Geometry, Gravitation, Euclidean Quantum Gravity, and even the old Thomas and Finney calculus text—the latter because sometimes I feel like I want to re-hone and improve my skills with mathematics, and Brilliant, for all that it’s a wonderful site, just doesn’t seem to work for me for some things.

I did find the two physics texts (which I opened in the middle, since I was looking for rather specific information relating to Λ, the cosmological constant) much more accessible and relatively easy to follow compared to what I was expecting.  Gravitation, in particular, is an intimidatingly large tome, but is nevertheless a bit of a “my first reader” in overall impression when compared to Harrison’s Principles of Internal Medicine.  I didn’t get very far in any of them in the time I had yesterday, but it was nice to realize that—though some mathematical formalisms are beyond my current expertise (thus the Thomas and Finney)—all of it made sense to me.  Credit the writers as much as my own cleverness, but I do give myself some credit.

Maybe I should get a biology textbook, just to reinvigorate my interest in that general subject as well.  I’m more of a literal expert in that subject than I am in GR or quantum mechanics or mathematics, though, so maybe a basic college text would be too repetitive?  I don’t know.

I’m having a bit of trouble with my laptop today; Word has frozen up on me twice this morning, which is a bit frustrating.  I suppose I shouldn’t be surprised.  I’m not sure how long I’ve had this laptop, but it’s been a few years, at least.  Ordinarily, I would think of getting a new one to replace it, but that seems like entirely too much work, and is rather pointless.  I don’t expect to write any more fiction.

The thing that led me to bring the laptop computer back with me last night was the thought of maybe at least rereading what I have so far of Outlaw’s Mind and maybe even DFandD.  I talked to my sister on Sunday and gave her a bit of a (probably rather tedious) rundown of how those stories, especially the former, interconnect with the larger universe of my books, including particularly The Chasm and the Collision, and the potential novel Changeling in a Shadow World, and other stories, all going back to the first novel I ever “finished”, back in high school—Ends of the Maelstrom—which I could probably recreate* if I had the gumption.  I certainly still know all the main characters’ names and stories and arcs and all.  I even remember my opening line:  “Horraban was happy now.”  I also remember my rather ominous ending, though not the precise words.

Many of the universes of my stories are connected to each other.  In effect, I suppose, they’re all connected via what the wizard in DFandD refers to as the “omniverse”.  I had long thought of it as the metaverse, but then Mark Fuckerberg arrogated that term to his pathetic attempt at virtual reality, and so I had to find another term.  I guess “omniverse” is actually more accurate and descriptive, but I thought the other sounded cooler.  Now it doesn’t.

Anyway, I have scads of potential stories I could write, some interconnected and some stand-alone, but I doubt that I will ever write any of them.  I just don’t have the energy nor do I have the motivation.  Merely going to work and getting back to the house uses up all the mental energy I have, and then some; much of my mental energy I need is sucked from my future, shortening my potential span of mental life as I go.

I suppose if some wealthy benefactor were to show up and offer to pay my expenses in return for getting me to write full time, I might do so.  Perhaps that could happen, but I won’t hold my breath, and I don’t encourage you to do so either.

In the meantime, though, here is the “video” from my last audio blog.  If you watch it on YouTube, please give a thumbs up, and subscribe, and share, and all that, if you’re at all willing to do so.  Thanks.

*It was 574 pages (and roughly 250,000 words, I think), handwritten on thin-ruled notebook paper, with many additions that ran into the margins, though some of these were tattered because I habitually ate paper from the edges of notebook sheets back then.  Anyway, I lost that original book when I lost all my belongings thanks to the depredations of the counties and state of Florida.  For that, I hold at least something of a grudge.
