If I could write the beauty of your blogs, and in fresh numbers number all your graces…

Hello.  Good morning.

Aaahhh, doesn’t that feel better?  Now I can use my standard Thursday blog post opening phrases, because today is, in fact, Thursday.  It’s the 21st of November, the third Thursday of the month, so in the USA you only have seven shopping days until Thanksgiving.

Speaking of Thanksgiving, since next Thursday is that holiday, I probably will not be writing a blog post then.  It is one holiday on which our office is always closed.  We will be open on so-called Black Friday, but I can’t guarantee that I’ll write a post on that day.

Of course, in principle, I cannot guarantee that I’ll write anything at all ever again after this post.  I may not even survive to post this entry*‒I am in the back seat of a Lyft, on the highway (I-95) of the East Coast of the US, so goodness knows there’s a non-zero chance of a fatal accident.  I would even wish for one, but I know such a thing would involve harm and possibly death to other, more innocent, people.

Also, of course, wishes don’t actually directly affect reality‒thank goodness.  Imagine if even one percent of wishes came true as wished.  The world would be thoroughgoing chaos…and not in a good way.  I tend to say of wishes that “If wishes were horses, then we’d all be hip deep in horse shit,” but it would be even more terrifying if wishes worked.

The “if‒then” character of the wishes saying (my version or the more SFW one that involves beggars riding) often makes me think of lines of computer code in some generic programming language, like:

If wishes==horses then execute beggars.ride

Or maybe 

If wishes==horses then horseshit_level = “hip deep”

I wonder what that would look like in machine language.  Or, I wonder what it would look like in straight binary.  Really, though, I know part of the answer to the latter piece of wondering:  it would look, to the naked eye, like a random string of ones and zeros, perhaps the tally of some very long record of flipping a coin and marking heads as 1 and tails as 0 (or vice versa).

Actually, of course, given a binary-based computer language, one can literally generate every possible computer program just by flipping an ever-increasing number of coins.  Or, to be honest, one can do it just by counting in binary:  0, 1, 10, 11, 100, 101, 110, 111, 1000…

This is why, if memory serves, computer science people and information theory people say that every program can literally be assigned (and described by) a number.  You could express that number in base ten if you wanted, to make it a bit more compact and familiar to the typical human.  Or, if you want to be more efficient and make conversion easier, you can use hexadecimal.  This is easier because a base-sixteen number system is more directly and easily converted to and from binary, since 16 is a power of 2 (2 to the 4th).

Even the human genome, or any genome in fact, could be fairly readily expressed in binary.  The DNA code is a 4 character language, so it wouldn’t take too much work to make it binary, however you wanted to code it.  Then, each person’s genome would have a single, unique number.  That’s kind of interesting.

It would be a bit unwieldy as an ID number, of course.  The human genome is roughly 3 billion nucleotides long, which means it would be roughly 6 billion binary digits (AKA bits).  And since every ten bits is roughly a thousand in base 10 (2^10 is 1024, which is very close to 10^3, aka 1000) then 6 billion bits should be roughly 2 billion decimal digits long (a bit less), which is much, much larger than the famously large number, a googol**.

It’s a big number.  This should give you at least some idea of just how unique each individual life form is at a fundamental level.  There are so many possible genomes that the expected time until the final heat death of the universe is unlikely to be long enough to have a randomly created duplication within the accessible cosmos.

Of course, within an infinite space‒which is the most probable truth about our universe as far as we can tell‒one will not only have every possible version that can exist, but will have infinite copies of every possible version.  Infinity makes things weird; I love it.

Of course, just as with the making of computer programs by simply counting in binary, the vast majority of genomes would not code for any lifeform in any kind of cellular environment, using any given kind of transcription code you might want (the one on Earth, found in essentially all creatures, uses three base pairs to code for a given amino acid in a protein, but that’s not all that DNA does).  Similarly, most of the counted up programs would not run on any given computer language platform, because they would not code for any coherent and consistent set of instructions.

But even so, you would still, eventually, get every possible working program, or every possible life form in any given biological system if you could just keep counting.

On related matters, there are things like the halting problem and so on, but we won’t get into that today, interesting though it may be (and is).

It’s quite fascinating, when one is dealing with information theory (and computer science) how quickly one encounters numbers so vast that they dwarf everything within the actual universe.

Mind you, the maximum possible information‒related to the entropy‒carried within any bounded 3-D region is constrained by the surface area (in square Planck lengths) of a black hole with that size event horizon.  For our universe, roughly 96 billion light years across, I think that’s something like 10 to the 124th bits, or at least it’s that many Planck areas.  That’s quite a bit*** smaller than the number of possible genomes, though I have a sinking feeling that I’m underestimating the number.

And information, at least when instantiated, has “mass” in a sense, and the upper limit of the amount of information in a region of spacetime is delineated by the Bekenstein entropy description.  So there’s only so many binary strings you can generate before you turn everything into a black hole.

Something like all that, anyway.

I may have been imprecise in some of what I said, but when you’re dealing with very large numbers, precision is only theoretically interesting.  For instance, we**** have found Pi to far more than the number of digits needed to calculate the circumference of the visible universe down to the Planck length.  It would require only about 40 digits of Pi to get to that precision to the size of a hydrogen atom, and those are only about 10^25 Planck lengths across, so we wouldn’t expect to need much more than 65 digits of Pi to get that precise, but let’s be generous and use 100 digits.

How many digits of Pi have actually been “discovered” by mathematicians?  Over 105 trillion digits.  Talk about angels dancing in the heads of pins!  It’s literally physically impossible, according to the laws of quantum mechanics, even to test whether that number precisely defines the ratio of any given circle to its diameter by measuring it.  One cannot, in principle, measure finely enough.

Still it just goes to show that mathematics is vastly larger in scope than any instantiated, superficial reality.  Information is deeper than one might think…so to speak.  But, then, so are minds themselves, vastly deeper.

As Idris/the TARDIS asked in Doctor Who, Series 6, episode 4, “Are all people like this?  So much bigger on the inside?”  Yes, Idris, I suspect they are, even those people we don’t like and feel the urge to denigrate.

That’s enough for today, I think.  I’ve achieved nothing, really, other than write a Thursday blog post, but then again, that’s all I meant to do.  I hope you have among the better half of all the vast number of possible days available to you.

*If you’re reading this, though, I clearly did survive.  I have mixed feelings about that.

**How much larger?  Soooo much larger that if you subtracted a googol of something from 10^1,800,000,000 of something, you would not change it to any extent measurable even by the most precise instruments humans have ever created.  And a googol is already something like 10 to the 19th times as large as the total estimated number of protons and neutrons in the accessible universe.

***No pun intended.

****Actually, I had nothing to do with it; it’s just the sort of “royal we”***** kind of thing everyone uses when discussing the accomplishments of humanity as a whole.

*****Not to be confused with royal wee.  That’s the sort of weird, niche thing one might find for sale in mason jars on the dark web.  Be careful if you’re into such things.  I wouldn’t buy it unless you’re sure of the source, so to speak.

It might be the pate of a politician, which this blog now o’erreaches

Hello and good morning, o dedicated reader(s).

I honestly don’t feel very much like writing today‒I feel extremely low even for me, very gloomy, very pain-riddled and dysthymic, my mood made worse by the diminishing daytime in the northern hemisphere‒but since I did my little throw-away non-blog last Thursday, I figured I might as well do something today.  I don’t know if anyone truly looks forward to my blogs‒it’s hard to imagine someone’s day being worse because they didn’t get any input from my thoughts‒but just in case someone does, I will write.  Or, rather, I am writing.

I don’t want anyone to think that my depression is unusually bad due to political events, and certainly not for anything parochial, provincial, local in time and space.  Cat forbid!

I’m sure that people throughout history have thought that whatever local politics was happening just then, at that moment, was Earth-shattering and of monumental importance.  But, of course, as Ozymandius reminds us, all the great people and events of the past, all the presidents and emperors and warlords and whatnots, are but headless, trunkless, disintegrating statues in a featureless desert.

Actually, most of them are never even that.  During the Cold War, admittedly, especially the latter part during maximum arms race and belligerence between the US and the USSR, it was possible for politics to engender the destruction of much of civilization (and I truly didn’t think the odds were good that we would avoid thermonuclear war for very long*) but even then the moment-to-moment politics was almost incidental.

The Cold War and its existential dangers lasted through numerous presidents and premiers, the former of various political parties‒Truman (D), Eisenhower (R), Kennedy (D), Johnson (D), Nixon (R), Ford (R), Carter (D), Reagan (R), all the way up to George H. W. Bush (R).  And, of course, on the other side, we had Stalin (C), Khrushchev (C), Brezhnev (C), Chernenko et al (C), and Gorbachev (C).  One might imagine that Bush, Sr. and Gorbachev would be truly celebrated historical figures, given their leadership positions at the end of the Cold War, but I don’t see a lot of evidence thereof.

Now, political stupidity** has, of course, caused havoc locally on many an occasion.  More people were killed thanks to the ideological idiocy of Stalin and Mao, for instance, than were killed in wars in the 20th century, despite the immensity of those wars.

But, of course, nearly all the people who died in and around the first world war at least (and most of those alive during the second) would have been dead by now, anyway.  And certainly, everyone who died unnecessarily during the French Revolution and the Napoleonic wars would definitely be dead by now, whatever might have happened.  And all the people slaughtered by the hordes of Genghis Khan would be dead now, no matter what.  And certainly anyone killed due to the mismanagement of even the worst of the Caesars would be dead now‒as dead as Julius Caesar, as they say.  And the people of Greece and Macedon and “Asia Minor” and Egypt and Persia and all those other areas would be dead now whether Alexander the Great had conquered his known world or not.

I recall a column that Michael Shermer wrote in Scientific American (back when it used to be worthy of his writing) called “Remember the 6 billion” (roughly the population of the world at that time).  His point was that, within the following 120 years at most, every single person then alive would die…and for the most part it would go entirely unnoticed, because new people are constantly sporulating to take the place of the ones that fall by the wayside.

The “Great Men” (and women) of history are mostly just names and caricatures; they have no effect on the long term structure of civilization.  We recall that Alexander was a brilliant military leader‒an artist in that realm, perhaps‒but his contributions to that field have no major bearing on modern life.

The ideas of Archimedes, for instance, have had much more durable effects, but that’s because they are discoveries about the nature of the universe, of reality and its underlying rules or tendencies, and so they are, in a sense, universal and universally discoverable by any intelligent civilization anywhere in the cosmos.  Ditto for Galileo and Newton, for Maxwell and Einstein and Schrodinger and Planck and their compatriots.

Not that we should not celebrate those achievements and discoveries, but they are in some senses nonspecific to any individual.  Even the work of Darwin, which may seem both specific (har!) and provincial, since it refers to life on Earth, is probably at least as universal as the work of Newton or Dirac or even Emmy Noether.  Natural selection applies to numerous things even within the higher orders of civilization‒languages, political systems, forms of transportation, the durability and character of bureaucracies, etc.  A form of it may apply to the formation of planetary systems and the potential origin of life therein, and even to the possible bubble universes of the hypothetical inflationary multiverse (or more specifically in Lee Smolin’s speculative notion of universe natural selection through black hole related cosmogenesis).

But politics‒well, it’s provincial in pretty much every way.  Can you imagine any truly alien race caring who got elected president or which party ran the poorer campaign, why one did better or the other worse?  Go canvas the dolphins for their opinions, or the octopuses, or the corvids, or ask a beehive or a termite mound or an ant colony.  Try to get them to give flying fuck at a tiny little that’s ass*** about the minutiae of human politics.

No, my depression, like my pain, is endogenous, or at least it is not trivially reactive.  It is always with me, a truly dark passenger (who often takes the wheel).  It’s probably a product of my atypical, alien neurology, but of course, I’m not anything like as alien as a cephalopod or hymenopteran or a cetacean.  I’m just humanlike enough to exist in the uncanny valley:  weird enough to be unsettling, but not weird enough to be interesting or cute or “beautiful” because of it.

So go ahead, catastrophize or hyper-celebrate about the latest political farce, not recognizing that a lot of what went wrong on all sides was that very tendency to demonize, to catastrophize, to overreact and to be self-righteous.

There is a saying that came into prominence sometime in my teens to twenties (I don’t recall the first time I heard it).  I initially found it irritating just because it was such a “new thing”, but I think its message has endured and even grown in value:  get over yourself.

Everyone needs to take this admonition to heart.  We are all just virtual particles, not-quite-really-real bosons that can carry some degree of information or “force” when there are enough of us around, but which all ultimately pop back out of existence before our presence can even really be noticed by any outside observer.

That’s okay.  It had better be okay, because it’s not optional****.  And if that state of the world, that nature of reality, is unnerving to you, don’t mind it too much.  It won’t trouble you for very long.  No one here gets out alive.

TTFN

*We still haven’t avoided it for very long.  It’s only been a danger for about, what, 70 years?  Really, it’s a little less than that since we’ve had truly civilization-ending amounts of sufficiently powerful nuclear weapons.  So, since I’m just now 55 years old, the threat of global thermonuclear war is only about a decade-ish older than I am.  It could almost be thought of as my eldest sibling.

**Redundant?

***I would not put it past dolphins to try such a thing.

****It’s a bit like free will:  You either have it or you don’t, but you don’t have any choice in the matter.

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

Good-o and hell morning.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

We’ll see, I guess.

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

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

TTFN

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

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

And writers say, the most forward bud is eaten by the canker ere it blog

Hello and good morning.

It’s Thursday, so it’s time for my Thursday blog post.  There will be no fiction from me today, other than such ordinary, day-to-day fiction as pretending to be doing better than I really am, as well as using money to buy things*.

I’m writing this on my phone, since I didn’t bring the laptop computer back to the house yesterday.  I was wiped out, and stressed out, and I didn’t feel like carrying any more than necessary.  I did get a bit of walking in, since I had to stop at the store on the way back.  I guess that was good, though something in the way I moved caused a blister on the medial side of my right big toe.  It’s not too bad, but I’ll probably not do any serious walking today.

It’s often questionable why I bother.  Of course, I would like to lose weight and whatnot; I would rather not die the physical travesty that I currently am.  But the best way to do that would be to stop eating completely.  That would be a win-win situation, as the cliché goes.  But that is very difficult to do in ordinary, day-to-day life in the modern United States.

I got a terrible night’s sleep again last night.  It wasn’t as bad as my one-hour night earlier in the week, but it wasn’t a whole lot better.  I’ve been trying to restrict my caffeine intake to the relatively early morning, just to make sure that doesn’t interfere with my sleep, but it doesn’t seem to make much difference.

I haven’t read anything much in quite a while.  I think it’s been over a month since I read any book, fiction or nonfiction.  I have been doing some stuff on Brilliant dot org, as I’ve mentioned here, but yesterday I didn’t even feel like extending my “streak” by doing some simple work in their computer programming course.  For one thing, the constant prods to “extend one’s streak” are thoroughly irritating.

I really despise all the manipulative tactics undertaken by these companies to get people to keep using their sites.  Even Kindle does it.  I had a “streak” of something like 170 or more weeks of reading pretty much every day on my Kindle app, but that’s now been broken, and already Amazon isn’t even recommending any e-books to me.

Still, it’s not as though I ever read to maintain a “streak”.  I read because I want to read.  Except right now I don’t.  I don’t even want to read my own stuff.

I did practice a little on the guitar yesterday.  I guess that’s something.  And, as you all know, I’ve been writing fiction now for a total of over twenty days (counting only writing days).  But it feels almost disloyal to be writing without reading, though it’s only myself that I’m betraying, and I don’t like myself, anyway.  Still, reading has been a fundamental part of my identity for literally as long as I can remember, and not being able to do it makes me feel very much adrift and puzzled.

It’s getting seriously hot and muggy down here in Florida.  I’m sweating significantly and quite visibly just sitting at the train station.  I suppose, if climate change persists, Florida will at least reap what it has politically sown, since both the heat and the sea levels are likely to drive quite a lot of people out of the state, and make much of the coveted ocean-front property into literal and figurative underwater real estate.

I’m not the sort to laugh in malicious glee when people get their comeuppances; I’m much more the type to tighten my lips grimly and nod in affirmative contempt.  But that doesn’t mean it’s not ego-syntonic for me when people get fucked over because of their own arrogant stupidity.

I don’t expect to be around to see any of it happen.  And, honestly, I would not be disappointed if people actually make headway at fixing the problems and correct them in time to save even people who don’t necessarily deserve to be saved, because innocent and beneficent people will be saved along with them.

Human ingenuity is much rarer than people probably think; however, it is so incredibly powerful that it doesn’t take much of it to accomplish wonders.  I guess it’s worth it for there to be so much arrogant stupidity if that’s necessary or unavoidable in order for the occasional sparks of cleverness and even genius to be found.  But it would be nice if stupidity were more sexually unappealing than it is.  Regrettably, though, stupid people seem more likely to breed than smart ones, especially since the smart ones understand about planning and delaying reproduction, or even choosing not to reproduce at all.

Oh, well.  This is the tragic farce of life.  It can be funny if you like lowbrow slapstick in the vein of the Three Stooges.  Unfortunately, I’m not really a big fan of such things, so I don’t think I’m going to keep watching much longer.

All right.  Time to call this to an end.  My back is flaring up quite a lot, probably from yesterday’s walk, and it’s distracting me.  Please try to nurture cleverness and creativity at all levels, and please don’t feed the trolls in any sense.  They’re not worth it.

*Yuval Harari famously pointed out that money is a “fiction”, though it is a useful and important one.  So is law and government and the very existence of rights and stuff like that.  Such things exist only in the minds and works of people.  Nature certainly recognizes no rights, unless you want to count the right to be wiped out if you don’t do what you need to survive.  Indeed, the world seems to promise only one thing:  eventually, you (as well as everything you would recognize as the universe) will die.  That’s probably a truly unalienable right.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Complexity theory is still a very young science.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Have a good week, if such is your destiny.

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

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

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

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

The moon may be a harsh mistress, but her eyes are nothing like the sun

I was going to write this post on my laptop computer, since I had brought it with me back from the office on Friday, thinking to write fiction this morning.  However, I am waiting for fares to go down to normal levels for Uber or Lyft this morning, so while I wait, I figured I might as well write this post on my smartphone.  It’s inconvenient to write on the laptop computer while waiting at the house, because to do so I need to set up a TV tray table type thing.  That’s not hard, of course, but it’s still more effort than I mean to put forth for something that will hopefully only entail a few minutes’ delay.

I should just have gotten up when I was awake‒well, okay, not when I was first awake.  There would be no point in going to the office in the literal middle of the night.  But if I had gone to the Tri-Rail station early enough, I might have gotten on the 4:20 train.  Still, who knows?  Maybe Uber rates were twice as high as usual even then.  I don’t know why the ride services are so busy at this hour on a Monday morning.

Whatever it is, I don’t see how it could have anything to do with the eclipse that will be coming today.  That phenomenon is cutting a line from the southwest to the northeast across the country, including up by my sister’s house.  I won’t be seeing it, of course, since I’m down here in south Florida, and there won’t be another opportunity to watch one in my lifetime from anywhere readily accessible to me.

I could have gone; I was invited to visit by my sister.  The people at work thought I should go.  But when I started looking into booking either buses or trains or planes‒even though I did renew my state ID to make things easier‒I felt tension bordering on dread at the prospect of traveling in any of those ways.  So I didn’t go.  And here I am.

***

Ride rates have now dropped to normal, and I’m outside waiting for my Uber.  I was hoping to be able to ride my bike to the train station; I changed up my upper body workout a bit last week, and it felt different enough that I thought I might be able to use the bike without issue.  I rode it a decent distance on Saturday, with minimal trouble, though I felt a bit stiff overnight.  Then I rode it some more yesterday, and while riding I felt fine.  I even felt rather good, if slightly breathless.  But then, overnight, the stiffness and splinting and spasms started up again, so I fear that’s just not going to work.  I also have soreness in my right Achilles tendon and significant pain in my left knee, and my left side feels like it’s been infused with hot metal.

***

I’m at the train station now, still in pain (of course) and seated on the ground because I was too late because of the Uber delays to get a good seat where I prefer to sit.  It’s annoying, but I guess I would have been even later if I had ridden my bicycle.  Then again, at least I would have had the good feeling of having gotten some exercise.

Oh, well.  I don’t know whom I think I’m fooling.  I don’t expect to get back in good shape any time before I die.  Every time I try to exercise (so far) it screws me up with worsening of my chronic pain.  I wish I could just shut the pain off, but biology is not readily amenable to compromises in that area.  Pain, like fear, is too essential.  All things that suppress either of them‒even when the pain and/or fear have become thoroughly dysfunctional‒cause terrible side effects.

I can’t go on much longer like this.  It’s almost too bad that the solar eclipse is not some harbinger of disaster, but of course, it is not.  It’s merely a consequence of the geometry of three bodies whose mutual orbits lie nearly in the same plane.  If the moon’s orbital plane were identical to the Earth’s around the sun, there would be a lunar eclipse and a solar eclipse with each orbit of the moon, and predicting such things would have been far less impressive to the native peoples of Hispaniola when Columbus used his knowledge thereof to dupe them into going along with his plans.

Some modern people seem barely less credulous, despite being avid users of the Internet and World Wide Web.  Why, the leading independent candidate for president is full of ideas so absurd that they would have been rejected as plot points in the later seasons of the X-files.  If you caught him at the right time, you could probably convince him that early vaccines had been used to mind-control him and that he had assassinated both his uncle and his father.

Sorry.  I’m grumpy.  My apologies.  I’m in a lot of pain‒more so than usual‒and of course my sleep has been horrible, though at least I napped some over the weekend.  I also replaced the shower-head in the bathroom, but that’s not very impressive, and I had the cable people out to replace the modem for the Wi-Fi, but though that was absurdly nerve-wracking, it’s hardly a big accomplishment.

I feel horrible and rotten and disgusting.  I wouldn’t give myself 5 stars even on an Uber or Lyft scale (in which, if someone doesn’t get 5 stars the app asks you what went wrong, but only gives you pre-programmed, simplistic options for explanation, eliminating the whole point of a 5 star rating system‒3 stars should be the average, but instead it’s something like 4.9).  I wouldn’t give myself an A even on the Yale grading scale (in which, it seems, the vast majority of students get As in the vast majority of their classes‒again, destroying the whole point of the grading system and eliminating any incentives to excel).

Maybe I should write a whole post about that issue, how (among other things) grade inflation makes the prestige of elite educational institutions evaporate, since in the real world, business is competitive, and a 4.0 from a school where everyone gets a 4.0 and there is no merit-based admission will gradually (but not necessarily slowly) come to be not worth the virtual paper on which it is written.

Again, I’m sorry.  I really don’t feel well at all, and I don’t feel good at all, either*.  I hope you all feel significantly better than I do, physically, emotionally, morally and otherwise.  I’m sure you all deserve it more than I do, though “deserves” is for the most part a vacuous term.

I hope you all have a very good day.  If you get a chance, and are in its path, observe the eclipse (but don’t do it directly, not with unprotected eyes).  It’s not an especially impressive cosmic phenomenon, but it’s still pretty cool.  It’s particularly cool that the human race understands the universe well enough that these phenomena, which confused our ancestors so mightily, are almost banal to us, and we can predict and plot them out centuries in advance.

It’s particularly uncool that despite how much is known and understood, there are people who live in the modern world and who constantly use devices that rely on quantum field theory and general relativity yet still think a solar eclipse might be some supernatural sign.

Heavy sigh.  What can you do?  The world is tragically comical and comically tragic.  It’s probably not worth the effort.  And I’m darn near sure that I am not.

*Yes, I mean two different things by those two words.

Would YOU eat Zel’dovich pancakes for breakfast?

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

I will probably be writing here tomorrow.

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

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

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!
