Cosmic. Way out. I can relate.

Well, here we are beginning another Monday, and I’m writing this post—again—on the mini lapcom.

I say “again” not because I am writing this very post for a second (or more) time, nor because the last post I did was written on the lapcom, because it was not.  I mean “again” in the sense that last Monday I wrote my blog post on the lapcom.  I also did so on Tuesday and on Wednesday last week, but I cannot yet say that I will do so tomorrow and the next day.  I won’t even say “barring the unforeseen”, because I can rather easily imagine, and therefore foresee, situations in which I will not write those blog posts on the lapcom.

Of course, I also cannot predict whether, like last week, I will write Thursday’s and Friday’s posts on the smartphone.  It’s not that unlikely, but I don’t know ahead of time whether I will write them on the smartphone or the lapcom.  I could make predictions, but I think anything deviating terribly far from 50/50 would probably be very much a rectally sourced prediction.

I will say, though, that if I do write blog posts the rest of the days this week—which will include Saturday, alas—I will almost certainly write them either on the lapcom or the smartphone.  How’s that for a bold prediction?  It’s not a certainty, of course, but then again, pretty much nothing is.  It’s getting into the high 90 percentiles though, I’d guess.  I’m not skilled enough at probability/decision theory to get much finer in my estimation than that.

Anyway, that was about 250 words of utterly pointless drivel, wasn’t it?  It’s quite odd how much and how quickly I can write about more or less nothing of significance.  Mind you, from a certain point of view, nothing is really of significance.  Also nothing is of significance.  I mean two different things by those two different uses of the same words.

The first means that there is almost nothing in the universe that, in itself, is significant (cosmically speaking, of course—on different scales, significance has different requirements).  No individual, localized thing or fact can matter much on the largest scales.  On the other hand, nothing—the vacuum, absence, whatever you want to call it—is significant.  This partly refers to the fact that the universe appears to be expanding at an accelerated rate, and this seems to be due to the vacuum energy, the energy of “empty” space.  A uniform energy density in space creates a negative pressure, which creates “negative gravity” in a sense, and that drives an expansion of spacetime.

The nature of this vacuum energy, or cosmological constant, is definitely significant in that it will determine, almost solely as far as we can tell, the future fate of the universe.

Of course, the term “vacuum” may be somewhat misleading given its ordinary usage (quite apart from when one refers to the household appliance).  The vacuum is never really “empty” despite what the usual meaning of the word is.  It’s full of all sorts of quantum fields as well as the gravitational field that is spacetime itself.  The vacuum is just when these fields are in their lowest possible states/energy levels*.

There’s also the famous Higgs Field, which actually is one of the quantum fields, but it is interesting in that it is a scalar field, meaning that it has magnitude at every point but not direction (like a map demonstrating local temperatures on Earth’s surface, as opposed to one detailing the wind, which will have magnitude and direction).

If this seems a peculiar distinction to you, think of the electromagnetic field, which has both magnitude and direction at every point.  It’s actually a little more complex even than just that, because of course, electricity and magnetism are two aspects of the electromagnetic field, but each one of them is a vector field (with magnitude and direction) which interacts with the other, so the combination of them is something more involved.

Also, when energies are high enough (changing the way the Higgs field interacts with other fields), the weak nuclear force and the electromagnetic force turn out to be part of the same thing, called the electroweak force.  And, of course, there is the question of whether all the fields are really just aspects of some “higher” field or structure.

This would be some form of “unified field theory” (not to be confused with GUTs, or “grand unified theories”, which are less grand and less unified than unified field theories).  Of course, we don’t know that there is a unified field.  There may not be.  There may just be a minimum number of fields that cannot be further reduced.

If M-theory (AKA string theory) is correct, then yes, there is a unified form from which all fields derive their character thanks to the shapes and resonances of their vibrations in high-dimensional spaces.  On the other hand, other versions of quantum gravity such as “loop quantum gravity” leave gravity (AKA spacetime itself) as a separate kind of field, composed of tiny, tiny parts (the “loops”) knitted together.

At least some versions of this theory have been disconfirmed, however, because it predicts a very, very slight difference in the speed of travel of electromagnetic waves depending on wavelength, and light from extremely distant quasars has been tested and found to be uniform in arrival time (based on variability in the quasars and specific catastrophic events, if memory serves) from wavelength the wavelength, even to tiny parts in billions of light years traveled.

Okay, well, that’s surely enough trivia for anyone early on a Monday morning.  I wish I didn’t have to work today, but then again, I wish I didn’t feel like I have to do anything.  But I do feel that way.  I guess it’s probably better than being inert.  Without a goal or goals—terminal, instrumental, or otherwise—there is no action.

You can call it a “drive” instead of a “goal” if you prefer.  That may be a more accurate term, since nature doesn’t act in a teleological way (outside of thinking minds) but instead generates drives/urges/impulses, some of which lead to increased genetic reproduction and some of which lead in the other direction.  Over time, the former are the ones that tend to accumulate, for what are probably obvious reasons.

Enough.  I already said it was enough, didn’t I?  Anyway, I hope you all have a good day.  And remember, if you tend to come to this blog via other social media, you can subscribe to it using your email, and then you’ll get emails sharing every new post with you directly.

Take care.

*There is also a thing called a false vacuum.  Spacetime itself could be in such a state, if the vacuum energy is capable of tunneling to an even lower energy level than the one at which it currently resides.  This would not be a good thing for the current inhabitants of the universe, but at least they would never know it if the drop-down happened, because everything that currently exists would be erased at the speed of light.  The universe as a whole would even be affected, but it wouldn’t be endangered per se.

I almost forgot to put a title here again

I’m writing this blog post on my smartphone, as I did yesterday’s post, and in contrast to the posts from Monday through Wednesday.  I haven’t yet received any direct feedback on whether there’s a difference for the reader or what it might be, but the numbers seem to indicate that the phone-written posts are more popular than the lapcom-written ones.

This could, however, be mere statistical fluctuation, having no relation to whether readers find one or the other type of post better.  Quite possibly, most readers wouldn’t be able to tell one from the other without being told, even if the lives of their dearest loved ones were on the line.

Such is the difficulty with finding truly dispositive evidence in ordinary life.  But that’s not to say it can’t be done.  One just has to try very hard to be clear-headed and objective.  And I don’t mean “try to try” to be clear-headed, not just to be able to say “I tried to be clear-headed”, but actually to act with the true intent to be clear-headed.

Of course, the human senses and human brains gather a tremendous amount of information every waking moment, checking it against their hitherto-built model of reality, seeing if things meet expectations according to that model, and trying to improve that model, that map, of reality.  Mind you, there’s way more info in most places than anyone can take in.  That’s okay, for the most part.  Most of that detailed information is irrelevant to the life and reproduction of a far-flung African ape*.

Speaking of updating one’s models of reality, I just yesterday came across a video/written course on tensors (for physicists and would-be physicists).  The professor’s approach seems like it’s going to be a good one, so I’m planning on trying to go through the course.

I want to learn well about tensors (about which my understanding is not yet fully clear, though I get the gist of the basics) not just for my own curiosity‒which drives me, in principle, to want to try to understand everything in the universe‒but also because I will need skill in using them and manipulating them if I am to solve my longstanding point of curiosity in Special/General Relativity.

I have a specific question about what the theories predict would happen in specific circumstances, and I have not been able to find anyone who reliably answers it.  Really, no one has answered it at all, which is not too surprising, since it is fairly esoteric.

We’ll see whether I can commit to the bit.  I have a hard time maintaining focus on things for too long at once.  I dearly love to learn about new things and to develop new skills, especially in the sciences‒well, also in the arts‒but it seems that after (far too short) a time I get distracted by another interesting thing.  Either that or I just get mentally fatigued and need to distract myself, usually either with music or something funny.

I suppose that’s not really that unusual.  But lordy, it’s frustrating.  I wish I could actually want to do what I want to want to do.  Maybe I will be able to do so someday.  Maybe I will be able to devise or find more direct control of the regions of my brain which govern attention, focus, and drive.

Of course, we do have some somewhat direct ways to affect those brain regions.  The most widely used of these ways is caffeine.  The majority of people in the world use some form of caffeine on a regular basis.  At least, that was so the last time I looked.

Of course, there are other such tools, some more powerful in some ways than caffeine, but they come with their own sets of difficulties:  these include the amphetamines and related compounds and cocaine.  They can be useful in certain circumstances, but are difficult to use well, without significantly detrimental overall outcomes.

It would be easier if we could directly stimulate (and suppress) specific areas and processes of our brains at will.  Of course, the technology to do such things exists, more or less, in raw form.  One can stimulate the brain with implanted electrodes, or one can manipulate it more indirectly via externally applied electric and magnetic fields.

This has been done, of course, if only fairly crudely.  The technology I describe in Unanimity is (mostly) very real.  Is that what makes it scaaaary?

Probably not.

Okay, that’s enough for today, and for this week as well, since I am not working tomorrow (barring the truly very much unforeseen).  I hope you all have a good day and a good weekend.  Have a good meal or two while you’re at it.  Though, possibly, that’s implicit in most concepts of good days and good weekends, come to think of it.

Oh, well.  Have good ones nevertheless.

*That refers to humans, in case it’s not clear.

The name IS bond…but a double-N is more stable than a double-O

Well, it’s Friday at last, and this time, I can actually be pleased, because I don’t have to work tomorrow.

I suppose I don’t have to work any day, in principle.  I don’t have to do anything, really, if you think about it, and neither do you.  As Louis CK pointed out, if you really don’t want to do something, you can always kill yourself.  You can only do that once, but you can do it.

That was stand up comedy, of course, so don’t take it too seriously.  It’s not as though self-destruction is the only option.  One could instead just destroy the people and things that are trying to make you do something.  It would be a bit more work (ironically), but it would probably be much more satisfying*.

And it might be less work than you would think.  Most things and beings are far more breakable than they appear‒the 2nd Law of Thermodynamics is always on your side here.  And, to quote another joker (this time the Joker), “Everything burns.”

Actually, though, strictly speaking, if we’re thinking of chemical burning/oxidation such as what the Joker did to that very large stack of money, then it is not true that everything burns.  Actually, burning such as we have here on the surface of the Earth may be an extremely rare cosmic phenomenon.

It only happens here because there is so much free molecular oxygen‒it’s roughly 20% of the atmosphere (by molar concentration, I believe, not necessarily by mass, since oxygen is a heavier element than nitrogen‒each molecule of oxygen is about 8/7 as massive as each molecule of nitrogen).  The percentage of oxygen was even higher in the past for a while; that was the time when those “giant” insects lived.

But free molecular oxygen is not stable for the long term, not if there are other chemical elements nearby.

Nitrogen molecules are stable, of course (else it wouldn’t remain the majority of the atmosphere‒it would, at the very least, react with oxygen).  N2 is a triple-bonded gas molecule, with some of the strongest bonds in all of chemistry.  This is part of why so many explosives are made with nitrogen based compounds.  The separated nitrogen atoms within want to join together, and they do so with a tremendous snap, releasing a lot of energy in the process.

Think of ammonium nitrate:  NH4+ /  NO3–.  If that gets enough of a kick, those nitrogen atoms crash together violently.  Then, of course, the four hydrogen atoms bond with two of the oxygens, releasing more energy and making water.  The remaining oxygen atom probably bonds with whatever atom it next encounters, I would guess.  That’s what oxygen tends to do, unlike nitrogen, which likes** to bond with itself best.

And that is why chemical, oxygen-based fires may only exist on the surface of the Earth (and any other planet that might have evolved organisms whose metabolism releases oxygen as a byproduct).  Free oxygen tends to react with any of many, many other kinds of atoms, and those bonds tend to be very stable.  CO2, for instance, is highly stable, as are the various silicon oxides***.

Indeed, it apparently took eons for the cyanobacteria and archaea that photosynthesized on the early Earth to produce enough oxygen to become a significant part of the atmosphere, because first the free oxygen reacted with all sorts of exposed other elements, such as iron.  It seems that rust as a kind of iron “ore” may not be all that common in the universe either!  It’s prevalent on Earth because of the oxygen that floated around reacting with it for millions and millions of years.

So, anyway, what was I saying?  Oh, yeah:  instead of destroying yourself so you don’t have to work, you could instead destroy the place that wants to make you work.  On Earth, at least, pretty much everything that isn’t already an oxide (and so is, in a sense, ash) can burn, so the Joker’s claim is not entirely incorrect within the appropriate bailiwick.

Or, on the other hand, you could just…not go to work.  If your job is so repugnant to you, you could seek another job or another way of life, and you probably would not need to destroy or even harm anyone.

But that’s crazy talk; we’ll have no more of that!  This is a family blog‒it has a wife blog and two children blogs at home****.

I hope you have a good weekend.

*Actually, satisfaction is a term that probably doesn’t even apply to the dead, so almost everything would at least have a higher “absolute value” or “magnitude” of satisfaction than being dead would have.  The problem is when that vector of satisfaction is pointing in a negative direction‒then, in the number line sense, being dead would entail being more satisfied, or at least less unsatisfied.

**I’m being reckless by using anthropomorphic language here and elsewhere in this post.  There is no reason to suspect that nitrogen atoms actually like anything, nor do they appear to have any capacity to have preferences (panpsychism notwithstanding…and it is not withstanding as far as I can see).  I am speaking figuratively for the sake of being able to convey things concisely, but please don’t be misled by intentional-seeming language.  Perhaps it would be better to say that it “tends to” rather than “likes to”.  It would be more accurate, but I think most people don’t really feel how strong such tendencies can be.

***These are even more stable than the carbon oxides, and they tend to be solid at typical temperatures and pressures, which tips the scales away from the likelihood of silicon-based life.  Otherwise, chemically, silicon is much like carbon, in having 4 valence electrons, each taking up a “half” orbital, so in principle it could, like carbon, make huge, long, complicated molecules analogous to DNA.  But the solidity and density and lack of solubility it engenders would tend to get it the way.  Silicon is also a larger atom and the valence electrons are farther out from the nucleus, so the bonding strength between silicons is weaker, and they don’t form four-partner bonds as stably as carbon.

In nature’s infinite blog of secrecy a little I can read.

Hello and good morning.

I may be brief today*, because I am mentally fairly exhausted.  Yesterday was a bad day for me, pain-wise and mood-wise.  I’ve had large amounts of more than one kind of pain medicine on board, and I felt…well, I felt somewhat less pain in some places, but I’ve started to get some broader symptoms that I sometimes get when I’m taking too many NSAIDs for too long.

My thumbs and my knees and ankles and such are actually feeling wobbly and unstable as well as being generally a bit puffy and plenty sore.  This isn’t really like an inflammatory kind of swelling; that would indeed be a failure of the Non-Steroidal Anti-Inflammatory Drug(s) I take, would it not?  No, this feels more like a sense of having excess fluid in each joint, as well as in between them, and less tautness, less stability, and somewhat ironically, more pain, albeit of a slightly different character that usual.  It’s quite frustrating.

Also, my back and hips and shoulders don’t feel much, if any, better than usual.

I’ve been wondering lately if I might have some form of relatively mild hypermobility syndrome, which often goes along with ASD it seems (some of the causative genes are probably the same, or at least tend to travel together through the genome).

I have long had certain slightly atypical flexibility issues or attributes**.  For instance, I’ve always been able, with a bit of a pull, to put one or the other of my feet behind my head from a seated position.  I can also scratch pretty much any part of my own back, and I have always been able to do this, though I sometimes need to pull one arm a bit with the other.  Also, I have a hard time holding my head straight upright for very long at a time; it’s uncomfortable, and I need to lean it to one side or another pretty much constantly.  Maybe that’s just a weird habit, I don’t know.

Of course, hypermobility can be associated with various kinds of chronic pain, and can certainly make other things worse.  Unfortunately, it’s not something that can be cured, any more than autism can be cured (or any more than having a particular color of eyes or hair can be cured, though they can be masked, as by dyes or contact lenses).

I am far from sure about this tentative self-diagnosis, and I’m always leery of “second year med student syndrome”, but I think I am being reasonably objective here.  Genetic testing would be required to confirm something like Ehlers-Danlos Syndrome, but I don’t meet the criteria for full-blown EDS***, and less full-blown syndromes may not easily (nor cheaply) be testable, or testable at all.

I suppose it doesn’t really matter much.  I do not expect my baseline previous health to be recoverable in any reasonable sense.  This is one reason I’m not too terribly worried about things like heart disease and infections and so on.  Why would I want to live a longer life of the kind I now live?  It’s like asking someone if they want the massive street construction project on their block, that’s slowing traffic and making terrible noise all day and into most nights, to be extended‒not by the workers doing more improvement, but just by working more slowly and being less efficient.

At least yesterday, in between doing payroll, processing deals on an unusually busy day, and trying to discourage my body from committing war crimes against itself, I remembered and indulged in a resource I haven’t used in a while:  I got on bioarXiv and skimmed through the abstracts of some of the more recently uploaded papers in general biology, neuroscience, genetics, molecular biology, and such like.  It can be kind of fun.

I don’t enjoy it as much as I do going to the original arXiv (hosted at my alma mater), which deals in physics, mathematics, computer science and the like.  But the bio site requires less mental effort and is simpler in many ways.  This is at least partly due to the fact that I am an MD, and I got my degree from one of the more research-oriented medical schools (we were required to do a publishable medical science research project as part of our degree) so the terminology is more or less at my fingertips.  This probably would apply even more at medrXiv, at which I spend less time than the latter two.

ArXiv, the physics/maths/CS site, has oodles of interesting articles always up‒I have, for instance, downloaded a PDF of a paper by David Deutsch from there‒but most require more mental effort than on the other sites, because I don’t have as good a handle on some of the jargon, and I often need to review the mathematics involved, or more often try to absorb it for the first time.  Still, it’s very cool, though it’s a real embarrassment of riches; it’s like being in the biggest candy store in the world,  but having only three dollars to your name, and having to choose what to buy with it.

The potential opportunity costs are staggering, but I guess that’s a good problem to have.

Speaking of reviewing mathematics, I found a nice little YouTube channel by a woman from MIT who does good reviews of basic integration and more advanced techniques like integration by parts and trig substitutions and such like.  I find her stuff much less sleep-inducing than the videos on 3Blue1Brown, though Grant has oodles of great videos, well-produced and in-depth but clear, about many topics in mathematics.  Unfortunately, his voice is if anything too calm for me, and his animations, though superb, are if anything too smooth.

I think, also, that I learn better by seeing someone writing the stuff out‒possibly this engages my mirror neurons and thus makes more of my whole brain focused on what’s happening.

Incidentally, the lady mentioned above is not officially affiliated with MIT, she just went there.  But you can actually “attend” lecture courses in various subjects in Physics, in Mathematics, in Economics, in Computer Science, and so on, from MIT at their YouTube channel.  It’s truly remarkable, and if you’re just after learning the stuff but aren’t seeking an Official Piece of Paper™, it’s a tremendous resource!  Stanford also has similar online lecture courses, as I think does CalTech.

I’m pretty sure Harvard does this also, but there’s no need for any of you to go slumming there.  Why not just watch Baby Shark or something‒and Gangnam Style is actually pretty enjoyable.  I know, I know, Steven Pinker is at Harvard, and he’s one of the most enjoyable (and thought-provoking) public thinkers in the world, but I don’t think he gives any of their online lectures.

Although, given the notorious grade inflation known to be rampant at Harvard, you might just get an official “A” from them simply by clicking on one of their videos.

Okay, I’m at the stage of taking cheap shots at Harvard (they do not deserve such disrespect, even though there really is a problem with grade inflation), so I’ll call this post to a close.  I hope you’re all having a better week, year, decade, and life than I am having.  Though, really, if you’re not reading preprint scientific papers for free online, how good can your life be?

TTFN

*I was not.  Perhaps this is analogous to the situation that led to the famous quote about not having time enough to write a short letter‒only in this case, it is not time but mental energy that limits my concision.

**Some of these things are slightly curtailed now because I am too plump, but that’s a different issue.

***No, I do not refer to Ross Perot’s old company, Electronic Data Systems.

Had I but pens enough, and time…

Here we go again, again.  It’s Monday‒the last one in April this year‒and I’m writing another effing blog post.

I keep trying weird little things in the hope that they engender or otherwise encourage something positive in my life.  For instance, after briefly using a blue Bic® Round Stic™ pen on Friday, I realized that I had on some level missed writing with them.

I wrote Mark Red and The Chasm and the Collision, and the “short story” Paradox City all with blue and/or black medium Bic™ Round Stic® pens.  These were the only ones available through commissary up at FSP.  After a while, the guys who did tattoos would just give me new ones to use as long as I gave them back when empty/traded an empty one for the new one, so they could use them to make tattoo guns, and I went through such pens pretty quickly.

I thought to myself (since I have trouble thinking to anyone else*) that maybe if I started using these pens regularly again, I might help give myself the energy to start doing some new fiction writing.  So, I ordered a box of them, which is at least quite inexpensive, and I have one in my pocket now.

It’s a fairly childish notion, perhaps, but just because something is childish does not mean it’s wrong or bad.  Adults get rid of too many childish things‒sometimes on the advice of effing Saul of Tarsus of all the pathetic losers to whom to listen‒and adopt too many “adultish” things that are no more sensible, not as rewarding, and are reliably productive of negative outcomes.

Of course, some childish things do need to be left behind.  Ideally, one does not want to keep believing in Santa Claus or monsters in the closet or that stepping on a crack will break your mother’s back any longer than one must.  Wetting the bed is also worth stopping as early as one can.

But it can be good for one to keep asking questions about how things work and what they are and what they do and how they got to be the way they are, and being delighted in seeing and learning new things, and enjoying simple games and going outside and stuff like that.

Anyway, I doubt this particular choice of pens will actually get me to write any fiction again, but maybe it will at least feel good to use them again for a while.

As you know, I have at least a few stories, such as Outlaw’s Mind and The Dark Fairy and the Desperado that I have started that I’d like to finish, and I have some other stories on the back burner that I’d like to start and write.  If I could just find a patron to support me while I write, so I didn’t have to do anything else, I could probably do it.  But despite its name, even Patreon doesn’t really work that way.

People who support “creators” on Patreon pay regular, specified amounts and expect regular, piecemeal output (like daily blogs, for instance, though being the intellectually stunted populace that we are, people more often seem to want video stuff).  If I put up a Patreon, or a “Go fund me” thing (whatever the proper term for that is) I doubt that I would get a lot of people supporting me and just waiting while I work on a long form writing project.

If anyone wants to do that, and is able to do it, let me know.  Just remember, I’m slightly paranoid, so I will probably suspect some scam at first if you approach me‒unless I already know you, of course.

All of this is really just fantasizing, obviously.  I might as well request that the person who wants to be my patron for writing fiction is also a beautiful woman who is just my type (whatever that might be) and who wants to be in a long-term relationship with me.  Oh, and also, she owns a dragon, as well as an FTL spaceship.  Hey, maybe she’s a Time Lord and has her own TARDIS!

Actually, if I had the use of a TARDIS, it would probably distract me completely from writing fiction.  But I probably wouldn’t spend as much time (har) just traveling and having adventures as most of, for instance, the Doctor’s companions do.  I would want to learn how this technology works!

I don’t understand why none of the people who enter the TARDIS and gape at the whole “bigger on the inside” thing don’t right then and there ask how it works!  (Occasionally some do so, rather halfheartedly).

And when the trite little, dismissive answers such as Nardole gives are offered, they should say, “No, no, I mean how does it actually work?  What is the science and technology involved, how is it carried out and maintained?  What is the physics underlying it, how was it discovered, how was it harnessed?  Do you have any primers on that, any online courses, any textbooks, even any ‘how does it work’ for kids books?  And for that matter, how does the time stream and everything work, how is it traversed, what is the physics behind the functioning of the TARDIS?  We’ll get to the biology of regeneration in due time, but I want to understand all this.  To Hell with going and fighting Daleks or whatever, you can literally do that whenever you feel like, because you have a time machine!”

I guess it wouldn’t be a very fun show, just to watch someone studying Time Lord science and technology, but in real life, if I had access, I like to think that’s how I would spend a lot of my time.  And I think I think correctly.

All right, that’s enough stupid fantasizing for today, wouldn’t you say?  None of those or any other good things are likely to happen to me (some are far more probable than others, but none are worth betting on).

I am much more likely to keep developing new and harder to control pain and more frequently recurring and persistent pain and greater and greater frustration and despondency and depression until finally, at long last, it kills me.  Then, at least, everyone in the universe overall will be just a little bit happier.  On average, anyway.

*Though in a certain sense, this blog is an instance of me thinking to other people.  But that requires the other people to be active participants, and it certainly cannot be done all day every day or any such thing.

A pox upon those who do not learn the history of science and medicine

Well, I’m back to writing on the smartphone today, with mixed feelings.  One of these feelings is the residual soreness in my thumbs, of course, but the day-long break did seem to help a little bit.  Mind you, some of that is probably in my head, for I don’t write on my smartphone on Sundays, and I also don’t write on non-working Saturdays.  So, if resting is enough, I should feel least sore on Mondays following one of my two-day weekends.  If that is the case‒if I am least sore in those instances‒I certainly haven’t noticed.

Actually, if it isn’t the case, I haven’t noticed either, but at least there it would make sense, since there is nothing to notice.  It can be much harder to notice things that are not so than to notice things that are so.  That’s part of why people don’t give credit to vaccination, for instance:  they can’t see the sickness and death that are prevented.  There’s no It’s A Wonderful Life revelation about all the lives that have been saved and‒perhaps more important*‒all the suffering that has been prevented.

There’s a similar, lesser-known preventative effect of proton pump inhibitors (e.g., omeprazole).  These medicines (and their somewhat weaker predecessors, the H2 blockers**) have prevented untold suffering and death related to gastritis and peptic ulcer disease and esophageal cancers, all of which used to be major contributors to premature death, especially in young men (if memory serves).  So, using these medicines is not necessarily an overindulgence in avoiding transient discomfort.  They are very real and powerful preventative interventions‒though, as with all such things, they do have some long term side-effects, and these must always be weighed against the benefits of taking them.

This is one of the reasons that educating people about history is so important.  If one is not aware of just how horrifying and heartbreaking the effects of smallpox were (for instance), one might think that the smallpox vaccine***** was just a sort of convenience, not a response to a low-flying, slow-moving, global catastrophe.

I suppose it was easier for Ben Franklin to recognize that “an ounce of prevention is worth a pound of cure” because there were far fewer preventable ailments and fewer avoidable disasters back in his day.  Still, he was a very smart person; he might have recognized the nature of such things even if he had lived in our more comfortable times.

It is useful, and it may be more than just useful, for people to learn how things were before the arrival of so many powerful technologies and knowledge and social and biological insights.  For 300,000 years, humans existed without (for instance) the internet, and then, starting around 30 years ago, it was here (and widely available).

But that’s a full generation of people who have never known a world without the internet, despite the fact that by default the world has no internet.  It can be immensely useful for those people to learn about what things were like pre-internet, not only so they can truly appreciate this remarkable phenomenon, but also so they can recognize some of its detriments.

Likewise for planes and cars and televisions and even books and agriculture.  What was life like before these things?  What would life be like if they disappeared?  Are their benefits worth their costs?  How can those costs be mitigated, even if they are bearable (for why not make things as net-beneficial as possible?)?

I encourage everyone, myself included, to take these notions seriously, to think about the contrafactual cases, not to accept that things simply are the way they are, because for the most part, historically, they were not that way.  Even humanity itself is a latecomer.

I don’t know how I got onto those subjects, but I guess I’m thinking of health (and particularly of gastric health) more than typically in recent days.  I still don’t feel too well, but that’s nothing unusual for me.  It’s just annoying because it’s a new, or at least atypical, discomfort.

Oh, well.  This brings us back to my point that decreasing/preventing suffering is more important than “saving lives”, since all such saved lives are merely saved for later, if you will.  Death (it seems) cannot be forever avoided, but suffering, in principle, can be eased and even sometimes prevented.  Though, sometimes, the only practical way to stop certain kinds of suffering is to hasten the inevitable other phenomenon.

In any case, I’ll draw at least one instance of your suffering to an end now, by finishing this blog post.  I hope you have a very good day, by any reasonable measure of goodness that you might choose.

*Because death is, as far as anyone can tell, completely inevitable‒it’s a matter of when, not if‒whereas suffering is variable, and boy can it vary, from person to person, from moment to moment, from culture to culture, and so on.

**No, they don’t block molecular hydrogen***, though if one thought that, one could certainly be excused.  Rather, they block the so-called type 2 histamine receptor, the one that responds to stimulus (histamine) by making the stomach secrete more acid.

***Interestingly enough, the proton pump inhibitors do block hydrogen, but it’s not molecular hydrogen, it atomic hydrogen‒or well actually, it’s ionic (cationic, specifically) hydrogen, which is a naked proton, since a hydrogen nucleus is just a proton****, and is the key effective part of essentially all acids, at least regarding their acidity.

****Sorry about all the footnotes within footnotes, but it just occurred to me to wonder what it would be like to make a sample of an acid but with all the ordinary hydrogen atoms replaced with deuterium, so-called heavy hydrogen, which has a neutron in its nucleus as well as a proton.  How would this affect the properties of such an acid?  Of course those properties are almost entirely related to the valence electron or the lack thereof, but when a positive ion of a substance is just a naked nucleus, one cannot completely dismiss the impact of that nucleus’s structure.  So, I would love to see an entirely deuteric acid being put through its paces.  An acid made entirely with tritium (one proton, two neutrons) would be interesting as well, but even in my imagination, that’s asking for a lot of the very tiny amount of tritium in the world.

*****This is the original source of the word “vaccination” since being exposed to Vaccinia (related to cowpox) provided resistance to Variola (smallpox).

Reality, calories, and joules, oh my!

I had a moment of idle curiosity this morning just before starting to write this.  I recalled the bit of trivia that the average human power output/consumption is something around 80 or 100 Watts.  I wasn’t sure which was more typical, but it doesn’t really matter; the numbers are well within the same order of magnitude, despite having nominally different numbers of digits.

Anyway, I decided to convert that into kilocalories* per day, just to confirm that the typically described numbers match up, because if they don’t, then something very strange is going on.

A Watt is a joule per second**, so to figure out how much energy output (in joules) there is in or from a human per day, you just multiply the watts times the number of seconds in a day (24 hours per day x 60 minutes per hour x 60 seconds per minute, or 86,400 seconds per day).  Multiply that by the above-noted wattage and you get between about 6 and 8 million joules per day.

Now, there are 4,184 joules per kilocalorie, so dividing that into the number of joules yields:  roughly between 1600 and 2000 kilocalories a day, which matches the data on basal metabolic rates.  Neat.

Of course, they must match up, otherwise there would clearly be some major logical inconsistencies in our understanding of such thermodynamicalish matters.  I don’t suspect that such a mismatch would have survived the scrutiny of scientists much longer than a snowball would last in a blast furnace; in other words, I consider textbook level physics to be pretty darn reliable.  Nevertheless, it is good occasionally to check even such basic things, just to confirm for yourself that your understanding of reality is internally consistent and consistent with that which is measured and described by other people.

This is not to say that I worry about whether my “reality” is significantly different than that of other people.  I don’t.  While I have no doubt that the specific details of my personal experience are unique, this is so only in rather trivial ways.

I’ve not encountered any occurrence or argument that made me doubt whether everyone around me is subject to the same laws of physics as those to which I am subject.  Of course, if tasked or merely bored, I can conceive of ways in which all that I think I know is illusory and/or delusional, as in the argument that precedes the cogito in Descartes’s most famous (non-mathematical) work.

With a bit of effort, one can almost always imagine ways in which the world could be deeply different than it seems.  I’ve been known to do that at length‒indeed, at book length‒myself.  But the fact that a thing can be imagined is not a reason, by itself, to promote a concept into “might actually be true” space.  Presumably, there are limitless such things that could be imagined, but almost by definition (at least as I am using the word) there is only one reality.

Reality, as far as I can see, cannot contradict itself; actual paradoxes cannot be instantiated.  I’d probably be prepared to bet my life on those propositions.  But even if reality could contradict itself, that would also be a fact about reality.  Whatever reality is, it is.

That’s trivial, of course, but sometimes it’s good to be reminded of the trivial things that one carries in one’s background knowledge but rarely considers or reconsiders‒things like the interchangeability of measures of energy and power and heat between different units.

With that full circle moment, I’m going to finish for today.  I’m still very tired, and I’m rather discouraged and despondent and probably other d-words as well.  This blog is all I really do, anymore, but my energy is lagging even for this.  At least I don’t need to do payroll today, since I had to get it done early yesterday…which fact I found out yesterday.

Oh, well.  Please do what you can to have a good day.  And remember, there is no do or do not.  There is only try.

*This is what we call “calories” when speaking of human energy intake and output, but a single “true” calorie is the amount of energy (heat) required to raise the temperature of 1 gram of water 1 degree centigrade (or, well, Kelvin if you want to be pedantish).  A kilocalorie, or what we commonly call a calorie, is enough to raise a kilogram of water 1 degree Kelvin.

**A joule being the unit of energy in “SI” units.  A joule (energy) is the integral of force with respect to distance, or a Newton-meter.  A Newton is the measure of force, and is a kilgram-meter/ second-squared.  So joules have the units kilogram-(meter squared)/second squared.  Watts (a measure of power, or energy per unit time) are joules per second, which fact gives us the fun, lovely phenomenon of having cubic seconds in the denominator of the equation!

“I find myself growing fatigued, Doctor.”

Hey, everybody.  It’s Tuesday, and here I am writing another blog post.  Huzzah.

I’m rather tired today, which I guess shouldn’t be that surprising, given that I have chronic trouble sleeping.  Still, some days hit me worse than others, for reasons that are probably multifactorial and are certainly difficult to tease apart.  And today, so far, seems to be one of the “I feel more tired than usual by a noticeable margin” days.  You’ve probably all had such days, though you may not have used that specific term for them*.

There is some good news, news that in a way is not world news but is extraterrestrial news, at least temporarily:  the Artemis mission has flown ‘round the far side of the moon, and in so doing has brought humans farther away from Earth even than Apollo 13 did; this is now the farthest humans have ever been.

It’s quite momentous, but the fact of this mission and its (so far) success, raises questions.  I suspect the answers to them are disappointingly trivial, however.  For instance, why was there such a delay in returning to the Moon after the last time in 1972?  The answer to that is at least somewhat clear when one poses the related question:  why did we work so hard to go to the Moon back in the late 60s/early 70s?

Of course, the main reasons were:  primate dominance/hierarchy drives, writ large across the planet.  The Apollo program was, in a barely metaphorical sense, the ultimate dick-measuring contest, and the USA won that one pretty clearly at the time (“Mine reaches all the way to the Moon and back, how ‘bout yours, motherf#cker?”).  The fact that the Soviet Union basically admitted defeat in that region in that round is but one piece among the mountains of evidence confirming that, yes Victoria, humans did indeed land on the Moon.

It wasn’t for purely scientific reasons, though.  In fact, the science at the time took a very distant, rear-facing-storage-area-of-the-station-wagon place compared to the politics that was in the driver’s seat.

Alas, human nature being what it seems to be, perhaps truly amazing innovation and advancement is simply much more likely to occur during conflict (literal and figurative).  Maybe even the Beatles, for instance, were so great at least partly because of the (usually friendly) competitiveness between John and Paul, and also George once he found his considerable mojo.  Ringo was the Samwise Gamgee/Bodhisattva of the group, which seems appropriate for a drummer.

Humans presumably have always had the capacity to make the many scientific discoveries and technological advancements that have occurred in recent centuries.  But they needed to have an impetus before anyone would get anything done.  The two strongest inherent drives are survival and reproduction, and those drives interact and accumulate as humans gather in larger numbers, and they sublimate into national competitiveness‒for wealth and power, for luxury, for prestige, for all that nonsense.

Wouldn’t it be nice if we could deliberately control our motivation?  We have crude means of affecting it already‒caffeine and various other stimulants‒but these are blunt yet jagged tools.  In principle, microelectrodes could be implanted into something like the nucleus accumbens or the reticular activating system or more well-chosen, finely tuned areas of the nervous system.  Then one could use a remote control to give oneself motivation when desired (?).  Presumably, other mental states could be manipulated, encouraged, discouraged, etc.  Just watch out that no one else gets their hands on your remote control!

Maybe it would be better to have a helmet with various directed electromagnets to stimulate specific brain regions at will.  This process is already in use in relatively simple form**, but it could be honed and made more precise and more powerful and useful.  It would be nice to be able to have large-scale motivation that didn’t require the tendency toward large-scale destruction.

It may be an inevitable challenge.  Powerful forces can inherently have very good and/or very bad effects depending on circumstances and, of course, depending on what one means by “good” and “bad”.

Not to say that we couldn’t rather easily be doing things better than we are.  We could.  But…it seems we aren’t sufficiently motivated to do so.

*If you did, that would be truly surprising.  It would be so surprising, in fact, that if you told me it was the case, I would more strongly suspect some manner of deception or illusion or delusion or cognitive bias than that it was actually true (this is reminiscent of Hume’s test for the veracity of supposed miracles).

Is it small talk if you discuss the weather despite being alone?

Well, I brought the lapcom back to the house with me yesterday evening, but nevertheless I am writing this post on my smartphone.  Why?  Because the lapcom is more inefficient to get out of my bag and put back in my bag, and the smartphone is much easier to unsheathe and restow‒it just sits in my front pocket when not in use.  I can also use it to check the temperature, which is a bit chilly this morning even here in south Florida.  I’m sure that it’s quite a bit worse for regions north of us that have been hit by the wave of unpleasant recent weather.

I don’t find it unpleasant for it to get a bit cool down here‒55 degrees Fahrenheit* with a bit of overcast and some rain feels like autumn up north where I grew up, and that was always my favorite season.  It’s usually rather easy to adjust by wearing more clothes and moving around a bit if one feels chilly.

On the other hand, there’s not much to do about the heat and humidity other than to stay inside air conditioned buildings.  That isn’t very much fun, unfortunately, especially when one lives in a state that is touted for its beautiful and interesting nature.  After a point, though, one can take off as many clothes as one likes, but one will not get cooler; one will only be at risk for sunburn in rather uncomfortable places.

The worst part, though, is the humidity.  Yes, humans developed in sub-Saharan Africa, so we’re built well for endurance in hot environments (humans have more sweat glands per square inch of skin than any other animal).  But humidity is another matter.  Humidity is almost like an electronic counter measure to sweat’s ability to cool the body.  Sweat works by evaporative cooling; like blowing on soup, taking away the warmest liquid molecules lowers the average temperature of those remaining, and so on.

But evaporation depends at least partially on the differential in concentration between the liquid and the gas “above” it.  If the air is already saturated (or nearly so) with water vapor, there is going to be significantly less tendency for net evaporation to occur, and thus there will be less cooling.

This is why the reassuring and somewhat comical statement, “Yeah, but it’s a dry heat” is actually pertinent and indeed positive.  If the air is dry, and if they have adequate water, humans can tolerate surprisingly intense heat.  But when it’s humid, things don’t work nearly as well.

Also, when it tends to be humid and rainy a lot, one finds fungi and algae and the like growing on almost every immobile surface, as well as on some that are mobile, such as human intertriginous areas.

Anyway, to make a long diatribe slightly longer by summarizing it, I don’t mind cooler weather, but humidity is very annoying when it’s warm.

As for other matters, well, the holiday is over from yesterday, and I did not get to eat any corned beef and cabbage.  That’s a bit disappointing.  The next major holiday (which is coming soon) is the Passover/Easter holiday.  There’s no particular food related to these holidays that I like, though, nor really much of anything else come to think of it.

I did get into the St. Patrick’s Day spirit by drawing a shamrock yesterday, then scanning it and coloring it and fiddling with it a bit between other things at work.  Here, this is how it’s turned out so far:

It’s nothing terribly impressive, but it’s at least one very tiny, mild, creative act.  Not that writing this blog isn’t creative, but it’s not as creative as writing fiction, or not creative in the same way.  And drawing a picture is closer to writing a story than to writing a blog post.  Though I have to admit, at first glance drawing and writing would seem to be somewhat too different to compare.  And yet, I think I’m not the only person who has a deep, intuitive feeling that they are part of a strong, self-similar group.

It’s quite curious.  I wonder if such seemingly odd combinations are common among intelligent life forms.  Of course, if this planet is the only place in the universe on which intelligent life exists, then it’s a universal attribute of such life, if we count only creatures that use languages and create and use artifacts.

Well, this has been a weirdly inconstant blog post, especially for a relatively short one.  It’s not just meandering around among topics, it’s ricocheting.  I would prefer to meander; ricocheting seems like it would be very bad for my chronic back and joint pain.

*If it were 55 degrees Celsius, it would not be chilly at all.  Indeed, many people would be dying around here from the heat.  If it were 55 Kelvin, then, yeah, that would definitely be chilly.  Not that anyone would feel it, because we would all be dead if it were that cold.

In a better blog than this, I shall desire more love and knowledge of you

Hello and good morning.  It’s Thursday, and I’m writing this post on my lapcom.  I feel as though I ought write these posts only on the computer (not that smartphones are not computers, but cut me a little slack on this, please), and I would be more inclined to do so if Microsoft would stop making Aptos the default font!!!!!

If I could go back in time and change something, that’s one of the things I would be inclined to change.  If I found that there was one person mainly responsible for this new font, well…I don’t know if I’d go all Terminator on them and kill that person’s mother before that person was born, or kill the person when that person was a child, but something needs to be done to erase the stain of this horrible font from existence.

Certainly, if I were given* absolute power over the world, from this moment forward, one of the petty things I would do (I would try to keep the petty things to a very bare minimum, trust me**) is to eliminate that font from any and all standard computer systems anywhere.  I would probably allow for individuals to select the font if they really like it, but would not let them use it on anything but internal work between people who also like the font.

Also, I would probably mark people who chose the font freely for a visit from my secret police.

I’m kidding.  I despise the very notion of thought crime, let alone aesthetic policing in private matters.  This is even though some people’s quality of thought sometimes feels like a crime against nature.  But, of course, there cannot actually be crimes against nature.  Nature does not punish one for disobedience to its laws.  It’s simply not possible to do anything but follow them.

That’s one reason why I truly despise headlines like “The new finding by Hubble that breaks physics!” and whatnot.  Not only are they plainly clickbait, they are stupid clickbait.  I don’t know for sure if it’s just the headline writer or the writer of whatever the attached article might be who makes the headline in specific instances, but in either case, when I see headlines like that, I think that whoever wrote it really, clearly doesn’t understand physics very well.  Nor do they the nature of scientific discovery and advancement.  Because of that, I am far less likely to read the attached article (or watch the video) or even click on its link.

Nothing can break physics.  If you find something that seems to violate physics as you understand it, what you have found is not a violation of physics but rather a place where your understanding of physics is clearly incorrect.  This is far from a horrible thing.  This is how progress in physics (and in other sciences) is made:  by finding the places where our “understanding” doesn’t predict or describe what actually appears to be happening.  The world cannot be “wrong”, so our understanding of it must be, and will need to be revised.

That’s progress.

One should be hesitant to give too much “trust” to anyone who refuses to change their mind.  One of the best lines in a Doctor Who episode (not a truly great episode, maybe, but it has a wonderful speech by the Doctor) is after the Doctor has said to the “villain” (who goes by the human name Bonnie, though she is not human) “I just want you to think.  Do you know what thinking is?  It’s just a fancy word for changing your mind.”

Bonnie responds, “I will not change my mind.”

And the Doctor says, “Then you will die stupid.”***

This is simply true.  If you never learn that you were wrong about something, if you never update your credences or think about things in a new way, you will never learn anything new or develop any better understanding of the world than you did when you formed those credences.  Or, to paraphrase Eliezer Yudkowsky, if no state of the world can change the state of your retina and how you perceive that state, that’s called being blind.

I like to refer to Yudkowsky-sensei a lot, but that’s because he has said a lot of bright and interesting things, and he has said them well.  It’s also nice to know that there are some highly intelligent and thoughtful people in the world—clearly there are, or humans would long since has gone the way of the trilobites—because the idiots and the assholes make so much noise.

The best evidence I see for the fact that most people are good or at least benign (overall) is that civilization still exists, and has done so for a long time.  It is far easier to destroy than to create or even to maintain; the second law of thermodynamics tells us that things will fall apart even if we do nothing at all to break them (it says that more or less, anyway—that’s a bit of a bastardization of the proper, mathematical law, but it is related and implicit).

The fact that civilization still exists—so far, at least—seems to indicate that there must be a lot of people working to maintain and sustain and improve it, because we can easily see how much how many people seem to be trying to make it crumble****.

Assholes tend to make a lot of noise in the world, but they’re pretty much all full of shit and “hot air”.  It’s worth it to keep this in mind, because there have always been plenty of such nether orifices out there, spewing their flatus everywhere like perverse crop-dusters.  But the evidence strongly suggests that they are not the norm; they are just the noisiest.

I suppose that’s a good moral of sorts on which to end this post:  Be willing, even eager, to change your mind when warranted, and try not to let the assholes make you think the world is no better than a camp latrine (even if you’re one of the assholes sometimes, which you are, since we all are, sometimes*****).

Though, to be fair, I am hardly the person to be giving that last piece of advice unironically.

TTFN

*If you must be given absolute power, do you actually then have absolute power?  This is similar to the old song that says “Don’t ever take away our freedom.”  If you have to beseech someone not to take away your freedom, you’re not free, and if you have to be given power, your power is clearly not absolute.

**Or don’t, if that’s not in your character.  I’ve often spoken implicitly against the concept of trust, stating that I don’t feel that I can actually, truly trust any living person.  It’s calculated risks all the way down, which is empirically true if nothing else.  So, I can hardly scold someone if they don’t “trust” me.  Go ahead, form your own conclusions.  I do exhort you, though, to be as rational as possible when you form them, with your conclusions drawn as a consequence of the evidence and argument, not with your evidence and argument being curated based on your knee-jerk or at least hasty “conclusion”.
