Hello and good morning.  It’s Thursday again, and out of tradition I’ve started this blog with “Hello and good morning”, which you’ve already seen but might not have noticed.  Speaking of tradition, I’m also writing this post on my lapcom, partly for just a changeup, and partly because my thumb/wrist arthropathy has been acting up quite a bit, so I brought the lapcom back to the house with me on Tuesday evening.

Speaking of Tuesday evening going on to Thursday morning, I was out sick yesterday, and so I did not write a blog post.  I did work from “home” for a bit, because it was payroll day, and obviously I needed to get that done or else people won’t get paid.  But I wasn’t in any mood to write a blog post from the house.  I didn’t even have the energy to leave a little quasi-post like I did on last Saturday, just to let people know that I was not going to be writing the expected full post.

Honestly, I don’t feel terrific even today, but I do feel a bit better than I did yesterday, at least for the moment.  If human civilization were sane or even slightly reasonable, I would feel no qualms about taking a second day off, because no one else would expect otherwise.  But I cannot feel comfortable doing that, even if other people would not mind.  It’s a pathology, of course, but there it is.

Still, if I leave things at the office for too long, when I get back it becomes too stressful because there’s so much catch-up work to do (thank goodness, we got rid of all our mustard work long ago)*.  Luckily, I still have plenty of face masks available.  Indeed, I often consider trying to find a brand that I like and can wear every day, all day.

I’m not a fan of my face.  There are too many signs of the past 20 years or so on it.  It’s possible that these signs are things no one else would notice, but that hardly matters, because I am the one bothered by it, and I and the one stuck with this face.

It’s not an emergency.  I don’t feel like I must cover up my face, like Doctor Doom or the Phantom of the Opera or something.  It just annoys me.  Don’t get me wrong, I don’t wish I looked like someone else, anymore than I wish I were someone else.

I can’t even see how that could work in principle.  If everything about me changed into someone else, I wouldn’t exist anymore, I would be someone else.  But that wouldn’t be me experiencing the process of being someone else; it would just be someone else.  Nothing of me would come along.

I guess I just would prefer it if I could be a better version of me.  I work on it, of course; I don’t just wish for it.  I’m always trying to improve in any way that I can.  And the good and bad thing about self-improvement is that there is no finish line.  One can always be better—by almost any criterion one might choose—than one currently is.

This is similar to—and may be related to—the nature of intelligence and ignorance.  Intelligence can increase without any known limit, in principle, but everyone is always infinitely ignorant and always will be.  There is always an uncountable infinity worth of potential information one could know but does not (just within, for instance, the digits of π alone, apart from the uncountably infinite other Real Numbers).

This is a blessing and a curse, as such things tend to be.  It is a curse in the sense that one can never know everything there is to know, and therefore, in principle, one cannot know that one knows the most important things to know.  On the other hand, it is a blessing to know that one can always become smarter, more knowledgeable, than one currently is.

You can’t keep building muscle indefinitely; you can’t run faster or swim faster or bike faster without limit.  New Olympic records are set by tiny, tiny margins.  But while there surely is a physical upper limit to possible human intelligence—based upon information theory, thermodynamics, neuroscience, general relativity and so on—as far as we can tell, no one has ever gotten close to that upper limit.  You can keep learning new things every day that you are alive**.

This is a notion I wish more teachers would explain to their students.  Yes, it’s true that different people have different aptitudes for different subjects.  But unless there is real and serious pathology, anyone can get to the goal in time.  Your fundamental limits are processing speed and memory.

If your onboard, RAM-style memory isn’t great (and no one’s is VERY great) then you can store things externally, using written language.  If your processing speed regarding, say, 17^th century British literature, is slow, you may reasonably choose to do something else.  Had you but world enough and time, you could learn anything, but you don’t have world enough nor time.  In principle, though, you could learn it.

Motivation, drive, impulse is/are factors holding people back more than anything else, as far as I can see, and it’s perfectly understandable.  Thinking requires a lot of effort—fully 20% of our bodies’ calories are used by our brains***.  One wants to choose as wisely as one can just to what to apply that energy.

In principle, one cannot know for sure if one will make an optimal choice—that’s the whole “unknown unknowns” thing—but that’s part of the point of decision theory.  We have to make decisions with incomplete information, pretty much every single time.

That’s okay.  It’s much more fun to be surprised by the things one learns than just to have more of the same.  The most exciting non-personal moment in my lifetime so far was in 1998 when it first became clear that the universe was not merely going to keep expanding (rather than recollapsing) based on data in the supernova studies, but that the expansion of the universe was increasing in speed!  Literally, my picture of the whole universe changed, and it was amazing.  I cannot properly explain just how invigorating it was to learn about this.

Look at me, being slightly positive in my blog.  I must be ill, huh?  Anyway, that’s enough for today.  Presumably, I’ll be writing another post tomorrow, but I never make an absolute guarantee.

*Sorry, I know it’s a stupid joke, but I’m sick.  Please give me a break.

**And in a certain sense, you do this no matter what:  at the very least, you learn what it is to experience that day.

***Though there is reason to suspect that some politicians use a significantly smaller percentage, as do some of the people who vote for them.
