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.
