It’s Friday, and I’m writing this post on my mini laptop computer, because although yesterday I forgot it and had to use the smartphone, it was really quite nice the other day to be able to type for real and not tap around on some simulated keyboard with no aesthetic appeal, on which one cannot feel the keys responding to one’s touch (and which gives this one arthritic pain in the base of his thumbs).

I remember when the notion of such a virtual keyboard first appeared to me—this was in Star Trek: The Next Generation.  I thought the idea seemed terribly unsatisfactory despite being very clever.  I mean, I recognized the efficiency of it, but when the characters would read books and such things on their little portable “tablets”, it seemed almost heartbreaking.

Obviously, in a star ship in deep space, they’re not going to have room for a vast physical library such as the virtual one they clearly have in the ship’s computer.  It’s much like the fact that I have many more books in my Kindle library than I have in my physical living space (though I used to have way more physical books than I have current Kindle books).  But something is lost a bit, nevertheless, at least for me, with such virtual collections.

Actually, it just occurred to me:  in Star Trek, they use replicators to make their food and so on, applying the transporter technology to reproduce scanned items that include food.  Why could they not use that to replicate books as needed, then scan them away when they were done?

Of course, the quantum mechanics of potential real world transporter-type technology is such that you couldn’t mass produce anything from “scanning” any one particular item; as part of the required entanglement process for quantum teleportation, one destroys the quantum states of the particles in the original item (or person, if it’s a person, so Dr. McCoy was right to be leery of the transporter).

Also, the entangled particles used to reconstruct the item by creating a new set of particles in identical quantum states to the original, could not be kept in their transitional states indefinitely; such states are not inherently stable.  Even if they could be maintained thanks to advanced technology, once they were used to recreate the original item or person, those entangled particles would also have their own quantum states irreparably altered, and could not be used to make another copy.

You can never make more than one copy of a thing sent by quantum teleportation, The Enemy Within notwithstanding*.

Still, maybe the people in TNG could “scan” a bunch of real books, as if about to transport them using the ship’s transporters, and just…save them for later.  You couldn’t make multiple copies, again because the originals would not still exist after being scanned—as I noted before, such scanning destroys the initial quantum states of all the constituents of the scanned item (or person).  But they could just be singly stored in the “buffer”, saving the quantum state of the entangled particles used to apply quantum teleportation.

But wait, I hear you say, storing all those books “in transition” would entail a tremendous amount of stored quantum information that would need to be maintained in its entangled state indefinitely, at presumably great cost in data and energy.  Not only that, one would have to have the equivalent of the mass of those items in the ship at all times, no matter** what.

You are very clever, and you are, of course, correct; it wouldn’t be efficient in any sense, and would add to the power requirements of the ship.  Also, in any serious disruption of the ship’s stability and power—such as happens in nearly every episode, so more than twenty times a year on average—much of that quantum information would probably be lost.

Maybe it really doesn’t make practical sense to try to do such a thing.  After all, I’m the person who has bemoaned the incredible data wastage necessary to store audio, let alone video, files rather than the much more efficient written word.  And I have not changed my mind on that set of subjects.  I could record a video, or even an audio, of me reading the words of this blog post, and it would have a file size in the hundreds of K at least; for a video, it would probably be many megabytes in size.

Meanwhile, my average blog posts, as stored in Word, are 16 to 20 K in size.  It’s quite a difference.  Even just using the RAM of this small computer (4 gigabytes) I could load up as many as a quarter of a million blog posts (assuming nothing else were in the random-access memory, which in not the way things work).  That’s about 250 million words.  Even I am unlikely to write that much during my lifetime.

More importantly, with the written word no one has to look at my ugly mug (though I will admit that my voice is absolutely lovely, so it might be worth hearing any audio file I produce…Ha-ha, just kidding).

Anyway, as I noted, it’s Friday, and I’m almost certain we’re not working tomorrow—I’m inclined to say that, even if the office is open, I’m not working tomorrow, but I tend not to follow through on such ultimata, because I’m a pushover—so there won’t be another post until Monday, at the earliest (barring, as always, the unforeseen).

I hope you all have a good weekend, but at least I know, as I pointed out yesterday, that you will have the best weekend you possibly can, since whatever happens becomes inevitable as soon as it happens, and it may have always been so (if quantum superdeterminism is correct).  Of course, that means you will also have the worst weekend possible.  But for most weekends, that’s a comfort.  For most such weekends, you could honestly say, “Well, if that was the worst weekend I could possibly have had, it’s not so bad.”

Usually, you could honestly say and feel that.  And it’s very likely that this weekend will be one such usual weekend.

Have a good one.

*In any case, that episode is really more of a fable than anything truly science fiction.  It assumes a bizarre kind of dualism between body and mind and a further, cleanly divisible dualism even in the mind itself, which in the episode is split into discrete but very broad personality aspects that can be separated out into different bodies.  It’s an interesting exploration of the tension between aspects of a person’s character, and engages speculation about whether a dark/violent side is a necessary aspect for a good leader.

**No pun intended, but I’m leaving it.
