On the Paradoxical Nature of a Perfectly Inflexible Body

... of Finite Non-Zero Mass and Non-Zero Temperature
[Note:  I had another name in mind, but, on checking my terms, it seems that "perfect crystal" and "ideal crystal" both refer to crystals without imperfections, rather than perfectly rigid ones.]
[Note:  I've had this idea in my head before, but I've never gotten to writing it down before.]
We consider the possibility of the existence of a real object with zero flexibility (or infinite rigidity).  However, rather than using math and formulae, we use logic and the overall concepts that have been known in physics for some time.
Suppose that it is possible to construct a perfectly inflexible crystal one lightyear in length and symmetrical about the plane perpendicular to this axis and bisecting its center point (such as a cylinder).  Note that, in this case, we are ignoring the thermodynamic difficulties in removing all heat from an object - we soon won't need them.  Supposing, then, that we set up monitoring stations on either end of the hypothetical object, and assuming that it will tend to pivot about its center of gravity, any movement applied to one end of the object would be immediately detectable (though in the opposite direction) at the other end.  This would entail the travel of information one lightyear in zero time, in violation of relativity.  Note that, even if we somehow hold it at the far end, the movement then becomes detectable half of one lightyear away in zero time, which poses the same problem.  (Technically, the movement is detectable in many other locations (i.e., all or nearly all points along the structure), but these ones are a bit more illustrative.)
Consider, though, that any non-zero distance poses a problem, since the speed of information travel would still be infinite.  Thus, even a perfectly inflexible crystal only three atoms in length would create a contradiction against relativity.
Note, though, that the argument outlined here applies only if there is energy in the system of the perfectly inflexible crystal, such as that applied by the movement of one end.  However, completely removing energy from the system is a difficult prospect, as it may entail, among other things, removing gravity from the universe.

Sudden Short Story 5

"...All of these precautions... How did anyone ever assemble an electronic computer without breaking something?"
"Well, back then, electronic computers were consumer appliances, just like optical computers are now. Most people bought them pre-assembled off the shelf and never even cracked the case. They worked well enough for however long, and they were replaced regularly.
"It's funny, actually. You see, electronic computers had gotten to the point where they were all laptops, at least off the shelf. The only large form-factor ones were those assembled by hardcore gamers, and they ended up being the first consumer base for optical computers. Nobody else could justify the large form-factor, and most computers for personal use didn't need the speed boost at that point."
"So we have gamers to thank for modern computing, eh? How about that. So, do you like all forms of alternate computing, or just this one?"
"I think that I just like old things. You know, I'm thinking of building a mechanical computer after this. It should be even more interesting: Apparently, they never achieved commercial production before electronic computers took over.
"I dare say that it must have been a terribly interesting time, back then. Even electronic computers could fill entire rooms, and had to be serviced by large staffs...."

There's a Crack in my Beast Below

Right, I meant to blog about this quite a long time ago, but I forgot.
There's sort of a bit of an enormous plot hole in the Doctor Who episode "The Beast Below". Fair warning: There are spoilers regarding this episode of Doctor Who. Also, I'll probably talk as though you've already seen the episode, so it would be good for you to watch "The Beast Below" before reading this, if you haven't already.
So, at the end of "The Beast Below", it is discovered that the titular character (the beast below, not The Doctor), who has been propelling the giant city-ship up until this point, goes faster when it's not being shocked in the brain every few seconds. Specifically, the creature came to Earth in order to help the humans, though it couldn't communicate with them, which is supposed to have allowed this whole scenario to emerge.
To make sure that we're on the same page here: for literally the entire journey of the vessel (a few centuries in length), the beast below the city has been being shocked, in the brain, at very regular intervals. This is where I see an enormous plot hole. It means the following:
-Whoever was in charge of this project had to, somehow, decide to start shocking the alien in the brain once every few seconds before they left Earth orbit.
-Whoever was in charge of this project had to then implement this shocking plan, including making the brain-hole and constructing and activating the probe, again before leaving Earth orbit.
-The probe had to go the entire trip without breaking, needing replaced, or needing to be turned off to be cleaned, repaired, or updated.
-For the entire trip, the probe's power supply had to be uninterrupted.
-They had to never want to stop or slow down. Since they thought that the frequent shocks were keeping the beast moving, they would have reduced or stopped them to slow down or stop.
-Nobody ever said "Hey, what do you suppose would happen if we stopped shocking the creature for a few minutes?" - at least not in a convincing way.
-Nobody ever accidentally turned the device off.
-No scientist in the control room ever went rogue enough to sabotage the shock system. Also, nobody ever successfully broke into the control room or hacked into the controls to do the same.

Basically, the decision to set up this shock system was extremely unscientific - grounded only in ... well, absolutely nothing - and keeping it in perpetual operation would be a logistical nightmare - as anyone who has to maintain any system can tell you.

P.S.: I'd have given more/better details, but I'm going on memory, and the episode was quite a while ago. Like I said, I meant to blog about this and forgot.

On Squirrel memories

I had an idea just now. I remember, in the past, when I was younger, hearing stuff about how squirrels bury lots of acorns, etc., but only dig up a few, and presumably forget where many of them are buried. I've devised an experiment.
Let's say that we have a population of squirrels that typically digs up 30% of its buried nuts. The experiment would be to dig up half of a given squirrel's buried nuts when it's not looking (do squirrels hibernate?).
We fully expect the squirrel to dig up some spots where it originally buried nuts, and find them missing.
If the squirrel successfully digs up only 30% of the remaining nuts, then it probably only remembered 30% of the original.
If the squirrel successfully digs up 60% of the remaining nuts (or twice whatever its original percent was), then it probably remembered all locations, but only needed a certain number of buried nuts.

Experiments about this have probably already happened, but I just happened to think of it, and I haven't been blogging enough!

The Doctor is Human

I've thought about this before, and yesterday, I figured that I should blog about it. The Doctor, from the SF show Doctor Who?, is human.
"But wait," says everyone who knows anything about Doctor Who?, "The Doctor is a time lord." You are correct*, and the time lords are human. It seems most likely that the time lords are the result of the evolution of an isolated human population. They seem morphologically and physiologically so similar to humans that their arising completely independently of Earth's biology would have to occur astronomically improbably. And, of course, being evolved from humans means that they are humans.
Let's compare and contrast. On the one hand, time lords have two hearts** and can regenerate. On the other hand, time lords are bipedal plantigrade pentadactyl tetrapods with opposable thumbs, fingernails, two forward-facing color-vision eyes set in closed ocular orbits in skull-enclosed heads with hinged jaws bearing white, bony teeth, pink, fleshy tongues, and soft, pliable lips, altogether capable of speaking human languages, ostensibly with the assistance of vocal chords. They also ingest food through this forward-facing face-holes and apparently have taste buds, too. Time lords also have fleshy, dish-shaped ears on the sides of their heads, hair that grows out of the tops of their heads, along their eyebrows - and, by the way, eyebrows - and reduced or absent hair elsewhere. Also, time lords have skin in that variegated sepia range (dark brown to pale peach-ish) that humans have, as opposed to, say, green or orange. Oh, and time lords can be killed by untreated cyanide poisoning.

That's basically my argument for why the time lords are human. There are other things, but I haven't actually seen proof of them. For instance, I'm assuming that time lords have spinal chords enveloped in vertebrae, which would make them chordates and vertebrates, respectively, but I haven't actually gotten a look at The Doctor's back well enough to tell if there are vertebrae there, so I didn't list them above.
Anyway, if you see anything that I should have included in my lists, then leave a comment below, but, more importantly, if you see someplace where you think that I might be wrong, then leave a comment below.
That's all for now.

*as long as you didn't add a clause asserting that The Doctor is not human
**The fact that time lords have hearts is a similarity, by the way.

Sudden Short Story 2

Victor Kurzweil - no relation - was an out-goer. The last of a dying breed, he actually spent some time wholly in his body. Of course, he always felt that he left a bit behind whenever he "wandered out of the mists", as the latest notion was - "notion" being the new "meme", after all.
At this particular time, Victor left. He went out. He stood his body up, which was possible for anyone, since solutions had been found long ago to prevent the meat's meat from atrophying, but was slightly easier for out-goers, since they actually used it. One of the odd things about meatspace - "meatspace" being a very old and classical term, like "water" or "the" - was the lack of sensory input. There weren't always tastes or smells, and what sound there was was generally just background noise unless someone did something about that. Sight was largely used for navigating three-space-one-time.
Victor went to the kitchen area of his apartment in meatspace - much preferring his mist-ical personal locality. There, he remembered that he could use the "window" - an odd term for something that couldn't be moved, reshaped, minimized, or readily removed altogether (though such "windows" were also thoroughly outdated) - for seeing another local region of meatspace. It seemed to have an odd sort of film on it, though. Victor banged his fingers into the "window" - always being so clumsy with his off-hand, whichever one that was - but then straightened it out and wiped.
The film lacked cohesion - only the parts that he'd touched lost their tinge. He also noticed that the film remained on his hands, but then remembered his object-orientation and realized that it would have been inappropriate for it to disappear here. Still, it seemed interesting, so he went ahead and wiped it off into some Kontainment®, making a mental note to have it mass-spec'd later. Victor also noticed that the "window" didn't become clear. He tried to look closer, before remembering that his physical eyes could only zoom in so far. He started to realize just how good it was that he went out every now and then: Imagine what he'd forget if he never came out!
What Victor had seen were some odd streaks along where he had wiped. He couldn't see them anywhere else. Moreover, at either end - where he had started and ended the wipe - the marks resembled the "fingerprints" from the old police procedurals. That triggered a realization: Of course, in meatspace, his fingers had imprinted the "window".
Victor went back to what he'd intended to do in the first place; he looked out the "window", where he'd wiped off the odd film. Across the street and down a bit, he saw some punks. It was obvious that they were punks, since they were outside, but didn't seem to be going to or from anything. They weren't stretching, or rehearsing their movements. They were just relaxing, talking to each other, and overall acting like they were very comfortable in meatspace.
There looked to be five of them, as two men and three women. Both men wore brown hats. They were quite tall for hats, and very cylindrical. They looked like they belonged on Abe Lincoln's head, though they were shorter and browner than that. Both men also wore some odd outfits, with at least two layers on the top halves of their bodies. They didn't match, though. One man had a black thing on top, which looked like it would work quite well alone, and without need for the buttons. Below that, though, was a white shirt with sleeves that went all the way down to the wrists, and some sort of odd layering on and above the chest. Victor would have thought it a waste of cloth if he'd ever heard of "waste". The other man wore a brown thing that looked like a thicker version of the aforementioned white shirt, except that it seemed to have been cut down the middle and have buttons in it, though those weren't being used to hold it closed at the moment. Thanks to that, Victor could see parts of two more brown layers below that, but he wasn't sure what to make of them, especially since both of those seemed to have buttons, too! Victor decided to look at the women.
Doing this caused an odd reaction in Victor's "personal meatspace". He couldn't figure out why, since he could barely make out the women's forms, for their extensive clothing. One wore a blue dress, though it had sleeves attached - again going all the way to the wrist - and the bottom part went all the way down, hovering just above ground level. Victor couldn't quite make out how her legs must be shaped, since the outline of the dress was some odd sort of curve that was fixed in some places, but changed in others. As she moved her body while she talked to the others, he saw an odd swaying in the dress, before something finally came out of the back of his brainpan and smacked him: Her dress - at least that part of it - wasn't meant to go along the shape of her body. After mulling that over, he reasoned that there might also be something holding it outward that much, and that her legs weren't even ridiculously disproportionately huge.
The next woman's dress was similar, though it was green and black, and it tended to drape more, though it still failed to convey the shape of its wearer's legs. The last woman was dressed much more reasonably, wearing a white shirt - though, again, the sleeves went all the way to the wrists, and Victor was starting to wonder what they might be hiding along their forearms - and her brown pants looked too big, and seemed to have straps going over her shoulders. She also wore something about her waist, which seemed to be cluttered with large objects.
Victor continued to look at them, trying to recall what flavor of punk they might be. He had heard of many kinds, including the no-longer-extant "cyberpunks", though "cyberpunk" seemed to have been a term that once meant the same thing as "futurist". After mulling it over for a bit, he realized that they were steampunks. It didn't much matter, since all of the remaining punks were the same: Most of them spent all of their time in meatspace, and all of them spent most of their time there.
Victor noticed something odd about how they looked. That is, they seemed to have stopped mulling about, and were all looking the same way. On its own, Victor's brain figured it out: They were looking at him. Victor stumbled back with a start, nearly falling for lack of practice standing. He went back to grabbing to something to taste while he spent some time in meatspace on the principle of practice. Everything seemed a bit blurred and faded. He thought that perhaps he should lay down, seeming to recall that people who didn't feel well in the old stories did that. He found his bed and gently laid his body upon it. Its softness was surprisingly comfortable.
---
Victor awoke with a start. Mostly, he was startled because he didn't realize that he was asleep. Victor also took note of his "personal meatspace", and decided that now was as good of a time as any to go back in, since the device that would hold his body was where he made depositions, and since cyberspace was where all of the entertainment occurred, anyway.
Victor plugged himself into the port, letting automation handle the rest of the things that would attach to his body. He managed to get everything vital handled, but found the world at odds with himself. He had always been considered quirky - he was an out-goer, after all - but now it was like he was crazy. Nobody in the world understood him, and he didn't understand why. He eventually left.
Not more than ten minutes after going back, Victor "wandered out of the mists" again, though he was the only one who called it that anymore.
[END]

This was another story that came to me rather suddenly. There were a few things that didn't get said here, but I figure that I'll make notes on them later. Alternatively, perhaps I'll revise the story a bit.

Super-superregnum

I want to post this before I forget (and before someone else claims it). I think that we should preemptively add a "top" level to our classification/cladistics/phylogeny. It's tentatively a "super-superregnum" level, which puts lifeforms into entire biologies based on their planets (or other regions) of origin. I think that ours should be called "Terrus" because it sounds like "Terran" but "Terran" is already used descriptively in other ways, and because most of these end in "-us" or "-um".
I also hold that one super-superregnum (such as "Terrus") could in fact cover multiple planet, in cases of panspermia, whereby one planet's (or other region's) biology originates from another's.
