The consequences of completely abandoning copyright would be very dire in any society which does not completely subscribe to socialism. Before copyright, the natural difficulty that existed to actually make copies in the first place is what gave creators of works some level of control over their own work. If you believe that taking what little (admittedly artificial) control remains on account of copyright legislation would actually be beneficial to society, think again.
First of all, try the following experiment: Since you evidently have silicone tubes to work with, take an 18" long or so silicone tube, and completely fill it with water completely seal both sides, and making sure that there is no air inside the tube. Once you've done this, you will note that the pressure required to flatten it with liquid inside is *DRASTICALLY* larger than it is when it is just air... or even if the liquid inside has someplace else to go, such as what you get with a hose that is experiencing only modest amounts of pressure from one side, such as what you get with a water hose, and not something that you're liable to experience in a non-industrial setting.
But to actually cut off electricity, assuming a conductive liquid core, you are going to have to squeeze it so tightly that not even a single molecule of thickness exists inside the body of the tube across the gap you are squeezing. This is quite a bit thinner than what you need to stop water pressure for a garden hose, and is a *LOT* harder than you might think... since even solid objects that appear to be touching on a macroscopic scale are not *REALLY* physically in contact with eachother at an atomic scale - rather, the electrostatic repulsion between their atoms' electrons will push to keep the substances separated by an distance which is *EASILY* wide enough for electrons which are being drawn by an opposite charge in a conductive material to pass But of course. in general, the level of force required to even get the material to this stage would probably cut the material.
But assuming that it could survive those forces, then the resistance of the wire would rise so sharply as that tiny a cross section was approached, that the heat would melt the insulation, and with a liquid core, it would render the wire just as useless as if it had been physically cut.
Finally, there's also the fact that at these kinds of scales, there's not a whole lot of difference between conductor and insulator, even the best insulators will not prevent electricity from flowing some small distance, and over the gap that you are trying to squeeze the liqud out of, even if you were to actually separate one side of the tube from the other, keeping the tube itself intact, across the gap itself between the two sides of the tube and where the tube is being squeezed, there would be many millions or even billions of isolated pools of the conductor that, themselves, would be close enough to eachother that electricity could effectively arc between them through the insulative material, while still being far enough apart that nominal amounts of macroscopic pressure, such as what you experience in a water hose, would not actually push through.
In the late 1980's, I had occasion to meet a young woman who apparently had a typing speed of just under 180 words per minute. She had won several regional competitions on account of her skill (I imagine largely attributed to her youth... she was not even 20 years old at the time), but she did not hold the title of international record holder.
(To be frank, I don't even know if she or anybody else even bothered to check if she was a record holder or not. All she had ever told me in that regard is that she had won a few typing competitions, but the subject of actually holding a world record never came up.)
I remember it was so weird watching her type on a computer, it was more like watching a 300 or so bps modem spewing text than it was watching somebody actually type stuff.
Google seems to indicate that the current world record typing speed is 212 wpm.
How is it off topic? It was a suggestion that *IF* they didn't want their priority communications to interfere with normal consumer electronics, then there would probably have to be rigidly enforced regulations in place that would specifically prohibit those frequencies for use in consumers electronics.
The responder commented that laws prohibiting the use of those frequencies wouldn't do any good in battle field situations, which is entirely irrelevant to the point I was actually making.
Without an official statement to the contrary, nor any type of real language which might suggest sarcasm (such as "oh noes", as you put it, above), there's no objective reason to believe that they genuinely were being sarcastic. They as much as admit that they are only putting it on pirate bay themselves because they know it will end up there anyways. I don't have a problem with this, but personally, the only real problem I have with what they are doing is that in the scrolling text near the beginning of the film, they as much as explicitly state that downloading it was piracy. I take some measure of pride in abstaining from participating in the community of illegally distributed content, and the only reason I downloaded it at all was because the impression was given that it was okay. Now it still may be legally okay, but in the end, they are still judging me for I didn't pay for it, which is something I didn't sign up for. I stopped the movie as soon as I saw that bit of text near the beginning and have no intention of buying the dvd because of it.
No, i did not decide to pirate your movie. I downloaded it because you offered it for free download
This.
But being insulted as a pirate when I just took their offer? This will surely not help positively with my decision if I shall give them money.
And this. I shut the movie off as soon as the first scrolling text went by, suggesting that I decided to pirate their film. I took great offense at the notion, personally.
The fact is that if the tube can lengthen means it can also bulge
No... not at all. It *CAN*, but that is not the same thing as meaning that it would. And in fact, for something like wire insulation, it probably *wouldn't*, because taking a vertically running wire, for instance, the ability it to bulge would cause it to bulge out at the bottom end of the wire, leaving relatively little conductive liquid near the top, and creating an inconsistent conductivity across the wire.
A balloon's elasticity is such that it's volume can be increased considerably past a point of normal inflation. As you stretch the balloon, the thickness of the skin changes, and it doesn't necessarily have to get skinnier in another dimension like this wire does. With this wire, as you stretch it, the cross sectional area decreases, so the internal volume stays constant. The volume of liquid that you would be trying to squeeze out of the space where you are pinching would have nowhere to go... and the section itself that you are reducing the cross section of won't expand to accommodate the liquid because you are pinching it and preventing that section from lengthening.
Do they want their new devices to not interfere with normal domestic use of consumer wireless devices?
If so, then I can see that it might be tricky. The only probable solution would be to dedicate specific channels for their use and have rigidly enforced laws in place which forbid usage by consumer devices. If they don't care if it interferes with such devices, then isn't it just a matter of increasing the power output on their transmitter?
But when it elongates, the cross sectional area also reduces... The inside volume remains constant. It doesn't magically create more volume for the liquid core to seep into and liquid dont compress very easily like gasses do. The net result is that there won't be any place for the liquid you are trying to displace by pinching it to go to
When it is free to do so, yes... if you are pinching it, then it *ISN'T* free to elongate along the region that you are pinching it. The result is a shearing force that will almost certainly sever it just as certainly as scissors would.
Where there is no liquid, as in a pinch, there is no electron flow
Half right. Where there is no liquid there is no electron flow. However, your faulty assumption is assuming that there wouldn't be any of the conductor inside a pinched area.
There's a handful of reasons why this is so, not the least of which is the fact that this isn't like a hose where the liquid you displace by pinching can flow out of either end... it's a flexible container, but it's closed on either end... and it's also *FILLED* with liquid that doesn't compress, and not merely partially filled, leaving much compressible gas inside, so pinching it doesn't leave the liquid with anywhere to really flow to. The container is flexible, but all it can do is stretch to accommodate the change in the cross sectional area of the wire. The amount that the wire would have to stretch to be pinched to such thinness to make room for all of the displaced liquid would, again, tear apart the wire itself unless it were made out of an abnormally ductile substance (which rubber is not). In the end, any amount of nominal pressure pinching would not accomplish this. No matter what mechanism you used to pinch it, the effect would be exactly the same as if you took scissors to the wire, which also accomplishes its effect by simply pinching.
I can't really assert that you couldn't possibly pinch it this tightly at all, only that if you were to, the result would also be a severed wire, and that such high amounts of stress are not liable to happen in practice.
Bearing in mind also that nowhere in this article does it even imply that this kind of wire would be applicable to industrial situations where such forces would have a moderate chance of occurring. The power levels implied by the article are on the order of what you'd get in a set of headphone wires, and not what you'd be using to run power to appliances.
"Because you have higher pressure when hitting with a fist, you are more likely to cause injury to tissue, bones, teeth, eyes and the jaw,"
This line is the only thing that I can find in the article that even slightly resembles evidence suggesting that the hand actually evolved for that purpose, but it seems to make the flawed assumption that since a part of our body is better at doing X one particular way than another, perhaps more natural or obvious way, then the act of doing X must have been the most dominating factor in determining the way that body part evolved, ignoring the significance, or lack thereof, of the benefit it might offer compared to the benefits offered because of other attributes. I would personally suggest that while it may be true that part of the hand's evolution could be attributed to hitting (I believe it was more for self-defense than it was actually being violent), the evolutionary advantage of the human hand for grasping and utilizing objects to do what we will with them almost certainly far outweighs that.
...it just has to be small enough to separate the liquid conductor
Which I am asserting that no normal amount of pressure could hope to achieve without actually breaking the wire in the first place.
Yes, I looked at the picture of the hose... but we're not talking about stopping liquid flow, we're talking about stopping electron flow.
I bet I could crush the tubing with my fingers enough to separate the conducting fluid.
Enough to stop the liquid from flowing through the gap, yes... not enough to stop it from conducting electricity.... at least not without creating sufficient pinching force that you actually cut the wire.
I mean, clearly, if a convicted sex offender is not going ever going to be allowed to reintegrate into normal society and be permitted to relate to society in a normal way after their incarceration, then what on earth is the point of releasing them back into normal society in the first place?
First of all, I don't think you appreciate how tiny that gap would have to be.
Second of all, to even started to approach that requisite size would require *FAR* more work than pinching it with your fingers, or even folding it in half like a tube. You'd need many times more force, and more than likely that amount of pinching force would end up cutting the wire completely long before it would simply halt the electron flow with the insulation intact (unless the insulation itself were as ductile as, say.... gold, which can be pressed to thicknesses on the order of only a handful of atoms across). And the scale of how tiny a gap we're talking about here is small enough that the electrostatic repulsion between electrons is going to be a dominant force, and is going to actively push things away, keeping an almost infinitesimally small gap open, and I'd dare say would require many tons per square inch of pressure to achieve.
Long before you get to this point, the reduced cross section of wire would increase the resistance in the wire enough to cause any ordinary insulation around the wire to start to melt. If the issue of preventing leakage of the fluid can be addressed (which, admittedly, it has not been so far), then that level of abuse (because in practice, it would probably take deliberate abuse to create the scenario where that much force is acting on it, and not something that happens coincidentally) would be about as serious as if the wire had simply been cut. And in general, that kind of pinching force acting on the wire would tend to break it anyways, unless it is made out of some extraordinary material.
No, it would not stop electron flow. It would reduce the cross sectional area, and could thus marginally increase the resistance in the wire, but it would not stop electrons like it would a flow of liquid. Electrons are *REALLY* tiny... far tinier than what it would take to simply make a seal tight against even single molecules of liquid.
It's unlikely you could pinch it thin enough to do what you're describing. This is electron flow, not simple liquid pressure that you can cut off by pinching a hose.
Most of those would actually be completely unenforceable with today's technology... and among those that might even be theoretically enforceable, even at a minimum would require cutting the nation off from all communication with outside countries, including all forms of international travel, unless you could get the entire world to agree to a single governing body.
