    You definitely need a medium, but the nature of the medium is highly questionable. (You need something to keep all distances from being in the same place, and a sea of virtual particles counts as a medium.)

    More precisely to the point, any manifold can be considered a medium to those things that are embedded within it, as it applies constraints to what they can do, defines their neighbors, etc. And moving is done WITHIN the manifold. Please note that this doesn't even need to have a consistent metric to be true, much less any resistance.

    Perhaps you use the word differently, but I'm not aware of any formal definition. (Dictionaries don't count, as they are never precise enough when talking about physical phenomena.)

    That is technical protection, but it doesn't keep someone from getting a patent on it. And the patent will be presumed valid, so you will need to prove in court that your use was prior art. And that's not only expensive, it's dangerous. The court may decline to accept clear, verifiable proof. The patent examiners only look in a few places, and often a trivial change is enough that they won't find the prior art. And this isn't even unreasonable. Consider the number of different terms used to describe running communicating programs simultaneously on multiple CPUs of a multi-cpu computer. Now invent a new term that's also appropriate. See how easy it is. Searching for "woven programming" won't find concurrent programming, or threads, or multi-processing, or... well, any of the other terms used by various groups to describe the same thing.

    I'm sorry, but the USPTO is doing such a bad job that totally eliminating them would be an improvement. I will agree that a patent system is valuable, but it's also incredibly dangerous and prone to "corruption". (Not in the usual sense, but in the sense of knowingly not carrying out their explicit duties.)

    The first step should mean to make patents be required to be sufficiently specific that those skilled in the art (being patented, not of legal interpretation) can reproduce the invention. The second step of the process, if you aren't just going to revoke all exising patents and close the USPTO would need to be to remove the judicial presumption that a patent is valid because it has been issued. I doubt if 50% of the patents should have bee issued. The third step should be to remove the special patent courts, which increase the cost of defense against an invalid patent dramatically, in foster a wierd language such that even normal lawyers aren't allowed to claim to understand what a patent means.

    Passing patents up to a higher board of patent office officials will just enshrine the current mode of operation. If you must do that, pass the patent to a board of specialists chosen by lottery from those qualified in the specialty that the patent claims to cover. (Reasons for rejecting that patent by this board cannot include "that won't work" but may include "that's too unclear to understand". In fact, perhaps that should be their only reason for rejection. Perhaps one should also include a requirement for a working model, but I'm unsure about that. Plans for a working model, anyway.)

    Excuse me, but what made you think this wasn't a part of the massive interaction called "global warming"...(which has very little to do with your current weather).

    Ocean acidification is caused by CO2 being dissolved in the oceans, and the level of solution is in approximate equilibrium with the level of CO2 in the atmosphere (though you need to figure in lots of lag). While the oceans are relatively cool they can absorb extra CO2, as they warm it becomes more "eager" to get out of solution, but with the atmosphere levels of CO2 being high, instead of being expelled into the atmosphere it "tries" to dissolve things. (CO2 dissolved in water is carbonic acid ... H2CO3. A very weak acid.) When the temperature of the ocean is lower, not only is the CO2 more soluble, but the resulting H2CO3 is more stable, and so less acidic.

    What's been happening is that as the amount of CO2 in the atmosphere rose, more was dissolved in the (colder) oceans. As things warmed up the ocean has become more reluctant to hold the CO2 that's already been dissolved. But the oceans have so much more thermal mass than the atmosphere, that they've been warming considerably more slowly. Over the last decade, however, their temperature has been increasing, and they can't emit the dissolved CO2 into the atmosphere faster than it's absorbed, because that level is also increasing, so the oceans have become more acidic.

    So this is an expected part of global warming, and anyone who is surprised by it just hasn't been paying attention.

    Sharks do have some bones, but it's not clear that they can't adapt to reducing the quanity, and with an internal skeleton the difficulty of laying down calcium reinforcements is an economic problem, so while I expect sharks to reduce the amount of calcium reinforcement in their skeleton, I don't expect it to sound their knell. Oysters are a different matter, similarly clams, corals, and plankton with calciferous reinforcements. They will probably be unable to do so.

    Fish are in an in-between spot. An increasingly acidic ocean increases the cost of maintaining a calcium reinforced skeleton. Smaller fish, especially, may find the increased cost too much to sustain. Perhaps they will be able to adapt by switching most of their skeletons to cartiledge. Perhaps they won't. And larger fish are generally dependant on smaller fish for sustainance. Perhaps they can switch to jellyfish, but jellyfish are rather low in calories/cc.

    It's not clear that plankton will suffer unduly with acidification. Some plankton depend on calciferous skeletons, but by no means all. Some even use silicon. Expect "carnivorous" sharks to get smaller, and subsist mainly on jellyfish. Whale sharks may do well...or might not. Baleen whales may do well, as they are slightly insulated against increased oceanic acidity, and live on plankton. Walrus and seals should expect to do poorly, unless they can adapt to living on jellyfish (unlikely?).

    And fishermen should expect to do EXTREMELY poorly. I've eaten one decent sushi made with jellyfish eggs. It was expensive enough that I haven't ordered it again, even thugh it was good. I don't think I've ever eaten jellyfish...or been offered any. (FWIW, Jellyfish are mainly salt water, and that may be why.)

    OTOH, a lot of the current reason for the increase in the number of jellyfish is overfishing. Ocean acidification, while it is happening (and destroying corals, oysters, etc.) may not be what's killing off the fish.

So Chinese has a good chance, but it's sufficiently difficult to learn (especially to read/write) that the most likely language to supplant English is ... English.

Or possibly a horse drawn wagon. (That's really unlikely, as there's no place for the horse.) My parents house once had a two car garage, but when the house was purchased that had already been converted into a room, with the garage door removed and replaced by a wall. They did, however, have a driveway with parking for two cars. That still exists, but now is occupied by an RV, and the cars are parked on the street. I don't know the details, but an increasing number of their neighbors also park their cars on the street.

    Additionally, while it would possibly be safe in the area where my parents live, I live in the city rather than in the suburbs, and leaving something with resale value available to be lifted is a good way to loose it. Businesses have lost benches that were secured with concrete blocks. The city has lost such a large number of garbage cans that they have replaced them with a much more inexpensive model which has essentially no resale value.

    Charging purely electric cars is going to be a problem once they move into more populated areas. Your idea of restaurants being the site of charging is equally out of touch. Most people don't go to restaurants very often. and, for that matter, the newer restaurants in this area don't HAVE parking lots. For that matter, I believe that the same statement applies in downtown San Jose, and even Alameda. Walnut Creek may still have restaurant parking lots, as it's well out in suburbia. That will stop when the population gets denser. Perhaps city owned parking lots will put in chargers for electric cars. Maybe. I'm not saying it's a problem that can't be solved, just that its going to be a real problem that will get a lot worse if it isn't addressed.

Mind you, most systems allow some groups to scam.) Kit Carson, the noted traitor, cannibal, and indian scout is a individualist hero.

    Communalism which is people giving their loyalty to their immediate community, is what many people think of when they praise individualism (but not when they act on it). Again Communalism tends to depend on a strong leader, but often that leader is expected to ensure that everyone accepted as a member of the community is supported. It also tends to maintain itself by "outcasting" persons judged not suitable for membership in the community. In isolated groups this outcasting can be quite violent, and can result in death. This binds the group more tightly together.

    Nationalism is an distant descendant of Communalism, and tends to be formed by communities amalgamating into groups too large for everyone to know everyone else. It's commonly seen around us in a developed form, but the essential ingredient is respect for written laws. I'm not sure what to expect when the central authority of the nation evinces distaste and disrespect for the law, but it can't be good. The most likely result is the reorganization around some different authority. I don't think I've ever seen this happen in a nation before, but it has much similarity to the way the Nazis took over Germany. Everything was done following legal forms, though only the forms. Much the same seems to be happening now in the US. Germany didn't last long enough to determine what it would have evolved into, but I don't think it would have been pleasant. The US seems to be much more likely to survive, as in not be conquered, but only be subverted from within, and it's even possible that the persons doing so believe that they are protecting the country. Barely possible, but possible.
