    Don't project the problems of desktop software onto this situation. There is a whole field of provable reliability in coding, which the avionics industry is very familiar with.

    Which is all fine and good for fly-by-fire control systems, but that's not what we're talking here. We're talking about complete automatic control, which will need to perceive its environment in order to make decisions. It is (literally) impossible to create software that can perceive the situation correctly in every possible situation, and (practically) impossible to create software that can always make the correct (accident-avoiding) decisions based on this information (and it is literally impossible to prove it correct, since there is no limit to the possible combinations of variables). Add crowded airspace (think rush hour) and the fact that any craft that gets into accident won't slide to a stop, but will instead fall like a rock and smash all vechiles below it - unless they manage to make desperate last-second evasions, which will likely just put them into incoming lines and widen the chaos - and total lack of ability to react to anything unexpected (by the programmer / designer) in a reasonable manner, and you have a mass accident waiting to happen - one which will rain burning metal to the city below and send cars smashing through 20th story windows, I might add.

    The avionics industry has nothing that comes even close to handling this kind of thing.

    Compared to full automatic control of a flying vechile, desktop software is simple and works in a standardized environment.

    In any event, they'd have to do an awfully slipshod job for the casualty rates to come anywhere close to what we see now on the roads. Nearly every major city has at least one fatality during the typical rush-hour.

    Which says absolutely nothing about how dangerous driving is, since you didn't say how many cars are driving and how far during the rush hour.

    In any case, this gets us to a little problem: what happens when there's more moving objects in the nearby airspace than the vechile's computer can track ? And what happens when radar becomes useless due to the white noise generated by other flying cars radars ?

    There is an economy of scale here, that NASA doesn't have.

    Yeah. And it calls for reusing libraries and other components from other programs, leading to the negation of the "voting" system.

    No, since killing more people is even worse.

    Which, of course, is an illogical conclusion, therefore proving, by contradiction, that helping others is pointless.

    The chain of reasoning up to point 3 is logical, just unpleasant since it disturbs consumeristic hedonism. Point 4 is wrong, as I stated above. But even if it was all illogical, it wouldn't prove that "helping others is pointless", because "don't lift a finger to help anyone" and "give every last penny to the poor" aren't the only alternatives. Proof by contradiction only works if there's no third alternative, which there is - give some, but not all, of your money to the poor, or go to sites like Hungersite which are ad-funded and give some of the money to the poor.

    The Wiki article gives the one I found most often - the lowest altitude that one can place an object in a stable orbit (personally I would have gone with one of the 'spheres and a harder altitude - personally I see "space" as a lack of atmosphere not ability to orbit the planet).

    These two are connected: it's the air friction that destabilizes low orbits. Otherwise you'd just need to clear all the mountains under your path.

    Besides, the ability to stay in freefall without falling back to the planet is the practical requirement for a region of space to be useful. Without this qualification, a spacecraft is going to have to use its engines to stay in space, and that is not practical with anything short of nuclear drives, and not very smart even then.

    It has been concluded quite a few decades ago that nuclear weapons are pretty much the only thing that can keep China's potentially huge army (in terms of numbers) in check. China knows that as well. In their place, would you really give up the only thing that restores or overtips the balance? Wouldn't you keep at least one nuclear launch site functional, hidden somewhere, capable of retaliation? One is all it takes.

    Of course. But I wouldn't make this a secret; quite on contrary, I'd publicize the existence (if not location) of this site and made sure that all my enemies knew that if they try to nuke me, they'll get the same in return.

    Nuclear weapons are too destructive to be usefull in an actual war. If your opponent doesn't have them, using them in an attack would mean you'd conquer burned-down ruins, while using them in defense is unlikely to be neccessary since no one's likely to be stupid enough to attack a nuclear power. They're only really useful in pushing non-nuclear powers around with threat of destruction, and keeping yourself from being among the pushed.

    So yeah, if I was China I'd keep nukes ready to launch at any time, but I'd also make sure that everyone knew I had them, since they'd do me no good if no one knew about them.

    But the basis for any just government (and really, the only reason we have them) is to protect the weak from the strong. In the end, if those that cannot defend their rights are given no rights, how are we any better than warlords or dictators?

    Do we have just governments ? It seems to me that every one of them is perfectly happy to do whatever evil it can get away with... And no, such governments aren't any different from any other tyranny.

    In any case, I'm not arguing that the law shouldn't protect children's rights, I'm saying that it doesn't do so.

    An adult being spanked has several options: physically fight back or repond using the law (police, lawyers, etc). For the child, since they are (on average) physically less strong than their parents he would only have the second choice, the legal system. If the spanking was not physically damaging then most governments just chalk it up to diciplining a child. On the other hand, if the spanking does beyond diciplin and is physically hurtful (broken bones, scares, bruises, etc), then the law will step in to protect the child.

    That's exactly my point. Things that would have everyone screaming bloody murder if done to an adult are ignored when done to a child. A child is physically weaker, far less experienced and skilled and less mature - and thus less able to deal with emotional traumas - than an adult and should thus receive more protection by law; however, in reality he gets less. This is justified with parent's right to rise their child as they see fit, essentially treating a child as the property of his parents.

    And yet, if you remove this power from parents, you aren't doing the kid any favors. Then he's at the tender mercies of people who in all likelihood don't know him and don't have time to get to know him, and are likely way overworked; in the worst case scenario, the whole thing is outsourced from government to a private corporation, which will do its job as cheap as possible.

    All of this leads to my conclusion that a child doesn't have any rights, but is at the mercy of whoever happens to be his keeper.

    Basicly, even children have rights that the government protects, but most are only conserned with physical protection. Your example of spanking is not proof against this, as parents have been arrested for such actions.

    Were they arrested for hitting their child, or for using "excessive force" ? But I guess it proves me wrong nonetheless.

Since the teacher is a human, he is more likely to give high grades to ideas he agrees with, because those he doesn't agree with are incorrect as far as he's concerned (alternatively he might want ideas he finds "challenging", that is, does not agree with but does not find too offensive either). Also, it is very likely that he had some idea of what kind of ideas he'd get back when giving the assignment; miss one, and the grade goes down.

    All this means that the students job is to guess what the teacher wants to hear and then tell it to him while pretending to agree. That's good practice for your working life, certainly, but it also makes comparing ideas in papers completely pointless - of course many top-rated paper is going to have similar pattern of ideas, since there's only a few patterns that can become top-rated, for a given combination of assignment and teacher.

Since the longstanding tradition is that the law does not enforce any such rights - for example, it is legal to spank a minor while doing the same to an adult would get you jailed for torture - and since the minors themselves are incapable of defending against such violations, due to their lack of resources, I'd say that the minors have no rights, period.
