    rotational motion != rotational acceleration.

    Egh. I meant "rotational motion != angular acceleration", since Torque = (a constant)*angular acceleration.

    That's what happens when I read a confused post---I get confused with my own terminology, too!

    No. Rotational acceleration is different to linear (in fact quasi-linear for gravity).

    So, I guess you are drawing the distinction between \vec{a} // \vec{v} and \vec{a} \perpto \vec{v}?

    Fundamentally, how does that make one type different from the other? (In fact, gravity can be categorized to neither. In the case when you have no angular momentum, gravity will be acting entirely as "linear acceleration" if you choose to draw distinction, while if you are in a stable orbit, gravity is providing the "rotational acceleration" you need to stay in orbit.)

    Either way, a simple accelerometer (er, a weight hanging from a string) will measure them just fine (the only difference might be, from an inertial reference frame, rotational acceleration is constantly changing (in direction) whereas linear acceleration can be constant), and there doesn't seem to be any difference (other than the qualitative difference, as in difference between sweet taste and bitter taste---and since different parts of the tongue is sensitive to different kinds of taste, why not categorize those as separate senses, too, then?)

    No! One is torque, the other is force. Different things. Different units too: force=N, torque=Nm.

    rotational motion != rotational acceleration.

    However, the fact that something is rotating does mean that there is force (and thus acceleration) on the object. Force-torque distinction is quite irrelevant here, I think.

    PS. Oh, and the fact that units are different is even more irrelevant---consider this: Torque = N*m and Energy = m*N ==> Torque == energy? This is absurd. On the other hand, Temperature = Kelvin, Energy = Joules ==> (Internal) energy has nothing to do with temperature? Now that's even more absurd. Most conventional units are quite arbitrary and not worth being cited for justification (by itself).

    The lack of a late fee does not imply the lack of a due date. The due date is still there, and you are still obligated to return it by then.

    That reminds me of my school library check-out policy. At UCB, there's no late fee for any checked out materials---but, if you keep it out for too long without renewing it, eventually you do have to pay for the book, or reshelving fee, if you return it (I haven't had to pay that yet, but I heard it was pretty high...).

    Now, AFAICS the difference is, when I keep the book for too long, I get an e-mail notice about the item after a grace period (about a week past due date), and after that I, again, have a grace period for either returning the book or renewing it---it is impossible for me to just forget that I checked out a book and go on for a month (past due date). Blockbuster should have done the same thing (if they were operating with good faith) since now they allow a week extra past due date---what prevents them from sending out a notice about the overdue material and informing the customer about what will happen if they don't return it quickly?

    Actually, this theory has already been proven.

    IMNSHO, but that was the worst proof of infinite number of primes. Why introduce unique factorizability when you don't need to? Why introduce something foreign that you are not going to prove when there is absolutely no need for it?

    The most elegant proof I've seen so far (but I don't know any website showing it, so I can't link to it) is this: For any given N, an integer, consider N!+1, which is greater than N (where N! is defined by N! = 1 * 2 * 3 * ... * N). If this number is divisible by no other number than 1 and N!+1, then we are done (i.e. we have proven that given any arbitrary integer, there is a prime greater than tat integer). If this number is divisible by a prime, than that prime can't be less than or equal to N, since any integer (not equal to 1) less than or equal to N divides N! (see the definition of N!) but does not divide 1. Therefore, the prime that divides N! is greater than N. QED.

    This proof involves no assumption (additional to assumptions (i.e. axioms) of the set of integers) other than this (which also happens to be much easier to prove than factorizability into primes): if n divides a + b and n divides a, then n divides b as well.

    Very valid point---and I think we agree on software patents, at least. (And, yeah, I was half-joking about WWII reference... and it probably wasn't in such a good taste, either :(...). I just wanted to add one thing:

    Yes, but the idea on its own is no good without the time and materials to create the equipment. A description of a new experimental technique is not really analogous to a completed application, it's closer to a description of a new algotrithm.

    To stay on topic (i.e. software patents, which RMS is speaking against in TFA), that is exactly what is wrong with software patent---it patents ideas not implementations (IANAL, but that's what I've been hearing). So, the patent protects what is no good by itself (and, yes, the whole getting-the-inventors-to-reveal-their-secret argument and promoting-innovation argument don't work for this reason) and, yet, it takes away from developers the very first thing they need in developing a software.

    Big shocker that this garbage is coming out of Berkeley. First of all, you equate the value of software to the cost of duplicating it. Pretty convenient that you can ignore the cost of creating it in the first place. And as for software being a public or private good, that's why we have licenses. If you create the software, you get to decide which license to use. What an amazing system!

    So, what "fundamental economics principles" are you citing? Your developmental cost ("opportunity cost", cost of living, etc.) is part of "sunk cost." (And I believe one of the fundamental econmic principle was this: "Sunk costs are sunk", and another one "Sunk costs are really sunk".) I was referring to "marginal cost", which has to do producing an additional unit---i.e. copies---and it may be considered a "fundamental principle" (I'm not sure if it is, IANAE), but it is clear that "price of a good should exceed its marginal cost." Softwares (and intellectual property in general) are unique in that the marginal cost is phenomenally low---whether that justifies a phenomenally low price is arguable, but it is arguably the strongest blow against $200 softwares (which is one of the consequences of proprietary softwares).

    Now, with this understanding, does my point about RMS (and probably OSS) not breaking any "fundamental economic principles" get across to you? Don't let my domain (*.berkeley.edu) cloud your eyes---otherwise, my predecessors would have fought for free speech in vain.

    PS. BTW, you are forgetting that the corporations' support of software patents (which RMS is opposing) are nullifying the very force of licenses that you are so fond of. Would you like an "artistic patent" so that no artist/writer may "steal" an idea from another?

    The ironic thing is that if all software were free, there would be no software market and therefore no monopoly, so I don't understand why OSS advocates piss and moan about monopolies when the system they are advocating has no economic market.

    There is no market for "new, exciting physical theory." Nor was there a market for "a new way to split an atom." Yet, somehow, these physicists manage to make a living.

    Why? Because, while there is no market for the products of their labor (as was precisely your point, OSS will eliminate the market for software), there is a big enough market for their skill and talent to draw the brightest of the generation to the field. What is preventing computer science from becoming the same? What prevents a software developer from getting paid to develop an application, as opposed to collecting royalties? (Now, now... I'm not criticizing book-writing (since writers _do_ collect royalties), as there is no way to make a book "closed-format".)

    Propriety softwares are not much better than software pattents, as far as innovations and new developments go. Consider how long the "trade secrets" of artisans of old hindered progress and forced so many to reinvent the wheel (not to mention the loss of techniques that some countries (*coughkoreacough*) consider to be their national treasure).

    PS. Now, of course, the fact that physicists (or any academician) can earn enough to support themselves have little to do with economics or capitalism---hence the criticism that academics live in ivory tower. But, that goes back to my original complaint: every time you criticize an academician for not caring about "fundamental economic principles" (*coughcapitalistpigscough*) you criticize all academics for living in ivory tower---by all means, you have every right to do that, but why would you want to deny that you are actualy doing what you are doing (of course, unless Bill of M$ became too big of a role model for you).
