    Surely one has high entropy and the other has low entropy - yet they're identical!

    The entropy is the same. It doesn't matter how they got in that state. Deliberately placing stones (or molecules) in a disorded state is still a disordered, and thus high entropy, state.

    One useful way to think of the entropy of a system is in terms of information. The amount of information needed to describe a system represents its entropy (in a real and quantifiable way according to QM and Information Theory). A smooth rock wall requires less information to describe than randomly scattered rocks. A crystalline solid requires less information to describe than a plasma. A .png of random noise requires a lot more information to describe than a .png of a solid color -- as can be seen by how well the two compress.

    It doesn't matter how you create the .png of random noise, the result will still compress badly due to its high entropy. Though in practice humans are bad at generating random numbers so the hand-placed "random" .png will have less entropy than one created from a truly random process. If we assume the result is the same, though, then so will be the entropy.

    You're drawing a line where none exists, and in the wrong place to boot.

    Engineers develop useful, practical things. Things that serve a particular need, that can be made economically, etc.

    Scientists develop things, too, but they aren't as often concerned with the direct utility or practicality of what they develop. For instance what these scientists developed is an ingenious proof-of-concept that could eventually be developed into a practical procedure for replicating materials, possibly by a chemical engineer.

    However scientists also frequently develop practical, useful things. The PCR process you have seen mentioned in this thread is incredibly useful and practical, and was developed by a chemist.

    Sometimes the line gets really blurry, like in the development of a new technology for silicon IC fabrication. The material science and the material engineering are closely coupled and it's hard to say specifically which is which in a given case, outside of edge cases.

    And as I said, I agree completely on the purpose and validation of these systems. Now, how about taking a look at some statistical analysis both before and after the top500.org website was established, and validate that overall spending on these massive supercomputers, as well as average upgrade timelines, is NOT somehow tied to the "king of the hill" theory.

    So what if it the keeping of a Top 500 list of supercomputers spurs governments and other organizations to compete to produce the most powerful computers? The problems these supercomputers are solving are problems where you can always throw more computational power at them to get better answers. You agree that this purpose is worth while.

    I go back to what I said before. This is a tiny portion of the budget, a tiny portion of our debt problem. It's something that pays dividends. It's part of our spending that makes no sense to cut. Not because we're competing over who can produce the most data-crunching, the most science, the most dividends. This is a good thing.

    Fair enough. That's true, but they modified it a lot, creating a structure that as far as we know doesn't exist in nature. It replicates without any of the normal cellular chemistry that makes it happen naturally including enzymes, which separates this from the Polymerase Chain Reaction technique for DNA amplification someone mentioned below. It also allows them to replicate structures other than proteins composed of amino acids defined by the normal base pairs.

    They even fabricated the DNA they used, so it's technically artificial. In a more meaningful sense, maybe it's not completely artificial. Not to the extent of things we might make in the future. Still, I don't think it's complete hyperbole for a headline about a significant step.

    And it could be the case that the birds they used didn't evolve from t-rex, but rather some other (possibly completely unrelated) species of bird, which would skew the results.

    The common ancestor of birds is not T-Rex, so yeah. The most likely ancestor is one of the raptor family of dinosaurs -- aside from having a generally a more bird-like skeleton, a main key is in the structure of their wrists which can be seen evolving increasing degrees of flexibility in the raptor line to be more and more like the structure of a modern bird's wrists.

    That said, a modern bird is still going to be the closest living relative to T-Rex. They're probably closer to T-Rex than crocodiles are.

    Its such an easy-to-adapt to difference from earlier WIMP-style interfaces that I can't understand why so many people on Slashdot are enraged by it. Every non-technical user I've found who has used a similar interface (either the actual Ubuntu one or the Win7 one looks and behaves similarly) prefers it to its predecessors.

    I sure hope that experience carries over to me and my non-technical friend.

    I personally was able to "adapt" to Unity quite quickly, but after giving it two months of daily use to really give it a chance, I decided I just didn't like it. There are unnecessary steps between me and launching an application that isn't one of my most-frequently used, launcher buttons don't work how I want, and the menu placement is a disaster when used with mouse focus (which is essential to the way I use multiple windows). Back to Ubuntu Classic for me. If Unity is my only choice, then fine.

    My friend, who lacks the years of experience using various GUIS that I have that lets me adapt to anything easily, I'm worried about. I can already guess a lot of the things that will annoy him. Like the task bar hiding behavior, the way taskbar buttons behave differently the first and second time you push them, the little 'see additional' tab in the applications menu he'll have to hit to see the app he's looking for. Oh and good lord the scroll bars that pop in and out of existence based on your mouse not actually being over where they are supposed to be.

    In the end it'll be a good experience for him to have to adapt, but in the short term it'll just be intensely frustrating. And in the long term I'm still not convinced it's the best interface for him (or anyone) to be using.

    Maybe I'm wrong and he'll take to it immediately. I really hope so. I still won't like it, and that's not because I'm against change.

    Right. There is currently no legal decision about non-state actors taking things from space, but the sanest legal theory appears to be the 'international water' rules, which essentially say that 'As long as someone does not appear to be control of it, it is fair game.'

    That's really a gross simplification, especially when talking about government property. The government retains their claims on many things which they are definitively not in control of because it's a sunken wreck on the bottom of the ocean. Unless the U.S. government specifically released their claim to the moon rovers and their contents (which they didn't), or this astronaut's claim that he was given the camera as a gift is true, then it's a pretty clear-cut case that the camera is government property that he misappropriated.

    The jurisdiction-on-the-moon issue is a red herring in this case. It would only be relevant if the astronaut was living on the moon and the U.S. wanted to sue him according to U.S. laws. Then jurisdiction would determine if they were able to do so. Taking government property outside of government jurisdiction does not render it not-government-property, nor does stealing government property while it is outside government jurisdiction render it not-theft. Not under the law of the government in question.

    So for the limits of U.S. jurisdiction to help him now, he'd have to move someplace where the U.S. does not have jurisdiction so they couldn't sue him for breaking the U.S.' laws. Also it'd have to be a place that did not recognize the U.S. government's ownership of the rover parts, so that it would not be a crime under their laws, either.

    But as long as he's in the U.S., then he's under U.S. jurisdiction, and what he allegedly did was illegal according to U.S. law.

    Hundreds of millions is nothing compared to the debt problem at issue, super-computer purchasing is not a significant contributor to that issue, however scientific advances that can only be achieved via such computers can provide returns far above what was spent and do orders of magnitude more to resolve our debt issues than it is contributing to them.

    There's nothing un-libertarian about a contract requiring someone purchasing a home in a development to have to abide by certain rules, including clauses requiring exclusive use of a particular police service (or jus primae noctis for that matter). If the home buyer doesn't like the terms of the contract, they can simply purchase a home somewhere else! To disallow this kind of contract would be to restrict the land developer's right to dispense with their property in any way they see fit.

    In Rabid Libertarianism, the only law is property and contract law, and there are no restrictions on contract law because that's unnatural regulation. The escape from situations like the above is always simply "You can choose to live somewhere else" or "You can work somewhere else".
