  1. Re:Global Warming on 2008 Is the Coldest Year of the 21st Century · · Score: 1

    It has seemed very strange to me seeing all the hype about global warming and such since I was young, yet seeing years like these recent ones where we are hitting some pretty long cold stretches, this year particularly. Are we or are we not actually having "global warming"?

    FYI, from TFA: "Even so, 2008 is set to be about the 10th warmest year since 1850, and Met Office scientists say temperatures will rise again as La Nina conditions ease. "

    Is there a global warming trend, when "record cold" year is actually top10 warmest in over a century? You draw your own conclusions...

    Nah. What would be proof of global warming is that you get both record highest and record lowest nighttime and daytime temperatures for both winter and summer in a few years. The average temperatures might be going up or down at your particular location, but it's pretty certain that the variation will increase everywhere, which results in the record temperatures pretty much everywhere.

    Yes, but these companies can get hold of this information and use it regardless of it being available via the internet. Yes it might be a little harder but nothings stopping them - that's the whole point of the open court rule if I've understood it.

    But that's just the thing, it would stop them.

    Automated, distributed spidering software can be made arbitarily fast, and having enough hard disk space for any amount of text, ready for indexing and data mining and re-mining at your leisure, with arbitarily fast hardware and without big network bottlenecks. But to do this, you first need to be able to download full versions of the papers from the Internet, for free and preferably invisibly too.

    However, if a human is needed in the loop with every paper, then it becomes practically impossible, because it takes time and costs for every bit of information. If you want just something specific, then the time and cost is irrelevant, and the openness of system is maintained. But then it would simply take too much time and cost too much to get it all, preventing abuse.

    Also, like in this suggestion, if it's not possible to automatically identify persons in the papers, nor possible to look for papers based on people's names, then useful data mining becomes very hard, if not impossible. And as a bonus, if you can't get much useful information, there's not as much money in the data mining business, so overall there will be less organizations trying dig out everybodys private information.

    Considering that court rooms are generally open access, I don't see how bottling the information up later on is likely to be a good idea.

    Any /. reader should comprehend the difference between some information being available by traditional means, and that same information being available worldwide via web to every data miner.

    Tell me, you're not even slightly worried about criminal organizations and foreign intelligence agencies (domestic "homeland security" types probably have full access anyway) and even tabloid newspapers doing data mining court records to find "interesting" potential victims, targets and recruits?

    Full online access does create a problem. Many here seem to argue that openness of information is so valuable that abuse, even criminal use should be made easy. I disagree strongly. I feel a person should have full control over what personally identifiable information about him is internationally available in the internet. For example any court text available online should not have any names in it (names replaced by numbers, for example). The full text should only be available in person, or via snail mail for a cost of "shipping and handling".

    It's really about efficiency. When people can predict what others do, everything goes much more efficiently. The cost of the efficiency is that when the prediction fails, it's worse than if there was no prediction, only reaction. However, in almost all cases, benefits of prediction far outweight the cost of occasional mis-prediction. This applies to just about everything. And the goal in engineering and lawmaking should be to make predicting as reliable as possible, rules as easy to follow and as intuitive as possible, to maximize the efficiency gains and minimize mis-predictions.
    .
    Of course roundabouts are one way to achieve this, but roundabouts, especially multi-lane roundabouts rely heavily both on rules and on trusting that others will also follow the rules in a dynamic (cars moving) situation. Traffic light controlled intersections rely on simpler rules and simpler trust in a more static situation (cars stopped behind red lights). Roundabouts make a more complex situation predictable, so they are more efficient than traffic lights, but once the situation gets too complex, once you just can't trust the other drivers to do what you predict, and can't trust them to predict what you'll do, it breaks down and you need either control (traffic lights) or communication (like direction signals, but they're both unreliable and too simple for solving roundabout congestion, and making them more complex would make 'em even more unreliable signs of what the other car is going to do).
    .
    Maybe one day we'll have cars that talk to each other, and for example in intersections the cars decide who goes when, and then just tell the drivers to either go or to stop (or just slow down in advance so there won't be a need to stop completely).

I'd think it's a wet dream of anybody who's ever played with these kind of fusors.

It'll probably be with a very small fusor, probably using exotic metamaterials designed spesifically for this purpose, with suitable electrical and magnetic properties such as room-temperature superconductivity, and eventually even with properties like self-correcting structure to get around radiation damage to the metamaterials.

Another universe could not be reached, even as a thought experiment bypassing all constraints like speed of light, by travelling in our 3 dimensions. Put something out of reach like this, and you have a different universe.

    I think you're wrong here. String "theories" are not scientific theories just because of what you say. Believing them to be true would be faith based in mathematics.

    However, they certainly are science, a scientific work in progress. Just about everything we know about science started as just a crazy idea. Then it might have evolved into a bunch of mathematics, then a testable hypothesis, and then rejected or tweaked or found out to be accurate to the limits of measurement. But all this is part of science, part of scientific work. String theories are currently somewhat stuck in the mathematics phase, but perhaps already LHC will shed some light in the matter.

    Now I'm guessing you think the research should head in an entirely different direction, and that researching string theories is stupid waste of time. That's fair enough, but calling it unscientific is not.

    But determinism absolutely precludes true free will. This is so patently obvious that I'm always shocked to see people like yourself attempting to argue against it.

    There can be physical determinism (ie. if nothing affects some system, then it will behave deterministically), with non-physical free will (a non-physical consiousness, a "soul" if you will) able to do things non-deterministically.

    So in the absence of consiousness, everything would work like a clockwork, except a being with a free will can make choises that change the physical universe, making it develop in a new, deterministic direction. A new choice can again chance the direction etc, but as long as no choices are made by a free will entity, everything behaves deterministically.

    I think this is what people mean when they talk about determinism and free will being compatible. So they're not being inconsistent, nor are they re-defining terms, they're just using them in a context.

    A concrete example. If I drop a coin, and don't excercise my free will to catch it, it's determined to hit the floor. The path and fate of the coin is deterministic, unless a free will interferes.

Wether your choices are a result of determinstic "gears" turning, or if they are influenced by random quantum mechanical events internally (and externally, of course) making the choices non-deterministic, that still leaves no possiblity of choosing. It's like with dice. With determinism (eg. every side has same number), the the die will always give the same number. With quantum mechanics, any number may come up. In either case you can't choose what number comes up.

    To allow free will in the sense of being able to choose (which IMHO is the only meaningful definition of free will), you need to have something "external".
