    It may have escaped your attention but people who can't walk are normal humans like anyone else. They also have ambitions that are a little more interesting than walking. Maybe you didn't learn that from Stephen Hawking's comments about the colonization of space last week.

    For that price we could have hotels in space, a base on the moon, another on Mars, mining in the asteroid belt, a probe on its way to Alpha Centauri and a probe drilling down do the oceans of Europa. When people throw away good money like that it makes me so angry, I just want to go out and make billions myself so I can spend it on something people will actually care about in a thousand years time. That's it, I'm going to start applying some of my math skills to speculating on the markets.

    The existence of God can only be proved subjectively
    It's more conventional to write this as "the existence of God cannot be proved". There is no such thing as a 'subjective proof', just as there's no such thing as a one [erspn dialog, a one person society or a one atom liquid. If only one person can 'prove' something it is merely an opinion.

    the algorithm is usually N^2
    As I say, modulo a polynomial. The complexity of quantum systems typically grows exponentially because we're looking at the tensor product of the subsystems.

    I'd love to find out a bit more about the algorithms used here. And I'd be interested to know what kind of validation there is for the methods. I guess I can start here. (My background is more particle physics than many-body systems.)

    What does that mean? Any day of the week? Any day regardless of the weather? Are you saying that if it's a lovely sunny day with nary a cloud in sight I can be struck by lightning? If you are, then you're off your head. I might as well worry about my hot coffee quantum tunneling through the mug and burning me.

    In a classical physical system the time to compute what happens to N particles typically grows as a polynomial in N. The masses and positions of the particles form a 6N dimensional space (3 for velocity, 3 for position) and you're typically trying to trace a path through that 6n-dimensional space.

    In quantum mechanics the state of the system is defined by a wavefunction on a 3N dimensional space. The state of a system is no longer a point, it's a *function* on a 3N dimensional space. That means that at any position in this space the function can take any value. So you need to compute the value of this function at every point in this 3N-dimensional space. Suppose we model this really crudely. Instead of considering a wavefunction that varies continuously through this 3N-dimensional space 'discretize' this space. consider just 10 points along each of the 3N axes rather than the infinite number required by quantum mechanics. We can then model the system by computing values of the wavefunction at 10^3N points. Suppose we're dealing with 1000 atoms. Let's model the atoms really crudely as one nucleus and one electron. That means 2000 particles and a 6000-dimensional space. So we need to compute the wavefunction at 100000000...000 points, where we have '1' followed by 6000 zeroes.

    I know that physicists have a few tricks up their sleeves but it seems pretty obvious to me that these guys are actually cutting a lot of corners, and to accurately model this many atoms on a computer anything like what they have sounds pretty implausible to me.

    There's a quick and easy way to look at this. When you combine two classical systems the work required to simulate the combination is typically the sum of the work required to simulate them separately (modulo a polynomial). When you combine two quantum systems you need to multiply the amount of work. Combining 1000 quantum systems borders on the insane...

    I can't quite tell what point you're trying to make. My claim is that regardless of the facts, people take great pleasure in bitching and moaning about their loss of rights and they don't like the facts to get in the way of that bitching and moaning. Most posts on this subject are simply knee-jerk reactions and I expect to see the same old (mis)quote from Ben Franklin and others wheeled out. Slashdot provides what people need to indulge in their favorite pleasure and the readers lap it up. Whether or not the story is true or false is neither here nor there (but judging by my own experience of journalism, it's propbably a gross misrepresentation).

    You seem to have the wrong end of the stick. News reporting isn't about presenting facts. People get a kick out of hating people. This story gives people the opportunity to bitch about the cops and the government and express their hatred. Just read all the posts to this story that people have made to get an idea of how much pleasure people are getting from this story. So please don't spoil everyone's fun by suggesting that they might not have their facts right.

    Kinda weird how a 19 year old is allowed to have sex with more people than a 25 year old, say.
