  2. Re:Also used to catch legitamite gamblers on The Tech Used to Catch Vegas Cheats · · Score: 1

    Casions make money by selling the illusion of easy money. Casinos are not institutions created to give money to people who are good at math and memorization. Those people are not "legitamite gamblers", because they aren't gambling: they know they will win. They're not even customers, because the house is losing money to them.

    The Casino owners don't gamble either. They do whatever it takes to make sure they win on average. Making sure there's no way the customers can guarentee themselves a win is part of that process.

    The only reason the Casino can get away with its own form of cheating is that they're the ones providing the service: the illusion. They build a fancy world, staff it with beautiful people, and customers gladly hand over their money. Some of the customers gain enjoyment from this arrangement by dilluding themselves into thinking they've "figured it out" or whatever. But any customers who actually do find a way to reliably win _are cheating_.

    The only way to reliably win without cheating is to setup your own casino.

  3. Re:Ok guys... educumacate me on One Hundred Years of E=MC2 · · Score: 1

    If you're really curious and you want a deep, but approachable explination of all things physics, go to your library and look for the Feynman Lectures on Physics.

    So, what does the formula mean?

    The E=mc^2 formula accurately predicts how much energy it will be absorbed or released in a nuclear reaction. This is because the mass of an atom is not just the sum of its protons, neutrons and electrons. It takes energy to hold that atom together, and that energy manifests as mass. If a physicist looks up the mass of Deuterium (Hydrogen with an extra neutron) and Helium (two protons and two neutrons), and then compares 2*Mass(D) to Mass(He), she will find that the He atom is slightly less massive. If you mutiply that spare mass by 300000km/s^2, you get a number (in Joules, I think) which corresponds to the energy released by the fusion of two Deuterium atoms into one Helium atom. That's an H bomb.

    Another thing this formula predicts is that a particle with a non-zero mass cannot exceed the speed of light. As the particle is accelerated its mass (from the point of view of the rest of the universe) will increase. As its mass increases, the energy it takes to accelerate the particle increases. A physicist can keep adding energy 'till the cows come home, and that particle will just keep getting heavier. Remember that Force is Mass times Acceleration. That is F=ma. As the 'm' increases (because E increased), the force required for the same acceleration also increases. In fact, the reason for the c^2 is because of this particular effect. The speed of light is defined by this formula. All zero-mass particles (such as the photon which carries light) must travel at exactly 'c', or they would break the rules. In a way, 'c' is as close as we have to our old concept of instantaneous or infinite speed. From the light's point of view, it travels everywhere immediately. It's only because of relativity and remote observation that light can be said to have a non-infinite speed. But again I over-simplify.

    With all this discussion, you may wonder where Relativity breaks down? So far it's had a hard time with very small scales, so we have Quantum Mechanics for that. There is a distance/time (same thing, really) around the order of the 'plank length', where things start acting more like a finite computer simulation. There are various String Theories which attempt to reconcile Quantum Mechanics and Relativity. It's an exciting time in Physics.

    As always, WikiPedia is a good place to familiarize oneself and find more resources.

    Nah, what the grandparent post is saying is more like "I'm good, but everyone else is bad. Mommy, if you see my brother in the creek you should spank him."

    The theory is that these laws protect people from each other. By giving people guidelines for safe interaction, the "good" people will be within safe tolerances, and the "bad" people will reveal themselves as a threat and can be dealt with.

    The fallacies are the ideas that speeding is ALWAYS reckless or dangerous, and that the local speed limit authority would never use a unnecessarily low speed limit as a source of revenue. The first is an assumption that "_those_ people who speed have no respect for the rules of society," and the second is an assumption that "the police are only interested in our well-being."

    So, the answer to your first question is that FOSS _is_ capable of 'shipping' fully polished 'products'. (Why do people keep thinking FOSS is competing or selling something?) The answer to your second question (what does FOSS need to make something polished) is "people willing to put in the work." The answer to your third question (how does Firefox 'beat the curse') is "people care enough to put in the work on that project".

Students should also find out the biases of the sources they use (there are always biases) and take those into account when trying to form a complete picture of whatever they're researching.

    All media are created by humans and therefore suspect. Wikipedia is no different from any other source in this sense. Wikipedia's adaptability makes it an excellent colaboration tool, but I wouldn't expect it to be either more or less accurate than any other source. The things which make it more accurate are the same things which make it less so. It balances out.

    Furthermore, "Bush is am imbecile" is no less valuable a statement than something more constructive like, "Bush lacks the wisdom and intellect I look for in a leader." The latter is more construtive, but the former must be allowed too, because there's no objective way to tell them apart.
