  1. Re:Fuel leaking SR-71's on F-117A Stealth Fighter Retired · · Score: 1

    >> I'll wait. I already know what the answer will be. You clearly do not. The range for a modern 747 (which is what Flight 800 was) is about 8000 nautical miles. A transatlantic flight is quite a bit less than that (less than half). Why would an airline want to transport a bunch of extra fuel for no reason? Please tell me. I'll wait.

    Eating cow nuts in India would probably cause some problems, because eating cow in general is frowned upon because cows there are considered sacred. I've seen them sold as "Rocky Mountain Oysters" in the states, and they are quite tasty.

    You know, if someone doesn't get this from the beginning, I seriously doubt that they would be able to correctly implement a simulation that is correct. From grading programs, I know that people screw up their algorithms all the time, and yet still turn them in thinking they have done the job correctly.

  4. Re:Which 25 moves? on Rubik's Cube Proof Cut To 25 Moves · · Score: 1

    .. and if such a sequence of moves does exist, I'll bet it takes quite a bit more than 25 moves for the sequence to land on the solution. That does raise a couple interesting questions I have. Is there a sequence that will exhaust all possible states of the cube, and what would the lower bound of the steps in the sequence of this be?

    We must completely misunderstand each other. I was accusing you of conjuring up some crap to explain current observations that to me seems like another go at some intelligent design stuff. That's why I brought up God, because I figured you for a religious idiot, and I was using something called sarcasm in my reply. Sorry if I was premature in thinking that. Let's see here... > ...or is it something less than a lightyear away and correspondingly smaller? With this statement, you're claiming that galaxies are actually really small and less than a light-year away, when we know from using parallax that the closest star outside the solar system is over 4 light years away (yes, that takes into account the uncertainties in the calculation, there are lower bounds in uncertainty too). Please explain why you think this, and further more, explain why I shouldn't have assumed you to be an idiot for thinking that galaxies could actually be less than a light year away. And what statement of mine made you assume I don't understand that there are uncertainties in measurements? Please point it out. I'd really like to know, so that I don't get misunderstood in the future. By the way, the distance to galaxies is not inferred by using parallax, that only works for star systems close to the earth (but more than a light-year!). If you'd like an explanation on how these particular distances are found, please, just ask.

  6. Re:Simple solutions for NASA on Mars Rovers Facing Budget Cuts [Updated] · · Score: 1

    I think that some of this is because, when a bureaucracy desires more money, they threaten to take away programs that mean a lot to people, so that the people will be more likely to support additional funding. A business can't do this and survive, but a government program can.

  7. Re:Dark Matter? on Matter, Anti-Matter, and a New Subatomic Particle? · · Score: 1

    Oh, I get it, the solar system is the actual size of the universe and the earth really is 6000 years old. In essence, God did it.

    >> Even nearby stars are given a range in the presumed distance as we cannot say for certain exactly how far away they are.

    So you're saying that there are uncertainties in scientific measurements? That's pretty deep. There's uncertainty in the distance to church too. Since we'll never have a stick that can reach the next galaxy to make a precise measurement of distance that you seem to think is required for finding distances, then I guess humanity will be stuck listening to this stupid shit until the end.

  8. Re:Dark Matter? on Matter, Anti-Matter, and a New Subatomic Particle? · · Score: 1

    This seems far-fetched to me. We aren't talking about the movement of a space-probe, but the observations regarding the entire universe. I suspect a lacking in our understanding of cosmology long before the hypothesis that super-intelligent beings are traveling by our solar system and causing our observations to change. Might as well say that God is changing our observations just to screw with us. Do these after-effects of aliens traveling really going to effect the way we see every galaxy behaving, along with galaxy clusters and the entire universe, but still not affect the cosmic microwave background? Come on! Is this a joke? If not, then you better be able to tell us how these travels affect our observations in a way that explains everything we see, and can even predict observations not yet made. You are a very long way from grounded scientific hypothesis.

    >> since black holes are made from collapsed stars, they are baryonic.

    Although I think the original point that dark matter cannot be attributed to black holes is valid, can baryonic conservation within a black hole really be assumed? If I put 10^40 baryons in a black hole, should I expect to get 10^40 back out via Hawking radiation? What does this say about the information content of a black hole? (I don't know much about these topics, so I'd really like to know.)

  14. Re:What worked for me is... on Best Way To Teach Oneself Math? · · Score: 1

    MATLAB or Mathematica is a pretty serious financial commitment if the poster doesn't have access to these resources as a student. There are open source options, and I use them, the they are a little more difficult to learn (Octave, Maxima). Especially for high school level math, I would suggest sticking with books and a graphing calculator (Although there are many great computer programs out there that do all of the functions of a graphing calculator, without the cost / learning overhead of the bigger programs).

  15. Biographies of scientists and mathematicians... on Bringing Science and Math Into Writing? · · Score: 2, Interesting

    Reading about the life of a certain scientist or mathematician was important for me. Knowing that those kind of people exist (all I knew was sports prior to my discovering mathematics, astronomy, and physics), and knowing about their work made me want to know more. Make a list of scientists and mathematicians. Assign each student to one, and have them read a biography about that person. Have them choose a writing topic, and then have them give an in-class presentation so that they can share information about the scientists and mathematicians to the rest of the class. You should have no trouble filling out a list. The ones I read about when I was young included Marie Curie, Einstein, Fermi, Newton, Euler, Gauss, and Bohr.

    Another option: donate resources to organizations that seek the protection of civil liberties. They will pursue stuff like this in court. The courts are an important part of this nation's balance of power, even if it isn't very balanced. Also, encourage your friends and family to learn about the importance of civil rights in this country. Teach your kids how to say no to a police officer's request for a search without warrant, even if they have "nothing to hide". Make sure they understand the importance of the Bill of Rights, and how these rights are designed to protect people from their government. There are many websites filled with this kind of information. It's unfortunate that every generation must spend so much of their time defending their rights, but it is a problem that is unlikely to go away completely.

    More control than sitting on an airplane, which was my original point. I also referred to it as a "psychological effect", which doesn't rule out the fact that illusion is responsible for it. Still, I do believe that responsible, defensive, and "friendly" driving can do much to decrease one's chances of getting in an accident, even when others drive like lunatics.

    "It just looks bad on the news," I think there is also a psychological effect of being powerless to control a situation, as in the case of being on an airplane. Driving to work, people can take steps to reduce their chances of being in an accident if they choose. This is not the case in a plane.

    Wonder no more, there is a possible explanation. Adding armour to a shuttle would make it heavier, and heavier things have a hard time flying, especially into space. It's not the foam by itself that is so damaging, it is the foam moving at high velocity that is so damaging. If you have better solutions, (and a demonstation of your solution) I'm sure NASA would like to hear you out. They do, after all, need some fresh new ideas when it comes to human spaceflight.
