  1. Re:Young-Universe theory in a nutshell: on Debate Over Evolution Will Soon Be History, Says Leakey · · Score: 1

    Except that we have lots of evidence that the laws of physics did not change significantly in the 5-10000 year frame.

  2. Re:Occam's razor? Please. on Debate Over Evolution Will Soon Be History, Says Leakey · · Score: 1

    A typical example is the approach to the issue of why the bible describes a circular object that is 30 units around and 10 units across

    That's of course no problem assuming that you are not using planar, but spherical geometry. On spheres, the quotient of circumference and diameter is always smaller than pi. As an extreme case, if the circle is the equator, then the circumference is just twice the diameter.

    Of course if you use that assumption to calculate the size of that sphere, you'll find a sphere circumference of exactly 60 units. I somehow doubt they used such a large unit that the circumference of the earth has only 60 of them.

    Yeah, since when weren't there already precise analytical solutions to this? Gravity is a constant vector force downward, air resistance is proportional to the square of the velocity and opposite to that direction, plug it all into f=ma and you get

    mg{0,0,-1} + -k((d/dt)x)^2 = m(d^2/dt^2)x

    where x is position vector. Express x as a function of t, set initial conditions from starting velocity, integrate and yer done. Have I forgotten something? (It has been a while...)

    You've forgotten to actually give the analytical solution to this differential equation.

    "If they cut out the crap for the smart kids, I could easily see calculus by 12 for competent kids. But 6? It seems difficult."

    Last time I checked, the AP Calculus course was taken only by about 10% of high school students in the US.

    So I would say that Calculus by 12 is something for geniuses, not simply "smart kids".

    So if you learn something the majority of people doesn't bother to learn, you're automatically a genius?

    Serving different content based on IP or self-identification is possible even without JavaScript. However if the detection makes use of peculiar behavior of the JavaScript implementation (and the JavaScript implementation will have to have some differences, or else it won't find content which is initially hidden, but unhidden by an user interaction), just fetching from a different UI or with a different browser/spider identification doesn't work.

    And BTW, the spider will certainly expose itself from the very fact that it accesses robots.txt

    If (potential results) > (harm) then DO

    I, your sentient AI robot, have determined that the potential results of killing you in a human way now is that a possibly cruel death awaiting you at some later time has been eradicated. The harm that you'll be dead afterward is not that large because all evidence says you'd die in a few decades anyway, and then you'll be dead forever. Therefore the relative extension of your death time is infinitesimal and thus negligible. I've also considered the removal of possible good feelings in the future, however there's also the possibility of bad feelings in the future which is also removed, and I cannot find any indication which lets me conclude that your positive moments will outweight the negative moments. Moreover I notice that you're optimistic, which means you expect the best, and therefore all good things will be just expected, while all bad things will be a bad surprise to you, therefore I conclude that bad moments would carry relatively more weight to you. In short, I determined it is best for you if I kill you now. Therefore I've put some poison into the food I've just made for you, and which you just have eaten. Be assured that I chose a poison which makes you die peacefully and without pain. After all, as you know, preventing harm from you is my top priority.
