    Well, there are basically two camps in the Christian world, and a third, loosely wedged inbetween.

    There are the "bible believers", who insist that the Bible is 100% accurate and true - word for word, the Perfect result of God's Will. In that case one cannot believe otherwise, that the Earth is around 6000 years old, and you need to fabricate some kind of delusional architecture to rationalize this and scientific evidence. There's the passage that states that Pi is 3. That's enough for me. I can prove that's wrong on a sheet of paper right in front of me. One can also look at the various widely divergent groups that have splintered off from Catholicism; all claiming to be "bible-believing"; all disagreeing on many major points.

    Then there are the "fallibists", who believe that the Bible is flawed, either by error or translation and reproduction, or purposefully, for nefarious purposes.
    fallibists have to believe that some part of the Bible is true, but who is to decide what parts? The reader? The Holy Spirit? it's a big mess.

    Wedged inbetween are the ones who try to rationalize it by saying that parts of scripture should not be interpreted literally, and that the story of creation talks about days, but days to God are really millions of years. There is even a little bit of Biblical scholarship I believe, that backs this up (language of the period was a bit sketchy when it came to talking about numbers, especially magnitudes). But at some point, these folks have to admit that they are fallibists, because you must accept that the words, as written, do not adequately communicate the message, because everyone who reads it, gets a different meaning. That runs counter to the whole purpose of language, and you'd think that a Perfect Being with Omnipotent Will would be able to ensure that things went smoothly in the translation and dissemination, in order to prevent a corruption of His message.

    So, if we accept that the Bible is flawed (whether one believes or not), we can throw out this childish concept that Darwinism and Science are evil lies spread by Satan.
    The theological problem this creates though, is that Christians have no solid basis for rituals, or laws. And therefore, all religious authority is basically folly.
    I've read the Bible, and some of the quotes from that Jesus guy seem to agree on THAT point.

    Whichever school of thought on Biblical authenticity is correct, you still cannot escape the fact that even "strict" interpretations vary and differ widely. So accepting fallibism doesn't really threaten anything. When the Bible becomes more important than the God, you should re-think your relationship with said God.

    OK, assuming you're not trolling: the "functionless stubs" are ARMS. Take a good look at the next chicken you eat - notice the shoulder blades and fingers, things that probably wouldn't be there if the wings evolved late in the game from nonfunctional lumps of muscle on the animal's back.

    This will probably sound ridiculous, but consider for a moment that feathers are useful even if the animal can't fly. (Flightless birds still find them useful.) Now consider for a moment the small theropod dinosaurs one found running around in the early Jurassic - Coelophysis, Compsognatus, and kin. Two-legged stance, long tails, fast runners. Predatory creatures with long fingers for clutching prey. Hollow bones for reduced weight = more efficient use of energy when chasing prey at high speed.

    Now let's assume that a feather is basically a modified scale. A mutation causes one of these creatures to have "skeletal" scales - ones that are not solid like lizard scales, but are split into the fibers that make up the scale. Tada - a fluffy scale. This animal is able to survive the winter more easily because its fluffy scales allow it to conserve body heat - and it passes these genes on to the next generation. A few more mutations down the road give the fluffy scales the interlocking barbs and stiffening central quill, and we have feathers.

    Useful even though the animal doesn't fly.

    Now remember what our creature looks like. It stands on two legs, head upright, with hands outstretched in a "gonna grab you" position. Cover it with feathers instead of scales and let it proceed to run - long feathers on the arms become an advantage because the creature can use them in hunting! One outward "swoosh" of its arms and a small prey item would be literally sucked in. Or it could use the arm feathers to make it easier to turn at high speeds.

    It would have been a sheer happy accident that the creature one day went up a tree chasing food, fell off a branch, and discovered it could glide to the ground. A few generations of this breeds creatures with much stronger arm muscles - and powered flight is born.

    It's also not the only way to determine age. There are other radiologic dating methods used for different ages - using different elements - and if a sample falls in the overlap between two techniques, it provides an excellent cross-reference. You can count annual phenomena - sediment layers, tree rings (and compare seasonal difference between trees that died at various times and build a complete timeline of trees), etc. You can even use fossils - strange as that seems - since some fossils are known to appear only in a certain strata, if you find those fossils in a layer you can say with reasonable certainty that the layer is of similar age to layers containing that same fossil elsewhere in the world. And elsewhere in the world that layer may sit in the middle of a 300-ft-high column of unbroken strata - the top of which can be radio-dated to 175 million years, the bottom of which can be radio-dated to 330 million years, which leaves you a pretty good way to visually estimate the age of your layer. Corroborate it with enough other layers worldwide, and enough other dating techniques, and you can pin down the age of that layer and any fossils you find in it rather neatly.

    Christianity is based on a BOOK, written by humans claiming to have gotten it from God. That book conflicts with observable reality in many places - go catch a grasshopper and counts its legs and you've just proven the Bible wrong. Accompany astronauts into space and notice there is no firmament from which stars hang and you've just proven it wrong again.

    Yes! To Obi-Wan you listen!

    Not sure who said it, but there's a great line I read: "it's not survival of the fittest, it's survival of the fit." If you have a mutation that lets you find a place to live, eat, and breed, you'll pass on that mutation. If you end up competing against the nonmutated versions of yourself, either they'll die off, or you'll die off, or they'll move away, or you'll move away, or you'll specialize on different kinds of food and it won't matter. That's why humans and monkeys both still exist - we came out of the trees because the monkeys were eating all our damn bananas, so we decided to go look for food elsewhere.

    It's always amusing when creationists point out when one or another human ancestor is still around (like the coelacanth) and that this somehow disproves evolution. Well, I suppose it does, if disproof of evolution is the assumption to begin with, ANYTHING will support it. All it really demonstrates is that there's no reason the ancestor needs to go away - if it finds a niche where it doesn't compete with its descendants, great! The coelacanth basically found a spot to hide in Madagascar and another in Indonesia, where it managed to maintain a small breeding population for a few million years. Nothing about this disproves ANY of the mechanics of evolution - in fact it supports it, because it demonstrates the importance of adaptation to one's environment. The coelacanth has the potential to go on land, but neither does it use this potential, nor has it lost it (well, not much of it anyway). It works just fine as a fish.

If closer examination indicates that it IS what you say, a modern human three million years too early, yer durn tootin they'll follow it up - to be able to rewrite the family tree, of course with actual evidence to back it up, is probably the secret dream of every paleontologist.

Never would you expect to find the weird shape that appears onscreen - and you certainly wouldn't expect to find miniatures of that shape (each with unique patterns of streamers trailing off them) hidden all around it with smaller versions of the shape around them.

    We can explain where living things came from. But so far as I know, no one has tackled the question of where mathematics came from. It simply seems to "be there" - and while it might not be obvious to everyone, it's obvious to me that math is the OS on which the universe runs. The universe is fixated with numbers - speed and gravitational constants, numeric patterns found in nature (spheres, fractals etc), and of course, the inherent mathness of objects - two rocks next to two rocks is always four rocks. If you were in charge of building universes, you could make one in which the speed of light is changed, and it wouldn't really affect the workings all that much - it'd work like our universe but with properties of matter adjusted up or down. Now, change the value of pi, and the universe suddenly CAN'T work like ours - a sphere would no longer be a sphere, the shape of the universe would have to be twisted to allow the circumference of a planet to be the new pi times its diameter. Or maybe such a universe can't have circles at all - points equidistant from a single point could NEVER lie in a single plane. What would a planet orbit look like? What would an electron shell look like? Could molecular reactions even take place in such a universe?

    Where I'm going with this is, mathematics weren't born with the Big Bang. (Note that I don't mean the human understanding of mathematics - I mean the properties that our mathematics attempts to study. 2+2 was 4 long before humans learned to count - we just weren't there to give it a name.) Maybe I'm reading too much into it, but from where I sit, there's something about math - or whatever you can call this "OS on which the universe runs" that seems to have an awful lot in common with the math found in textbooks - that hints at an intelligence. Maybe math IS God (or as much of such a being as will fit in our universe). Maybe there's some great cosmic mechanism by which intelligent life from a completely nonmathematical (and self-spawned and matterless) universe created our universe entirely out of math as an experiment. Or by accident, as a result of their first experiments in creating math - maybe they don't know we're here! Maybe it really IS possible for our mathematical universe to arise from nothing - and either we ended up with this set of math rules by chance, or there's only one set of rules that works (but even THAT hints at a higher order). But you'll notice that Hawking, Einstein and others whose theories of the universe's origins depend on mathematics, don't have much of an answer as to where the underpinnings of mathematics came from.

    I find there is hope and beauty in math, and I did lousy in the subject in school. If math IS somehow a representation of God, though, it's fine by me - mathematics, at least to my eyes, hints at an intelligent pre-Big Bang creator that cared enough about his/her/its work to leave all that complexity just laying around, yet seems to have left absolutely zero messages for us in there. No Hebrew characters that spell out the Ten Commandments. No Godly alphabet staring out at us from a Newton's root-solving method graph. No Scientology tracts hidden in the digits of pi (well, not unless some numerologist decides to "find" one there - see last week's discovery of a number that "contains" the DeCSS code - with enough digits to choose from, one can "find" whatever one wants to find in pi). Absolutely NO policy statements anywhere to be found in math. In short, nothing in common with any religion's picture of God that I've yet found.

    Put it like this. The algorithm says to loop through z^2+C until C exceeds a threshold. It does NOT say to draw a circle-cardioid with an array of smaller circles around the edge, then repeat that shape but deform it nonlinearly and twist the "spine" on one end into all sorts of tendril shapes, repeat until done.

    You can do a Mandelbrot rendering in 10 lines of BASIC. It's not raytracing - it's more akin to discovering new digits of pi. z^2+c doesn't DRAW the Mandelbrot set - it reveals it.

    The orthodox view of science? Sorry, religion does not subscribe to ANY view of science. Science by its very nature is based upon observation. When new observations come to light, theories are be revised to reflect them. Religion (well all of the ones I'm familiar with) is based on eternal capital-T Truths. No amount of observation can disprove them or cause them to be revised. If something is observed that seems to contradict the Eternal Truths, then the observations are rejected.

    This having been said, most religions (even most forms of Christianity) don't seem to have a problem with the theory of evolution. They recognize it as a valid SCIENTIFIC principle. Which has nothing to do with valid RELIGIOUS principles. Observations - the best ones we have to date - indicate that life on Earth evolved from earlier forms. These observations say nothing about Eternal Truths. Nothing science says about human origins can contradict religion, and nothing religion says about human origins can contradict science. They're two very different things.

    The creationists seem to have confused science with Truth. In that way they have elevated science far beyond its humble position, and they want to place their Eternal Truths on the same lofty pedestal. But they are in for a disappointment. There is no pedestal. Scientific theories are revised all the time. Sometimes they're discarded altogether. No scientific theory occupies a pedestal as lofty as the one religion already has.

    The Biblical account of creation has endured for thousands of years. It has important moral messages that still resonate today. So do the creation stories of myriad other religions. They still have value even if observations indicate they didn't happen exactly as described. They're not science and they never will be. But so what?

    For me, I'll stick by science for things like the history of life on earth, the positions of the planets WRT to the sun, etc. It just seems to work better for me.

    I Am An Archaeologist, and I can tell you that at least for the relatively recent past (last 10000 years or so) radiocarbon dating works very well. It is not infallible, of course, and that is why any archaeologist who is responsible and has a decent budget will run multiple radiocarbon dates in a single context, to make sure you don't have a crazy outlier.

    Radiocarbon dating assumes only three things:

    1: that the rate of radioactive decay of the carbon-14 isotope has remained constant.
    2: that the carbon-14/carbon-12 ratio in the atmosphere was the same 'back then' as it is now (or was before we started setting off nuclear weapons blasts...),
    3: that the carbon in the sampe being dated was derived exclusively from atmospheric carbon dioxide.
    and, 4: that c-14 and c-12 are absorbed into plant tissues (and subsequently into animal tissues) at the same rate. That is, that plant A does not absorb proportionately more c-14 than does plant B, and so on up the food chain.

    The first assumption is a pretty safe one, since to doubt that would be to call into question very fundamental physical principals. I think the halflife of c-14 is about 5580 years, but that's just off the top of my head.

    The second assumption is obviously false, since cycles in the sun's radiation output affect the amount of carbon 14 produced in the upper atmosphere. For the recent past (4-5000 years) this has been corrected for by testing the c-14/c-12 ratio in precisely-dated (annual) tree rings in very old trees. So this is not a problem for recent times, and the difference even as much as 20000 years ago is probably not more than 1000 years or so. Again, not too much of a problem.

    The third and fourth assumptions are also problems, but the problems are understood and are being explored as we speak. Every year the correction methods for c-14 dating get more sophisticated. The important thing to remember, though, is that we are down to pretty fine points now. Any error introduced by failures of assumptions three and four would be in the range of a few centuries, max. Significant, but not enough to invalidate conclusions about the antiquity of human cultures, say.

    Sorry for the long post. I just wanted to point out tha while it is true that radiometric dating methods do make certain assumptions about conditions in the past, the limitation which these impose on the accuracy of the technique are well-understood and are taken into consideration by archaeologists and paleontologists.

    I also want to say that, like any scientific tool, radiometric dating is imperfect. But it is a hell of a lot better than simply guessing, or throwing up our hands. Do we want to study the past systematically and rigorously? If so, we must use these tools. If not, then, heck, the Bible was good enough for my grand-pappy.

    Do you understand the Mandelbrot set? I mean really understand how it works and how to compute it? And how it was conceived? I don't mean to be rude, but I really doubt you do.

    e always seemed like an amazing number, when I was taking math in high school. I mean, here was this number that that shows up everywhere, in all these equations in the world I wondered about it, and heard that it had something to do with calculus. And I always thought that it would be some mystery, like pi or something.

    But then I took calculus, and I learned how it really worked, and where it really came from, and I found out it was nothing. Just a number people put in their equations to make the math easier, (a lot easier). Similarly, PI, is just the arc-length integration of the equation of a circle, nothing spectacularly magical.

    Yes, the Mandelbrot set equation is pretty simple, z=z^2 + C where C is a complex constant. But, what you have to realize is how this equation is actually evaluated. It's not a simple y = f(x) function. C is a constant, and z is both a dependant and independent variable. So, how do you do it?

    Well, the fact is, it's a recursive function, starting out with z=0, and increasing with each loop, so, for, say, 0.8, you would do
    z = 0+0.8 = .8; now z = .8
    z = .8^2+ .8 = .64 + .8 = 1.44
    z = 2.07 + .8 = 2.87
    Now, once z gets past 2, it's all over, and C is not part of the Mandelbrot set. Some numbers will never get past 2. Not to complicated at all is it?

    Ok, now that we know what Z is, what's C? Well, if you're trying to graph the Mandelbrot set, then C is the pixel you're currently calculating. If it's in the set, draw it black, otherwise color the pixel based on how many times you had to loop to get past two.

    I have no idea why you would expect to see a circle, or some other kind of sinusoidal image.

    I have no idea why the image is self-similar. But I suppose that if I knew something about fractal theory, I would probably understand. And it would seem simple and unmagical to me.



    that demonstrates insane amounts of complexity that clearly don't come from the numbers you feed it.


    Well, the numbers are already complex right? Actually, 'the numbers you feed it' are every single complex number. Why wouldn't you expect infinite complexity from infinite numbers.

    Anyway, while it's interesting, I could probably come up with some formulas that produced 'beautiful' images if I worked at it for a while, but that wouldn't prove that I created the universe or anything, or that anyone else did.

    Of course, when you get right down to it, saying that the universe came about through random chance, isn't any more feasible then that it came about through a 'great intelligence' I'd be more apt to say that concepts such as random chance and intelligence had no meaning before the universe was formed, and all we can really prove is that we're thinking to hard.
