    Sorry, but no. Have you ever looked at the source code Matlab produces? Every single line of code hooks into the Matlab library and does numerous checks for bounds, matrix dimensions, whatever. Even a simple for loop (for i=1:10) becomes a set of calls into the library. With that comes a general C compiler that cannot do the type of optimizations a Fortran compiler can make (due to aliasing), and the conclusion is clear. Compiled Matlab code is nowhere near the speed of Fortran.

    The factor 50 improvement you get with using the compiler, still leaves you with a large factor from actual Fortran performance. I've done some tests myself between compiled matlab and hand-written C that used the Matlab routines, and the C code beat the Matlab generated code by a factor of 20. Granted, that code used a lot of loops, but that was the reason I wanted the code to be compiled. And as for performance being irrelevant compared to quickness to write/maintain, this does not hold for numerically intensive code, where a slowdown smaller than 2 is probably acceptable, but not the orders of magnitude that Matlab seems to come with.

    Today I write my bottleneck code as external C programs (mex-files) for Matlab.

    Ok on Jericho. The point still stands. All historical evidence points to the fact that the Old Testament was a written down account of oral history, written down by jews in exile. So its oral history and very suspect in that.

    The New Testament, which is what Christianity is based upon, doesn't have these monumental miracles that might show in the historical records as the Old Testament has. It's merely the philosophy (ie: non-historical) of a particular person who was by a small set of people considered the Messiah. In that sense, Christianity and Buddhism are very comparable. The philosophies of the old and new testament are very different from eachother. The Old is an account of the history of a people, while the New presents a personal account of an individual.

    About the last part. What I was poorly phrasing there is indeed evidence of the miracles: where's the burning bush? In any case: what significance would it have if we found out that the Red Sea indeed was dry at a certain point? Or if we find a boat on the top of a mountain? There are numerous explanations for that, including a natural (or human induced) phenomenon that was construed to be of religious significance. Religion is a matter of faith, science a matter of reasoning. The two are not exclusive, even though I am a person of little faith.

    Actually, it goes a bit deeper than that. Darwinian evolution also predicted the existence of genes itself. Not their form or functioning, but it was a necessary part of the theory that there was a common carrier for inheritance of traits. So the actual key prediction of evolution was purely the existence of a DNA-like substance. This we take for granted nowadays, as its a fact, but scientist only started looking for it because of evolution theory. I think that since the discovery of this DNA, evolution theory has similar status as the theories of physics.

    No it doesn't. It addresses the point that if there is a particular document (string of genes) to be reached within a certain error limit, it is still impossible. My point was that there might be a wealth of documents, all giving rise to life. We've observed the outcome of one, but don't know about the magnitude of all. He talks about a minimum coding length of 256 (meaning a search space of 4^256). This assumes that the only coding space that can support life is DNA. How can he claim this? For all we know, life can arise from interactions of completely different molecules, which also has a tiny probability of success to be found. If the possibilities are numerous enough, they might simply add up.

    I grant the author his scepticism though, as I'm also not very convinced by science's forays into pre-biotic evolution. It's a tough problem, but I'm sure there's a rational explanation for it.

    The analogy was not meant to explain evolution, it was there to refute the challenge. The implicit assumption behind IC is that anything that cannot be broken apart cannot have been built. This is wrong and the arch example shows that. This means that the challenge is faulty and does not need to be taken seriously.

    My further statements about how evolution builds up and removes stuff is based on a few experiments I've done with artificial evolution (genetic programming), where indeed irreducibly complex programs evolve through mutation and selection and where a complete 'fossil' record was there to see that adding and removing stuff while retaining functionality indeed is possible. This doesn't necessarily mean that natural evolution does the same thing, but that wasn't what the analogy was used for.

    And dog, cow, human all use the same carrier for genetic material, DNA. The existence of such a carrier was predicted by evolutionary theory. Furthermore, evolutionary distance can now be quantified exactly. You have exactly 50% of the genes from your mom and 50% of your dad. You have more of your DNA in common with your monkey brother than with any other being except for your parents. 99.5% of your genes are shared with all humans on earth, 98% with the bonobo, our closest relative. Still a good 90% of your DNA is shared with all mammals, a good portion with reptiles, and so on and so on.

    Don't look at the fossil record, look at genomics. Evolution predicts that every living being ultimately has the same ancestor. More related animals have a more recent ancestor. Thus it predicts that the carrier of heritage should show similarities between species. This was stated long before this carrier, DNA, was discovered. Now looking at DNA we see that absurdly high percentages of the DNA are common in living (and fossilized) animals. As predicted. This DNA creates proteins and we see that although proteins in different animals are structurally slightly different, they still are functionally equivalent. Again predicted, but now through the neutral theory of evolution (in 1969, before efficient protein sequencers were available). Now drugs are being developed on the basis of similarity of function of different proteins. Without Evolutionary Theory there would not be a point in trying to use a protein from a chicken to test a drug for a human body. This can be done and all ultimately because of the predictive power of Evolutionary Theory.

    Actually irreducible complexity is easily refuted. It hinges on the fact that parts of organisms are so complex and interdependent, that if you take one thing out it ceases functioning. Hence, the IC proponents (who have died out by now) claim that the thing must have been created as a whole, as it cannot conceivably have been build up with small steps. And the ID is there.

    To refute this, simply take the construction of an arch of bricks. Humans have been capable of doing this for millennia. The nice thing about a brick arch is that it is irreducibly complex: take one brick out and the entire thing collapses. Unlike what the IC people claim, people don't put a ready made arch out of nowhere, they first build supporting structure, build the arch, and then remove the supporting structure. Something similar can easily happen in evolution. Lots of structure with limited functionality gets added and added, and lots of old superfluous structure gets removed. What you end up with is a 'irreducibly complex' structure where every part has a function and there's no clear indication how it was build. Simply because the supporting structure has been removed underway.

    Actually, Occam's razor itself has been mathematically formalized and sharpened in recent years. It's called the Minimum Description Length principle, which loosely states that the best theory is the one that minimizes (in bits) the length of the theory (in bits) plus the length of the exceptions to the theory (in bits). It is itself based on Bayes theorem, and is used in communication and learning theory, but can equally be applied to science. Unfortunately the thing itself depends on the Kolmogorov complexity and is thus uncomputable. Still, it does show that Occam's razor is a simplification of a deeper principle that is rooted in the axioms of mathematics. There's no religion there.

    Luckily many religions contradict eachother, so we can logically claim that they cannot conceivably be all true. Given that they all have the same amount of (historic) evidence behind them (none), one might actually be tempted to conclude that religion and truth are two completely different concept and should not be applied to eachother.

    Let's start with the scientific results that will actually give ID or creationism the status of a 'theory'. In proper scientific jargon, ID is at most conjecture, but actually an assertion. In scientific hierarchy of importance, this is the lowest of the low. In ascending order of scientific importance:

    Assertion: random guess

    Conjecture: more or less insightful claim on the basis of analysis

    Hypothesis: prediction of one or several facts. Still to be tested.

    Fact: more or less random observation that can be repeatedly observed. (If things are not supported, they fall down to the earth.)

    Law: very accurate equation tying together a number of facts. (Law of gravity).

    Theory: time-proven explanation of a wide range of facts. (Newtonian theory of mechanics includes the laws, but covers more ground.)

    As an atheist, I don't think the burden of proof is on me, but let's try to clarify this. Firstly, apart from an actual manifestation from God to myself and (preferably) the rest of the world, there is no logical way to disprove God. Please tell me, how would someone go about finding the evidence to the absence of:

    God

    The terrible snowman

Anything anyone conjures up that cannot be seen, or in other words, that is supernatural, cannot be disproven. Hence the burden of proof belongs to the theists. Despite millennia of attempts, this has failed miserably.

    What I do believe in is sceptical inquiry and reasoned weighting of arguments. Under this regime, the God hypothesis fails on several counts. Given the parent's remark about the agnostic reply, I'm sure we agree about this. I do however not accept equal opportunity agnosticism: God may or may not exist, with equal odds, and if it exists, it may or not may be a Christian, Jew, Islamic or Hindu God. That's simply too easy. The matter is too improbable for that.

    So I'll stick with my gospel: organized and quantified uncertainty. Call it doubt if you will. There is room for belief, but no room for faith. In this universe God is simply an exceedingly improbable possibility. Unlike agnostics, who implicitly assign equal odds to the existence or absence of a God, I'm an atheist: the likeliness of God existing I consider vanishingly small. For all practical purposes equal to zero.
