Donald Knuth On NPR

StratoFlyer writes "This morning, NPR is running an interview with Donald Knuth titled Donald Knuth, Founding Artist of Computer Science. The persistence of this man is extraordinary, if not heroic. RealPlayer and MediaPlayer feeds will be available at 10am EST, according to the NPR.org site." Indeed they are.

    Knuth came across as charming, and funny, and classically geeky, re-computing the size of a piece of paper necessary for making a five-pointed star with one cut and rattling off the equation behind it, or describing his mental process behind brushing his teeth, but also clearly grounded in continuing scholarly work.

    The narrator also mentions he's "abandoned email." Interesting detail, especially as I contemplate the 995 messages in my inbox this morning (80% spam, 19% mailing lists), I am starting to wonder why I don't get around to it myself.

    For me, Knuth's belief in a god does not have the same authority as his ability to prove the efficiency or convergence rate of an algorithm. Mathematics and other branches of science are a rational and testable form of knowledge. Belief in a diety must ultimately come down to a personal choice -- a leap of faith -- beyond the realm of rational.

    No, actually, it's not. Having an open mind is one thing, having a mind so open your brain falls out is quite another.

    I have heard this quip before, but you are mis-using it when applying it to scientific and critical thinking. The original quote is making reference to people who will BELIEVE anything. Scientists must consider all possibilities until proven wrong.

    This means invisible elephants MIGHT exist. However, as there is no proof that they do, and no theory for why they might, a scientist will not ponder the question long.

    This also means wormholes might exist, and even though there is no evidence of them, scientists are open to the possibility because they'd fit in with other theories that are out there, and so they do consider these.

    If someone told you there were invisible pink elephants in his back yard, you would keep an open mind about that and not think that maybe your buddy had flipped his lid? Even after going out and pointing out to your buddy that these elephants left no tracks, dung, or anything else behind to show their presence, or that you could walk over every inch of his back yard and not run into one, you would still choose not to disbelieve him if he insisted they existed and were there? Seriously? That's not science or critical thinking, that's just being foolish.

    Would I disbelieve him? Of course. Would I go further and, without proof, tell him there is no way on Earth? For pink elephants -- probably so. For something much more mysterious, why bother?

    I know you keep wanting to bring up these pink elephants, however the reality is that agnostics do not worry themselves over the question of God. There is neither proof or disproof, and so it is an interesting but pointless thought experiment.

    For someone to see a lack of evidence and firmly come down against something is just as bad as firmly coming down in favor of it. This is why people often call Atheism a religion.

Not that they need to start believing themselves, but that they should admit that belief in God is not evidence of stupidity.

    In terms of the scientific method, the difference between atheists and agnostics is their view of the theory "God exists". Atheists consider this a testable theory, and the lack of convincing evidence supporting that theory (or any supernatural theory, for that matter) means to them that there is room to doubt that theory. Atheism does not imply a blind rejection of God, nor does it have anything to do with the rejection of organized religion. However, atheism is frequently associated with scientists, who frequently also reject organized religion, so atheism has gained that connotation by accident. Also, some very loud people who call themselves atheists blindly reject God without consideration - these are just zealots of a different nature.

    Agnosticism is very similar to atheism with one key difference: agnostics believe that the theory "God exists" is not testable, and is thus disinteresting from the point of view of science.

    Some view this as the "easy way out" of the deist question, but it's actually just another way of looking at the question from a scientific perspective. A theory must be testable in order for it to be verified or rejected through experiments. Theories which are not testable are nothing more than nice ideas or speculation from the perspective of science.

    Most atheists and agnostics are not openly hostile to organized religion, but some are, and the rest of us get a bad name because of these loud few. Please do not associate atheism or agnosticism with anything more than differing opinions on how the scientific method should be applied to the question of God. Both atheism and agnosticism are closely related and in a different class from all other beliefs regarding God, in that they both reject faith as a way to find truth of God's existence or lack of existence.
