Really going from 1 to omega is no more special or difficult than going from 1 to 2. We just don't do it that often because it (apparently) isn't of much use. Transfinite numbers mostly don't express much more than finite numbers, or at least we haven't really found the use for them.
Irrational numbers don't really have digits. We just approximately display them using digits. Computers can also reason with irrational numbers (for example computer algebra systems can find irrational solutions of equations and express them precisely using terms like sqrt(n) ). With regards to nature, it seems that it in some ways it does use irrational numbers. Look at the earth and tell me that it has nothing to do with pi. It is true though that it doesn't use precise irrational numbers, but there doesn't seem to exist anything totally precise in nature at all - precision is just an abstraction. So according to your standard, clearly nature is infinite, because we can calculate using transfinite numbers. But of course this is a quite absurd conclusion, mainly because what we really mean by infinite has nothing to do with mathematically describable infinities like big ordinal or cardinal numbers. With regards to our intuitive notion of infiniteness, these are pretty finite, just like all other numbers. What we usually mean by infinite means more something like "(absolutely) boundless" or "incompletable" or "inexhaustable" or "unbound" or "absolute". All of these have little do with what we can measure or describe and thus it falls outside the realm of science or math. We can only observe that we can't find a boundary to space, or an end of time, or an end to math, but it is hard to say how this could be made precise or how to falsify it (I'd say it is impossible). My take on it is simply that the infinite is too absolute to be scrutinized. You can't falsify something which can't be conceived to be otherwise. It's literally impossible to imagine something like an absolute boundary (absolute finiteness). It is a nonsense concept. Nature simply is inherently infinite and the finite is simply an expression of the infinite, and is itself also the infinite (like the number 1 also has infinity "in it" 1=1*1*1*1*1*1*1*.... ). benjayk -- View this message in context: http://old.nabble.com/Simple-proof-that-our-intelligence-transcends-that-of-computers-tp34330236p34388985.html Sent from the Everything List mailing list archive at Nabble.com. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
