Simple examples for it are the non-repeating numerals You're clueless about mathematical reasonings and should not have proclaimed anything "self evident". "Non-repeating numerals" can't be examples (let alone simple ones) of the purported truth of the Axiom of Infinity: the 2 are not even of the same language! Learn basic facts about mathematical logic first, before uttering and proclaiming "self evident" things that you're clueless about such as "axiom of infinity is true", or mathematical truths exist in the real world. -- --------------------------------------------------- Time passes, there is no way we can hold it back.

It is computable to get ANY numeral of root 2. Is it not computable to get ALL numerals of root 2. You could shift your definition of computable admittedly but the problem remains intractable. Herc

This is all obvious. a) No actual "in life" measurement is exact, there is always a measurement error. 4 miles east + 4 miles east = 9 miles east +/- some measurement error, which is always uncertain past some number of significant digits. Which should remind you of the issue of accuracy vs. precision, the misunderstanding of which leads to such absurdities as claiming that a 3.45 grade point average is better than a 3.44 average. Ironically, it's the truths of "regular arithmetic" that enable one to understand why these numbers are absurd. b) 4 miles east plus 5 miles west is not 9 miles northwest. c) 4 pints of water plus 5 pints of ethanol do not produce 9 pints of vodka.
