Talk:Infinity

From Esolang

Infinity isn't a number. It can only occur in a numerical theory in the form of a limit (either as Lim or implicitly in an integral). To say that something is infinite is the same as saying its size is unbounded, except that 'unbounded' can include objects whose size vary over time. And as the size of an unbounded object can tend to infinity over time, it doesn't help in construction.

Furthermore each language requiring an infinite store is equivalent in behaviour to a language requiring a store that can grow without limit but is finite at any particular time and initialised when needed (except if the initialisation function is non-computable, in which case the original language could never be implemented according to the Church-Turing Thesis).

Sorry to get a bit technical, but I think this entry needs rewording (keep the humour though :-).

Your definition of 'number' is rather inflexible, then. :) Infinity is not a real number, of course, but I see nothing wrong with calling it a number. lament (a Math major in the making)

"A finite number is one that you can imagine; infinity is, therefore, unimaginable."

This isn't entirely true, of course; really, a better definition of "imagine" is needed. --Ihope127 01:05, 16 Sep 2005 (GMT)
