Unfortunately, that's not a very good link, phukraut. It actually deals with something else and, only in passing, touches briefly with what we are talking about. Here's a better
link . It's not perfect, either, but it is evidence that I'm not just making this up. It doesn't define greather than or equal to but I'm sure that when you see how equality (something it
does define) is defined, you will find my definition quite believable.
I assure you, I know what I am talking about.
I applaud you, Poloboy, for your reply (although I do question why you presented yourself with such authority, in the first place). The empty and rhetorical responses from the Politics forum have turned me cynical. They often ignore what was said and replace content with insults. It's very refreshing to not see that here.
Now, do you think you are in a position to understand the proof that |P(A)| > |A| ? It's
really cool but requires a firm understanding of these definitions, as well as mappings between sets...
Oh, and more to the point, there is an important proof that the set of real numbers is strictly bigger than the set of integers (despite how they're both infinite), but that proof is not too meaningful to someone just learning this stuff.
Also important, there is a simple proof that the non-negative integers have the same cardinality as the entire integers!
This stuff is pretty cool, eh?
Off topic, but cool...
