Not Infinity!

Posted by MacDood
Many mathematicians, math geeks, and other strange beings, have jabbered on and on about "infinity", infinite sets, and what-not. They've said a lot about what infinity is; but today, I'd like to tell you what infinity is not. This article hopes to clear up some common confusions and misconceptions surrounding "infinity" which may have led the less mathematically-inclined to think that math is contradictory and confusing. Hopefully, it will also introduce a bit of what infinity is, so that normal people can understand it without their brains turning into a pretzel1. A subsequent article will delve deeper into the subject and clear up even more misconceptions that people may have about infinity. 1Shaped like ∞. [Kuro5hin.org]
