[quote=@whizzball1] The point is to think about them, and improve yourself figuring them out. At least, that was my goal in solving that puzzle. I'm a better thinker for it. Although, according to the Wikipedia page, the point of the paradox was "to illustrate certain counterintuitive properties of infinite sets." Namely, that even all of infinity was filled, you could still fit in another element, or you could fit in infinite new elements, or you could even add infinite groups of infinite elements, and mathematically it would actually work (with empty elements left over!). [/quote] That's not even a puzzle. That's a mathematical system problem with fluff all around it.
