Not All Infinities Are The Same Size.......

[ToraToraTora]

Now, I've seen before how some infinities are bigger than others on maths docs etc but this explains it very well.

Thought it might interest those that visit the science section.

Very interesting - and clearly explained too.

This is called Hilbert's Hotel

John Barrow also uses it - and has written a laymans book on it - Infinity (*) - Does it go anywhere near Cantor's theorem ?

(*) and yes incase anyone was wondering he IS the descendant of the Isaac Barrow really did say 1665 - "I shouldnt be Lucasian prof of mathematics: Mr Newton should"

pretty incredz huh?
