Fun math puzzle
Puzzle #3:
Is .999999... = 1? If so prove it. This has a few proofs, and some are simple enough to show someone in junior high.

;) the easy one:
X=0.9999...
=> 10X-9=X
=> 10X-X=9
=> 9X=9
=> X=1
I already told this joke to Reza, but adding to the blog for posterity...
"A mathematician was trying to explain the concept of limits to an engineer. His analogy was this:
Suppose you have a beautiful naked woman tied to a post, and every time you take a step toward her you can traverse only 1/2 the distance between you and the naked lady. Will you ever reach her?
The engineer replied (with a good ol boy Texan accent; he was an A&M grad I think :) )
"I don't care, as long as I get close enough to do some real good""
ice story!
