Appropos of nothing, here’s an entry from a polymath professor that blew my mind. It’s a small thing, really, but something I’ve never thought about. 0.99999… (infinitely repeating) is equal to 1. Not “close enough” to 1, but equal to 1.

It’s wild. Check it out.

    He’s wrong. Because I say so.

    Hot damn, that’s whacky.

    It really is. Like the Monty Hall problem.

    Hehe, known about this for a while. Post it on absolutely any forum and see how quickly the thread reaches 100 pages, it’s fun :)

    Why can people not accept this but accept 2/4 = 1/2? Of course, I am the total math geek, and was in deep discussion one day after work with my boss and another manager saying things like “That’s not a partition” and “Do they not understand Venn Diagrams?” referring to rules that were proposed for a data conversion.

    You should have a bash at the jet-plane-on-the-conveyor-belt problem, see how that bakes your noodles.

    …which would be here along with a solution.

    This is, I mean WWJD? He’d say its all a lie!! J/K. That’s cool, I wouldn’t have thought of it on my own, I would’ve just said…. “close enough for me”
