    Okay, so I've been taking this new class at school at the start of a new semester, and it's really cool. Basically we work for the school's newsletter, learn how reporters write their notes/articles, how they can talk so fast and calm on TV, and how to rate/review different things, such as cafes or video gams! So, this class inspired me to create my own personal newsletter which I will post on each of the Wiki's I'm a member at, called "Harley's Hub!". Featured in this newsletter will be stories on different Wikis, ratings of different Wikis, polls about different Wikis, and stuff like that. BUT, here's the good stuff. You may submit your Wiki to either get a lead story, a spot in the review section, or a slot in the poll section! Just tel…

    3 Mathematical Conundrums

    December 24, 2011 by Keo5

    I stubled across 3 false proofs, see if you can find the errors.


    • X=Y
    • X^2=X*Y
    • X^2-Y^2=X*Y-Y^2
    • (X+Y)*(X-Y)=Y*(X-Y)
    • X+Y=Y
    • 2Y=Y
    • 2=1

    • X=0.99999...
    • 10X=9.99999...
    • 10X-X=9.99999...-X
    • 9X=9
    • X=1
    • 0.99999...=1

    This one is a word problem. Imagine a square with sides of 4, and therefore a perimiter of 16. Cut corners, and the perimiter stays the same. See below for a visual.


    • HHHHHHHHHH
    • HHHHHHHHHH
    • HHHHHHHHHH
    • HHHHHHHHHH
    • HHHHHHHHHH
    • HHHHHHHHHH


    The perimeter of the above shape is equal to the perimeter of the shape below. (_ equals negative space)

    • ____HHHH____
    • ____HHHH____
    • HHHHHHHHHH
    • HHHHHHHHHH
    • ____HHHH____
    • ____HHHH____

    Repeat to infinity. Square becomes a circle

    • 16=Pi*(2)^2

    Therefore, Pi equals 4


    That's all folks!
