I saw this and thought of you people, for some reason.
----- Forwarded message ----- So I went and found this on a page of math "humor", in particular of bogus proofs. This one ain't bad; a nice variant to a classic. The aim is to prove that 1 = 2. Notice the following: 1 = 1^1 = 1 2 + 2 = 2^2 = 4 3 + 3 + 3 = 3^2 = 9 4 + 4 + 4 + 4 = 4^2 = 16 and in general: x + x + ..... + x = x^2 \___ x times ___/ Derive in place: 1 + 1 + ..... + 1 = 2 x \___ x times ___/ 1 * x = 2 x Simplify by x which is not zero, 1 = 2. Note the formula is valid for pure fractionals too, for example: 0.05 + 0.05 + 0.05 + 0.05 + 0.05 = 0.01 * (5 + 5 + 5 + 5 + 5) = 0.01 * 5^2 = 0.05 ^2 = 0.25 and thus it is valid for any real number x because we can always write x as a sum of a pure integer u and a pure fractional v: x = u+v. For example x=3.8 => u=3 and v=0.8. So we are not deriving in a discrete space, think somewhere else. ----- End forwarded message ----- -- real minaret
