English mathematician G.H. Hardy (or possibly Bertrand Russell, depending on who you believe) was said to have made this interesting proof (or one much like it):
Assume 0=1.
Then 1=2, by adding 1 to both sides of the equation.
The Pope and I are two people (this is obvious).
Then The Pope and I are one person, since 1=2.
Then I am the Pope, since we are the same person.
This is just a byproduct of the fact that a false proposition implies anything. |
