What do you call a belt made out of hundred dollar bills?
A waist of money.
Goldbach's conjectureIn 1742, the Russian mathematician Christian Goldbach dated a letter to Leonhard Euler in which he presented his famous conjecture. Stated in modern terms, Goldberg's conjecture proposes that “Every even natural number greater than 2 is equal to the sum of two prime numbers.”It has been checked by computer for vast numbers - up to at least 4 x 1014 - but still remains unproved. Goldbach also studied infinite sums, the theory of curves and the theory of equations.«[Image: Letter to Euler, in which Goldbach presented his conjecture.] |
