I was watching the London Marathon and saw one runner dressed as a chicken and another runner dressed as an egg...
I thought, "This could be interesting."
Christian GoldbachBorn 18 Mar 1690; died 20 Nov 1764 at age 74.Russian mathematician whose contributions to number theory include Goldbach's conjecture, formulated in a letter to Leonhard Euler dated 7 Jul 1742. Stated in modern terms it 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 made another conjecture that every odd number is the sum of three primes, on which Vinogradov made progress in 1937. (It has been checked by computer for vast numbers, but 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.] |
