Christian Goldbach

Died 20 Nov 1764 at age 74 (born 18 Mar 1690).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.]

A guy is sitting at a bar ...

A guy is sitting at a bar in a skyscraper restaurant high above the city. He's slamming tequila left and right. He grabs one, drinks it, goes over to a window and jumps out. The guy who was sitting next to him couldn't believe that the guy had just done that. He was more surprised when, ten minutes later, the same guy, unscathed, comes walking back into the bar and sits back down next to him. The astonished guy asks "How did you do that? I just saw you jump out that window and we're hundreds of feet above the GROUND!!!". The jumper responds by slurring, "Well, I don't get it either. I slam a shot of tequila and when I jump out the window, the tequila makes me slow down right before I hit the ground. Watch." He takes a shot, slams it down, goes to the window and jumps out. The other guy runs to the window and watches as the guy falls until right before the ground, slows down and lands softly on his feet. A few minutes later, the guy walks back into the bar. The other guy has to try it too, so he orders a shot of tequila. He drinks it and goes to the window and jumps. As he reaches the bottom, he doesn't slow down at all....SPLAT!!!!!! The first guy orders another shot of tequila and the bartender says to him, "You're really an jerk when you're drunk, Superman."
