Gary and Martin were standing at the urinals in a public lavatory, when Gary glanced over and noticed that Martin's penis was twisted like a corkscrew. "Wow," Gary said. "I've never seen one like that before."
"Like what?" Martin said.
"All twisted like a pig's tail," Gary said.
"Well, what's yours like?" Martin said.
"Straight, like normal," Gary said.
"I thought mine was normal until I saw yours," Martin said.
Gary finished what he was doing and started to give his old boy a shakedown prior to putting it back in his pants. "What did you do that for?" Martin said.
"Shaking off the excess drops," Gary said. "Like normal."
"&%$#@ !," Martin said. "And all these years I've been wringing it."
Which is a winning combination of digits?The computer chose a secret code (sequence of 4 digits from 1 to 6). Your goal is to find that code. Black circles indicate the number of hits on the right spot. White circles indicate the number of hits on the wrong spot.
Gregori Aleksandrovich MargulisBorn 24 Feb 1946.Russian mathematician who was awarded the Fields Medal in 1978 for his contributions to the theory of Lie groups, though he was not allowed by the Soviet government to travel to Finland to receive the award. In 1990 Margulis immigrated to the United States. Margulis' work was largely involved in solving a number of problems in the theory of Lie groups. In particular, Margulis proved a long-standing conjecture by Atle Selberg concerning discrete subgroups of semisimple Lie groups. The techniques he used in his work were drawn from combinatorics, ergodic theory, dynamical systems, and differential geometry.
