What a winning combination?
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. The first user who solved this task is Nílton Corrêa de Sousa.

MAGIC SQUARE: Calculate A-B-C
The aim is to place the some numbers from the list (19, 20, 21, 27, 28, 29, 42, 64, 65, 66, 76) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A-B-C. The first user who solved this task is Nílton Corrêa de Sousa.

Fear of alligators
While sports fishing off the Florida coast, a tourist capsized his boat. He could swim, but his fear of alligators kept him clinging to the overturned craft. Spotting and old beachcomber standing on the shore, the tourist shouted,"Are there any gators around here?!"
"Naw," the man hollered back, "they ain't been around for years!"
"Feeling safe, the tourist started swimming leisurely toward the shore.
About halfway there he asked the guy,"How'd you get rid of the gators?"
"We didn't do nothin'," the beachcomber said.
"The sharks got 'em."

George David BirkhoffBorn 21 Mar 1884; died 12 Nov 1944 at age 60.American mathematician,foremostof the early 20th century, who formulated the ergodic theorem. As the first American dynamicist, Birkhoff picked up where Poincaré left off, gaining distinction in 1913 with his proof of Poincaré's Last Geometric Theorem, a special case of the 3-body problem. Although primarily a geometer, he discovered new symbolic methods. He saw beyond the theory of oscillations, created a rigorous theory of ergodic behavior, and foresaw dynamical models for chaos. His ergodic theorem transformed the Maxwell- Boltzmann ergodic hypothesis of the kinetic theory of gases (to which exceptions are known) into a rigorous principle through use of the Lebesgue measure theory. He also produced a mathematical model of gravity. |
