Find the right 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.

MAGIC SQUARE: Calculate A*B+C
The aim is to place the some numbers from the list (8, 11, 18, 23, 26, 33, 36, 39, 45, 46, 68, 86) 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.

Photographer
A photographer for a national magazine was assigned to take pictures of a great forest fire. He was advised that a small plane would be waiting to fly him over the fire.
The photographer arrived at the airstrip just an hour before sundown. Sure enough, a small Cessna airplane was waiting. He jumped in with his equipment and shouted, "Let's go!" The tense man sitting in the pilot's seat swung the plane into the wind and soon they were in the air, though flying erratically.
"Fly over the north side of the fire," said the photographer, "And make several low-level passes."
"Why?" asked the nervous pilot.
"Because I'm going to take pictures!" yelled the photographer. "I'm a photographer, and photographers take pictures!"
The pilot replied, "You mean you're not the flight instructor?"

Stanislaw M. UlamBorn 13 Apr 1909; died 13 May 1984 at age 75.Polish-American mathematician who played a major role in the development of the hydrogen bomb at Los Alamos. He solved the problem of how to initiate fusion in the hydrogen bomb by suggesting that compression was essential to explosion and that shock waves from a fission bomb could produce the compression needed. He further suggested that careful design could focus mechanical shock waves in such a way that they would promote rapid burning of the fusion fuel. Ulam, with J.C. Everett, also proposed the "Orion" plan for nuclear propulsion of space vehicles. While Ulam was at Los Alamos, he developed "Monte-Carlo method" which searched for solutions to mathematical problems using a statistical sampling method with random numbers. |
