If 703ab + 7177c = 14b15a find number abc. Multiple solutions may exist.
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.
Look at the series (9458, 261440, 170, ...), determine the pattern, and find the value of the next number!

Heinrich Hertz

Born 22 Feb 1857; died 1 Jan 1894 at age 36. Heinrich Rudolf Hertz was a German physicist who was the first to broadcast and receive radio waves. He studied under Kirchhoff and Helmholtz in Berlin, and became professor at Bonn in 1889. His main work was on electromagnetic waves (1887). Hertz generated electric waves by means of the oscillatory discharge of a condenser through a loop provided with a spark gap, and then detecting them with a similar type of circuit. Hertz's condenser was a pair of metal rods, placed end to end with a small gap for a spark between them. Hertz was also the first to discover the photoelectric effect. The unit of frequency - one cycle per second - is named after him. Hertz died of blood poisoning in 1894 at the age of 37.

Women Are Evil

The CIA had an opening for an assassin.
After all the background check, interviews, and testing were done, there were three finalists. Two men and a woman. For the final test, the CIA agents took one of the men to a large metal door and handed him a gun.
"We know that you will follow your instructions, no matter what the circumstances. Inside this room, you will find your wife sitting in a chair. Kill Her!!!"
The man said, "You can't be serious. I could never shoot my wife."
The agent said, "Then you're not the right man for this job. Take your wife and go home."
The second man was given the same instructions. He took the gun and went into the room. All was quiet for about five minutes. Then the man came out with tears in his eyes. "I tried, but I can't kill my wife."
The agent said, "You don't have what it takes. Take your wife and go home."
Finally, it was the woman's turn. She was given the same instructions, to kill her husband. She took the gun and went into the room. Shots were heard, one shot after another. They heard screaming, crashing, banging on the walls. After a few minutes, all was quiet. The door opened slowly and there stood the woman. She wiped the sweat from her brow.
"This damn gun is loaded with blanks", she said. "I had to beat him to death with the freaking chair."
Moral of the story: Women are evil. Don't mess with them
