MAGIC SQUARE: Calculate A+B-C
The aim is to place the some numbers from the list (11, 15, 16, 18, 19, 20, 22, 57, 58, 60, 69) 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.
Find number abc
If c3ba3 - 2cccc = a3bab find number abc. Multiple solutions may exist.
The Statue
A woman was in bed with her lover when she heard her husband opening the front door.
"Hurry!" she said. "Stand in the corner." She quickly rubbed baby oil all over him and then she dusted him with talcum powder. "Don't move until I tell you to," she whispered. "Just pretend you're a statue."
"What's this honey?" the husband inquired as he entered the room.
"Oh, its just a statue," she replied nonchalantly. "The Smiths bought one for their bedroom. I liked it so much, I got one for us too."
No more was said about the statue, not even later that night when they went to sleep. Around two in the morning the husband got out of bed, went to the kitchen and returned a while later with a sandwich and a glass of milk. "Here," he said to the 'statue', "eat something. I stood like an idiot at the Smith's for three days and nobody offered me so much as a glass of water".
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.
Boris Borisovich GolitsynDied 17 May 1916 at age 54 (born 2 Mar 1862).Prince Boris Borisovich Golitsyn was a Russian physicist and seismologist who developed scientific methods and instruments for earthquake observations and mineral prospecting. His early studies were in molecular physics, mathematical physics and electromagnetism, From 1899 his interests turned to seismology. In 1906, he invented the first effective electromagnetic seismograph and continued to improve it. It had a pendulum carrying a coil of insulated wire around a magnetic core fixed to the ground. The small current generated in the coil by relative motion caused by earth tremors is amplified to operate a pen recorder. The part of the Earth's mantle at a depth of 400-800 km, in which seismic waves travel rapidly, is named the Golitsyn layer in recognition of his work.«[Name also spelled Galizin ot Golicyn. Death given as 17 May in EB, but 16 May in DSB. Old style dates on the Russian calendar of that time: b 18 Feb; d 4 May.] |
