MAGIC SQUARE: Calculate A-B-C
The aim is to place the some numbers from the list (10, 11, 12, 20, 21, 22, 27, 32, 55, 56, 57, 72) 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 5b95a - c005c = ab89b find number abc. Multiple solutions may exist.
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.
Blonde gets haircut
A blonde went to a beauty salon to get a haircut. When the beautician approached the chair where the blonde was waiting, she noticed that she was wearing a walkman. The beautician took the blonde to her styling booth. She asked the blonde, "Please take off the walkman so I can cut your hair." The blonde replied, "I can't do without it, just cut around it."
The beautician shook her head in disbelief and started cutting. A few minutes later the beautician stopped and asked the blonde, "I just can't cut your hair properly while you are wearing that walkman. Please take it off." The blonde replied, "I just can't live without it, cut around it please." The beautician started cutting again and finally had had enough.
The beautician reached down and pulled the earphones from the walkman off the blonde. Just as she did so the blonde froze, then fell out off the chair and on to the floor. The staff at the salon rushed to her aid only to discover she was stone dead. All were stunned! The beautician lifted the earphones to her ear to listen to what was so important to the blonde.
In a soft but commanding voice she heard, "Breathe in.......... Breathe out............ Breathe in.......... Breathe out............ Breathe in.......... Breathe out............"

Philipp ForchheimerDied 2 Oct 1933 at age 81 (born 7 Aug 1852).Austrian hydraulic engineer who made significant studies of groundwater hydrology. Early in his academic career, he worked on problems of soil mechanics. Later, he turned to hydraulic problems, establishing the scientific basis of the discipline by applying standard techniques of mathematical physics - in particular Laplace's equation - to problems of groundwater movement. Laplace's equation had already been well developed for heat flow and fluid flow. Forchheimer extended the preexisting mathematical theory to calculations of groundwater flow. He was also the first to both mathematically and experimentally examine the features of dambreak waves in a rectangular channel (with his PhD student Armin Schoklitsch).« |
