MAGIC SQUARE: Calculate A+B+C
The aim is to place the some numbers from the list (5, 7, 14, 15, 16, 25, 26, 27, 28, 29, 30) 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 Nasrin 24 T.

I finally got one over
The other day, Louise and I got into some petty argument. (I say it was petty. She would have said it was Armageddon.) As is our nature, neither of us would admit the possibility that we might be in error.
To her credit, Louise finally said, 'Look. I'll tell you what. I'll admit I'm wrong if you admit I was right.'
'Fine.' I said.
She took a deep breath, looked me in the eye and said, 'I'm wrong.'
I grinned and replied, 'You're right.'
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. The first user who solved this task is Nasrin 24 T.

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).« |
