We noticed that all the waiter...
We noticed that all the waiters in this New York restaurant carried two spoons in their vest pocket. Naturally, we were curious. We asked a waiter why.
'Sir, as a result of an efficiency study by the management, it was determined that the most frequently dropped silverware item was a spoon. Therefore, all the waiters carry two spoons so that the item can be instantly replaced.' As he was explaining that we noticed a string hanging out of the fly of his pants. So, we asked about that.
'Sir, that's another efficiency study result. When we have to go to the bathroom, we use the string to pull ourselves out and aim. Therefore, we do not have to stop to wash our hands.' We replied, 'I understand how you can get yourself out and aim, but how do you get yourself back in.' 'Well,' replied the waiter, 'I don't know about the other guys, but I use the two spoons!'

MAGIC SQUARE: Calculate A-B*C
The aim is to place the some numbers from the list (10, 11, 13, 23, 24, 26, 29, 30, 32, 64, 95) 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.

Robert Sanderson MullikenDied 31 Oct 1986 at age 90 (born 7 Jun 1896). American chemist and physicist who received the 1966 Nobel Prize for Chemistry for “fundamental work concerning chemical bonds and the electronic structure of molecules.”In 1922, he first suggested a method of isotope separation by evaporative centrifuging. Thereafter, most of his research career was concerned with the interpretation of molecular spectra and with the application of quantum theory to the electronic states of molecules. With Friedrich Hund, he developed the molecular-orbital theory of chemical bonding, based on the idea that atomic orbitals of isolated atoms become molecular orbitals, extending over two or more atoms in the molecule. He also made major contributions to the theory and interpretation of molecular spectra. |
