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!'

Parity nonconservation proposedIn 1956, The Physical Review published a paper by Tsung Dao Lee and Chen Ning Yang on the Question of Parity Conservation in Weak Interactions. They addressed an issue that had long been believed, but for which there had been no experimental support. Yet, there existed a Theta-Tau Puzzle (C.F. Powell, 1949) in the disintegration of certain cosmic ray particles via the nuclear weak force. Lee and Yang believed this was because of parity violation, which contradicted the generally accepted "law" of conservation of parity. They proposed a study of experiments involving weak interactions. Chien-Shiung Wu validated non-conservation of parity on 27 Dec 1956 in their suggestion to study beta decay of cobalt-60.« |

MAGIC SQUARE: Calculate A+B-C
The aim is to place the some numbers from the list (5, 7, 8, 20, 22, 23, 24, 56, 58, 59, 81) 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.
