It was three o'clock in the m...
It was three o'clock in the morning, and the receptionist at a posh hotel was just dozing off, when a little old lady came running towards her, screaming.
"Please come quickly!" she yelled, "I just saw a naked man outside my window!!!"
The receptionist immediately rushed up to the old lady's room.
"Where is he?" asked the receptionist.
"He's over there," replied the little old lady, pointing to an apartment building opposite the hotel.
The receptionist looked over and could see a man with no shirt on, moving around his apartment. "It's probably a man who's getting ready to go to bed," she said reassuringly. "And how do you know he's naked, you can only see him from the waist up?"
"The dresser, honey!" screamed the old lady. "Try standing on the dresser!"

Felix BlochBorn 23 Oct 1905; died 10 Sep 1983 at age 77.Swiss-born American physicist who shared (with independent discoverer, E.M. Purcell) the Nobel Prize for Physics in 1952 for developing the nuclear magnetic resonance (NMR) method of measuring the magnetic field of atomic nuclei. He obtained his PhD under Werner Heisenberg in 1928, then taught briefly in Germany, but as a Jew, when Hitler came to power, he left Europe for the USA. Bloch's concept of magnetic neutron polarization (1934) enabled him, in conjunction with L. Alvarez, to measure the neutron's magnetic moment. During WW II he worked on the atomic bomb. Thereafter, Bloch and co-workers developed NMR, now widely used technique in chemistry, biochemistry, and medicine. In 1954 he became the first director of CERN. |

MAGIC SQUARE: Calculate A*B*C
The aim is to place the some numbers from the list (6, 7, 9, 10, 15, 18, 19, 28, 31, 32, 38, 96) 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.
