I Have A Question
A father and son went fishing one day. While they were out in the boat, the boy suddenly became curious about the world around him. He asked his father, "How does this boat float?
The father replied, "Don't rightly know son." A little later, the boy looked at his father and asked, "How do fish breath underwater?"
Once again the father replied, "Don't rightly know son." A little later the boy asked his father, "Why is the sky blue?"
Again, the father repied. "Don't rightly know son." Finally, the boy asked his father, "Dad, do you mind my asking you all of these questions?"
The father replied, "Of course not, you don't ask questions, you never learn nothin'."

Samuel Abraham GoudsmitDied 4 Dec 1978 at age 76 (born 11 Jul 1902).Dutch-born U.S. physicist who, with George E. Uhlenbeck, a fellow graduate student at the University of Leiden, Neth., formulated (1925) the concept of electron spin. It led to recognition that spin was a property of protons, neutrons, and most elementary particles and to a fundamental change in the mathematical structure of quantum mechanics. Goudsmit also made the first measurement of nuclear spin and its Zeeman effect with Ernst Back (1926-27), developed a theory of hyperfine structure of spectral lines, made the first spectroscopic determination of nuclear magnetic moments (1931-33), contributed to the theory of complex atoms and the theory of multiple scattering of electrons, and invented the magnetic time-of-flight mass spectrometer (1948). |
MAGIC SQUARE: Calculate A+B+C
The aim is to place the some numbers from the list (2, 14, 16, 21, 30, 34, 36, 41, 47, 49, 54, 79) 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.
