At the conclusion of the sermon...
At the conclusion of the sermon, the worshippers filed out of the sanctuary to greet the minister. As one shook the minister’s hand, he said, “Thanks for the message, Reverend. You know, I bet you’re smarter than Einstein. ”Beaming with pride, the minister said, “Why, thank you, brother!” As the week went by, the minister began to think about the man’s compliment. The more he though, the more the wondered why anyone would deem him smarter than Einstein. So the following Sunday he asked the man, “Exactly what did you mean that I must be smarter than Einstein?” The man replied, “Well, Reverend, they say that Einstein was so smart that only ten people in the entire world could understand him. But Reverend, no one can understand you.”

Ernest BrownBorn 29 Nov 1866; died 22 Jul 1938 at age 71.Ernest (William) Brown was a British astronomer who devoted his career to the theory of the Moon's motion and constructing accurate lunar tables. His theory took account of "the gravitational action of every particle of matter which can have a sensible effect on the Moon's motion," some 1500 terms. He then determined the numerical values of the constants by analyzing 150 years of Greenwich observations, and computed tables accurate to 0.01 arcsec. After 30 years of work, Brown published his lunar tables Tables of the Motion of the Moon in 1919. In 1926 Brown published a paper in which he ascribed fluctuations in the Moon's motion to irregular changes in the Earth's period of rotation, which has subsequently proved correct. |
MAGIC SQUARE: Calculate A*B-C
The aim is to place the some numbers from the list (4, 5, 12, 13, 14, 17, 21, 31, 32, 39) 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.
