Unexpected cold snaps had destroyed the buds on a man's peach tree for two years in a row. This spring, he was ready. He replanted the sapling in a large box, mounted it on wheels, and put the tree in the garage whenever the temperature dropped.
One warm April day, the man was wheeling the tree out into the yard, and he stopped to give his dog a drink from the garden hose.
A neighbor watched the scene with amusement. "Frank," he finally commented, "you're the only man I know who walks his tree and waters his dog!"

MAGIC SQUARE: Calculate A*B*C
The aim is to place the some numbers from the list (1, 2, 4, 15, 16, 18, 28, 29, 31, 67, 72, 91) 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 Nílton Corrêa De Sousa.

Hermann MinkowskiDied 12 Jan 1909 at age 44 (born 22 Jun 1864). German mathematician who developed the geometrical theory of numbers and who used geometrical methods to solve difficult problems in number theory, mathematical physics, and the theory of relativity. By 1907, Minkowski realised that the work of Lorentz and Einstein could be best understood in a non-euclidean space. He considered space and time, which were formerly thought to be independent, to be coupled together in a four-dimensional "space-time continuum". Minkowski worked out a four-dimensional treatment of electrodynamics. His idea of a four-dimensional space (since known as "Minkowski space"), combining the three dimensions of physical space with that of time, laid the mathematical foundation of Albert Einstein's general theory of relativity. |
