MAGIC SQUARE: Calculate A+B+C
The aim is to place the some numbers from the list (2, 3, 4, 8, 9, 10, 14, 25, 26, 30, 44, 67) 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.

Ballpen in space
When NASA first started sending up astronauts, they quickly discovered that ballpoint pens would not work in zero gravity.
To combat the problem, NASA scientists spent a decade and $12 billion to develop a pen that writes in zero gravity, upside down, underwater, on almost any surface including glass and at temperatures ranging from below freezing to 300 C.
The Russians used a pencil.
Find number abc
If a3554 - c58c3 = 4bb4c find number abc. Multiple solutions may exist.

Stanley Keith RuncornBorn 19 Nov 1922; died 5 Dec 1995 at age 73.British geophysicist Southport, Lancashire, who was the first to discover evidence of the periodic polar reversals of the Earth's magnetic field. In the 1950s he was a pioneer in the fledgling discipline of paleomagnetism, or remanent magnetism, the study of the residual magnetism. He also made substantial contributions to various fields, including convection in the Earth and Moon, the shape and magnetic fields of the Moon and planets, magnetohydrodynamics of the Earth's core, earth currents, changes in the length of the day and polar wandering, continental drift and plate tectonics. He was murdered, aged 73, when he disturbed a thief in his motel room in San Diego, while on a US lecture tour. |
