Enter a Password
A woman was helping her husband set up his computer, And at the appropriate point in the process. She told him that he would now need to enter a password, something he could remember easily and will use each time he has to log on.

Infrared photographsIn 1931, the first U.S.short-exposure infrared photograph taken of a large group of people in apparently total darkness was taken in Rochester, NY at the Eastman Kodak Research Laboratories. They were in a room that was flooded with invisible infrared light (waves 700 to 900 nanometers long, beyond the red end of the visible spectrum). A group of 50 people visiting the laboratory was photographed on a new photographic emulsion sensitive to infrared. Since then, scientists have made use of infrared photography in medical applications and aerial photography. Since plant chlorophyll reflects infrared rays more intensely than other green materials, infrared photos yield a precise indication of where vegetation is present on the ground. |
MAGIC SQUARE: Calculate A*B+C
The aim is to place the some numbers from the list (8, 10, 15, 18, 20, 25, 34, 43, 45, 50, 70) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal.
