The ABC's of Marriage
After being married for 25 years, a wife asked her husband to describe her.
He looked at her carefully, then said, 'You are A, B, C, D, E, F, G, H, I, J, K.'
'What does that mean?' she asked suspiciously.
He said, 'Adorable, Beautiful, Cute, Delightful, Elegant, Foxy, Gorgeous and Hot!'
She beamed at him happily and said: 'Oh, that's so lovely! But what about I, J and K?'

Ralph WyckoffBorn 9 Aug 1897; died 3 Nov 1994 at age 97. Ralph (Walter Graystone) Wyckoff was an American scientist, a pioneer in the application of X-ray methods to determine crystal structures and one of the first to use these methods for studying biological substances. He became famous in two areas of structural research: X-ray diffraction and electron microscopy. He developed a new technique of 'metal shadowing' for observation with the electron microscope. A specimen, such as a virus, is placed in a vacuum together with a heated tungsten filament covered with gold. Vaporized gold coated the side of the specimen nearest the filament, leaving a 'shadow' on the far side. This allowed better estimates to be made of their size and shape, as well as revealing details of their structure. |
MAGIC SQUARE: Calculate A+B*C
The aim is to place the some numbers from the list (2, 4, 12, 21, 23, 26, 30, 31, 64, 70, 72, 80, 90) into the empty squares and squares marked with A, B an C.
