Natural Blonde Paint
A new paint store just opened up by my place, so I decided as any red-blooded, sexually repressed young lad to pay it a visit.
When I went in I saw signs all over advertising the newest color: "Natural Blonde". There weren't any samples around, so I asked the clerk to describe it to me.
He replied, "Natural Blonde? Wonderful new paint: not too bright, but spreads easily!"
MAGIC SQUARE: Calculate A-B-C
The aim is to place the some numbers from the list (7, 10, 11, 12, 14, 16, 52, 55, 57, 71) 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.

Richard Christopher CarringtonDied 27 Nov 1875 at age 49 (born 26 May 1826).English astronomer who, by observing the motionsp of sunspots, discovered the equatorial acceleration of the Sun; i.e., that it rotates faster at the equator than near the poles. He also discovered the movement of sunspot zones toward the Sun's equator as the solar cycle progresses. Carrington devoted himself to the study of sunspots and his work, extending from 1853 to 1861, was collected in Observation of the Spots of the Sun (1863). Carrington also was the first to observe a sun flare (1859). He was observing a prominent group of sunspots on 1 Sep 1859, when suddenly "two patches of intensely bright and white light broke out." which brightened rapidly and decayed. The flare he had seen was of the rare variety that is visible in white light.(Image: detail of a drawing by R.C. Carrington, showing the location of the flare he observed while making a drawing of an active region. Reproduced from his 1860 paper in Monthly Notices of the Royal Astronomical Society) |
