I just love that mathematicians are so dry. I can't recall who the mathematician was, but when presented with a paper, he studied it very carefully for several days, after which he pronounced it "obvious". I wonder if any of the ancients knew the Dandelin construction for ellipses. At 12:14 PM 6/1/2009, N. J. A. Sloane wrote:
