The brightest dog

Two dog owners were bragging about the intelligence of their pets. “The brightest dog I ever had,” said one, “was a Great Dane that used to play cards. He was great at poker, but finally a friend complained about him and I had to get rid of him.”

“You got rid of him, a bright dog like that?” exclaimed his friend. “A dog like that would be worth millions.”

“Had to,” the first man replied. “I caught him cheating.”

Jakob Steiner

Born 18 Mar 1796; died 1 Apr 1863 at age 67.Swiss mathematician who was one of the greatest, contributors to projective geometry. He discovered the Steiner surface which has a double infinity of conic sections on it. The Steiner theorem states that the two pencils by which a conic is projected from two of its points are projectively related. He is also known for the Poncelet-Steiner theorem which shows that only one given circle and a straight edge are required for Euclidean constructions. His work included conic sections and surfaces, the theory of second-degree surfaces and centre-of-gravity problems. He developed the principle of symmetrization (1840-41). In 1848 he ws the first to define various polar curves with respect to a given curve, and introduced the “Steiner Curves.”«
