Where are the monkeys?

The young lady strolled thru the National Zoo and finally paused in front of the monkey island. Mystified as to the whereabouts of the animals, she queried the keeper, "Where are all of the monkeys?"

"They're all back in the cave Miss." he responded, "It's right in the midst of the mating season."

"I see." she replied, "Do you think they'd come out if I offered them some of these peanuts?"

Smiling the keeper responding, "Well, I can't rightly say as I know Miss. Would *YOU*?"

Jakob Steiner

Died 1 Apr 1863 at age 67 (born 18 Mar 1796).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.”«
