Trisections and Totally Real Origami by Roger C. Alperin alperin@math.sjsu.edu Mathematical origami or paper folding methods, their relations to plane geometry constructions, and the corresponding algebraic theory of fields are explored. Special attention is made to the use of trisection and its construction by origami. Applications are made to the classical billiard problem of Alhazan.

**Quadratic Reciprocity in a Finite Group**

In 1872 Zolotarev gave an interpretation of the Legendre symbol that generalizes in a natural way to an arbitrary finite group *G*. We use this generalization to prove a law of quadratic reciprocity for *G* that includes the classical law when *G* is cyclic of prime order. Our proof combines the ideas behind one of the proofs of Gauss of classical quadratic reciprocity with two inventions of Frobenius: the Frobenius automorphism and the character table of *G*.
