11/6 -- LAMC High School: Title: Paper Folding and Construction I -- Yingkun Li

Many amazing constructions can be accomplished using straightedge and compass. However, one cannot trisect arbitrary angle or construct cube root 2. In this talk and the next one, we will look at simple ways to execute the above constructions by folding papers, and consider the possibilities when different folding moves are allow.
