MAA Found Math
Each week, the Mathematical Association of America website posts a new math-related photo that was submitted by an MAA member. The photo reposted here is a decorative Venn Diagram on a ceiling light that was featured on May 31, 2011. The photographer was Joy Hsiao of Brooklyn Technical High School. Visit the MAA Found Math gallery to view more of these fascinating photos.
