The fifteenth Math Webinar in English took place on Wednesday, May 4th, 2022 from 5 pm until 6 pm with Annalisa Crannell, Associate Dean of the Faculty and Professor of Mathematics at Franklin & Marshall College, as our invited speaker. This virtual event was free and open to the general public.
In this fifteenth Math Webinar in English, Annalisa Crannell presented on “Drawing Conclusions from Drawing a Square.” The speaker explained that perspective art was the spark from which projective geometry grew. Annalisa Crannell pointed out that one of the most surprising results of projective geometry is that every quadrangle is the perspective image of a square. The speaker described applications of this result in computer vision, in photogrammetry, among others, and mentioned the works of art of Albrecht Durer, Hans Holbein the Young and Julian Beever. This virtual event was co-organized by the Mathematical Association of America (MAA).
