Dust off those old similar triangles, and get ready to put them to new use in looking at art! We're going to explore the mathematics behind perspective paintings-a mathematics that starts off with simple rules, and yet leads into really lovely, really tricky mathematical puzzles. Why do artists use vanishing points? What's the difference between 1-point and 3-point perspective? What's the difference between a perspective artist and a camera? We'll look at all of these questions, and more.
Biography:
Annalisa Crannell is a Professor of Mathematics at Franklin & Marshall College, where she has been since 1992. Her primary research is in topological dynamical systems (also known as "Chaos Theory"), but she also is active in developing courses on Mathematics and Art. She has worked extensively with students and other teachers on writing in mathematics, and with recent doctorates on employment in mathematics. She especially enjoys talking to non-mathematicians who haven't (yet) learned where the most beautiful aspects of the subject lie.
