Escher ' s Print Gallery and the Land O'Lakes Effect

One of M. C. Escher's most intriguing works depicts a man standing in a gallery and examining a print of a city that contains the building that he himself is standing in. This picture, Print Gallery , contains a mysterious white hole in the middle. See <<http://www.mcescher.com/Gallery/
recogn-bmp/LW410.jpg>>.

Working with Hendrik Lenstra, the speaker showed that some well-known mathematical ideas could be used to show that what Escher was trying to
achieve in this work has a unique solution. This discovery led to a way to fill the void in Escher's print. With help from artists and computer scientists, a completion of the picture was constructed at the Leiden University. The white hole turns out to contain the entire image on a smaller scale, a phenomenon that, in the Dutch language, is called the Droste effect, after the Dutch chocolate maker Droste.

In Minnesota, this might be known as the Land O'Lakes effect, since a siimilar construction appears on packages of Land O'Lakes butter: the maiden is holding a package with the image of the maiden holding a package, and so on. In the talk the mathematics behind Escher's print and the process of filling the hole will be explained and visualized with computer animations.

Study Abroad and Reserch Opportunities for Math/CS Students

Are you thinking of majoring in math, cs, or stats and want to study abroad or do research with a faculty member? Wonder how to have a study abroad experience that is not linked to math or cs and still major? Want to do an intensive math program abroad? Want to use your stats, cs, or math skills at a summer internship? Come hear from faculty and students and find out answers to these questions, and more!
