11th Annual Cantrell Lectures

Monday, May 2, 2005 4:00p.m., Physics Bldg., Room 202 Basic Twistor Geometry; Physical Motivations Twistor theory is motivated by the idea that the union between space-time structure and quantum-mechanical principles may well involve non-standard quantization procedures. Two guiding principles underlying the twistor approach are holomorphicity (complex analyticity) and non-locality, these seeming to be features that an appropriate "quantized…

13th Annual Cantrell Lectures

Wednesday, April 11, 2007 3:30 p.m. Physics Bldg., Room 202 Title of talk: Origami, Linkages, and Polyhedra: Folding with Algorithms Abstract: What forms of origami can be designed automatically by a computer? What shapes can result by folding a piece of paper flat and making one complete straight cut? What 3D surfaces can be cut open and unfolded into a flat piece of paper without overlap? When can a robot arm or protein be untangled or…

15th Annual Cantrell Lectures

Wednesday, April 15, 2009 3:30pm, Miller Learning Center, Room 102 Title of talk: Mathematics and the Diversity of Cultures Mathematics has played a vital role in every culture. Looking at the three cultures -- China, India and the West -- one can, to some extent “replay” the history of math from three different starting points. Sometimes one finds that it developed with strong parallels but sometimes with deep differences. The development of…


16th Annual Cantrell Lectures

Monday, April 5, 2010 3:30pm, Room 102 Miller Learning Center Title of talk: Curve shortening flow and Mean Curvature flow Abstract: Mean Curvature Flow is the oldest of the geometric flows (Ricci flow being another example of a geometric flow). originates in material science where it has been studied at least since the 1940s. is an example of an evolution equation where a surface (or hyper-surface) moves in the direction where the area…


17th Annual Cantrell Lectures

From Schubert calculus to equivariant cohomology The aim of this series of lectures is to sketch how the enumerative geometry of the 19th century has grown into the thriving field of equivariant cohomology in the 20th and 21st centuries.    We will begin by sketching the history of the subject, starting from Steiner’s question (posed in 1848): how many conics are tangent to 5 given plane conics?  Answering such questions…


22nd Annual Cantrell Lecture Series

22nd Annual Cantrell Lecture Series TUESDAY, April 5, 2016 3:30-4:30pm, Miller Learning Center, Room 171 Title of talk: Through the looking glass: Symmetry, the fourth dimension, and beyond  Description: Why are our mirror images reflected left-right but not up-down? What does the fourth dimension look like? How is it possible that a square box can be big enough to hold only one round marble of a given size, but the marble only takes…


18th Annual Cantrell Lectures

April 25 - 27, 2012 Wednesday, April 25, 2012 3:30pm, Miller Learning Center, Room 102 Title of talk: Mathematics of Crime Abstract: There is an extensive applied mathematics literature developed for problems in the biological and physical sciences. Our understanding of social science problems from a mathematical standpoint is less developed, but also presents some very interesting problems, especially for young researchers. This…
