Della Pietra Lecture Series Presents Professor Tadashi Tokieda (Cambridge University) February 8-10, 2016

20160208 Della Pietra Lecture Series

General Public Lecture 

Date: NOTE: Due to inclement weather, this event has been rescheduled for Tuesday, February 9, 2016
Wine and Cheese Reception: 5:00 pm, Simons Center Lobby and Art Gallery
Lecture: 6:00 pm, Simons Center Auditorium, Room 103
Title: “Science from a sheet of paper”
Starting from just a sheet of paper, by folding, stacking, crumpling, tearing, we will explore a rich variety of sciences, from geometry and magic tricks to elasticity and the traditional Japanese art of origami. Much of the lecture consists of actual table-top demos, which you can try later with friends and family.

So, take a sheet of paper. . .

Technical Talk for Faculty and Advanced Graduate Students

Date: Tuesday, February 9, 2016
Lecture: 1:00 pm, Simons Center Lecture Hall, Room 102
Title: “Chain reactions”
To every action, there is an equal and opposite reaction. However, there turn out to exist in nature phenomena where the reaction seems neither equal in magnitude nor opposite in direction to the action. We will see a variety of table-top demos and experimental movies, apparently in more and more violation of Newton’s 3rd law, and give an analysis of what is happening, discovering in the end that these phenomena are in a sense generic. The keys are shock, singularity in the material property, and supply of ‘critical geometry’.

20160210 Della Pietra Lecture Series 2

Special Presentation for High School Students

Date: Wednesday, February 10, 2016
Lecture: 11:00 am, Simons Center Auditorium, Room 103
Title: “Magic with a ribbon, paperclips, rubber bands”
What does it mean ‘to calculate’?
We usually think of numbers or of formulas. Using just a ribbon, paper-clips, and rubber bands, we’ll explore a sequence of magic tricks, and before you know it, you’ll find yourself doing sophisticated `calculations’ on objects that aren’t numbers or formulas at all. The magic is robust, so you can later show it off to friends and family.

Tadashi Tokieda is the Poincaré Distinguished Visiting Professor at Stanford and the Director of Studies in Mathematics at Trinity Hall, Cambridge. He grew up as a painter in Japan, became a classical philologist in France, and has been an applied mathematician in the US and elsewhere; he is also active in outreach in the developing world via the African Institute for Mathematical Sciences.




All of these lectures have been made possible by a generous donation from the Della Pietra family. The Della Pietra Lecture Series aims to bring world-renowned scientists to the Simons Center for Geometry and Physics to enhance the intellectual activity of the Center and also bring greater awareness of recent and impactful discoveries in Physics and Mathematics to the Long Island community.
