Program Description

We will use origami folding techniques (on a square piece of paper) to discover how we can chop up a line fairly or at least close to fairly. Students will be expected to provide justifications for the approximation method using their own ideas. (Spoiler alert: continued fractions may lurk its elegant head!) Along the way, they will likely analyze binary representations of decimals or even interpret the process of approximation as a discrete dynamical system. They will also be encouraged to offer a proof of the exact method of division. Finally, we will fold a helix using these ideas to investigate some limiting properties. There will be purely geometric and analytic means of approaching a limit problem, depending on the taste of the students. We shall encourage drawing pictures, providing rigor, or a combination of both.


Open to school students from 10 to 15 years in Bengaluru. Please register using the registration link above, for group participation write to ''. Participation is by invitation only.

About the Speaker

I enjoy the interplay of physics and mathematics, and try to see it everywhere around me. My interests are in teaching and understanding problem-solving as a creative process. I am affiliated with the Academic Talent Development Program, University of California, Berkeley, where I teach physics and mathematics, including international students visiting UC Berkeley. I mentor students interested in teaching math and physics and advise teachers on curriculum development as well as develop problems for international physics competitions. I also teach physics at Proof School.
