A friend found this Sangaku, which if you don’t know (from Wikipedia) are Japanese geometrical problems or theorems on wooden tablets which were placed as offerings at Shinto shrines or Buddhist temples during the Edo period by members of all social classes. So here’s what she sent me (from here) The question that I’m attempting to figure out is: what is the radius […]| Continuous Everywhere but Differentiable Nowhere
Like in my last post, I want to share a math problem I was working on for a summer professional development I’m doing. This was part of the problem set that the PD organizer Justin Lanier wrote up. The problem is outlined here: As part of this professional development, we started filling in a spreadsheet […]| Continuous Everywhere but Differentiable Nowhere
This is going to be a writeup for a math problem I’ve been working on for a professional development thing I’m doing this summer. The question related to soap bubbles. Because I just wa…| Continuous Everywhere but Differentiable Nowhere
In my last post, I shared a question posed to me by a student. Essentially, it boiled down to: can we algebraically prove that the following will always be an integer? I shared it with two friends in my department because they both really love combinatorics like me. One gave me some really nice ways […]| Continuous Everywhere but Differentiable Nowhere
Today in class, a student asked a question that stumped me. I haven’t yet given myself a lot of time to think about it, but I went into the city after school for something and on the subway ride home I had my audiobook on and I basically didn’t “hear” anything because my mind kept […]| Continuous Everywhere but Differentiable Nowhere
On Thursday, after school, I hopped in an Uber to the airport. I was flying to a conference, the “Teaching Contemporary Mathematics” conference (TCM) held at the North Carolina School of Science and Mathematics. I think I’ve been at least twice over my career, maybe three times, and always found it to be a really […]| Continuous Everywhere but Differentiable Nowhere
