Today's #Mathober is "Jacobian." The Jacobian determinant helps us find how areas of rectangles are transformed when mapped into a new coordinate system. I used the Jacobian determinant to figure out how to cut an onion so that the pieces are most uniform. The math has been featured in the New York Times and, recently, a great article by the Pudding.
When I published all the nitty-gritty mathemat

Making an appearance on Page D4 of today's New York Times for my mathematical model of how to cut an onion optimally 😀. This makes me really happy, and feels surreal.

If any of you are searching for virtual speakers for an undergraduate audience (only multivariable calculus required), I would be happy to deliver my talk about cutting onions optimally called "Finding Mathematical Joy Cutting Onions." On its surface, this talk is about cutting onions optimally, but it is really an in-depth exploration into coordinate systems, Jacobians, and finding mathematical j

Sometimes mathematical research leads to unexpected beauty.
For the past five years, I've been working on building mathematical tools to analyze data that is non-uniformly sampled in time. To do so, my collaborators and I have developed ge…
