Office Hours with Non-Mathematicians

Mathematics is often present as structure before it is present as calculation.

Then I pull out one idea, build a simplified worked example, and reveal the mathematical ideas underneath—without assuming advanced mathematics.

Interviews are underway and articles are in development, including stories about matching people to opportunities, gravity models of international trade, and networks in archaeology. This page will become the home for new stories as they are published.

Three conversations, three fields, and three different ways mathematics helps us understand the world.
