Talking Baseball

This series of blog post style notes grew out of a DRP on sabermetrics, the mathematics of baseball. These are aimed at a broad audience, but assume some familiarity with the game of baseball.

• What is a Double Worth?
• When Should You Steal Second Base?
• Heuristics for Unlikely No Hitters
• A Case Study in Win Probability and Leverage
• Scoring Without Hits
• Run Scoring by Inning in 2021

Learning Through the Ranks

Learning Through the Ranks: A Graduate Student Blog is hosted on the MAA's Math Values blog. I wrote for this blog about my experiences as a PhD student.

AMS Grad Student Blog

From 2019 to 2021, the AMS Graduate Student Blog featured writing by and for graduate students. It is now retired, but you can still view the archived version. I was a writer for this blog in Fall 2021.

Expository

• To study for my algebraic geometry qual, I made this list of definitions, results, and practice questions (it's long but certainly not exhaustive).
• Here are some expository notes I wrote while learning about abelian categories and derived functors.

Math Circle Lessons

As an instructor for Emory Math Circle, I have developed many lessons aimed at engaging middle and high school students in mathematics exploration. Below are some of my favorites.

• The Mathematics of Press Your Luck
• The Kakeya problem

You are welcome to adapt and use these, though I ask that you attribute credit to me in any written materials you share (e.g. if you write an adapted lesson plan, please include "adapted from a lesson on LESSON_TOPIC written by Christopher Keyes and available at THIS_WEBSITE").
