• Mathematics for Human Flourishing is name of both my book and a speech that spawned the book. The book (Yale University Press, 2020) is aimed at the general public. The speech was directed to mathematicians, and I gave it in my capacity as president of the Mathematical Association of America.

• Solve this math problem: the gender gap. An op-ed I wrote after Maryam Mirzakhani won the Fields Medal. Los Angeles Times, August 25, 2014.

​

• The Lesson of Grace in Teaching. This is probably my most shared piece of writing. This was a speech I gave after winning the Haimo Award, a nationwide teaching award for college faculty.  It appeared on my blog and was published in The Best Writing on Mathematics 2014.​

I've wrote a number of articles for MAA FOCUS when I served as MAA President, about teaching mathematics:

• Race, Space, and the Conflict Inside Us

• The Value of Struggle

• Mathematical Microaggressions

• The Secret Mathematical Menu

• To the Mathematical Beach

• Some Guidelines for Good Mathematical Writing
