Editors' Note

When longtime Glendale Community College mathematics professor Sid Kolpas moved from Southern California to Eastern Pennsylvania a few years ago, he learned that one of his new neighbors, Stu Ockman, was not only a fellow crossword puzzle enthusiast, but also a professional crossword puzzle constructor. Sid and Stu soon began work on the puzzle, "Mathematicians from A to Z," presented in Convergence in January of 2017.  The pair's second puzzle, "Mathematical Potpourri," appeared in both Convergence and Math Horizons in February 2018.

We are pleased to now present Kolpas and Ockman's third puzzle, "Here's Looking at Euclid."

This puzzle also appears on page 2 of the September 2019 issue of Math Horizons (Volume 27, Issue 1). Math Horizons is the vibrant, fun, and accessible MAA magazine for students, educators, practitioners, and enthusiasts of mathematics. If you are not already a subscriber, we urge you to visit the Math Horizons website to learn how to sign up for a personal or departmental subscription (or both). We thank Math Horizons editor David Richeson for his editorial and production assistance.
