I’m honored to report that I’ve been asked to deliver this year’s John Wesley Powell Memorial Lecture.

The John Wesley Powell Memorial Lectures were inaugurated in 1929 in honor of the distinguished geologist and leader of the first expedition down the Colorado River through the Grand Canyon. Each year since then, with the exception of the years during WWII when the Division did not hold meetings, SWARM has invited a distinguished scholar to deliver a lecture at the Annual Meeting on a subject of his or her choosing. An attempt has always been made to select speakers who represent as wide a diversity of scientific endeavor as possible. Some of the previous Powell lecturers have included Oliver Sacks
