Physics Today Magazine Hires New Editor-in-Chief

Position Statement

WASHINGTON, D.C., Oct. 6, 2015 — The American Institute of Physics (AIP) announced today that physicist, editor and science writer Charles Day will soon assume the role of Editor-in-Chief of Physics Today ( the world's most influential and closely followed magazine devoted to physics and the physical science community.

Published continuously since 1948 as AIP's flagship magazine, Physics Today has kept its readers abreast of almost every major development in the field through breaking news stories and in-depth features. Luminary authors who have published in the magazine include dozens of Nobel laureates and scores of other international leaders in research, education and policy. Among these past authors are Albert Einstein, Richard Feynman, Enrico Fermi, Werner Heisenberg and Steven Chu.

Day will become the seventh Editor-in-Chief of Physics Today. Previously, he was a senior editor at the magazine and is currently the online editor, overseeing its Web content and social media strategy. He succeeds Stephen G. Benka, who has led the magazine since 1994.

"Charles is a talented writer and editor, and his efforts to build the Physics Today community online have resulted in a huge following on Facebook and Twitter," said AIP CEO Robert G.W. Brown. 

Day first joined AIP 18 years ago following postdoctoral fellowships at Japan's Institute of Space and Astronautical Science and NASA's Goddard Space Flight Center. He received his PhD in X-ray astronomy from the University of Cambridge in 1988.

Originally hired at Physics Today to be an editor, Day has filled a number of significant roles at the magazine, said Brown. These include editing obituaries and feature articles; writing news stories; running the monthly "Search and Discovery" department; and serving as the magazine's online editor, responsible for all editorial content that doesn't originate in the monthly print magazine.

"Physics Today has the best team of professional editors and staff in the business," said Day. "I'm honored to have been chosen to lead them into the magazine's great future."

Besides his work at Physics Today, Day also writes the monthly "Last Word" column for Computing in Science & Engineering, a bimonthly magazine published jointly by IEEE Computer Society and AIP. He lives in the Capitol Hill neighborhood of Washington, D.C. with his wife, Jan, and their Airedale terrier, Echo. 



Charles Day began his career at Physics Today in 1997 as an Associate Editor after spending eight years as an astrophysicist, nearly seven of which were at NASA's Goddard Space Flight Center in Greenbelt, MD. He received his PhD in Astronomy from the University of Cambridge in 1988, pursuing research on X-ray emissions of neutron stars, black holes and other cosmic objects. Prior to graduate school, Day obtained a physics degree from Imperial College London.

 At Physics Today, Day rose to the position of Senior Editor in 2003, picked up duties for the magazine's Last Word column in 2009 and began working as the Online Editor in 2010. He has overseen sections and columns at the magazine, including Politics and Policy, Down to Earth, Physics Update, and News Picks. He also provides color commentary and opinion through The Dayside, his professional personal blog.
