When the noted particle theorist Alessandro Strumia gave a talk at CERN near Geneva in 2018, he raised a storm of protest by suggesting that women in his discipline were somehow less capable than men. In response, a collection of physicists who gave themselves the endearing name Particles for Justice came together to issue a statement condemning Strumia’s remarks.

Last week, members of the group (who had remained in close touch after the Strumia incident) had a virtual meeting and decided to mount a light-speed response to the current global wave of pushback against racism following the death of George Floyd. They created the hashtag #Strike4BlackLives and designated Wednesday, June 10, as a day when academics should stop all they are doing—whether it be conducting research, holding seminars or writing papers—to highlight the racism facing Black students and faculty in higher education and throughout society.
