John Kilbourne, professor at Grand Valley State U., in Allendale, Mich., came to the March for Science in Washington, D.C., dressed as Galileo, the founder of modern physics and astronomy who was persecuted for standing by his scientific findings.
Marches supporting science were held around the world on April 22, the annual celebration of Earth Day.
Signs of the times: Rain did not impede the proliferation of posters.
Steve Trombulak, professor of biology at Middlebury College, in Vermont, and Owen White, professor of epidemiology at the U. of Maryland School of Medicine, sought shelter under trees on the National Mall as they waited for the march to begin.
Keith Salazar, a toxicologist and West Virginia U. graduate, and his wife, Jen Salazar, a graduate student at the U. of Maryland, marched as the Muppet Show characters Dr. Bunsen Honeydew and his faithful assistant, Beaker.
A graduate student at Virginia Tech, Donal Murphy works in the aerospace industry and marched because he believes funding research is key to his industry.
Nerd alert: Some marchers quoted and had posters of the legendary Star Trek character Mr. Spock. Other marchers used signs to express their anger with the Trump administration.
Patty Reeber, a D.C. librarian, didn’t let the rain dampen her spirits as she and other librarians stood together in solidarity.
Patrick Kolence, Allison Inanoria, and Kevin Allan are three of the nine students that Foothill College, in Los Altos Hills, Calif., sent to the march to interview scientists for a forthcoming video project. The college sent three faculty members as well.
Marchers came together to march from the Washington Monument to the U.S. Capitol.
Correction (4/24/2017, 12:01 p.m.): This article originally referred incorrectly to a legendary character on Star Trek. He is Mr. Spock, not Dr. Spock. The latter was the legendary baby doctor. The article has been updated to reflect this correction.
