Michael Tomlinson of Virginia and his daughters, 4 year-old Ruth (left) and 2 year-old Twilight sit on The National Mall lawn in Washington, D.C. awaiting the beginning of the March for Science rally on Saturday, April 22, 2017. “The Science March is dear to me because I’m a science teacher in Loudoun County. I understand the importance of right thinking and understanding the world. … I think most scientists are interested in finding the truth. It’s important for (my daughters) to see that a lot of people think the same way. It’s scary to think we can grow up in a world where people reject simple facts,” Tomlinson said.
