Marin Winford, age 5, tells everyone why she came out for the March for Science in Quincy on April 22. Marin’s mom backs her up. It was all about clean water for Marin. She roused the crowd by asking “How many of you like clean water? How many of you like dirty water?” It was no contest. Huck Winford, age 7, prepares to discharge a “trevuchet” with the help of Christopher Clements preceding the March for Science in Quincy on April 22. Clements is a physicist and microbiology student at FRC. Whereas a catapult uses stored tension to fling material, a trevuchet uses stored gravity in the form of an elevated weight (in this case, rocks in a steel can). Photos by Steve Wathen Approximately 80 to 100 citizens, and a dozen dogs, express their support of science as the basis for making government policy decisions at the March for Science in Quincy on April 22. Christopher Clements, left, and Tirian Shirley release their “rotating wings,” in this case Dixie cups taped together bottom to bottom, preceding the March for Science in Quincy on April 22. Shirley’s “rotating wing” can be seen at the upper left of the image. All wings rely on differences in air pressure below versus above the wing to provide lift, the lower pressure above causing the wing to rise. A conventional wing relies on wing shape to provide this difference in air pressure using the Bernoulli effect. A rotating wing relies on rotation of a cylinder, called the Magnus effect. Both Clements and Shirley are students at FRC and enjoy sharing their love of science.
