UO physicist combines science and rock climbing in signature course

Physics Professor Graham Kribs and students in the Science of Climbing course measure the load on a climbing rope and pulley configuration using a force meter and a bundle of tires for weight.

The first year Graham Kribs was a faculty member at the University of Oregon, he spent his lunch breaks at the UO Recreation Center taking a rock-climbing course. Though the theoretical particle physicist had a passion for the physical sciences, he also had a passion for physical activity. It wasn’t until almost 15 years later, though, that Kribs was able to combine the two and make a one-of-a-kind class.

After taking a rock-climbing course from Dan Crowe, the assistant director of physical education at UO, Kribs and Crowe got to chatting about making a class that combined physics and climbing. Crowe emphasized the resources specific to Oregon, such as the Pacific Northwest outdoors and the UO rock climbing walls, and Kribs was even more excited about making a multi-subject course. 

Physics is far from the only discipline at UO capitalizing on the campus's setting.

“Surfing on the coast, skiing in the Cascades, and world-class kayaking, climbing, hiking, and biking are all within a couple of hours of Eugene and other parts of the Willamette Valley,” Nick Kohler, an instructor in the department of geography, said. Kohler teaches Geographies of Outdoor Adventure, which looks at important cultural, natural and economic transformations within popular outdoor activities like hiking and snowboarding. He finds the inspiration for his course in the geography of Oregon. 

Kohler appreciates Oregon as a setting for a course like his because of the diversity and accessibility of the landscapes used for outdoor adventure sports. “Oregon’s history of fairly strict land use protections, public access to outdoor spaces, and robust conservation ethic also helps quite a bit,” he said.

Three years ago, Kribs opened his class, PEO369M: Science of Climbing, up for enrollment. His two-credit course, which allows students to make hands-on connections between rock climbing and physics, is usually made up of four to six students, which he hopes to grow up to 10 in future terms. 

“It's really about uncovering the science behind how climbing is done, how equipment is designed to meet specification, and ultimately how to make climbing and related activities as safe as they can be,” Kribs said.

Physics Professor Graham Kribs calculates physical forces after testing force in an experiment with climbing equipment.

Using spaces in the Rec Center and Gerlinger Annex, Kribs and his class measure the force exerted in various pulley configurations, test the strength of equipment by loading it to the breaking point and even probe helmet safety using a juicy crash test dummy.

“We put a small watermelon in a helmet as a proxy for the head,” Kribs said. “And again, this is not precise science. This is to get some qualitative understanding of how to think about the role of different helmets and why they're designed the way they are.”

JD Merritt, a fourth-year PhD candidate in physics, is a graduate employee in Kribs’ Science of Climbing course. According to him, the hands-on aspect of the course is what allows students to engage so deeply with the material.

“I think everyone has an intuitive understanding of physics from their everyday lives, but this makes it so clear that nature really is physics, whether we go through math on a chalkboard or not,” he said.

Although the class has mostly drawn nonmajors, each student leaves the class with a newfound appreciation for the physics behind rock climbing. The math may seem daunting at first, Kribs says, but once an experiment takes place, students become much more engaged.

“It’s fun to watch that transition from default skepticism to a full engagement in the topic,” Kribs said. “And that, I think, is one of the joys of doing this.” 

Along with the indoor climbing walls at the Rec Center and Gerlinger Annex, Kribs the sense of place and culture of outdoor activity in the Pacific Northwest makes courses like this flourish at the University of Oregon.

“We're sort of able to fuse two awesome things about Oregon into one,” said Kribs. “We can combine the awesome outdoor pursuits program and what they're able to do with the science side of the College of Arts and Sciences.”
