From the YouTube description:
As an internationally competitive baton twirler in Toronto, Canada, Nicole Johnson impressed audiences with the degree of difficulty found in her acrobatic routines. As a Jayhawk, she found a way to express that complexity using another talent — math. Nicole Johnson received an Undergraduate Research Award for “Baton Twirling into the Fourth Dimension.” Working with associate professor Estela Gavosto, she translated her astonishing performances into equally beautiful graphs. “Just being able to show that there’s this different side of math than what you normally see — that is one of the really cool outcomes of this project,” says Johnson, who graduated in May 2019 with honors in both mathematics and engineering physics.
