Adrien Treuille, an assistant professor in the computer graphics group at Carnegie Mellon University, describes how better physics simulations could have implications in fields as diverse as architecture, racing, and medicine.
Swimmer Ariana Kukors presses her fingers into a device built to measure the force she generates with her freestyle kick. (She doesn’t hold on to anything.) The red vertical line shows the amount of force at a point in time. Kukors’s kick is strong and consistent, which is why the wave signal generally has the same amplitude throughout the recording.
