Drawings of Pendulums

The figures reproduced here are the paths of oscillation of two or more pendulums, coupled together so that their movements can be recorded. The apparatus was constructed by Prof. Alfred Gysi of Zurich. These images are published in the article : "Artistry of the Pendulum" by Hans Naef on page 436 of Graphis, N°16 1946.
