Cathleen S. Morawetz Pin
Series One, Pin No. 05
Dr. Morawetz was a Canadian mathematician who spent much of her career in the United States. Morawetz's research was mainly focused on the study of the partial differential equations governing fluid flow, particularly those of mixed type occurring in transonic flow. (How air moves over a foil to create a boom!)
To commemorate her research the pin features an illustration of fluid flow over a wing. The different colors represent different pressures of air over the foil.
2 inches at the tallest point. Black dyed metal plating with rubber clasps.
