Sidney Robert Nagel is an American physicist and the Stein-Freiler Distinguished Service Professor at the University of Chicago, where he is affiliated with the Department of Physics, the James Franck Institute, and the Enrico Fermi Institute. His research focuses on complex everyday physics such as "the anomalous flow of granular material, the long messy tendrils left by honey spooned from one dish to another, the pesky rings deposited by spilled coffee on a table after the liquid evaporates or the common splash of a drop of liquid onto a countertop."[http://nagelgroup.uchicago.edu/Nagel-Group/index.html Home page] of the Nagel Group of the University of Chicago, accessed March 10, 2012 His work includes high-speed photography of splashing liquids and drop formation.
