The Physics of Coffee Rings: An Untypical Physicist's Journey

Professor Sidney Nagel of the University of Chicago has revolutionized the field of physics by studying everyday phenomena like coffee stains, raindrops, and sand flow. He turned his attention to 'soft matter' largely overlooked by most physicists, developing theories of 'jamming' to explain the flow (or lack thereof) of sand and traffic. Nagel's work is not only scientifically significant but also aesthetically pleasing; images from his experiments have graced museum walls. His research has earned him prestigious awards like the Oliver E. Buckley Prize and the American Physical Society's Medal for Exceptional Achievement in Research, highlighting its impact and unique perspective.
