“The Physics of Foam”
Everyone is familiar with a head of foam at the top of their beer glass, but do they understand the surprising properties of that foam? How can it be white and solid when it’s made mostly of gas and a little liquid, neither of which is white or solid? Douglas Durian will explain how foams change over time and some of the excitement they offer as a modern research topic in fundamental physics and mathematics.
