Saturday Physics for Everyone

Add to Calendar 11/10/2018 10:15 am 11/10/2018 America/Chicago Saturday Physics for Everyone DESCRIPTION:

Crackling noise arises when a system responds to changing conditions through discrete, sudden events spanning a broad range of sizes. A wide variety of physical systems exhibiting crackling noise have been studied, from earthquakes to paper crumpling.   The regular behavior that appears in crackling across a huge range of sizes allows us to use a trick called “universality” to describe these systems using very simple models.  I will describe these ideas using results from a model of crackling noise in plastic deformation of materials, magnets, earthquakes, the brain, and stars.
