**Abstract**

Granular materials are a vital component of many industries, including the pharmaceutical, mining, and food industries. Equally important, however, are the mathematical and computational questions raised in the course of modeling these materials. This talk will serve as a gentle introduction to the field, covering a range of applications from Engineering and Physics and explaining how Mathematics has been brought to bear on these problems. A deeper examination of steady-state flows through hoppers follows, with a survey of some recent intriguing results that may have some direct application to the development better industrial hoppers.
