S'bastien Dartevelle, a Ph.D. student at Michigan Tech, created this Web site devoted to the understanding of "granular flows, granular processes, fluid dynamic, supercomputer modeling, and grain-size analysis of Volcanology, Geophysics, and Physics." Providing challenging materials in an accurate and simple manner, students can easily learn about topics including granular theory and granular medium. Users will find essential facts about viscous phenomenon in the newly added link, All I Wanna Know 'bout Viscous Stress. Educators and students can view the Plinian Cloud simulations. The author also provides mathematical equations, atmospheric profiles, and much more.
